A boiler down in a Colorado January is an emergency, not an inconvenience — and Parker Boiler & HVAC treats it that way.

The failures we fix every winter day
No heat: failed igniters, gas valves, and pressure switches; control and thermostat faults. Water problems: leaks, pressure loss, and expansion tank failures. Comfort problems: stuck zone valves and failed circulator pumps leaving rooms cold while the boiler runs. Noise problems: kettling and banging from scale or air in the system. We stock the parts these failures need, so most repairs are finished on the first visit.
Diagnosis before parts
Boiler repair done badly looks like this: reset the boiler, leave, repeat next week. We test combustion, check water pressure and flow, verify each zone, and isolate the actual fault before quoting work — because a misdiagnosed boiler problem costs you twice. If a repair doesn't make economic sense against replacement, we'll tell you that straight, with numbers.
Commercial boiler repair
Boiler plants serving offices, apartments, and retail spaces get priority emergency response — downtime affects tenants and leases. We repair commercial boilers, coordinate retubes, and provide after-hours service windows so buildings stay warm and businesses keep running.
Why boilers fail in this climate
Front Range winters are hard on boilers: sub-zero snaps in December and January, long heating seasons at elevation, and summer idle periods that let zone valves stick and seals dry out. Annual maintenance prevents most of it — but when something does fail, we're the crew that answers.

Questions we hear every week
How fast can you get here for a no-heat emergency?
No-heat calls are our top priority and get dispatched around the clock. From our Parker shop, most emergency calls get a tech within hours.
What boiler problems do you fix most often?
The most common are failed igniters and pressure switches, stuck zone valves, circulator pump failures, air-bound loops, low water pressure, and control faults. Most are repairable same visit with our stocked trucks.
What should I do while waiting for the tech?
Shut the boiler off if it's leaking heavily, check that the thermostat is calling for heat, and check the pressure gauge — then call us. Don't keep resetting it; repeated lockouts usually mean a real fault.
Is an old boiler worth repairing?
If it's in good condition, absolutely — boilers routinely run 20–30 years with proper care. We assess honestly and repair what makes sense rather than steering you to replacement.
