Tips for Optimizing Your HVAC System

Maximize Comfort and Save Energy
Proper use and care of your HVAC system can make a big difference in comfort and savings. Here are some easy tips:

  • Change Filters Regularly: Replace or clean filters every 1-3 months for better airflow and efficiency.
  • Seal Air Leaks: Insulate windows and doors to prevent heat loss or gain.
  • Utilize Programmable Thermostats: Set temperatures to automatically adjust based on your schedule.
  • Schedule Annual Inspections: Regular check-ups can catch small issues before they turn into costly repairs.
