Friar's Plumbing Heating and AC Repair in Chula Vista's Eastlake corridor holds CSLB License #1015634 under the C-20 warm-air heating, ventilating, and air-conditioning classification. The firm's dual plumbing and HVAC scope allows technicians to address a failing gas furnace and the water-heater supply line feeding it in one dispatch, a combined-trade workflow that pairs with the panel upgrades handled by Cano Electric on full system changeouts. Founded in 2018 with U.S. Marine Corps roots, the company covers central and split-system AC installations, heat-pump conversions, and ductless mini-split retrofits from its Jackson Street base near Eastlake Parkway. Whole-house re-pipes coordinated alongside furnace replacements reduce the number of permit pulls required under Chula Vista's municipal building code, a consolidation strategy that parallels the sewer-lateral scope at Solid Plumbing & Drains Inc. Technicians deploy Fieldpiece SMAN480 digital manifolds to measure superheat and subcooling on R-410A split systems, verifying charge levels within the 1°F tolerance required by AHRI 210/240 performance standards.
