Juneau asks a furnace to run all year
There is no season off here. Winter nights average 26°F from December through February, and summer afternoons only reach 63°F, so cooling never really enters into it. A system here is chosen and sized for heat, all year, not for switching between heat and cool. Close to half of homes in the borough heat with fuel oil, so whatever gets installed has to work with that setup or replace it.
Juneau has logged 18 winter storms and 13 damaging wind events over the past ten years. Across Alaska, a fifth of households went at least 24 hours without power in 2024. A furnace that comes back on by itself once power returns matters here.

Alaska requires contractors to register with the state.
Registration puts the business on file with the state. It does not mean anyone tested the contractor's work or checked their training. There is no trade exam behind it, so the number a contractor gives you confirms they are on record, nothing more.
For an installation like this, the protection comes from the local building office, not from the state. Replacing a heating and cooling system needs a permit in most cities and counties, and an inspector checks the finished work when the job is done, including the connections that matter most if they are done wrong. That inspection is what stands behind the installation here.

- When should I replace my HVAC system?
- Once your furnace needs frequent repairs, or the repairs start costing more than they're worth, replacement usually makes more sense than fixing it again. In Juneau your furnace runs all year, not just a few months, so it puts in more hours than one in most other places. Watch for uneven heat, rising fuel bills, or a system that short cycles. A contractor can look at the furnace itself and tell you whether it's worth repairing again.
- Should I replace my furnace and air conditioner at the same time?
- Homes here don't need cooling, so this isn't really a decision most Juneau homeowners face. If your home does have central air installed for some other reason, the answer still comes down to the age and condition of each system rather than replacing both out of habit. A contractor can check both and tell you if one needs attention now and the other doesn't.
- What happens during an HVAC installation?
- A contractor removes the old furnace, sets the new one in place, and connects it to your ductwork, venting and fuel or power supply. Close to half of homes here heat with fuel oil, so the oil line and tank get checked as part of that work, not just the furnace itself. Once it's connected, the contractor tests ignition, airflow and shutoff safety before calling the job done. Alaska requires the contractor doing this work to be registered with the state.
