MORU-Mount Rushmore National MonumentSupply and Install AC Units

The purpose of this modification is to incorporate the following questions and answers. The proposal due date remains unchanged at 14:00 MDT on July 30, 2012. Question #1: What are the distances from the furnaces to where the A/C units will sit? Answer #1: 10 to 15 feet from unit to furnace. Question #2: Does the Lennox Pulse 21 up draft furnace that you have installed have a variable speed blower or a single stage single speed blower? It is my understanding that the Pulse 21 was only made with a single speed blower. If the Lennox Pulse 21 furnace does not have a variable speed blower you can not get a SEER rating above 15 SEER even with a SEER rating on the air conditioning equipment label that is higher than 17 SEER. Or are you just looking for the air conditioning unit that has label at or above the 17 SEER and changing the furnaces at a latter date to achieve the 17 SEER? Answer # 2: Single speed and you are correct, 15 SEER rating is fine. Currently two units have Central Air installed, 17 SEER Rating is just a starting point if it's not achievable then 15 SEER will work.
