About Us

Altamont Mechanical is owned and operated by Sam and Karen Aranda. Based in Tracy, California we service residential and commercial customers throughout the Central Valley and Tri-Valley areas. With over 25 years of experience from serving small residential package units to large industrial and commercial systems.

Here are testimonials from some of our satisfied customers:

“One cold day in November, we thought we smelled fire in our house. Turns out it was our gas furnace which had caught on fire. It had become a safety hazard and had to be replaced. When my home warrantly company told us that they would only be covering
approximately $400 out of the $4,000 that it would take to actually cover all the equipment and labor, we knew we needed to call Karen and Sam. They sat down with us and walked us through the entire process. They were able to save us thousands of dollars and replace our old furnace with a quieter, more energy-efficient model. Sam
has so many years of experience doing this work. I highly recommend that you call them when you find yourself in a similar situation.”

 “I have been in the Real Estate industry for over 10 years and have worked with many different Heating and Air Conditioning contractors. When it comes to referring contractors to my clientele I am very selective and cautious in doing so. When it comes to Altamont Mechanical I can freely do so as I know Samuel will stand behind his work. I have referred Samuel to several of my clients and he has provided great service with exceptional knowledge of his industry. You can be rest assured that Altamont Mechanical will stand behind their work and deliver exceptional service.”
