If you’re having a problem with your AC system, try these simple troubleshooting tips.

If your AC is not cooling your home, check for open doors or windows in your home. If you find open doors or windows, close them! Cool air may be escaping through them. Next, check to see if your thermostat is on, and what temperature it’s set at. If your thermostat is turned off or set incorrectly, turn on and/or reset thermostat. Then, hold your hand in front of your indoor vents. Do you feel air, but air that hasn’t been cooled? This usually means that your indoor unit is running, but not your outdoor unit. If this is the case, you might have a frozen line between your fan and compressor. Turn off your thermostat and leave it off for 1-3 hours, if that doesn’t work, call an authorized repair person.

If you aren’t getting any airflow from your system, check to see if there is any air coming through your vent. If there isn’t, your indoor blower may not be operating. If this is the case call an authorized repair person. Prior to calling, check around your outdoor unit, if you have one. If there are any leaves, hedges or property walls butting up against it. Your system may have frozen up due to a dirty coil. Ensure your outdoor unit has 1′ of clearance all around it. Lastly, check the filters in each of your system components. If any of your filters are dirty, determine which of your filters is the problem. Consult your manual to clean or replace it. If you can’t seem to simply rectify this problem, stop and call in the pros.

If your utility bill is higher than normal and temperatures have been relatively the same as past seasons, first consider whether you have new appliances (e.g. a hot tub or pool heater) that might be using lots of power. If you do, it might not be your cooling system that is causing the increase in your power bill. Check to see if your local utility company had a recent rate increase, this too could easily be the cause. In lieu of the aforementioned, check to see that your system is cycling constantly and that your thermostat is reaching its set value. If your system is cycling constantly, and is reaching its set point, this usually means that your system’s working fine, but your local temperatures are constantly in the extreme, so your system’s working extra hard to meet that set point – a very common issue in Tampa.

Lastly, if your system is cycling constantly, but isn’t reaching its set point, contact an authorized repair person.
