Air Conditioning FAQs
How often should my AC and furnace be serviced?
We recommend a professional tune-up once a year for each system: your air conditioner in the spring and your furnace in the fall. Our Universal Savings Agreement covers both.
Why does my air conditioner smell musty?
A musty smell usually points to moisture and mold growth in the drain pan, evaporator coil or ductwork. It should be checked by a technician.
What equipment brands do you install?
We install furnace and AC systems by American Standard and Amana. We install boilers by Dunkirk, Laars, Peerless, Burnham, Crown, Weil-McLain, Pennco, NTI, Navien and Raypak. We install ductless mini-split systems by Mitsubishi and Gree. Indoor air quality and thermostat brands include Aprilaire, Honeywell, ecobee, Air Scrubber by Aerus and iWave.

Yes. We handle emergency heating and air conditioning repairs. We do not offer 24-hour emergency service to residential customers.
Do you offer free estimates?
Yes. We offer free estimates on new system installations and replacements. We charge a diagnostic fee for a technician to diagnose what’s wrong with your unit, and will provide a quote to repair the unit. Call the office for up-to-date diagnostic fees.
