Commercial HVAC Installation & Repair in Los Angeles
EPA-certified commercial HVAC contractor with 40+ years serving Greater Los Angeles. We install, repair, and maintain rooftop units, VRF systems, and split systems for restaurants, hotels, office buildings, retail centers, and medical facilities — with same-day emergency response across LA, Malibu, Beverly Hills, Pasadena, Santa Monica, and the San Fernando Valley.
A failing HVAC system in a Los Angeles restaurant means the health department walks in and your kitchen fails inspection. In a Beverly Hills hotel, it means guests posting one-star reviews before checkout. In a Pasadena medical office, it means rescheduling patients. The cost of a broken commercial HVAC system is never just the repair bill — it's lost revenue, damaged reputation, and business disruption that you can't afford.
Arctic Cool Refrigeration has handled commercial HVAC for Los Angeles businesses for over 40 years. Our EPA-certified technicians work on every major system type — rooftop package units, VRF multi-zone systems, split systems, and chilled water plants — across every commercial building type in the region. We carry parts for Carrier, Trane, Lennox, Daikin, Mitsubishi Electric, York, Goodman, and Rheem, which means fewer return visits and faster turnaround on every job.
Commercial HVAC Installation in Los Angeles
Whether you are opening a new restaurant in Los Feliz, expanding a retail chain in Santa Monica, or retrofitting an aging office building in the San Fernando Valley, getting the HVAC installation right from day one determines how much you pay to operate that building for the next 15 to 20 years. Oversized equipment short-cycles and wears out faster. Undersized equipment runs continuously and never catches up on a 95-degree LA summer afternoon. Either mistake costs you money every single month.
Our commercial HVAC installation process starts with a proper load calculation for your specific building — square footage, ceiling height, occupancy, kitchen heat loads, server room requirements, and solar exposure all factor in. We size the equipment correctly, pull the required permits, coordinate with your general contractor or property manager, and handle all California Title 24 energy compliance documentation so you are not left scrambling at final inspection.
Commercial HVAC Systems We Install
- Rooftop Package Units (RTUs) — the workhorse of LA commercial HVAC. We install all tonnages and brands, including Carrier, Trane, Lennox, York, Goodman, and Rheem. Ideal for restaurants, retail spaces, strip mall units, and single-story office buildings.
- Variable Refrigerant Flow (VRF) Systems — Mitsubishi Electric, Daikin, and LG multi-zone systems that let different floors or zones run at different temperatures simultaneously. The right choice for hotels, mixed-use buildings, medical offices, and multi-tenant office buildings where every tenant controls their own zone.
- Ductless Mini-Split Systems — fast, flexible zoning for server rooms, wine storage areas, individual restaurant dining rooms, and retail spaces where running new ductwork is impractical or cost-prohibitive.
- Split Systems — separate indoor air handler and outdoor condensing unit configurations for mid-size commercial spaces, back-of-house restaurant areas, and retail stockrooms.
- Dedicated Outdoor Air Systems (DOAS) — fresh air ventilation and humidity control for commercial kitchens, healthcare facilities, fitness centers, and any high-occupancy space with strict indoor air quality requirements.
- Chilled Water Systems — large-scale central plant systems for multi-story office towers, hospitals, and industrial facilities in greater Los Angeles.
- Packaged Terminal Air Conditioners (PTACs) — individual room control for hotels, motels, and multi-unit commercial properties throughout LA and the San Fernando Valley.
Commercial HVAC Repair in Los Angeles
When a commercial HVAC system breaks down in Los Angeles — where summer temperatures regularly push into the 90s and 100s inland — you need a contractor who picks up the phone and shows up the same day. Not a national call center that schedules you a week out. Arctic Cool has been the same-day emergency repair option for LA businesses for over 40 years, and our technicians carry the parts and diagnostic equipment to resolve most commercial HVAC failures on the first visit.
