Mason Heating & Air Conditioning

Ongaro and Sons Plumbing, Heating and Cooling was established in 1932 by Ernest V. Ongaro (that's two years before the Golden Gate Bridge was opened!) and we have been proudly serving our community ever since. Our goal is to provide the highest level of service and value in the industry. Today, we have third generation family members working hard to carry on the family tradition of providing our customers with quality workmanship and exceptional service. We maintain a steadfast commitment to employee education and development. Careful attention is made to protect our customers' property during all phases of the installation. We strictly follow applicable codes, manufacturer recommendations and industry standards in all our installations. We provide parts and labor warranties that go beyond industry standards. We maintain an excellent safety record with weekly meetings on a wide range of safety topics. As factory authorized installers, we are trained to provide the most current installation and service procedures. We are fully insured which includes worker's compensation and full liability insurance. Along with a full heating and air conditioning service department, we also provide service for plumbing, drain cleaning and leak detection.
