Frequently Asked Questions

Heating

  • Homeowners should have maintenance service on their boiler or furnace system at least once a year. This will help prolong the heater system’s life span and lower repairs and utility costs.

  • Heater maintenance is a lot like car maintenance. Routine furnace maintenance is the key to helping your heating system perform as long as possible.

  • Here are a couple steps you can take to keep your family protected from carbon monoxide:

    • Warm up your car outside of your garage. Cars are a significant source of carbon monoxide poisoning, so do not leave yours going in the restricted space of a garage. The same is true for gas equipment such as lawn mowers or snowmobiles.
    • Don’t run ovens or grills as heaters. These appliances are safe when used right but can create carbon monoxide when used for an extended period of time in confined spaces.
    • Don’t turn on a gas generator indoors because it produces fumes.
    • Have your chimney inspected by a specialist. This ensures chimneys and vents aren’t blocked and are connected appropriately.
    • Confirm gas appliances are operating correctly, particularly your heater. You can ensure efficient, safe operation by arranging for routine furnace maintenance with A-Plus Service Experts.

  • Your house’s air filter should be changed routinely, typically every 30 to 60 days.

  • Routine heating maintenance fees can vary, so please check our Maintenance+ membership page to see detailed tune-up costs.

  • Annual maintenance plans are definitely worth the cost for several reasons. Benefits of furnace maintenance plans include automated check-ins, no trip charge costs, priority service and others.

  • If you want to include heater tune-ups with other important services, consider signing up for our Advantage Program™, which can assist in keeping your warranty in good standing.

  • A popping disturbance is a common sign of an insufficient duct design. This occurs when there’s more airflow than your ductwork can manage.

    Troubles with your ductwork can lead to other ventilation and air quality problems, such as:

    • Significant noise
    • Greater energy needs
    • Early system malfunction
    • Irregular heating and cooling
    • Broken AC compressor in the summer
    • Too hot furnace or heat pump in the winter
    • Mold growth inside ducts

    Call a qualified company in Waldorf like A-Plus Service Experts to examine your home’s ventilation system. We can offer suggestions for duct repair or installation.

  • It’s common for your heating and cooling equipment to make a little noise. However, hearing strange or loud noises could mean there’s an electrical problem or trouble with the blower fan or capacitor. If not fixed, there can be serious (or expensive) consequences later on.

  • This could be because of improper thermostat settings. Check that the fan blower is set to “auto” and not “on.” Other factors include a damaged pilot light, restricted air flow due to dirty or clogged furnace filters, or blocked condensate lines. If issues persist, call A-Plus Service Experts for prompt repair.

  • Most companies will recommend heater replacement when the cost to repair your system is more than half the cost of a new system. At times, a repair won’t restore the heating system to a minimally effective level. The life expectancy for most furnaces is 15-20 years, and so replacement is generally recommended during that time frame. For more considerations, visit our blog covering more details on when to repair or replace your furnace.

  • It’s often less expensive to replace your furnace and air conditioner at the same time. Plus, you’ll also enjoy greater energy efficiency year-round. Here’s when you should replace both systems at the same time:

Cooling

  • Small tasks like changing the air filter and keeping your equipment maintained can go a long way in increasing energy efficiency. Check out our full guide for savings you can earn by keeping your HVAC system healthy.

  • Central air conditioners are ducted HVAC units that extract heat from your house. There are also heat pump air conditioners, which draw out heat with a reversible flow of coolant, as well as ductless mini-splits.

  • The right sized air conditioner depends on the size of your home, the local climate and many other factors. You need to properly size the AC system to ensure maximum energy efficiency.

  • British thermal units are a form of measurement used in A/C to illustrate how much energy your AC unit needs to absorb heat. If it mentions 10,000 BTUs, the model is capable of absorbing that much heat each hour.

  • Routine maintenance is extremely beneficial for your air conditioner. While it’s not strictly required, it’s an excellent investment in the energy efficiency and overall performance of your HVAC system. In most cases, having regular maintenance and service also keeps the manufacturer’s warranty valid.

  • Ductless air conditioning doesn’t use air ducts to transport cool air through a building. Instead, indoor air units blow the conditioned air directly into the room or area they’re installed in.

  • SEER means Seasonal Energy Efficiency Ratio, which gauges how efficiently your air conditioner is cooling over its busiest season.

