Gastonia asks a system to run almost all year

Heat runs October through April here, seven months of the year. Cooling picks up in May and holds through September. That leaves only a few weeks a year when the system is not carrying one load or the other, so a new furnace or heat pump has to hold up under near constant use.

Winter nights average 32°F, mild enough that a heat pump can carry most of the heating load on its own. Summer afternoons average 88°F, and the same system has to bring that down every day for five months straight. 57.3% of homes here heat with electricity, which makes a heat pump's efficiency in both directions worth checking closely when you compare systems.

Storms are part of the picture too. Gaston County has logged 67 damaging wind events and 6 winter storms over the past ten years, and 25% of North Carolina households went at least 24 hours without power in 2024. A furnace with a standing pilot keeps working without power. Most systems, gas or electric, come back on by themselves once power returns.

North Carolina requires HVAC contractors to hold a state license.

The State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors tests contractors before they can hold this license, and the license belongs to the contractor, not to any single job. That means the person or company doing your installation carries that license into every home they work in, not just this one.

For a heating and cooling installation, that license is what stands behind the work itself. In most cities and counties, replacing a furnace, air conditioner, heat pump or water heater also needs a permit from the local building office, with an inspection once the work is done.

When should I replace my HVAC system?
Once a furnace or air conditioner is well into its second decade and starts needing repairs more than once a season, replacing it usually makes more sense than fixing it again. Watch for signs like uneven heating or cooling between rooms, a jump in your energy bills, or a system that runs constantly without keeping up. Homes here run the heat or the air for all 12 months of the year, so a system on its last legs does not get much rest to reveal the strain. If you are patching the same unit every winter or summer, have a contractor look at whether the repair cost makes sense against a new system.
Should I replace my furnace and air conditioner at the same time?
If both are close in age, replacing them together is often the better choice, since a furnace and air conditioner installed years apart can end up mismatched in capacity or efficiency. A furnace and AC that were sized as a pair tend to run more smoothly than one new unit paired with one old one. That said, if one system still has years of reliable life left, there is no rule that says you have to replace both at once. A contractor can look at the age and condition of each unit and tell you honestly whether pairing the work makes sense for your house.
What happens during an HVAC installation?
A contractor removes the old furnace, air conditioner or heat pump and sets the new equipment in place, then connects it to your ductwork, electrical, and for gas furnaces, the gas line. They check the refrigerant lines on an air conditioner or heat pump, test the thermostat wiring, and run the system through a cycle to confirm it heats and cools correctly. In most cities and counties around Gastonia, this work needs a permit from the local building office, and the job gets inspected once it is done. That inspection is there to confirm the installation was done to code, so it is worth asking your contractor whether they are pulling the permit before work starts.
