No matter what system you’re using, you can extend the life of the equipment by following proper maintenance procedures. A few helpful hints:

  • Change your filters every three months at a minimum. It’s best to change them every 1 to 2 months. Use thinner filters in the summer.
  • Use a programmable thermostat. Remember to check the batteries occasionally, as they’ll need to be changed out. If your thermostat reads “AC,” this means you’ve had a power loss. Check to make sure your breakers are on.
  • Close the vents in rooms that aren’t being used — especially the basement vents in the summer.
  • Open the basement vents in the winter. Avoid blocking your vents with furniture or drapery; this holds particularly true with cold air vents. You should have regular inspections done, and have them cleaned every 2 to 3 years.
  • In commercial units, rooftop equipment should be maintained every few months. You should also consider having your filter changed every month, depending on the rooftop level.

Besides servicing your every need when it comes to heating and air conditioning, we also specialize in home air cleaning, sales of rebuilt appliances and tankless water heaters.
