This HVAC system replacement on MacPherson Drive in Greenwich, CT followed a failed compressor on an aging Carrier Infinity system. Given the age of the equipment, repairing the outdoor unit alone was not the smarter long-term path, so the homeowner chose a full system replacement.

Carrier Infinity Air Handler, Outdoor Unit, and Controller Replacement

Greenwich HVAC installed a new Carrier Infinity air handler, outdoor unit, and Infinity controller so the home stayed on a matched communicating system. Indoors, we adapted the new air handler to the existing ductwork with a custom sheet-metal transition, set it in a secondary drain pan, and tied in condensate piping with a condensate pump.

Outdoors, we installed the new condenser on a new equipment pad and leveled it, then completed the line set and electrical disconnect work. The old controller was no longer compatible with the new equipment, so we installed a new Infinity controller and ran a full software update until everything was communicating properly.

After startup and testing, both air conditioning and hydro heat were back up and running.
