Recommended Customer Reviews

My original review was not positive based on communications. We received a call from our sales person, Dan, who sent pictures of what was in our attic. It matched what was taken out. He also apologized for the interactions we had during the installations.
Yes, I'm pleased with the outcome, but when I reach out to owners of a company, I do not expect to be ignored. At the very least, communication that we will receive follow-up from a member of their staff, which in this case was Dan, would have gone a long way and would have been appreciated.
Communication is extremely important. There are ways to communicate negative information in a positive manner.

This review is specifically for Deon who went above and beyond our expectations! We had Honey's Air and Solar come out to quote us for some projects and literally the day after coming, our Motor blew on our HVAC, terrible coincidence. We called them back out, they diagnosed the issue and then sent a Sales Person to our Home for a New Unit instead of asking if we wanted to repair and scheduling a date. I decided to call DeHart and Deon came out, arrived promptly, diagnosed the issue, gave us the options and pricing of repair vs. replacement. Upon our request, quoted us to replace all of our ducts, seal, remove insulation, replace insulation, new venting system etc. for literally 1/2 of what Honey's was quoting. He even told us about a bunch of rebates through MID and PG&E which saved us over $1000. If I could give more Stars for Deon I would, he was absolutely amazing. I'm only hoping the work and follow-ups exceed our expectations the way that he did. Thank you!

I was out at Tulloch Lake this weekend and encountered a very rude young man driving a DeHart company pickup and towing a trailer. He ran a cyclist off the road and was not very nice. Then the cyclist mentioned the careless driving to an older man also driving a DeHart company vehicle. This older man said he was the dad then started berating the cyclist. His anger, his hostility, his ""choice of words"" caught my attention. As I observed, I decided this is not a business I would recommend. Imagine if they messed up my repair?
Moral of the story, if you are going to be a jerk, don't do it in a company vehicle.
The owner said they do not use trailers. They pickups, with their name clearly printed on the side doors, were towing boats and stuff. So, I stand by my review that this business lacks the integrity I would expect from a contractor.

I had previously posted a negative review about DeHart. After they diagnosed a cracked heat exchanger, another tech and PG&E diagnosed no problem. I was convinced DeHart was trying to scam me. After talking to the manager, getting some pictures and doing some research, I was not so sure anymore. Called the second tech back, he looked more closely and finally found the crack. DeHart was absolutely right with their diagnosis!

Annual hvac service went smoothly. Great technician. Couldn't be happier with their service.

We have newer home with bath fans tapping on windy days, probably need new dampers; Dehart came out charged 89 for diagnostic, then wanted 2100 for 3 bathroom draft stoppers/dampers installs, with new fan installs, that's 700 per fan install when parts are probably under 100, my guess the jobs would take less than 3 hours each, that's 200 per hour labor. That does not seem competitive nor necessarily needed, causing me even more work to find a reasonably priced electician to do the job. Very disappointed.

Our landlord made a service appointment for our Cooling system without us knowing here in Tracy, CA. Glad he did though! We had an amazing experience with Dean! Being extremely polite, knowledgeable, and caring are just a few adjectives I can bring about! Unlike other service companies that have done our yearly maintenance and try to upsell us unnecessary things, Dean recommended only swapping out our filter which we haven't done in about a year. Being absolutely right, I called my landlord and told him to please call DeHart Plumbing Heating & Air for our scheduled maintenance from here on out! Hey boss, please give Dean a shoutout for the A+ service, very well deserved. I will also recommend this company to my family and friends!

I'm beyond grateful for the work done and help given. We had a leak under the sink, which was discovered and fixed, a faucet replaced and the attention to detail and care with which it was done (wearing masks, carefully social distancing) was exceptional. Thank you Rich Davis and Spenser Wery for your quality work and thoughtfulness. But that's not all. I asked, while they were there, if they would look at a couple of other issues. They were happy to oblige. The outdoor faucet pipe (coming from inside the wall) that entirely rotated (360 degrees) when we attempted to turn on the faucet was of concern. We were advised that we'd have to open the wall to see what kind of connection was done inside that allowed it to turn. Rich suggested we do it from inside as sheet rock is easier to ""fix"" than stucco outside. We agreed and scheduled another appointment. In addition, a botched bathroom remodel left us without installation of the handicapped shower hardware. He was asked if he could take care of that for us too. ""Of course!"" But it, too, would require opening up the wall as it turned out that there was not enough wood to securely attach grab bars and hardware. He knew a person who could finish stucco so you'd never know there'd been a hole. Long story short, the outside pipe fitting was changed and secured and so the outside faucet could be used and you would never know there had been a hole in the wall. Next the shower was scheduled. He was willing and able to add wooden supports himself to securely attach the hardware and grab bars. It works beautifully. Now, that bathroom wall too looks like it was never disturbed. Not only that, he knew a man who could fix anything related to tile, who could regrout the shower cracks that had begun to appear and add and replace cracked or damaged tile, and he was also amazing. Rich Davis is our hero. He was caring, competent and went above and beyond so that my severely handicapped daughter can finally begin to learn how to use the handicapped shower hose, and as I get older it will help me, too. After Covid, we may have more work to do, but we are so grateful that de Hart Plumbing has such exceptional people and contacts. From the bottom of our hearts, we thank you! Oh, and my dishwasher was not level, so Rich tightened that up, too while he was at it. Above and beyond. Thanks Rich. We'll never forget. All this with masks and distancing!!!!

Serviced HVAC. On time, friendly knowledgeable service, explained what he did and answered my questions. I've used DeHart for years and will continue using them!

I'm sure this company deserves more than one star in general, but unfortunately they deserved it for my particular service. Be sure you speak to them about cost and what exactly they're providing. My wedding ring went down the toilet. They pulled the toilet, ran a snake through the line inside and called it a day. We paid $450 for this. We then called the City of Modesto, who responded in under an hour ran a camera from the home out to the street, and was shocked at the fact that we paid $450 for the service we received from DeHart.
