Would a RHEEM HVAC system manufactured in January 2006 be a Hi Efficiency unit. Model # RAND 036JBZ Serial # 7297 MB 206 27068 Anybody? Thanks
What is the input BTUs and the Output BTUs you can figure out the efficiency from these figures.

Yes, find the output and divide it by the input.
For example, 75,000 btu output divided by 80,000 btu input equals 94 % (.9375) efficiency.
Thanks
