Frequently Asked Questions, Now Answered

  • Where is my air filter located?

Locations of filters vary between systems. Now would be an excellent moment to find out where your filter is if you don't already know! There is typically a removable filter access door in the return air duct next to the furnace or indoor unit. It could be in a garage, attic, utility closet, basement, or crawl space. The filter may occasionally be found inside the furnace near the blower motor, especially in older systems. A central filter grille may also be mounted on a wall or ceiling in some systems. The air filter is visible when the grille swings open. To be guided, have our HVAC services.

  • What is a two-stage furnace?

The operation of a two-stage furnace is significantly more effective than a single-stage furnace. The ideal amount of heat is delivered to effectively meet the needs of your family and house. A two-stage furnace also emits less carbon dioxide into the atmosphere and is quieter because it doesn't run continuously at full power. A variable-speed, two-stage furnace would, without a doubt, be your finest option if you're looking to buy a new gas furnace. Many are available with two-speed compressors and variable-speed air handlers for the utmost economy and comfort. To have it serviced, avail of our HVAC repair, installation, and maintenance.

  • How often should I have my system serviced?

No matter what kind of HVAC system you have, it should be checked over, cleaned, and maintained at least once a year. The heating system should ideally be inspected in the fall, and the air conditioner should ideally be checked in the spring. Oil-fired equipment should unquestionably have annual cleanings and maintenance starting each heating season. Our emergency HVAC services are always available when you need urgent help with any HVAC systems that need professional help.
