A.O. Reed has over 110 years to perfect our craft in Southern California. We have learned the “tricks of the trade” and have passed this knowledge down from generation to generation. A part of A.O. Reed’s success is the ability to be the best mechanical contractor in various markets. We pride ourselves on having a diverse project portfolio ranging from constructing state-of-the-art hospitals, labs, amusement parks, hotels, and high-rise office buildings. Our company is involved in every part of the project stage from pre-construction, fabrication, and installation. We have a skilled crew that has perfected techniques to provide the best HVAC, plumbing, and process systems. Once the project is turned over to the client, A.O. Reed’s service team maintains the systems and equipment. This “cradle to grave” method allows our team to create long-lasting client relationships.
