​​​​​​​​​​​​​​​​​​​​Boiler Tune-up Rebates

Enhance the performance, safety and efficiency of your hard-working natural gas boiler with a professional boiler tune-up. Individual boilers are eligible for a boiler tune-up rebate every other year*.

Did you know? Maintaining water quality is essential to your system's performance. Test boiler system water (clean and inhibit if needed), to ensure system efficiency, reduce fuel costs, prevent system failures and reduce environmental impact of operating the boiler system. Most boiler manufacturer warranties require that boiler system water be maintained within certain guidelines for pH and hardness levels. Cleaning and treating a system with poor water quality can improve system efficiency by up to 15 to 20 percent.

  • Using water from the boiler system, test for pH levels (cause of corrosion), overall hardness (cause of scale), copper (product of corrosion), iron (product of corrosion), and chloride (cause of corrosion).
  • Inhibitor manufacturers also offer inhibitor test products to ensure the boiler system water is appropriately treated. ​
