3 systems for downstairs labeled 1, 2, and 3. Same on roof. Units 1 and 3 are heat pump systems that were in recent years converted from natural gas systems. Both of the heat pump systems work. Unit 2 has not yet been converted to all electric system. Ryan is wanting an estimate to convert system from gas over to electric. Will email to Service for Comfort Advisor to quote. All pictures for system have been uploaded.
