News & Advice


We are still fielding a lot of "NO HEAT" calls that could have been prevented with a basic "Clean & Check" preventative maintenance appointment. The furnace is cleaned and all electrical components checked for proper functionality. We can also check and replace air and humidifier filters to provide a full condition report of your furnace (or boiler).

Annual furnace maintenance would prevent over 90% of our emergency service calls for furnace repairs.

We also offer Harmonic's "Rock*Star Maintenance Program" (starting at only $15 p/mo) which includes annual Furnace and AC maintenance to eliminate surprise furnace repair issues and helps save on those emergency furnace service call fees.
