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 heating maintenance, bring floor-by-floor performance into the scope discussion. If the heater already fails to run, request a diagnostic repair visit. Keep routine maintenance, corrective repair and optional improvements separate on the proposal so you can authorize each knowingly.
