5 Reasons Why Your Air Conditioner May Not Feel Cool

When the mercury begins to rise outside your home, you expect your air conditioner to keep your house comfortable. Your AC might be operating, but the air coming from your vents feels warm.

Here are the most frequent reasons why this occurs and what you need to do about it. If you need air conditioning repair in Saint Charles, the Experts at Golden Seal Service Experts can assist you. Like always, all our AC repair work is backed by a 100% Satisfaction Guarantee.*

1.Your Thermostat is Set Wrong

Check the fan setting. If it says “on,” the fan will operate even when the AC compressor isn’t going. Nothing’s wrong with this, but your electricity costs will be bigger if the fan operates constantly. Switch the setting to “auto,” and the blower will only run when the compressor is on. This also means the air issuing from the vents will repeatedly feel cool.

2.Filter is Clogged

The HVAC air filter catches airborne particles that can wear out your heating and cooling system. If it ends up being too blocked, it can reduce airflow. This reduces how much warm air goes over the indoor evaporator coil. If the refrigerant flowing through the coil becomes too cool, it freezes, preventing the cooling cycle from occurring. To avoid this, put in a new filter monthly or as recommended by the manufacturer.

3.Insufficient 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 cool inefficiently and may not create sufficient chilled air. It can also cause a frozen evaporator coil, which as we already mentioned, halts the cooling cycle completely. You’ll need aid from an HVAC tech, like one from Golden Seal Service Experts, to fix any refrigerant issues.

4.Condensing Unit is Dirty

The outdoor component of your AC system is called a condenser. This is actually a big heat sink that transfers hot air from your house. If the metal fins are covered with dirt, the condenser can’t run well. Rinse down the equipment to clear accumulated debris and shear back vegetation to confirm the condenser can “breathe.”

5.Condenser Fan or Compressor has Gone Bad

While you’re examining the condenser, make sure the big fan on the top of the system is running. If the fan motor has gone bad, the condensing unit can’t dissipate heat properly, and your air conditioner may start blowing muggy air into your house.

Pay attention to the sound of the compressor operating in the condensing unit too. 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 humidity when it moves back into your residence. If the compressor fails, you’ll likely need to buy a new unit and book air conditioning installation.
