Investing in an HVAC preventative maintenance program will help your business maintain occupant comfort, minimize repairs, save energy, and increase the life and efficiency of your equipment. Casto Technical Services understands that each customer is different. Therefore, no preventative maintenance plan is the same. Casto offers scheduled maintenance agreements (annual, bi-annual, quarterly, etc.) as a proactive strategy to eliminate repairs and prolong the life of the equipment. Casto also offers full maintenance agreements that covers repairs (exclusions apply) on the covered pieces of equipment. Whatever the need, Casto can create a maintenance plan to match that need.
