Power issues
There are a couple of different reasons that can cause your air conditioner to loose power, read of to find the common solutions for when your air conditioner won't turn on.

1. Air Conditioner won’t turn on
This can seem like a complex problem that sometimes comes with a simple solution!

The first thing to check is does your air conditioner unit have power to it?

The two easy places to check for power loss include:
The breaker
The Fuse

To check your breaker, locate your electrical panel and the label for the AC unit. Check to see if the switch is in the fully "ON" position. This breaker needs to be in the on position to have power going to your air conditioning unit. If your breaker is on but do not have power to your air conditioner another common solution is to check the fuse.

Yes, your outdoor air conditioning unit comes equipped with it's own fuse. It is best to consult your air conditioning manual for the location and type of fuse that is required. If you fuse is blown, you will need to replace it before your unit will begin to function again.

If you continue to experience electrical problems and the above two suggestions to not restore power to your air conditioner, you may want to perform a visual inspection of the unit itself. Check to see if you can spot any broken, chewed, or disconnected wires especially if this is the first time you are using it for the season. If upon inspection you do notice damages, it might be best to contact your local HVAC company to come and perform a professional inspection so they can provide you with the best solution.  

Still no power? Read on, because when your air conditioner won't turn on it might be related to your thermostat.

The thermostat is responsible for telling your AC unit when to turn on and off. If it’s not working properly, your unit may not be getting the signal it needs to start up or may be turning off prematurely.

In order for a thermostat to function it requires a power source. Older model thermostats were hardwired into your homes electricity. With the advent of new digital thermostats this is not always the case, most of these modern components run on battery power. Make sure to check that the batteries are operational and if necessary replace them.

Once power is restored to your thermostat your air conditioner should be able to receive signals from the thermostat again and will turn on the unit so you can restore cooling to your home.  


Cleaning and Maintenance

6. Leaky Ducts
If your ducts are leaking, cooled air will escape before it can reach your living space. This can not only lead to an uncomfortable home environment but can also increase your energy costs.

Keep in mind that your ducts run behind your walls, through ceilings, attics and crawl spaces. You might always see where there could be a leak in your ducting system and may require professional assistance.

You air conditioning unit uses a couple of fans, one for the condenser coil to transport heat from the building to the outdoors, and the other fan is for the evaporator coil that cools the air that is then returned into your home to cool it.

A noisy air conditioner can mean a noisy fan. This can be caused by debris built up causing an obstruction to the fan, there could be worn belts that need replacing, or it could be that the bearings are starting to wear out.
