Seven months of heat, on nights near freezing

Broken Arrow homes need a working furnace from October through April. That's seven months of the year, with winter nights averaging 30°F. A new furnace here has to start easily and hold up to months of steady use, not just a few cold snaps.

Most homes in this area heat with gas, and any non-weatherized gas furnace built since November 2015 has to reach at least 80 percent AFUE. That's the federal floor, not a target, so it's worth knowing where the unit going into your home stands above it.

Oklahoma requires HVAC contractors to hold a state license.

The Construction Industries Board tests contractors before it issues this license, and the license belongs to the contractor rather than to any single job. That is the state's check on who is allowed to install a furnace in Oklahoma.

This license covers the contractor, not the installation itself. 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, and that permit is what puts a check on this specific job. In Wagoner County, 59.9% of homes heat with gas.

What size furnace does my house need?
The right size depends on your square footage, your insulation, your ceiling height, and how many windows you have facing north. A furnace that's too big will short cycle, turning on and off before it heats evenly. One that's too small will run constantly and still leave rooms cold during the winter. A contractor works this out with a load calculation, not a chart based on square footage alone, since two homes the same size can need different furnaces.
How do I know it's time to replace my furnace?
Watch for rising repair bills, uneven heat between rooms, and a furnace that runs longer than it used to just to hold the same temperature. Furnaces wear out over time, and older units get harder to find parts for, so failures start coming more often. If yours needs heat every month from October through April here and a repair keeps failing, that is a sign to stop patching it. A contractor can tell you whether what you're seeing points to a fix or a replacement.
Is a high-efficiency furnace worth it?
It depends on how long you plan to stay in the house and what your current furnace costs to run. Every new non-weatherized gas furnace sold since November 2015 has to hit at least 80 percent AFUE, so even a standard replacement today is more efficient than an older unit. High-efficiency models push that number higher, which matters more here since homes need heat seven months of the year. Whether the higher price pays off for your situation is something a contractor can walk through with you using your actual furnace and your actual gas bills.
