A Roseville Heating and Air company that was established in 1990 offering Roseville and surrounding area's HVAC repairs, sales, service and maintenance. We have always been family owned and operated. In the early years there were three generations working together to establish the business. Today Diamond Heating and Air is owned and operated by husband and wife team Robert and Elaine Weatherford.


Robert comes from an industrial background. He started his career working in saw mills after graduation from school. He became a millwright/electrician. After a 10 year career in saw mills Robert went to work for E & J Gallo Winery as a electrician and was promoted to the Plant Electrical Superintendent’s position for Gallo Fresno Operations until 1990 when he elected to become a contractor.

In 1990 Robert moved to Sacramento and started his own Roseville HVAC repair company which today is Diamond Heating and Air.

Elaine comes from a financial background. She was born and raised in Sacramento and worked for many years as a finance manager for Norwest Financial. She and Robert were married in 1998 and she has become an integral partner and manager at Diamond Heating and Air.


As a Sacramento Heating and Air company that is based in the Roseville area, we have served the Sacramento/Roseville Community for the past 20 years. Robert oversees all field operations and sales, while Elaine oversees the daily office operations and customer service.


At Diamond Heating and Air, both Robert and Elaine have committed themselves to selling a quality product, doing quality service and installations, and making customer satisfaction their number one priority. Our policy is “treat the Customer, their Home and their Possessions as you would treat your own”. We give each and every customer our full attention and address all your needs and concerns personally.
