CNM Heating Cooling Piping LLC

I highly recommend CNM. Im extremely pleased with the mini split system they installed. Mark, Cody, Ethan, and Dylan are true professionals. They were on time, efficient, and extremely friendly. Installation was immaculate! They are more than willing to take their time and explain/educate you on what will adequately meet your home needs. 5 star company!

Thanks CNM!

We had CNM install a Fujitsu Mini-Split system in our home and we couldn't be happier. Mark and his crew were super professional and were meticulous about all the work. I especially appreciated that Mark took great thought and care about how he would direct the outside lines to blend in as much as possible. Every worker was respectful and kind and even though it was a larger job, it was super organized and installation was a breeze. This is a 10-star business and I'm so glad I found these guys. CNM is a top-rated company for a reason. They are simply the best.

CNM was incredibly quick to come help with my AC issue. In no time I was back up and running, just in time for the hottest day so far. Cody was extremely polite and professional, happy to explain everything he was doing as he worked. Will absolutely be using CNM for all my heating and cooling needs from now on!

Cody, Mark and their crew perform quality work from start to finish. They are always personable, professional and respectful to my family and my property. They treat me as if I was their only client. When it comes to heating and cooling efficiency, Cody has the knowledge to design a system that will best fit your needs. Nothing more nothing less. Thanks again guys!

I've worked with CNM for my home heating oil delivery, a home furnace repair, (that other companies couldn't figure out,) my rental property expansion, and a commercial air conditioning project. Each and every time I've been extremely pleased with the speed, professionalism, cost, and quality of their work. I've been working with CNM for probably five years now and have seen their rapid expansion. Each new hire is a positive addition, from their new driver to their secretary, they say it's a great to work with them. A+ from me.

Mark and his team were right on time and did a great job in a timely manner replacing our whole house A/C system. They even hauled away our old system free of charge. AA++ service. Great communication. Highly Recommended!

Mark of CNM has helped us out on a number of occasions on both routine maintenance/repairs and emergencies. He came to our house at 2 am last week to shut off our water after the deep freeze froze some of our pipes. He is professional, courteous and knowledgeable. I have been looking for a good heating and cooling guy for 25 years. I finally found him.

(1) revision of existing oil/baseboard hot water system
(2) installation of 12000 BTU minisplit in large room over the garage
(3) installation of heat-pump assisted electric hot water heater, replacing the existing coil-in-furnace type hot water heater.
All this took place more than a year ago and it has worked very well. We are very pleased with CNM's work!

Super: responsive, professional, fair, polite and of course effective. Good experience. No problems. Would (will) recommend highly.

CNM installed a central air system and replaced my ancient boiler last spring. The work was completed in two days. The crew was friendly, knowledgeable, respectful, and efficient. I was impressed with every step - from obtaining the quote (with which they also recommended financing options available through Energize CT), to the installation, and all communications thereafter. My central air and heat pump system is amazing, and my new boiler is easy on the eyes and way more efficient than the dinosaur they removed.
