"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!"

"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."

"Javid was great. He came the same day I called, explained what he was doing and got it done quickly. I've actually used him three time: New water heater and two plumbing problems. I hope I never have another problem, but if I do he's the one I'll call."

"The owner was pleasant and came on thanksgiving week-end but charged $129 to solely inspect the furnace. His estimate for repairs was way higher than another company that we went with and fixed the problem."

"We contacted several water filtration companies in the area and we were disappointed with the lack of response to our questions about a complete home filtration system verses an RO system. When we contacted water fixers Lynda was very knowledgeable and responsive to our questions and sent information to us in detail to our email address for us to review and make our decision. Once we made our decision and signed the contract we scheduled an appointment. They were prompt and efficient in there work. Victor and Mike installed the system and asked question about placement of the system allowing maximum use of our under sink space. The install was done quickly and efficiently because of the experience and attention to detail of the technicians. We are working with them now on a hot water circulation system to prevent wasting water while waiting for hot water to reach the fixtures. They also provide service to systems they install and any other plumbing needs we or you may have."
