Three ways a Palm Coast furnace quits in January, and what each one costs to leave alone

What a limping furnace costs by March

Start with the money, because that’s what decides whether people call.

A gas furnace with a dirty flame sensor lights, runs for a minute, loses the flame signal and shuts down. Then it tries again. On a 40-degree night it might do that thirty times, burning gas each attempt and never bringing the house up to temperature. By the end of January the Peoples Gas bill is noticeably higher and the house was never warm. The part that caused it costs less than one month of that.

An electric furnace with a failed sequencer runs one strip instead of three. The house heats slowly, so the blower runs all night, and the strip that still works runs continuously. The FPL bill shows a winter spike with nothing to show for it.

A propane furnace out in Daytona North with a regulator problem underfires, runs long cycles, and burns through a tank fill weeks early. Propane isn’t cheap, and the delivery truck doesn’t come on your schedule.

In all three cases the repair is a fraction of a season of ignoring it, and the diagnostic is quoted before we come. So, who calls, and what do we find?

Who calls us for furnace repair

Most of Palm Coast heats with a heat pump. Furnaces live in three specific places here.

• The older sections on Peoples Gas. Palm Harbor, the Woodlands, parts of Flagler Beach and Bunnell, where the gas main runs and 1970s-to-1990s houses have had a gas furnace since they were built or were converted when the second system went in.
• The west-county acreage on propane. Daytona North, Espanola, Cody’s Corner, Favoretta: well water, septic, a tank in the side yard, and a furnace that may have been installed by someone who’s no longer in business.
• All-electric boom-era homes. Lehigh Woods, Quail Hollow, Seminole Woods, where the “furnace” is an electric heat-strip assembly inside the air handler. Homeowners don’t always know they have one until it fails.

Three winters, three repairs

The Woodlands, a 1984 block home with a gas furnace that won’t stay lit. The owner hears it fire, hears the blower start, then hears it all stop. Flame sensor coated with oxidation after nine idle months in 90-percent humidity. Cleaned, tested for microamps, combustion checked, carbon monoxide verified at zero in the supply air. Forty minutes.

Daytona North, a propane furnace that heats weakly and smells faintly at startup. Regulator output low, burner flames lazy and yellow. Gas pressure corrected, burners cleaned, the heat exchanger inspected with a camera because a yellow flame on an old furnace is a reason to look. Exchanger sound; furnace cleared. The smell was dust burning off, but we don’t assume that on propane.

Lehigh Woods, a 2006 all-electric home where the “heat” blows cold. Thermostat calling, blower running, air at room temperature. One sequencer failed and one strip element open. Both replaced from the truck, amp draw verified on all three stages, thermostat checked so the strips only engage when the heat pump needs help. The owner had assumed the heat pump was dead; it was fine.

Call for furnace repair

Our process on a furnace call

1. Safety before diagnosis. Carbon monoxide measured at the furnace and in the living space on every gas and propane call. If it’s elevated, the furnace is shut down before anything else happens.
2. Watch it fail. We run the sequence and observe: ignition, flame proof, blower, limit. Most faults declare themselves within two cycles.
3. Measure. Flame signal, gas pressure, temperature rise across the exchanger, strip amperage, blower amps, static pressure.
4. Inspect the exchanger on anything over about fifteen years or showing a yellow flame, with a camera where the design allows.
5. Quote, then fix. Flat-rate price in writing before parts go in. Common parts, ignitors, sensors, sequencers, strips, capacitors, boards and motors, are on the truck.
6. Verify. Full heating cycle, combustion or amp readings rechecked, and the numbers on the invoice.

What we stand behind

• Price before the work, and the same price at 2 a.m. as at 2 p.m.
• Parts carry the manufacturer’s warranty; the labor carries our workmanship guarantee. [[CONFIRM WITH JERRY: the guarantee period on repairs]]
• If a fix doesn’t hold, we return. Satisfaction guaranteed is the policy, not a slogan.
• On a cracked heat exchanger, we don’t repair, and we don’t leave it running. You’ll get replacement options, a free estimate, financing with low monthly payments, and a space heater’s worth of honesty about the timeline.

The Palm Coast winter, in one paragraph

January’s normal low here is 49. Most winters include a few nights at or below freezing, and the record is 21. That’s not a lot of furnace hours, which is exactly why furnace faults surprise people: the machine sat through hurricane season in wet air, and the first cold snap finds everything that corroded while it waited. A fall check in October or November is how you find those parts before the night that matters.
