5 Reasons Why Your Air Conditioner May Not Feel Cool

When the temperature starts rising outside your home, you expect your air conditioner to keep your home cozy. Your AC could be on, but the air issuing from your vents seems lukewarm. 

Here are the most common reasons why this takes place and what you can do to fix it. If you need air conditioning repair in Edmonton, the Experts at Service Experts Heating & Air Conditioning can help. Like always, all our AC repair labour is backed by a 100% Satisfaction Guarantee.* 

1.Your Thermostat is Set Improperly

Check the fan setting. If it reads “on,” the fan will operate even when the AC compressor isn’t working. This is okay, but your utility bills will go up if the fan runs constantly. Adjust 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 feel cold. 

2.Filter Need to be Changed

The HVAC air filter traps airborne particles that can wear out your heating and cooling equipment. If it ends up being too clogged, it can lower airflow. This limits how much warm air flows over the indoor evaporator coil. If the refrigerant moving through the coil becomes too cool, it freezes, blocking the cooling cycle from happening. To avoid this, replace the filter every month or as advised by the manufacturer. 

3.Not Enough Refrigerant

Refrigerant is the key to 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 operate badly and may not produce sufficient cool air. It can also result in a frozen evaporator coil, which as we already mentioned, stops the cooling cycle completely. You’ll need aid from an HVAC professional, like one from Service Experts Heating & Air Conditioning, to solve any refrigerant issues. 

4.Condensing Unit is Dirty

The outdoor part of your AC unit is known as a condenser. This is actually a giant heat sink that removes hot air from your residence. If the metal fins are covered with yard debris, the condenser can’t do its job. Wash down the system to clear accumulated debris and trim back grass to make sure the condenser isn’t obstructed. 

5.Condenser Fan or Compressor has Gone Out

While you’re inspecting the condenser, confirm the large fan near the top of the system is going. If the fan motor has gone out, the condensing unit can’t dissipate heat appropriately, and your air conditioner may start blowing hot air into your home. 

Pay attention to the sound of the compressor operating within the condensing unit too. This is what drives your air conditioner, as the piece reduces the temperature of the refrigerant. Then, the refrigerant can collect more heat when it moves back into your residence. If the compressor stops working, you’ll probably need to buy a new unit and schedule air conditioning installation.
