Commercial and residential preventative maintenance agreements are critical to optimizing your HVAC system’s energy efficiency. Utility bills will naturally vary from month to month, but a system that is regularly inspected and cared for will be able to take on the seasons in stride.
HVAC systems are virtually guaranteed to lose efficiency over time. Any mechanical system will experience normal wear and tear. The rate of that decline, though, is controllable. Regular checkups will ensure that minor issues can be corrected and adjustments can be made.
The effective life of your system isn’t necessarily defined as the time until your unit shuts down. Rather, it can be thought of as the time your unit can operate efficiently without having to be replaced.
