When the temp begins to rise outdoors, you expect your air conditioner to keep your house comfortable. Your AC may be on, but the air coming 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 support you. Like always, all our AC repair service is backed by a 100% Satisfaction Guarantee.*
1.Your Thermostat is Set Wrong
Look at the fan setting. If it reads “on,” the fan will operate even when the AC compressor isn’t working. This is okay, but your energy expenses will be more expensive if the fan operates constantly. Switch the setting to “auto,” and the blower will only run when the compressor is working. This also means the air radiating 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 ends up being too obstructed, it can lower airflow. This reduces how much warm air goes over the indoor evaporator coil. If the refrigerant passing through the coil becomes too cool, it freezes, blocking the cooling cycle from taking place. To avoid this, change the filter each month or as recommended by the manufacturer.
3.Refrigerant is Low
Refrigerant is essential for air conditioning. It shifts 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 create enough chilled air. It might also lead to a frozen evaporator coil, which as we already mentioned, prevents the cooling cycle fully. You’ll need help from an HVAC technician, like one from Church Services, to repair any refrigerant problems.
4.Condensing Unit Need to be Cleaned
The outdoor piece of your AC equipment is referred to as a condenser. This is essentially a big 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 clear debris that builds up and shear back shrubs to make sure the condenser isn’t blocked.
5.Condenser Fan or Compressor has Gone Out
While you’re examining the condenser, confirm the big fan at the top of the system is running. If the fan motor has gone out, the condensing unit can’t dissipate heat appropriately, and your air conditioner may start blowing muggy air into your residence.
Take time to hear the compressor operating inside the condensing unit as well. This is what drives your air conditioner, as the piece reduces the temperature of the refrigerant. Then, the refrigerant can collect more humidity when it moves back into your residence. If the compressor goes out, you’ll typically need to purchase a new air conditioner and schedule air conditioning installation.
