A system that has to work most of the year in Keyser
Your furnace needs to run from October through May here, 8 months a year. Winter nights average 24°F from December through February, and a new furnace has to hold the house steady through nights that cold, again and again.
Summer is shorter but it still counts. Afternoons average 85°F from June through August, so the system you install has to handle both jobs, heat for eight months and cooling for three, with only a few weeks between one and the next. Over half the homes here heat with electricity, and storms are common enough in West Virginia that many households lose power for a day or more. Ask any contractor how the system you're considering comes back on once power returns.

West Virginia requires HVAC contractors to hold a state license.
The license is issued to the contractor by the state's Commissioner of Labor, not to any single job. That means the same license has to be on file whether the work is a furnace swap in Keyser or a heat pump install anywhere else in the county. It tells you the state has tested and recorded that contractor, not that this particular installation has been checked.
That check comes after the fact, through the local building office. Installing a new heating and cooling system in most cities and counties means pulling a permit and having the finished work inspected before it's signed off. That inspection is what confirms the gas connections, the wiring and the refrigerant lines were done right on this job, separate from whatever the contractor's license already says about them.

- When should I replace my HVAC system?
- Once repairs start coming often, or the system is old enough that another breakdown feels like a matter of when, not if. A furnace or air conditioner nearing the end of its life tends to run longer to hit the same temperature, and the energy bills usually show it. Homes here need heat from October through May and cooling in June through August, so the system is working most of the year and a failing one gets noticed fast. If a contractor has already been out more than once this year for the same unit, replacement is worth pricing against another repair.
- Should I replace my furnace and air conditioner at the same time?
- If both are old, yes, it usually makes sense to do them together. A furnace and air conditioner installed at the same time are matched to work as one system, and pairing an old unit with a new one can leave the new one working around the old one's limits. It is not required though. If one unit still has years left in it, a contractor can replace just the one that needs it and size the new equipment to match what is staying.
- What happens during an HVAC installation?
- The contractor removes the old equipment, sets the new furnace, air conditioner, or heat pump in place, and connects it to the ductwork, gas or electric line, and condensate drain. Refrigerant lines get connected and tested for leaks, and the system is run through a full cycle to check airflow, temperature, and that everything is working the way it should. Most cities and counties require a permit for this work and an inspection once it is done, so the contractor should be handling that as part of the job.