  • Heat pumps are extremely energy efficient, but may start to lose efficiency in really cold weather. Check out our guide for figuring out if a heat pump or air conditioner is right for cooling your home.

  • The cost of a/c services depends on the make and model, the severity of the issue and other factors. For lots of common repairs, you might expect to pay a few hundred for parts and labor.

  • The cost for AC installation largely depends on the size of the home and the replacement air conditioner unit the homeowner chooses. The installation amount can be well over $12,000, depending on the size of the home and the replacement AC that is chosen for the home. Our Advantage Program helps homeowners get access to the AC systems they need for one low monthly payment.

  • It’s often less costly to replace your furnace and air conditioner at the same time. Plus, you’ll also take pleasure in greater energy efficiency year-round. If your systems are older than 15 years or you need a high-efficiency model or smart thermostat, you should have a new AC and furnace installed together.

  • We install all types of cooling systems, including central air conditioner systems, geothermal, heat pumps and ductless mini-splits. Schedule a quote to find the right fit for your home by calling A-Plus Service Experts at 301-747-3140.

  • We offer HVAC financing options as well as the HVAC Advantage Program, which covers everything from new units to repairs* and maintenance for a low monthly cost.

  • Some of the work during an ac tune-up includes a fundamental AC maintenance checklist:

    • Tightening electrical connections. This ensures your system is working safely.
    • Lubricating parts. When your system isn’t lubed, resistance from moving parts can cause it to break down more regularly.
    • Cleaning the condensate drain line. Cleaning this line takes care of mold and clogs, which can cause leaks.
    • Cleaning the condenser coil and evaporator coil. These coils become dirty gradually, limiting airflow and its ability to absorb heat.
    • Straightening coil fins. Aluminum fins on the coils can bend and decrease airflow.
    • Examining system controls. This makes sure your system is starting, running and shutting down properly.
  • There are often different kinds of maintenance plans and pricing. Check out our memberships page to learn about our tiered maintenance memberships.

  • Routine air conditioner maintenance is important to keeping your equipment operating efficiently, and it can reduce the need for unexpected replacements.

  • Some key tells that you need AC maintenance service on your unit is if your home has poor airflow or hot and cold spots, leaks, unusual noises or warm air coming from the vents.

  • Check this full guide to AC maintenance for various things you can do. One of the main things homeowners can do to help upkeep their system, other than having annual yearly or seasonal maintenance done, is to change your AC unit’s air filter every 60-90 days, or 30 days if you have family pets. Changing your filter on a routine basis can extend the life span of your system by reducing wear and tear on the unit, preventing clogs and improving airflow. Using a higher quality HEPA filter can also help maintain the AC unit’s efficiency and reduce instances of sickness in your home.

  • A trip fee is the expense associated with the time and travel for a Service Experts professional coming to your home. Look at our offers for printable discounts for your future air conditioner service.

  • Yes. Our pros are just a quick trip away to assist with an AC repair or replacement during an emergency.

    • AC leaking water. This is usually the PVC pipe going out of the AC unit. Leaking refrigerant can cause ice to collect on the coils and drip water. AC repair is needed when this takes place and should be treated as an AC emergency.
    • Air conditioner won’t turn on. Homeowners can first check the thermostat settings and look for a tripped breaker on the electrical panel. If the breaker is tripped, it may not require a repair call.
    • AC not blowing cold air. Double check the thermostat settings are on the correct temperature and that your thermostat has power. Then replace the filter. You can also verify the AC unit isn’t obstructed with debris, and that it isn’t leaking refrigerant. If you find a leak or your AC is still blowing hot air, call us at 301-747-3140 for emergency AC repair.
    • AC making strange noise. Screeching, banging or clicking sounds coming from your AC could indicate a serious problem. If you’re noticing unusual air conditioner noises, shut off your AC and call A-Plus Service Experts for prompt AC repair at 301-747-3140.
  • Most companies will recommend an AC replacement when the price to repair your system is more than half the cost of a new system. For more factors to consider, visit our blog covering more details on whether to repair or replace your AC.

  • We service and install all types, including central AC, ductless mini-splits and central heat pumps. (Conditional content: As an effort to promote sustainability practices, we also install geothermal and solar HVAC.)

