Fairmont asks a lot of a heating and cooling system
Your furnace has to carry the house from October through May. That's eight months a year, with winter nights averaging 24°F from December through February. A system sized wrong for that stretch either runs constantly trying to keep up or cycles too often and wears down early.
Summer is shorter here, three months of afternoons averaging 82°F, but the system still has to keep up with it. Between the two seasons, something in the house is working most months of the year. Most homes here heat with gas, so the furnace and the air conditioner usually get sized and installed as a pair. Storms are part of the picture too. Marion County has seen 57 damaging wind events and 5 winter storms over the past ten years, and statewide, 35% of households went at least 24 hours without power in 2024. A new system installed correctly, with the electrical work done right, is what gets the house back to warm or cool once the power is back.

West Virginia requires HVAC contractors to hold a state license.
The license is issued to the contractor by the state, through the Commissioner of Labor, and it stays attached to that contractor rather than to any single job. That means the same license covers this installation and the next one, and the state has a record of who holds it.
For an install like this, the license tells you the contractor is the one the state has on file. Whether the job itself gets checked is a separate matter, and in most cities and counties that check comes from the local building office, which requires a permit for a new furnace, air conditioner or heat pump and inspects the work once it is done.

- When should I replace my HVAC system?
- Once repairs start happening every season, replacement usually makes more sense than another fix. A furnace or air conditioner that keeps breaking down is telling you the same thing each time it happens. Homes here need heat or cooling 11 months out of the year, so a failing system does not get much of a break to hide the problem. If your energy bills have crept up without another explanation, that is often the equipment losing efficiency as it ages.
- Should I replace my furnace and air conditioner at the same time?
- If both are original to the house and close in age, replacing them together is usually worth considering. A furnace and air conditioner installed at the same time tend to wear out around the same time too, so fixing one often means the other is not far behind. Matching the new furnace and coil also lets a contractor size the whole system properly for your house instead of working around older equipment. If one unit is much newer than the other, there is no reason to replace something that still has years left in it.
- What happens during an HVAC installation?
- A contractor removes the old furnace and air conditioner, then sets the new equipment in place and connects it to your ducts, gas line or electrical circuit, and refrigerant lines. They test the system afterward to check that it heats and cools correctly and that airflow and refrigerant charge are right. In most cities and counties this work needs a permit from the local building office, with an inspection once the job is done. The exact steps depend on the house and the equipment, so a contractor will walk you through what your installation involves.
