I had an urgent need for a non-cooling a/c and JMM responded rapidly, allowing me to get back to my hospitalized spouse quickly. I have tried others. but JMM has my business for life after this experience !! It is rare to find a business that practices true customer service and delivers quality work. Outstanding company!"

— Harley Hoad · Dec 18, 2025 · Google Reviews"James is great. He has worked on our system several times and never over charges. When they were chasing a slow coolent leak (in the heat of August) he would call and check in on us. He managed to patch the copper supply lines instead of replacing them."
— Julie L · Jul 14, 2025 · Google Reviews"It’s great to find a company that can charge whatever it wants, but stays ethical and gives customers great service with affordable pricing. James did a great job. He showed up the day I called, figured out the issue, said he’d return the next day with the part, and that was it. Fast, friendly, and economical, that is what makes a great businesses and experience."
