Improving Your Efficiency
Change your air filter regularly
You should check your air filter every month, particularly during peak winter and summer months and change your filter at least every three months for optimal service. Dirty filters make your system work harder and waste energy.
Check your HVAC equipment annually
Much like your car needs annual maintenance checks, so does your heating and air conditioning system.
Install a programmable thermostat
Set your thermostat at a higher temperature (during cooling season) or lower temperature (during heating season) while you are at work and then program it for a more comfortable temperature in time for your return home.
Seal your heating and cooling ducts
Seal and repair leaks in your duct system to achieve better efficiency. Have your system serviced at least twice a year by a licensed professional, in both the spring and fall.
