Is Your Building’s Comfort System Causing You Discomfort and Costing You $$$?
Long before your building’s comfort system actually breaks down it silently and unavoidably loses efficiency, leading to increased energy bills and decreased comfort. Improper maintenance can also lead to potential health and safety problems, as well as, decreased employee productivity.
There’s an old saying, “if it isn’t broke, don’t fix it.” However there’s another saying that makes much more sense, “An ounce of prevention is worth a pound of cure”.
Building Operation and Maintenance programs specifically designed to enhance operating efficiency of HVAC systems can reduce energy bills by 5% to 20% without significant capital investment.
Most organizations feel the growing pressure to reduce costs and increase profits. Having strategically partnered with hundreds of businesses, the John W. Danforth Company has the experience to help you balance these issues without compromising the quality of the services your facility requires. We see the following benefits as a direct outcome:
• REDUCED EMERGENCIES • EXTENDED EQUIPMENT LIFE • REDUCED ENERGY CONSUMPTION • OPTIMIZED PRODUCTIVITY • IMPROVED SYSTEM RELIABILITY • CONTROL OF MAINTENANCE BUDGET • OBTAIN SINGLE SOURCE RESPONSIBILITY • REDUCED OPERATING PROBLEMS • OPTIMIZED COMFORT CONDITIONS
Do you:
Perform scheduled preventative maintenance? Have a source for fast, reliable 24 hour emergency service? Have specialized, certified, in-house HVAC maintenance personnel? Monitor and record maintenance tasks?
The John W. Danforth Company has made a commitment to work with building owners and managers to develop proactive preventative maintenance programs to help reduce their operating costs and extend the life of their critical equipment. We are uniquely qualified to custom-design a program that addresses the specific needs of your facility and it’s budget. We would welcome the opportunity to discuss your facility’s operation and preventative maintenance requirements.
