5 Reasons Why Your Air Conditioner May Not Feel Cool

When the mercury starts rising outside, you expect your air conditioner to keep your house cozy. Your AC might be running, but the air coming from your vents appears warm. 

Here are the most common reasons why this takes place and what you can do about it. If you have to have 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 labor is supported by a 100% Satisfaction Guarantee.* 

1.Your Thermostat is Set Improperly

Examine the fan setting. If it is switched to “on,” the fan will blow even when the AC compressor isn’t running. Nothing’s wrong with this, but your utility bills will increase if the fan operates frequently. Adjust the setting to “auto,” and the blower will only operate when the compressor is working. This also means the air radiating from the vents will consistently appear chilly. 

2.Filter Need to be Changed

The HVAC air filter catches airborne particles that can ruin your heating and cooling units. If it ends up being too clogged, it can lower airflow. This reduces how much warm air goes over the indoor evaporator coil. If the refrigerant moving through the coil becomes too cool, it freezes, preventing the cooling cycle from occurring. To stop this, change the filter each month or as advised by the manufacturer. 

3.Insufficient Refrigerant

Refrigerant is critical for air conditioning. It changes from a low-pressure gas to a high-pressure liquid as it moves between the indoor evaporator coil and outdoor condensing unit. If refrigerant is leaking, your air conditioner will cool poorly and may not produce adequate cool air. It could also lead to a frozen evaporator coil, which as we already mentioned, halts the cooling cycle altogether. You’ll need assistance from an HVAC pro, like one from Service Experts Heating, Air Conditioning & Plumbing, to repair any refrigerant leaks. 

4.Condensing Unit is Dirty

The outdoor component of your AC system is known as a condenser. This is actually a giant heat sink that transfers muggy air from your house. If the metal fins are clogged with cobwebs, the condenser can’t run well. Hose down the system to clear debris that builds up and cut back vegetation to ensure the condenser isn’t obstructed. 

5.Condenser Fan or Compressor has Worn Out

While you’re checking the condenser, ensure the huge fan on the top of the system is going. If the fan motor has stopped working, the condensing unit can’t break up heat properly, and your air conditioner could start sending warm air into your house. 

Listen for the sound of the compressor operating in the condensing unit as well. This is what drives your air conditioner, as the component reduces the temperature of the refrigerant. Then, the refrigerant can capture more humidity when it comes back into your home. If the compressor fails, you’ll probably need to get a new unit and book air conditioning installation
