5 Reasons Why Your Air Conditioner May Not Feel Cool

When the mercury begins to rise outside your home, you expect your air conditioner to keep your home cozy. Your AC may be running, 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 Birmingham, the Experts at Norrell Service Experts can support you. Like always, all our AC repair labor is supported by a 100% Satisfaction Guarantee.* 

1.Your Thermostat is Set Wrong

Examine the fan setting. If it is switched to “on,” the fan will blow even when the AC compressor isn’t running. This isn’t a problem, but your utility expenses will increase if the fan runs all the time. Adjust 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 feel chilly. 

2.Filter is Dirty

The HVAC air filter catches airborne particles that can ruin your heating and cooling equipment. If it gets too obstructed, it can reduce airflow. This restricts how much warm air moves over the indoor evaporator coil. If the refrigerant flowing through the coil becomes too cool, it freezes, preventing the cooling cycle from taking place. To stop this, put in a new filter each month or as advised by the manufacturer. 

3.Refrigerant is Low

Refrigerant is essential for air conditioning. It shifts from a low-pressure gas to a high-pressure liquid as it moves between the indoor evaporator coil and outdoor condensing unit. If refrigerant is leaking, your air conditioner will run inefficiently and may not generate adequate cold air. It could also cause a frozen evaporator coil, which as we already mentioned, halts the cooling cycle fully. You’ll need aid from an HVAC pro, like one from Norrell Service Experts, to solve any refrigerant leaks. 

4.Condensing Unit is Dirty

The outdoor part of your AC equipment is known as a condenser. This is basically a big heat sink that exhausts warm air from your home. If the metal fins are covered with dirt, the condenser can’t run well. Rinse down the unit to remove built-up debris and shear back shrubs to ensure the condenser isn’t blocked. 

5.Condenser Fan or Compressor has Gone Bad

While you’re inspecting the condenser, make sure the huge fan near the top of the system is working. If the fan motor has stopped working, the condensing unit can’t dissipate heat like it should, and your air conditioner can start blowing hot air into your residence. 

Pay attention to the sound of the compressor working within the condensing unit as well. This is what drives your air conditioner, as the component reduces the temperature of the refrigerant. Then, the refrigerant can trap more heat when it moves back into your house. If the compressor fails, you’ll likely need to purchase a new unit and book air conditioning installation
