When the weather starts to heat up, one of the first things we do is rush to turn on our air conditioning unit. But when the AC isn’t working correctly, our homes can quickly become uncomfortable and unpleasant. If your AC unit is no longer cooling your home as it should, it’s time to consider an HVAC repair service.

HVAC stands for Heating, Ventilation, and Air Conditioning. An HVAC repair technician can help diagnose and repair any problems with your AC unit that may be preventing it from working properly. But why is an HVAC repair service necessary in the first place? Here are seven reasons that your AC unit needs an HVAC repair service:

1. Low Refrigerant Levels

Refrigerant is a fluid that helps cool the air within a refrigerator or air conditioner by evaporating and absorbing heat. It works by absorbing heat within a room and taking it outside, allowing the air to cool down. If the refrigerant levels are too low, the air conditioner will not be able to cool the air as efficiently as it should.

2. Dirty Filters

Dirt and debris can clog up the filters in your AC unit, making it harder for air to get through. This can reduce the cooling power of your AC, making it harder for your home to be adequately cooled.

3. Condenser Coil Issues

The condenser coil is a part of the air conditioning system in a home that helps to move heat from inside the house out. It works by taking the hot air from the house and transferring it outside through the coils. If the coil becomes dirty or clogged, it can stop the system from working efficiently and effectively, leading to poor cooling and energy inefficiency.

4. Thermostat Problems

If the thermostat is not working correctly, it can stop the air conditioner from providing the cooling it is supposed to give your home.

5. Fan Issues

The fan is vital for enabling your air conditioning system to distribute air evenly and efficiently throughout your home. If the fan is malfunctioning, it could prevent the AC from effectively cooling your space.

6. Leaky Ducts

When air ducts have holes or cracks, air escapes and make it difficult for the air conditioning unit to keep the space cool, this causes the AC system to work harder than it should, using more energy and potentially leading to premature damage to the AC unit.

7. Strange Noise

If you start to hear loud noises, such as squealing, grinding, or banging, it is time to call an HVAC repair service. These sounds can indicate such problems as worn-out fan motors, loose components, or low refrigerant levels. If you hear any of these noises, do not ignore them, as they can further damage your system.


HVAC repair services are necessary to keep your air conditioning unit running efficiently and safely. If you notice any of these signs, it is important to contact a professional HVAC repair service right away to prevent costly repairs, reduce energy costs, and improve the air quality in your home.
