5 Reasons Why Your Air Conditioner May Not Feel Cool

When the temperature begins to rise outside, you rely on your air conditioner to keep your house cool. Your AC may be on, but the air issuing from your vents feels too hot. 

Here are the most frequent reasons why this happens and what actions you can take about it. If you require air conditioning repair in Wheeling, the Experts at Comfort Masters Service Experts can assist you. Like always, all our AC repair labor is backed by a 100% Satisfaction Guarantee.* 

1.Your Thermostat is Set Wrong

Look at the fan setting. If it reads “on,” the fan will blow even when the AC compressor isn’t going. This is okay, but your electricity expenses will increase if the fan is on all the time. Change the setting to “auto,” and the blower will only work when the compressor is running. This also means the air issuing from the vents will repeatedly appear cool. 

2.Filter is Dirty

The HVAC air filter catches airborne particles that can damage your heating and cooling system. If it becomes too obstructed, it can reduce airflow. This limits how much warm air moves over the indoor evaporator coil. If the refrigerant moving through the coil becomes too chilled, it freezes, blocking the cooling cycle from happening. To avoid this, replace the filter each month or as recommended by the manufacturer. 

3.Not Enough Refrigerant

Refrigerant is critical for air conditioning. It shifts 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 operate inefficiently and may not generate enough chilled air. It may also result in a frozen evaporator coil, which as we already mentioned, halts the cooling cycle fully. You’ll need assistance from an HVAC tech, like one from Comfort Masters Service Experts, to solve any refrigerant problems. 

4.Condensing Unit is Dirty

The outdoor part of your AC system is called a condenser. This is basically a big heat sink that transfers muggy air from your house. If the metal fins are clogged with cobwebs, the condenser can’t work efficiently. Rinse down the system to clear debris that accumulates and cut back grass to ensure the condenser isn’t blocked. 

5.Condenser Fan or Compressor has Worn Out

While you’re checking the condenser, ensure the huge fan at the top of the system is going. If the fan motor has gone out, the condensing unit can’t break up heat appropriately, and your air conditioner could start sending hot air into your house. 

Pay attention to the sound of the compressor running within the condensing unit also. This is what drives your air conditioner, as the part lowers the temperature of the refrigerant. Then, the refrigerant can capture more warmth when it circulates back into your house. If the compressor fails, you’ll typically need to buy a new system and book air conditioning installation.
