What should I know about my home's HVAC system?

Know the age of your furnace and air conditioner and their maintenance history. Replace filters every one to three months. Change batteries in the thermostat annually. Have a professional service the system twice a year: once before heating season and once before cooling season. Learn what to do if the system stops working and where the emergency shutoff is.

Why It Matters

Your HVAC system is the most expensive system in your home. Proper care extends its lifespan by years and keeps your energy bills under control.
