Here we have two new 16 SEER Single speed Carrier air conditioning and heating systems which were replaced with one Daikin DX20VC 5 ton variable speed system and a 19 Series Mini Split. The mini split was dedicated to the garage and the larger DX20VC took over for the two carrier systems. In the process of merging these systems we zoned the airflow to three areas of the house allowing the multi speed system to control each area independently. This was done with UT3000 Smart Zoning Board.
The benefit to converting these systems is multi fold. Efficiency, Control, Humidity are all the primary improvements from one system to the next.
