When the temp begins to rise outdoors, you depend on your air conditioner to keep your residence cool. Your AC may be on, but the air coming from your vents appears lukewarm.
Here are the most common reasons why this occurs 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 support 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 is switched to “on,” the fan will operate even when the AC compressor isn’t working. Nothing’s wrong with this, but your energy bills will be more expensive if the fan runs frequently. 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 Dirty
The HVAC air filter captures airborne particles that can ruin your heating and cooling equipment. If it gets too blocked, it can lower airflow. This limits how much warm air goes over the indoor evaporator coil. If the refrigerant moving through the coil becomes too chilled, it freezes, preventing the cooling cycle from happening. To prevent this, change the filter monthly 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 there isn’t enough refrigerant, your air conditioner will cool badly and may not produce enough cold air. It can also create a frozen evaporator coil, which as previously mentioned, stops the cooling cycle completely. You’ll need aid from an HVAC pro, like one from Aramendia Plumbing, Heating and Air, to repair any refrigerant leaks.
4.Condensing Unit is Blocked
The outdoor component of your AC equipment is called a condenser. This is actually a large heat sink that removes humid air from your home. If the metal fins are covered with yard debris, the condenser can’t do its job. Rinse down the equipment to remove debris that accumulates and shear back vegetation to confirm 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 working. If the fan motor has gone out, the condensing unit can’t break up heat appropriately, and your air conditioner could start blowing muggy air into your house.
Pay attention to the sound of the compressor operating in the condensing unit too. This is one of the most important parts of your air conditioner, as the part lowers the temperature of the refrigerant. Then, the refrigerant can capture more humidity when it moves back into your home. If the compressor goes out, you’ll probably need to purchase a new system and book air conditioning installation.
