5 Reasons Why Your Air Conditioner May Not Feel Cool

When the temperature starts rising outside your home, you depend on your air conditioner to keep your residence cozy. Your AC might be running, but the air coming from your vents seems lukewarm. 

Here are the most common reasons why this occurs and what you need to do about it. If you require air conditioning repair in Edmonton, the Experts at McKinley Heating Service Experts can help. Like always, all our AC repair labour is supported by a 100% Satisfaction Guarantee.* 

1.Your Thermostat is Set Wrong

Examine the fan setting. If it reads “on,” the fan will operate even when the AC compressor isn’t running. This is okay, but your energy costs will go up if the fan operates all the time. 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 appear cold. 

2.Filter Need to be Changed

The HVAC air filter captures airborne particles that can wear out your heating and cooling units. If it gets too clogged, it can lower airflow. This reduces how much warm air moves over the indoor evaporator coil. If the refrigerant flowing through the coil becomes too cold, it freezes, blocking the cooling cycle from taking place. To stop this, replace the filter each month or as recommended by the manufacturer. 

3.Refrigerant is Low

Refrigerant is critical for air conditioning. It transitions from a low-pressure gas to a high-pressure liquid as it moves between the indoor evaporator coil and outdoor condensing unit. If the refrigerant is low, your air conditioner will operate badly and may not produce adequate cool air. It might also lead to a frozen evaporator coil, which as we mentioned before, halts the cooling cycle fully. You’ll need help from an HVAC pro, like one from McKinley Heating Service Experts, to solve any refrigerant issues. 

4.Condensing Unit Need to be Cleaned

The outdoor component of your AC system is referred to as a condenser. This is actually a big heat sink that exhausts humid air from your residence. If the metal fins are clogged with dirt, the condenser can’t do its job. Rinse down the equipment to clear built-up debris and shear back bushes to ensure the condenser can “breathe.” 

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 working. If the fan motor has stopped working, the condensing unit can’t dissipate heat like it should, and your air conditioner may start circulating muggy air into your house. 

Pay attention to the sound of the compressor running within the condensing unit as well. This is one of the most important parts of your air conditioner, as the piece lowers the temperature of the refrigerant. Then, the refrigerant can trap more humidity when it comes back into your house. If the compressor stops working, you’ll likely need to get a new air conditioner and book air conditioning installation.
