"Adam is by far the best plumber I’ve had do work in my home. We have done a number of remodeling and repairs throughout the year and he’s the best. Here’s why: very knowledgeable about plumbing issues; found the best solutions for our project and he studied the best way to install and did excellent work. We had a Halo 5 water softener and filter system and on demand hot water recirculating system installed. We now have great tasting water out of the tap, no more greasy feel in the shower and no more waiting for hot water and waste of water waiting for it to get hot. Both systems work great."

"This was our first experience using Wighton’s and it won’t be the last. Aaron was very professional and very nice to work with. Our air conditioner stopped working and he was able to fix it and did some maintenance work on the unit also. He also pointed out that we needed to replace the air filter which services our hvac system, which we were grateful that he did because we had never had it changed out with a new one and it was long overdue. We signed up for their maintenance program so that our ac/heating will be inspected and maintained on a regular basis. We are very happy with his work and highly recommend Wighton’s!"

"He was great--very professional. Picked up the items from Sears at no charge then installed them at a very reasonable price. At the same time drained my water heater for no change. A year or so later returned to fix a leaking pipe and again drained the water heater for no charge. I would hire him again without hesitation."

"We contacted them one day and thought we were not going to hear back but when they returned our call, they came over the same day.  He quickly diagnosed and repaired the problems and was very nice to work with.  Additionally, his prices were amazing.  We will definitely be calling on him again."

"I recently had Central City Plumbing install a new water heater, and I couldn't be happier with their service! The team was incredibly professional and efficient, completing the installation quickly and without any hassle. They were also very friendly and took the time to explain everything to me. The whole process was smooth, and the quality of their work is top-notch. I highly recommend Central City Plumbing for anyone in need of plumbing services!"
