Amendment 1- The purpose of this Amendment is to:

1-Post Site Visit Questions/Answers/Photos and list of attendees 2- Extend Closing date to Thursday, February 19, 2026 at 1:00 PM local time (Mountain Time). The Heber District Office HVAC system has failed and requires replacement of all AC units and furnaces to have the system operational again. The current system consists of:

Three (3) outdoor AC Units Payne Model #PA13NR060-J (Single Phase) Lennox Model #HS29-036-13Y (Three Phase) Lennox Model #HS24-413-1Y (Three Phase) Two (2) Basement Furnace Units Lennox Model #G20RQ3E-75-6 (Single Phase) Lennox Model #C16-41W-1FF (Single Phase) One (1) Attic Fan Coil Lennox Model #CH19-65-2 (Single Phase) The life expectancy of the AC units is approximately 15-20 years old, and these ones are now 33 years old. They also use a refrigerant (R22) that is 2 generations old.

The furnaces are old heat exchangers that constantly fail. The dampers on the furnaces are no longer functional. Due to long lead times and the need for an efficient replacement of this system, we are recommending replacing the two (2) three phase AC units with single phase units. All other units should be replaced with single phase units as well. We also recommend updating the AC units to units that use the new 454B refrigerant.
