When to Avoid DIY AC Repairs?

Things are bound to go wrong whether you have an advanced or a basic air conditioning system. Maintenance can help in preventing wear and tear, but sudden problems can always occur in a flash. You should get in touch with a Bay Area HVAC professional more often than not for diagnosing the problems with your HVAC system. Hiring a professional may in fact help you save money while protecting your house from a major catastrophe.

These are a few repairs you should not do on your own:

Inconsistent Temperature in Rooms

There are many reasons that can make an air conditioner cause inconsistent cooling in the rooms. The most common reason is a dirty air filter. The air conditioner will have trouble circulating air throughout the house if the filter is too worn or dirty. It’s also possible that the vents are being blocked by furniture or something else. This will again not allow a room to be cooled. These are things you can take care on your own.

However, if inconsistent cooling is because the HVAC system is not large enough or not installed properly, then you would need the help of professionals. Your air conditioner may not be large enough to fit the house if you recently renovated it to add more space. The ducts may be incorrectly installed or come loose causing cooling issues.

Leaking Water Around the Unit

Spotting a water leak is clearly one of the easiest concerns to diagnose. In fact, water leaks make up the majority of service calls to HVAC professionals. You should use a flashlight to check the overflow pan on which the air conditioning unit is situated.

You may see holes. It’s paramount that you don’t try and fix them on your own. Instead, you call a professional to install a new overflow pan. Furthermore, make sure the unit is turned off before you check anything.

Unit Making Strange Noises

It can be challenging to diagnose strange noises coming from the AC unit unlike water leaks. All air conditioners make noises, But, there are certain sounds that are unusual and not normal. You should call an AC service professional immediately if you hear any rattling, buzzing, or hissing sound coming from the unit. You should get a professional to thoroughly investigate the unit.

Motor Has Stopped Working

It can be frustrating to have your AC unit stop working suddenly. Faulty motor is the most likely culprit. There are several different reasons for a motor to stop working.

For instance, the breakers can get too hot. This may prevent the motor from correctly working. Ice may also freeze the unit and make it difficult for the motor to spin. Calling a professional is a recommended way of knowing what has gone wrong with the system.

Why Should You Avoid DIY Repairs?

It can get tempting for homeowners to try and fix their air conditioners on their own. However, this can quickly result in dangerous and costly situations. These are a few reasons why you should not attempt to take care of major AC problems:

  • Warranty can become void if the AC is not serviced by certified professional
  • Risk of electric shock
  • Air conditioners involve complicated components
