Craig asks for heat every month of the year
Winter nights here average 32°F from December through February, and summer afternoons only reach 62°F. There is no real cooling season to plan around. What you are sizing a system for is heat, all year, in every month on the calendar.
A system that runs this much needs to hold up through more than cold. Over the past ten years this area has seen 20 winter storms and 20 damaging wind events, and across Alaska, 21% of households lost power for 24 hours or more in 2024. A new furnace or heat pump has to keep working through that, and so does whatever backup you have for when the power goes out.

Alaska requires contractors to register with the state.
That registration puts the business on file with the state. Nobody tests the contractor's trade knowledge to grant it, and nothing about it says whether their installs hold up. It tells you the business exists on paper, not that the work will be done right.
For a heating and cooling install, the protection in Prince of Wales-Hyder comes from the local building office instead. Replacing a furnace, air conditioner or heat pump needs a permit in most places, and an inspector checks the finished work before it's signed off. That inspection is what catches a bad gas connection or a system put in wrong, not the state registration.

- When should I replace my HVAC system?
- Replace it when repairs start costing more than they're worth or when the system can't keep the house warm anymore. In Craig, the furnace runs all year, so a failing one isn't a minor inconvenience you can put off until spring. Watch for a furnace that cycles constantly, one that can't hold a set temperature, or one that's needed repair more than once in the past year. A contractor can look at its age and condition and tell you whether another repair makes sense or whether it's time for a new unit.
- Should I replace my furnace and air conditioner at the same time?
- In Craig, this mostly comes down to the furnace alone. Homes here don't need cooling, with summer afternoons averaging 62°F, so there's usually no air conditioner in the mix to begin with. If your home does have one, replacing both at once can make sense if they're the same age and share a blower, but a contractor can tell you whether that applies to your setup.
- What happens during an HVAC installation?
- A contractor removes the old furnace, sets the new one in place, and connects it to the existing ductwork, gas line or electrical supply, and venting. After that, they test the ignition, check the airflow, and confirm the thermostat is talking to the new unit correctly. Since heat runs year round here, the contractor will also make sure everything is sealed and venting properly before they consider the job done, since there's no mild season to catch a problem later.
