Most people don’t think about their AC until it stops working. There’re few reasons behind your AC failure and if you know these reasons, you can prevent it. Here are four reasons why your air conditioner can fail.

Top 4 Reasons for AC Failure

1.    Dirty Air Filters

Air filter purifies the air by blocking all the small particles and debris. As its main function is to prevent all the dust and debris, it gets dirty very quickly. When you have a dirty air filter, the air filter won't allow the air conditioner to run at its full efficiency. Your HVAC system will have to work harder to provide heating and cooling. As a result, your HVAC system will consume more electricity, and your family won't get the desired comfort. Besides, when your HVAC system doesn't run efficiently, your HVAC system may suffer breakdowns and overheating. 

When you've got a dirty air filter, the indoor air quality of your house gets lower, and if you've allergy problems, there's a high chance that you'll suffer from allergy more often. That's why you need to change the air filter regularly. You'll have to change your air filter once every 2-3 months, depending on the usage. If you live in a polluted city, you may have to change it more frequently. It completely depends on the outside air quality. Also, you can go for a regular HVAC maintenance check to solve this problem. 

2.    Frozen Coil

A layer of frost or ice forms on the coil due to everyday use. It's a common problem in the summer. A frozen coil prevents your heating and cooling system from absorbing heat from the indoor air. As a result, your HVAC system becomes ineffective.

When you've got a frozen coil in your HVAC system, indoor air will be warmer because your HVAC system won't be able to absorb the heat from the air. It'll increase the discomfort and contradicts the main reason for using an HVAC system.

To get rid of this problem, you can call an HVAC professional to clean the frost from the coil and restore your air conditioner to the normal state.

If you notice that your air conditioner isn't providing cooling and your indoor is getting warmer, there's a high chance that your HVAC system has a frozen coil. As soon as you find this problem, you should call an expert and fix it.

3.    Faulty Fan

To remove the heat from your home space, the AC fan of your HVAC system needs to work properly. If the fan of our HVAC system doesn't work properly, heat cannot be removed from your home space. As a result, you won't get the desired cooling from your air conditioner.

4.    Refrigerant Leakage

When you run your air conditioner for a long time, the HVAC system goes under a lot of stress and pressure. This stress and strain lead to a refrigerant leak. If you don't get the desired cooling from your air conditioner, it can be because of a refrigeration leak. Refrigerant plays a key role in cooling your space. Its main duty is to absorb the heat from your space and transfer the heat outside. When the refrigerant level is low, your air conditioner won't be able to produce enough cooling. Also, you'll hear abnormal noises coming out of your HVAC system. Remember, refrigerant leak can lead to system breakdown and cost you big bucks.

There can be many reasons for the AC fan failure. It can be because of wear and tear in wires, cracks, etc. You may think that it's a small problem, but it can shut down your air conditioner. Minor problems sometimes turn into major problems and can stop your HVAC system from functioning.

To get rid of this problem, you should do a regular HVAC maintenance checkup and call an HVAC expert to look at your HVAC system.
