Englewood’s housing stock is older than most surrounding communities, and a significant share of its pre-1970 homes were originally heated with cast iron boiler systems connected to radiator networks. These systems are durable — many have been operating for 40 to 60 years — but they require a technician who understands hydronic heating, not just forced-air HVAC.
At A Clear Choice Plumbing and Heating, boiler systems are part of our core expertise. We service cast iron boilers, modern condensing boilers, combination boiler-water heater units, and radiant floor heating systems. Whether your boiler has stopped working entirely, is making unusual noises, is cycling on and off too frequently, or simply hasn’t been serviced in several years — we provide the diagnosis and repair your system needs.
Front Range winters regularly push temperatures below zero, and a boiler failure during a cold snap isn’t just uncomfortable — it creates real risk of frozen pipes throughout the home. We treat boiler calls as priority service, especially during the heating season.
Boiler stopped working — no heat: Ignition failure, thermostat issue, loss of pilot light, or pressure lockout. We diagnose the specific failure and restore operation.
Boiler making gurgling soundsAir trapped in the system. Radiators need bleeding; circulator pump may also be affected.
Pressure gauge too high or too low: Expansion tank failure, water loss from a system leak, or a failed pressure relief valve.
Radiators cold at top, warm at bottom: Air lock in the radiator needs bleeding. If bleeding doesn't resolve it, zone valve or circulator may be failing.
Boiler making banging or kettling noise: Limescale buildup on heat exchanger causing localized boiling common in older systems. Reduces efficiency and causes damage.
Short-cycling — turning on and off frequently Oversized system, failing thermostat, low pressure, or a blocked condensate line on a condensing boiler.
Yellow or orange pilot flame : Incomplete combustion — carbon monoxide risk. Leave property, call 911, then call us @ (720)-938-1554
Boiler leaking water: Failed pump seal, pressure relief valve discharge, or corroded fitting. Requires prompt attention or call us @ (720)-938-1554
Safety Note: If you smell gas near your boiler or suspect carbon monoxide (yellow flame, CO alarm activation, unexplained headaches), leave the property immediately and call 911 before calling us.
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.

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.
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.
