Built for High‑Rise Performance

At #1 AC Guys, we engineer and maintain commercial high‑rise HVAC systems that deliver reliability, comfort, and clean indoor air—without driving up operating costs. Our fourth‑generation family team brings 80+ years of engineering know‑how to Fontana’s evolving skyline, combining deep field experience with factory training from Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). We design to your building’s real‑world loads, occupancy patterns, and future growth, so your system performs on day one and year ten.

Design‑Build, Retrofits, and Plan‑Spec

Whether you’re constructing a new tower, repositioning a mixed‑use asset, or replacing end‑of‑life equipment, we manage the full lifecycle: concept, engineering, procurement, installation, commissioning, and ongoing service. We coordinate closely with your GC, architect, and MEP to de‑risk schedules and maintain tenant comfort throughout phased work.

Systems We Specialize In

VRF/VRV systems for high‑rise zoning flexibility and rapid tenant build‑outs
Central plants: air‑cooled and water‑cooled chillers, boilers, cooling towers, heat pumps
DOAS and energy recovery ventilation for code‑compliant, healthy outdoor air
Advanced filtration and IAQ: MERV‑13+, HEPA, UV‑C, bipolar ionization (as specified)
VAV/VVT distribution, hydronic piping, pumps with VFDs, and economizers
Building automation (BACnet integration), remote monitoring, and analytics
Stair pressurization, smoke control coordination, and garage CO/NOx ventilation
Server/IDF room cooling and mission‑critical redundancy where required

Engineering That Pays Back

We prioritize lifecycle value with energy modeling, right‑sizing, and heat recovery strategies that lower utility spend. Expect smart sequencing, VFD optimization, demand control ventilation, and controls tuning that match your tower’s occupancy and usage. Our commissioning team verifies performance at every handoff, from TAB reports to BMS trend logs—so you get documented results, not just promises.

Compliance, Safety, and Quality

We engineer to California Title 24 and local code requirements and coordinate permitting, inspections, and closeout documentation. Our team plans for rigging, craning, and safe access in dense urban sites, implements seismic restraints, and aligns with fire‑life‑safety for smoke control and pressurization. Quality control is built into every step—submittals, factory start‑ups, and warranty support—so your turnover is clean and complete.

Planned Maintenance and 24/7 Response

Protect your investment with predictive maintenance tailored for high‑rise operation. Our programs include seasonal start‑ups, water treatment coordination, vibration and refrigerant diagnostics, coil and filter service, controls checks, and performance benchmarking. When uptime matters, our 24/7 emergency team restores operation fast—and helps prevent repeat issues with root‑cause fixes.

Industries and Building Types

We support Class‑A office towers, hospitality and mixed‑use high‑rises, multifamily/condo buildings, medical office, retail podiums, and parking structures. From core‑and‑shell to tenant improvements, we phase work to minimize disruption and maintain business continuity.
