Same-day boiler repair across the Denver metro
We’re open Monday through Sunday, 7am to 9pm, and we can often be at your door the same day you call. Sometimes within one to two hours, even for work that isn’t an emergency.
Every job starts with upfront pricing. You know the number before we start, and there are no hidden fees on the invoice afterward. Every repair is backed by our 100% satisfaction guarantee.
24/7 emergency boiler repair
A boiler that fails during a hard freeze isn’t only a comfort problem. Hydronic lines can drop below freezing within hours once the heat is off, and a frozen line often becomes a burst line the moment things thaw.
That’s why we treat a boiler emergency as a safety call, not a routine service call. We offer 24/7 emergency availability year-round, and before anyone arrives you’ll get a text with your technician’s name and expected arrival time. No wondering who’s coming or when.
If the failure also involves standing water, a flooded mechanical room, or a shut-off valve that won’t hold, our emergency plumbing team works alongside our heating technicians on the same visit.
Common boiler problems we repair
On the residential side, most of our calls come down to a handful of failures. No-ignition faults and pilot light failure on older units. Low water pressure, kettling from scale on the heat exchanger, and zone valve failures that leave one part of the house cold while another stays comfortable.
Waterlogged expansion tanks and cracked heat exchangers show up on aging systems. Commercial buildings add burner tuning problems, pressure and relief valve issues, and circulator failures on larger loops.
We work on all makes and models, and we diagnose in a set order so you understand what we find and why it matters. If the trouble turns out to be your furnace or heat pump instead, our heating repair technicians handle those systems too.
Signs your boiler needs service
Ceiling stains between floors, pressure that drops across multiple fixtures, and water anywhere near electrical or inventory all mean something is failing upstream. A burst line in a commercial building can take a floor or a kitchen out of service in minutes. Waiting turns a repair into water damage, remediation, and days of lost use. We treat commercial leak calls with the urgency they actually carry.
What happens when a boiler problem gets ignored
A pressure relief valve that drips today is a flooded utility room and a warped subfloor later. A failing circulator pump makes the heat exchanger overheat, and once that cracks, you're buying a boiler instead of a repair. A blocked or damaged flue can push carbon monoxide into the living space, which turns a comfort issue into an emergency. Keep a working CO detector near any gas-fired equipment. None of these problems fix themselves, and all of them get more expensive the longer they sit.
Residential and commercial boiler service
Boilers aren’t only a winter concern. Commercial boilers run year-round because they serve domestic hot water for the building, not just space heating, which is why property managers, dental offices, restaurants, HOAs, and apartment complexes need someone they can call in July as easily as in January.
Residential boiler service covers everything from a single-family hydronic system to a basement in-floor loop or baseboard heat. Same-day dispatch is available for both, across our full Denver metro service areas: Denver, Arvada, Aurora, Broomfield, Commerce City, Lakewood, Thornton, and Westminster.
Annual boiler service and maintenance
Most expensive winter breakdowns get prevented in the fall. During a tune-up we check seals, expansion tank pressure, and the relief valve, then clean the combustion side of the burner and anything that built up scale or soot over the season. Denver's freeze-thaw swings are hard on equipment that sits idle half the year, so the fall visit matters more here than it does in milder climates. Consistent service means fewer surprise failures and a longer life for the boiler you already own. The simplest way to never miss one is our Total Home Care Club, which builds annual heating service into a membership along with priority scheduling and exclusive member discounts. Schedule boiler service today.
What you can do between visits
Watch the pressure gauge and make sure it stays in the manufacturer's recommended range. Check around fittings and the base of the unit for leaks, and keep the area clear so combustion air isn't restricted. Pay attention to the expansion tank. If it feels heavy when you tap it, or pressure spikes as the system heats up, it's time to call someone.
When to repair a boiler and when to replace it
At some point every boiler crosses the line from worth repairing to worth replacing, and we’ll tell you honestly which side of that line yours is on. It usually comes down to the age of the unit, how efficiently it’s running, and whether the repair cost is starting to approach what a new system would cost.
If a repair still makes sense, that’s what we recommend. If it doesn’t, we’ll walk you through boiler installation and replacement options, including high-efficiency condensing models. Either way you get straight information and a price before we start. No upselling, no pressure.
Why Denver calls Prime for boiler work
Boiler work is code-driven, gas-fired, and pressurized, which is why it belongs with a licensed crew. Nathan Padilla founded Prime in 2012 and has more than 27 years in the trades. He earned his Colorado Master Plumber license in 2007 and holds an ICC National Standard Master Mechanical certification, earned in 2013, the credential covering HVAC, boilers, and mechanical systems.
Prime holds Colorado Plumbing License #PC3045 and has completed an estimated 15,000 to 20,000 jobs since opening. We’re a family-owned Denver company, not a franchise, which means Nathan’s name is on the work and the accountability is his.
If a repair is a larger expense than you planned for, we offer flexible financing through GoodLeap so a cold weekend doesn’t turn into a cold month.
Frequently asked questions
Watch for leaking water around the unit, foul odors, heat that's delayed or never quite arrives, banging or whistling pipes, and a boiler that cycles on and off constantly. Any of those is worth having looked at before it turns into a no-heat call.
Often the same day, and sometimes within one to two hours of your call. We also offer 24/7 emergency availability year-round for no-heat and active-leak situations. Call us and we'll tell you exactly when we can be there.
Yes. We handle burner tuning, pressure and relief valve issues, and circulator failures for restaurants, dental offices, apartment complexes, HOAs, and other commercial buildings across the metro. Commercial boilers run year-round for domestic hot water, so we take those calls in every season.
It depends on the issue, the part, and the age and type of your system. What doesn't change is how we quote it. You get upfront pricing before any work begins, and financing is available if the number is more than you planned for.
We work on all makes and models, including cast iron, wall-hung, and high-efficiency condensing boilers, on both hot water and hydronic floor systems.
We serve Denver, Arvada, Aurora, Broomfield, Commerce City, Lakewood, Thornton, and Westminster from our Denver location at 7000 Broadway Suite 205.
Get everyone out of the area first. If you smell gas or suspect carbon monoxide, leave the building and call 911 or your gas utility from outside before doing anything else. Once everyone is safe, call us at (720) 542-8153.
