In Delta Junction, the furnace never really stops
Winter nights here average -10°F from December through February, and heat is needed all twelve months of the year. There is no season off. A furnace or boiler sized for this place runs almost constantly through the cold months, and it has to hold up doing it. Summer afternoons average 69°F, so cooling is not what this system is built around. Fuel oil heats 56.3% of homes here, and a new system has to be matched to that fuel, not just to the building.
Power is the other piece. In Alaska, 21% of households went at least 24 hours without power in 2024, and this area has logged 12 damaging wind events over the past ten years. A new system installed here should come back on by itself once power returns, without someone having to relight or reset it by hand.

Alaska requires contractors to register with the state.
That registration puts the business on file with the state. Nobody tests the contractor's work to get on that list, so it is not a stand-in for a license and it does not tell you whether the crew knows how to size a heat pump or set up a furnace correctly.
For this job, the real check is local. In most cities and counties here, putting in a new furnace, air conditioner or heat pump needs a permit from the local building office, and an inspector looks at the work once it's done. That inspection is what catches a bad gas connection or a system that was not installed to code.

- When should I replace my HVAC system?
- Replace it when repairs get frequent, when the unit is old enough that parts are wearing out together, or when it can no longer keep the house warm on the coldest nights. Up here your furnace runs all year, so it puts on far more hours than a furnace in a milder place. A breakdown at -10°F is not something you can wait out, so a furnace nearing the end of its life is a bigger risk here than in most places. If yours is struggling to keep up or needing repairs more than once a season, it is worth having a contractor look at whether replacement makes more sense than another fix.
- Should I replace my furnace and air conditioner at the same time?
- Homes here do not need cooling, so this usually is not a choice you have to make. Most houses in Delta Junction run on heat alone, without central air conditioning. If your setup is different and does include an AC unit, a contractor can tell you whether replacing both together makes sense for your equipment, but for most homes here the real question is just about the furnace.
- What happens during an HVAC installation?
- A contractor removes the old furnace, sets the new one in place, and connects it to the ductwork, fuel line, venting, and electrical. Fuel oil heats a large share of homes in this area, so that hookup and the venting that goes with it are part of many installs here. Once it is connected, the contractor tests it, checks that it is drawing and venting correctly, and confirms it is heating the way it should before calling the job done. Alaska requires contractors to be registered with the state, so it is worth checking that before hiring one.
