Quick Facts

What Are the Most Common Furnace Problems in Alaskan Homes?

In Anchorage and the Mat-Su Valley, a heating season that runs from September through April puts furnaces under sustained load. The issues we see most often are tied directly to that demand: cracked heat exchangers from years of expansion and contraction, blower motors that wear out after running thousands of hours, failed hot-surface igniters, dirty flame sensors that cause short cycling, and gas pressure problems that trigger lockouts on the coldest nights.

A handful of those failures are safety issues, a cracked heat exchanger can leak carbon monoxide, which is why our 21-point HVAC inspection walks the equipment top to bottom rather than just clearing the immediate fault.

How Do You Know When to Repair vs. Replace Your Furnace?

There’s no single right answer, but a few signals matter. Age is the first: most gas furnaces in Alaska last 15–20 years, and repairs on a 17-year-old unit rarely pay back the way they would on a 7-year-old one. Frequency is the second, if you’ve called for service three winters in a row, the equipment is telling you something. Energy bills creeping up without a rate increase, uneven heating between rooms, and a low AFUE (Annual Fuel Utilization Efficiency) rating compared to today’s 95%+ units all point toward replacement.

We give you the honest read, not a sales pitch. If a repair will get you through another five winters, we’ll say so.

What Does Furnace Repair or Replacement Cost in Anchorage?

Furnace pricing in Alaska depends on the size of your home, the efficiency rating you choose, fuel type (natural gas vs. propane vs. oil), and whether ductwork or venting needs modification. A simple repair like an igniter or flame sensor is modest; a full high-efficiency replacement with new venting is a larger investment. We don’t quote sight-unseen, every estimate is based on a tech actually looking at your system.

Gas Furnace vs. Heat Pump, Which Is Right for Alaska?

In most of Southcentral Alaska, a high-efficiency natural gas furnace is still the workhorse. Gas heats fast, handles below-zero temperatures without losing capacity, and runs on infrastructure that’s stable when the power goes out (with the right setup). Heat pumps, including cold-climate models, are improving and can make sense as a supplemental system, especially for homes that also want cooling in summer, but most lose meaningful capacity below 0°F.

The right answer depends on your home’s envelope, your fuel availability, and how you want to use the equipment. Our techs walk through both options with you and recommend what actually fits.

What Happens During a Moore Heating Furnace Tune-Up?

Our 21-point inspection is the same checklist on every visit:

Inspect heat exchanger for cracks and corrosion
Check and clean the burner assembly
Test and clean the flame sensor
Inspect the hot-surface igniter
Verify gas pressure (inlet and manifold)
Test the inducer motor and pressure switch
Inspect and lubricate the blower motor
Measure blower amp draw against spec
Replace or recommend a new air filter
Check belt tension and condition (if applicable)
Test all safety controls and limit switches
Inspect venting and combustion air supply
Check for carbon monoxide at the supply register
Verify thermostat calibration and operation
Test heat anticipator settings
Inspect electrical connections and tighten as needed
Check capacitor and contactor condition
Measure temperature rise across the heat exchanger
Inspect ductwork at the furnace for leaks
Test system through a full heating cycle
Review findings with you and document the visit

Frequently Asked Questions

How much does a furnace tune-up cost in Anchorage?

Furnace tune-up pricing depends on the type of system and whether you’re on a maintenance plan. Members of our 15-5 Preventative Maintenance Agreement receive priority scheduling and discounted rates. Call (907) 561-1500 for current pricing.

How long does a new furnace installation take?

Most residential furnace replacements take one day. More complex jobs, a fuel conversion, new venting, or ductwork modifications, may take two days. Your technician will give you a clear timeline before any work starts.

What should I do if my furnace stops working in winter?

First, check that the thermostat is on, set above the room temperature, and has working batteries. Confirm the breaker hasn’t tripped and the furnace switch is on. If those check out and the furnace still won’t fire, call (907) 561-1500, we answer 24/7. In an Alaskan winter, a long no-heat period risks frozen pipes, so don’t wait it out.

How often should I service my furnace?

Annually, ideally in early fall before the heating season ramps up. A yearly tune-up catches small issues before they become midnight emergencies and keeps manufacturer warranties valid on most equipment.

Do you service all furnace brands?

Yes. We’re a Lennox Premier Dealer and we install Lennox and Aire-Flo equipment, but our techs are trained to repair every major furnace brand sold in Alaska. We’ll service the equipment you have regardless of who installed it.

Is it worth upgrading to a high-efficiency furnace in Alaska?

For most Anchorage and Mat-Su homes that heat eight months a year, a high-efficiency (95%+ AFUE) furnace pays back faster than in milder climates because the equipment runs so many hours. Your tech can walk through expected savings based on your current system and fuel rates.
