About the service
I install and retrofit multi-zone HVAC ductwork and thermostat zoning systems for homes and small commercial spaces where one thermostat can no longer keep every room comfortable. Most call-outs start the same way: an upstairs bedroom that never cools down, a sunroom that overheats, or a finished basement the furnace forgets. My first step on any job is a full existing-ductwork assessment — static pressure readings at the air handler, a run-by-run inspection for undersized trunks, crushed flex, disconnected boots, and leaky joints, plus a room-by-room heat-load estimate so the zoning plan is sized to the house rather than guessed at.
From there I lay out zone dampers at the trunk and branch level, sized to the CFM each zone actually needs, and install motorized dampers with spring-return actuators so a stuck damper fails open rather than starving the whole system. Wiring runs from each damper back to a zone control panel, which I mount, label, and bond to a dedicated bypass damper or variable-speed blower profile — whichever the equipment supports — so static pressure stays within the air handler's rated range when only one zone calls for conditioning.
Thermostat placement gets the same attention as the ductwork: I avoid supply registers, direct sun, exterior walls, and kitchen heat sources, and I set up each zone's thermostat with the correct C-wire or power-stealing configuration so it never drops offline. Once everything is wired, I balance airflow zone by zone with a flow hood and manometer, adjusting dampers and register balancing dials until each room hits its target CFM within a few percent, then document the readings so the homeowner has a baseline for future service.
Typical turnaround is two to four working days for a four-zone retrofit on an existing system, longer if trunk resizing or new supply runs are needed. I supply all dampers, control wiring, and the zone panel, and I test heating and cooling calls on every zone before calling the job finished. Clear before/after photos, a wiring diagram, and a short walkthrough of the zone panel controls are included with every project so the system stays serviceable long after I leave.
