Separate the complaint by floor, zone and schedule
For Elk Grove service, identify the thermostat calling for heating or cooling and the rooms that are not responding. A two-floor comfort difference should be described separately from a system that does not run at all.
For a replacement estimate, include any remodel or room-use change since the existing system was installed. Heco can then discuss capacity and distribution together instead of copying the old unit's nominal size.
For commercial split systems, bring floor-by-floor performance into the scope discussion. Ask whether a partial replacement is approved and practical for the existing equipment. Compare it with a complete matched option using serviceability and total scope, not only the cost of the failed component.
