Short answer: before Alcoa's first hard freeze, replace your air filter, clear the outdoor unit, test your thermostat in heat mode, and schedule a professional heating tune-up. A pro should test ignition and safety controls on a furnace, and refrigerant performance, defrost and backup heat on a heat pump.
Fall is the best time to service your heating system. Technicians can catch worn parts before they fail on the coldest morning of the year, and you avoid the rush of no-heat calls that follows the first cold snap in Blount County.
What can I do myself before winter?
- Replace the air filter. Start the season with a clean one. Most 1-inch filters need changing every 1 to 3 months. See how often to change your air filter.
- Clear the outdoor unit. Remove leaves, pine straw, mulch and anything stored against it. Keep about 2 feet of clearance.
- Test the thermostat. Switch to Heat, raise the temperature a few degrees and confirm warm air within a few minutes. Replace thermostat batteries.
- Open vents and returns. Move furniture and rugs off grilles so air can circulate.
- Test smoke and carbon monoxide detectors. This is essential in any home with gas heat or an attached garage.
- Listen on the first run. A light burning-dust smell that fades is normal. Banging, grinding or a lingering electrical smell is not.

Why fall maintenance matters in Alcoa
East Tennessee weather swings from mild afternoons to near-freezing mornings, and heat pumps work through both heating and cooling seasons. That year-round use adds wear. Many of the no-heat calls we see in winter, such as dirty flame sensors, weak capacitors and failed defrost controls, are the kind of issues a fall tune-up is designed to catch early.
Maintenance also matters for warranties. Many equipment manufacturers expect regular professional maintenance, so keeping records can help protect your coverage.
How do I make tune-ups automatic?
A True Comfort Plan schedules seasonal maintenance for you, so your system gets checked before both heating and cooling season without you having to remember. It is the easiest way to avoid surprise breakdowns.
