Combined Heating & Air conditioning system maintenance contract.
Why Does My HVAC System Need Maintenance? HVAC systems break down. Even good ones. Maintenance can prevent that. There are three obvious reasons:
Extend the life of your system: - The life expectancy of an HVAC system that has professional maintenance twice a year? 20-25 years.
- The life expectancy of an HVAC system where you change your filter as needed but otherwise ignore it except for full breakdowns or other major issues? 15-20 years, with reduced efficiency for much of its life.
- The life expectancy of an HVAC system that is neglected entirely after install? 5-10 years.
