What reviewers praise

2 cited reviews
“The job was completed in 1 day, with terrific results. Everyone I dealt with throughout the process were extremely professional and eager to answer any and all questions. I have recommended them several times since they completed our boiler/water heater combo and will continue to do so with confidence.”
“the final product looks like something from a Jules Verne novel. Everything is left well mar”
Estimate process cited as fact-based rather than sales-driven; crew walked through system operation post-install and left no cleanup for the customer

“From start to finish our experience with JM Plumbing and Heating was top notch in professionalism, knowledge of products and options, responsiveness to email/texts, scheduling, and installation. Nick's visit to give us an estimate on a tankless water heater built our confidence and drove our decision to hire JM; he answered our questions and gave us facts, not a sales pitch.”
“Nick, the co-owner, came out and gave me a very reasonable estimate for a tankless water heater installation, compared to others. Nick is courteous polite and flexible. They did a very clean install and left me nothing at all to clean up. They walked me through the system after as well.”
Clean electrical/HVAC crossover work noticed by a neighboring homeowner who immediately hired the same crew for a panel/service-line upgrade

Nick, Ziad and Dimitri were great to work with. Recommend JM for electrical and HVAC work.”
“In December last year, we had old boiler and hot water tank removed and replaced with an on-demand water heater/boiler Combo unit by JM plumbing. I thought it was important to wait 6+ months before writing a review. The job was completed in 1 day, with terrific results. Everyone I dealt with throughout the process were extremely professional and eager to answer any and all questions. As a bonus we have a lot more …”
