HVAC maintenance is critical if you want to keep your system running properly for as long as possible. It is recommended that you do an annual check, but twice a year is definitely better. Overlooking HVAC maintenance can result in an inefficient system that breaks down to frequently and increases your energy bills, too. 

You might wonder what would happen if you forego your air conditioning unit’s maintenance. In this post, your trusted experts in air conditioning service in Lethbridge share some of the issues that are likely to happen: 


If the compressor is leaking, the system will lose refrigerant at a rapid rate, and it will lose efficiency. This is because the leak can cause the compressor to wear out sooner than it should. The system will also be loud and inefficient when it’s running.

Loud Noises

If the air conditioning unit is vibrating a lot and making strange sounds, it may be because the fan is out of balance. Air conditioner units need to be properly balanced so that they run as efficiently as possible. The unit may also be out of balance if it has a lot of added components.

Wear and Tear

Worn-out condenser coils can cause the system to break down. If the coils are dirty, they will be unable to efficiently transfer heat from the air and water to the refrigerant. As a result, the refrigerant will not be able to cool the air or water in your home. Dirty coils can also make the air conditioner units louder when they’re running.

Insufficient Cooling

If you notice that your air conditioner is not cooling your home well enough to keep it comfortable, it probably means that there is dirt and other substances clogging the air conditioning unit’s condenser coils. You need to schedule air conditioning maintenance as soon as possible to keep your system running efficiently.

Dirty Blower and Filter

Blower motors and filters need to be cleaned regularly. If you don’t clean them, they can get clogged, and the system will not be able to provide you with the right air filtration. As a result, you will not be able to breathe clean, healthy indoor air.

Higher Energy Bills

If you neglect air conditioning maintenance, you will likely be paying more for your energy bills. This is because a poorly maintained air conditioning unit will not be able to cool your home efficiently. Your room may feel warm and stuffy, and your energy bills will be higher than they have to be.

Costly Repairs

When your air conditioner breaks down, you will need to call in a professional to repair it. You might end up having to pay a lot of money to get your system repaired if you don’t schedule maintenance or repair it when necessary. As you normally notice it has broken down after you get home from a busy day or on a weekend when you are at home.

System Failure

If you fail to schedule air conditioning maintenance or do not repair your air conditioning unit when you need to, it can break down. A failure can result in a warranty being voided, and it can cost you a lot of money to get it repaired. Most manufacturers require a homeowner to have at least one maintenance call a year on their equipment for their warranty to be valid.

You should schedule air conditioning maintenance twice a year, but you can do it more often if circumstances necessitate it.
