If you find at some point that your air conditioning unit in Concord is no longer functioning properly, there are some things you should try on your own before you spend the time to call a professional and then spend the money to have him do what you potentially could have done on your own for free. For example, if you notice that your house seems stifling even though you are sure you turned your air conditioning on, make sure that the thermostat is set to cool and has a temperature set below the current temperature of the home. Although it seems obvious, you might be surprised at how many Concord air conditioning professionals are called for this very type of thing.
First of all, a central air conditioning unit should be on a dedicated 240 volt circuit so that it is the only thing on that circuit. This little test is pretty simple to perform; just go to your fuse box and flip the breaker that is assigned to your unit. If the only thing in and out of the house that loses power is that unit, you are good to go. Check to see if there are any other tripped breakers or fuses that have blown. All you may have to do is flip a breaker to fix the problem or replace a fuse that is damaged.
Be sure that your switch on the actual furnace is turned on, and also make sure that your power switch on your Concord air conditioning unit. Again, it may sound like common sense, but apparently it is not as common as it would seem to be. Make sure that the 240 volt disconnect, which is usually right on the side of the house very near to the actual unit has not been shut off. If the power switches check out to be fine, it is then time to head indoors to check out your thermostat.
Before you do anything else though, go back to your fuse box and shut the power to the air conditioning unit off. Take the cover off and unscrew the wire from the Y terminal. Turn the power back on. While you are holding the wire (always by the insulation) touch the bare end to the R terminal for about two minutes. If the air conditioning units compressor kicks on, the problem is probably with your thermostat it might be defective, so you will need to call someone to replace it. If you touch the wires together and nothing happens, the problem probably is not with the thermostat and you will at this point have to call a professional in Concord to fix your air conditioning.
