"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."

"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."

"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."
