A-1 Guaranteed Heating & Air, Inc. is a family-owned and operated HVAC business that serves residential clients in Solano, Contra Costa, and Napa Counties. The company installs, replaces, repairs and maintains a wide variety of HVAC systems, including furnaces, evaporator coils, compressors, vents and ducts. One of the first electrification contractors in California, A-1 Guaranteed has also partnered with Energy Upgrade California to increase its customers’ overall energy efficiency and achieve even greater savings by upgrading their homes. Currently, the company has been converting homes to Zero Net Energy homes, resulting in major utility savings and in some cases even eliminating the electrical portion of the bill.

Owners Richard and Krissy Hiteshew established A-1 Guaranteed Heating & Air 28 years ago, and they’ve since expanded to serve thousands of Bay Area customers. The company’s efforts have also translated to community recognition—it has received 17 awards for “Best HVAC Company in Solano” from the Vallejo Times-Herald, the “Spirit of Solano” award and KRON 4’s coveted “Best of the Bay” award for four years.

A-1 Guaranteed Heating & Air is a factory-authorized dealer of Bryant, Coleman, Fujitsu and Bosch HVAC systems. A new “Kasey’s Klub” membership program was created in 2017, which offers discounts and optional levels for the maintenance of existing HVAC systems.
