Ten months of heating in Klamath Falls
Furnaces here run from September through June. That is ten months of the year. Winter nights average 22°F, so the burner is working hard for most of the calendar, not just a few cold snaps.
Klamath County has seen 72 winter storms and 86 damaging wind events over the past ten years, and in 2024, 20 percent of Oregon households lost power for at least 24 hours. A new furnace here needs to be sized right and installed to hold up through that kind of winter. If it is a standard gas furnace built new, federal rules already set the floor. It has to reach at least 80 percent AFUE.

Oregon requires HVAC contractors to hold a state license.
The license comes from Oregon's Construction Contractors Board and it belongs to the contractor, not to any single job. That means the state has tested and keeps a record of the business you hire, not just the crew that shows up. Work under $1,000 falls outside this requirement, but a furnace installation runs well past that, so the contractor doing this job needs to hold that license.
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. The license tells you the state has vetted who you hired. The permit and inspection tell you someone independent looked at what they did. In Klamath County, 42.8% of homes heat with gas, so a furnace that is not installed right is a problem for a lot of households here, not a rare one.

- What size furnace does my house need?
- It depends on your square footage, your insulation, your windows, and how your ductwork is laid out, so there is no single number that fits every house. A contractor sizes it with a load calculation, not a chart based on square feet alone. This matters here because winter nights average 22°F, and a furnace that's too small will run constantly without ever catching up to that cold. Get a load calculation done rather than matching whatever size is already in there, since the old one may have been wrong too.
- How do I know it's time to replace my furnace?
- Watch for uneven heat between rooms, a furnace that cycles on and off more than it used to, or a gas bill climbing while comfort drops. Age matters too. Furnaces here run from September through June, ten months a year, so they get more hours of work than a furnace in a milder place ever sees. If a contractor is out repairing it more than once a season, or the repair costs start creeping toward what a new unit would run, that is usually the sign to stop patching it.
- Is a high-efficiency furnace worth it?
- Any gas furnace sold new today has to reach at least 80 percent AFUE by federal rule, so the real question is whether it makes sense to go higher than that. Heat is needed here from September through June, ten months a year, so a more efficient furnace has a lot of runtime to earn back its cost in lower gas bills. A contractor can walk through the numbers for your specific house and duct setup.
