Commercial School HVAC Services in Fullerton, CA

Design‑Build and Engineering for School Campuses

Every campus is unique. We start with a thorough load analysis, ventilation review, and controls strategy tailored to classrooms, labs, libraries, cafeterias, and gymnasiums. Our engineers design VRF, high‑efficiency rooftop units, and dedicated outdoor air systems that balance comfort, acoustics, and energy performance while supporting modern IAQ targets. We plan phasing to minimize disruption during school hours and breaks.

With AC PRO’s regional distribution strength, we secure equipment and parts fast, helping your Fullerton project stay on schedule. Our submittals are clear, our commissioning is meticulous, and our turnover packages help facilities teams operate systems with confidence.

Indoor Air Quality and Ventilation That Supports Learning

Healthy air drives attendance, focus, and outcomes. We implement right‑sized ventilation with economizers and CO2 demand control, configure sequences for quiet operation, and support filtration strategies such as MERV‑13 where appropriate. Our approach delivers steady temperature, humidity, and fresh air in varied occupancy conditions—morning starts, peak periods, and after‑school programs.

• CO2‑based demand‑controlled ventilation for classrooms
• Economizer optimization and acceptance testing compliant with Title 24
• Filtration and ventilation tuning to meet district IAQ goals
• Quiet, low‑vibration installations for better acoustics

Controls, Energy, and Title 24 Compliance

We integrate open, serviceable controls architectures that your team can manage long‑term. Sequences of operation, trend logs, and alarms are built for transparency and performance. Our Title 24 knowledge streamlines compliance and acceptance testing. We document settings that sustain efficiency while protecting comfort during variable occupancy.

For retrofits, we align scope with incentives when available, and we deliver payback‑minded solutions—variable speed, heat recovery, and zoning to reduce wasted energy.

AC PRO Commercial Solutions

As a trusted AC PRO partner, we source commercial‑grade equipment, controls, and accessories with dependable local availability—reducing lead times and downtime. This supply advantage is essential for school schedules and emergency replacements in Fullerton and across Orange County.

Factory‑Trained Engineering Team

That manufacturer‑level insight helps us design, install, and commission VRF and split systems for reliability, serviceability, and lifecycle value on complex, multi‑building campuses.

Construction, Retrofit, and Phased Upgrades

Whether you’re modernizing portables, replacing aging rooftops, or building new STEM labs, we coordinate with facilities, IT, and security to avoid conflicts and delays. We deliver clean, safe worksites and provide clear timelines that align with bell schedules, testing periods, holidays, and summer breaks.
