HVAC Services in Key West

Sub Zero Inc. provides a wide range of HVAC services, ranging from consultations, initial installations, start-ups, repair, maintenance and warranty work. We work on a variety of air conditioners, chillers, ice machines, commercial refrigerators and freezers and heat pumps.

Quality Service and Product

At Sub Zero Inc., all of our technicians are trained and certified to work on your equipment. Our technicians are EPA certified and have taken the standard EPA courses. We work on almost all makes and models of air conditioners, ranging from Trane, Carrier, Ruud, Rheem, Mitsubishi, Hoshizaki, Manitowoc, Lennox and Goodman. Unfortunately, we do not work on window units. We try to provide the best equipment and parts available on the market, whether it be a motor, thermotstat, filters or an expansion valve.


We are licensed and qualified to work with various refrigerants including; M-99, R-12, R-22, R-134A, R-404, R-409 and R-422D. These chemicals are a necessity in our field but also harmful to the environment when not properly handled and maintained. Knowing this, we strive to be as eco-friendly as possible, always recovering all refrigerant from units using certified recovering methods. All our recovered refrigerants are then delivered to a refrigerant recycling plant.
