5 Reasons Why Your Air Conditioner May Not Feel Cool

When the temp starts rising outside, you depend on your air conditioner to keep your home cool. Your AC could be operating, but the air issuing from your vents feels too hot. 

Here are the most frequent reasons why this occurs and what you can do to repair it. If you require air conditioning repair in the U.S., the Experts at Service Experts Heating, Air Conditioning & Plumbing can support you. Like always, all our AC repair service is upheld by a 100% Satisfaction Guarantee.* 

1.Your Thermostat is Set Incorrectly

Examine the fan setting. If it says “on,” the fan will run even when the AC compressor isn’t working. Nothing’s wrong with this, but your electricity bills will be bigger if the fan operates frequently. Adjust the setting to “auto,” and the blower will only run when the compressor is on. This also means the air coming from the vents will repeatedly seem chilly. 

2.Filter is Clogged

The HVAC air filter captures airborne particles that can damage your heating and cooling units. If it ends up being too obstructed, it can reduce airflow. This limits how much warm air flows over the indoor evaporator coil. If the refrigerant passing through the coil becomes too chilled, it freezes, stopping the cooling cycle from happening. To avoid this, replace the filter every month or as advised by the manufacturer. 

3.Refrigerant is Low

Refrigerant is critical 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 inefficiently and may not produce enough cold air. It may also create a frozen evaporator coil, which as we already mentioned, halts the cooling cycle completely. You’ll need aid from an HVAC tech, like one from Service Experts Heating, Air Conditioning & Plumbing, to repair any refrigerant problems. 

4.Condensing Unit is Dirty

The outdoor piece of your AC system is known as a condenser. This is basically a large heat sink that removes warm air from your house. If the metal fins are covered with cobwebs, the condenser can’t work efficiently. Hose down the unit to remove debris that accumulates and trim back shrubs to make sure the condenser isn’t blocked. 

5.Condenser Fan or Compressor has Gone Bad

While you’re examining the condenser, confirm the big fan on the top of the unit is running. If the fan motor has gone out, the condensing unit can’t exhaust heat properly, and your air conditioner may start blowing muggy air into your home. 

Take time to hear the compressor operating inside the condensing unit also. This is one of the most important parts of your air conditioner, as the component cools the refrigerant. Then, the refrigerant can trap more heat when it circulates back into your residence. If the compressor fails, you’ll typically need to purchase a new system and schedule air conditioning installation
