Twelve months of work, in Tulsa County heat and cold

There's no real off season here. Furnaces run October through April, seven months, on nights that average 29°F. Air conditioners take over May through September, five months, on afternoons that average 91°F. Whatever system you install has to handle both ends of that, not just one.

Most homes in Tulsa County heat with gas. A new furnace paired with a new AC has to meet the federal efficiency minimum, and both sides need to be sized for what this place actually does, not a mild version of it. Storms are part of the picture too. The area has logged 276 damaging wind events and 10 winter storms over the past ten years, and a quarter of Oklahoma households lost power for at least 24 hours in 2024. A new system won't run without power, but how it comes back on when the power returns is worth asking about before it's installed.

Oklahoma requires HVAC contractors to hold a state license.

The Construction Industries Board tests contractors before it licenses them, and it keeps a record of who holds that license. That license belongs to the contractor, not to any single job, so the same license covers this installation and whatever work that contractor takes on next.

For a system swap like this, the license is what stands behind the person doing the work. The job itself still needs a permit from the local building office in most cities and counties, and an inspection once the installation is done.

When should I replace my HVAC system?
Replace it when repairs stop making sense or the system can't get through the year here without breaking down. Homes in Tulsa need heat or cooling every month of the year, so there's no season where a failing system can just wait. If your furnace or air conditioner is old enough that parts are getting hard to find, or you're calling for repairs more winters and summers than not, that's usually the point to stop patching it. A contractor can look at the specific unit and tell you whether another repair is worth it.
Should I replace my furnace and air conditioner at the same time?
If they're close in age, replacing them together often makes sense, but it depends on the condition of each one. A furnace and air conditioner installed at the same time tend to wear out around the same time too, so if one is failing the other may not be far behind. Tulsa homes run the furnace seven months a year and the air conditioner five, so both units get real use and neither one is idle long enough to hide a problem. A contractor can check the age and condition of both and tell you whether it's worth doing now or waiting on the second one.
What happens during an HVAC installation?
A contractor removes the old furnace and air conditioner and sets the new ones in place, then connects them to the ductwork, gas line or electrical circuit, and the refrigerant lines. Once everything is connected, the system gets tested to make sure the heat exchanger, the coil and the thermostat are all working together correctly. In most Oklahoma cities and counties this job needs a permit from the local building office, and an inspector checks the work when it's done. Oklahoma also requires the contractor doing the work to hold a state license through the Construction Industries Board.
