"In the middle of a heat wave my AC broke down during the night. I called a company I have used previously, but they weren't able to get to me for at least a week. While searching for a repairman using an app Circumvent contacted me and would come that day by 6 pm. The technician was able to come earlier. He found the issues right away and was able to repair my AC in less than an hour. The price was fair. He explained everything to me before proceeding."

"Eric was awesome! Replied to my initial inquiry right away. He fixed my bathroom ceiling fan and replaced some outlets in my bathroom. He checked everything to make sure it was safe. Super friendly and I felt very comfortable. Very reasonable with pricing as well. I would highly recommend Angell Electric! Thank you"

"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."
