Nine months of heat, and winter nights near 10 degrees
Your new system has to carry the house from September through May. That is nine months of the year, and on winter nights that average 10°F it will run long and often to keep up. A furnace or heat pump sized for this has to hold up to that kind of use without strain.
Summer here stays mild, averaging 74°F in the afternoon, so cooling is a lighter load if you add it at all. The bigger risk to a new system is the power itself. Vermont has logged 40 winter storms and 38 damaging wind events over the past ten years, and in 2024, 21% of households in the state went at least 24 hours without power. That is worth planning around when you decide how the new system runs and what keeps it going if the power drops.

Vermont has no state license for HVAC contractors.
There is no state record of who is doing this work in Lamoille County. Vermont does not test HVAC contractors, does not register them, and keeps no list of who is qualified to install a heating and cooling system. Whatever protection exists here does not come from the state.
For a job like this, the local building office is what stands behind the work. In most cities and counties, replacing a furnace, air conditioner or heat pump needs a permit before the work starts and an inspection when it is done, and that inspection is what checks the work rather than any license.

- When should I replace my HVAC system?
- Replace it when repairs start costing more than they're worth or when the system can't keep up anymore, whichever comes first. If your furnace is breaking down more than once a season, or the same part keeps failing, that's your sign. Age matters too, and a furnace here works hard, since homes in Morrisville need heat from September through May. If yours is old enough that a repair might not hold through a stretch of 10°F nights, replacing it before it fails is the safer bet.
- Should I replace my furnace and air conditioner at the same time?
- Not necessarily. What matters is whether the two share parts, like a blower or ductwork sized for both. A contractor looking at your specific system can tell you whether replacing one now and the other later makes sense, or whether doing both at once is simpler given how they're connected.
- What happens during an HVAC installation?
- A contractor removes the old equipment, sets the new furnace or heat pump in place, and connects it to your ductwork, gas line or electrical circuit, and venting. They test it, check for proper airflow, and confirm it's firing or running correctly before they leave. In most towns here, this work needs a permit from the local building office, and an inspector checks it once it's done. That inspection confirms the gas and electrical connections and venting were done right, which matters most on a system that has to run hard through nine months of heating.
