Seasonal HVAC Maintenance Checklist

HVAC Maintenance Checklist

In Hammond, LA, and neighboring regions, adapting your HVAC equipment for each season is crucial. Our blog post, ‘Seasonal HVAC Maintenance Checklist,’ provides homeowners and business owners with expert advice to maintain optimal performance and comfort of their HVAC systems year-round.

Maintaining your HVAC system is crucial for ensuring comfort and efficiency in your home or business, especially in the varied climate of Hammond, LA, and surrounding areas. A well-maintained heating and cooling system not only keeps your space comfortable but also saves on energy costs and extends the lifespan of your equipment. Here’s a comprehensive seasonal HVAC preventative maintenance checklist to help you stay on top of your HVAC unit needs:


  • Inspect and Replace Air Filters: Check your air filters every month and replace them as needed. Spring pollen can clog filters faster than usual.
  • Clean Outdoor Units: Remove any debris, leaves, or dirt that accumulated around your outdoor units during the winter.
  • Check Refrigerant Levels: Low levels can indicate a leak. Ensure they are adequately maintained for efficient cooling.
  • Inspecting and Cleaning Condenser and Evaporator Coils: In the spring, it’s important to clean the condenser and evaporator coils to prevent overheating and ensure smooth operation.
  • Schedule Professional Inspection: Have a professional service your system to prepare for the summer heat. This includes checking thermostats, electrical components, and controls.
  • Test Air Conditioning: Run your AC for a test cycle to ensure it’s cooling effectively.


  • Monitor Humidity Levels: High humidity can strain your HVAC system. Consider a dehumidifier if necessary.
  • Keep Vents Unblocked: Ensure all vents are open and not obstructed by furniture or curtains.
  • Inspect Insulation: Proper insulation keeps cool air in, reducing the workload on your AC.
  • Regularly Clean Air Filters: Continue to check and replace air filters to ensure efficient airflow.
  • Check Drain Lines: Clear any clogs in the AC drain lines to prevent water leaks and potential damage.


  • Prepare for Heating: Switch from cooling to heating and test your heat pump or heating system before the cold weather sets in.
  • Check and Replace Filters: As you start using your heater, clean or replace the air filters.
  • Inspect Heating Elements and Heat Exchanger: Look for signs of wear or damage.
  • Clear Around Outdoor Units: Remove fallen leaves and debris from around heat pumps or outdoor units.
  • Schedule a Professional Check-Up: Have a technician inspect your furnace and heating system to ensure it’s ready for winter.


  • Regularly Check Filters: Winter often means closed windows and more indoor time, so clean air is crucial.
  • Checking for Duct Leaks: Inspecting ducts for leaks is an important step in maintaining heating efficiency during colder months.
  • Inspect Ventilation: Ensure your home or business is adequately ventilated to prevent air quality issues.
  • Monitor Thermostat: Keep an eye on your thermostat to ensure it’s functioning correctly and efficiently.
  • Check for Drafts: Seal any drafts around windows and doors to keep the heat in.
  • Inspecting Exhaust Outlets: Checking your flue system and chimneys for obstructions is crucial to prevent dangerous gas leaks, carbon monoxide buildup, and gas pressure, especially in winter.
  • Inspecting Cooling Components: As winter ends, it’s important to check the air conditioner to ensure it’s ready for warmer weather.
  • Professional Maintenance: If you haven’t already, get a professional to inspect your heating system, especially for gas furnaces, to ensure safety and efficiency.

Year-Round Tips:

  • Thermostat Settings: Adjust your thermostat settings for energy savings when you are away or asleep.
  • Lubricating Moving Parts: Regular lubrication of moving parts in your HVAC system, especially during the summer-to-fall transition, is crucial for smooth functioning.
  • Inspecting Electrical Connections: Ensuring all electrical connections are secure and safe is a vital year-round maintenance task for your electrical system.
  • Regularly Listen for Unusual Noises: Any strange sounds from your HVAC system could indicate a problem.
  • Keep a Maintenance Log: Track when you perform maintenance tasks and any professional services done.

Regular maintenance of your HVAC system is key to its longevity and efficiency.
