Boiler repair still comes up at higher elevations, where winter nights drop well below freezing, and in custom homes built with radiant floor heat under tile or concrete. Combi boilers show up in those homes too. Hard water is the common enemy, scaling the plate heat exchanger on a combi and the heat exchanger on condensing units. Reliable Boiler Service connects Arizona homeowners with technicians for radiant floor boiler repair, zone valve replacement and combi boiler installation. Call (866) 456-6311.

Why choose us for boiler repair

Arizona Locals Choose Us for Boiler Repair

Radiant floor and combi boiler owners in Arizona often find most HVAC companies only work on heat pumps. Call (866) 456-6311 and get matched with a technician who services hydronic equipment.

Hard water is the problem we hear about most here. Scale on a combi's plate heat exchanger shows up as hot water that swings between hot and cold. A descale or a scale filter on the cold supply fixes many of those calls. Boiler repair and combi boiler installation are booked after the job is talked through.

Boiler Repair FAQs

Frequently asked questions about boiler repair

Common questions about boiler repair in Arizona, answered plainly.

Talk to a real person

What pressure should my boiler run at in Arizona?

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.

Should I repair or replace my boiler?

Repair makes sense for parts like igniters, circulators and zone valves. A cracked section, a leaking heat exchanger or a boiler where parts are no longer made usually points to replacement.

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.

Are there rebates for high-efficiency boilers?

Many gas utilities and state energy programs offer rebates on qualifying condensing boilers. Terms change often, so check your utility's current program before you buy.
