"They showed up one day earlier than the original appoint whic was great! The technician wore the N95 mask I provided. Work was done quickly and thanks to them I was only out of air conditioning for 24 hours. Very happy. Price was reasonable and I set up a maintenance schedule with them."

"Called J&J after our first service person flaked. Wish I had called them first. Howard B was very professional and explained what our issue was in terms we would understand. From first call to completion was about an hour and a half. Super quick! Even on a Sunday, their pricing was more than reasonable! Will definitely continue to use them!"