We repair every major commercial system type and every brand currently running in Los Angeles commercial buildings. Our technicians are EPA-certified for refrigerant handling and trained on the full range of modern commercial HVAC controls — from legacy pneumatic thermostats in older Westside buildings to modern BACnet and Modbus building automation systems in newer construction.
Common Commercial HVAC Failures We Fix
No Cooling During Peak Hours
Compressor failure, refrigerant leak, or tripped breaker. Restaurants and retail stores in LA cannot wait — we prioritize same-day response for total system failures.
Rooftop Unit Not Keeping Up
LA's summer heat is brutal on RTUs. Dirty condenser coils cut capacity by 30% or more. We clean, recharge, and restore full tonnage output on-site.
Uneven Temperatures Zone to Zone
Hotel rooms, offices, and restaurants all suffer from zone imbalance. We diagnose duct leaks, failing VAV boxes, zone controllers, and VRF branch controllers.
Energy Bills Spiking Unexpectedly
Low refrigerant, fouled coils, failing economizers, or a mistuned building control sequence. We identify the efficiency loss and fix the root cause — not just the symptom.
Banging, Grinding, or Rattling Noises
Loose fan blades, worn bearings, failing compressors, or refrigerant flooding. Ignoring mechanical noise in commercial HVAC always leads to a larger, more expensive failure.
Musty Odors or Air Quality Complaints
Mold in drain pans, clogged condensate lines, or contaminated ductwork. Common in LA coastal properties and older buildings in Beverly Hills and Santa Monica.
VRF or Mini-Split Error Codes
Mitsubishi Electric, Daikin, and LG VRF systems display fault codes that require brand-trained technicians to diagnose and clear. We carry system-specific diagnostic tools for all major VRF brands.
Commercial Kitchen Hood System Conflicts
Restaurants in LA commonly lose cooling when kitchen makeup air systems are misbalanced. We calibrate hood exhaust, makeup air, and HVAC together — not separately.

Commercial HVAC Maintenance in Los Angeles
Most commercial HVAC failures in Los Angeles are preventable. Dirty condenser coils, low refrigerant charge, clogged drain lines, worn belts, and failing contactors all show up weeks before they cause a system shutdown — if someone is actually looking. The businesses that call us for emergency repairs in July are usually the same ones that skipped their spring maintenance visit.
Arctic Cool's commercial HVAC maintenance programs are structured around your building type, system age, and usage pattern. A hotel in Malibu with oceanfront salt air exposure needs different maintenance intervals than a Pasadena medical office with standard inland conditions. A restaurant with a commercial kitchen running 12 hours a day needs more frequent filter and coil service than a Beverly Hills retail boutique. We build the maintenance schedule around your actual equipment — not a generic template.
What Our Commercial Maintenance Program Covers
- Condenser and evaporator coil cleaning — the single highest-impact maintenance task for LA commercial HVAC. Dirty coils force the compressor to work harder, raise energy consumption, and dramatically shorten compressor life.
- Refrigerant level check and leak inspection — EPA-certified refrigerant handling. We document charge levels and identify leaks before they cause compressor damage or trigger regulatory issues.
- Electrical component inspection — contactors, capacitors, disconnect switches, and control boards. We replace components showing wear before they cause a failure during peak summer hours.
- Filter replacement and air handler cleaning — critical for indoor air quality in restaurants, medical offices, and any commercial space with health inspection requirements.
- Condensate drain line flushing — essential in LA coastal buildings where algae growth clogs drain pans and causes water damage to ceilings and walls.
- Thermostat and controls calibration — verifying that your building automation system or commercial thermostats are actually controlling the equipment correctly.
- Belt, bearing, and motor inspection — catching mechanical wear before it becomes a failed blower motor or seized condenser fan during a Calabasas heat wave.
- Priority emergency response — maintenance clients get priority scheduling for emergency calls, with faster response times than non-contract customers.
Businesses on a planned commercial HVAC maintenance program with Arctic Cool consistently see 15 to 25 percent lower energy costs compared to reactive-only service. More importantly, they avoid the lost revenue, customer complaints, and health department issues that come with an unexpected system failure during peak business hours.
