5 Reasons Why Your Air Conditioner May Not Feel Cool

When the temp begins to rise outside, you rely on your air conditioner to keep your house cozy. Your AC may be running, but the air coming from your vents feels warm. 

Here are the most standard reasons why this happens and what you can do to repair it. If you require 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 upheld by a 100% Satisfaction Guarantee.* 

1.Your Thermostat is Set Improperly

Check the fan setting. If it says “on,” the fan will blow even when the AC compressor isn’t going. Nothing’s wrong with this, but your cooling bills will be bigger if the fan is on all the time. Switch the setting to “auto,” and the blower will only work when the compressor is on. This also means the air radiating from the vents will consistently feel chilly. 

2.Filter Need to be Changed

The HVAC air filter catches airborne particles that can ruin your heating and cooling units. If it gets too clogged, it can lower airflow. This reduces how much warm air flows over the indoor evaporator coil. If the refrigerant passing through the coil becomes too cold, it freezes, preventing the cooling cycle from occurring. To avoid 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 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 create enough cold air. It can also create a frozen evaporator coil, which as we already mentioned, halts the cooling cycle completely. You’ll need aid from an HVAC professional, like one from Service Experts Heating, Air Conditioning & Plumbing, to fix any refrigerant issues. 

4.Condensing Unit Need to be Cleaned

The outdoor piece of your AC system is called a condenser. This is essentially a large heat sink that exhausts humid 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 eliminate built-up debris and shear back shrubs to confirm the condenser isn’t blocked. 

5.Condenser Fan or Compressor has Worn Out

While you’re checking the condenser, verify the large fan near the top of the unit is spinning. If the fan motor has stopped working, the condensing unit can’t dissipate heat appropriately, and your air conditioner can start sending hot air into your residence. 

Listen for the sound of the compressor working inside the condensing unit as well. This is the heart of your air conditioner, as the component reduces the temperature of the refrigerant. Then, the refrigerant can collect more warmth when it comes back into your home. If the compressor goes out, you’ll typically need to get a new unit and schedule air conditioning installation
