If your air conditioning unit has shut off and won't turn back on, and it's a newer unit that shouldn't be unable to power up, you want to call a heating and cooling professional right away. There are a lot of different things that can cause this to happen, and it's most likely an electrical complication or programming issue.

When you call an AC repair company to come to the house, be sure to get out any warranty information you may for the unit. Here are some of the things to talk with the professionals about as they begin to examine the unit.

Easy Troubleshoot Repair

The air conditioning service professional may be able to come to the house for a quick and low-cost repair. Troubleshooting the air conditioner and the thermostat may fix the issue. This will be one of the first things they might try to do. Don't try to do this on your own, it could default the warranty or cause other electrical complications to the air conditioning unit.

Electrical Complications

There are many electrical complications that could be stopping the unit from powering on to run. These would include:

• Problems with the fuse or breaker box
• Capacitor problems
• A faulty contactor
• Exterior outlet problems

The HVAC professional will look at everything to determine the source of the problem. If major electrical work needs to be done, you should evaluate the cost to have the work done with the cost to have the unit replaced. You also want to make sure the unit doesn't have electrical risks.

Sensor Replacement

The air conditioner will be signaled to shut off if it is overheating, and if there are sensors reading overheating temperatures when the unit isn't running, these will need to be replaced. This could have triggered a problem with other functions inside the unit as well.

If the warranty won't cover any of the damages or if the professionals think that the unit is unfixable and you need to replace your unit, you want to take the time to consider what is the best financial option for a new unit. You may also want to get a second opinion on what is wrong with the unit.

If you have any concerns that the unit is a risk or dangerous, make sure that it is disconnected from the home. This way you don't have to worry about the connection or it turning on unexpectedly.
