Claim This BusinessC&N Mechanical LLC is a licensed HVAC contractor based in Round Rock, Texas, serving the Greater Austin area since 2015. The company holds license number TACLA63905R and has earned a 4.9-star rating across 38 customer reviews. Leonel, the company's lead technician, handles both residential and commercial heating and cooling projects, offering installation, service, and repair for all major HVAC brands.
What distinguishes this contractor is their breadth of commercial refrigeration expertise alongside standard heating and cooling work. The company repairs walk-in coolers, freezers, ice machines, and self-contained refrigeration units, equipment most residential HVAC companies avoid. They also offer preventive maintenance programs designed to extend system lifespan, plus emergency service for urgent breakdowns. All work is performed by licensed technicians with documented expertise in troubleshooting complex mechanical systems.
Local homeowners consistently highlight the same technician: Leonel. One reviewer describes how he arrived on a hot Texas afternoon within 48 hours of her AC failure, worked on his day off to complete the job, and even installed a code-required breaker that fell outside the original warranty scope, without being asked. Another customer notes Leonel took time to explain how her heater operated, walking her through components and maintenance. These accounts reflect a contractor who treats each service call as an opportunity to educate customers while solving genuine problems.
All 38 reviews award 5 stars, with every named testimonial praising technician Leonel specifically. Multiple reviewers mention emergency or same-day service during extreme heat conditions, and no negative reviews appear in the available sample.
