About Reliable Boiler Service

Boiler Repair Company in Colorado Near Me

Colorado has plenty of hydronic heat, especially radiant floors and baseboard in mountain homes, where cold nights run deep into spring.

Altitude is the detail that catches people out. Gas boilers lose capacity as the air thins, and most manufacturers require the unit to be derated or set up for high altitude above a certain elevation. A boiler set up for sea level can burn rich and soot up. Reliable Boiler Service connects Colorado homeowners with technicians for boiler repair, combustion tuning on annual boiler tune-ups, and boiler installation set up correctly for elevation. Propane boilers in rural areas are part of the work too. Call (866) 456-6311.

Boiler Repair FAQs

Frequently asked questions about boiler repair

Common questions about boiler repair in Colorado, answered plainly.

Talk to a real person

What pressure should my boiler run at in Colorado?

Most residential hot water boilers sit around 12 to 15 psi when cold and stay under 30 psi when hot. Steam boilers are different and run at a fraction of a pound.

Do condensing boilers work with old cast iron radiators?

They can, but they only condense when return water comes back cool. Outdoor reset control and properly sized radiators make the difference.

Why are my radiators cold at the top?

Air is trapped in them. Bleed each radiator with a radiator key until water runs steadily, then check the boiler pressure and top it up if needed.

What does a lockout code on my boiler mean?

The boiler tried to light several times and failed, so it shut itself off for safety. Note the code before resetting, since it narrows the cause down to ignition, flame sensing, venting or water pressure.

What should I do if my boiler is leaking?

Turn the boiler off, close the fill valve if water keeps spreading, and call (866) 456-6311. Note where the water is coming from, since that decides between a repair and a replacement.
