There are a few simple things that you can do before you make a service call to make your central air conditioning repair as inexpensive as possible.

These steps are the basics and any central air conditioning repair person will start here before they proceed on.  You can use these basic steps as an introduction into air conditioning repair training.

Your Central Air Conditioning Repair At Home

The first thing you want to do in your central air conditioning repair troubleshooting is make sure that everything is configured properly.  Check to make sure that the unit is receiving power and that all the dials and knobs are configured properly.

If you still have the manual for your air conditioner you can check against this, otherwise you should be able to get a copy of it online.

Once you have confirmed that all of these things are working properly, the next step in your central air conditioning repair is to confirm that the thermostat is working properly.  There should be an override on the main unit that will simply turn it on and keep it running.  If this works but the unit refuses to turn on, more then likely you have a shorted out or problematic thermostat unit.  These are inexpensive and simple to replace.

Next up on our basic central air conditioning repair guide is to check to make sure that everything is clean and the air is flowing smoothly.  The first trouble spot will be the blower fan on the air conditioning unit.  Check to make sure that the fan can spin freely and that there is not a massive build up of dirt and dust.

If there is you can clean the unit on your own and it should be a fairly easy process.  If you can clean a fan, you can clean out the blower on your air conditioning unit.

Lastly, take a look at the filter to make sure that it is not clogged up.  Many times people will overlook the filter in their central air conditioning repair, but more often then not it has not been replaced in some time and is causing serious performance issues. 

Do not attempt to clean it, simply discard it and purchase a new one.  Most filters are between ten to fifteen dollars so this step can save you hundreds.

There you have some basic steps to your central air conditioning repair.  If you take these steps you should be able to fix your air conditioner quickly and easily without an expensive bill.

Before you can relly start to do any auto air conditioning repair you need to understand a bit how your system works.  By understanding these basics you can best accomplish your auto air conditioning repair tasks.

There are many intricate components to an auto air conditioning repair job and many of these are completely unique to the auto system. What this means is that while some of the basic applications will remain the same, when looking at an auto versus a central air conditioning repair there are certain things to keep in mind.

Things To Understand Before You Begin Your Auto Air Conditioning Repair

The first thing you need to know is how the air conditioning system works and what could be going wrong with it.  At the center of the auto air conditioning repair is the compressor.  If you were to compare the system to your body the compressor would be your heart.

Taking that analogy further for your auto air conditioning repair project, the Freon is the blood of the system.  The compressor pumps Freon throughout the air conditioning system. Freon is a gas and liquid combination that is compressed and circulated through the air conditioning system. Because it is passed by pressure through different sized metal and rubber hoses the gas will expand and contract.  This process makes the Freon gas extremely cold.

Once chilled in this way the gas will make its way through metal lines to the dash of your vehicle and into the evaporator core.  An evaporator core looks like a small radiator, except that is has cold Freon inside and not hot anti freeze.

A small fan called the air conditioning blower fan sits in front of the evaporator core and blows air across this then out through the vents in your vehicle.

The other part of the air conditioning unit that you need to be aware of is the condenser side.  This part will remove heat from inside of the vehicle and also works with Freon to do this.  This part is called the Air Conditioning condenser and is located at the front of the car.

This part looks the evaporator coil and serves a similar function in that it has cold Freon going through it.  However it is designed to take heat away, not to bring cold in, a Subtle difference between the two.

As you can see there are many important components to your auto air conditioning repair job.  By understanding how all these components interact you can better troubleshoot your problems.
