A system that works nearly the whole year here
La Grange asks a lot of a heating and cooling system. Winter nights average 26°F from December through February, and a new furnace or heat pump needs to hold up against that kind of cold for the full stretch from October through April. Come summer, afternoons average 86°F, and the same system has to switch over and keep the house cool from May through September. Add it up and there are only a few weeks a year when a system here gets a real break.
Oldham County has also seen its share of rough weather, with 60 damaging wind events and 10 winter storms recorded over the past ten years, and close to a quarter of Kentucky households lost power for at least a day in 2024. A new installation should be matched to what the winters and summers here actually demand, not just sized to replace what was there before.

Kentucky requires HVAC contractors to hold a state license.
Kentucky licenses HVAC contractors through the Department of Housing, Buildings and Construction. The license belongs to the contractor, not to this one job. That means the state tested this contractor and keeps a record of them, apart from whatever gets installed at your house this week.
For an installation like this one, that license is what stands behind the contractor's work. In most cities and counties, putting in a new furnace or air conditioner also needs a permit from the local building office, with an inspection once the work is done. That inspection is what catches a bad connection or a system put in wrong, on top of whatever the license already vouches for.

- When should I replace my HVAC system?
- Once your system is breaking down more than once a season, or the repairs keep adding up, it is time to start pricing a replacement instead of fixing it again. Age matters too. A furnace or air conditioner working hard for years loses efficiency even when it still runs. Homes here need heat from October through April and cooling from May through September, so the equipment runs nearly year round with little rest. If your system is struggling to keep up on the coldest nights or the hottest afternoons, that is a sign it is falling behind, not just aging.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, replacing them together often makes more sense than doing one now and the other later. A furnace and air conditioner installed years apart may not be matched to work well together, and the newer unit ends up compensating for the older one. If only one has actually failed, a contractor can tell you whether the other is worth pairing with new equipment or still has good years left. A contractor will price the job for the specific house.
- What happens during an HVAC installation?
- A contractor removes the old furnace and air conditioner or heat pump, then sets the new equipment, connects it to the ductwork, wiring, and refrigerant lines, and tests it before finishing the job. In most cities and counties this work needs a permit from the local building office, and an inspector checks the completed installation. Kentucky requires HVAC contractors to hold a state license, and that license covers the contractor doing the work, not the specific job. Ask to see it before work starts.
