A system built for nine months of heat and two of cooling
Winter nights in Waldoboro average 16°F from December through February. A new heating system has to hold steady against that cold from September through May, nine months of the year. Summer only asks two months of cooling, with afternoons averaging 75°F, but the same system needs to handle both jobs well if it's a heat pump doing double duty.
More than half of homes here still heat with fuel oil, so a new install often means deciding whether to stay with oil, switch to a heat pump, or run both together. Over half of Maine households went at least a day without power in 2024, and that's worth weighing too, since some systems start back up on their own once power returns and some don't.

- When should I replace my HVAC system?
- Replace it when repairs get frequent, when the unit is old, or when it can no longer keep the house comfortable. Parts get harder to find as a unit ages, and a contractor can tell you whether the one you have is still worth fixing. Here, homes need heat September through May, so a furnace that struggles or quits during those months is worth replacing before it fails outright. If you are calling for repairs more than once a season, have a contractor look at replacement instead of another patch.
- Should I replace my furnace and air conditioner at the same time?
- If they are close in age, yes, replacing them together usually makes sense. A furnace and air conditioner installed at the same time are matched to work with each other, and pairing an old unit with a new one can leave the new one working outside what it was built for. If one is much newer than the other, a contractor can tell you whether it is worth keeping for now. Either way, a contractor can look at both and tell you what makes sense for your house.
- What happens during an HVAC installation?
- A contractor removes the old equipment, sets the new furnace, air conditioner, or both, and connects them to the existing ductwork, gas or electrical lines, and venting. They check that the ducts and electrical setup can handle the new equipment, since a system sized wrong for the house will not heat or cool it evenly. Once it is running, they test it and walk through what it needs going forward, like filter changes. A contractor can walk you through the specifics for your house and give you a timeline before the work starts.
