5 Reasons Why Your Air Conditioner May Not Feel Cool

When the temp starts to rise outdoors, you expect your air conditioner to keep your home cozy. Your AC may be running, but the air coming from your vents seems lukewarm. 

Here are the most standard reasons why this takes place and what you need to do to fix it. If you require air conditioning repair in the U.S., the Experts at Service Experts Heating, Air Conditioning & Plumbing can assist you. Like always, all our AC repair work is upheld by a 100% Satisfaction Guarantee.* 

1.Your Thermostat is Set Wrong

Check the fan setting. If it reads “on,” the fan will blow even when the AC compressor isn’t running. Nothing’s wrong with this, but your electricity expenses will go up if the fan operates frequently. Change the setting to “auto,” and the blower will only run when the compressor is running. This also means the air coming from the vents will consistently seem cold. 

2.Filter Need to be Changed

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

3.Insufficient 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 there isn’t enough refrigerant, your air conditioner will cool badly and may not produce enough cold air. It might also lead to a frozen evaporator coil, which as we mentioned before, stops the cooling cycle fully. You’ll need assistance from an HVAC technician, like one from Service Experts Heating, Air Conditioning & Plumbing, to fix any refrigerant issues. 

4.Condensing Unit is Dirty

The outdoor part of your AC unit is known as a condenser. This is basically a big heat sink that exhausts muggy air from your home. If the metal fins are laced with cobwebs, the condenser can’t work efficiently. Hose down the equipment to eliminate debris that accumulates and cut back grass to ensure the condenser can “breathe.” 

5.Condenser Fan or Compressor has Gone Bad

While you’re checking the condenser, verify the huge fan on the top of the system is going. If the fan motor has gone bad, the condensing unit can’t dissipate heat like it should, and your air conditioner could start circulating warm air into your house. 

Listen for the sound of the compressor working inside the condensing unit as well. This is the heart of your air conditioner, as the piece cools the refrigerant. Then, the refrigerant can capture more heat when it circulates back into your home. If the compressor goes out, you’ll likely need to buy a new system and book air conditioning installation.
