Electrical Repairs in San Diego County

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

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!

Carter is very knowledgeable, he is certainly an asset when it comes to customer service!

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.

Robert was wonderful ! He is so very trustworthy. He calmly explained what was wrong and all the options open to me. He didn’t hard sell anything but worked with me. He is very neat. When he was finished he patiently explained what he did and how the system worked.

Did a great job cleaning the drain of my bathtub. Abraham was very nice and took care of everything and explained everything very well. A good service to use in the future.

Working with Mauzy has been a breeze. Had some issues with our system and they sent a technician out as soon as they could. Wound up working with Mr. William Carter who was very knowledgeable and did a fantastic job. I couldn’t be more pleased with the service he provided.

Christian rewired furnace and enabled my new thermostat to work perfectly. Great customer service.

Your service representative was very polite and professional while dealing with me. Thank you for good servjce.

Informative and detailed analysis of our HVAC system by technician Mike Mitman

Christain was amazing. Efficient and honest.

Excellent service. Joe answered all our questions and he was professional and knowledgeable.

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.

I highly recommend Mike Ward at Mauzy! Mike took time out of his busy schedule to assist us with a clogged drain. He was very friendly, efficient, knowledgeable and even cleaned up after himself. We will definitely call on Mike at Mauzy again for any and all heating, plumbing and electrical needs!

Christian was awesome. Professional, knowledgeable, technically skilled, he did a great job.

Jushua was the best!!so knowledgeable and friendly .. an asset to your company!!!

Was provided amazing and excellent customer service. Was notified of anything that needed to be cleaned or maintained.Kylin Was very professional

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.

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.
You’ll be happy with them!

James Logsdon was our Tech. He is very professional and lets you know what he will be doing. He kept me informed of everything. He was amazing and I trust him. Best Tech ever.

Darren was very through in completing the service maintenance for my heating system. He took numerous photos and explained everything in detail. Thank You Darren!

Brandon was our technician, and was great about communicating prior to his arrival with an estimated time to be at our home. He was very pleasant, and explained what services he would be providing. During his visit, he was respectful of our property and kept us informed on progress of the work provided. He left things in order and provided a final update on his analysis of our plumbing. Very impressive service.

James is an excellent technician! He sourced the problem and handled the follow up in a professional manner. He clearly explained the issues with our heater. We appreciate his knowledge and courtesy!!! Our heater still under warranty for the part that had failed so no payment was due at this time.

Joe Annello was extremely thorough and explained his findings and answered all my questions. He was very professional and on time.

Both Darren and Joshua were kind?respectful, informative and gave many options to choose from!

Christian is knowledgeable of the job and very professional

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
service. Thank you.

Kory was professional, proactive, courteous, and answered all of our questions regarding heating and air conditioning maintenance.

Prompt and well informed. Thank you.

Excellent service. Was able to get same day service. The technician, Kory went above and beyond to get my heater repaired in a timely manner. He was very personable and took the time to explain the details of the problem and the repair.

Got great service today from Evan G. Yearly inspection on our water heater and routine check on pluming in the house. Fast reliable service and recommendations on future and preventive maintenance. Thank you Evan and Mauzy for great service.

Kory was very professional and answered all our questions.

Excellent service!

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.

Tommy and Alex were totally awesome.

Technician Michael Mitman was very professional and helpful. More importantly, he got the job done in an expeditious manner.

Mauzy was very professional and did a great job. Especially appreciated Chris and Alejandro’s work.

On Time, very friendly and efficient. James is very easy to deal with

Thanks Robert for your great service.

Just got my new furnace installed. My technicians Chris and Alejandro were quick with removing the old one and installing the new one. Both were very helpful to help me with my thermostats and explain every part of the process with the new furnace. Im completely satisfied with their service.

James was very knowledgeable. He fixed the issue 3 others couldn’t

I highly recommend Mauzy! Their technician Wilber did an amazing job! He was professional from the moment he arrived. He was respectful, knowledgeable and very thorough. He quickly identified the issue and took the time to explain my options clearly. He made sure everything was cleaned up and working perfectly before leaving which made the whole process smooth and stress-free. Definitely recommend this company and highly suggest you request Wilber!
