On Feb. 10, 2015, "the US Department of Energy (DOE) issued a proposed rule for furnaces that would provide significant savings for consumers on their home heating bills, and be among the biggest natural-gas saving standards ever completed by the agency. The new standards would reduce gas and propane furnace energy consumption by about 13% relative to basic furnaces sold today."

"Is your air conditioning bill running wild? Get your utility costs under control by adding an air-side economizer. This device draws in outside air as a form of free cooling. While the potential for savings is significant, facility managers can lose all of an economizer’s benefits if they fail to specify the right features and neglect maintenance. Follow these tips to lock in your economizer’s potential."

Question Everything When Replacing Commercial Boilers

"Although the majority of the boilers have been installed properly, there have been many that were not. Those boilers that were not installed correctly would have been very costly to fix had we not seen the issues prior to installing the new ones. Any issues with the heating system become your issues once the new boiler is installed."
