Alburgh asks a lot of a heating and cooling system
Winter nights here average 13°F from December through February, and homes need heat from September through May. That's nine months of the year the system has to hold up, so a new furnace or heat pump has to be sized for real cold, not just a mild fall evening.
Summer is short by comparison, just July and August, with afternoons averaging 78°F. Almost half the homes here heat with fuel oil, so a lot of what gets replaced is an oil furnace or boiler swapped for something else. Whatever goes in has to meet the federal minimum efficiency standard and still handle both ends of the year, the short cooling season and the long cold one.

Vermont has no state license for HVAC contractors.
There is no state license and no state registration behind the person doing this work. Nobody at the state level tested this contractor or has a file on their business. Whatever protection exists here comes from somewhere else.
For a job like this, that somewhere else is the local building office. Installing a heating and cooling system in most cities and towns needs a permit before the work starts and an inspection when it is done. That inspection is what checks the gas connections, the wiring, and the refrigerant lines against code, since the state itself will not.

- When should I replace my HVAC system?
- Once repairs start happening every year, or the system is old enough that a breakdown could leave you without heat for days, it is time to plan a replacement instead of waiting for one to force your hand. Winters here run cold, down to 13°F on average overnight from December through February, and homes need heat from September through May. That is nine months where a dead furnace is not a small problem. If a contractor tells you a repair costs a real fraction of what a new system runs, replacing it is usually the better move, especially heading into fall rather than after the first cold snap.
- Should I replace my furnace and air conditioner at the same time?
- If both are original to the house and getting old, yes, it usually makes sense to do them together. A furnace and air conditioner installed at the same time are matched to work as one system, and pairing an old furnace with a new AC, or the other way around, can mean the newer unit never runs at its best. Summers here are short, just July and August, but heat is needed nine months a year, so the furnace side of that decision carries more weight. A contractor can look at the age and condition of each unit and tell you whether replacing one now and the other later makes sense for your house.
- What happens during an HVAC installation?
- A contractor removes the old furnace, air conditioner or heat pump, sets the new equipment in place, and connects it to the ductwork, gas or electric line, and condensate drain. Once it is running, they test it, check refrigerant charge and airflow, and walk through what the thermostat does. Most cities and counties require a permit for this work along with an inspection once it is finished, so expect that step as part of the process. Given how often storms here knock out power, it is worth asking the contractor how the new system restarts on its own once power comes back, since most do without anyone needing to touch it.
