5 Reasons Why Your Air Conditioner May Not Feel Cool

When the mercury begins to rise outdoors, you rely on your air conditioner to keep your house cool. Your AC may be on, but the air issuing from your vents appears too hot. 

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

1.Your Thermostat is Set Wrong

Look at the fan setting. If it reads “on,” the fan will run even when the AC compressor isn’t going. This is okay, but your electricity expenses will increase if the fan is on all the time. 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 consistently appear cold. 

2.Filter is Dirty

The HVAC air filter catches airborne particles that can wear out your heating and cooling system. If it gets too obstructed, it can reduce airflow. This reduces how much warm air moves over the indoor evaporator coil. If the refrigerant moving through the coil becomes too chilled, it freezes, stopping the cooling cycle from happening. To avoid this, replace the filter each month or as suggested by the manufacturer. 

3.Not Enough Refrigerant

Refrigerant is critical for air conditioning. It shifts from a low-pressure gas to a high-pressure liquid as it moves between the indoor evaporator coil and outdoor condensing unit. If there isn’t enough refrigerant, your air conditioner will operate poorly and may not generate sufficient chilled air. It may also result in a frozen evaporator coil, which as we mentioned before, halts the cooling cycle completely. You’ll need assistance from an HVAC tech, like one from Service Experts Heating, Air Conditioning & Plumbing, to repair any refrigerant issues. 

4.Condensing Unit is Blocked

The outdoor part of your AC system is known as a condenser. This is basically a large heat sink that removes muggy air from your house. If the metal fins are clogged with yard debris, the condenser can’t work efficiently. Rinse down the system to clear debris that accumulates and cut back grass to make sure the condenser isn’t blocked. 

5.Condenser Fan or Compressor has Worn Out

While you’re checking the condenser, ensure the big fan at the top of the system is going. If the fan motor has gone out, the condensing unit can’t break up heat appropriately, and your air conditioner could start sending hot air into your house. 

Pay attention to the sound of the compressor working within the condensing unit also. This is what drives your air conditioner, as the part lowers the temperature of the refrigerant. Then, the refrigerant can capture more warmth when it moves back into your house. If the compressor goes out, you’ll typically need to get a new system and book air conditioning installation.
