A system that works almost the whole year
In Shawnee, a heating and cooling system has almost no season off. Homes here need heat from November through April, when winter nights average 30°F, then switch to cooling from May through September, with afternoons averaging 92°F. That is 11 months of the year one system or the other is running.
Storms are part of the picture too. The area has seen 6 winter storms and 57 damaging wind events over the past ten years, and a quarter of Oklahoma households lost power for at least 24 hours in 2024. A new system is worth planning around the chance the power goes out with it.

Oklahoma requires HVAC contractors to hold a state license.
The Construction Industries Board issues that license, and it belongs to the contractor, not to any single job. It is what the state has on file for the business doing the work, tested and registered with the board.
For an installation like this, the permit is what puts a second set of eyes on the job. In most cities and counties, putting in a new furnace, air conditioner or heat pump needs a permit from the local building office, and the work gets inspected once it's done. That inspection is separate from the license itself and happens at the local level, not through the state board.

- When should I replace my HVAC system?
- Once repairs start happening every year, or the system is old enough that a breakdown would leave you without heat or air conditioning for days, it is time to plan a replacement. Homes here need heat from November through April and cooling from May through September, so there are only a few weeks a year when a system going down would not leave you uncomfortable. Watch for rising repair costs, uneven temperatures room to room, and a unit that runs constantly without keeping up. A contractor can tell you whether the system in front of them is worth another repair or not.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, replacing them together often makes sense, but it depends on the condition of each one. A furnace and air conditioner installed years apart may not be matched well, and a mismatched system can run less efficiently than two units built to work together. If your furnace is failing and your air conditioner still has years left, replacing just the furnace is reasonable. A contractor can look at the age and condition of both and tell you what fits your situation.
- What happens during an HVAC installation?
- The contractor removes the old furnace and air conditioner or heat pump and installs the new equipment, usually in the same locations. This includes connecting the ductwork, running refrigerant lines, wiring the electrical connections, and setting up the thermostat. 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. Ask the contractor about the permit before the work starts and make sure it gets pulled for the job.
