Diagnostic completed. Second opinion requested by client. Found 2014 condenser running with low R-22 refrigerant. Air handler is significantly older, likely source of leak. Discussed repair options, leak seal and leak search, but client wishes to pursue longer term solution. Provided estimates for both Carrier GH5 Buildergrade as well as Coastal models, discussed benefits of coastal equipment. Called to confirm available discounts to system, admin confirmed 10% senior discount. Client accepted replacement with GH5 system. Financing completed through GreenSky. Install scheduled for earliest availability.
