Have No Heat In Your House or a Frozen Pipe Right Now?
At 0°F to -25°F in Alaska, an unheated house can suffer frozen and split baseboard or domestic water lines within 4 hours. We stock Taco/Grundfos circulator pumps, Honeywell zone valves, igniters, and flameless electronic pipe-thawing equipment on our trucks.
Common Alaska Heating & Boiler Symptoms We Fix
Quick diagnostic reference for Weil-McLain, Burnham, Navien, Lochinvar, and forced-air systems:
| Symptom | Probable Cause | Immediate Action |
|---|---|---|
| Thermostat is set to HEAT (70°F+), but boiler or furnace makes zero sound | Tripped breaker, flipped red emergency shutoff switch, dead thermostat batteries, or tripped high-limit aquastat / rollout safety switch. | Check the red emergency toggle switch near the stairs/boiler room and check your breaker panel. Do not repeatedly press reset more than once. |
| Boiler burner fires and gets hot, but baseboards / radiators stay ice cold upstairs | Seized circulator pump (Taco/Grundfos), failed zone valve actuator (Honeywell), airbound hydronic loop, or slush/ice blockage in an exterior wall pipe. | Open cabinet doors, place safe electric space heaters near cold exterior walls, and call (907) 250-9156 immediately before the frozen loop splits. |
| Boiler pressure gauge reads 0 PSI (or below 8 PSI) and system won't circulate | Failed pressure-reducing auto-fill valve, hidden hydronic leak in crawlspace/slab, or airlock preventing hot water from reaching upper floors. | Do NOT feed cold water into a scorching-hot cast iron boiler (thermal shock can crack the heat exchanger). Call a technician to safely pressurize and bleed zones. |
| Boiler pressure exceeds 28–30 PSI and water is pooling from the relief pipe | Waterlogged expansion tank (bladder ruptured) or stuck-open water feed valve continuously over-pressurizing the closed loop. | Shut off the manual water supply valve feeding the boiler if water is actively discharging, and schedule expansion tank & relief valve replacement. |

Boiler, Furnace & Hydronic Repair Questions & Direct Answers
Straightforward answers regarding boiler, furnace & hydronic repair diagnostics, pricing, and scheduling across Anchorage and the Mat-Su Valley.
We diagnose, repair, and install all major residential and commercial heating systems in Alaska, including Weil-McLain, Burnham, Navien, Lochinvar, Triangle Tube, Viessmann, Carrier, Bryant, Lennox, Goodman, and Toyotomi/Rinnai heaters. Call (907) 250-9156.
When the boiler burner runs and temperature gauge reads 180°F, but a zone remains cold, the culprit is usually a failed zone valve motor, a seized circulator pump, an airlock in the hydronic loop, or a frozen section of baseboard pipe along an exterior wall. Call (907) 250-9156 before the stagnant zone freezes solid.
Hydronic heating glycol should be tested every 1–2 years before winter to ensure freeze protection down to at least -30°F and proper pH levels (8.0–9.5) so acidic degraded glycol doesn't corrode your heat exchanger, pumps, and air vents. Call (907) 250-9156 for a boiler tune-up and glycol test.
