Slayton Mechanical Contractors in Lakeside has delivered commercial and residential HVAC design-build services from Vine Street since 1988, carrying an A+ BBB accreditation maintained for over 25 years. Title 24 mechanical design is handled in-house for tenant-improvement projects, and the resulting energy-compliance packages integrate with fenestration upgrades from Window Solutions on Riverside Drive to hit California's envelope-performance targets. The commercial client roster spans institutional, healthcare, and restaurant sectors across San Diego County, with the company's Procore project history showing 52 tracked jobs averaging $5.8 million in scope. Residential ductless mini-split retrofits for older Lakeside homes near Lindo Lake County Park pair with gas-line relocation handled by Tatum Plumbing Co on Woodside Avenue when furnace replacement requires re-routing the existing supply run. The fleet maintains dedicated service trucks staffed by technicians who hold EPA Section 608 Universal certification for handling R-410A, R-22, and low-GWP refrigerant transitions on systems ranging from 1.5-ton residential splits to 25-ton commercial rooftop packages.
