Dempsey Energy handles everything your HVAC system needs, from emergency repairs to complete system replacements. We service all types of heating and cooling equipment, including furnaces, heat pumps, central air conditioning, and ductwork.
Our maintenance services catch small problems before they become expensive repairs. This is especially important in coastal Massachusetts, where salt air and temperature extremes can affect system performance.
When your HVAC system is blowing hot air instead of cooling, or your heating system won’t turn on, we have the diagnostic tools and experience to identify the problem quickly and fix it right the first time.
