Preventative Maintenance Reduces Energy Costs

An ounce of prevention can prevent a pound of cure!  ~ Benjamin Franklin

That quote could not be more true when it comes to your HVAC equipment.  A successful preventative maintenance program will help you maintain occupant comfort, minimize down time, increase the life of your equipment and maintain the value of your assets. Casto Tech offers regular preventative maintenance programs to satisfy warranty compliance and as a proactive strategy to eliminate repairs. We also offer full maintenance programs to help clients budget for the inevitable costs of owning, operating and maintaining their HVAC systems.

Preventative Maintenance

According to the New Buildings Institute, best practices in building maintenance and operations reduce energy use 10 to 20 percent across all climate zones in the United States.

A study by the building efficiency initiative found “poor maintenance practices can increase energy use by 30 to 60 percent”.  The study included HVAC systems setpoints and schedules, economizer operation, ventilation controls and settings, and HVAC system efficiency and fan power (these last two variables were included as surrogates for adequate maintenance and balancing of the HVAC system).  (
