What to Do If Your Air Conditioner Stops Working


If your Lutz air conditioning stops working, there are a few things you can do before you call a professional that might fix the problem. If nothing else, this will allow you to better communicate to your technician what you feel the problem might be. Follow these steps, and if you are still unable to find the root of the air conditioner’s problem, proceed to call in a Lutz AC professional. Don’t attempt to fix electrical or other complex problems on your own.

 Check the Thermostat

Is the thermostat set properly? Check all thermostats in your home and make sure they are not only set to the right temperature but to the right cooling mode. This might sound obvious, but often a major air conditioning scare can be directly tied to a child playing with a thermostat or the system accidentally being put into heating mode.

 Check the Filters

If the air flow from your air conditioner has decreased or a line has frozen over, first turn off your air conditioner from the thermostat and then check the filters. If you clean and change them regularly, this shouldn’t be the problem, but it is always possible for the filter to get prematurely clogged. The only way to know for sure is to inspect and clean them again and see if the issue is fixed.

 Dirty Unit

Check the outdoor unit for a buildup of dirt, dust or debris. There should be no brush or debris around your system and no visible dirt or dust on the system’s exterior. If there is, turn off your air conditioner and clean the system thoroughly, removing any excess dust or debris before turning it back on. The blocked air flow can often be the root of the problem.

If these things don’t fix whatever issues you are having with your Lutz air conditioner it may be time to call Ierna’s Heating & Cooling to perform further diagnostics.
