A system that works nearly all year here
Laurel County needs heat from October through April and cooling from June through September. That is 11 months where your system is doing one job or the other. Winter nights average 28°F, cold enough that a furnace or heat pump runs often across those months. Summer afternoons average 84°F, so the cooling side gets real work too.
Most homes here heat with electricity, so when the power goes out, the heat goes with it. Laurel County has seen 16 winter storms and 115 damaging wind events over the past ten years, and last year nearly a quarter of Kentucky households lost power for 24 hours or more. A new system installed here has to hold up to the cold it runs against and keep working through the storms that knock out power.

Kentucky requires HVAC contractors to hold a state license.
The state license is issued to the contractor, not to each job, so it covers this installation the same as any other work they do. Kentucky's Department of Housing, Buildings and Construction is the body that tested them and keeps that record.
For a system installation like this one, the license tells you the contractor was tested and is on record with the state. The permit is separate from that. In most cities and counties here, putting in a new heating and cooling system needs a permit from the local building office, and the work gets an inspection once it is done.

- When should I replace my HVAC system?
- Once a furnace or air conditioner is old enough that repairs keep coming back, replacing it makes more sense than fixing it again. Parts get harder to find as a system ages, and they start failing faster than they can be swapped in one at a time. Homes here run the heat from October through April and the air conditioner from June through September, so both sides of the system carry real hours every year. If your energy bills have crept up with no other explanation, or the system struggles to keep up on the coldest or hottest days, that is worth a look too.
- 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 were matched to work as a pair, and pairing an old unit with a new one can mean neither performs the way it should. It also means one visit and one inspection instead of two, since replacing either one needs a permit from the local building office. A contractor can look at both and tell you whether the one that still works has enough life left to wait.
- What happens during an HVAC installation?
- A contractor removes the old furnace, air conditioner, or both, and sets the new equipment in place, then connects it to the ductwork, gas line or electrical circuit, and the vent hood or condensate line it needs to run. The refrigerant lines get connected and sealed, the electrical and gas connections are checked, and the system gets tested through a full cycle before the job is called done. In most places here, this work needs a permit from the local building office, and an inspector checks it once it is finished. Kentucky requires the contractor doing this to hold a state license through the Department of Housing, Buildings and Construction.
