5 Reasons Why Your Air Conditioner May Not Feel Cool

When the mercury starts to rise outside, you rely on your air conditioner to keep your house cool. Your AC could be running, but the air coming from your vents seems warm.

Here are the most standard reasons why this occurs and what you can do about it. If you have to have air conditioning repair in Nashville, the Experts at Donelson Air Service Experts can support you. Like always, all our AC repair work is upheld by a 100% Satisfaction Guarantee.*

1.Your Thermostat is Set Incorrectly

Look at the fan setting. If it says “on,” the fan will operate even when the AC compressor isn’t working. This is okay, but your energy bills will go up if the fan operates frequently. Adjust the setting to “auto,” and the blower will only work when the compressor is on. This also means the air coming from the vents will consistently appear cold.

2.Filter is Dirty

The HVAC air filter captures airborne particles that can ruin your heating and cooling units. If it becomes too obstructed, it can restrict airflow. This restricts how much warm air moves over the indoor evaporator coil. If the refrigerant moving through the coil becomes too cool, it freezes, preventing the cooling cycle from taking place. To stop this, put in a new filter monthly or as advised by the manufacturer.

3.Not Enough Refrigerant

Refrigerant is the key to air conditioning. It transitions from a low-pressure gas to a high-pressure liquid as it moves between the indoor evaporator coil and outdoor condensing unit. If there isn’t enough refrigerant, your air conditioner will run badly and may not create sufficient cool air. It may also lead to a frozen evaporator coil, which as previously mentioned, stops the cooling cycle altogether. You’ll need help from an HVAC technician, like one from Donelson Air Service Experts, to fix any refrigerant issues.

4.Condensing Unit is Dirty

The outdoor component of your AC system is known as a condenser. This is essentially a big heat sink that transfers muggy air from your residence. If the metal fins are clogged with yard debris, the condenser can’t do its job. Hose down the unit to clear built-up debris and trim back shrubs to confirm the condenser can “breathe.”

5.Condenser Fan or Compressor has Gone Out

While you’re checking the condenser, make sure the huge fan near the top of the equipment is running. If the fan motor has gone bad, the condensing unit can’t break up heat appropriately, and your air conditioner might start sending hot air into your residence.

Pay attention to the sound of the compressor running within the condensing unit as well. This is what drives your air conditioner, as the part lowers the temperature of the refrigerant. Then, the refrigerant can capture more humidity when it moves back into your house. If the compressor stops working, you’ll typically need to buy a new system and set air conditioning installation.
