5 Reasons Why Your Air Conditioner May Not Feel Cool

When the temperature starts to rise outside your home, you rely on your air conditioner to keep your home cozy. Your AC might be running, but the air coming from your vents feels warm.

Here are the most common reasons why this happens and what actions you can take about it. If you need air conditioning repair in Belleville, the Experts at D & K Heating Service Experts can help. Like always, all our AC repair service 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 running. This isn’t a problem, but your cooling costs will be more expensive if the fan runs frequently. Adjust the setting to “auto,” and the blower will only operate when the compressor is on. This also means the air issuing from the vents will always feel cold.

2.Filter is Clogged

The HVAC air filter captures airborne particles that can wear out your heating and cooling system. If it gets too obstructed, it can lower airflow. This restricts how much warm air goes over the indoor evaporator coil. If the refrigerant passing through the coil becomes too cold, it freezes, preventing the cooling cycle from occurring. To avoid this, put in a new filter monthly or as suggested by the manufacturer.

3.Not Enough Refrigerant

Refrigerant is essential 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 poorly and may not produce sufficient chilled air. It may also cause a frozen evaporator coil, which as we mentioned before, prevents the cooling cycle completely. You’ll need aid from an HVAC tech, like one from D & K Heating Service Experts, to solve any refrigerant problems.

4.Condensing Unit is Dirty

The outdoor part of your AC equipment is called a condenser. This is essentially a large heat sink that removes muggy air from your home. If the metal fins are laced with dirt, the condenser can’t work efficiently. Hose down the unit to clear debris that builds up and cut back vegetation to make sure the condenser isn’t blocked.

5.Condenser Fan or Compressor has Gone Out

While you’re checking the condenser, ensure the big fan near the top of the equipment is working. If the fan motor has gone bad, the condensing unit can’t break up heat properly, and your air conditioner might start circulating warm air into your home.

Listen for the sound of the compressor running inside the condensing unit also. 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 comes back into your house. If the compressor fails, you’ll typically need to get a new system and schedule air conditioning installation.
