Centerline Mechanical LLC

Our view at Centerline Mechanical LLC is that in order to get big results, you need to think smaller. And by smaller, we are talking about the attention to detail needed in order to keep a high efficiency heating and cooling system running at peak performance for years to come.
We purposely keep our staff size on the smaller end to maintain quality control that can sometimes be lost when companies have an abundance of installers. We take this quality control one step further by implementing two specified quality control visits per whole home heat pump installation. This ensures that every installation we complete is not only up to our standards, but more importantly will exceed yours.

Highly recommend their services!

Working with Centerline Mechanical for electrifying our home was nothing short of streamlined. They were very knowledgeable with the Mass Save process, and also with what equipment would best fit our home. We went with an Amana Cold Climate central Heat Pump and our house has never been more efficient, quiet, and comfortable. And the best part is our $10,000 rebate came right on time, I highly recommend their services!
