Good to know in Inland Empire

Riverside and San Bernardino have hot summers, often above 100°F, Santa Ana winds and a long wildfire season, so air conditioning and roofing are year-round businesses here.

Clean the outdoor unit of dust and leaves before summer: in the Inland Empire heat a dirty coil makes the system run longer and fail sooner.
