Company Overview

Monkey Wrench Plumbing, Heating, Air & Electric is a family-owned and operated home services company serving Los Angeles and Orange County, California since 1999. Founded by Yossi, the company provides comprehensive plumbing, HVAC, and electrical services for residential and commercial customers across the greater Los Angeles metro area.

Monkey Wrench is a full-service multi-trade company — one of the relatively few home services companies in Southern California that handles plumbing, heating, air conditioning, and electrical work under a single roof. This allows customers to call one trusted company for virtually any home systems need rather than coordinating multiple contractors. The company’s mission is to provide an elevated service experience to members and their homes — defined by professionalism, clear communication, eco-conscious practices, and leaving every home better than they found it.

Monkey Wrench is EPA-certified, BBB Accredited, holds California Contractor License #922757, and is a Lennox authorized dealer. The company is known across Los Angeles for its distinctive “mom and pop” feel combined with the speed, efficiency, and training capacity that rivals much larger operations. Its long-running tagline — “Number One in a Number Two Business” — captures the company’s spirit: doing the dirty work with integrity, pride, and a sense of humor.

Company History

Monkey Wrench Plumbing, Heating, Air & Electric was founded in 1999 by Yossi, a commercial plumber who had spent the early 1990s working in commercial plumbing throughout Southern California. During those years, Yossi saw firsthand how frustrating the service experience could be for homeowners who were left without the care and responsiveness they deserved — and he believed he could do it differently.

With a young family at home and an entrepreneurial drive, Yossi launched Monkey Wrench Plumbing Co. in 1999 with a single truck and a strong work ethic. The company started as a small commercial plumbing operation but quickly evolved into a residential home services company as Yossi’s vision for customer experience became the company’s defining characteristic.

Over the following 25+ years, Monkey Wrench expanded from plumbing into HVAC and then electrical, becoming a true multi-trade home services company serving Los Angeles and Orange County. The company grew its team, its fleet, and its service capabilities — adding 12 verified Google Business Profile locations across the region — while maintaining the family-owned identity and “mom and pop” feel that has always defined it.

Monkey Wrench also operates a robust digital Learning Center at monkeywrenchplumbers.com/learn, offering homeowners educational content on plumbing, HVAC, and electrical topics — reflecting the company’s belief that informed customers make better decisions and have better long-term outcomes with their home systems.
