When your boiler stops working in the middle of a Colorado winter, you need a technician who knows boiler systems — not a general HVAC crew treating it as an afterthought. A Clear Choice Plumbing and Heating provides expert boiler repair in Englewood CO for residential and light commercial systems. We diagnose quickly, carry common parts, and restore your heat with upfront pricing and no surprises.
Englewood’s housing stock is older than most nearby communities, and many pre-1970 homes still rely on cast iron boiler systems with radiator networks. These systems are highly durable — often lasting 40 to 60 years — but they require specialized expertise in hydronic heating rather than standard forced-air HVAC knowledge.
At A Clear Choice Plumbing and Heating, boiler systems are a core focus. We service everything from traditional cast iron boilers to modern condensing units, combination boiler-water heaters, and radiant floor systems. Whether your boiler has stopped working, is making unusual noises, short cycling, or hasn’t been serviced in years, our team provides accurate diagnostics and reliable repairs.
Front Range winters can drop well below zero, making a boiler failure more than just inconvenient — it can lead to frozen pipes and serious property damage. That’s why we treat boiler service calls as a priority, especially during peak heating season.
Boiler stopped working — no heat: Likely causes include ignition failure, thermostat issues, loss of pilot light, or pressure lockout. We diagnose the exact failure and restore system operation.
Boiler making gurgling sounds: Indicates air trapped in the system. Radiators need bleeding, and the circulator pump may also be affected.
Pressure gauge too high or too low: Could indicate expansion tank failure, water loss from a system leak, or a faulty pressure relief valve.
Radiators cold at top, warm at bottom: Caused by an air lock in the radiator. Bleeding is required, and if unresolved, a failing zone valve or circulator may be the issue.
Boiler making banging or kettling noise: Caused by limescale buildup on the heat exchanger, leading to localized boiling. This is common in older systems, reduces efficiency, and can cause long-term damage.
Short-cycling — turning on and off frequently: May result from an oversized system, failing thermostat, low pressure, or a blocked condensate line in condensing boilers.
Yellow or orange pilot flame (should be blue): Signals incomplete combustion and a serious carbon monoxide risk. Leave the property immediately, call 911, then contact us.
Boiler leaking water: May result from a failed pump seal, pressure relief valve discharge, or corroded fittings. Requires immediate attention to prevent further damage.

We diagnose and repair all types of residential and light commercial boiler systems — including Weil-McLain, Burnham, Peerless, Navien, Bosch, Lochinvar, and others. Whether the failure is in the ignition system, gas valve, circulator pump, expansion tank, pressure relief valve, or heat exchanger — we identify the exact problem and repair it correctly.
Annual boiler maintenance in Englewood is the single most effective way to prevent mid-winter breakdowns and maintain heating efficiency. A neglected boiler can lose 10–15% efficiency annually. Our service includes: combustion analysis and burner adjustment, heat exchanger inspection and cleaning, flue and venting inspection, circulator pump check, expansion tank pressure test, pressure relief valve test, all controls and safety devices check, and system pressure and flow verification.
Cast iron radiator systems common in older Englewood homes require periodic bleeding to remove trapped air, balancing to ensure even heat distribution between rooms, and inspection of zone valves and thermostatic radiator valves. We service the full hydronic system — not just the boiler unit itself.
When repair is no longer cost-effective — typically when the boiler is over 20 years old, has a cracked heat exchanger, or faces repair costs exceeding 50% of replacement cost — we provide boiler replacement with high-efficiency condensing units that deliver significant long-term energy savings.

We provide boiler repair and annual service throughout Englewood’s neighborhoods:
Check the thermostat (set to heat and above room temp), system pressure (12–15 psi), circuit breaker, and pilot light (older units). If the issue persists or you see an error code, schedule a diagnostic.
Usually caused by limescale buildup on the heat exchanger. It reduces efficiency and causes overheating. A system flush typically fixes early-stage issues.
Yes. It usually means the wax ring has failed, allowing wastewater to seep into the subfloor, which can cause rot and expensive structural damage if not fixed quickly.
Most repairs cost $200–$600. Minor parts fall within this range; major components like a heat exchanger can cost significantly more.
Typically $150–$250 per year. Includes inspection, cleaning, safety checks, and efficiency testing.
Gurgling usually means trapped air in the system. Bleeding radiators fixes it. If it returns, there may be a leak.
Replace if it’s 20+ years old, has a failed heat exchanger, repair costs exceed 40–50% of replacement, or efficiency is very low.
