"We had a problem with our water heater only heating half the tank. I called Precision Today and they could not have been nicer. This includes from the time I called, speaking to the woman on the phone. They sent someone out the same day. TJ was incredibly knowledgeable and professional. Turns out we needed a new water heater. He got the new one and installed it same day. This guy knows his business!! I canâ t say enough about the honest, professional work we received. Weâ ve used other companies that didnâ t come close to Precision. So grateful, thank you!"

"The crew was on time (slightly ahead of schedule), through in their work, professional, cleaned up before/after, and highly responsive. Scheduling was done through text, as was the pre-consultation. Further, PorterHouse was price competitive, and offered me one of the better quotes/prices for a water heater replacement."

"Leon was amazing! We had another company out a few days prior to look at our backed up drain pipe. When they arrived, they told us that the c/o pipe had to be installed outside of the house in order for them to rout and flush. They said our crawl space where the inside c/o pipe was, was not accessible, basically leaving us with no other option than a $4,700 estimate to install the c/o pipe. We wanted a second opinion. That’s when we called Top Tech. Leon arrived the next day and immediately recommended to rout out from the inside (even though the first company said this was not possible) first while using a camera to ensure there was no break in the sewer line. Even though a c/o pipe on the outside would be something beneficial in the future, we had just bought the house and were in no position to spend a lot of money. Leon and his crew came two days later and were fantastic! Not only did they clean out all the tree roots that were causing the problem, Leon was great enough to allow me to see the camera as it was going down- to ensure to myself that there was indeed no break. I felt like the previous company was trying to get a bigger job out of me, whereas Leon and Top Tech really has my best interests in mind- not just spending my money. And guess what!? It worked! He also gave me some great recommendations on things that can help with the root growth in the future. And hey, when we’re ready to get that outside c/o pipe installed- I know who I’m calling!"

"In general J&S Plumbing is very responsive, they went out of their way to install a new water heater for us, in a tight space, within just a couple days of my first call. As for plumbing services, they mentioned that they do not charge extra for work in the evenings or on weekends, which many other companies do. The first power-vented water heater they put in had an issue with condensation drip-back, which caused the burner to have intermittent problems keeping the pilot light going. J&S was very professional and responsive to the problem. A month after the initial install, they ended up replacing with another brand new water heater, quickly and at no cost to us."

"Four Seasons arrived earlier than window time and came out to perform the yearly maintenance on my furnace. He said Four Seasons was offering a discount for cleaning the water heater. Since I've only lived here five years and had no idea when it was last cleaned, I also had him clean out water heater. He did an excellent job on both, replaced my furnace filter, and left the area cleaned. He explained everything he did, answered all my questions and said my water heater was very dirty and should now run more efficient."
