Local considerations
Severe winters with lake-effect cold and very high furnace run hours. The result for Janesville 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.
Carbon monoxide risk applies to any combustion appliance in a Janesville home. A working alarm near sleeping areas is the only reliable warning, and a sounding alarm means leaving the building before calling anyone.

Problems we route in Janesville
Keep anyone vulnerable in the warmest room while you wait, and avoid improvising with cooking appliances. A gas range used for heat is a carbon monoxide risk, not a stopgap.

Janesville HVAC questions
What if my furnace is still under warranty?
Parts warranties of five to ten years are common, labor warranties are not. Have the model and serial number ready when you call so the provider can check coverage before fitting anything.
My furnace locks out after three tries. What is that?
Three failed ignition attempts followed by a lockout usually means the flame sensor is dirty, the igniter is weak or gas pressure is wrong. After a long idle summer, cleaning resolves it more often than replacing parts does.
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.