  • Heat pumps differ from other HVAC equipment because they move heat in or out of the building rather than creating it. The flow of heat can be reversed, allowing heat pumps to provide both heating and cooling.

  • For best results, have your heat pump maintained at least once a year. This will help prolong the system’s life span and help to reduce repair and utility costs.

  • Maintaining energy-efficient equipment helps bring costs down. Explore our helpful in-depth information about keeping your systems healthy. This will tell you about proper maintenance and a few key benefits.

  • Yes. Professional service is just a short ways away, whether you’re in need of a heat pump repair or replacement on a weekend day or in the middle of the night. Give us a call at 301-747-3140 for prompt service.

  • Heat pumps can provide both heating and cooling, and air-source heat pumps tend to be ideal in moderate climates where temps don’t dip below 10 degrees Fahrenheit.

  • A heat pump system can replace a heating system in areas where the climate is moderate. Check our more in-depth guide on different heat pump uses in the U.S. Generally, the answer is yes. Because heat pumps transfer hot air rather than making it from a fuel source, they provide more efficiency than furnaces in most cases, and homeowners can expect 30-40% savings on utility expenses when switching.

  • This depends on varying issues that are leading to the need for repairs, which our ACE-certified technicians can help determine.

  • We install all different types of heat pumps systems, including air-source heat pumps that utilize central ductwork, ductless mini-split systems and ground-source heat pumps–also known as geothermal heat pumps).

  • Heat pump maintenance is important for the system to perform effectively and have a long life span. A heat pump should go through routine maintenance at least once a year. Trust the Experts to handle this with a maintenance membership.

  • Your home’s air filter needs to be changed on a regular basis, which is typically every 30 to 60 days.

  • Seasonal maintenance plans are worth the investment for several reasons. Constant maintenance keeps everything working as seamlessly as possible, which helps lower energy bills while extending your equipment’s life span.

  • HVAC tune-ups can often be covered in most cases under a labor warranty if your system is still under warranty, but we can check to see if tune-ups are covered. Through the Advantage Program™, key services such as heat pump maintenance are included! It’s one of the most valuable HVAC plans around.

  • Many customers pay between $250 and $600 for a heat pump repair, but this is based on what the issue is when the HVAC technician comes out to diagnose the issue.

  • Heat pumps have a slightly shorter life span than furnaces do as they’re used all year, but with adequate, many heat pump systems last about 10-15 years.

  • Yes. Our Experts are just a short drive away to assist with a heat pump repair or replacement during an emergency.

  • Packaged HVAC units are all-in-one HVAC systems that house an air handler and unit parts in one metal cabinet system. This is used to maximize space in a basement or garage, or on rooftops in multifamily buildings.

  • We install all types of packaged HVAC systems, including packaged air conditioners, packaged gas/electric systems, packaged heat pumps and duel-fueled packaged systems. Give A-Plus Service Experts a call to find the right one for your home.

Alternative Energy

  • Green energy HVAC focuses on reducing energy consumption and increasing the efficiency of existing HVAC systems in homes not set up for renewable energy options. Properly sized green installations reduce waste and increase output.

  • Some of the most energy-efficient HVAC systems available now are geothermal heat pumps and solar HVAC systems. Call 301-747-3140 today to have a conversation about system replacement if you’re interested.

  • High-efficiency HVAC systems use less energy than a standard HVAC system while providing the same (or better) output. This can save energy and money, and with regular tune-ups and maintenance, the life span of your system can increase. The longer a system is performing efficiently, the better impact we can have for sustainability.

  • There are rebates and incentive programs for certain new system installations in 2023. A-Plus Service Experts can help you navigate discounts and payment for system replacements. We also offer payment options like financing as well as HVAC lease options with our Advantage Program™.

  • Geothermal systems use energy from below ground to provide heating and cooling. They use a “loop” system by moving and delivering from either the ground or a water source in heating mode. In cooling mode, this process works in reverse by extracting heat from inside the home to the ground or a water source. The cold air in cooling mode is the result of the process of removing heat and humidity as air is recirculated.

  • Geothermal HVAC can end up saving money long term due to smaller utility bills, despite the large initial cost for installation. And they’re more efficient than traditional central heating and cooling systems. You can even secure rebates, tax credits and other federal incentives to lower costs for the installation process.

