The Most Common HVAC problems

The heating, ventilation and air conditioning (HVAC) unit in your home is very important when it comes to living in comfort. Unfortunately, the HVAC unit can suffer from a variety of different issues. This can cause a lot of issues, especially on days that are either very hot or very cold. In this article I will cover some of the most common reasons that you may experience an issue with your HVAC unit.

Poor Maintenance

One of the quickest ways to encounter a problem with your HVAC unit is to not ensure that proper routine maintenance is performed. It is important that you have maintenance performed on time and as often as needed in order to ensure the optimum performance of the unit. Having an HVAC technician check the unit regularly will help keep everything functioning properly and free from any problems.

Faulty Thermostat

One issue that can cause problems with your HVAC unit is a faulty thermostat. Many people may be surprised to know that the thermostat can cause an issue with their HVAC unit. The thermostat on the unit controls how high and low the temperature can get. It also controls the timing of when the air needs to go up or down. If this is not functioning correctly, then the air in your home can be unpredictable and make your home uncomfortable. If you need a replacement thermostat, then you should contact a local hvac equipment manufacturer for a replacement thermostat.

Dirty or Broken Coils

The HVAC unit uses coils in concert with other parts in order to make your home cool. If these coils are broken, then the unit will not be able to cool the air in your home. The coils could also just be dirty and need to be cleaned. In either case, you should contact an HVAC professional to diagnose and fix any issues with the coils.

Coolant Leak

Your HVAC unit requires coolant in order to cool your home. The coolant is basically the lifeblood of the HVAC unit. If there is little to no coolant present in the system, then the air in your home will never get cool. The coolant in your HVAC unit does not evaporate. So, if your HVAC unit has little or no coolant, then there is more than likely a leak somewhere in the system. It is best to contact a professional in order to have this problem diagnosed and repaired.

Faulty Compressor

If the coolant is the lifeblood of the unit, then the compressor is the heart. The compressor pushes the coolant through the system. If your compressor is faulty, then the coolant will not be able to cool the air. This will cause no cold air to be produced from the unit.

Dirty Filters

One of the most common and overlooked reasons why your HVAC unit may not be functioning as well as it used to is the air filters. Dirty air filters allow for poor airflow through the vents. This means that there will be very little cold air to get into your home. This also causes your air conditioner to work harder than it has to and can lead to even bigger issues in the future.
