Heating System Burner Adjustment & Efficiency Testing

Bach MeterCombustion testing is no longer an option, it’s a necessity. New technology has been incorporated into oil & gas burners such that the burner can no longer be adjusted by eye. Yet, even to this day, many fuel companies or plumbers will not use electronic analyzers when adjusting your oil burner. That’s means they are relying on guesswork.

With Combined Energy Services, every technician is equipped with an electronic analyzer, thereby ensuring your burner is adjusted with the latest technology. That means you will burn fuel more efficiently. Your CES technician can provide you with a computer printout of the test results.
