When your air conditioner decides to stop working, you may automatically assume you will have to pay quite a bit of money to have it fixed. Service calls are costly, but if you are at all handy around the house, you may be able to fix the device on your own. Even central air conditioning parts are relatively cheap and if you can do the labor yourself, you will save hundreds.
The first thing you need to understand is that central air conditioners have two basic separate components. The condenser and the evaporator are the two items that operate together to create the cool air in your home. The condenser is the part that is located outside the house on a slab of concrete, most likely somewhere in the back. The evaporator is the coil that is mounted above the furnace and main duct junction.
Central air conditioners are connected to the main air distribution center in a home. The motor that heats the home and services the furnace parts also works for distributing the cool air when the air conditioner is running. As the central air conditioning parts operate, hot air flows out through the return air duct in the furnace. That hot air is moved with a blower. If your air conditioner is one, but the house is not getting any cooler, the distribution system may be the problem.
No matter what type of repairs you want to attempt, make sure the power to the air conditioning system is turned off. You will need to make sure the condenser and evaporator are both off before you start working. Both of the units are sealed so you may need a professional service person to help with maintenance over the years. Even if you have someone come out and inspect everything each year, you do not have to end your maintenance there. You can make many repairs on your own and maintain the unit by keeping track of other procedures you do throughout the year in order to make it more efficient.
If the air conditioning unit itself and the central air conditioning parts seem to be in working order, you may want to check the thermostat. The thermostat helps control the temperature in the house and it tells the air conditioner and the furnace when it gets too hot or cold and needs to run. You may just need to re-calibrate the thermostat. If that does not work, you might have to replace the device completely in order to get your air conditioner back in working order. If you feel capable with wiring, you should be able to do this on your own. Make sure you find a thermostat that is compatible with your furnace and air conditioner.
