Six months of heat, and winters that knock the power out
Chickasha needs a working furnace from November through April. That is half the year, with winter nights averaging 30°F. A new furnace has to start reliably on cold mornings and keep running through a long stretch of cold, not just handle a few hard freezes.
Grady County has seen 7 winter storms and 145 damaging wind events over the past ten years, and a quarter of Oklahoma households lost power for at least 24 hours in 2024. Almost half the homes here heat with electricity, so an outage during a cold snap is not a small thing. Any new furnace installed today, gas or electric, has to meet the federal minimum of 80 percent AFUE if it runs on gas.

Oklahoma requires HVAC contractors to hold a state license.
Oklahoma licenses HVAC contractors through the Construction Industries Board. That license belongs to the contractor, not to any one job, so the same license covers this furnace installation as any other work that contractor takes on.
For a furnace installation in Grady County, that license is what stands behind the work. It is not the only check. Most cities and counties require a permit for a furnace replacement, and an inspection once the job is done, so someone from the local building office looks at the work separately from whatever the contractor tells you about it.

- What size furnace does my house need?
- The right size depends on your home's square footage, insulation, window count, and layout, so there is no single number that fits every house. A furnace that is too big will short cycle and wear out faster. One that is too small will run constantly and still leave rooms cold on a 30°F night. A contractor works this out with a load calculation, not a guess based on the old furnace's size.
- How do I know it's time to replace my furnace?
- If your furnace is struggling to keep up on cold nights, cycling on and off more than it used to, or needing repairs every winter, it is time to start looking at replacement. Age matters too. Furnaces installed new after November 2015 have to meet 80 percent AFUE, so if yours predates that, it is likely running less efficiently than what you'd get today. Homes here need heat from November through April, six months of the year, so a furnace that is already struggling now will only get worse as winter sets in.
- Is a high-efficiency furnace worth it?
- A high-efficiency furnace burns less gas to make the same heat, which matters most in a place that runs the furnace for six months a year with winter nights averaging 30°F. The higher the AFUE rating, the less fuel is wasted out the vent. Whether the higher upfront cost makes sense for your house depends on your current furnace's efficiency and your gas usage, and a contractor can walk through those numbers for your specific home.
