We solve complex HVAC challenges with the mindset of engineers. As a 4th‑generation family business with 80+ years in engineering, our team designs and installs systems that protect learning environments, preserve budgets, and simplify operations. We focus on indoor air quality, energy efficiency, and lifecycle value—without disrupting instruction or business.
We are trained at manufacturer facilities for Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). Our field teams integrate these technologies alongside AC PRO–sourced equipment and parts to deliver reliable, scalable HVAC solutions across Downey and greater Los Angeles County.
Every campus and commercial property in Downey is unique. We begin with a detailed site assessment, classroom or zone‑by‑zone load calculations, and an analysis of ventilation requirements. We plan around bell schedules, testing windows, events, and business hours—sequencing work for minimal disruption. Our proposals are transparent, with clear scope, options, and total cost of ownership.
For schools, we prioritize low sound levels, fresh‑air ventilation, and filtration that meets district expectations. For commercial clients, we add capacity planning for peak hours, humidity control, and controls strategies that reduce energy costs while maintaining comfort.
We source dependable equipment and parts through AC PRO to ensure rapid availability, standardized components, and responsive support across Southern California.
Our mission is healthy indoor air for healthy lives. We design systems with the IAQ features that matter: right‑sized ventilation, MERV‑13+ filtration, CO₂ monitoring, and optional air cleaning technologies. We can retrofit existing systems to improve air exchange rates, seal and balance ducts, and implement control sequences that respond to occupancy in real time.
We engineer and install to California Title 24, district specifications, and applicable mechanical and electrical codes. Our safety protocols protect students, staff, and visitors during construction, and our commissioning process verifies performance before hand‑off—complete with documentation, training, and maintenance plans.
Based in Los Angeles, we serve Downey and the broader region: Los Angeles County and nearby areas including Orange County, Ventura County, and Western Riverside County. That coverage gives your facilities consistent standards, faster parts logistics via AC PRO, and one team accountable for outcomes.
Our engineers are trained at manufacturer facilities for Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). This training informs our design and field practices across VRF, ductless, and high‑efficiency heat pump systems—tailored to the needs of classrooms, administrative offices, labs, cafeterias, gyms, and auditoriums.
Protect your investment with preventative maintenance aligned to the academic year or business cycle. We provide seasonal tune‑ups, filter programs, coil cleaning, controls calibration, and emergency response to keep uptime high and operating costs predictable. When issues arise, our technicians prioritize Downey facilities with fast deployment and clear communication.
