Keep your home warm with reliable boiler and radiant heat service — expert repair, maintenance, and replacement across Elizabeth and the Denver metro.
If you're noticing any of these common warning signs, your heating system may be struggling to operate safely and efficiently.
Your system fails to produce heat or there is no hot water available when needed.
Radiators or baseboards that stay cold, have cold spots, or heat your home unevenly.
Loud banging, gurgling, or kettling noises coming from the boiler while it runs.
Water visibly leaking or pooling around the base of the heating unit.
Low boiler pressure on the gauge, or a system that is constantly losing pressure.
An older boiler unit that is increasingly requiring frequent, costly repairs.
A boiler that's leaking, won't hold pressure, or makes loud knocking sounds needs a professional look before a small issue becomes a cold house.
Diagnosing and fixing leaks, pressure problems, faulty valves, thermostats, and circulation issues.
Annual service and tune-ups to keep your heating system efficient, safe, and running reliably through winter.
Helping you choose and install the right gas, electric, or high-efficiency system for your home.
Clearing sludge and buildup that cause cold spots and reduce your overall heating efficiency.
Boilers are workhorses, and many Elizabeth-area homes rely on them for steady, comfortable radiant heat. But they run hard through Colorado's long winter. An annual service checks system pressure, inspects for leaks, tests safety controls, bleeds radiators, and clears sludge buildup, keeping your heat even, your bills lower, and your system running for years. The best time to service a boiler is before the heating season, not in the middle of a January cold snap.

We recommend an annual tune-up, ideally before the winter chill sets in here in Colorado. Regular maintenance keeps it running efficiently, catches small leaks or pressure issues early, and extends the lifespan of your system.
If your boiler is relatively new and the repair is minor, fixing it is the way to go. But if it's over 15 years old, constantly breaking down, or the repair cost is high, it might be more cost-effective to replace it with a modern, high-efficiency model.
This often means air is trapped in the system, preventing hot water from circulating. Usually, bleeding the radiators will solve the problem. If it doesn't, there might be an issue with the circulator pump or sludge buildup.
Kettling sounds like a boiling kettle and is typically caused by limescale or sludge buildup in the heat exchanger, which restricts water flow and causes the water to boil. It's a sign your system needs a flush and cleaning to prevent damage.
With proper installation and annual maintenance, a quality cast-iron boiler can last 15 to 20 years or more. High-efficiency condensing boilers typically last around 15 years. Keeping up with regular service is the best way to maximize its lifespan.
