They converted my furnace and water heater from propane to natural gas and they were responsive, professional, and patient with me as new homeowner. I’d recommend them to anyone!

J&J placed a whole house generator yesterday. I’ve used them a few times before for small tasks, and have always heard good things about them so when we decided to take the plunge I knew who to call. They were pleasant and courteous from the office staff, to John at my consultation to the work crew lead by Hunter and the Electricians that were brought in to do the work. They all did a great job, kept us in the loop through out the day and cleaned up when done. I would definitely recommend them.

I had issues with my oil furnace & John & Evan were able to fix the issue. They were great. I highly recommend this company.
