"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."

"Mike responded to my request immediately, set up an appointment to look at my job and give an estimate right away, and then completed the work in 4 days. Within 8 days of my call my new water heater was installed. The contract was clearly set out, and the work was very professionally completed exactly as per the bid. Mike was very friendly and easy to work with. He left the work area clean when he left. I highly recommend Mike and Jax Mechanical."

"We had a hot spot on the floor and a high gas bill last month leading us to suspect a slab leak. We called several plumbing services and Personal Plumbing was able to come out the next day with their own slab leak tech. The techs were on time and took about three hours to find the leak and reroute and place pipe to repair. They were able to avoid more holes in the drywall by placing the pipe on the exterior garage side, extending us savings. They also showed great integrity by letting us know that any repair would also have to replace factory pressure valve that was no longer working (putting pressure on our system). We will definitely keep them in mind for any other plumbing work we need done!"

"We were impressed with Jason’s presentation of the Mitsubishi system, and we really appreciated learning about the HERO program from him. We got a good estimate,ate for the work but were planning to do our roof repair first with adding solar and thought we would do this job after. Things worked out with that Jason got our work scheduled and done BEFORE the roof/solar which worked out because in Sept/Oct we still had some hot days, Thie crew was professional and extremely hard working, and poor guys, in hot weather, sweating in our attic/crawl space. Which they left with improvements! The system was up and running (2 downstairs units, 4 upstairs) in 6 working days. After a week we did have a problem, nothing worked and they came out promptly to troubleshoot, ordered new circuit board and installed as soon as it arrived. Been running fine since then, and this is also heating so I am looking forward to heating with solar instead of gas."

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.

With the cleanouts snaked, and the blockage located, we can send the hydro jet through the sewer vent and flush out the blocked drain.

"Excellent service! We scheduled Plumbing Plus to replace the hot and cold cartridge's in a sink faucet and a tub pop-up drain and overflow gasket. Jared N. quickly assessed the problems. The faucet was so corroded with water deposits that it could not be dismantled to simply replace the hot and cold cartridge's. So Jared replaced the entire faucet with a high quality replacement. After the tub pop-up drain was replaced, Jared checked for leaks by looking in a 'trap door' in the ceiling below the tub that was left after the tub was replaced in an earlier remodel. Jared discovered that the entire tub drain was leaking and need to be replaced, which he did. He also corrected a problem with the drain pipe left from the previous remodel. Although the job was much more complex than expected, Jared was professional, efficient, and extremely cheerful throughout . We highly recommend Jared and Plumbing Plus"

"I contacted Anderson Plumbing Heating & Air, a honest and trustworthy company after I realized at the last minute I needed a refrigerator water line assessment and they quickly sent Miguel to my home who noticed upon assessment inspection the water pressure was unsatisfactory and recommended replacing the water pressure valve in addition to the refrigerator water line. Miguel was absolutely amazing , a breath of fresh air, very easy to work with, and managed to accommodate my water line hookup needs fitting me into his busy schedule. Miguel provided me with a great service experience at very reasonable price! He went above and beyond providing before and after pictures of my old and new water setup, answers all of my questions, all while providing outstanding customer service with a smile & 10/10 quality of work! Thank you Miguel for a great refrigerator water line hook up experience !!"
