5 Reasons Why Your Air Conditioner May Not Feel Cool

When the temp starts to rise outside your home, you depend on your air conditioner to keep your home cool. Your AC could be running, but the air issuing from your vents seems lukewarm.

Here are the most frequent reasons why this happens and what you need to do about it. If you have to have air conditioning repair in Raleigh, the Experts at Service Experts Heating & Air Conditioning can help. Like always, all our AC repair work is backed by a 100% Satisfaction Guarantee.*

1.Your Thermostat is Set Incorrectly

Look at the fan setting. If it reads “on,” the fan will run even when the AC compressor isn’t running. Nothing’s wrong with this, but your cooling expenses will increase if the fan operates all the time. Change 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 seem chilly.

2.Filter Need to be Changed

The HVAC air filter captures airborne particles that can damage your heating and cooling units. If it ends up being too clogged, it can restrict airflow. This reduces how much warm air moves over the indoor evaporator coil. If the refrigerant passing through the coil becomes too cool, it freezes, preventing the cooling cycle from taking place. To stop this, replace the filter each month or as recommended by the manufacturer.

3.Not Enough 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 the refrigerant is low, your air conditioner will cool poorly and may not produce sufficient chilled air. It could also create a frozen evaporator coil, which as previously mentioned, stops the cooling cycle altogether. You’ll need help from an HVAC tech, like one from Service Experts Heating & Air Conditioning, to solve any refrigerant problems.

4.Condensing Unit is Blocked

The outdoor part of your AC unit is called a condenser. This is essentially a big heat sink that removes hot air from your home. If the metal fins are clogged with cobwebs, the condenser can’t work efficiently. Wash down the equipment to eliminate debris that builds up and cut back grass to ensure the condenser isn’t blocked.

5.Condenser Fan or Compressor has Gone Out

While you’re checking the condenser, confirm the big fan near the top of the system is running. If the fan motor has gone out, the condensing unit can’t break up heat appropriately, and your air conditioner may start circulating muggy air into your house.

Take time to hear the compressor running inside the condensing unit also. This is one of the most important parts of your air conditioner, as the piece lowers the temperature of the refrigerant. Then, the refrigerant can trap more heat when it moves back into your house. If the compressor goes out, you’ll probably need to purchase a new unit and schedule air conditioning installation.
