We offer a wide range of HVAC services catered to both residential and commercial clients. Even the all-powerful Pointing has no control about the blind texts.
From design‑build to retrofit, #1 AC Guys delivers Commercial DDC that unifies HVAC equipment, sensors, and dashboards into a resilient BAS. Our engineers develop sequences of operation, point lists, and graphics; integrate BACnet/Modbus devices and VRF by Fujitsu and Mitsubishi Electric; and commission to California Title 24, ASHRAE, and owner standards. Expect faster diagnostics, healthier indoor air, and real‑time energy insight with trend logs, alarms, and remote access. We support multi‑site portfolios and complex facilities—offices, healthcare, education, hospitality, retail, and industrial—across Los Angeles County, Orange County, Ventura County, and Western Riverside County.
Every successful DDC deployment starts with clear engineering. Our 4th‑generation family of engineers translates your goals into precise sequences of operation, robust network architecture, detailed point lists, and clean graphics. We design for maintainability, redundancy, and life‑cycle value—so your BAS remains stable during growth or tenant changes.
We integrate BACnet/IP, BACnet MS/TP, Modbus RTU/TCP, and migrate legacy systems to modern, open BAS. Our team commissions end‑to‑end: sensor calibration, point‑to‑point checks, alarm verification, trend set‑up, and functional performance testing—all documented against the agreed sequence and owner’s project requirements.
Modernize legacy DDC with phased cutovers scheduled around your operations. We map existing points, build temporary bridges where needed, and maintain environmental conditions while we transition to a safer, more insightful BAS. Your occupants stay comfortable, your critical rooms stay protected, and your team gets better visibility from day one.
Clear programming and dashboards drive faster decisions. We implement user‑friendly graphics, folders, and naming conventions; enable trend logs for key KPIs; and configure alarms to reduce noise while escalating truly urgent events. Expect actionable reports on comfort, energy, and equipment health—accessible from any device.
Your building’s health matters. We engineer for clean indoor air by monitoring CO2, humidity, temperature, and filtration status, and by coordinating outside air and economizers to support ventilation goals. We align work with California Title 24, relevant ASHRAE standards, and owner guidelines—supporting acceptance documentation and staff training.
We stand behind our systems with responsive service plans. From quarterly tune‑ups to 24/7 monitoring options, our team keeps your BAS secure, patched, and optimized. We train your facility staff to operate and adjust sequences safely, and we document everything so knowledge stays with your building.
We are a family business rooted in 80+ years of engineering experience. Our specialists are factory‑trained by Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). That depth shows up in our ability to solve complex control challenges, from multi‑building campuses to mission‑critical spaces, with solutions that are practical, secure, and future‑ready.
Offices and corporate campuses, healthcare and labs, education, hospitality, retail, light industrial and manufacturing, data rooms and technology suites, and mixed‑use and multifamily common areas. Whether you manage one facility or a regional portfolio, we tailor DDC to your operational reality.
We proudly serve Los Angeles County and nearby Orange County, Ventura County, and Western Riverside County—bringing local code knowledge, fast response, and consistent support to Southern California businesses.
