Call to Schedule →Does Your Affton Furnace Have These Problems?
These heating problems are common across Affton — and most have straightforward causes. A proper diagnostic confirms the issue before any repair begins.
- →Gas pressure below required operating range — weak flames, ignition failures, and safety shutoffs result
- →Incomplete combustion creating excess CO — dirty burners or gas pressure issue; combustion analysis needed
- →Manifold pressure drifting out of spec — gas valve issue causing variable heat output and efficiency loss
- →Burners with uneven or lifted flame pattern — dirty burner ports or gas pressure problem; clean and retest
- →Delayed ignition causing loud startup bang — dirty burners lighting all at once; stresses the heat exchanger
- →Flue gas spillage detected at draft hood — negative pressure in home causing backdraft; serious safety concern
- →Gas valve opening slowly or partially — causes start delays and irregular flames; test and replace if needed
- →Combustion air supply restricted by construction — blockage in intake pipe; common on newer tighter homes

Common Furnace Repair Questions in Affton
Very urgent in cold weather. Without heat, pipes can freeze within hours in extreme cold. Call us immediately — we prioritize no-heat emergency calls.
We answer 24/7 — holidays included. No surcharge, no voicemail. A live dispatcher takes your call and sends a technician the same day.
In mild weather, possibly. In cold weather, waiting risks frozen pipes and health hazards. A small problem now often becomes a larger one under continued strain.
Frequent cycling, rising energy bills, unusual sounds, yellow flames, and repeated limit switch trips are all signs a furnace is approaching a major failure.
Extreme cold puts maximum demand on every component. Marginal parts that held up all fall often fail on the first truly cold night of the season.
A loud bang at startup suggests delayed ignition — a serious issue that stresses the heat exchanger over time. Schedule service promptly.
Sudden failures are often components that were marginal for weeks. Igniters and capacitors frequently fail without gradual symptoms beforehand.
With outdoor temps below 20°F, pipe freezing can begin in 6–8 hours in uninsulated areas. Don't wait — call us for immediate emergency dispatch.
