"Did a $59 consult only. Turned out the cost of repairing the old heater was almost as much as a new one, so we got a new one, and handled the install ourselves. Luis B was great, knowledgeable, friendly, didn't try to upcharge just to sell a heater, which we appreciated. Gave us an honest evaluation, several options, and was right on time. I will say, though, that the company failed to call me when he was on his way... not a big deal. All in all a good experience."

"Unbelievable customer service. I’ve needed a new water heater for a while, been calling around for quotes. And this was the best!! They came out within a day and took out the old water heater and installed the new one within a few hours. Their customer service was top notch, their install was great and their clean up was very thorough and best of all was the price!"

"Overall great experience. Donald, the inspector, arrived early and patiently waited with me for my real estate agent to arrive. Donald did a thorough inspection of the inside and outside units. He was very knowledgable about pertinent laws and regulations and took his time to explain them. He also explained that the HVAC unit is old, but functioning and that it may have to be replaced in a couple of years. When that day comes I will definitely call Carini again, and ask for Donald."

Hydro jet uses water at 4,000psi to clean the inside of the mainline drain which connects all the home's drains to the city's sewer system.
Using a snake we can go through the cleanouts on the side of the house.
With the cleanouts snaked, and the blockage located, we can send the hydro jet through the sewer vent and flush out the blocked drain.

"Your guys CJ & Andrew were awesome! They did such a nice clean looking job! Super professional and very informative. They walked me through setting up the app for the whole house water shut off valve they installed and now I get a reduced rate on my homeowners insurance. They also found that my water pressure reducing valve had failed and replaced that at the same time. Couldn’t be more happy with the job they did."

"Tarpy was recommended to me by an electrical contractor I trust. Scott spent the time needed to go over all options for repairing or replacing my old system. I decided to go with a full replacement, and to install new mini-split systems throughout the house. Bowen did a great job working through some tough challenges to work the cleanest install possible. We needed to make a few changes to the install plan along the way and, to his credit, the owner, Broc, stepped up and worked out a fair way to get the job done and done right. Jessica was patient and thorough with the followup paperwork. All in all, a great team, I highly recommend Tarpy, they're an honorable team that delivers on what they promise to do."

"Eddie at Steady Plumbing is a conscientious and friendly professional. He did a great job installing our tankless water heater in a tight, tricky space. Added to that, he knocked out some plumbing issues that happened to pop up during that job, including a blocked drain line and wax seal replacement. Great work—thanks Eddie!"
