Steve SachtlebenTrustindex verifies that the original source of the review is Google. Carlos arrived promptly and finished the job quickly. I was at my office and my wife was home alone, but Carlos was very courteous and polite. A good job done very professionally. John RyanTrustindex verifies that the original source of the review is Google. J & J Mechanical was sent out to service my a/c through Landmark Home Warranty. Carlos arrived and diagnosed a refrigerant leak in my upstairs unit. He added sealant and charged the refrigerant level back up. Total cost was $195.00. Carlos took the time to explain everything to me in detail and even explained the next steps if the sealant fails. A previous company through Landmark Home Warranty immediately escalated the repairs to a total replacement with an out of pocket cost of $6,800.00. That company ended up going out of business. All in all, I am very pleased with the service from J & J Mechanical and would not hesitate to contact them again for any a/c or heating issues. Thank you again for your honesty, great communication and great service. McCalle FryarTrustindex verifies that the original source of the review is Google. They took care of me from the very beginning. Very nice and always here when they said they would be. Would definitely recommend and will now use them in the future. Batgirl OnAHarleyTrustindex verifies that the original source of the review is Google. Extremely nice, professional, accommodating business. We had an A/C failure and contacted our warranty company, American Home Shield. The ONLY problem we had during this event was with the warranty company. It took AHS almost a week just to find us a provider. Once J & J was contracted Janie scheduled her technician Gabe and he was at our home the next day. Gabe quickly diagnosed the issue and recommended replacing the unit. The American Home Shield rep told me they had 5 or 6 different brands available, but when AHS put me on a three-way call with AHS and J&J, Janie corrected the AHS rep and informed her the only brand they were authorized to use was Goodman. The AHS rep agreed with Janie (weird, cuz that’s not what she told me literally 2 minutes earlier). I’m extremely disappointed with American Home Shield (they are definitely not what they used to be) and I’m sad for J&J because AHS essentially clipped their wings by only allowing them to offer a substandard unit. Janie at J&J is so very sweet and professional, Gabe is friendly, knowledgeable and honest. I wish we could’ve done business. Jennifer SmithTrustindex verifies that the original source of the review is Google. J&J Mechanical were dispatched through our warranty company after our thermostat went out. They accepted and provided a date and time for the next day. Carlos came out and located the source of the problem and got the issue taken care of quickly. Great job! Eran VaizelTrustindex verifies that the original source of the review is Google. Their technician was here yesterday for an intermittently not cooling AC. Did something, didn't work, AC is not cooling intermittently again today. Tried calling them and I ran into the stupidest and most bizzare conversation I've ever had in my life with their dispatcher. They claim they cannot fix the issue because "the AC is working when they're here", so there's nothing to fix. Yep, you heard it right. If the AC is only intermittently not working, they can't do anything because it's fine when they're here. I asked them - how about digging deeper into the issue? They couldn't understand what I was talking about. Very low level of service, knowledge and professionalism. Don't waste your time with them. Edit: The business has responded to my review here, wondering why I called them back if they're so bad. Well, I didn't have any choice - my home warranty forces me to work with the same vendor until full resolution, even if they're crappy. Kristen DaigleTrustindex verifies that the original source of the review is Google. Carlos was amazing. Very kind and professional. Answered any questions we had and called before he came. The staff went above and beyond on working with us and our insurance. It's rough having no AC in the middle of summer in Texas but they made the process smooth. 10/10 Ramiro RodriguezTrustindex verifies that the original source of the review is Google. The team was very helpful and worked with me to replace my two home AC units. They did a great job and priced the units and installation at a very competitive price. They were the best priced solution from four bidders. They understood what I needed and gave me a good solution within my target budget. mildred AkinyiTrustindex verifies that the original source of the review is Google. They sent a technician, who claimed my AC unit had partsossing,i was in hospital bed face timing with hubby when I asked him to show what parts were missing and he suddenly did not speak English again.
