Signs Your Furnace Needs Repair
- Furnace blowing cold air — could be a failed igniter, a tripped high-limit switch, or a thermostat set incorrectly
- Furnace won't turn on — check the thermostat batteries and breaker first, then call for a diagnostic if those check out
- Yellow or flickering pilot flame — indicates a gas combustion issue. A healthy flame should be steady and blue
- Strange smells (burning, rotten eggs) — a burning smell when first turning on the heater is normal (dust burn-off), but persistent odors or a gas smell require immediate attention
- Frequent cycling on and off — usually a clogged filter, a faulty thermostat, or an oversized unit
- Unusual noises (banging, squealing, rattling) — loose ductwork, a failing blower motor, or delayed ignition causing a small gas buildup
Winter Heating in Denton, TX
Denton's winters are mild compared to northern states, but cold fronts can drop temperatures into the teens with little warning. During events like Winter Storm Uri, Denton homes without working heat faced dangerously cold indoor temperatures within hours.
Most Denton homes use gas furnaces, which are reliable and efficient for the area's heating needs. However, because furnaces sit idle for 8–9 months of the year, components like igniters and flame sensors can corrode or fail from disuse. A fall tune-up catches these issues before the first freeze.
Heat pumps are increasingly common in newer Denton construction. They handle mild winters efficiently but may struggle during extreme cold events. Homes with heat pumps often benefit from a dual-fuel backup (gas furnace + heat pump) for the handful of sub-freezing days each year.
