Sierra Valley Mechanical Story:

The story of Sierra Valley Mechanical begins in 2002.  After working for a decade in the HVAC trade for one of the “Big Guys” in town, Michael Hlavay founded the business under the original name of Sierra Valley Home Corp.  A guest room in Mike’s house was transformed into a home office and a 1970 Dodge truck became the service and installation fleet vehicle.  While continuing to provide quality HVAC services, Mike's passion for building also led to the construction and remodeling of numerous custom homes, condominiums, and small commercial projects.

Over the next few years, the company and staff quickly grew out of its humble surroundings and Sierra Valley was moved to its current commercial building. The trusty old Dodge was allowed to retire and a shiny new service van and flatbed took its place.

In 2007, the Great Recession started to show its face and the situation became “survival of the fittest” for small businesses everywhere.  With almost no demand for construction services Mike focused on growing the heating & air conditioning division and began learning about solar.  Having broad knowledge of the “whole building” and specialized knowledge of the HVAC trade, Sierra Valley was able to offer expert services to both residential and commercial customers.

With a renewed focus on HVAC and related trades, it eventually became clear that “Sierra Valley Home Corp” no longer seemed the best name for an HVAC/Solar company.   In 2020, we officially became Sierra Valley Mechanical.  Same license, same great people and the same great company our customers have grown to know and trust.

Sierra Valley Mechanical experienced humble beginnings and has endured challenging times.  Ultimately, Sierra Valley has remained a stable and thriving small business in our community.  Through the years we have enjoyed supporting and contributing to the livelihood and expertise of our employees, many of whom have been with us over five years and some over thirteen years.  Mike's daughter has also joined the family business, but you could argue that all of our employees are like family.

Everyone here takes pride in being a company that continually strives to provide honest and ethical services.  Our technicians are paid hourly and we avoid any compensation structure that creates incentive to inflate repair bills or make unneeded recommendations. You will never get any sales pressure from us; just honest and professional recommendations and quotes. Just like finding that trusted auto repair garage, we strive to be that kind of company for all of your home comfort needs and services.
