Emergency Boiler Thawing & Heating Repair
When temperatures plunge below zero in Anchorage and the Mat-Su Valley, a cold boiler isn't just an inconvenience—it's an active threat to your property's plumbing lines. Our certified heating crew is on call 24 hours a day.
What to do right now while waiting for dispatch:
Follow these steps immediately to safeguard your water pipes from freezing solid.
Open Sink Cabinets
Open all cabinet doors under sinks on exterior walls so residual room warmth circulates around piping.
Slow Drip Faucets
Allow a pencil-thin stream of water to run on the faucet farthest from your main water shutoff to maintain flow.
Avoid Open Flames
Never use blowtorches or propane heaters on frozen copper lines. Use safe ceramic space heaters or electric warmers.

Boiler & Heating Emergencies We Resolve

Frozen Hydronic Baseboard Loops
We thaw frozen heating lines using specialized electric and low-pressure steam equipment without torch hazards.
Boiler Burner & Thermocouple Lockouts
Troubleshooting spark igniters, flame sensors, gas valves, and aquastats across Weil-McLain, Burnham, and Navien units.
Circulator Pump Replacements
When the circulator motor seizes and hot water cannot move through zones, we carry replacement Taco and Grundfos pumps on our trucks.
Expansion Tank & Relief Valve Leaks
Waterlogged expansion tanks causing pressure relief valves to discharge scalding water onto the floor.

Emergency Glycol Flush & Refill

If the boiler does not click or fire at all, it may be an electrical interlock, low water cutoff, or fuel supply issue. Call (907) 250-9156 for immediate diagnostics.
