Seven months of heat, and nights that drop into the 30s
Winston-Salem homes need the furnace running from October through April. That is seven months out of twelve, with winter nights averaging 30°F. A new furnace has to hold up to that stretch every year, not just get through the coldest week.
Most furnaces installed now have to meet a federal minimum of 80 percent AFUE, so a share of every dollar of fuel goes out the flue no matter what you buy. Most homes in Forsyth County heat with electricity, and the power here does go out. The county has seen 12 winter storms and 174 damaging wind events over the past ten years, and a quarter of North Carolina households lost power for at least 24 hours in 2024. Worth asking how a new furnace handles a cold house and a dead grid at the same time.

North Carolina requires HVAC contractors to hold a state license.
The State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors licenses HVAC contractors in North Carolina. That license belongs to the contractor, not to any single job. It means the state tested this contractor and keeps a record of them. It does not mean this particular furnace installation gets reviewed by the state.
That review comes from the local building office instead. In most cities and counties, replacing a furnace needs a permit, and the finished work gets an inspection before it is signed off. That inspection is what catches a bad gas connection, which is the part of this job that can actually hurt someone.

- What size furnace does my house need?
- The right size comes from a load calculation, not the square footage of your house alone. A contractor works through your insulation, your windows, your ceiling height, and how the house holds heat through the winter months here. A furnace that's too big will short cycle and wear out early, and one that's too small will run constantly and still leave you cold on the 30°F nights. There isn't a shortcut number that works for every home, so this is worth having done properly before you install.
- How do I know it's time to replace my furnace?
- Age is the first thing to look at, along with how often you're calling for repairs. Watch for uneven heat between rooms, a furnace that runs longer than it used to, or a rise in your heating bills without a reason. If a technician has been out more than once this winter for the same problem, that's usually the point to stop repairing and start pricing a replacement, especially with 7 months of heating season ahead of you here. A contractor who looks at the unit can tell you whether it's worth fixing again or worth replacing.
- Is a high-efficiency furnace worth it?
- It depends on how long you plan to stay in the house and what furnace you have now. Any furnace built after November 2015 has to reach at least 80 percent AFUE, so even a standard unit today is not a poor performer. A high-efficiency model burns less gas to make the same heat, which matters more here given the 7 months a year this area needs heat running. A contractor can walk through the difference in equipment cost against what you'd save over the years you plan to stay, since that's the real comparison.
