Why Businesses in Calabasas Choose #1 AC Guys

4th‑generation, family‑owned expertise: 80+ years of cumulative engineering experience focused on real‑world results, not guesswork.
Factory‑trained engineers: Education with leading manufacturers including Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China).
Large & complex projects: We thrive on challenging retrofits, tight timelines, and multi‑zone commercial buildings.
Code‑aligned by design: California Title 24, ASHRAE 62.1/90.1, Cal/OSHA, and local Los Angeles County requirements are baked into our designs.
Commissioned and balanced: Every system is tested, adjusted, and balanced (TAB) and commissioned for documented performance.

Systems We Design and Install

DOAS (Dedicated Outdoor Air Systems): Condition and precisely control outside air separate from heating/cooling for stable IAQ and easier compliance.
ERV/HRV (Energy/Heat Recovery Ventilators): Recover energy from exhaust to pre‑condition incoming air—cutting loads and improving comfort.
Make‑Up Air Units: Maintain building pressure and ensure safe, consistent airflow in kitchens, warehouses, and manufacturing.
VAV and Constant Volume Ventilation: Right‑size airflow by zone with smart controls and demand‑controlled ventilation (CO₂ sensors).
Kitchen & Grease Exhaust: Commercial hoods, ducts, and fans integrated with make‑up air for safe capture and code compliance.
Specialty & Process Exhaust: Labs, salons, print shops, and light industrial spaces requiring targeted capture and filtration.
Parking Garage Ventilation: CO/NOx sensor‑driven systems to clear contaminants while minimizing runtime.
Filtration & Air Cleaning: MERV‑13+ filters, HEPA modules, UV‑C, and advanced IAQ options designed around your risk profile and maintenance capacity.

Health, Comfort, and Energy—Engineered Together

We size and tune ventilation using ASHRAE 62.1 and local code, then elevate performance with demand‑controlled ventilation (CO₂‑based), energy recovery (ERV/HRV), and economizers where appropriate. The result: cleaner air for occupants, protection for sensitive equipment and finishes, and lower utility costs. We can also align with sustainability goals by supporting Title 24 compliance, benchmarking, and utility incentive documentation.

Our Design‑Build Process

1. Discovery & Site Survey: We review building use, occupancy, existing HVAC, roof/structural constraints, and utility rates.
2. Engineering & Modeling: Airflow calculations, duct layouts, control sequences, and energy recovery strategies—coordinated in BIM where needed.
3. Permits & Submittals: Permit‑ready plans, spec submittals, and code narratives tailored to Calabasas and Los Angeles County authorities.
4. Installation: Clean, safety‑first execution with seismic bracing, fire/smoke dampers, and proper clearances.
5. TAB & Commissioning: Airflow verification, controls tuning, and owner training; you receive a commissioning report.
6. Maintenance & Support: Proactive service plans to protect warranties, IAQ, and energy performance.
