Service agreements are contracts between a service provider and a customer that outline the terms of ongoing maintenance and repair services for an HVAC system or other equipment. The purpose of service agreements is to ensure that the equipment is maintained and serviced regularly to prevent breakdowns, improve energy efficiency, and prolong the life of the equipment. The agreement typically includes scheduled maintenance visits, priority service, discounted repair rates, and other benefits. Service agreements help customers save money, increase comfort and safety, and reduce the likelihood of emergency repairs.
