Caledonian Mechanical, Inc. brings seasoned, practical HVAC/R expertise to Fresno County and the Central Valley. Founded more than nine years ago by Christopher Campbell, Caledonian combines a lifetime of hands-on trade experience with a disciplined, customer-first approach. Christopher’s 30+ years in the HVAC/R field — working on systems in the U.K. and across the United States — shape the company’s technical skill, attention to quality, and commitment to practical, energy-smart solutions.
Why “Caledonian”?
The name Caledonian draws from history: the Romans used the name Caledonia to describe the land and peoples of what is now Scotland, and “Caledonians” referred to the tribes who lived there in the 1st century AD. The name evokes durability, tradition, and craftsmanship —qualities we bring to every job. Like the skilled artisans and builders of earlier ages, Caledonian Mechanical values solid workmanship, careful inspection, and solutions that last.

Our service philosophy
Caledonian’s approach is straightforward: diagnose clearly, recommend honestly, and deliver reliable work without aggressive up-selling. We focus on three outcomes for every customer — safety, longevity, and efficiency — using a three-stage system that identifies immediate concerns, corrects deficiencies, and optimizes equipment for lower kilowatt-hour usage over the long term.
Real Feedback. Real Clients.

When our HVAC started making loud banging sounds, we panicked and called them. In less than 30 minutes, Christopher was at our Sanger property and fixed the fan motor. Best part? He didn’t recommend a whole new unit like some others did.
Javier L. -
Getting ready to sell our place in Sanger, so we had these folks come do an HVAC inspection. Christopher showed up right on time, gave the system a full check, and explained everything without a bunch of jargon. The report was super helpful!
Phyllis P. -
James was awesome! He really took the time to make sure everything with my HVAC system was running smoothly.
Jonathan E. -
We own a yoga studio in Sanger and can’t afford temperature issues during sessions. Caledonian Mechanical Inc. rebooted our AC unit so it won't cause any hiccups.
Lindsey F. -
Off-grid homes like ours often get a shrug from city-based HVAC companies. Not these folks. Christopher respected the solar system limitations and recommended an energy-efficient mini-split.
Henry P. -
We had two AC units that just stopped working. Chris came out, got one running again, and replaced the other one—fast and hassle-free. I love that Caledonian doesn’t try to push unnecessary repairs or overcharge like some companies do.
Robert R. -
Great experience with Christopher—he knew exactly what he was doing and took time to explain each step of the repair.
Michael E. -
Our toddler has asthma, and air quality is a big deal in our Sanger home. Christopher did a full filter upgrade and airflow assessment.
