Local considerations
Severe winters with lake-effect cold and very high furnace run hours. The result for Madison homeowners is that a heating system that barely coped last winter may not cope at all this one, once a component has drifted slightly further out of spec.
Zone valve and baseboard issues in older Madison hydronic systems often get misdiagnosed as boiler faults. If some rooms are warm and others are not, the heat source may be working correctly and the distribution is not.

- AC not cooling
What to do while you wait
- Switch the thermostat off so the system stops attempting ignition over and over.
- Confirm the gas supply valve is open and that a service switch has not been knocked off.
- Check the filter. A blocked one makes the furnace overheat and shut itself down.
- Keep interior doors open so the warmth remaining in the house distributes evenly.

Call (855) 321-3194Questions
Madison HVAC questions
Is a cracked heat exchanger repairable?
No. A cracked heat exchanger is a carbon monoxide risk rather than a comfort fault, and the correct response is replacement of the furnace. Any provider suggesting a patch on one is giving you poor advice.
Can I run a space heater meanwhile?
Portable heaters carry their own fire risk and should never be left running unattended or near fabric. Never use a gas range or an outdoor appliance to heat a room, which is a direct carbon monoxide hazard.
Do I need a carbon monoxide alarm?
If any gas appliance runs in the home, yes. Carbon monoxide is colourless and odourless, and a working alarm near sleeping areas is the only reliable warning. If one sounds, leave the building and call 911 from outside.
Do you work on boilers in Madison?
Yes, where a provider covering your ZIP code handles them. Boiler faults run to pressure loss, circulator pumps, expansion tanks and zone valves, which is a different skill set from forced-air work. Say so when you call.
Why does my furnace smell when it first runs?
A brief dusty smell on the first run of the season is normal as dust burns off the heat exchanger. A persistent burning smell, or any electrical smell, is not. Shut it off and call.
