Plan around summer heat and the HVAC installer
Menifee has recorded 117°F, and summer attic temperatures make long abatement shifts unsafe, so attic and duct removal is best booked early in the morning or outside peak heat where the schedule allows. If the old system has already failed in July, portable cooling for the occupied rooms is worth arranging while the work area is sealed off.
The order of work matters: survey first, then abatement, then a clearance check, and only then the HVAC crew. If 100 square feet or more of asbestos is involved, the district notification adds at least 10 working days, so it pays to test the ducts when you first start collecting AC quotes rather than after the installer has opened the system.
In a Sun City ranch house the ducts usually sit in the attic directly above sprayed ceiling texture, so one survey visit can sample both; the ceiling side is explained under asbestos popcorn ceiling removal. Flooring, manufactured homes and demolition are summarized on the Menifee Asbestos Removal homepage.
