ModCon Service & Support, Inc.

I had a great experience working with ModCon services. Bret Chisholm helped me out of a real jam with a faulty boiler in one of my investment properties. They showed up on time, they were very polite and informative. I plan on using them for all my properties.

So I was a new home owner in central MA. Leominster to be specific. I was highly recommended to modcon for servicing Navian tankless water heaters. They came in August 2023 and told me everything was fine while also trying to pitch a new install. Ok cool, it is 6 years old, but come on. Pitch a new install at the first service. Long story short. I turned on my second zone/floor as we finally received cold weather in January. Everytime my second floor would run, I was expriencing banging and water in my basement. So I called them to take a look. All of a sudden, they do not work on navians now. They told me to kick rocks. I called another local company. They came and fixed the issue in 30 mins, it was a faulty expansion tank.

I strongly suggest to not use this company. They missed my faulty expansion tank and they falsely advertise which make/models they actually can provide service to. ​
