What Our Customers Say

90 degrees on a holiday weekend – of course the AC unit is going to fail. The next week is going to be 90++ every day. Luckily for my family J&J saved the day! All of the representatives and technicians were professional, considerate and thorough. Owner called back in minutes after leaving a message on Labor Day. Technician was at my front door within the hour, confirmed the bad news – new unit was necessary- and headed back to the shop to bring us multiple portable AC units to get us through until the next day when they were there at 8:30am promptly to install my new unit. Couldn’t have asked for more but the price was great too! Thanks J&J!
