Seven months of heating in Alamogordo
Your furnace runs from October through April here, seven months of the year. Winter nights average 28°F, so it is working through most nights in a New Mexico winter, not just the coldest stretch.
A new furnace installed here has to be a non-weatherized gas model built to reach at least 80.0 percent AFUE, the federal minimum. Just over half of homes in the area heat with gas, so most furnaces going in are built to that standard.

New Mexico requires HVAC contractors to hold a state license.
New Mexico licenses HVAC contractors through the Construction Industries Division. That license belongs to the contractor, not to any one job, so it tells you the person or company doing the work passed the state's exam and is on record with New Mexico. It does not mean this particular furnace install gets checked by the state before or after it happens.
That check, where it exists, comes from the local building office. In most cities and counties, a furnace installation needs a permit and an inspection once the work is done, and that inspection is what catches a bad gas connection or a venting mistake. Gas heat runs more than half the homes in Otero County, which is the kind of job where that inspection step matters most.

- What size furnace does my house need?
- It depends on your home's square footage, ceiling height, insulation, and window count, so there's no single number that works for every house. A contractor works this out with a load calculation, not a rule of thumb based on your old furnace's size. Going bigger than you need isn't a safety margin, it causes the furnace to short cycle and wear out faster. Winter lows here average 28°F and homes need heat for 7 months of the year, so a furnace sized wrong will show it.
- How do I know it's time to replace my furnace?
- Watch for repairs that keep coming back, or rooms that stay cold no matter what the thermostat says. If a technician tells you the heat exchanger is cracked, that's a replace, not a repair. Rising gas bills with no change in how you use the thermostat point to a furnace losing efficiency. With heat needed here from October through April, a furnace on its way out shows itself fast once the cold nights start.
- Is a high-efficiency furnace worth it?
- Any furnace installed new today has to reach at least 80 percent AFUE, so the real question is whether to go higher than that minimum. A furnace with a higher AFUE rating burns less gas to produce the same heat, and that adds up over 7 months of heating season here. It also needs a different vent setup than a standard furnace. A contractor can price both options for your house and tell you what your home's venting allows.