  • Like other heat pumps, geothermal models don’t generate heat but rely on the Earth’s natural ambient temperature for heating and cooling. You end up saving a lot of money on monthly utility bills, and geothermal systems are also usually more resilient. If you keep up with routine maintenance, you can get 20 years from a geothermal heat pump and as much as 50+ years for an underground loop system.

  • Yes! Geothermal heat pumps are similar to traditional central heat pumps in that they are 2-in-1 systems capable of providing both heating and cooling. Despite a confusing name, geothermal heat pumps are just as effective at cooling homes in many different climates. In fact, they’re often the most efficient type of system available!

  • Solar technology converts sunlight to electrical energy through either PV (photovoltaic) panels or with mirrors designed to focus solar radiation. PV is used in solar panels, which are the most popular solar energy system. The energy from the sunlight is absorbed by PV cells, which energizes the cells’ electrons and produces electrical energy. When paired with battery storage, the process can even generate backup power for use at night and through utility outages.

  • Pros:

    • Renewable energy source
    • Smaller energy bills
    • Fewer maintenance requirements
    • Incentive programs like state and federal tax credits

    Cons:

    • Upfront installation costs
    • Less sun lowers efficiency, making climate/region a factor
  • Solar energy systems can be a significant investment, but much of these initial costs are recoverable once the equipment has been running for a few years. Batteries without panels can range from $12,000 to $22,000 depending on energy storage capacity, while a full install with PV panels can run as much as $35,000. Schedule a quote with our Experts to find out what you need for a solar energy system.

  • Solar energy can be used for solar HVAC systems along with other appropriate equipment such as solar-powered water heaters.

  • The effectiveness of installing solar panels for your home depends on the weather and climate of where you live. Feel free to give us a call to schedule a quote and start talking about solar energy installation.

  • Our solar Experts can assist in providing information. It’s worthwhile to research if there are other programs in your state aside from the 30% federal tax credit. Finally, it’s best to have a trusted company like A-Plus Service Experts complete a home energy audit. A thorough audit helps you determine how much you can save through solar panel installation once you consider existing utility costs.

  • Sustainable HVAC design is providing HVAC systems to homeowners and building owners while focusing on high-efficiency systems, achieving higher performance, while decreasing consumption and energy loss.

  • The most common sustainable HVAC systems are geothermal heat pumps, also known as ground source heat pumps or water source heat pumps.

  • High-efficiency HVAC systems reach high performance (heating and cooling output) while consuming less energy than what was needed from older, less efficient models.

  • Green HVAC installation focuses on adding energy-efficient HVAC models and properly sizing systems for the home’s requirements to ensure a high level of comfort and efficient energy use.

  • Geothermal and solar HVAC are the most up-to-date sustainable HVAC developments in heating and cooling.

  • Scheduling frequent tune-ups on your HVAC systems can help extend your system’s life span, which is a big step for personal sustainability. Smart thermostats also control the daily temperature of your home and help with zoning, which reduces impact on your systems by not having major temperature changes. Using energy-efficient HVAC systems can also be a big step in making your HVAC eco-friendly. High-efficiency HVAC systems are usually ENERGY STAR certified, which lowers carbon emissions by reaching high performance for less energy.

  • There are rebates and incentives in 2023 for adding energy-efficient HVAC models, like high-efficiency heat pumps. The Department of Energy goes over HVAC efficiency standards and changes the minimum efficiency ratings on models, like SEER rating, AFUE rating and HSPF rating, based on the newest research. This requires manufacturers to match the minimum efficiency ratings in all new models.

Ductwork and Insulation

  • Popping sounds are common if there’s a flaw or damage in your ductwork. The actual sounds appear when there’s more airflow than your ductwork can handle. Trouble with your ductwork can lead to other ventilation and air quality concerns, such as:

    • Continual or unpleasant noise
    • Greater energy waste
    • Premature equipment failure
    • Inconsistent heating and cooling
    • Damage to the AC’s compressor
    • Overheating
    • Mold and mildew development
  • A whole-home zoning system helps you adjust where heating and cooling is focused. With supplemental thermostats and dampers installed in the ductwork, each zone’s temperature can be individually controlled.

