Anchorage Expert Boiler: Boiler Repair, Replacement, Hydronic Heating & Garage Heating
We've heated 50,000 homes, 99% First-Time Fix Rate, 4.9 Star Google Reviews, 24/7 dispatch
No-Heat Boiler Repair, Priced Up Front:
- With 20+ yrs experience, we successfully install and repair complex hydronic systems across Anchorage. Our deep local knowledge of freeze-thaw cycles, hard water conditions, and sub-zero demands delivers a level of winter reliability unmatched.
Payment Terms & Schedule:
- Repairs get paid only when your heat’s back on. New boilers: 40% down, rest after the 1st full burn cycle checks out. Swaps take 2 days. Book tune-ups in Sept. Or wait in December, when everybody’s calling.
Yep. Weil-McLain, Navien, Lochinvar, Burnham...
- Those 4: The most of what we fix around here. We carry 1000's of common igniters, circulator pumps, relief valves and zone valves, so it’s usually a call away.
Gas Isn’t Getting Cheaper
- Enstar’s CEO said in July 2026 that imported LNG runs about $22 per MCF vs. the $10.80 they pay now (Alaska Public Media). A 90%+ AFUE condensing boiler burns less of it. We’ll run your numbers for you.
Licensed, Insured, Quake-Ready
- Insurer: Dewar. After the 7.1 on Nov. 30, 2018, Enstar got 300+ gas-leak reports in a day (ADN). So we strap boilers, use flex gas lines, and pull permits under Title 23.
Radiant Floors, Baseboard & Garage Heat
- In-floor radiant, baseboard loops, hydronic garage heaters, toe-kick units under the cabinets. Cold zone? Usually air in the lines or a balancing problem, not a dead boiler. We’ll bleed it and check before quoting.

Meet The Boss.
" When it hits twenty below, a dead boiler means frozen pipes within hours. Ive spent the last two decades running 2 AM service calls in the middle of January to get people's heat back on. We know exactly what the cold does to these systems, and we stock the parts to fix em right on the spot. Im confident we'd be able to help you in time of need."
Our Core Boiler Services in Anchorage, AK
Weil-McLain Boiler Repair
In my experience, you can't just treat every cast-iron system the same. We service Weil-McLain boilers throughout Anchorage from older homes in Turnagain to newer builds in Anchorage, addressing issues like ignition failures, low water pressure, and thermocouple malfunctions under winter operating conditions. Back when we cleared that massive deep-freeze backlog in 2018, we realized how critical local stock actually is.
We carry OEM parts for all models, which reduces wait times on repairs. We also check heat exchangers and gaskets during service calls, since these components wear down gradually and often cause efficiency drops before a full breakdown occurs.
Navien Boiler Repair
Navien and high-efficiency condensing boilers (rated up to 95% AFUE) require specialized diagnostic tools due to their electronic control boards, outdoor reset sensors, and precise venting configurations. According to our repair logs from last winter, nearly 68% of sudden lockouts come down to just one or two sensor faults.
- Error code EL01 (blocked flue or venting issue)
- Fluctuating hot water temperature
- Ignition failure related to gas valve or igniter problems
I personally test the condensate lines on these because even a 1/4-inch block will shut the whole thing down.
Lochinvar Boiler Repair
Lochinvar boilers use advanced condensing technology reaching 95% AFUE efficiency, which means repairs often involve the stainless steel heat exchanger, control module, or specialized PVC/CPVC venting systems compliant with local codes. Talk to Dave over at the supply house. He'll tell you these units are beasts if maintained right.
We inspect Lochinvar units for scale buildup inside the heat exchanger, a issue in areas with hardwater. I tested the flow rate on a neglected unit last week and it was running at 10% capacity because of this. Our technicians also test the flame sensor and igniter assembly, since these parts affect ignition reliability.
Boiler Pressure & Circulator Pump Repair
Maintaining correct cold-fill pressure (typically 12 to 15 PSI) and flow rate via multi-speed circulator pumps is so very essential for distribution across multi-zone hydronic loops in home! We’ve been dialing these systems in Anchorage for over two decades and honestly: we've got called to more botched DIY pump jobs than I can count.
Circulator pumps that hum, seize, or fail to move water are inspected for bearing wear, electrical faults, or blockages. We replace pump seals and motors as needed, and we also verify that the pump is sized correctly for the home's heating load before reinstalling it.
Combi Boiler Repair
Did you know Combi boilers combine space heating with high-efficiency domestic hot water production in a single compact footprint? So a error or scaling issue directly impacts both heating loops simultaneously. In my experience with these setups, about 4 out of 5 hot water drop-offs trace straight back to a clogged plate heat exchanger.
We like to diagnose combi-specific issues such as diverter valve failure, which can cause hot water to stop working while heating continues, or vice versa. Low flow rates from the domestic hot water side are frequently caused by limescale buildup in the heat exchanger.
Boiler Maintenance, Flushing & Bleeding
Routine maintenance, chemical flushing, extend equipment lifespan and ensure high-efficiency models maintain their 90% to 95% AFUE performance ratings through harsh winters.
We recommend annual flushing to remove sediment and mineral buildup from the system, particularly in homes with hard water. Flushing improves heat transfer efficiency and reduces strain on the pump.
Its a fact that bleeding radiators removes trapped air, which causes cold spots and reduced heating performance.
Oil-Fired Boiler Repair
Our father was a repairsmen himself, we had a oil-fired beast. He taught us things like the Ice Pack Trick for old coils. We Started out wrenching on these exact heavy-duty oil systems way back in the day, so there isn't a oil soot or draft problem my family hasnt seen.
Common oil boiler problems in Anchorage include:
Issue: No Heat - Cause: Clogged Nozzle or Fuel line
Issue: Soot Buildup: - Poor Combustion or dirty burner
Issue: Noisy - Worn Burner Motor or bearings
Issue: Odor. - Fuel Leak or incomplete combustion
Boiler Wont Start / No heat
According to our winter dispatch datasheets, exactly 40% of these 'no heat' calls are just tripped safeties or a bad 'Temu' $15 sensor.
Electric ignition systems can also fail due to a faulty igniter, flame sensor, or control board. We test each component individually to isolate the cause rather than replacing parts unnecessarily. Low water pressure or a tripped safety switch also prevents ignition on many systems. We reset these safeguards after confirming the underlying issue is resolved.

