"Brayden did an awesome job, he was very friendly and talked me through all my options. My only issue is the job was started way later than the time we were told, but Brayden came out past 7:00 pm and got the job done so respect to him."

"I recently had the pleasure of working with Middle Water LLC for spray foam insulation on a client's home and was thoroughly impressed by their professionalism and quality of work. The team consistently showed up on time and adhered strictly to the bid they provided, showcasing their commitment to reliability and integrity. Their dedication and work ethic, particularly the impressive contributions from the hardworking Amish labor, were remarkable. Based on this experience, I have confidently referred Middle Water LLC to another client, who is now planning to use their services as well. The excellent job they did, combined with their punctuality and adherence to the bid, make them a standout choice for insulation services. I am so satisfied with their work that I intend to use them for my own home, which I plan to build in the near future. Middle Water LLC has earned my highest recommendation for anyone seeking top-notch spray foam insulation for their home or business."

I would highly recommend this company."

"Beware of shipping issues with this company. Ordered an ice maker installation kit on 10/10/25. Shipping was due no later than 10/20 according to company and FedEx tracking. FedEx tracking showed the package at their facility for 8 days without moving beginning on 10/15. Called FedEx 3 times. Each time they said they cannot find package and I have to contact shipper. Shipper has to make a claim, they will not mark it as lost. Called Appliance Parts Pros twice. Each time they say FedEx has to mark package lost before they will do anything. They also state they have to wait 14 days from them before doing anything because of their contract with FedEx. I don't care about their contract, I want what was ordered and paid for. Just going in circles with them and FedEX. If they shipped after 14 days it would be 22 days from that point, 32 days from the date of order if they shipped it that day. There was a deadline for installing this part before tenants arrive. They did not care, would not m"

"Did all I wanted and more, on time, on budget, kind and efficient."

"I knew that I was going to need very good help with this water heater replacement. The old one was 22 years old and had a lot of sediment in it. Also the location was difficult to get to. Jack sheduled the appointment to fit my schedule. Brad and Mickey arrived promptly and tackled the situation. As expected, the drain was clogged and the tank was way too heavy to lift out without draining. When using air pressure failed, they pulled out a shop vac, jerry-rigged a small hose on the end and slowly suck out enough water to allow the tank to be lifted out. They're one of the best crews I've ever had working for me. I have my mechanic, my electrician, and now I have my plumbers. I'll never use anyone else and I highly recommend them."

"We were long-time customers of Knight having been Royal Maintenance Program subscribers for several years with our 14 year old, high efficiency furnace. From time to time they have said we needed repairs, some expensive. We paid the bills thinking the costs were legitimate. At the most recent visit (October 2020) one of their technicians came for a regular maintenance visit and said he had discovered a carbon monoxide leak and had to shut our H/Vac system down for safety reasons. He advised that our furnace was so old (14 years) that tracking down the leak would be very expensive and subsequent repairs would cost nearly as much as a new system. He recommended (several times) that their sales office contact us for a bid on a replacement furnace. I was suspicious and called another respected company in Springfield. After a lengthy inspection they said there was a small, intermittent carbon monoxide detection that seemed to be coming from an exhaust pipe with a comprised seal but they couldn't be certain that the heat exchanger wasn't leaking as well. Since that would require removing and replacing the exchanger they checked with the manufacturer and found that it had a lifetime warranty. This meant we could get a brand new exchanger for the price of the labor to install it. Final result was that it ended up costing us a few hundred dollars instead of many thousands that we would have spent on a new system if we had followed the tech's advice. This experience has made me question every service Knight ever performed for us and in the future we will be doing business elsewhere."
