Boiler Services — Repair, Installation & Replacement
Boilers are what Parker Boiler & HVAC is built around. While most HVAC shops treat boilers as a sideline, they're the core of our trade — steam, hot-water, and hydronic systems serviced, repaired, installed, and replaced across Parker and the south Denver metro, residential and commercial.
Call 303-944-3704 for 24/7 emergency boiler service, or schedule below. Nine years in business, 26+ years of combined experience, and trucks stocked with the circulator pumps, zone valves, and gas valves boilers actually fail on.
Boiler repair
No heat, leaking water, low pressure, kettling noises, one cold zone while the rest of the house is warm — these are the calls we run every winter day. We diagnose the actual fault: circulator pumps, zone valves, air in the loops, pressure problems, failed gas valves, and control faults. Repair means fixing the real problem, not resetting a switch and leaving.

Boiler installation & replacement
When a boiler reaches the end of its life, the replacement matters more than the equipment spec sheet: right-sizing for the building's actual heat load, correct piping and venting, and combustion tuning for our elevation — work that determines whether a new boiler runs efficiently for 20 years or struggles from day one. We install residential and commercial boilers throughout the south metro.
Hydronic & radiant specialists
Zoned hydronic systems, radiant floor heating, and multi-circulator setups are the systems we're known for — the custom-home and commercial work generalists pass on. Circulator pump repair, zone valve replacement, manifold diagnostics, and loop balancing are routine work for our senior techs.
Commercial boiler service
Boiler plants in office buildings, apartments, and retail spaces run on maintenance schedules and documented service. We provide scheduled commercial boiler maintenance, emergency response, and replacement planning for building owners and property managers — including after-hours work that keeps tenants comfortable and leases intact.
Preventive boiler maintenance
Boilers reward maintenance more than almost any equipment: annual combustion checks, low-water cutoff testing, and cleaning prevent most mid-winter failures. Our maintenance plan members get priority response when cold snaps hit and every tech's calendar fills.

Straight answers, licensed techs, and a phone that gets answered — 24/7 for emergencies.
Call 303-944-3704Questions we hear every week
What boiler types do you work on?
We service all major residential and commercial boiler types — cast-iron and steel hot-water boilers, steam systems, high-efficiency condensing boilers, and the circulators, zone valves, and controls attached to them.
Should I repair or replace my boiler?
It depends on the failure and the boiler's condition. We diagnose first, then give you honest numbers on repair versus replacement — we don't steer jobs toward the bigger invoice.
Do you install boilers, not just repair them?
Yes — for both residential and commercial installations, including combustion tuning for Front Range altitude, which many installers skip.
Do you service commercial boiler plants?
Yes — boiler plants in office buildings, apartments, and retail spaces are a core part of our work, including after-hours service.
