In Phoenix, air conditioning repair is never a happy thought. You can't live without the AC in the summer, but sometimes the cost of air conditioning service in Phoenix can be outrageous. Before you bring someone in, see if it's a problem you can fix yourself.
If your central air conditioning unit won't turn on, look for a problem in the following five areas: power, fan and thermostat, coolant pressure, condensate drain, and start up.
First, check the power. Often, central AC systems are put on separate circuit breakers, usually with a double switch. In the winter, people sometimes flip off this breaker so the AC isn't accidentally turned on. Make sure the breaker is flipped on. If it already is, try turning it off then on again. Believe it or not, this is one of the most common "problems" technicians have to fix.
Second, see if the fan is running. Setting it to "on" instead of "auto" should at least make the furnace fan start. If it doesn't, it means no current is reaching your furnace. Turn the thermostat down as low as it will go to see if it kicks the air on. If the thermostat is programmable, make sure it's on. If there's nothing on the display, that probably means it isn't getting any power--either because the DC line or the furnace is off.
Third, take a look at the outdoor compressor unit. Sometimes it will have a high pressure cut out, which shuts it down if the coolant pressure is too high. In the cabinet, a button will stick out near the coolant lines. Push it to reset the unit. If the button pops out again, the refrigerant level needs to be checked, and you'll need to call a technician.
Fourth, check the condensate drain or pump--the part that allows the evaporator to drain condensed water on the coils. The drain or the pump might not be working properly. Clear the drain, or plug in the pump to see if you can get it going.
Fifth, have a little patience. The compressor may take a few minutes to start up, especially if it's the first time you've turned it on all year.
If you've looked at all of these places and located a problem you can't fix or still don't know what's wrong with the unit, then it's time to pay for some professional air conditioning repair in Phoenix. After all, you don't want to damage the AC system or electrocute yourself. The upside is that you'll at least know what the problem is and can prevent their overcharging you.
