I arrived to bid a 3 ton system in a 4500 sq ft building and two mini splits in the dressing rooms. I inspected the building with the building manager and he showed me where and what he wanted. I explained that the 3 ton system will not cool the building as needed. He understood and only wants the bathrooms and the dressing rooms conditioned. We will be installing a 3 ton system in the attic space and will be dropping a 10” duct to the bathrooms and kitchen area. The rest of the air will be dumped into the large 4500 sq ft area with a manual damper that they can shut off and just condition those rooms. I will be showing the installation team what will be done due to the custom demands of the building manager.
