Expert service, repair, and preventive maintenance for commercial chiller systems across Long Island. All Seasons technicians are experienced with air-cooled and water-cooled chillers for office buildings, medical facilities, data centers, and large commercial properties.
Commercial chillers are large-scale refrigeration systems used to cool buildings that are too large for conventional HVAC equipment. They circulate chilled water (or refrigerant) through air handling units and fan coil units to cool entire buildings or multiple zones simultaneously.
All Seasons technicians are experienced with all major commercial chiller types — providing service, repairs, startups, and preventive maintenance contracts for Long Island properties of every size.
Reject heat directly to outdoor air via condenser coils and fans. Common on rooftops and mechanical areas. Lower installation cost, easier maintenance — the most prevalent chiller type on Long Island commercial properties.
Reject heat via cooling towers and condenser water loops. More energy-efficient for larger buildings but require more complex infrastructure. Common in large office buildings, hospitals, and data centers.
Smaller, self-contained units used in process cooling applications, server rooms, labs, and medical facilities. Require precise temperature control and reliable uptime — All Seasons handles these with the same care as large central plant systems.
Fast diagnosis of chiller failures — compressor issues, refrigerant leaks, condenser problems, controls failures, and more. We carry common parts and can resolve many issues in a single visit.
Scheduled maintenance programs for commercial chiller systems — including refrigerant checks, oil analysis, coil cleaning, controls calibration, and full system performance testing. Documented records provided after every visit.
Spring startup and fall shutdown procedures — including safety checks, refrigerant verification, controls testing, and documentation — to ensure your chiller operates safely and efficiently at the start and end of each cooling season.
When repair is no longer cost-effective, we help you evaluate replacement options, specify the right equipment for your building, and manage the installation process — minimizing disruption to your operations.
Our technicians are experienced with all major commercial chiller manufacturers. Whether you have a legacy system or recently installed equipment, we have the knowledge and tools to service it properly.

A commercial chiller is one of the most expensive pieces of HVAC equipment in your building. Preventive maintenance contracts protect that investment — reducing emergency repair costs, extending equipment life, and keeping your building comfortable year-round.
All Seasons designs service agreements around your chiller system's specific requirements — manufacturer specifications, usage patterns, and your building's cooling season. We handle the scheduling and documentation so you don't have to.
