- Boilers & radiators
Boilers and radiators, in buildings and houses.
Hot-water and steam heat in Spokane's older commercial buildings, apartment blocks and houses: what goes wrong, what we check, and when a boiler is worth keeping.
If a boiler smells, leaks or the pressure is off the gauge
Switch it off if it's safe to, and call. If you smell gas, leave the building and call the gas company or 911 from outside first. A relief valve that's discharging is doing its job — don't cap or block it.
Hydronic systems.
A boiler heats water and a circulator pushes it round a loop to radiators, baseboard or air-handler coils, then back. Most of the problems are in the loop, not the boiler.
- One cold zone
- A stuck zone valve or a failed thermostat.
- Lukewarm everywhere
- A weak circulator, or air in the system.
- Gurgling, banging
- Air that keeps returning — often a sign of a leak or a failed air separator.
- Dripping relief valve
- Usually a waterlogged expansion tank or a fill valve set too high.
Low-pressure steam.
The oldest buildings in Spokane still heat with steam. It's simple in principle — boil water, let steam rise to the radiators, let condensate run back — and unforgiving in practice. Venting, piping pitch and water level matter more than the boiler's age.
- Water level, low-water cut-off and pressure controls.
- Main and radiator vents — the usual cause of uneven heat.
- Water hammer, traced to pitch or trapped condensate.
Apartments and older commercial buildings.
One boiler plant serving many tenants means one fault shows up as many complaints. We trace them back to the loop, zone or control that's actually responsible, write down what we found, and price each fix separately.
Most boilers outside private homes in Washington are inspected under the Department of Labor & Industries boiler program. That inspection is separate from our work — we'll help you be ready for it.
Keep it, repair it, or replace it?
A well-made boiler can run for a very long time, and radiators outlast almost everything. Replacing a working hot-water system with forced air means new ductwork through an old house — rarely the obvious win it's sold as.
When a boiler itself is failing, the options are a new boiler on the same radiators, or a new system entirely. We'll lay out both, in writing, with the trade-offs — no numbers promised before we've seen the house.
