Client Testimonials

2022: After having several other companies come out and mess up my duct work KE Greene came out and fixed it right the first time. I found them to be very responsive.Thanks Again! – Stephanie2019: Mr. Greene was quick to respond to my request for replacing my Rinnai tankless hot water heater that bit the dust due to a lightning strike. Our homeowners insurance was not quick to resolve our issues but as soon as they gave Mr. Greene and his team the green light they were phenomenal and quick at accomplishing the replacement. We are so blessed and thankful to have utilized K.E. Greene Mechanical and look forward to our future interactions!

2017: Incredible service was provided when my Rinnai tankless water heater needed serviced! Very knowledgeable and the price was more than reasonable! They arrived when expected! I highly recommend K. E. Greene Mechanical!-Ryan

2022: We have been using Kenny Greene’s services for over 10+years. Always exceeds our expectations with his service, always returns our calls promptly, shows up on time and most importantly he is honest and treats you fairly; he won’t give you the run around or any slick used car salesman tricks. Can’t recommend him enough. Don’t hesitate. You won’t regret it! -San

2023:Recently, we were forced to endure a frustrating dilemma in the form of a badly leaking (50 gallon) A.O. Smith hot water tank at our home. And, left with no option except to contact several different plumbers throughout the Metro Atlanta-Cobb County region and companies that sell gas water tanks, Manny was instead able to prove to the manufacturing company-brand (A.O. Smith) who agreed the model/unit at our residence was apparently defective (since it had only been installed since 2018) and they agreed to provide us with a brand new 50 gallon replacement unit at no cost. 

That gesture…a U.S.-based company that still stands behind their word and lives up to exactly what customers expect of their product(s)…went a long way with us. However, upon making contact with your company to do the installation, we were equally pleased that we chose K.E. Greene Mechanical/Hydronics. Especially since your installation costs were/are more economical than ALL of your competitors and your employees are certified at specifically installing “A.O. Smith models,” which was very important to us.    

From the very first telephone conversation, Ms. Kennedy Coleman, your Dispatcher/Customer Service Rep., was truly professional and courteous! She definitely paid attention to what Manny conveyed to her and she was more than helpful. According to Manny, she simplified the process and promptly arranged for one of your plumbers – Mr. Jacob Meeks – to come out and install the unit today, Wednesday, February 8, 2023. And man, did that young man take his time and do an amazing job! He has a bright future!

Jacob Meeks thoroughly impressed Manny by his immense knowledge of his vocational trade and his pleasant personality. In fact, it is those traits, which both Kennedy and Jacob clearly have mastered quite well, that will compel us to encourage countless other people in our neighborhood (Kensington Community subdivision of Smyrna) to consider K.E. Greene Mechanical/Hydronics as potentially new customers going forward for similar work that involves plumbing, HVAC, and/or electrical type of work.  

Delivering ideal customer service to customers and consumers continues to be a serious deficiency for most companies and organizations across all sectors of business throughout the U.S.” Thankfully, individuals like Mr. Meeks and Ms. Coleman, possess phenomenal customer service skills and a likeable, down-to-earth personality that motivates weary consumers-customers like us to remember such positive encounters and recommend K.E. Greene Mechanical/Hydronics to other people. 

In closing, I also hope my words will enable Mr. Jacob Meeks and Ms. Kennedy Coleman to be recognized and honored for their outstanding customer service skill set and ability to problem solve. What they did was rare, yet appreciated. Often undervalued by both a company and a customer, but genuinely appreciated by us. -Brenda
