Eleven months of work for one system in Norman
Norman only gets a real break from heating or cooling one month a year. Winter nights average 30°F from December through February, and summer afternoons average 92°F, so whatever you install has to handle both ends without much rest between them.
The furnace holds up through six months of winter, November through April. The air conditioner takes over for the other five, May through September. 55.6% of homes here heat with gas. New equipment sold today has to meet the federal minimum efficiency rating, so the bigger question is sizing it right for a Norman house and getting it installed well. A quarter of Oklahoma households lost power for at least 24 hours in 2024, and the last ten years here brought 10 winter storms and 163 damaging wind events, so what's installed and how it's protected matters as much as the equipment itself.

Oklahoma requires HVAC contractors to hold a state license.
The Construction Industries Board issues that license after testing the contractor, and it keeps a record of who holds one. The license belongs to the contractor, not to any one job, so it stands behind every installation they do, not just this one.
For a job like this, that license is the thing accountable for the work. In most cities and counties, installing a new heating and cooling system also needs a permit from the local building office, with an inspection once the work is finished.

- When should I replace my HVAC system?
- Replace it when it can no longer heat or cool the house reliably, or when repairs keep coming back. An aging system works harder and loses efficiency even when it still runs, and that shows up in the utility bill before it fails outright. Homes here need heat or cooling 11 months out of the year, so a system on its way out does not get much of a break to fail quietly. If a contractor is out at your house more than once for the same problem, that is usually the sign to stop repairing and start planning the replacement.
- Should I replace my furnace and air conditioner at the same time?
- If they are close in age, yes, it usually makes sense to replace them together. A furnace and air conditioner installed at the same time wear at the same rate, so replacing one while the other is near the end of its life often means paying for a second installation not long after the first. They also share parts of the system, like the blower and the coil, so a matched furnace and air conditioner are sized to work together correctly. If one is much newer than the other, a contractor can look at both and tell you whether the newer one is worth keeping for now.
- What happens during an HVAC installation?
- A contractor removes the old furnace and air conditioner or heat pump, then sets the new equipment in place and connects it to the ductwork, refrigerant lines, gas or electric supply, and condensate drain. The furnace and coil usually go in first, then the outdoor unit. Once everything is connected, the contractor tests the system, checks refrigerant charge and airflow, and confirms it heats and cools correctly before leaving. In most cities and counties, this job needs a permit from the local building office, and an inspector checks the work once it is done.
