    This company is THE ABSOLUTE BEST. Absolutley outstanding customer service and caring deeply for their customers. Not just seeing us as money but as humans. This company helped us so quick when we were without heat in the cold and had children at home. Every single employee I had interactions with were so professional and caring. They got things done quick and efficiently. They even helped after our contractor dipped and we were left with more things needed. HIGHLY RECOMMEND. Thank you all so much!

    Furnace stopped working. Call and they came out in 30 minutes. Tech was very nice and told me the problem. Got us back up and running in negative weather until the new part comes in. He cleaned our Furnace and explained what happened. Great service

    Dave came by and did a very speedy and courteous job on our sink drain. AT Klemens are our go to company for our house maintenance needs. Thanks so much! DC and Ryan did a very quick job on our kitchen sink cutoff valve replacement. Their assessment was very speedy and the actual work went much faster than I expected. Included a quality tubing replacement for my refrigerator supply line which had failed. Very courteous and professional men that value time and quality. What this customer has come to expect from the AT Klemens family. Thank you so much and God bless these workmen and the trades. Service date August 6 2:15 pm. Our Tech Kai did an outstanding job getting our Air Con back up and running. His superior problem solving and Can Do attitude are very refreshing to witness. A T Klemins as always knows how to pick em. This Customer calls them for virtually all our contractor needs. Service date 2 Aug 2024 2pm.

    These people were great! In order to install my gas stove, pipes had to be put in, electrical outlet changed. Very professional and made sure everything was perfect and I was happy. Special thanks to Tony and Colton (plumbing), and Dave the electrician. Mariann

    Let me start off by saying that each professional I have encountered at AT Klemens starting with Keri at the front office who is a total sweatheart to John giving honest, realistic bids and reseasonble repair times, despite hectic schedules. I would specifically like to highlight one member of your team at AT Klemens, one of whom I know to be such a fantastic mentor and I hope one that is cherished for many years to come, I truly hope my son can learn from a man like Dave someday. Dave came into my home to look at a few plumbing repairs. My husband and I recently bought a home which needed alot of repairs, while the home needs updating in many areas the plumbling repairs were rather minor compared to the updates we've had to tackle so far, but to me these repairs meant the world. Dave looked in the master bathroom and first moved my bathroom rug out of harms way, LOL which he says he makes sure all his apprentices learning from him do the same which I really appreciated and it's stuff like that that means alot to homeowners when you're letting people into rather intimate parts of your home. He is respectful of your space while giving solid advice on repairs for your home. I wasn't expecting to get the work completed that day as Dave was there to give a bid. Not only did Dave fix the horrible leaky sink, he fixed the shower so it's fully functional while we budget and schedule to have the shower replaced. He took it upon himself to just get the job done, not only did he do a fantastic job on the repairs but he used his years of expertise to coach and mentor in the right direction which is needed these days. In the age where AI is taking over most American jobs, Dave is an example of a hard working true American patriot that goes above and beyond on a day to day basis helping out everyday hard working people. His knowledge and years of expertise are so appreciated and he can't begin to know just how much of difference he actually made in our home. So thanks so much D

    While this company could not complete a project for me due to liability reasons, John spent lots of time on the phone with me explaining my options. So impressed with the customer service and willingness to help despite not making a dime off me.

    ATK has been our go to for as long as I can remember.

    Reply from the business

    We are sorry. When you spoke to the dispatcher, she explained that the plumbing department was scheduling a minimum of three weeks out but she would try to fit you in sooner and would call if there was an opening. Obviously there was a misunderstanding. We apologize again .

    I had just bought a house and needed my water heater replaced. John called me back right away. Made an appointment and got my new one installed the next week! Great service, great work and great prices! I will use them again for sure.
