A system built for eight months of heat and two of cooling
Winter nights in Greenfield average 17°F from December through February, and homes here need heat from October through May, eight months of the year. Summer is short by comparison, just July and August, with afternoons averaging 80°F. A new system has to hold up at both ends of that range, not just on the cold nights it works hardest.
42.2% of homes here heat with fuel oil, so replacing a furnace or boiler often means replacing an oil-fired one. Whatever goes in should be sized for those 17°F nights, not a mild day. Greenfield has also seen 59 winter storms and 275 damaging wind events over the past ten years, and statewide, 10% of households went at least 24 hours without power in 2024. That's worth raising with a contractor when a home depends on the new system through a cold snap.

- When should I replace my HVAC system?
- Replace your system when it can no longer keep up, or when repairs are becoming a pattern instead of a one-time fix. Homes here need heat from October through May and cooling in July and August, so the furnace is the part doing most of the work most of the year. Fuel oil heat, common in this area, tends to show wear through more frequent repair calls before it fails completely. A contractor can look at the unit's condition and tell you whether it's worth repairing again or time to replace it.
- Should I replace my furnace and air conditioner at the same time?
- Not necessarily. It depends on the condition of each unit, not just its age. A furnace and air conditioner installed at different times can still run fine together as long as they're matched, since mismatched equipment wears out faster and runs less efficiently. Because homes here need heat for 8 months and cooling for only 2, the furnace usually carries the heavier load and tends to show wear first. A contractor can check both units and tell you whether one or both need to go.
- 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 electrical lines, and thermostat. They check that the ductwork suits the new unit, since ducts sized for old equipment do not always fit a new one correctly. Once everything is connected, they run the system through a full cycle to confirm it heats or cools the way it should before finishing the job. The exact steps depend on what's being replaced and how the house is set up, so a contractor can walk you through what your installation will involve.
