At the Tim Hildreth Company we believe our maintenance programs should be performed by our well-trained & certified service technicians who can find & address concerns before complex problems that shut down your system. Our Technicians will use our Custom Preventative Maintenance Check-List & address any areas of concern. These Check-Lists are completed while we test your equipment and are also used to help us track any changes in performance from the previous years. Upon the completion of each scheduled maintenance check, the check-lists are returned to the shop where we review the information & keep it on file for future scheduled maintenance.

Preventative maintenance & water quality are key factors in the life of your equipment.  The best way to accomplish this is by taking care of your boiler room equipment before it turns into an emergency. Waiting until your equipment fails to do any repairs will turn into an emergency that will cost you more money or will cause you to be down for an extended period of time. Scheduling a preventative maintenance plan that fits your needs will save you time & money. We at the Tim Hildreth Company like to eliminate any potential problems before they become an emergency & can set up a custom preventative maintenance plan that works best for you.

Boiler operators have control over two basic aspects of the chemical program; blow down and chemical feed. Blow down requirements are determined by the type & amount of impurities that exist in the makeup water. Blow down rates directly affect chemical feed rates. A complete analysis of the raw & makeup water is the first step in establishing the correct program. 

​When boiler water pH is not within the proper range, calcium reacts with phosphate to form harmful calcium phosphate scale. By keeping up with your boiler's water pH level, you are saving your boiler from scale build up which will decrease your heat transfer service & efficiencies.
