5 Reasons Why Your Air Conditioner May Not Feel Cool

When the temperature begins to rise outside your home, you expect your air conditioner to keep your house comfortable. Your AC could be running, but the air issuing from your vents seems lukewarm. 

Here are the most standard reasons why this takes place and what you can do to repair 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 backed by a 100% Satisfaction Guarantee.* 

1.Your Thermostat is Set Wrong

Examine the fan setting. If it says “on,” the fan will blow even when the AC compressor isn’t working. Nothing’s wrong with this, but your electricity costs will increase if the fan is on all the time. Change the setting to “auto,” and the blower will only operate when the compressor is running. This also means the air radiating from the vents will consistently appear cool. 

2.Filter is Dirty

The HVAC air filter traps airborne particles that can ruin your heating and cooling system. If it ends up being too clogged, it can restrict airflow. This limits how much warm air moves over the indoor evaporator coil. If the refrigerant flowing through the coil becomes too cold, it freezes, preventing the cooling cycle from happening. To prevent this, change the filter every month or as advised by the manufacturer. 

3.Not Enough Refrigerant

Refrigerant is the key to air conditioning. It transitions from a low-pressure gas to a high-pressure liquid as it cycles between the indoor evaporator coil and outdoor condensing unit. If the refrigerant is low, your air conditioner will cool badly and may not generate enough cool air. It could also lead to a frozen evaporator coil, which as we mentioned before, prevents the cooling cycle completely. You’ll need assistance from an HVAC professional, like one from Service Experts Heating, Air Conditioning & Plumbing, to fix any refrigerant issues. 

4.Condensing Unit is Dirty

The outdoor part of your AC equipment is referred to as a condenser. This is basically a big heat sink that transfers hot air from your home. If the metal fins are laced with yard debris, the condenser can’t work efficiently. Rinse down the equipment to remove debris that builds up and trim back vegetation to ensure the condenser isn’t obstructed. 

5.Condenser Fan or Compressor has Worn Out

While you’re inspecting the condenser, confirm the big fan on the top of the equipment is running. If the fan motor has gone out, the condensing unit can’t dissipate heat appropriately, and your air conditioner can start sending warm air into your house. 

Listen for the sound of the compressor operating inside the condensing unit as well. This is one of the most important parts of your air conditioner, as the piece reduces the temperature of the refrigerant. Then, the refrigerant can capture more warmth when it comes back into your house. If the compressor fails, you’ll likely need to get a new unit and schedule air conditioning installation
