The six weeks it matters
Heating gets asked to work about six weeks a year. We make sure it can.
Gulf Coast winters are short and mild enough that a heating system can sit untouched from March to December and nobody notices, until the one week it's actually needed. That's exactly when a neglected system tends to fail.
Why an unused system fails on the first cold snap
A furnace or heat pump that's been off for nine or ten months collects dust in places it never gets cleared, and a pilot or igniter that's sat idle can fail the moment it's asked to fire again. Contactors and relays that would show wear over a normal heating season instead sit dormant, then get asked to work all at once when the first real cold front rolls through Cypress. Heat pumps, which most of the newer systems out here run, have to reverse the same refrigerant cycle that's been cooling the house all summer, and if that reversing valve or the outdoor coil has an issue, a cold snap is the first time anyone finds out. Gas furnaces have their own version of the same problem, mostly around ignition and the pilot assembly. Either way, the fix is checking it before December, not during it.
The burning dust smell on first run, explained
The first time a furnace or heat pump fires up for the season, a faint burning smell for a few minutes is normal, it's dust that settled on the heat exchanger or coil burning off. It should fade quickly and not repeat on the next cycle. A smell that lingers, gets stronger, or smells electrical rather than dusty is not that, and that's worth a call rather than waiting it out.

Test it in autumn, not December
A short check now beats a no-heat call on the coldest morning of the year.
Running the system for ten minutes in October or November while the weather is still forgiving is how a failing igniter or a stuck reversing valve gets found on a weekday afternoon instead of during an actual cold snap. It's the same logic as AC replacement planning, catch the failing part before it decides the timing for you. If a system has already gone quiet mid-season, that's an emergency callout, and the office runs seven days a week for exactly that. See everything else we handle on the services page.
