Boiler Repair in Leawood, KS
A boiler that’s gone cold, lost pressure, or sprung a leak leaves an older home without its quiet, even heat — and in a Kansas winter, that’s not something to wait on. 7th Degree Heating and Air repairs hot-water and steam boilers across Leawood and Johnson County, from cast iron workhorses in century-old homes to modern condensing units, diagnosing the real cause rather than guessing.
What Goes Wrong with Boilers
Boiler problems tend to cluster around a few systems: the circulator pump that moves hot water to your radiators, the expansion tank and pressure-relief components that keep system pressure in range, the controls and aquastat that govern firing, air trapped in the loop that blocks circulation, and leaks at fittings or the boiler itself. On gas boilers, we also verify combustion and check carbon monoxide, the same safety standard we hold every gas appliance to. We diagnose by pressure, temperature, and the behavior of the loop — not by swapping parts and hoping.
Common Boiler Repairs
- No heat — a failed circulator, a control or aquastat fault, an ignition problem, or low water pressure locking out the boiler.
- Uneven heat or cold radiators — usually trapped air needing a bleed, or a circulation problem.
- Low or dropping pressure — a leak, a failing expansion tank, or a feed-valve issue.
- Leaks — at fittings, the circulator, or the boiler body; we find the source rather than just topping up water.
- Noises — banging or kettling — often scale or circulation issues, which our hard water can accelerate.
Frequently Asked Questions
- What are the most common boiler problems?
- No-heat calls usually trace to a failed circulator pump, a control or aquastat fault, or a pressure problem locking the boiler out. Cold radiators often just need air bled from the system. Pressure loss points to a leak or a failing expansion tank. Most are repairable — the key is correctly identifying which system is at fault.
- Why is my boiler not heating?
- Common causes include a circulator pump that’s no longer moving water, an ignition or control failure, or system pressure that’s dropped low enough to lock the boiler out as a safety measure. We check pressure, the circulator, and the controls to pinpoint it rather than replacing parts on a guess.
- My boiler is leaking — is that serious?
- It can be. A small leak drops system pressure over time, which eventually causes no-heat lockouts, and a persistent leak can corrode components. We trace the leak to its source — a fitting, the circulator, the relief valve, or the boiler body — and repair it, rather than just adding water to mask a problem that will return.
- Why does my boiler keep losing pressure?
- Dropping pressure almost always means water is escaping or the expansion tank has failed. That could be a visible leak, a weeping relief valve, or a waterlogged expansion tank that can no longer absorb the system’s expansion. We diagnose which and fix the cause, since chronically refilling a boiler just hides a leak.
- When is it time to replace rather than repair a boiler?
- When repairs become frequent, efficiency has dropped, or the boiler body itself is leaking or badly corroded. A sound cast iron boiler can run for decades with repairs, so we don’t push replacement prematurely — but when the body is failing, we’ll be honest that a new boiler is the better investment and show you the options.
