Working with CTC Mechanical Contractors was a seamless experience from start to finish. The team removed our old units and installed new  quickly, professionally, and with minimal disruption to our operations. The new system is running flawlessly — quieter, more efficient, and already reducing our energy costs. We couldn’t be happier with the results and highly recommend CTC Mechanical for any installation or upgrade projects.
