Kyle, TX · Hays County
A burning smell the first time the heat comes on
The first heating cycle after a long Central Texas summer burns off dust that settled on the furnace burners or the electric heat strips. That dusty smell should fade within the first hour. A smell that persists, smells electrical or comes with a carbon monoxide alarm is a different call.
The line is answered 24/7. Visits depend on which contractors are working your ZIP code.
Which smell is it
Dusty or slightly scorched, fading within an hour. Dust burning off the burners or heat strips. Usually normal after months of idle time in an attic.
Hot plastic, rubber or electrical. Turn the system off at the thermostat. It can come from a failing blower motor, a heat strip element or its wiring, or a wire touching something hot.
Rotten eggs. That is the odorant added to natural gas. Leave the house and call 911 or the gas utility from outside before calling anyone else.
Any smell with a carbon monoxide alarm. Get everyone out first, then call for help from outside.
Why heat strips smell in Kyle
About 51% of Kyle households heat with electricity (Census ACS 2020–2024), which usually means heat strips in the attic air handler, alone or behind a heat pump. Strips sit unused for most of the year, so they collect more dust than a furnace that runs often, and they are the most common source of the first-cold-night smell here.
What a technician checks
The blower motor and its capacitor, the heat strip elements, their limits and wiring, and on a gas furnace the burners, the flue and combustion readings. Ask for the readings in writing.
What to have ready when you call
- What the smell is like and how long it has lasted
- Gas furnace or electric heat
- Whether the system still heats
- Your address, ZIP code and attic access
Common questions
Should I change the filter? Yes, if it is overdue; a choked filter makes strips and burners run hotter. It will not fix an electrical smell.
