We all take climate control for granted these days. In winter, we expect warmth from our heating system; in summer, we demand the cool comfort of air conditioning. Most Portsmouth homeowners don’t give that a second thought—until the heating, ventilation, and air conditioning (HVAC) system breaks down and replacement decisions need to be made. Today, the majority of homes either use a conventional air conditioner (AC) and furnace combination or a heat pump. Our team at Ocean State Air Solutions is well-versed in the difference as well as the benefits of each type of system.
