5 Reasons Why Your Air Conditioner May Not Feel Cool

When the mercury starts rising outdoors, you expect your air conditioner to keep your home cool. Your AC may be on, but the air issuing from your vents seems too hot. 

Here are the most standard reasons why this takes place and what you can do to fix it. If you need 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 supported by a 100% Satisfaction Guarantee.* 

1.Your Thermostat is Set Improperly

Look at the fan setting. If it says “on,” the fan will run even when the AC compressor isn’t going. This is okay, but your cooling costs will be more expensive if the fan is on constantly. Change the setting to “auto,” and the blower will only operate when the compressor is running. This also means the air radiating from the vents will repeatedly appear cold. 

2.Filter is Clogged

The HVAC air filter traps airborne particles that can wear out your heating and cooling system. If it ends up being too clogged, it can lower airflow. This limits how much warm air goes over the indoor evaporator coil. If the refrigerant flowing through the coil becomes too cold, it freezes, preventing the cooling cycle from occurring. To prevent this, put in a new filter every month or as recommended by the manufacturer. 

3.Not Enough Refrigerant

Refrigerant is critical for air conditioning. It changes from a low-pressure gas to a high-pressure liquid as it shifts between the indoor evaporator coil and outdoor condensing unit. If there isn’t enough refrigerant, your air conditioner will run poorly and may not generate adequate cool air. It may also lead to a frozen evaporator coil, which as previously mentioned, halts the cooling cycle fully. You’ll need assistance from an HVAC pro, like one from Service Experts Heating, Air Conditioning & Plumbing, to fix any refrigerant leaks. 

4.Condensing Unit is Blocked

The outdoor component of your AC equipment is known as a condenser. This is essentially a big heat sink that exhausts muggy air from your home. If the metal fins are covered with dirt, the condenser can’t work efficiently. Wash down the system to clear debris that builds up and shear back shrubs to make sure the condenser isn’t blocked. 

5.Condenser Fan or Compressor has Gone Bad

While you’re inspecting the condenser, ensure the huge fan on the top of the equipment is running. If the fan motor has stopped working, the condensing unit can’t break up heat properly, and your air conditioner can start blowing hot air into your home. 

Take time to hear the compressor running in the condensing unit also. This is the heart of your air conditioner, as the part lowers the temperature of the refrigerant. Then, the refrigerant can capture more humidity when it comes back into your home. If the compressor fails, you’ll likely need to get a new system and schedule air conditioning installation
