If you find yourself starting up your A/C unit for the first time this season and it seems that your unit has died since last fall or does not seem to be running correctly or efficiently.

Here are a few simple things that could be the cause of that issue and a few tips to keeping your unit running for the longest time possible.

We do not realize how important our HVAC systems are until it does not work. It is vital to a business or homes indoor comfort. It is inevitable if you own an HVAC system that eventually it will need an upgrade or maintenance.

The modern-day AC system is designed to last 10-20 years depending on the unit. Even the best manufacturers in the world still have issues from time to time. You just got to remember these systems are constantly running and keeping your home or workplace comfortable and humidity free.

That being said five to eight years down the road after running consistently season after season it is expected for issues to pop up, especially after an Air Conditioning unit has been shut down and not running all winter each season. The biggest tip to prevent any issues from occurring from the source is by providing regular maintenance to the unit. If you are not able to conduct this maintenance on your own it is highly recommended to hire a company to handle it for you.

It is key to remember the best way to prevent issues is simply just to be proactive and to make sure this happens. It is just like an oil change on the car you drive everyday it just has to be done.

Common Issues & causes with Air Conditioner's

Tripped Breaker-

The first thing to troubleshoot and the simplest issue to fix when determining a system that may have issues starting up is to simply check your breaker box and make sure a breaker somehow the breaker did not get tripped over time. This is a very common thing to happen in any home.

Drain Shut Off-

When your system was installed most company's offer some type of "drain pan emergency shut off switch". This is an electronic trigger that is supposed to cut your unit off if water ever starts to fill up from the unit. This saves the unit from frying itself. Like a kill switch in a boat, it can get stuck and can sometimes be the reason for a unit to not start up. So be sure to check and make sure the float did not somehow get stuck up.

Faulty Motors-

Most of the time if a unit has a faulty motor it will cause the whole system to shut down. A tech can help decide if that motor can be fixed or needs to be replaced.

Faulty Thermostats-

One possibility for issues can be the fact a thermostat is faulty or has dead batteries. One simple way of determining if this could be the cause of problems is to try turning the unit on from the main unit. If it does fire up manually that means you probably have a thermostat problem. Be sure to replace back up batteries in thermostats this could also be the cause of an issue.

Dirty Filters, Evaporators or Condenser-

By far the largest cause of problems with AC units come from dirt & dust build up overtime. Make sure you have your system serviced on a regular basis to minimize these problems. You can refer to the units manufactures filter changing schedule to maximize your unit's health and maximize the life.

Faulty Compressor-

Keeping the compressor clean can help avoid system shutdowns due to the compressor.

Shortage of Refrigerant-

If a system does not have the proper amount of refrigerant it will cause a system to operate noticeably worse and shut down in some cases. You should Always have a professional technician handle refrigerant issues, the level of these fluids and the changing of it.

Wiring Issues-

One of the leading causes of air conditioner breakdowns comes from problems with the wiring in your unit or the wiring that runs from your unit to an outlet. Be sure to check adjacent outlets and of course as stated earlier the breaker box. This allows you to ensure that the issue lies with the air conditioner and not in reaction to other electrical components.

Ice Buildup-

If a unit's condenser coils or any other part of the unit starts to build up ice the unit will not cool correctly and very possibly will not run.

  • Okay, I’m with Becky, here. Flipping my breakers off and on did the trick! I definitely expected my breakers to have flipped off if they were tripped, and they hadn’t, so I wasn’t sure this would work. But sure enough, there she blows. Thanks for the advice, and thanks to Becky for convincing me to flip my breakers off and on again! 😆👌

  • Wow ! Wow! Wow! My ac unit would not turn on. It was 90 degrees in the house. I elected to pack a bag and head to the nearest hotel to get relief until serviced. Sitting in the cold hotel room. I googled ac repair help. And this company popped up first. I read the advice #1 problem the breaker switch. I’m 10 minutes away from home. So I drove back home flipping all the breakers off and on again in the backyard. thinking to myself it ain’t no way this is gonna work. I’m really wasting my time. Walked in house and the ac was on blowing cold again. Thanks so much for sharing the repair could be’s. I was so happy , I just had to make time to write review. Even the hotel gave me a credit. Since I was only there 10 minutes.
    Feeling thankful….
