"Danny, from HL Bowman, quickly understood the scope of the installation and used his expertise to make the installation seamless. As a result, the filtration system he installed is now operating perfectly to remove particulates greater the 5 microns from our well water. I would highly recommend HL Bowman for your plumbing needs. "

"Dylan was amazing. My hvac person retired & I found Dylan when my Central air decided to act up. He explained my unit was in approaching its last days but he could attempt to repair it if I wished but I decided it was time to do a complete new heating & cooling system & he made it a easy process. No pressure & no stress. Now we’re ready for the heat wave that’s apon on us. Thank you Dylan & your team for your professionalism & great service. I highly recommend & they’re my go to for plumbing as well as I’m about to have them replace my hot water tank before it becomes an issue"

"The installers were great, removed the 70 year old crumbling boiler and all the old valves, expansion tanks etc. and installed the new boiler and hot water tank in just 2 days. They explained what each valve and control did after they finished the installation. No extra charge for removal of the old equipment and they left the basement cleaner than when they arrived."

"Everyone I spoke to at Cotti-Johnson from the estimate through to installation of my generator were polite, professional and a pleasure to deal with. At the outset, the scope of the project and its cost was explained to me in simple and understandable language. The installation took place precisely on schedule and was completed within 3 hours. I received the necessary follow-up calls from the office to ensure the work was done to my satisfaction. I couldn't be happier with Cotti-Johnson."

"Paul was a great find! He was very professional and knowledgeable. He communicated with us well throughout the planning and installation process. He took time to understand our individual needs and completed the project to our complete satisfaction! I have already recommended him to several people already and I have only had my AC in for 2 weeks!"
