Gas Smell Near Furnace
Here's what typically causes this, and why an on-site diagnostic — not a phone guess — is what gets you an accurate estimate.
Loose Fitting or Connection
A minor leak at a joint or connection.
Failing Valve
Gas valve not sealing properly.
Cracked Heat Exchanger (rare)
A more serious safety issue requiring immediate attention.
Why diagnosis matters: A symptom like this can trace back to several different root causes, and the fix — and its cost — depends entirely on which one it is. Roxly doesn't quote a repair price over the phone based on a symptom alone: a technician inspects the equipment on site, tests the likely components, and confirms the actual cause before giving you a firm estimate. That's what makes the quote accurate instead of a guess you find out is wrong after the work starts.
What should I do right now if I smell gas?
Leave the area, do not operate switches or the thermostat, and call your gas utility's emergency line immediately — then call us for the repair once it's safe.
Is this always an emergency?
Any gas smell should be treated as urgent — safety first, diagnosis second.
