I know it’s getting a bit cooler now, but a few short weeks ago here in Florida, we had some big air conditioning troubles at our house. And if there’s anywhere you DON’T want to have air conditioning problems, it’s definitely FLORIDA!
We tried a few different things (in our total inexperience with air conditioners) and nothing worked. We finally called a local company to come out and repair it for us.
So when Jake Hyet contacted me regarding a guest post on fixing your OWN air conditioner, I thought it was a fantastic idea! Let’s see what secrets he has for us…
When you find yourself having trouble with your air conditioning, your first thought is to call for the repairman to come out and make air conditioning repairs. However, you just might be able to identify and fix certain problems yourself and do it safely, too. Here are some steps to take to safely repair your air conditioner before you call in a repairman:
The Air Conditioner Doesn’t Turn On
1. First check to be sure that the thermostat is set to “cool.”
2. Check for a blown fuse. Normally an air conditioner operates on a dedicated 240-volt circuit. If you have in fact blown a fuse, reset the fuse. If that still doesn’t do it, then on to the next step.
3. Check if the furnace power switch is turned on, and then check the switch on the outdoor condenser as well. If that isn’t the problem, then proceed to Step 4.
4. Switch the power to the air conditioner off.
5. Remove the cover from the thermostat.
6. Unscrew the wire from the Y terminal using a screwdriver which is compatible. The terminal should be clearly labeled.
7. Hold the wire by the insulation and touch the bare end to the R terminal (which should also be clearly labeled) for a period of two minutes. If the air conditioning begins to work, it means that the thermostat is broken. If it doesn’t, then the problem is with the air conditioner itself, and you will need to call for air conditioning repairs.
Central Air Conditioning Blowing Hot Air
If you have central air which has just been added to your home and it begins to blow out hot air, the problem could be with the air conditioning installation. It could also be something as simple as the heat is on. As you were setting the thermostat, you could have flicked the switch over to “heat” instead of “cool.”
Compressor and Condenser
Head on outside and check the unit. Your compressor and condenser coils are located out here. Be certain the outside power switch is turned on to power the compressor. If it lacks power, depending on the air conditioning installation, the system might run from the inside air handler, but it will not cool. While you’re at it, check if there is debris such as leaves or other items blocking the air intakes on the system. This too can keep the air conditioner from cooling properly.
Compressor problems or leaks can lead to problems with the refrigerant that can prevent the air conditioner from blowing cool air. In this situation it’s best to leave the repairs to a professional. It could be a low refrigerant charge which can cause low cool air output or none at all and possible icing of the condenser coils on the interior of the outside unit. This type of repair is fairly inexpensive and shouldn’t hurt your wallet too much. However, if the compressor is the problem, you just might have to replace it altogether, and that can be quite an expensive repair.
Clogged Air Filter
A clogged air filter shouldn’t completely keep the air conditioner from producing cool air, but when you have a dirty air filter it can reduce the amount of cool air your system puts out and keep it from cooling properly. It only costs a few dollars to buy a new filter; unclip the old one and insert the new one by you. If you allow the filter to remain clogged, the dust circulating in the air in your home will sooner or later clog the filter and reduce its ability to cool.

Thanks, Jake! I learned some good tips today, what about you? What did you not know before reading this post! (And hey, I like that some of these tips apply to your heater, as well!)
