Local considerations
Long cold winters and a large stock of oil and boiler systems make pressure and circulator faults frequent. The result for Norwalk 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.
Long cold winters and a large stock of oil and boiler systems make pressure and circulator faults frequent. In Norwalk that determines whether heating calls here are combustion problems or refrigerant-cycle problems, and those need different parts on the truck.

- Read next
- AC not cooling
What to do while you wait
- Set the thermostat to off rather than leaving it calling for heat against a locked-out system.
- If you smell gas, leave the building first and call the gas utility or 911 from outside.
- Replace a loaded filter. Restricted airflow trips high-limit switches on furnaces.
- Close off unused rooms and keep anyone vulnerable in the warmest part of the house.

Call (855) 321-3194Questions
Norwalk HVAC questions
What should I do before the provider arrives?
Set the thermostat to off rather than leaving it calling for heat against a locked-out system, replace a loaded filter, and close off unused rooms. Keep anyone vulnerable in the warmest part of the house.
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.
