First time I have used AC by J. My only regret is that I didn't know about them sooner. I called in the morning and by mid-day the Tech was onsite. One hour later my AC was up and running again which in 110 degree heat that meant a lot! The tech was knowledgeable, friendly, clean and professional. Thank you AC by J for doing what you said, when you said without all the up-charging that so many companies do. I don't wish for more repairs but should I need something, AC by J will get the call. Thanks
