Seven months of heat, and nights that get down near freezing

Hickory homes run the furnace from October through April. That is most of the year, and winter nights here average 31°F, cold enough that the furnace is doing real work most of the times it kicks on.

Most homes in Catawba County heat with electricity, and storms here have knocked out power often enough to matter. Nine winter storms and 66 damaging wind events hit this area over the past ten years, and a quarter of North Carolina households lost power for at least a day in 2024. A new furnace installed here has to hold up to a full winter and start back up reliably after the power drops. Any new gas furnace also has to meet the federal minimum of 80 percent AFUE, so a good chunk of the heat it makes ends up in the house instead of out the flue.

North Carolina requires HVAC contractors to hold a state license.

The State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors licenses HVAC contractors in North Carolina, and that license belongs to the contractor, not to any single job.

For a furnace installation in Catawba County, that license is what stands behind the person doing the work. The installation itself also needs a permit from the local building office, as most cities and counties require for a furnace replacement, and an inspector checks the work once it's done.

What size furnace does my house need?
There's no single number that fits every house. Sizing comes from a load calculation that looks at your square footage, insulation, windows, and ceiling height, not just the size of the unit you're replacing. A furnace that's too big for the house will short cycle and wear out faster than one sized right. A contractor doing the installation should run this calculation rather than guess from the old equipment.
How do I know it's time to replace my furnace?
Watch how it's running, not just how old it is. Uneven heat between rooms, a furnace that takes longer to reach the same temperature, or a rising electric bill are all signs it's losing ground, especially if you're one of the 73.4% of households here heating with electricity. If a repair bill starts approaching what a new furnace would cost, replacement is usually the better move. A furnace installed after November 2015 has to meet an 80.0 percent AFUE minimum, so older equipment is likely running less efficiently than what's available now.
Is a high-efficiency furnace worth it?
It depends on how long you plan to stay in the house and what you're paying to heat it now. Winters here average 31°F and homes need heat from October through April, seven months a year, so a furnace runs a lot of hours over a season. A higher AFUE rating means less fuel burned for the same heat over that stretch, but the equipment costs more upfront. A contractor can compare your current furnace's efficiency against what a new one would offer before you decide.
