5 Reasons Why Your Air Conditioner May Not Feel Cool

When the mercury begins to rise outside, you rely on your air conditioner to keep your house cool. Your AC may be on, but the air issuing from your vents seems warm. 

Here are the most frequent reasons why this occurs and what you need to do about it. If you require air conditioning repair in Waldorf, the Experts at A-Plus can support you. Like always, all our AC repair work is supported by a 100% Satisfaction Guarantee.* 

1.Your Thermostat is Set Wrong

Check the fan setting. If it reads “on,” the fan will blow even when the AC compressor isn’t going. This is okay, but your electricity expenses will increase if the fan is on all the time. Adjust the setting to “auto,” and the blower will only work when the compressor is on. This also means the air issuing from the vents will consistently appear cold. 

2.Filter is Clogged

The HVAC air filter catches airborne particles that can ruin your heating and cooling system. If it gets too blocked, it can reduce airflow. This reduces how much warm air moves over the indoor evaporator coil. If the refrigerant flowing through the coil becomes too cool, it freezes, stopping the cooling cycle from happening. To avoid this, replace the filter each month or as advised by the manufacturer. 

3.Not Enough Refrigerant

Refrigerant is critical for air conditioning. It transitions from a low-pressure gas to a high-pressure liquid as it moves between the indoor evaporator coil and outdoor condensing unit. If refrigerant is leaking, your air conditioner will cool inefficiently and may not produce sufficient cool air. It may also result in a frozen evaporator coil, which as we mentioned before, halts the cooling cycle completely. You’ll need assistance from an HVAC tech, like one from A-Plus, to fix any refrigerant issues. 

4.Condensing Unit Need to be Cleaned

The outdoor part of your AC system is known as a condenser. This is basically a giant heat sink that removes muggy air from your house. If the metal fins are clogged with yard debris, the condenser can’t work efficiently. Wash down the system to clear debris that accumulates and cut back grass to make sure the condenser isn’t blocked. 

5.Condenser Fan or Compressor has Worn Out

While you’re checking the condenser, ensure the big fan at the top of the system is going. If the fan motor has gone bad, the condensing unit can’t break up heat appropriately, and your air conditioner could start sending muggy air into your house. 

Pay attention to the sound of the compressor working in the condensing unit also. This is what drives your air conditioner, as the part lowers the temperature of the refrigerant. Then, the refrigerant can capture more warmth when it comes back into your house. If the compressor stops working, you’ll typically need to get a new system and set air conditioning installation.
