As the last snowbanks melt and tulips stretch toward the sun, many homeowners embrace a good spring cleaning to refresh their space. While you're decluttering closets and dusting corners, it’s also the perfect time to prepare your HVAC system for the warmer months ahead. 

Seasonal HVAC maintenance —especially in spring and fall—is key to extending the life of your system, maintaining efficiency, and avoiding costly breakdowns during peak seasons. With a few simple steps, you will save money, improve comfort, and enjoy peace of mind as the temperatures rise.

Homeowners in New Hampshire appreciate the many benefits of regular spring maintenance, including efficiency and lower energy bills.

HVAC Spring Maintenance: Step-By-Step

1. Test Your AC Early

Don’t wait for the first sweltering day to find out your AC isn’t working. Run your system now while the weather is mild. Set your thermostat to cooling mode, let the unit run, and watch for red flags: strange noises, odd smells, poor airflow, or warm air. If anything seems off, scheduling a spring repair avoids the summer service rush.

2. Change Your Air Filter

This simple step can have a huge impact. Dirty filters restrict airflow, reduce system efficiency, and worsen indoor air quality. Replace filters every 1–3 months, depending on your filter type and household factors like pets or allergies. During pollen season, you may need to change it more frequently.

3. Clean Around the Outdoor Unit

Winter can leave behind debris, leaves, and overgrowth. Gently clear the area around your outdoor condenser, ensuring at least two feet of space on all sides for proper airflow. A technician can clean internal components during your tune-up, but clearing the perimeter sets your system up for success.

4. Check Your Thermostat Settings

These days, most thermostats are either programmable or smart, and spring is a great time to update their settings. Often, changing seasons means new schedules; therefore, your thermostat will need to reflect such adjustments. Typical changes to routines include changes in occupancy, time spent at home, and even periods during the day when you may choose to turn off your system completely and open the windows.

5. Inspect Ductwork and Vents

Blocked or leaking ducts will greatly reduce the efficiency and effectiveness of your system's ability to carry cool air throughout the building. Remove vent covers and vacuum inside to remove dust and debris. Make sure vents are open and unobstructed by furniture or curtains.

6. Schedule a Professional Tune-Up

Certain tasks are best left to certified HVAC technicians. During a professional spring tune-up, a technician will:

  • Tighten electrical connections
  • Check refrigerant levels
  • Clean coils and drains
  • Lubricate moving parts
  • Test system controls
  • Ensure overall system efficiency

Most HVAC companies will offer maintenance agreements that include twice-year tune-ups, which many find reduces scheduling and cost worries.
