"Andy diagnosed the issue quickly and solved it."

"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."

"Had maintenance done for heat pump & mini splits. Rafael Guzman is was professional and knowledgeable . He explained everything he was doing clearly and gave pointers to maintain system. Would definitely recommend N.E.T.R / Sila"

"This mobile user did not provide any additional comments."

"I had James in my home to install light fixtures in my hall, dining room, and bathrooms, he also installed recess lighting and new electrical switches in the basement. He was very responsive to my calls, he was professional, very conscientious an thoughtful about his work, throughly clean up after the job was completed. I would highly recommend him!"

"Daniel worked with me and my schedule, to replace an outlet. He was nice and knowledgeable and priced accordingly. I would hire him again"

"My job was fairly complex, which is why I went directly to Heritage - I wanted to retrofit a trailer with a forced hot water heating system (replacing a hot air furnace). It required a finding a boiler from one specific manufacturer, adding the hot water baseboards throughout the trailer, and dealing with installing pipes in an uninsulated crawl space. Tyler, Mike and Dan were professional, courteous, did what they said they were going to do, explained all the new features, left the house spotless. All are very knowledgeable and skilled in their profession. I have never been anything but delighted with the quality of work performed by Heritage employees."

"Work completed as promised"

"Scott did a fantastic job. Inducer motor was not working in my carrier infinity furnace. He fixed it without me needing to replace the expensive motor. He is good in communication and explained my questions patiently and effectively."

"Everything went smoothly. Even from the first time contacting them, they were always very responsive to all of my inquiries and helping me select the best ac and heating system. The team arrived on time from day 1 onwards and did everything to get the job done. They kept me up to date on the progress as well through out the installation. On the last day they showed me all the equipment they installed as well as how to run the thermostats they installed as well. We had a slight problem after about a week with one of the wires running the fan, but Keith (the owner) came out within 12 hours and fixed it. Everything now works as planned and we are very satisfied with it! I would definitely recommend them for anything for your heating and cooling needs."

"Eric was very responsive, quick and knowledgeable and most importantly had extremely great competitive prices! Will be a long time customer!"

"Carmen fixed the electrical wiring system to my in-ground pool pump. I was so thankful that he was willing to complete the job the day after I called in order for me to get my pool up and running before the heat wave. Carmen did a great job correcting the wiring system that had been installed by the previous home owner. Carmen was professional, worked efficiently, and most importantly made the house and pool safe for me and my family."

"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."

"Technicians were professional and efficient. The technician was very pleasant and respectful. There was a slight issue, not the technician's fault, but they responded quickly to my concern and returned promptly to address it. I would use them again."

"The actual work was well done, the scheduling and timeline were challenges."
