A Southern California HVAC contractor focused on doing the work right the first time, and being there when something needs attention later.
We started ADA Mechanical because too many HVAC contractors treat service like a transaction. The fix wasn't complicated: be responsive, be technically rigorous, and be easy to work with on jobs of any size.
Today we serve homeowners, commercial property owners, facility managers, and general contractors across Southern California. A new system for a family in Calabasas, a rooftop unit replacement on Beverly Hills retail, a tenant build-out in Glendale — same crew, same standards, every time.
Whether you're a homeowner whose AC just gave out on a hot Saturday or a property manager planning a multi-building replacement, the work gets the same attention. We've built our reputation on doing both well — and we don't think of one as more important than the other.
Permits, load calculations, manufacturer-spec installation, proper commissioning. The boring details are exactly what decides whether your system runs for 8 years or 18.
You shouldn't need an engineering background to understand a proposal. We explain the options and trade-offs so you can decide with confidence.
HVAC problems don't wait. We answer the phone, dispatch fast, and keep you posted whether you're a homeowner without AC or a property manager with a tenant on the other line.
From single-family homes to multi-property portfolios, we handle the full range of HVAC equipment and project scopes.
Rooftop package units, split systems, VRF/VRV, ductwork design and modifications, tenant build-outs, equipment replacements, and preventive maintenance contracts.
Central air, heat pumps, mini-splits, furnace replacements, air handler installs, and seasonal tune-ups for single-family and multi-family properties.
System down? Tenant calling? We dispatch technicians around the clock across our service area for true emergency situations.
Modernize aging equipment with high-efficiency replacements, smart thermostats, zoning systems, and code-compliant upgrades.
