Switching the cooling off in an empty valley house is not a saving
An owner looking at a power bill on a vacant unit asks for the thermostat to go off, and in July that request costs more than the bill.
A closed-up house in Enterprise or Spring Valley gets far hotter inside than the outdoor reading suggests. Attics run hotter still, and the house sits in that condition for days at a time with nobody opening a door.
The damage is unglamorous and expensive. Vinyl plank lifting at the seams, cabinet and trim glue letting go, caulk and window seals failing, paint blistering, the wax ring under a toilet giving up, anything left in the garage ruined.
A phone brought in to film the walkthrough will throttle and shut itself down before the walkthrough is finished, which tells an owner more about the conditions than any sentence you could write about them.
Cooling equipment runs on the same clock. A condenser working against a Mojave cooling load through a long summer wears out on a schedule an owner from a mild place has not accepted yet, and it fails in the weeks when every technician in the valley is already booked.
