"Affordable HVAC repair service. You can actually ask them to do little extras at no additional cost. After I called them for emergency repair of our AC unit, they offered a complementary cleaning for the unit. Amazing customer appreciation. Totally recommended!"

"I was very happy with my service call today! The repairman, Scott, was knowledgeable and pleasant and wore a mask and gloves throughout., so I felt safe, despite the pandemic. He serviced both of my central air systems and diagnosed the problem with the malfunctioning one and fixed it. By the time he left my house was already a much more pleasant place to be!"

From the initial scheduling to the completion of the job, every interaction was seamless and courteous. They, arrived promptly, diagnosed the issue quickly, and provided a clear explanation of the necessary repairs. Their work was efficient, neat, and of the highest quality. What stood out most was their dedication to ensuring I understood every step of the process and was completely satisfied with the outcome. Their attention to detail, respect for my property, and willingness to answer questions were truly appreciated. I highly recommend Aqua Tech Plumbing for any plumbing needs.

"Included in the price of the 50 gallon water heater I needed was the plumbers picking up the new water heater, transporting it to my home, navigating the steps down to the basement, and taking away the old water heater. All for the price on the receipt for the new water heater. What Mr. Simpson charges for is the installation of the new water heater and the peace of mind that comes with having a master plumber do a masterful job. Articulate, polite, and efficient, he made me aware of everything he was doing every step of the way. He is obviously a person who takes pride in his work. Mr. Simpson's work comes with a guarantee to amend any problem that arises. A guarantee I have not needed to avail myself of, but appreciate nonetheless. I am thoroughly satisfied with the job he did, and recommend him as an honest tradesman."
