Hot Texas summers sure know how to make an air conditioner work overtime. An A/C unit that must run so much of the time is bound to encounter a problem, the most common one being a unit that is running but not cooling. So, what is a homeowner to do during the hottest months of the year if the one appliance they rely on for comfort quits working, and why does this occur in the first place?

As with all major household appliances, maintenance is key for your A/C unit. However, even the most well-maintained air conditioners can encounter a problem. Some issues are easily resolved by the homeowner, while others require the knowledge and skill of a professional. At Air Specialist, we are dedicated to making sure you can relax in comfort this summer, and we know this equipment inside and out.

Check your thermostat

One reason an A/C unit might run constantly without cooling your home could be that the thermostat is not set properly. Always check that your thermostat is set to “cool.” Also, having the fan set to “auto” instead of “on” means that it will only be blowing when trying to cool your home. Otherwise, the fan may be just circulating warm air, which nobody wants in a sweltering Houston summer!

Change your air filter

A dirty air filter or air conditioning unit could also be responsible for malfunctioning. Clogged air filters reduce your home’s air flow and make your system run less efficiently. When you combine that with the heat of summer and a unit that must work overtime, it’s no surprise that homeowners run into issues. Change your air filters regularly or invest in a maintenance package so that you can ensure your unit is always clean and functioning properly. You also may want to take the time to inspect your outdoor A/C unit for debris or dirt clogging the ventilation.

A thermostat setting and dirty air filter are easy to manage as a homeowner. However, there could always be another problem causing a unit to run but not cool your home. Turn to the professionals at Air Specialist to help with some other common problems such as refrigerant issues, clogs in your A/C unit, leaky ducts, a damaged heat pump, a frozen coil, broken fan or bad compressor.
