What Salem County winters ask of a new furnace
Your furnace has to carry the house from October through April. That's 7 months a year it needs to work, on nights that average 28°F. A furnace here isn't sized for a mild stretch with a few cold snaps. It's sized to run most of the fall, all winter, and into spring.
Any new gas furnace installed today has to reach at least 80.0 percent AFUE, the federal minimum for a non-weatherized unit. Almost half the homes in the area heat with gas, so this is the standard most new installs are held to here. Salem County has also seen its share of winter storms and damaging wind over the past decade, and outages happen. Worth asking a contractor how the furnace you choose holds up when the power blinks or a storm rolls through.

New Jersey requires HVAC contractors to hold a state license.
New Jersey licenses HVAC contractors through the State Board of Examiners of Heating, Ventilating, Air Conditioning and Refrigeration Contractors. The board tests the contractor and keeps a record of the license, and that license covers the business, not each individual job. Salem County and the towns in it cannot add their own license on top of the state's. Whatever the state licensed is what you get here.
A furnace installation still needs a permit from the local building office in most cities and counties, along with an inspection once the work is done. That inspection is what catches a bad gas connection, which is the dangerous part of this job. Close to half of Salem County's homes heat with gas, so a properly checked connection matters here as much as the license itself.

- What size furnace does my house need?
- The right size depends on your home's square footage, insulation, window count, and layout, so there's no number that fits every house. A furnace that's too big cycles on and off too fast and never heats evenly. One that's too small runs constantly and still can't keep up on the coldest nights, which here means down around 28°F. A contractor sizes it with a load calculation on your actual house, not a guess based on square footage alone.
- How do I know it's time to replace my furnace?
- Rising repair bills, uneven heat between rooms, and a furnace that runs longer to hit the same temperature are the main signs. Age matters too. Furnaces built after November 2015 have to hit at least 80 percent AFUE, so if yours is older than that, it may be well below that mark now. With heat needed here from October through April, a furnace that struggles in early fall or late spring will likely fail you in the middle of winter. If a repair is starting to cost close to what a new unit would, replacement usually makes more sense.
- Is a high-efficiency furnace worth it?
- It depends on how long you plan to stay in the house and how much you run the furnace. Homes here need heat seven months a year, so a furnace gets heavy use, more than in milder climates. A high-efficiency model burns less gas to produce the same heat, which matters most where gas is the primary fuel. Salem County has close to half its homes heating with gas, so for a lot of houses here the fuel savings add up over a full season. A contractor can walk through the actual models and price against your current setup.
