A system that has to work most of the year
Stephens City needs heat eight months out of the year, October through May, with winter nights averaging 25°F. Whatever you install also has to handle summer afternoons near 84°F from June through August. Only one month sits outside one season or the other.
Half the homes here heat with electricity, which puts real load on the system through those cold months. And the power itself is not a given. Across Virginia, 22 percent of households lost power for at least 24 hours in 2024, and this area has logged 16 winter storms and 134 damaging wind events over the past ten years. A new system is worth planning around that weather, not just the day it goes in.

Virginia requires HVAC contractors to hold a state license.
The license belongs to the contractor, not the job, so it covers this installation the same as any other work they take on. Work under $1,000 falls outside this requirement, but a heating and cooling installation runs well past that line.
Most cities and counties in Virginia require a permit for a job like this, and an inspector checks the completed system before it is signed off. That permit and inspection are separate from the state license, and they cover the work itself rather than the contractor's qualifications.

- When should I replace my HVAC system?
- Look at how often you're calling for repairs, not just whether the system still runs. Once a unit is old enough that parts are failing one after another, or the last repair was something major like the compressor or heat exchanger, replacing it usually makes more sense than fixing it again. Homes here need heat or cooling 11 months out of the year, so a system that's struggling doesn't get much of a break to make it to the next season. A contractor can look at the age and repair history of your system and tell you where it stands.
- Should I replace my furnace and air conditioner at the same time?
- If they're close in age, that's usually the better time to do it. A furnace and air conditioner installed together are matched to run as one system, and putting a new unit alongside an old one can keep the new one from running the way it's rated to. If both were installed around the same time and one is failing, the other is often not far behind. A contractor can check both and tell you whether your situation calls for replacing one or both.
- What happens during an HVAC installation?
- The old furnace and air conditioner or heat pump come out, and the new equipment goes in, connected to the ductwork, the gas or electrical line, and the refrigerant lines. The contractor tests the system afterward to confirm it's heating and cooling properly and that every connection is sealed and safe. In most areas, including here, this work needs a permit from the local building office, and an inspector checks it once it's finished. That inspection confirms the work was done to code, so it's worth asking about if the contractor doesn't bring it up.