  • The concentration of indoor pollutants average 3-5 times higher than outdoor air. In fact, EPA studies have found that exposure to contaminants can be 100 times higher indoors compared to outdoors. Allergens, microorganisms and even household cleaners can contribute to contamination and lower your indoor air quality. You can receive a comprehensive Home Health® Report Card by contacting the air quality specialists at A-Plus Service Experts.

Electrical Services

  • A licensed electrician can provide an electrical load calculation to determine the right size of service needed for a home or business. This calculation considers the electrical needs of appliances, lighting, and other electrical devices.

  • A few safety precautions include turning off the power supply before performing work on any electrical component, using insulated tools, wearing appropriate personal protective equipment (PPE) and following electrical codes and legal guidelines.

  • It’s strongly recommended that electrical service be inspected at the least every 10 years to verify that it is safe and up to code.

  • Signs of electrical service issues include flickering lights, frequent circuit breaker trips, hot or discolored electrical outlets or switches, buzzing sounds from outlets or switches and burning smells. Another issue is improper outlets in the kitchen or bathroom – which should be GFCI (ground fault circuit interrupter) outlets. This is a shock-resistant outlet that provides a safety measure and helps avoid fire hazards since water is a great conductor of electricity.

  • Efficiency may be improved through using energy-efficient appliances and light bulbs, adding insulation to walls and attics and sealing air leaks.

Indoor Air Quality

  • Indoor air quality refers to pollution in your Waldorf home or business. The concentration of airborne pollutants can be 2–5 times greater than outdoors. Since most people spend so much of their time inside and breathe roughly 3,000 gallons of air daily (according to the American Lung Association), this can eventually lead to problems.

    Depending on your specific air quality concerns, solutions include:

  • Some of the most prevalent sources of pollutants include Volatile Organic Chemicals (VOCs) such as cleaning or personal care products, fuel-burning utilities and kitchen appliances, and particulate matter like dust, pollen and smoke.

  • Definitely. Pollutants and particulate matter can promote illnesses and worsen respiratory conditions, primarily for children and the elderly. For certain contaminants like CO, the effects may even be lethal.

  • Resolving indoor air quality concerns can produce a host of benefits to your health and well-being, such as:

    • Lower risk of illness
    • Fewer or less-severe asthma/allergy symptoms
    • Relieve sinus irritation or sore throats
    • Healthier, moisturized skin
  • If you find yourself cleaning every day or coughing constantly, your indoor air may not be as healthy as you would think. Based on EPA studies, indoor pollutants can reach concentrations as much as 100 times higher than the air outdoors. You can determine your indoor air quality by setting up a Home Health® Report consultation with A-Plus Service Experts.

  • Each home has differing comfort needs, especially if someone in your Waldorf home has allergies, asthma or a weak immune system. You may need a single product like an energy-efficient air filtration system, or multiple. A-Plus Service Experts can help you find the right mix of equipment.

  • No. HVAC air filters differ in quality and design, and some have exclusive features. We generally suggest using the filter your HVAC manufacturer recommends pairing with your system. All filters are assigned MERV ratings on a scale from 1–20. MERV is short for Minimum Efficiency Reporting Value and can help you identify high-efficiency filters. For most residential needs, a MERV rating of 11 or lower is appropriate.

  • The ideal schedule for cleaning or replacing your air filter depends on multiple factors, like the filter design and MERV rating as well as the current indoor air quality. For standard 1”-3” filters, most brands recommend replacement every 30-90 days. Pets, health conditions and even nearby pollution sources can encourage replacing the filter more often.

    • A 1″ pleated air filter must be replaced every 30-60 days.
    • A 2″ pleated air filter should be swapped out every 3 months.
    • A 3” pleated air filter should be changed every 120 days.
    • A 4″ pleated air filter should be exchanged every 6 months.
    • A 5” or 6″ pleated air filter ought to be replaced every 9-12 months.
  • Assuming the condition is not your body’s hydration, extremely dry air can irritate your throat and sinuses. Look at installing a whole-home humidifier if you consistently struggle with a dry, itchy throat.

  • Your HVAC system extracts moisture as it runs, producing situations where humidity levels fall out of balance. Portable humidifiers can resolve humidity concerns in a single room or small area, but a central humidifier ensures balanced humidity throughout the entire building.

  • For most people, comfortable humidity levels are between 30-60%. These levels are especially hard to maintain in the winter, as cold air does not hold onto moisture as well as warm air. What’s more, your furnace displaces moisture by generating hot, dry heat.

