5 Reasons Why Your Air Conditioner May Not Feel Cool

When the temp starts rising outdoors, you expect your air conditioner to keep your residence cool. Your AC might be on, but the air issuing from your vents appears warm.

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

1.Your Thermostat is Set Wrong

Check the fan setting. If it reads “on,” the fan will operate even when the AC compressor isn’t running. Nothing’s wrong with this, but your energy expenses will increase if the fan runs constantly. Switch the setting to “auto,” and the blower will only run when the compressor is running. This also means the air coming from the vents will consistently feel chilly.

2.Filter is Dirty

The HVAC air filter catches airborne particles that can wear out your heating and cooling equipment. If it gets too obstructed, it can reduce airflow. This limits how much warm air goes over the indoor evaporator coil. If the refrigerant passing through the coil becomes too chilled, it freezes, stopping the cooling cycle from happening. To prevent this, change the filter monthly 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 moves between the indoor evaporator coil and outdoor condensing unit. If there isn’t enough refrigerant, your air conditioner will run badly and may not generate adequate 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, to repair any refrigerant problems.

4.Condensing Unit is Dirty

The outdoor part of your AC unit is known as a condenser. This is actually a big heat sink that exhausts hot air from your home. If the metal fins are clogged with dirt, the condenser can’t work efficiently. Rinse down the system to eliminate debris that accumulates and trim back bushes to ensure the condenser isn’t blocked.

5.Condenser Fan or Compressor has Gone Out

While you’re checking the condenser, ensure the large fan on the top of the unit is running. If the fan motor has gone out, the condensing unit can’t break up heat properly, and your air conditioner could start circulating hot air into your residence.

Take time to hear the compressor running within the condensing unit too. This is what drives your air conditioner, as the piece cools the refrigerant. Then, the refrigerant can collect more humidity when it moves back into your house. If the compressor goes out, you’ll likely need to get a new system and set air conditioning installation.
