Here’s What Others Are Saying About Us

Evan Gaines professionalism and cooperative manner carried the day during his inspection effort. Highly knowledgeable and willing to educate as he debriefed his work, he made the overall plumbing inspection highly palatable. Kudos to Mauzy for housing a superb staff!

5

Jake was polite and nice. He worked in pouring rain and got it done quickly. I appreciate his worth ethic and the fact that it was running well before he left. I would definitely recommend Mauzy to others

5

Robert was polite, answered my questions. He went over some options for repairs.

This Five Star review is only for Mauzy technician, Nathan Benge, who did the diagnostic on my Lenox combo system of heat pump and gas furnace on December 30, 2025.

I had a combo system of a heat pump and a furnace, Signature Collection, which were installed last year by Mauzy. For those of you don’t know much about Lennox models, Signature Collection is the top-of-the-line of the Lennox brand and yes, they are expensive and did have few issues right after the installation!

Last cold Sunday morning, 12/28/2025, my Lennox thermostat S40 stopped working. There was no power to the unit! I contacted Mauzy on Monday and got an appointment with a technician named Nathan Benge on Tuesday morning to visit my home and to diagnose the problem. I’d like to mention the following positive notes from the time the Nathan on the way to my home to the time the he finished the job:

1/ It’s very helpful to me receiving the status update when the Nathan was on the way and tracking information (including the estimate time of the arrival) of Nathan’s vehicle.

2/ After listening to me about the past and current problems of the installed Lenox unit, Nathan verified no power to the Lenox thermostat S40. He, then, went up into the attic of my home, unplugged the unit main power cord from the outlet, and started checking on the connection of the electrical wires inside the unit. He found one of the wires being loosen from the undersized winged wire connectors (past workmanship?). Nathan reconnected the wires with a larger size winged wire connector (see the attached photo with red arrows) and plugged the unit main power cord back to the outlet. The unit was powered on and the thermostat S-40 was also back on!

3/ At my request, Nathan also did the following works:

(a) Re-checked the internal wiring to the circuit board in the blower unit (there were 4 exposed stripped copper wires at the connection to the board). He confirmed they’re O.K.

(b) Did a visual check on the flame in the furnace.

(c) Found a temporary solution to reduce the vibration noise from the heat pump by using the electrical wire jacket to separate the plastic component from the metal frame of the heat pump (see the attached photo with red circles).

(d) Researched and explained the message “Ambient Lockout”, which showed under the “Status” tab of the Lennox app. He explained how the heat pump and the furnace operate when the “Ambient Lockout” message showing up in the app. Noted that I had asked the same questions to previous 5 Mauzy technicians, managers, local Lennox sale representative, and calling Lennox Customer Support. No one was able to answer or explain to me the meaning of the message “Ambient Lockout”! Even worse, all I got back from Lennox Customer Support were two case numbers and no follow-up from Lennox Technical Support. I was also told last March (2025) that Lennox Technician covering southern California region (from Bakersfield to the border) would visit my home, checked out the installed unit, and addressed some of the issues that I had with this top-of-the-line Signature Collection unit, but they’ve never came!

In conclusion, Nathan Benge did a great job!

Joshua from Mauzy Plumbing came in to fix our plumbing issue. He was very detailed explaining the repair and cost associated with repairs. He did an excellent job with fixing the issue and checking everything and cleaning after him self. I really appreciated his professionalism and attention to detail. Although the service is not cheap, knowing that everything is done properly is very comforting. I would recommend him and his services to anyone who is looking for reliable plumbing experience.

I had a new heater system installed in my house about two weeks ago And since that time I was experiencing A noise that sounded like a bass Or subwoofer playing. It happened every time the heater came on. A technician came out and his name was Mr. William Carter. I have to commend him on his knowledge of the heater systems because he knew exactly what I was talking about. He called it a “Whoomp whoomp“ sound. And I replied, “Yes, that’s exactly what it sounds like“. He ran some tests, Made some adjustments with the gas flow, Explained to me exactly what was going on, Corrected the issue and ran more test until the “Whoomp whoomp“ Sound no longer came on. I cannot explain how thankful I am for the time that he took to explain everything to me. He provided great customer service because he showed me he cared by displaying patience with my questions. He went above and beyond by explaining to me how the thermostat worked and I am so grateful he was the one that came To fix the issue. Thank you, Mr. William Carter.

Great service.

Just had Evan G from Mauzy do an evaluation on the plumbing on my home. The evaluation could not have been more complete.
Every bit of the plumbing was checked. Yes everything was good to go but if there was an issue Evan with his knowledge would not have missed a thing. At least 2 hours to go through all the plumbing. I recommend every home owner to get the same service. It will save on the long run and if there are minor issues you will be made aware. Evan G was terrific.

5

Kory was great and very thorough , thank you

Mouzy is hands above any other plumbing/electrical A/C, firm I’ve used in the past, and since I am 80 years old, I’ve used a heck of a lot of them. They are fair, polite, and knowledgeable. I have no idea what More can think of to describe them.

Joshua was professional and courteous. His detailed description of filtration systems, along with inspection and recommendations for correction of my failed in line water filter were a sell point for the filter I subsequently purchased from Mauzy plumbing. He provided above and beyond service, tightening fixtures and replacing piping and components at no extra charge. He demonstrated how water quality reflected filter performance, which turned out to be what he predicted it would. I was more than satisfied with Joshua’s informed and thorough

I should’ve called Mauzy first! Prior to the call to Mauzy I had 2 companies come out to help me with a plumbing issue I had. Let’s just say it got worse rather than better. Finally, Wilber, an exceptional young man to say the least, came to the rescue! Knowledgeable, efficient, and walked me through every step of the process. Pinpointed the problem and had my plumbing issue resolved. Thank you Mauzy for having exceptional employees that know what they are doing! Will continue my services with Mauzy.
