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.
As high‑rise HVAC engineers, we integrate Lennox rooftop units, VRF, split systems, and DOAS with smart controls to deliver stable comfort from lobby to penthouse. Our design‑build approach addresses vertical shafts, high static pressures, smoke control, ventilation rates, and energy code compliance from day one. We plan crane lifts, rigging, curb adapters, and phasing to minimize tenant disruption, then commission every sequence for peak efficiency and IAQ. Backed by 80+ years of engineering experience and fourth‑generation craftsmanship, #1 AC Guys solves complex high‑rise challenges others avoid—on time, within budget, and with measurable performance results across Los Angeles, Orange, Ventura, and Western Riverside Counties.
High‑rise commercial HVAC demands more than equipment swaps. We engineer complete Lennox‑focused solutions that account for static pressure, long refrigerant and condensate runs, vertical transportation, mechanical room constraints, smoke control interfaces, and mission‑critical uptime. Our team balances ASHRAE 62.1 ventilation, 15 refrigerant safety, and 55 thermal comfort with Title 24 and CALGreen requirements to optimize energy and IAQ without sacrificing reliability.
Whether you operate offices, hospitality, mixed‑use, healthcare suites, or data floors, we design N+1 redundancy and robust controls, apply heat recovery where it pays, and right‑size equipment to reduce lifecycle cost—not just first cost.
We plan and deploy Lennox rooftop packaged units (RTUs), VRF, split systems, and dedicated outdoor air systems with demand control ventilation, economizers, VFDs, and BACnet integration. Our engineers coordinate crane picks, street closures, curb modifications, vibration isolation, and seismic bracing specific to Los Angeles requirements. We also retrofit older Lennox fleets with high‑efficiency models, advanced filtration, and modern control sequences for stable comfort and lower utility bills.
Every project begins with a detailed site assessment, load calculation, and risk review. We deliver clear scopes, schedules, and crane plans, then commission setpoints, reset strategies, economizer logic, and alarms so your building runs as designed.
We align with Los Angeles Department of Building and Safety processes and coordinate inspections, Title 24 acceptance testing, and AQMD considerations. Our safety program covers rigging plans, traffic control, fall protection, and rooftop access protocols. You receive as‑builts, O&M manuals, equipment schedules, and training for facilities staff to ensure smooth operations after turnover.
Our mission is healthy air for healthier life. In high‑rise environments, that means consistent ventilation, effective filtration, clean coils, and well‑tuned control sequences. We implement demand‑controlled ventilation, MERV 13–16 filters where practical, UV‑C coil irradiation, and pressure monitoring to help reduce airborne particulates and maintain indoor environmental quality without excessive energy use.
#1 AC Guys is a fourth‑generation family business with 80+ years of engineering experience. Our team is factory‑trained by Fujitsu (Japan), Mitsubishi Electric (Thailand), Midea (China), Gree (China), and Haier (China). This multi‑platform training, combined with extensive field experience on Lennox commercial systems, equips us to navigate complex high‑rise constraints and deliver dependable, high‑efficiency outcomes.
We pair design decisions with lifecycle cost modeling, energy analysis, and utility incentive guidance to show payback clearly. Expect transparent pricing, phased implementation options, and retrofit strategies that minimize downtime and tenant impact. We align projects with available rebates and efficiency programs where applicable.
We serve Los Angeles County and nearby regions, including Orange County, Ventura County, and Western Riverside County. Our dispatch model supports high‑rise properties with priority response, stocked service vehicles, and technicians equipped to troubleshoot Lennox RTUs, VRF, and control systems quickly.
From the rooftop to the basement, we handle the details that make high‑rise projects succeed. Our team manages permits, coordinates trades, and maintains safe, orderly jobsites—so your schedule and budget stay on track.
