5 Reasons Why Your Air Conditioner May Not Feel Cool

When the mercury starts to rise outdoors, you depend on your air conditioner to keep your residence cool. Your AC may be operating, but the air coming from your vents appears lukewarm.

Here are the most common reasons why this takes place and what you can do to repair it. If you need air conditioning repair in San Antonio, the Experts at Aramendia Plumbing, Heating and Air can assist you. Like always, all our AC repair work 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 going. Nothing’s wrong with this, but your energy bills will be more expensive if the fan runs all the time. Change the setting to “auto,” and the blower will only operate when the compressor is running. This also means the air issuing from the vents will repeatedly feel cool.

2.Filter is Clogged

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

3.Not Enough Refrigerant

Refrigerant is essential for air conditioning. It transitions from a low-pressure gas to a high-pressure liquid as it shifts between the indoor evaporator coil and outdoor condensing unit. If refrigerant is leaking, your air conditioner will operate badly and may not produce enough cold air. It can also create a frozen evaporator coil, which as previously mentioned, stops the cooling cycle fully. You’ll need assistance from an HVAC technician, like one from Aramendia Plumbing, Heating and Air, to solve any refrigerant leaks.

4.Condensing Unit is Blocked

The outdoor component of your AC system is called a condenser. This is basically a big heat sink that transfers humid air from your home. If the metal fins are covered with yard debris, the condenser can’t do its job. Wash down the equipment to remove debris that accumulates and cut back vegetation to make sure the condenser isn’t blocked.

5.Condenser Fan or Compressor has Gone Bad

While you’re examining the condenser, ensure the large fan near the top of the unit is running. If the fan motor has stopped working, the condensing unit can’t exhaust heat appropriately, and your air conditioner could start blowing muggy air into your house.

Pay attention to the sound of the compressor operating within the condensing unit too. 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 humidity when it comes back into your home. If the compressor stops working, you’ll probably need to get a new air conditioner and book air conditioning installation.
