Commercial Office Building HVAC Services in Calabasas

When your office building in Calabasas needs an HVAC partner who can handle complex loads, strict schedules, and high expectations, #1 AC Guys brings engineering-first thinking to every decision. We model performance, right-size equipment, and sequence controls so your tenants feel consistent comfort while you control operating costs and downtime.

Engineering-first solutions for office comfort and uptime

Every project begins with a detailed site assessment, load calculations, and a clear scope. Whether you manage a Class A tower or a multi-tenant campus, we coordinate with property managers, GCs, and tenants to phase work around business hours and protect productivity.

• Design-build and plan-spec support for new construction and TI
• VRF/VRV heat pump systems and high-efficiency split systems
• Rooftop units (RTUs), DOAS, economizers, and VAV conversions
• Smart controls, zoning, and building automation integrations
• Indoor air quality upgrades: filtration, ventilation, purification
• Precision commissioning, test-and-balance, and documentation

AC PRO supply advantage

To minimize delays, we source equipment and parts through trusted distribution, including AC PRO. Quick access to RTUs, heat pumps, coils, IAQ components, thermostats, and OEM parts helps keep your schedule intact and your building operational.

That means faster turnarounds for replacements, fewer change orders, and dependable support for ongoing maintenance—especially during peak seasons when lead times matter most.

Healthy indoor air and energy stewardship

Healthy air drives productivity. We design ventilation and filtration strategies to meet or exceed code requirements while managing energy use. Solutions can include:

• MERV 13+ filtration and optional HEPA where appropriate
• Demand-controlled ventilation with CO₂ sensing
• Economizer optimization and heat recovery
• Ultraviolet or bipolar ionization options as needed

We target stable temperatures, low noise, and balanced humidity—all crucial for focus and comfort—while supporting compliance objectives like California Title 24 through careful control sequences and verification.

Factory training and craftsmanship

Our team is trained at the factories of Fujitsu (Japan), Mitsubishi Elektrik (Thailand), Midea (China), Gree (China), and Hier (China). This hands-on education informs our approach to selection, installation, commissioning, and service procedures—especially on large or technically demanding office applications.

Systems we service and install

• VRF/VRV heat pump and heat recovery systems
• High-efficiency RTUs, split systems, and heat pumps
• DOAS with energy recovery and advanced economizers
• VAV/VVT zoning, terminal units, and hydronic interfaces
• Building automation and smart thermostats

Project delivery built around your building

We align scope and schedule to your operational needs, then execute with transparency and precision.

• Assessment: site walk, data logging, and load analysis
• Solution design: options with lifecycle cost comparisons
• Proposal: clear pricing, phasing, and timelines
