Below you will find some our most frequently asked questions. If you have a question that you do not see on this list, please feel free to call us or visit or Contact Us page to send us an email.

How often should I change my air filter?

Air filters should be changed every thirty days unless the system has been turned off.

What temperature should I set my thermostat at?

Average cooling set point is 78 degrees with heating set point at 70 degrees, but set your thermostat where you are most comfortable. Try not to change it in anything more than 3 degree increments.

How often should I have my system serviced by a professional?

Manufacturers require that systems be serviced twice a year in order to maintain warranties. Semi-annual service and frequent air filter changes are all you need to properly maintain your system and keep it running at peak performance.
