5 Reasons Why Your Air Conditioner May Not Feel Cool

When the mercury starts to rise outdoors, you expect your air conditioner to keep your residence cool. Your AC could be operating, but the air issuing from your vents feels too hot. 

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

1.Your Thermostat is Set Improperly

Check the fan setting. If it reads “on,” the fan will blow even when the AC compressor isn’t working. This isn’t a problem, but your utility expenses will be bigger if the fan runs constantly. Switch the setting to “auto,” and the blower will only work when the compressor is working. This also means the air coming from the vents will always feel cold. 

2.Filter Need to be Changed

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

3.Refrigerant is Low

Refrigerant is the key to 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 refrigerant is leaking, your air conditioner will operate poorly and may not generate enough cool air. It may also create a frozen evaporator coil, which as previously mentioned, prevents the cooling cycle completely. You’ll need assistance from an HVAC tech, like one from Service Experts Heating, Air Conditioning & Plumbing, to fix any refrigerant leaks. 

4.Condensing Unit is Dirty

The outdoor piece of your AC unit is referred to as a condenser. This is actually a big heat sink that exhausts hot air from your house. If the metal fins are covered with cobwebs, the condenser can’t work efficiently. Wash down the system to eliminate debris that builds up and trim back shrubs to make sure the condenser isn’t blocked. 

5.Condenser Fan or Compressor has Gone Out

While you’re checking the condenser, verify the large fan near the top of the unit is running. If the fan motor has gone out, the condensing unit can’t dissipate heat properly, and your air conditioner may start circulating hot air into your home. 

Pay attention to the sound of the compressor working inside the condensing unit also. This is one of the most important parts of your air conditioner, as the piece reduces the temperature of the refrigerant. Then, the refrigerant can collect more warmth when it comes back into your house. If the compressor fails, you’ll probably need to buy a new air conditioner and set air conditioning installation
