5 Reasons Why Your Air Conditioner May Not Feel Cool

When the temp starts to rise outside your home, you rely on your air conditioner to keep your house cool. Your AC may be on, but the air issuing from your vents seems warm. 

Here are the most common reasons why this happens and what actions you can take to fix it. If you have to have air conditioning repair in the U.S., the Experts at Service Experts Heating, Air Conditioning & Plumbing can help. Like always, all our AC repair service is supported by a 100% Satisfaction Guarantee.* 

1.Your Thermostat is Set Improperly

Examine the fan setting. If it says “on,” the fan will operate even when the AC compressor isn’t running. Nothing’s wrong with this, but your utility bills will be bigger if the fan operates constantly. Switch the setting to “auto,” and the blower will only work when the compressor is running. This also means the air issuing from the vents will always appear cool. 

2.Filter is Dirty

The HVAC air filter traps airborne particles that can damage your heating and cooling units. If it becomes too clogged, it can lower airflow. This limits how much warm air goes over the indoor evaporator coil. If the refrigerant passing through the coil becomes too cool, it freezes, blocking the cooling cycle from taking place. To stop this, put in a new filter each month or as advised by the manufacturer. 

3.Not Enough Refrigerant

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 badly and may not create adequate chilled air. It might also create a frozen evaporator coil, which as we already mentioned, halts the cooling cycle fully. You’ll need assistance from an HVAC technician, like one from Service Experts Heating, Air Conditioning & Plumbing, to repair any refrigerant problems. 

4.Condensing Unit is Blocked

The outdoor component of your AC unit is referred to as a condenser. This is basically a big heat sink that exhausts warm air from your home. If the metal fins are laced with cobwebs, the condenser can’t work efficiently. Hose down the system to remove debris that builds up and cut back vegetation to ensure the condenser isn’t obstructed. 

5.Condenser Fan or Compressor has Gone Out

While you’re checking the condenser, verify the big fan on the top of the system is spinning. If the fan motor has gone out, the condensing unit can’t break up heat properly, and your air conditioner can start sending warm air into your home. 

Listen for the sound of the compressor operating inside the condensing unit as well. This is what drives your air conditioner, as the piece cools the refrigerant. Then, the refrigerant can collect more warmth when it moves back into your house. If the compressor stops working, you’ll typically need to purchase a new system and book air conditioning installation
