Commercial split systems—pairing an outdoor condensing unit with an indoor air handler—offer versatile climate control for offices, attics, mechanical rooms, and drop-ceiling applications. Heat pump models feature reversing valves that seamlessly switch refrigerant flow between cooling and heating modes, offering efficient climate control in every season.
At Blizzard Mechanical, we service, repair, and install commercial split systems and heat pumps ranging from 1-ton light commercial setups up to hundreds of tons across complex facility layouts.
Because heat pumps and split systems work double-duty through summer heat and winter cold, scheduled upkeep is essential to avoid unexpected system failures.
We carry extensive hands-on experience with Trane, Carrier, Lennox, York, Johnson Controls, and Daikin.

This Plan and Spec project was awarded to us by the Town of Waterford. The scope included removal of a decommissioned unit and replacement of this 12.5-ton York RTU.
Design Build project for the University of Bridgeport. The school converted 4 racquetball courts into an exercise gym and spin room. We installed a 14-ton Mitsubishi City Multi Heat pump system with cassette indoor units serving the exercise rooms, hallway, and offices. This project qualified for a $39,990 rebate through EnergizeCT.
Design Build project for the University of Bridgeport. The school converted old dormitories into offices for the School of Nursing. We removed existing radiant convectors and tied into the hot and chilled water systems to install 5 new MagicAire units and a Fantech ERV system for fresh air. This project also involved running new 2” chilled water mains to service the new units.
Design Build project for the University of Bridgeport. The school converted the former print shop into a welding school. We installed 3) Trane RTU’s, ductwork, provided the steel and roofing contractors, and also installed a RoboVent particulate filter system with 16 stations and a hood for the plasma table. In addition to this we installed all of the compressed air and welding gas piping.
Design Build project – we installed a Mitsubishi computer room a/c unit to cool UB’s new AI supercomputer. These units have built in humidifiers and electric heat for precise temperature and humidity control in highly sensitive environments.
Design Build project we were awarded by the Town of Seymour. We installed a 14-Ton Mitsubishi City Multi system with a cassette indoor for the hallway and 4) concealed ducted air handlers serving various town offices.
Plan and Spec project we were awarded by the Milford BOE. This project involved the replacement of 4 RTU’s. We submitted a design change to relocate and install the proper curb for the 15-ton unit in lieu of a curb adapter, which was accepted.
Plan and Spec replacement of a cooling tower and 3 water source heat pumps awarded to us by the Town of Groton. Blizzard mechanical was Prime Contractor on this project and facilitated all of the electrical, welding, rigging, and insulating.
Design Build project – we installed a Trane dual fuel heat pump RTU for Elm City Trailer’s new showroom. This project included ductwork, gas piping, roofing, and steel work.
New construction 92-unit apartment building. We installed Mitsubishi high efficiency ducted heat pumps in all of the apartments, and ductless units in the common areas. We also installed the dryer vents and bath fan piping.
We removed a 50+ year old water cooled air conditioner and installed a high efficiency Mitsubishi Heat Pump system for heating and cooling.
Our mission is simple: keep your facility running smoothly so you can stay focused on your business. We know HVAC and plumbing issues don’t just cause inconvenience — they impact productivity, budgets, and safety. That’s why we take a proactive approach, focusing on prevention, efficiency, and fast resolutions when issues do arise.
We aim to be a true partner for facility managers, property owners, and business operators by delivering practical solutions that lower operating costs and reduce unexpected downtime. From preventative maintenance to emergency repairs and full system replacements, our team prioritizes clarity, reliability, and long-term performance. When we’re doing our job right, your building works exactly as it should — quietly and efficiently in the background.
For systems providing both heating and cooling, maintenance should be performed biannually or quarterly. Cooling-only systems require service at least once per year.
Turn off the system if unusual noises or freeze-ups occur, and contact a qualified mechanical contractor. Ensure building maintenance personnel know where system power disconnects and supplemental fuel shut-offs are located.
Ensure long-term efficiency and reduced operating costs. Contact Blizzard Mechanical at (203) 735-BLIZ today.
