Seven months of heat, and storms that knock out power
Tahlequah needs a working furnace from October through April. That is seven months out of the year, with winter nights averaging 30°F. A new furnace has to be sized and installed to carry that whole stretch, not just the coldest week of it.
Nearly half of homes here heat with electricity. Oklahoma sees real power loss, with a quarter of households going at least 24 hours without it in 2024. Cherokee County has logged 9 winter storms and 58 damaging wind events over the past ten years. Any new gas furnace installed today has to meet the federal minimum of 80 percent AFUE, so a chunk of every dollar of fuel goes to heat rather than up the flue.

Oklahoma requires HVAC contractors to hold a state license.
The Construction Industries Board issues that license to the contractor, not to any single job. Passing the exam and getting on the board's record happens once, then the same license covers every furnace that contractor installs after that.
For this job, the license tells you the person doing the work was tested and is on file with the state. It does not stand in for a permit. In most cities and counties, installing a furnace still needs a permit from the local building office, and an inspection once the work is done, checking that the gas connection and venting were done right.

- What size furnace does my house need?
- It depends on your square footage, your ceiling height, how much insulation you have, and how many windows you have facing north. A contractor will run a load calculation on your house rather than go by rule of thumb. This matters more here than in a mild climate, since your furnace has to hold its own against winter nights averaging 30°F. A furnace that is too big will short cycle and wear out faster. One that is too small will run constantly and still leave you cold.
- How do I know it's time to replace my furnace?
- Age is one sign, along with repairs that keep coming back or cost more each time. Watch for uneven heat between rooms, a furnace that runs longer than it used to, or a rise in your gas or electric bill with no other explanation. If a technician tells you the heat exchanger is cracked, replace it. That part is not safe to patch. With homes here needing heat from October through April, seven months of the year, a furnace on its way out will make itself known fast.
- Is a high-efficiency furnace worth it?
- Every non-weatherized gas furnace made after November 19, 2015 has to hit at least 80 percent AFUE, so even the standard option now is decent. A high-efficiency furnace goes beyond that minimum and burns less gas to make the same heat, which matters over seven months of heating a year. The higher upfront cost pays back over time through lower gas bills, though how long that takes depends on your usage and your current furnace. A contractor can walk you through the numbers for your house.
