DIY Preventative Maintenance

Its 6 p.m., a very hot 96 degrees with the humidity at about 80%, and you just got home. Of course, the a/c in your car didn’t quite have time to cool off before you got in the bumper to bumper traffic on the interstate, so you had to turn it off before the auto overheated. That’s OK. At least you remembered to leave your home a/c turned down to about 65 degrees.

You’ll cool off once inside and you shed the sweat soaked clothes. Just getting the house key in the hole makes you sweat. Then it hits you right in the face! A blast of hot air that has started your head pounding. No air conditioning!

OK, I know this has happened to at least 75% of the population. Especially if you live in the south, you know what I’m talking about. How can you prevent this from happening again? There are no absolute guarantees it won’t. No, you can’t be completely safe from this aggravating situation. But you can help your heating and cooling system just by reading your owner’s manual. I know, who reads these things? We do, the ones’ who have been in this same situation. Believe it or not, there are some good facts that you need to know to stay comfortable.

First and foremost: Learn how to operate your thermostat! I think about 10% do not know how to do this.

Second: Know where your filter is and replace it, or clean it, once a month, every 2 weeks if you have pets with hair. And I have to tell you, some people don’t even know they have filters for their units that must be cleaned or replaced some time. If this isn’t done you will have a very expensive repair bill.

Third: Locate all the electrical breakers, inside and out, to all your pieces of equipment. Some systems have electric air filters, or cleaners, or humidifiers, even other electrical components that could cause the system to stop. Know where the breakers are and how to turn them back on.

There aren’t that many parts of the system that a normal homeowner can deal with on the system. The first check point should be your thermostat. Be sure it is on, and the temperature is set at the correct temperature you want in the house. If this looks good, go to your filter and check it. If it looks like a rug, change it. If you’re not sure, change it anyway. Now give it about 15 minutes, put your hand as close to a vent in one of the rooms, and see if any cool air is coming out.

OK, so that didn’t work. Do you have any idea where the condensing unit is? It is usually somewhere along the back of the house, or on an end. Once you do find it, see if you can hear it running. Usually there is a fan close to the top which you may be able to see, hear, or feel hot air coming out the top. If this unit is not running there should be an electrical disconnect box on the wall within 3 feet of the unit. It only has one lever on the side which should say ‘ON’ and ‘OFF’.

Be sure the leaver is in the ON position. Your unit may have a delay on it which may not let it come on right away. Wait about 5 minutes, if it’s still not on you may have a problem.
You can go to your main electrical panel and be sure all breakers, at least one will be 110 v., and one will be a 230 v., going to your system, are not tripped off. Turn the breakers off and then back on kind of hard. Again, give the unit about 5 minutes. If nothing is happening, I suggest you call someone certified to work on your air conditioning system. If you are lucky enough to get the cool air on, you will have to be patient with it. Everything, walls, floors, furniture, ceilings, is at 96 + degrees. It will take a long time for everything to cool down to a tolerable temperature. It would probably be best to eat dinner out somewhere its cool. Let the unit try to catch up a little before you face that heat again.

These systems are pretty simple to operate. And after you read the maintenance and operation manual, you will be able to troubleshoot your problems, if they are minor, to keep from having another annoying and uncomfortable situation.

If you have to call a service technician to check your air conditioning, be sure he is certified and bonded. If he isn’t, find someone that is. This can save you time, money, and nerves. I was the customer service person for a fairly large heating and cooling contractor, I know what I’m talking about! There isn’t anything I haven’t heard from irate customers. Just keep your cool, read your manual, follow the directions, and hope for cooler weather.
