End-of-Summer Air Conditioning Checklist: What Every Minnesota Homeowner Should Know

As summer draws to a close in Minnesota, it's time to start thinking about transitioning your home’s cooling system to make way for the colder months ahead. Properly preparing your air conditioner for storage not only ensures its longevity but also guarantees it will be ready to keep you cool when the heat returns next year. Here’s a comprehensive end-of-summer air conditioning checklist from Air Comfort Heating & Air Conditioning to help you get your AC system ready for storage.

1. Turn Off the Power to Your AC Unit
One of the first steps in preparing your air conditioner for storage is to turn off the power supply. This helps prevent any accidental start-up during the off-season, which can cause unnecessary wear and tear on the system. Locate the electrical circuit that powers your AC unit, and switch it off at the breaker panel.

2. Clean or Replace the Air Filter
Before storing your AC for the season, make sure to clean or replace the air filter. A clean filter improves air quality and ensures that your system is running efficiently. By starting with a clean filter now, you'll have one less task to worry about when it's time to use the AC again next summer.

3. Inspect and Clean the Outdoor Unit
Over the summer, debris such as leaves, dirt, and grass clippings can accumulate around your outdoor unit. This debris can block airflow and reduce your system’s efficiency. Carefully remove any debris from the unit and use a garden hose to gently clean the fins and coils. Be sure to let the unit dry completely before covering it.

4. Check for Any Visible Issues
While cleaning the outdoor unit, take the time to inspect the system for any visible signs of wear and tear, such as cracks, leaks, or rust. Addressing these issues now can prevent them from worsening during the winter months. If you notice anything concerning, consider scheduling a professional inspection before storing the unit.

5. Cover the Outdoor Unit
Covering your outdoor AC unit helps protect it from the elements, including snow, ice, and debris. Use a breathable cover specifically designed for air conditioners to prevent moisture buildup, which can cause rust and other damage. Secure the cover tightly to ensure it stays in place throughout the winter.

6. Schedule an End-of-Season Maintenance Check
Before you officially put your air conditioner to rest for the season, it’s a good idea to schedule an end-of-season maintenance check with a professional HVAC technician. They can perform a thorough inspection, clean the system, and address any minor issues that could become bigger problems down the line. Regular maintenance is key to extending the life of your AC system.

7. Consider Upgrading Your Thermostat
If your thermostat is outdated, now might be a good time to upgrade to a programmable or smart thermostat. These devices allow you to better control your home’s temperature, even when you’re not there. A smart thermostat can also help you monitor your energy usage and make your system more efficient when it’s time to turn it back on next year.

8. Prepare Your Home for the Transition to Heating
As you prepare to store your AC, it’s also important to start thinking about your heating system. Make sure your furnace is in good working order and ready to take over the job of keeping your home comfortable. This transition is easier when both systems are well-maintained and operating efficiently.

By following this end-of-summer air conditioning checklist, you can help ensure that your AC unit remains in good condition during the off-season and is ready to go when the warm weather returns. Proper care and maintenance are essential for extending the life of your HVAC system and maintaining optimal performance.
