Your new system needs to handle both ends of the year
In Oklahoma County, a furnace and an AC both earn their keep. Heat runs October through April, seven months, with winter nights averaging 30°F. Cooling runs May through September, with summer afternoons averaging 92°F. That is 12 months where the system is working, one season or the other, with barely a break between them.
Most homes here heat with gas. Whatever you install has to hold up through wind storms and winter storms alike. Oklahoma has seen 253 damaging wind events and 15 winter storms over the past ten years, and a quarter of households in the state lost power for at least 24 hours in 2024. A new system should be sized and installed to start back up on its own once the power does.

Oklahoma requires HVAC contractors to hold a state license.
The state tested this contractor before handing out the license, and the Construction Industries Board keeps a record of who holds one. That license belongs to the contractor, not to this particular job, so it tells you the business met the state's standard, not that this installation was checked by anyone after the fact.
That second part comes from the local building office. A furnace and air conditioner installation in most cities and counties in Oklahoma County needs a permit before the work starts and an inspection once it's done, and that inspection is what confirms the gas connections, the wiring and the ductwork were put together right in your house.

- When should I replace my HVAC system?
- Replace it when repairs start coming often, or when the system can't keep up during the cold nights from December through February or the hot afternoons from May through September. An older furnace or air conditioner that breaks down every year is costing you in comfort even before it costs you in repair calls. A contractor can look at the age and condition of what you have and tell you whether another repair makes sense or whether you're better off starting over.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, yes, it's usually the better time to do it. Your furnace and air conditioner share a coil and often share a blower, so a mismatched pair, one new and one worn out, can run less efficiently than a matched system would. Homes here need heat from October through April and cooling from May through September, so there's no season where either one is idle for long. If only one has failed, a contractor can tell you whether the other has enough life left to wait.
- What happens during an HVAC installation?
- A contractor removes the old furnace, air conditioner or heat pump and sets the new equipment in place, then connects it to your ductwork, gas line or electrical circuit and the refrigerant lines. Oklahoma requires HVAC contractors to hold a state license through the Construction Industries Board, and in most cities and counties here, this job needs a permit from the local building office plus an inspection once the work is done. After everything is connected, the contractor tests the system to make sure it's heating and cooling correctly before calling the job finished.
