"Very professional, high quality work"
Brendan K. in July 2021
"Quick and Efficient. Came out the next morning, removed the broken water heater, installed a new one and gave us a quote for a boiler replacement, all in less than 2 hours. Price was reasonable considering it included the cost of the unit, labor, removal and disposal of the old unit and all this being an emergency during the holidays and Covid."

"I hired Marcin & his team at Precision Plumbing & HVAC for multiple projects. First to handle all plumbing in a gutted bathroom renovation, then to replace an old gas water heater and furnace with a new high efficiency combi boiler. I've since recommended them to friends and family and would absolutely do so again."

"Mike at O'Hara Heating and Cooling is outstanding! He was quick to come out and look at what I was looking to have done. He was professional, courteous, and honest about his recommendation. I have repeatedly hired Mike on many projects including: replacing both the indoor and outdoor AC Condensers after they failed, relocated the condenser line (due to remodel), replaced the thermostat, and replaced the baseboard heating system in my home. All work was completed on time and within budget."

"Landry Mechanical was very responsive to our needs. The boiler installation was very smooth and all aspects of the transaction were positive. They were a little more expensive than some of the other estimates but the quality of our experience was worth it."

"I'm a deep value oriented consumer and this guy is one of the best contractors I've come across for the money. Why would you want to pay for the administrative and marketing costs which comes with the fees charged by the big box guys. D-Day is a true professional and a master craftsman at his work. I've hired him to replace a water heater, install a dishwasher and washing machine, as well as miscellaneous plumbing repairs with exemplary results. I wouldn't even consider looking elsewhere."
