Nine months of heat, two of cooling, and a grid that doesn't always hold
Winter nights in Kennebec County average 13°F from December through February, and homes here need heat from September clear through May. That is nine months of the year your system has to work, most of them cold. Summer only asks for cooling in July and August, when afternoons average 77°F, but a new system still has to handle both jobs well, not just the one that runs longest.
Most homes here still heat with fuel oil, and whatever replaces or joins that system has to be sized for real Maine cold, not a mild-winter average. Power matters too. More than half of Maine households went at least a day without power in 2024, and the last ten years brought 40 winter storms and 55 damaging wind events to work around. A new installation is worth planning with that in mind.

- When should I replace my HVAC system?
- Once your furnace or air conditioner is breaking down more than once a season, or the repairs keep adding up, replacement makes more sense than another fix. An older unit gets harder to find parts for and tends to run less efficiently than it used to. Homes here need heat or cooling eleven months of the year, so a system on its way out has little time to rest between seasons. Rising energy bills with no other explanation are also a sign the equipment is wearing out.
- Should I replace my furnace and air conditioner at the same time?
- If both are near the end of their life, replacing them together usually makes sense. Furnaces and air conditioners installed at the same time are matched to work together, and a mismatched pair can run less efficiently or wear out sooner than it should. That said, if one unit is failing and the other still has years left in it, there is no reason to replace the healthy one early. A contractor can look at the age and condition of both and tell you whether pairing them makes sense for your house.
- What happens during an HVAC installation?
- A contractor removes the old furnace and air conditioner, or heat pump, and sets the new equipment in place, then connects it to your ductwork, gas line or electrical circuit, and the thermostat. On the cooling side, that includes running new refrigerant lines if the old ones cannot be reused. Once everything is connected, the contractor tests the system, checks refrigerant charge and airflow, and confirms the thermostat is talking to the new equipment correctly. A job that involves new ductwork or electrical work will take longer than a straight swap of matching equipment.
