In Valdez, your furnace never really gets a break
Winter nights here average 23°F from December through February, and homes in this part of Alaska need heat all 12 months of the year. There is no real off season for the furnace, no stretch of months where it sits idle. It runs, and it needs to keep running.
Most homes here heat with fuel oil rather than gas. If a gas furnace is part of the plan, any new non-weatherized unit built since November 2015 has to meet 80.0 percent AFUE by federal rule, so that baseline is already covered no matter which model goes in. Power outages happen in this state too. In 2024, 21 percent of Alaska households went at least a full day without power at some point, worth keeping in mind for whatever furnace and backup setup ends up in your home.

Alaska requires contractors to register with the state.
Registration puts the business on file with the state. Nobody tests the contractor's work to get on that list, and nothing about it says whether they install a furnace correctly. It is a record, not a credential.
With no state license behind this job, the permit is what stands in its place. In most cities and counties, replacing a furnace needs a permit from the local building office, and an inspector checks the completed work before it's signed off. That inspection is what confirms the venting and gas connection were done right, not the registration.

- What size furnace does my house need?
- The right size depends on your home's square footage, how well it's insulated, its window count, and its layout, not just a rule of thumb. A contractor will run a load calculation on your actual house to get this number. That matters more here than in most places, since your furnace needs to hold its own against 23°F nights, and one sized wrong will either run constantly or short cycle and wear out early.
- How do I know it's time to replace my furnace?
- If it's struggling to keep up, cycling on and off more than it used to, or needing repairs every season, it's time to start planning a replacement. With heat needed here 12 months a year, an aging furnace working harder than it should adds up fast in wear. If yours is a non-weatherized gas furnace installed since November 2015, it's required to run at 80 percent AFUE or better. An older, less efficient furnace is worth comparing against a new install, and a contractor can tell you what condition yours is really in.
- Is a high-efficiency furnace worth it?
- For a home that needs heat all 12 months of the year, a high-efficiency furnace has more chances to pay off than it would somewhere with a short heating season. Most homes here heat with fuel oil, and a furnace that pulls more heat from every unit of fuel burned means less fuel used over that much run time. A contractor can walk through the actual models and their AFUE ratings for your house, since cost isn't something to guess at here.
