I would recommend CMS to anyone interested in upgrading their current heating system. I went from an ancient and expensive oil heater to a Geothermal system. I have already seen huge cost savings and expect the system to pay for itself within the next few years. From beginning to end Ed Conn and his team did an excellent job. True professional's in their field.

Thank you to Conn Mechanical for getting our new heating units in before the cold weather sets in. They were so patient to work around our busy schedule. Ed worked with us to make the changes we needed to make them more efficient. Kait in the office made sure everything flowed smoothly. Kenny, Greg and Eddie worked well together to make sure the job was done in a timely manner.

We have used Conn Mechanical since 2011. Ed Conn and his team provided us excellent advice for replacing our Water Furnace Geothermal Unit with a new high efficient Bosch unit for our home in 2011. The response, professionalism, service was outstanding. Now in 2018 our second Geothermal unit failed at the end of the summer. Conn's team was extremely helpful and responsive in finding temporary solutions. They then researched the best solution to replaced our failed unit with a new high efficiency Bryant unit. The installation required some unique design in the duct work to adapt to our existing system. Conn's team was extremely professional in the installation. Conn's team provides a high quality service and stands behind their products to support their customers. We highly recommend Conn Mechanical for quality service!

Conn Mechanical is the "best" HVAC specialist team in all of South Jersey. Their diagnostic ability, implementation plan to remediate your problems and expedient manner in which they arrive and finish the job is exceptional by any standard. They are all outstanding in their performance and when the job is finished there is no negative traces such as clean up scenarios that they were even there! My thanks and recommendation for their services is unconditional.

I cannot say enough good things about this company. I called for an estimate for a new hot water heater when I saw on the SJ Gas site that Conn Mechanical is an authorized installer. The next day the owner of the company came out to give me an estimate. While he was there I had inquired about a ductless air-conditioning system. Ed was happy to measure and to give me an estimate for that as well as discuss financing options. Eddie P. and crew did a FANTASTIC job with the installation. They encountered unforeseen challenges with the install, but the problems were no match for these guys! The team was incredibly neat and clean. There were no unnecessary holes in the walls and no debris left behind. After the install was complete the team came in to start the system and then the owner came out and also inspected the system. Ed took the time to show me how to use the remote controls. He also reviewed all of the energy efficiency rebate paperwork with me. Kait, in the office, was nothing but helpful. She kept in constant contact with me either via email and/or phone. Kait has the most pleasant demeanor of any office worker I have ever met! The permit paperwork was perfect. I HIGHLY recommend Conn Mechanical. They are professional, talented, knowledgeable and personable.

Ed and his team was excellent to work with from start to finish. They came out on a day's notice on the hottest day of thesummer when my HVAC failed and executed a full replacement in under a week. His staff was cortious, professional and the install was of the highest level of workmanship. I would recommend Conn Mechanical with out reservation.

Ed and the folks at Conn are great. They came to repair my air conditioner the same day I called and ordered my new one the next day and installed it the day after that. I couldn't have asked for better service. Ed provided with me three options to choose from good, better, best and as well as a few different payment plan options. They went above and beyond to assist me and communicate via email and text. The technicians Eddie and Kenny were great. They were super quiet and polite in my house. They showed me everything and Ed stopped by the next day to check on the job and show me some of the controls and features of my new system and thermostat. He even walked me through the online setup. I have used Conn before to purchase and install a hot water heater and they also service my furnace. Their techs are always professional and knowledgeable and their service is awesome.

Great service, high quality work. We've used them for smaller jobs before. This time it was a major project: replacement of our 23-year-old geothermal systems. Special thanks to Mikey, Eddie, Nick, Kenny, and Greg, who spent a lot of hours in the crawl space under the house and in the attic; to Kait in the office, who kept everyone informed, and of course to Ed Conn, who is a pleasure to work with.

The Conn's were great, had to call them on a weekend and they got back to me in a reasonable time. Ed was very knowledgeable and helpful. We chose to get the tankless hot water heater, and it was installed the next weekday. The guys knew just what they were doing and the project was done quickly. We are still waiting on the permit, but we are very happy with the water heater and installation.
