"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."

"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.

"Quick response, worked with my schedule to review the project and 24 hours later it was done. Manny took his time to explain options, his crew ran into a snag, solved it and the results are great. This quality of service is so rare that you might expect prices to be higher. MHG is professional service at a reasonable price and really great work. I highly recommend MHG Plumbing!"

"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 !!"
