Heating & Cooling in Phoenix, AZ

Your Phoenix heating & cooling team

LJ Refrigeration Co. serves Phoenix homeowners with air conditioning, heating, heat pump, and ductless mini-split service. We're a third-generation family company founded in 1963, and our own shop sits right here in North Phoenix — this is home turf.

What Phoenix homes ask of a system

Phoenix has the widest range of housing stock we work in — 1950s and 60s ranch homes in the central corridor, 1970s-80s construction spread through the northern neighborhoods, and newer builds further out. Older homes often still carry their original ductwork and undersized electrical panels, which means a straightforward-looking AC replacement can turn up code items a newer home would never have. And because Phoenix's dense urban core runs hotter than the surrounding desert during summer — the well-documented "heat island" effect — equipment downtown and in older neighborhoods works under even more strain than the metro average. We size every system for the house it's actually going into, not a rule of thumb.
