As September arrives and the summer heat finally begins to fade, it’s tempting to switch off your air conditioner and forget about it until next year. But for homeowners who want a comfortable, efficient home and a longer-lasting HVAC system, fall is the perfect time to “close out” the cooling season.
By taking proactive steps now, you can prevent issues, save money, and ensure your AC is ready to perform when next summer rolls around. Here’s a six-step checklist every homeowner should consider this September.
1. Schedule a Professional AC Tune-Up
Even if your air conditioner seemed to work flawlessly all summer, a professional inspection is invaluable. A licensed HVAC technician will check for wear and tear, clean critical components, and verify that your system ran efficiently during peak season. During an end-of-season tune-up, one of our technicians will:
- Cleans coils and filters
- Checks refrigerant levels
- Inspects electrical connections and moving parts
- Tests thermostat accuracy
This preventive service helps you spot potential issues before they become costly problems and ensures your AC is ready to handle next year’s heat.
2. Clean or Replace Air Filters
Air filters trap dust, pollen, and debris, keeping both your system and your indoor air cleaner. Over the course of summer, filters can become clogged, reducing airflow and straining your system. Replacing or thoroughly cleaning your filters in September:
- Improves indoor air quality
- Reduces energy usage
- Extends the life of your AC
Even if you regularly change filters, taking one final look at the end of the cooling season ensures no lingering debris remains.
3. Inspect Ductwork and Vents
Ducts and vents circulate air throughout your home, but leaks or blockages can decrease efficiency and increase utility bills. Inspect your ductwork and vent openings for:
- Dust accumulation or debris
- Loose connections or damaged sections
- Signs of mold or moisture
Professional duct cleaning or repairs, if needed, can improve airflow and keep your system running efficiently next year.
4. Check Outdoor Components
The outdoor condenser unit is exposed to the elements all season long. Leaves, dirt, and debris can accumulate around the unit, restricting airflow and reducing efficiency. End-of-season maintenance for your outdoor AC unit includes:
- Clearing debris from around the unit
- Checking the fins for damage and straightening if necessary
- Inspecting the condenser coil for dirt or buildup
A clean, unobstructed outdoor unit will start the next cooling season in peak condition.
5. Evaluate System Performance
Take a moment to reflect on how your AC performed over the summer. Did some rooms feel cooler than others? Did the system run longer than usual or make unusual noises? Noting performance trends now helps your technician identify issues during your tune-up, ensuring your AC runs efficiently next year.
6. Prepare for Winter and Beyond
Finally, consider seasonal adjustments to protect your system:
- Turn off the AC completely and cover the outdoor unit if recommended by your technician
- Set the thermostat to a conservative setting for fall heating
- Schedule any necessary upgrades or repairs for the off-season when availability is better and wait times are shorter
This forward-thinking approach helps homeowners avoid surprises and keeps the HVAC system in top shape year-round.
