A system that runs almost all year in Tahlequah

Cherokee County only gets a break from heating or cooling for a few weeks a year. Furnaces here work October through April, seven months, and nights average 30°F through the coldest stretch of winter. Air conditioners take over May through September and run against afternoons that average 90°F. A new system needs to handle both ends of that range, not just one.

Oklahoma sees its share of ice and wind. Cherokee County has had 9 winter storms and 58 damaging wind events over the past ten years, and statewide a quarter of households lost power for at least 24 hours in 2024. Close to half the homes here heat with electricity, so when the power goes out, the furnace goes with it. Whatever gets installed should be sized and set up for a place that leans on it through a long winter and a hot summer, with storms in between.

Oklahoma requires HVAC contractors to hold a state license.

The Construction Industries Board tests and licenses HVAC contractors in Oklahoma, and it keeps a record of who holds that license. The license belongs to the contractor, not to any single job, so it does not expire when this installation is finished.

For an installation like this one, the license is what stands behind the person doing the work, but the city or county still has a say in Cherokee County. Putting in a new furnace, air conditioner or heat pump usually needs a permit from the local building office, and the finished job gets inspected before it is signed off. That inspection is separate from the state license and checks the work itself, not the contractor's paperwork.

When should I replace my HVAC system?
Once repairs start happening every year, or the system can no longer keep the house comfortable, replacement is usually the better move. An old furnace or air conditioner that breaks down mid season leaves you without heat or cooling right when you need it most, and here that season runs long, seven months of heat and five months of cooling with barely a break between them. If a contractor tells you the same part keeps failing, or your bills keep climbing while the house stays uneven, that system is telling you it is done.
Should I replace my furnace and air conditioner at the same time?
If both are old, yes, replacing them together usually makes sense. They run on the same ductwork and often share a blower, so pairing a new furnace with an aging air conditioner, or the reverse, can leave one part of the system working harder than it should. A contractor can look at the age and condition of each unit and tell you whether replacing one now and planning for the other later is the right call for your house.
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 your ductwork, gas or electric line, and condensate drain. After that comes the startup check. The contractor verifies refrigerant charge, checks airflow, and makes sure the thermostat is talking to the new system correctly. In most places, including here, this job needs a permit from the local building office and an inspection once the work is finished, so the contractor handling your installation should be pulling that permit as part of the job.