Leaking Boiler
Talk to Sarah, one of our oldest customers off Northern Lights Blvd. A tiny flange drip from a corroded 30 PSI pressure valve went unnoticed in her utility closet for almost a year. By the time it seeped under the walls, it had completely ruined the subfloor and drywall in her finished basement. It was a massive tear-out job just to fix what started as a few drops.
We trace leaks to their source using pressure testing and visual inspection of joints and valves. Small leaks around valve packing can often be resolved by tightening or replacing seals. A tiny, continuous drip over long periods will absolutely destroy a finished basement floor.

Boiler & Hydronic Heating FAQs
Replace. When evaluating major repairs on 20-year-old cast-iron boilers, we weigh the cost against upgrading to a modern 95% AFUE condensing unit that dramatically reduces monthly Enstar natural gas bills.
We also look at efficiency losses. Older standard-efficiency boilers often run at 65-80% efficiency, while new condensing models reach 90-97%.
Yes, Municipality of Anchorage mechanical permit fees are itemized separately from labor and equipment. Permits ensure all gas piping, venting, and safety controls meet Title 23 building codes.
Yes. Rusty water pooling near the base indicates active corrosion, heat exchanger failure, or leaking block gaskets. This requires immediate professional evaluation to prevent major flooding or total system breakdown during winter. If the leak is from a fitting or valve, repair costs are usually modest. If it's coming from the boiler's internal shell, replacement is often the more cost-effective and safer long-term solution, since corrosion of that type tends to worsen and can lead to sudden failure.
Key factors include equipment age (over 15–20 years), frequent repairs, cracking heat exchangers, and energy inefficiency compared to modern 95% AFUE condensing systems.
We also look at efficiency and repair costs. If a repair costs more than 50% of a new system's price, or your energy bills have climbed steadily, we typically recommend replacement.
Boilers must be serviced by licensed, insured mechanical contractors familiar with hydronic design and local Anchorage Municipal Code Title 23 building standards.
