Fall Furnace & Heat Pump Tune-Up Checklist for Fort Smith & Eastern Oklahoma (2025 Guide)

Cold snaps hit the River Valley fast. A quick fall tune-up keeps your system safe, efficient, and ready for those first 40° mornings. Below is a homeowner checklist backed by national guidance—and what we do on a professional tune-up—so you know exactly what matters before winter. If you’d rather not crawl around the attic, book a tune-up with our local team. We service Fort Smith, Spiro, Poteau, Pocola, and everywhere in between.

Quick Homeowner Checklist (Do these now)

  1. Replace or clean your filter
    Check monthly; replace at least every 90 days (more often with pets/allergies). If your system and filter slot allow it, upgrade toward MERV-13 for better capture of fine particles. Don’t force high-MERV filters into undersized/low-static systems—ask us if you’re unsure. ENERGY STAR+2US EPA+2

  2. Set your thermostat for fall
    Verify heating mode works and schedules are set for when you’re home vs. away. Smart thermostats help trim bills without sacrificing comfort. [Link: Smart Thermostat Installation]. ENERGY STAR

  3. Clear supply/return vents
    Move furniture, rugs, and dust build-up so airflow isn’t choked. Poor airflow stresses blowers and can trip safeties. ENERGY STAR

  4. Outdoor unit check (heat pumps)
    Remove leaves/debris around the condenser, keep 18–24 inches of clearance, and ensure the unit sits level. The Department of Energy's Energy.gov

  5. Safety basics
    Test CO detectors, replace batteries, and make sure gas shut-offs are accessible. (We perform combustion and heat-exchanger checks on professional visits.) Goodman

What We Do on a Professional Fall Tune-Up

When you book a maintenance visit, our techs complete an evidence-based checklist that mirrors national guidance:

  • Measure and verify airflow, blower operation, and temperature rise. The Department of Energy's Energy.gov

  • Inspect electrical connections; tighten/measure voltage/current; lubricate moving parts where applicable. ENERGY STAR

  • Check heat exchanger & burners (gas furnaces) for cracks, corrosion, proper ignition, and flame quality; inspect flue/venting. Goodman

  • Check refrigerant system on heat pumps: leak check, proper charge by measurement, defrost cycle operation. The Department of Energy's Energy.gov

  • Ductwork lookover for visible leaks/restrictions and advise on sealing/repairs if needed. The Department of Energy's Energy.gov

  • Filter & IAQ options: confirm correct filter size/fit; discuss MERV upgrades, UV or purification options if the system can handle it. [Link: Indoor Air Quality Solutions]. US EPA

How Often Should I Schedule Maintenance?

At least annually, and twice per year is ideal—once in spring (cooling) and once in fall (heating). That lines up with ENERGY STAR/DOE guidance and leading manufacturers. If you skipped spring, fall is the most important time to catch up. ENERGY STAR+2The Department of Energy's Energy.gov+2

Signs You Shouldn’t Wait

  • Burning smells after a few minutes of runtime

  • Short cycling, strange noises, or weak airflow

  • Higher-than-normal utility bills
    If you notice any of these, book service right away. [Link: AC Repair or Furnace Repair depending on page structure]. CLARK HVAC