  • The smartest way to find an appropriate whole-house humidifier is multiplying the total square footage by the height of the ceiling. This will help determine how many gallons of water/H2O is required every hour to ensure balanced humidity.

    You should also consider your available budget, as a humidifier needs maintenance just like any other mechanical equipment.

  • It depends on the model, but whole-house humidifiers average between 1.5 to 12 gallons per day. Obviously, drier climates will use more water to keep humidity stable.

  • Scheduled preventive maintenance is often essential for lasting equipment efficiency, and your humidifier is no different. The humidifier’s reservoir should be frequently drained and cleaned to prevent mold.

  • Carbon monoxide (CO) is a colorless, odorless and tasteless gas produced by partial fuel combustionwhich, in turn is frequently caused by limited access to oxygen. Appliances relying on natural gas, charcoal, wood or kerosene are common sources of CO gas, especially if they are not running correctly or have been installed incorrectly. CO is poisonous to the body and is lethal at high levels or long exposure.

  • Initial signs such as nausea and exhaustion are often wrongly diagnosed as a result of the flu. But CO gas exposure can progress, oftentimes leading to confusion, organ damage or even death. Other symptoms include:

    • Headaches
    • Dizziness
    • Chest pain
    • Vomiting
  • Yes. Eliminating carbon monoxide should be a key concern because of the risk it poses to your health and well-being. CO gas can be discovered in any Waldorf home or commercial property, making safe ventilation and prevention strategies universally beneficial.

  • Prevention is the best place to start. A few safety precautions to take include:

    • Don’t let your car idle in the garage. Cars are a significant source of carbon monoxide poisoning, so do not leave yours going in the restricted space of a closed garage. The same is true for gas equipment such as lawn mowers or snowmobiles.
    • Don’t use ovens or grills as sources of heat. These appliances are safe when used correctly but can make carbon monoxide when used for an extended period in small spaces.
    • Never operate a gas generator indoors. The fumes will have a much harder time dissipating.
    • Have your chimney inspected by a specialist. This ensures chimneys and vents aren’t blocked and are connected appropriately.
    • Confirm gas appliances are operating correctly, especially your heater. You can ensure efficient, safe operation by booking routine furnace maintenance with A-Plus Service Experts.

    If carbon monoxide has been detected, you should immediately vacate the building and alert the fire department and utility provider. If a leak is spotted, you should then contact a trusted HVAC company for repairs.

  • Because carbon monoxide is colorless, odorless and lethal in substantial concentrations, installing carbon monoxide detectors in central locations is the best way to alert you to its presence.

    A carbon monoxide detector is similar to a smoke alarm, monitoring the air and notifying you if carbon monoxide levels are too high. If possible, you need to have at least one detector near every bedroom on all floors in your home. More detectors can be placed near the kitchen, living areas or near combustion appliances. These detectors are most effective when used in combination with our HVAC maintenance memberships, which keep your unit in good shape and may help you prevent carbon monoxide.

  • If an air freshener isn’t doing the trick, there may be microbes or contaminants nearby producing the unpleasant odor. Bacteria and mold are frequent sources, but they can be solved with the sanitation properties of a germicidal UV light. They are particularly effective against odor-producing microorganisms.

Plumbing

  • If you notice the water heater’s supply of hot water isn’t lasting as long as it should, it could be a problem with your tank water heater. The heating element will sometimes accumulate too much grime and mineral buildup.

  • A toilet that won’t stop running could be dealing with several potential problems, such as a broken flapper seal, flush valve or flapper chain. In some cases it’s the handle itself that’s causing the problem. A running toilet wastes a lot of water, so it’s important to call Expert plumbers promptly at 301-747-3140.

  • One of the most common reasons your dishwasher isn’t draining correctly is because the drain line is clogged. The line, also called a drain hose, removes water from the dishwasher tub at the end of a cycle. If the drain line is clogged, water may not be able to flow properly. Contact our certified plumbers for troubleshooting and repairs.

