Family-Owned HVAC Experts with 80+ Years of Engineering Excellence

Our Legacy and Commitment

As a 4th-generation family business, United Generator & Power brings unmatched engineering knowledge to every project. Our story began more than 80 years ago, when the first engineer in our family inspired a tradition of excellence. Today, we continue this legacy by combining advanced training with modern HVAC technologies to ensure the highest level of comfort and reliability.

Commercial HVAC Expertise

Why We Stand Out

Our engineers are factory-trained by industry leaders — Fujitsu, Mitsubishi Electric, Midea, Gree, and Haier. This direct manufacturer training means that we understand each system at the highest technical level. Combined with decades of engineering experience, we deliver solutions that go beyond basic installation and repair.

Key reasons clients choose United Generator & Power:

• 4th-generation family of engineers with 80+ years of expertise.
• Extensive experience in both residential and commercial projects.
• Specialized knowledge in large and complex HVAC systems.
• Commitment to healthy indoor air for a better quality of life.
• Service areas covering Los Angeles County, Orange County, Ventura County, and Western Riverside County.

Our Mission: Clean Air, Healthy Life

We believe that HVAC is more than just temperature control. It is about creating an environment where families and businesses can thrive. Clean, fresh, and properly circulated air promotes better health, greater comfort, and improved productivity. Every system we design, install, or service is guided by this mission.
