What you are likely to have
Older and custom Santa Fe houses often have a gas or propane boiler feeding radiant tubing, baseboards, or a mix of zones. Some systems use a tankless or combi unit for both heat and domestic hot water. A “no heat” call can be the boiler itself, a zone valve, a circulator pump, a thermostat, or air in the lines — not always a failed boiler.
When heat fails
- If one room is cold and others are fine, say so. That often points to a single zone, not the whole boiler.
- Look at the boiler’s display or lights if you can do so safely, and write down any error code before you reset it.
- Propane customers should confirm the tank is not empty before a night-time emergency call.
- Do not keep resetting a boiler that locks out. Repeated hard starts can make a small problem worse.
Maintenance worth doing before winter
An annual service — pressure, combustion, relief valve, pumps, and a check of the expansion tank — is cheaper than a January failure. If you also have mini-splits or a fireplace insert, mention every heat source when you request quotes so the technician is not guessing.
Ask whether the company regularly works on boilers and radiant systems, not only forced-air furnaces, and verify their NM CID license.