  • A fast response is important if you’re dealing with a burst pipe because it froze. Expert plumbers are better equipped to resolve burst pipe repairs, but there are several things you can do on your own to keep the pipes from freezing up in the first place:

    • Open kitchen and bathroom cabinet doors to permit warmer air to circulate around the plumbing. Be sure to move any harmful cleaners and household chemicals up out of the reach of children.
    • Let the cold water drip from faucets served by exposed pipes. Running water through the pipe—even at a trickle—helps prevent ice from forming and freezing.
    • Minimize changes to the thermostat and keep your home at least 50 degrees, even in situations where you’re not home.
    • Check out our full guide for dealing with frozen pipes.
  • Dump food scraps right away with cold water and leave the disposal on for about 30 seconds to minimize the risk of clogs. Everyone should also stop putting coffee grounds, eggshells, potato peels and other large food waste into the disposal, because they lead to drainage issues and bad smells.

  • Backflow and the subsequent cross connection can happen wherever your nonpotable plumbing system meets the water lines. As such, many different types of fixtures and appliances are at risk, including:

    • Sprinklers
    • Washing machines
    • Kitchen and bathroom faucets
    • Bathtubs and showers
    • Toilets
    • And more

    For commercial properties like industrial facilities, equipment such as boilers, chemical mixing tanks and laboratory equipment are vulnerable to backflow, etc.

  • Backflow preventers stop contaminants from entering the public water supply and posing a health risk to the community. Backflow prevention is vital because it helps to ensure that the municipal water supply remains safe and free of contaminants.

  • There are several types of backflow preventers, including:

    • Reduced pressure zone (RPZ) valves
    • Double check valves
    • Pressure vacuum breaker valves

    The type of backflow preventer you might need depends on your property’s plumbing system and the most common contaminants the plumbing is susceptible to. Trusted backflow prevention services should always help determine the most appropriate make and model for your needs.

  • Your home may have an RPZ or Reduced Pressure Zone. The zone’s consistent pressure serves as a backflow prevention device to prevent contaminants from flowing backward. At A-Plus Service Experts, our certified testers specialize in:

    • Annual backflow RPZ testing
    • RPZ inspections
    • Backflow prevention device installation and maintenance

    Since preventing trouble is often easier than repairing it, you should try to have your RPZ valve inspected annually as recommended.

  • Backflow preventers typically need to be tested annually to ensure that they are functioning correctly, although the ultimate maintenance needs depend on the type of backflow preventer you have and its current condition.

  • Backflow preventers are complex technical devices, meaning installation is best left to a professional with the right tools and experience. Our backflow prevention specialists will ensure that the device is installed correctly and meets all relevant regulations and standards.

  • Costs depend on several factors. You should consider the type of backflow preventer you need and the complexity of your property’s plumbing system as well as the cost of any needed parts and labor. Call today at 301-747-3140 for a free quote.

  • There are several signs that may indicate that your backflow preventer is not working correctly including:

    • Leaks
    • A large, sudden change in water pressure.
    • Unusual sounds coming from the prevention device.

    If you notice any of these signs, it is important to contact a professional backflow prevention service provider as soon as possible.

  • Without having a backflow prevention device, the backflow may contaminate your supply of potable water. This contamination could also enter the public water supply, posing a risk to the entire community. This could leave you exposed to health or legal consequences depending on the severity of the situation.

  • The regulations and codes that require backflow prevention systems vary by jurisdiction. In some areas, they are required by law for some types of plumbing systems or for plumbing designed to handle specific contaminants. A certified backflow prevention service provider can help review any applicable regulations for your plumbing system.

  • To eliminate the risk of your garbage disposal smelling, food scraps must be ground up right away with cool water. Thirty seconds is more than enough time. Avoid dumping coffee grounds, eggshells, potato peels and banana peels into your disposal, because they frequently cause drainage issues and unpleasant smells. While bleach seems like a great idea for cleaning your garbage disposal, it hardens grease as well as other food residue in your pipes, creating clogs.

    Our plumbing Experts advise using these cleaning solutions each week to keep your disposal smelling fresh:

    • Hot water and baking soda
    • Hot water and dish soap
    • Hot water and vinegar

    You can also buy garbage disposal pods or grind up citrus peels to help remove odors. If your garbage disposal still smells, you might be dealing with a leak (especially if the smell resembles a sewer). Contact us at for Expert plumbing service.

  • A clog can form in the water line as a result of mineral buildup, rust or debris. Clogs in sewer lines are usually because of grease, hair or other debris.
