When the mercury starts to rise outdoors, you expect your air conditioner to keep your house cool. Your AC may be on, but the air issuing from your vents feels warm.
Here are the most common reasons why this happens and what you can do about it. If you have to have air conditioning repair in Houston, the Experts at Church Services can assist you. Like always, all our AC repair service is backed by a 100% Satisfaction Guarantee.*
1.Your Thermostat is Set Improperly
Look at the fan setting. If it is switched to “on,” the fan will run even when the AC compressor isn’t working. This is okay, but your utility expenses will be more expensive if the fan operates constantly. Adjust the setting to “auto,” and the blower will only run when the compressor is running. This also means the air issuing from the vents will always appear chilly.
2.Filter is Dirty
The HVAC air filter traps airborne particles that can damage your heating and cooling equipment. If it gets too clogged, it can reduce airflow. This restricts how much warm air goes over the indoor evaporator coil. If the refrigerant passing through the coil becomes too chilled, it freezes, stopping the cooling cycle from taking place. To stop this, change the filter each month or as recommended by the manufacturer.
3.Refrigerant is Low
Refrigerant is critical for air conditioning. It changes 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 operate poorly and may not generate enough chilled air. It might also lead to a frozen evaporator coil, which as we mentioned before, prevents the cooling cycle completely. You’ll need help from an HVAC technician, like one from Church Services, to solve any refrigerant issues.
4.Condensing Unit Need to be Cleaned
The outdoor part of your AC equipment is known as a condenser. This is essentially a large heat sink that transfers humid air from your home. If the metal fins are covered with yard debris, the condenser can’t do its job. Wash down the system to eliminate built-up debris and cut back vegetation to confirm the condenser isn’t obstructed.
5.Condenser Fan or Compressor has Worn Out
While you’re examining the condenser, confirm the big fan on the top of the system is running. If the fan motor has stopped working, the condensing unit can’t dissipate heat like it should, and your air conditioner may start blowing muggy air into your house.
Take time to hear the compressor working inside the condensing unit as well. This is one of the most important parts of your air conditioner, as the piece reduces the temperature of the refrigerant. Then, the refrigerant can collect more warmth when it comes back into your house. If the compressor stops working, you’ll likely need to purchase a new air conditioner and schedule air conditioning installation.
