5 Reasons Why Your Air Conditioner May Not Feel Cool

When the temperature begins to rise outdoors, you expect your air conditioner to keep your house cool. Your AC could be operating, but the air blowing from your vents seems warm.

Here are the most common reasons why this happens and what you can do to repair it. If you have to have air conditioning repair in Columbus, the Experts at Service Experts Heating & Air Conditioning can support you. Like always, all our AC repair service is supported by a 100% Satisfaction Guarantee.*

1.Your Thermostat is Set Wrong

Examine the fan setting. If it says “on,” the fan will blow even when the AC compressor isn’t running. This isn’t a problem, but your utility bills will be bigger if the fan operates all the time. Switch the setting to “auto,” and the blower will only run when the compressor is on. This also means the air radiating from the vents will consistently appear cold.

2.Filter is Dirty

The HVAC air filter traps airborne particles that can wear out your heating and cooling equipment. If it gets too clogged, it can lower airflow. This limits how much warm air flows over the indoor evaporator coil. If the refrigerant passing through the coil becomes too cold, it freezes, blocking the cooling cycle from happening. To prevent this, put in a new filter every month or as suggested by the manufacturer.

3.Not Enough Refrigerant

Refrigerant is essential for air conditioning. It changes from a low-pressure gas to a high-pressure liquid as it cycles between the indoor evaporator coil and outdoor condensing unit. If refrigerant is leaking, your air conditioner will run inefficiently and may not produce adequate chilled air. It could also lead to a frozen evaporator coil, which as we mentioned before, prevents the cooling cycle fully. You’ll need aid from an HVAC technician, like one from Service Experts Heating & Air Conditioning, to fix any refrigerant problems.

4.Condensing Unit is Dirty

The outdoor component of your AC unit is referred to as a condenser. This is essentially a giant heat sink that removes hot air from your residence. If the metal fins are covered with yard debris, the condenser can’t run well. Rinse down the system to eliminate accumulated debris and trim back shrubs to make sure the condenser isn’t obstructed.

5.Condenser Fan or Compressor has Worn Out

While you’re inspecting the condenser, confirm the large fan at the top of the equipment is working. If the fan motor has gone out, the condensing unit can’t break up heat appropriately, and your air conditioner might start circulating warm air into your house.

Pay attention to the sound of the compressor running inside the condensing unit as well. This is the heart of your air conditioner, as the part lowers the temperature of the refrigerant. Then, the refrigerant can trap more warmth when it comes back into your home. If the compressor fails, you’ll probably need to buy a new unit and schedule air conditioning installation.
