Claim This BusinessJesca Heating and Air-Conditioning operates from Glassell Park, California, holding an A rating across 11 verified customer reviews. The contractor handles residential and light commercial heating and cooling work throughout the greater Los Angeles metro, including La Mirada and surrounding neighborhoods. Technicians arrive uniformed and equipped to diagnose system faults on the first visit, whether the job involves a decades-old furnace or a newly installed ductless minisplit.
Pricing transparency distinguishes Jesca from larger competitors. Multiple reviewers report quotes well below national franchise bids, with one Glassell Park customer paying roughly one quarter of a major service companys $12,000 estimate for comparable attic remediation and ductwork restoration. The company handles sheet metal fabrication in-house and maintains relationships with supply distributors to keep material costs predictable for homeowners budgeting a system replacement or emergency repair.
Peter Quinto describes calling Jesca repeatedly after a rodent infestation destroyed his attic AC system. Crews removed damaged ducts, replaced torn insulation, cleaned the main condenser with acid wash, and left the equipment looking new at a fraction of the market rate. Harry Eelman credits Jesca with correcting an entire houses temperature imbalance in a single afternoon after another contractor botched the original installation. Both customers note that technicians explained every step before touching the existing infrastructure.
Seven of nine reviewers award 5 stars, praising on-time arrival, diagnostic accuracy, and fair pricing against competitor bids of three to four times higher. Negative feedback centers on scheduling responsiveness rather than work quality, with two reviewers citing missed calls or cancellation windows exceeding five hours.
