When the temperature begins to rise outside your home, you rely on your air conditioner to keep your house cool. Your AC might be running, but the air coming from your vents appears lukewarm.
Here are the most common reasons why this takes place and what you can do to repair it. If you require air conditioning repair in San Antonio, the Experts at San Antonio Air Service Experts can assist you. Like always, all our AC repair service is supported by a 100% Satisfaction Guarantee.*
1.Your Thermostat is Set Wrong
Check the fan setting. If it says “on,” the fan will run even when the AC compressor isn’t running. This is okay, but your utility bills will increase if the fan operates all the time. Change the setting to “auto,” and the blower will only operate when the compressor is running. This also means the air coming from the vents will always feel cool.
2.Filter is Dirty
The HVAC air filter catches airborne particles that can damage your heating and cooling system. If it gets 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, blocking the cooling cycle from taking place. 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 shifts from a low-pressure gas to a high-pressure liquid as it moves 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 cause a frozen evaporator coil, which as we already mentioned, prevents the cooling cycle fully. You’ll need aid from an HVAC technician, like one from San Antonio Air Service Experts, to repair any refrigerant leaks.
4.Condensing Unit is Blocked
The outdoor part of your AC unit is called a condenser. This is essentially a large heat sink that transfers hot air from your home. If the metal fins are laced with dirt, the condenser can’t work efficiently. Rinse down the unit to clear debris that builds up and cut back bushes to make sure 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 exhaust heat like it should, and your air conditioner may start circulating warm air into your house.
Pay attention to the sound of 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 moves back into your residence. If the compressor fails, you’ll likely need to purchase a new air conditioner and schedule air conditioning installation.
