Performed 1 system cooling diagnostics on zoned lennox electric hvac system: I found that the unit was frozen upon arrival. House has sustained water damage. I will provide flood protection options to the homeowner. We have previously provided flood protection options. I found that the upstairs damper motor has failed and would not open. I will email estimates to replace both damper motors and to add updated flood protection to the hvac system. I advised the tenant that the system is frozen and to leave the system off at both thermostats to allow the unit to defrost for 24 hours; unit is experiencing issues. We will need to return once the unit has defrosted and replace the damper motors and perform further diagnostics (after the unit has defrosted). I emailed band aid/flood protection option to the homeowner. Further diagnostics is needed once system has been defrosted and zoning has been repaired; additional repair estimates may follow. Homeowner approved 98 diagnostics fee over the
