Eight months of heat, and nights that drop to 21°F
Phillipsburg homes need heat from October through May. That is eight months of the year the furnace has to work, not just the deep winter months. On the coldest nights it is holding a house warm against an average low of 21°F.
A furnace installed here now has to meet 80.0 percent AFUE, the federal minimum for non-weatherized gas furnaces built since November 2015. Half the homes in this area heat with gas, so that standard is the floor a new furnace has to clear before anything else about it matters. Warren County has also seen 20 winter storms and 167 damaging wind events over the past ten years, and statewide, 11 percent of households went at least a day without power in 2024. A furnace that starts reliably on its own once power comes back is worth having in a place where the power does not always stay on.

New Jersey requires HVAC contractors to hold a state license.
New Jersey licenses HVAC contractors through the State Board of Examiners of HVACR Contractors, and the board tests contractors before it licenses them. The license belongs to the contractor, not to any one job, so the same license that covered their last furnace install is what covers yours. Because the state holds this license, no town or city in Warren County can require its own license on top of it.
For a furnace installation, the license tells you the contractor was tested and is on record with the state. In most cities and counties, the job also needs a permit from the local building office, with an inspection once the furnace is in. That inspection is what catches a bad gas connection, which is the part of the job worth being careful about, and where it happens, that check comes from the local building office, not the state license.

- What size furnace does my house need?
- The right size depends on your home's square footage, insulation, windows, and layout, not on a rule of thumb. A contractor works this out with a load calculation that looks at your specific house room by room. A furnace that's too big cycles on and off too often and wears out faster. One that's too small runs constantly and still won't keep up on the coldest nights here, when winter lows average 21°F.
- How do I know it's time to replace my furnace?
- Watch for uneven heat between rooms, a furnace that runs longer than it used to, or repair calls that keep coming back. Age matters too. Homes here need heat from October through May, so a furnace that struggles in the shoulder months usually can't be trusted once the cold sets in. If a technician has told you the heat exchanger is cracked, that's not a repair, that's a replacement.
- Is a high-efficiency furnace worth it?
- It depends on how many months you run the furnace and what you're comparing it against. Homes here need heat eight months a year, October through May, so a furnace here works harder over its lifetime than one in a milder climate. Any furnace made after November 2015 already has to hit 80 percent AFUE at minimum, so the real question is whether a higher efficiency model pays for itself in your case. A contractor can walk you through the actual efficiency ratings and what they'd mean for your house.
