As October settles over Fort Mohave, Bullhead City, and the greater Mohave County area, the scorching triple-digit summer temperatures begin their gradual retreat. However, Arizona’s desert climate presents unique challenges that make fall HVAC maintenance not just recommended — it’s essential for year-round comfort and system longevity.
Why Fall HVAC Maintenance Matters in Mohave County
- Extreme heat stress from temperatures regularly exceeding 115°F
- Constant dust infiltration from Arizona’s arid environment and seasonal dust storms
- Severe UV degradation of outdoor components in the intense desert sun
- Daily temperature variations of 30–40°F causing frequent cycling
- Ultra-low humidity affecting system efficiency and indoor air quality
Your October HVAC Maintenance Checklist
- Replace all air filters immediately — don’t wait another week
- Check filters monthly during fall due to ongoing dust exposure
- Consider upgrading to higher-MERV rated filters for better dust capture
- Clear debris from around outdoor units (tumbleweeds, dust)
- Inspect and clean outdoor coils to remove desert dust
Thermostat Optimization for Desert Climate
- Test thermostat accuracy with a separate thermometer
- Program settings for daily temp swings (35–45°F)
- Set wider comfort bands to reduce cycling
- Adjust scheduling for sunrise/sunset changes
Heating System Preparation
- Test furnace startup and listen for unusual noises/smells
- Inspect all visible components for heat damage, corrosion, or wear
- Clear furnace area of stored items/debris
- Check pilot lights and ignition systems
- Ensure proper ventilation clearances
Ductwork and Ventilation Assessment
- Check all vents/registers for dust and obstructions
- Ensure furniture, curtains, or stored items don’t block airflow
- Inspect for visible duct damage from heat or settling
- Consider professional cleaning due to dust exposure
