Our Heating Story
Over 15 years of keeping Massachusetts homes comfortable — one installation at a time.
From a One-Truck Operation to Local Favorite
Dan Diprima started this company with a simple philosophy: treat every customer like they're family, and never cut corners on installation quality.
What began as a solo heating and cooling repair service has grown into a full-service HVAC company with a team of 12 technicians. But some things never changed — we still answer every call personally, we still show up on time, and we still believe that a job done right the first time is the only way to do business.
Today, we serve homeowners across Worcester County and beyond, from small furnace repairs to complete system replacements. Every job gets the same attention to detail.
