Heat exchangers are the components that draw heat from the burned gas. To draw more heat from the air they burn, energy-efficient furnaces supplement the primary exchanger with a second exchanger. Because the exhaust gases in that second exchanger might yield a corrosive acidic condensate, the second exchanger is made of stainless steel, lined with plastic, or otherwise protected.

CM Heating performed a Gas Furnace Diagnostic. Customer wanted his echo bee thermastat installed that he had bought himself. Furnace was working fine just wanted his thermastat installed. He thought that the $99 service fee was going to cover that but explained to him what the service fee was for, and explained that there is a additional install fee for the stat. Customer didn’t want to pay the additional fee so I called the office had them listen to the call to make sure we explained to the customer correctly and to see how they would like me to proceed. So I quoted the customer the fee to install the thermostat but he didn’t want us to install it so I left.
