Background: Northeast Ohio is nearing its upcoming seasonal milestone. Within the next month or so, daytime temperatures will hold steady above 60-degrees - marking the seasonal end of the furnace’s use (largest energy consumer Oct-May).
Prior to the start of summer’s 80-degree temperatures, the home will be naturally ventilated - via screened windows.
Assistance Needed: Seeking assistance in identifying the the furnase’s baseline. I’d like to store this offline (Excel Spreadsheet) and compare it against the upcoming Oct-May 2021 heating-season. This will serve as my first-level indicator of future potential mechanical problems that will definitely arise - in upcoming years ahead!
Your assistance and guidance will be greatly appreciated! Subsequently, I will apply all learnings to each of the other major appliances.
