Why Heat Pumps Need a Specialist

Heat pumps are more complex than a standard furnace or AC — they reverse their cycle to both heat and cool, with components a general technician may not handle every day. Caron’s technicians service heat pumps year-round across the Merrimack Valley, so we know how to diagnose them quickly and fix them right the first time.
