Nine months of heat, one month of cooling, and long stretches without power
Winter nights in Penobscot County average 10°F from December through February. A new furnace or heat pump here has to hold a house warm against real cold, night after night, from September through May. That is nine months of the year the system has to work, not just the deep winter stretch.
Summer only asks for cooling in July, with afternoons averaging 77°F, so the system spends most of its life heating and a small part of it cooling. More than half of homes here still heat with fuel oil, so if you're switching to something else, that's the baseline you're moving away from. The county also sees a lot of weather that knocks out power, 134 winter storms and 188 damaging wind events over the last ten years, and in 2024 more than half of Maine households lost power for at least a day. Whatever you install, it's worth knowing how it behaves when the power goes out and comes back.

- When should I replace my HVAC system?
- Replace it when repairs start coming often, or when the system is old enough that another breakdown feels like a matter of time. Furnaces and air conditioners both last a couple decades under normal use, but the years add up faster on a system that runs most of the year. Heat matters here from September through May, so a furnace that's struggling going into fall is worth replacing before the cold sets in rather than after it fails on a 10°F night. If your energy bills have been climbing without a clear reason, that's often the system working harder to do the same job.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, yes, it usually makes sense to do it together. A furnace and air conditioner installed at different times often wear at different rates, but when they were installed together and are both approaching the end of their life, replacing one alone can mean opening up the system again soon after for the other. A contractor can look at the age and condition of both and tell you honestly whether it's worth pairing the work or whether one still has years left in it.
- What happens during an HVAC installation?
- A contractor removes the old equipment, sets the new furnace or air conditioner in place, and connects it to the ductwork, gas or electric lines, and venting your home already has. They'll also check the ducts themselves for leaks or damage, since a new unit pushing air through bad ductwork won't perform the way it should. Once everything is connected, the system gets tested and the settings adjusted for your home before the job is called done.
