There are times when your Spring Hill central AC unit just stops working. And, sometimes the solution is as easy as simply flipping a breaker back on. These 5 common checks that just about any homeowner can make may prevent an unneeded A/C repair service call.
It happens to us all; I even get a little panicky when my air conditioning system stops working on a 90+ degree day here in Spring Hill. And I certainly have a much easier time resolving the problem, but for most of you, it certainly can be a lot more difficult at times. Hopefully, you’ll find that one of these most common AC repair checks may just help you avoid a lot of hassle:
1) Check to be sure the circuit breaker isn’t tripped
Find your homes circuit panel(s) (you may have multiple) and look at the black circuit breakers, locating anything marked "ac unit" or "indoor unit, or "air handler". You are looking for a circuit that appears to be protecting your air conditioning from power surges. You probably have a “split” system, meaning your cooling system is split with indoor and outdoor units.
If one or more circuit breakers are tripped, it may have been an isolated power surge. In this case your breakers did their job and protected your system from an electrical surge. A tripped breaker will be slightly off center with the rest of the breakers above and below it.
Gently hold the breaker with your index finger and thumb and see if it is locked firmly in place or swivels just a little. A breaker that is properly set will feel firm in its positioning and will not be easily moved. If it is tripped, simply turn it back on.
Then go to the thermostat and ensure the system and the cooling temperature is set to come on. Be prepared to wait up to 7 minutes as the system resets itself before cycling back on.
If the breaker trips again, you have a more serious problem so call for service.
2) Locate and remove the air filter
You’re central air conditioner may have multiple filters so be sure to check them all if you have more than one. Simply pull the filter(s) and checked to see if they need to be cleaned or replaced. Many times that filter can become dislodged and choke off the airflow into the system. This, in turn, can cause the system to shut down or freeze up. Be sure the filter is placed within the grill or rack properly and is properly filtering the air
3) Check to be sure you have power to your home
Yes, this happens quite often. We arrive at a no-cooling or A/C repair call only to find the home has no power. Before you call for service, check your other appliances and electrical components before making the A/C system the culprit.
4) Check the thermostat battery
Take a look at your thermostat and see if it is powered up or appears blank. If it appears to have no power, check and see if it has a battery (many do not) and replace it with a new one. Thermostat failure is the cause of a lot of A/C repair calls here in Spring Hill.
5) Check your condensation float switch
Many air conditioning systems have a protective float switch on the indoor unit that is designed to shut the system off in case the condensation drain line becomes clogged and backs up. This PVC line drains the moisture to the outside that the system is designed to remove from your interior air.
The float switch will protect your home’s interior if a backup occurs. Go to interior section of your air conditioning system and locate this PVC drain. It is usually connected to the front of the unit, near the bottom.
See if you can locate the float switch where the drain line connects to the indoor cooling unit and reset it. There should be a lever that you can lift and hold for 60 seconds to re-set the switch. Be especially careful though because if the drain line is backed up it will be full of water and it may just shut off again fairly quickly.
My advice is to then call for service and have the drain line thoroughly cleaned by an A/C repair technician.
