About Us

Our Story

Jeff Yrigoyen

President

Jeff Yrigoyen, a California native resident born in 1969, began his career in the family roofing business in 1983 at the age of twenty-seven, worked his way up and eventually became the President of the company in 1992. In 1987, he attended and graduated from HVAC trade school, and by 1997, he had earned his Hvac contractor’s license and in 2000 obtained his Plumbing contractor’s license. From 1995 to 2000, Jeff worked for one of the largest boiler companies in Southern California, where he worked in the field, ran boiler installations, and assisted co-workers with daily and emergency 24 hour a day complex boiler diagnoses and repairs. In 2000, driven by a desire to bring a higher quality of service to the HVAC industry, he put his full dedication and time into the family Hvac business, Westcal Mechanical, Inc. His commitment to excellence has driven the success of Westcal Mechanical, Inc., establishing him over the last 28 years as a trusted professional in the HVAC industry.

Jacob Yrigoyen

Operations Manager

Jacob Yrigoyen, the son of Jeff Yrigoyen, pursued his passion for HVAC by attending Brownson Technical Institute at the age of 18. Graduating at the top of his class, Jacob quickly rose to become a lead technician under his father’s mentorship.
In 2016, Jacob transitioned into education, taking a teaching position at a local trade school. His exceptional ability to train future HVAC technicians led to his promotion to Program Manager in 2017. Over the next five years, Jacob transformed the program, elevating it from 16th to 3rd place nationally in retention and successful graduations.

By 2022, Jacob was offered the prestigious role of Program Administrator, involving curriculum development and support for campuses nationwide. However, he chose to stay local, prioritizing his family – his wife Lauren and their two children.
In 2023, Jacob returned to the family business, where he and Lauren are now integral to its operations, continuing the legacy of excellence in HVAC services.
