State College asks a furnace to work eight months a year
From October through May, your furnace is what keeps the house livable. Winter nights average 20°F, cold enough that the burner is cycling on and off most of the day and night for months at a stretch. A new furnace here needs to hold up to that kind of run time, not just handle the occasional cold snap.
Power can be part of the problem too. Over the last ten years, Centre County has seen 27 winter storms and 168 damaging wind events, and statewide, 15 percent of households went at least 24 hours without power in 2024. A furnace that runs on electricity to ignite and move air can go down when the power does. Any furnace installed today also has to meet the federal minimum of 80 percent AFUE, so at least that much of the fuel it burns turns into heat for the house.

Pennsylvania requires contractors to register with the state.
That registration puts the business on file with the state and nothing more. Nobody tests the contractor's gas work or checks their installs before they register. Pennsylvania also blocks cities and towns from layering their own HVAC license on top, so the registration is the only state-level record you get anywhere in the state.
For a furnace install, the protection that matters comes from the local building office instead. Most cities and counties require a permit for this job and an inspection once it's done, and that inspection is what actually checks the gas connection and the venting before anyone signs off on the work.

- What size furnace does my house need?
- There's no single number that works for every house. Sizing depends on your square footage, how much insulation you have, your window count and type, your ceiling height, and how the place is laid out. A contractor will run a load calculation on the actual house, not just measure the square footage. A furnace that's too big cycles on and off and never runs long enough to heat evenly. One that's too small runs constantly and still can't keep up when it's 20°F outside. Get the calculation done rather than going by what size the old unit was or what a neighbor's house has.
- How do I know it's time to replace my furnace?
- Age is the first thing to look at. Most furnaces last 15 to 20 years. Once you're past that, repairs start costing more and fixing less. Watch for signs beyond age too. Rooms that won't heat evenly, a furnace that cycles on and off more than it used to, a yellow flame instead of blue, or a repair bill that's a big fraction of what a new furnace would run. Homes here need heat from October through May, so a furnace that's struggling has eight months a year to prove it. If you're calling for repairs more than once a season, replacement is worth pricing out.
- Is a high-efficiency furnace worth it?
- It depends on how long you plan to stay in the house and how much you're paying to heat it now. Every new non-weatherized gas furnace sold has to hit at least 80 percent AFUE, so that's the floor, not the top. High-efficiency models are rated above that floor, meaning less of what you burn goes out the flue instead of into your rooms. With winter lows here averaging 20°F and heat needed eight months of the year, that difference gets used a lot. A contractor can look at your current furnace's AFUE and your usage to tell you what the upgrade would actually mean for this house.
