We know San Bernardino homes.
The San Bernardino basin floor records some of the highest temperatures in the region — heat pools here, and July afternoons don’t apologize. Systems in this city run longer and harder than their counterparts ten miles away, and the math shows it: more run hours, more wear, shorter equipment life when maintenance slips.
The housing stock spans everything: post-war cottages, 60s ranches, apartment conversions, and newer infill. Older homes with undersized returns and add-on ducting are common — houses where the “new” system still can’t cool because the airflow was never fixed. The diagnostic that separates equipment problems from duct problems is worth real money here.
San Bernardino is covered daily — the valley grid to the Verdemont heights — and no-cool calls in a basin-floor heat wave get the urgency they deserve.
