Chris installed duct work for a new heating and cooling system in our two story home. I am very pleased with the work he did and the manner in which he completed it. He took the time and effort to plan and map out each vent, working with me to ensure that I was okay with the location before holes were cut. His experience and attention to detail were greatly appreciated. I strongly recommend Chris.

Chris of CMC crafted our new duct work for both our basement and upstairs air handlers. He was a pleasure to work with, extremely professional and knowledgeable, and did an excellent job. I can't recommend him enough for all your duct work needs.

I had my 20 year old home updated with central air, and it was not an easy job. Chris handled the situation professionally. He explained how he did things and what we had to do to be prepared for his installation, I never was left guessing what was happening. He was clean, prepared, and honest, and I would highly recommend him - and I LOVE my new system!

Chris was a pleasure to work with. He did exactly what we agreed upon and more. His quality and attention to the custom nature of each project was spot on. This was our first project with Chris and it will not be our last. Being in the construction industry it is always a relief to find someone who takes great pride in their work, CMC Sheet Metal delivers just that.

We moved into a new house recently and hired Chris for two projects. The first was to reroute an air return that was inefficiently located in the back of a bedroom closet. Chris installed new ductwork to move the return into the adjoining bedroom, and was able to custom-fit it into the corner of the closet so the majority of the space could remain available to use for storage.
The second was an issue with our oil furnace: on the exterior of the house, the exhaust from the furnace and the air intake were located too close together, so the intake was pulling in some of the exhaust and circulating

We recently hired Chris to address some problems we had with our HVAC system. He was great! He was very responsive and came right over to access our problems. He wrote up a very detailed estimate of what he would do to fix the situation. Then he came and did a fabulous job on-site. There was no mess. The quality of his work was impeccable! I thought that his quote was very reasonable. I wish we had more problems so that we could have him come again! I would highly recommend him.
