"Removed old water heater and installed tankless. Explained what needed to be done. There was some misunderstanding on what was needed that I said I would accomplish prior to their arrival. They stuck to their estimate even though they had to do additional work."

"Amanda Plumbing is absolutely AMAZING!!!! I had them out over the weekend for a leak that was going into my ceiling. It turns out that it was from our upstairs bathroom toilet (which we were going to replace anyways) The plumber Tyler was super kind and helpful. He fixed our leak and installed the new toilet that I had on my hubby's to do list. I was also surprised about how reasonable their weekend rates were and how fast Tyler got out to us. Thank you again. We will defiantly be calling you back when we have a tankless water heater put in!!!"

"This company was very responsive and professional. I called needing an emergency installation of an electrical line and box for a gas cooktop so that the cooktop could be connected. This was on a Tuesday evening and the line and box were installed the next morning. Matt Wehrie called to confirm the time of arrival that morning which was met. The charges for this service were quite reasonable. The installers were pleasant and professional. I would use this company any time that I have need of an electrician.

"Impressed is an understatement! I called Apex when my mom's water heater went out and the company her home warranty sent couldn't repair the shut off valve. They came within 1.5 hours of me calling and were amazing. They repaired the shut off valve and took the time to explain everything. We were so impressed we had them install the new hot water tank instead of using the home warranty company. Charles was able to do everything the same day and worked around the water mitigation company. He was so professional and did a great job. We will definitely be using them for all our future plumbing needs!"

"Apex Plumbing, Heating and Air Pros, are the place to go. They come out and give you a free estimate and honest opinion. I had them replace my water heater and my furnace, and they did a wonderful job on both. I felt that I got the best deal and I was not taken advantage of because I am a woman. I fully recommend Apex and would not go with anyone else"
