Huntsville, AL Boiler Repair and Maintenance Specialists

Boilers are the quiet minority in north Alabama heating, which is exactly why a homeowner with one has trouble finding a company that still works on them. Corbin’s Air, Water & Power Solutions, Inc has serviced hydronic systems since 1935, and our technicians handle boiler repair Huntsville AL property owners need on radiators, baseboard loops and radiant zones from the Whitesburg Drive branch. We cover Madison County, Madison, Owens Cross Roads, and the surrounding Tennessee Valley. A live person answers around the clock, boiler maintenance service quotes are free, the work is licensed under HVAC 1992263, and we have been a family-owned BBB member for 90 years.

If the boiler also feeds your domestic hot water, our Plumbing page shows the licensed plumbing work our crews combine with hydronic service on a single visit.

Boiler Symptoms That Call For A Technician Today

Hydronic systems tend to fail gradually, then all at once. Most of the calls we run start with something the homeowner had noticed for a week and hoped would settle down.

Symptoms that deserve same-day attention:

• No heat at all, or a boiler that fires and immediately locks out
• Visible water on the floor beneath the boiler or near the pump
• Steam or a hissing relief valve
• A gas odor anywhere in the mechanical room
• Pressure reading well above or below the normal band

No Heat Or Lukewarm Radiators And Baseboards

When some emitters warm up, and others stay cool, the problem is usually distribution rather than the burner: trapped air in a high loop, a stuck zone valve, or a circulator that spins without moving water. We isolate each zone and test rather than guessing.

Kettling, Banging And Gurgling Sounds

Kettling is the sound of water flashing to steam against scaled heat exchanger surfaces. Banging in the pipes often means air or a rapid valve closure, and gurgling almost always means the system needs bleeding and a proper fill. Each has a different fix, and none of them improve on their own.

Leaks Around Fittings, Valves And The Relief Valve

A weeping fitting is more than a puddle. Every drop is replaced by fresh water carrying minerals and oxygen into a closed loop, which accelerates scale and corrosion. No heat boiler troubleshooting frequently ends at a small leak nobody prioritized.

Pilot Or Ignition Lockouts And Error Codes

Modern controls store fault history, and that history usually names the culprit: flame sensing, a blocked condensate trap, an air pressure switch, or a low water cutoff doing its job. We read the codes before touching anything.
