When the temperature begins to rise outside your home, you rely on your air conditioner to keep your house comfortable. Your AC might be running, but the air issuing from your vents appears too hot.
Here are the most common reasons why this takes place and what you can do to repair it. If you have to have air conditioning repair in San Antonio, the Experts at San Antonio Air Service Experts can support you. Like always, all our AC repair labor is supported by a 100% Satisfaction Guarantee.*
1.Your Thermostat is Set Improperly
Check the fan setting. If it says “on,” the fan will operate even when the AC compressor isn’t running. This is okay, but your energy bills will increase if the fan is on frequently. Change the setting to “auto,” and the blower will only work when the compressor is working. This also means the air coming from the vents will always feel cool.
2.Filter is Dirty
The HVAC air filter captures airborne particles that can damage your heating and cooling system. If it ends up being too blocked, it can reduce airflow. This limits how much warm air goes over the indoor evaporator coil. If the refrigerant passing through the coil becomes too cold, it freezes, stopping the cooling cycle from taking place. To stop this, put in a new filter each month or as suggested by the manufacturer.
3.Not Enough Refrigerant
Refrigerant is critical for air conditioning. It shifts from a low-pressure gas to a high-pressure liquid as it cycles between the indoor evaporator coil and outdoor condensing unit. If the refrigerant is low, your air conditioner will operate poorly and may not generate enough cool air. It may also lead to a frozen evaporator coil, which as we mentioned before, prevents the cooling cycle fully. You’ll need assistance from an HVAC pro, like one from San Antonio Air Service Experts, to repair any refrigerant leaks.
4.Condensing Unit is Blocked
The outdoor piece of your AC unit is called a condenser. This is essentially a big heat sink that transfers hot air from your home. If the metal fins are clogged with yard debris, the condenser can’t run well. Wash down the unit to clear debris that builds up and shear back bushes to confirm the condenser isn’t blocked.
5.Condenser Fan or Compressor has Gone Out
While you’re examining the condenser, verify the large fan at the top of the unit is spinning. If the fan motor has gone bad, the condensing unit can’t break up heat like it should, and your air conditioner can start circulating warm air into your house.
Take time to hear the compressor working within the condensing unit as well. This is the heart of your air conditioner, as the piece cools the refrigerant. Then, the refrigerant can trap more warmth when it comes back into your residence. If the compressor fails, you’ll typically need to purchase a new system and schedule air conditioning installation.
