Chester asks a furnace to run seven months of the year
Furnaces here run from October through April, seven months of the year. Winter nights average 30°F from December through February, so the burner is lighting and cycling most nights of the week.
Most homes in Chesterfield County heat with electricity, but a gas furnace installed here still has to meet a federal floor. Any non-weatherized gas furnace built since November 2015 must reach at least 80 percent AFUE. That's a minimum the equipment has to clear, not an upgrade.
The county has seen 9 winter storms and 138 damaging wind events over the past ten years, and across Virginia more than a fifth of households went at least 24 hours without power in 2024. A furnace installed here should be able to start back up on its own once power returns, without anyone having to relight it.

Virginia requires HVAC contractors to hold a state license.
The Board for Contractors issues the license, and it belongs to the contractor, not to any single job. That's the state's record that this contractor was tested and can be checked against a real name. Work under $1,000 falls outside that requirement, but a furnace installation runs well past that line, so this is a job that calls for a licensed contractor.
Most cities and counties also require a permit from the local building office for a furnace installation, with an inspection once the work is done. That inspection is what confirms the gas connections and venting were put together the way they should be. The license tells you who is allowed to do the work. The permit and inspection tell you the work was checked after it was done.

- What size furnace does my house need?
- It depends on your square footage, your insulation, your windows, and the layout of your home, so there's no single number that fits every house. A contractor works this out with a load calculation, not a chart based on square footage alone. Too big and it short-cycles, wearing out parts faster and leaving rooms uneven. Too small and it runs constantly all winter without keeping up. This is worth getting right since homes here need heat from October through April.
- How do I know it's time to replace my furnace?
- Watch for rising repair calls, uneven heat between rooms, and a furnace that struggles to keep up on the coldest nights. An older furnace working harder than it used to is a sign, even if it hasn't broken down yet. With winter nights here averaging 30°F from December through February, a furnace that can't recover quickly after a cold snap is telling you something. If you're calling for repairs more than once a season, replacement is worth pricing out against another repair.
- Is a high-efficiency furnace worth it?
- It depends on how long you plan to stay in the house and how much you run the furnace. Every non-weatherized gas furnace made since November 2015 has to hit at least 80 percent AFUE, so even a standard model today isn't wasteful. A high-efficiency furnace burns less gas to make the same heat, and with 7 months of heating season here that difference adds up over the years. A contractor can walk through the actual models and price the difference for your house.
