Straight answers to the questions homeowners actually ask us — from kettling boilers to short-cycling furnaces. Every answer links to the service page where we fix that exact problem.
A boiler making banging, kettling, or gurgling noises usually has mineral scale on the heat exchanger or trapped air in the loops. Both are fixable — a flush or a chemical descale restores quiet operation. Persistent kettling on an older unit can also signal a failing circulator. Our boiler services team diagnoses the sound before it becomes a shutdown.
Boiler pressure that drops between fillings points to a slow leak — most often the expansion tank, the pressure-relief valve, or a hidden fitting in the loop. If you're re-pressurizing weekly, the system is telling you something. Catching it early is the difference between a part and a repipe; see our boiler repair page for what a diagnosis covers.
A furnace that starts, runs a few minutes, and shuts off is short-cycling — usually a dirty flame sensor, a clogged filter choking airflow, or an overheating limit switch tripping. All three are routine repairs. If it happens every cycle, schedule heating service before the heat exchanger is stressed.
Uneven heat almost always traces to air in the radiators, a stuck zone valve, or an unbalanced circulator — not the boiler itself. Bleeding radiators helps, but recurring cold zones on one side of the house point to a zone-control issue we repair regularly.
An AC that runs but blows warm air is usually low refrigerant from a leak, a failed capacitor, or a dirty condenser coil unable to shed heat. Running it low on refrigerant damages the compressor, so shut it off and book air-conditioning repair rather than letting it grind.
Ice on the refrigerant line or indoor coil means the coil is starving for airflow (dirty filter, blocked return) or the system is low on refrigerant. Turn the system off and let it thaw — running it frozen can crack the coil. We find the cause, not just the ice.
Annually, before the heating season. A pre-winter tune-up cleans the combustion side, tests safety controls, and catches the worn parts that fail during the first cold snap. Plan members get priority scheduling when every tech's calendar fills — see our maintenance plans.
Most boilers serve 15 to 20 years with consistent maintenance; furnaces run 15 to 18. The repair-or-replace call comes down to age, repair history, and efficiency — a well-maintained 15-year-old system is often worth repairing, while a 25-year-old unit with a cracked heat exchanger isn't safe to repair.
Yes — nights, weekends, and holidays, with a real person on the phone at 303-944-3704. No-heat calls in freezing weather are our top dispatch priority across the service area.
We're based in Parker and cover Douglas County and the south Denver metro — Castle Rock, Centennial, Aurora, Highlands Ranch, Littleton, and more. Most in-town calls get same-day or next-day appointments. The full list of communities is on our service areas page.
Yes — primarily residential, with selective commercial boiler service available through the same crew. If your building has a commercial boiler plant along a Parker Road or business-park corridor, call and we'll tell you straight whether we're the right fit.
