Seasonal Shutdown Procedures

Depending on the season, there are specific shutdown procedures to follow:

Summer Shutdown: Before the cold weather sets in, make sure to clean or replace air filters, as this will improve the system’s efficiency when you start it up again.

Winter Shutdown: In preparation for winter, clean the outdoor unit, and make sure it’s free from debris and ice. Ensure that the ducts are well-insulated to prevent heat loss.

Maintenance Before Shutdown

Proper maintenance before shutdown can prevent issues in the future:

  • Filter Replacement: Changing or cleaning the air filter is essential for maintaining good air quality and system efficiency.
  • Cleaning and Inspection: Clean any dust or debris around the unit and inspect the system for visible damage. Address any issues you find before shutting down for the season.

Common Mistakes to Avoid

There are some common mistakes homeowners make when shutting down their HVAC system:

  • Leaving the Fan On: Many people forget to turn off the fan, leading to unnecessary energy consumption.
