HVAC installations engineered to last.

The right install, not just a new one

Most HVAC failures aren't equipment problems. They're installation problems. Wrong tonnage, sloppy refrigerant work, undersized returns, skipped commissioning — any of those will quietly kill premium gear. Our installs start with proper engineering: load calculations, equipment selected to match actual building demand, and a scope of work you can verify line by line.

Commercial installation

We install and replace HVAC equipment across the commercial spectrum:

• Rooftop package units — replacements, like-for-like swaps, and curb adapters
• Split systems — sized and specified for retail, office, and light industrial
• VRF/VRV systems — for multi-zone buildings and tenant improvements
• Ductless mini-splits — supplemental cooling, IT rooms, additions, and retrofits
• Ductwork — new runs, modifications, sealing, and air balancing
• Controls & thermostats — smart and programmable, integrated with your BMS where applicable

Residential installation

For homeowners, we install full systems and individual components — every install treated like it's going in our own home:

• Central air & heat pumps — high-efficiency replacements for aging systems
• Furnaces & air handlers — gas, electric, and hybrid configurations
• Mini-splits — single-zone and multi-zone for additions, ADUs, garages, and primary HVAC
• Indoor air quality — whole-home filtration, humidifiers, and UV systems
• Smart thermostats & zoning — Ecobee, Nest, Honeywell, and zone dampers

What's included in every install

Every ADA Mechanical installation includes a proper sequence of work — none of which we shortcut:

1. Load calculation to confirm correct equipment sizing
2. Permits pulled when required by jurisdiction
3. Manufacturer-spec installation using factory-recommended materials
4. Refrigerant evacuation and proper charging to spec, not guesswork
5. Electrical and condensate work that meets current code
6. Commissioning with airflow, static pressure, and superheat/subcool verification
7. Owner walk-through on operation, filter access, and maintenance

Equipment we install

We work with all major manufacturers and can recommend the right fit for your application and budget — Carrier, Trane, Lennox, Daikin, Mitsubishi, Bryant, Goodman, Rheem, and more. We're brand-agnostic. We recommend what's right for the job, not what carries the highest margin.
