Quick note on timing

The ideal time for fall maintenance is early to mid October. If that window slipped by, November is your next best shot. Don’t wait for the first cold snap to reveal a problem.

Your November tune-up checklist

  1. Replace or upgrade your air filter

    Swap 1-inch filters every 30–60 days. High-capacity 4–5 inch media lasts longer and helps airflow.

    Local tip: many Birmingham homes benefit from better filters to keep indoor air cleaner during winter shut-in.

  2. Test carbon monoxide protection

    Press the test button on each CO alarm, replace batteries, and keep one within 10 feet of every sleeping area. If you have a gas furnace, CO monitoring is non-negotiable.

    Safety

  3. Set your thermostat for heating season

    Program simple weekday/weekend schedules, confirm heat mode, and swap thermostat batteries. Consider a smart thermostat if your routine isn’t consistent.

  4. Clear and inspect the outdoor unit (heat pumps)

    • Trim vegetation 2–3 feet around the unit.
    • Rinse leaves and dust with a gentle hose stream.
    • On the first cold morning, watch a full defrost cycle. Unusual noises or steam that doesn’t stop can mean trouble.
    Reliable performance

  5. Check supply and return airflow

    Open all vents, vacuum the grilles, and make sure furniture or rugs aren’t blocking returns. If rooms still run cold, ask about duct balancing or duct sealing to tame temperature swings.

  6. Flush the condensate drain

    Pour a cup of warm water with a little vinegar into the condensate line access to discourage algae. If you spot standing water or smell something musty, call us for a proper cleanout.

  7. Inspect the furnace cabinet

    Look for rust, scorch marks, or a persistent gas smell. A pro should check burners, the heat exchanger, ignition, and venting.

  8. Dial in winter humidity

    Target indoor relative humidity around 40–50%. Whole-home humidifiers help with dry-air issues; a dehumidifier can steady things during damp spells.

  9. Reverse ceiling fans and seal the envelope

    Flip fans to clockwise at low speed to gently push warmth down. Weather-strip drafty doors and attic hatches so you keep that paid-for heat inside.

  10. Schedule professional maintenance

    A NATE-certified technician will check gas pressure, combustion, static pressure, safeties, blower amps, and refrigerant levels on heat pumps, then calibrate the thermostat. You’ll get a heads-up on parts trending toward failure so you can fix them on your schedule.

Central Alabama specifics we see a lot

  • Indoor air quality takes a hit in winter with closed windows. Better filtration and clean ducts help keep things fresh.
  • Duct sealing in older homes around Birmingham and Homewood often fixes hot-and-cold spots and noisy runs.
  • Air filters sized correctly for the return improve airflow and reduce strain on the system.
