What can you possibly do to fix it?
You can call in a reputable, local provider or you can try troubleshooting your AC problems with a bit of help.
Troubleshooting Your AC
Make sure that you thermostat is a on the cool setting and that it is lower than the current room temperature.
Check to see whether or not the fan is running and ask yourself, “Why is my air conditioner blowing fuses?”. If it isn’t, find out whether you have blown a fuse or tripped a circuit.
If a circuit has been tripped, you can reset this by opening up the access panel and turning the unit off and then simply turning it back on. Should it trip once more after this point, you might have a wiring issue and should speak with an HVAC professional.
Check the unit for buildups of frost or ice. The furnace may even have some water around it. Depending upon the type of unit that you own, there could be copper lines leading to the unit outside. If this is the case, you should shut the exterior unit of for a few hours and leave the blower running so that the ice melts.
If you have taken the steps mentioned above and two or so hours have passed, you can turn the exterior unit on again and allow it to run for five minutes. Once five minutes have passed, feel the copper line that is at the unit outside. If it isn’t cold or if the line has frost on it, there is a problem with the freon and you will need the help of an AC professional.
If you have tried all of these things and the unit still isn’t working, you should contact an AC company that is experienced in repairing HVAC systems.
