Arrived to customer’s house. Customer explained that furnace operation is intermittent. He said that he can get it to run if he cycles power to it by flipping the breaker. The furnace was running while we were on site. Gave customer pricing for diagnostic and replacement options. Customer signed off on the S8X2 80 up flow two stage 47k 3.0 option with cut in filter grill above furnace cabinet. Informed customer of weight times on product. Collected half down and measurements of furnace. Will need to come back to complete job. 2-15-22 arrived onsite and completed install as proposed. Provided and install a new thermostat and new S8x2 two stage unit with propane conversion kit set to manufactures standards. Once installed checked for gas and CO leaks and found none to be present. Temperature split is functioning at 30 degrees and is working great! Showed customer how to replace filter and warranty information. Left manuals onsite to set up wireless/Wi-Fi thermostat. Thanks for c
