Our customer Transwestern Commercial contracted with Timberline Mechanical to replace 2 – 100 ton and 1 – 90 ton Mammoth packaged cooling only roof top units along with the equipment controls. Our Service Retrofit team, working with the local Aaron rep to select units to meet the previous capacities. We ended up replacing the units with 2- 110 ton and 1 – 100 ton Aaon RL series RTUs. This was a challenging job since the equipment needed to be replaced outside of office hours. The first weekend, we replaced the 100 ton unit and the second weekend we replaced both of the 110 ton units. In both cases we met the requirement of the customer and had them up and running well before Monday morning.
