A home heating, ventilation, and air conditioning (HVAC) system accounts for up to 44% of a typical home energy bill. Your HVAC system is complex, and needs regular maintenance, just like your car. In fact, twice a year maintenance for your HVAC system can help improve efficiency, and help it achieve its potential life span. A properly maintained system is more effective at helping
you manage costs, comfort and may be less likely to break down over time.
