McMullen's Refrigeration and Heating Ltd was started in 1961 in a small residential garage in the Mountview area of Red Deer. Since that time our company has grown to over twenty four employees with three trades on staff. In the early years only commercial refrigeration service work was preformed. As word spread it wasn't long before the demand for heating service presented itself, followed by a demand plumbing services. Now McMullen's offers commercial refrigeration, heating and plumbing, while specializing in residential furnace change outs, residential plumbing service with our 'plumbing parts warehouse on wheels', and hot water heating upgrades.
