"Neo was excellent! My water heater went and a new one was installed by Neo and his team the next day. They were very professional, communicated instantly, and did a fantastic job. Will definitely use S.S Piping n Heat for all of my future plumbing and heating needs. Would recommend this company to anyone!"

"This was a relatively small water heater repair, and Ryan did an outstanding job. He responded immediately to my request, provided a reasonable quote, was polite, professional, knowledgable, and friendly to deal with. Will definitely hire again if needed."

"They were very fast to respond to my call and were able to send someone within two hours. The replacement of the hot water heater went well. For the water pipes they use copper crimp fittings instead of soldering so it will be interesting to see how that holds up over the years. My only concern is how they ran the gas line. They use Gastite CSST which is fine, but the CSST is run so it goes downward then back up and then downward again before it enters black pipe that has a moisture trap. It seems to me that if there is any moisture it will end up in the CSST instead of the trap. In addition, there is a pretty good bend in the CSST right before it goes into the trap section. Also, Teflon tape was used on the all the joints instead of joint compound. I think I will get someone from a different company to come in and take a look at it."

"Rob had recently replaced my kitchen and bathroom faucets and I called him to see if he could now replace my gas water heater. I was happily surprised when he said he’d be out within a couple of days and I was REALLY pleased with his estimate. For both jobs, Rob showed up when he said would and was both fast and efficient. He’s a great guy - dependable, reasonable, professional and focused on providing good service to his customers. Rob is my “go to” plumber from now on!"

"I initially hired them to fix frozen pipes and a broken water meter. They responded quickly to my call even though it was right after a blizzard. They also diagnosed that I had considerably high pressure, 110 in the house and adjusted that accordingly. I also chose to have them install a small heating system in the space under my house to help reduce problems with future pipe freezes. I have an unusual situation where my house is elevated because I am in a flood zone which makes the lower pipes more prone to freezing. They got the entire system and plumbing work done in a single day and now the underside of my house is much warmer and hopefully this will prevent future pipe freezes and bursts."

"A different company gave us a quote for $500 to clean the condenser and $2500 to recharge it to check for leaks, so we were dragging our feet. I decided to get another opinion and found Comfort Doctor. They were incredibly responsive and came the next morning. They cleaned the unit for $65 and recharged the unit right then and there with 1 lb of refrigerant. Now it is working great for ~$300. The technician gave us recommendations as if it were his own home and said the quick and inexpensive fix is where you should start. We might not need to do the more expensive leak-check at all unless the system continues to leak substantially."

"Zach Brown initially came to fix leaking water situation and then realized there was damage due to water seepage. After that damage is repaired, Zach will return to put plumbing back in order, including replacing faucets which had to be cut out to allow removal of granite countertop, reconnect water lines and possibly reinstall a new Reverse Osmosis system since the old one had to be removed. Can't say enough about Zach -- his professionalism, his explanation of what's being done and options for replacing/improving plumbing under kitchen sink, pipes, etc."

"I had an incredible experience. My water heater was leaking and ready to let go. Brian had contacted me. He set up an appointment the next morning. The two gentleman ( plumbers ) came in. Removed the old water heater. Installed the New water heater. And updated the vent piping because it was old and out of code. They did a wonderful job. And I cannot speak highly enough of them , the speedy work and their professionalism. I now have a new plumber for all my plumbing needs. Thank you."
