Precision Temperature in Lakeside has operated from Woodside Avenue since 1987, holding CSLB license #901308 with C-20 and C-43 classifications covering both warm-air HVAC and sheet metal fabrication. That dual classification enables in-house ductwork design and installation, a capability that pairs with the panel-upgrade and circuit-addition work done by Reddy Electric on Alpine Heights Road when new condenser units exceed existing breaker capacity. Commercial refrigeration for restaurants and retail coolers along the Winter Gardens Blvd corridor and Maine Avenue adds an industrial dimension beyond standard residential heating and cooling. Split-system change-outs pull Title 24 permits through San Diego County, and the attic-access requirements on Lakeside's older ranch-style homes often involve coordinated roof-penetration sealing with Weathermaster Roofing Services, Inc. to maintain leak-free curb mounts after equipment swaps. The C-43 refrigeration license authorizes installation and repair of walk-in coolers, reach-in freezer cases, and commercial ice machines rated from fractional-horsepower compressors up to multi-ton condensing units.
