Replace HVAC AAON Package Unit at RMB Regional Fairgrounds Ball Room B
Submitted By: Yolanda Moreno, Public Works
Department: Public Works  

Authorize a Texas Tips Contract No. 170201 with Pro Tech Mechanical, Inc. for purchase and install of a 70 Ton AAON HVAC Package Unit, with a 5-Year Compressor Warranty (no labor or refrigerant included) for Ball Room B at the RMB Regional Fairgrounds. 
The existing 70 Ton AAON unit is a side discharge package unit with 4 compressors, activated in sequenced stages, to save energy and reduce wear and tear.  The sequential use of compressors occurs from 1 through 4 stages as dictated by the cooling load.
Purchase in the amount of $141,571.00 will be made with Pro Tech Mechanical, Inc. who provided the best quote.  The existing unit is 13 years old and beyond its useful life span of between 10 and 12 years for outside units.  Due to wear and tear from the UV (ultra violet) rays, weathering, oxidation, acid rain, sea-salt, dirt, high winds carrying dust inflicting erosion on the outside condensers and normal wear and tear, these outside units deteriorate faster than units housed inside a building.  In the last 2 years we have replaced two of the compressors.  The lead time to replace units of this size is about 5 months because they are specially fabricated, tested and then shipped by the factory.  It is therefore in the County's best interest to replace this unit right now to preempt expensive breakdowns and repairs and downtime in the summer of 2020. (Form 1295 Certificate Number 2019-560707, HB 89 and Debarment Statement)
