Your new system runs nearly all year here
Hendersonville needs heat or cooling every month of the year. Winter nights average 30°F from December through February, and a new furnace or heat pump has to hold up through seven months of that, October through April. Then summer afternoons average 87°F, and the same system switches over and carries five more months of cooling.
57% of homes here heat with electricity, so a heat pump or electric furnace is doing real work on those cold nights, not just backing up a gas line. Storms are part of the picture too. In 2024, 20% of Tennessee households went at least 24 hours without power, and whatever gets installed needs to come back on correctly once the power does.

- When should I replace my HVAC system?
- Replace it when repairs start costing more than they used to, or when your equipment is old and struggling to keep up. Watch for signs like short cycling, rooms that never quite reach the temperature you set, or a system running nearly nonstop through the winter or summer months. Homes here need heat or cooling every month of the year, so a system on its last legs does not get much of a break. If a technician has already been out more than once this year for the same problem, that is usually your answer.
- Should I replace my furnace and air conditioner at the same time?
- If they are close in age, replacing both together usually makes sense. A furnace and air conditioner installed years apart often were not matched to work together well, and pairing an old unit with a new one can mean the new one never runs at its best. It also means one visit and one round of work instead of two, spaced a few years apart. A contractor can look at the age and condition of each and tell you whether one is close enough behind the other to make replacing both worth it now.
- 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 the condensate drain. They check the refrigerant charge, test the airflow, and confirm the thermostat is talking to the new system correctly. Before they leave, they should walk you through what the system does and answer questions about the new setup. The exact steps depend on whether you are keeping the same kind of system or switching to something different, like moving from a furnace to a heat pump.
