Signs Your Gas Furnace Needs Attention
A gas furnace usually tells you something before it quits so here's a few things worth watching:
- The burner flame is yellow or flickering
- Your CO detector went off
- Soot or scorch marks near the burner
- Banging or rumbling noises when starting
- The unit runs but doesn’t heat any rooms
- Higher bills with no change in use
- Rooms that stay cold no matter what
Because of the nature of gas furnaces some signs are an emergency rather than a simple fix. If you notice a gas smell leave the home immediately and call Spire's emergency line or 911 from outside.
Gas Furnace Repair in Chesterfield, MO
Most no heat Chesterfield, MO calls come down to a handful of parts like igniters and flame sensors as well as pressure switches and blower motors. We run a full diagnostic test rather than swapping components then give you the repair price written in ordinary language before any furnace repair work begins. Our phones are answered 24/7 and Easy Maintenance Club members get priority emergency response.
Furnace Replacement in Chesterfield, MO
When a gas furnace is over 15-20 years old the price of repairs starts to go up because discontinued parts get harder and more costly to source while multiple repairs a year ends up being more expensive than a full replacement. This causes you to spend real money on a short remaining lifespan. Likewise a cracked heat exchanger isn't an upsell because that unit has to come out ASAP for safety reasons. We'll do real load calculations to size the new furnace and cover the venting and gas line requirements before you approve anything. See our gas furnace replacement page for the full rundown.
Gas Furnaces And Combustion Safety
Your gas furnace burns fuel a few feet from the air moving through your ductwork and the heat exchanger is the only thing keeping those separated. A crack in it makes no noise and gives off no smell while the furnace keeps running like normal. That's why the CO test and draft check matter more than anything else we do on the unit. We also look at the flue when the furnace and water heater share a chimney because that setup causes problems on both appliances and it's frequently missed.
Routine Gas Furnace Maintenance in Chesterfield, MO
