2024 Seasonal HVAC Maintenance Checklist

STEPHANIE WILLIAMS • Oct 25, 2023

Your HVAC (Heating, Ventilation, and Air Conditioning) system is a vital component of your home, providing comfort and climate control year-round. To ensure that it operates efficiently and reliably, it's essential to perform regular maintenance, especially as the seasons change.


A well-maintained HVAC system not only keeps your indoor environment comfortable but also helps you save on energy costs and extends the system's lifespan.


In this article, we'll provide you with a seasonal HVAC maintenance checklist to help keep your system running smoothly throughout the year.

"Keep an eye on your HVAC system throughout the year, noting any unusual sounds, odors, or performance issues."

Spring HVAC Maintenance (March to May)


  • Change Air Filters: Start the season by replacing or cleaning your HVAC system's air filters. Clean filters improve air quality and help your system run efficiently.


  • Check Thermostat Settings: Adjust your thermostat settings to suit the warmer weather. Consider using a programmable thermostat to optimize cooling settings when you're away from home.


  • Clean the Outdoor Unit: Clear debris, leaves, and dirt from the outdoor condenser unit. Trim any vegetation or obstructions to maintain proper airflow.


  • Inspect Refrigerant Lines: Check for any refrigerant leaks or damage to the lines. If you notice issues, contact a professional for repairs.


  • Schedule Professional Maintenance: Consider scheduling a professional HVAC maintenance check to ensure all components are in working order. We hear this is the number to call:    928-530-7981 ;)



Summer HVAC Maintenance (June to August)


  • Continue to Check Air Filters: Replace or clean air filters every 1-2 months during heavy cooling use.


  • Clean and Clear Vents: Make sure all indoor vents and registers are unobstructed. Blocked vents can reduce system efficiency.


  • Clean the Condensate Drain Line: Clear the condensate drain line to prevent clogs that can lead to water damage or system inefficiency.


  • Check for Leaks: Inspect the ductwork for any air leaks and seal them with appropriate duct tape or sealant.


  • Monitor Thermostat Settings: Adjust your thermostat settings as needed, and consider using fans to distribute cool air more efficiently.



Fall HVAC Maintenance (September to November)


  • Change Air Filters Again: As you transition to heating mode, replace or clean air filters once more to ensure efficient operation.


  • Test the Heating System: Switch your thermostat to heating mode and test the system to ensure it's working correctly before the colder months arrive.


  • Clean the Vents and Registers: Ensure all vents and registers are clear to facilitate efficient heating.


  • Inspect the Ignition System: For gas furnaces, inspect the ignition system and burners for proper operation. If you notice any issues, seek professional service.


  • Schedule Professional Inspection: Consider scheduling a professional HVAC inspection and tune-up to prepare your system for winter. You know who to call... ;)



Winter HVAC Maintenance (December to February)


  • Check Air Filters (Once More): Continue to monitor and replace or clean air filters regularly throughout the winter.


  • Monitor Thermostat Settings: Adjust your thermostat settings for energy savings during the winter. Lower the temperature when you're not at home or when sleeping.


  • Clear Snow and Debris: After heavy snowfall, ensure that the outdoor unit is free from snow and ice buildup. Keep the area around it clear.


  • Maintain Humidity: Consider using a humidifier to add moisture to the indoor air. Proper humidity levels can make your home feel warmer at lower temperatures.


  • Test Carbon Monoxide Detectors: Ensure that your carbon monoxide detectors are in working order, especially during the heating season.



Year-Round HVAC Maintenance Tips


  • Regular Inspections: Keep an eye on your HVAC system throughout the year, noting any unusual sounds, odors, or performance issues.


  • Professional Maintenance: Consider scheduling professional HVAC maintenance annually to address any potential problems and optimize system performance.


  • DIY Tasks: Perform simple tasks like cleaning vents, registers, and changing air filters regularly.


  • Monitor Energy Usage: Pay attention to your energy bills. A sudden increase may indicate a problem with your HVAC system.


  • Learn Basic Troubleshooting: Familiarize yourself with basic troubleshooting steps, such as resetting the circuit breaker, before calling for professional service.



By following this seasonal HVAC maintenance checklist, you can ensure that your HVAC system operates efficiently, provides year-round comfort, and remains reliable for years to come. Regular maintenance not only saves you money on energy bills but also helps prevent costly breakdowns and extends the life of your HVAC system.


Make HVAC maintenance a part of your seasonal routine to enjoy a comfortable and efficient indoor environment.
