No issues with the technician would did spend a bit of time taking the oven apart. He tested the control board and said it was the issue, collected my service fee, then an hour later sent an estimate for more than the price I paid for the oven two years ago. I can look at the part online and they are wanting to charge double, plus $500 for roughly the same labor that they just spent doing for a $65 service fee. So while they were quick to respond and nice enough... I'm still up a creek with less money and more wasted time.

The kicker is today an hvac man I trust thoroughly (a family friend and the building engineer of a downtown office building with special expertise in hvac systems) did the a/c checkup and eyeballed the entire hvac system and reported the humidifier solenoid was not connected so it couldn't work. Here's his photo showing the loose wires. I'm no expert but I trust him and it appears Roberts not only dissed me but also didn't do the job right.

If you're planning a home remodel, I would not recommend hiring them. The quality of their work was very poor. The painting was substandard, deadlines were repeatedly missed, and the project kept getting delayed. On top of that, the owner frequently pulled workers off our project and reassigned them to other jobs, causing long delays, while still expecting payments according to the schedule. My experience was extremely disappointing. If you're looking for a company to remodel your home, I recommend choosing someone else.

It took multiple "tinkerings" to resolve the problem. What I really appreciated was that as soon as I called, Marvin adjusted his next day's schedule and came out to my home and worked several hours, not leaving until he had thoroughly tested and verified that the problem was resolved. No vague promises of "I will see when I can get to it", he arrived the next morning and stayed until the problem was resolved. BTW I was very impressed by Marvin's HVAC knowledge, as well as his patient and friendly attitude while working in my home. Thanks!

Arrival time was excellent. This was a maintenance visit for 2 units with an additional chronic nagging electronic issue with one of them. I found Dominick to be very professional. Their quoted price was fair and he spent extra time corresponding with the manufacturer to precisely diagnose what was wrong with the circuit module. He was honest and forthright about the longevity of my existing unit and I did not feel pressured (which tends to push me away). I would recommend this terrific company confidently without reservation. I will plan to use them for maintenance going forward and especially when my unit needs replacing down the road.

DO NOT HIRE. If I could give zero stars, I would. I originally hired Duct Professor to fix my home…read moreAC, and they ended up charging me over $1,300 for six incredibly frustrating visits, a string of misdiagnoses, and unauthorized repairs. The first two technicians they sent spent hours troubleshooting but completely failed to find the issue. Instead of properly diagnosing the system, they installed a non-OEM control board without my knowledge or consent. This unauthorized part risked causing further damage to my electrical system through power fluctuations. When that didn't fix the AC, they guessed the AC contactor was the problem and replaced it twice to no avail. It wasn't until the sixth visit that a senior tech finally came out and identified the actual root cause: a damaged low-voltage power line leading from the AC to the house. This is a fundamental issue that should have been caught on day one. Dealing with a broken AC in the middle of summer is hard enough, but enduring a dragged-out, six-visit ordeal with a newborn baby in the house made their incompetence a complete nightmare. Ultimately, because they left my system compromised, I had to hire an entirely different, independent HVAC company to actually fix the problem. To make matters worse, I sent a detailed email to Duct Professor management outlining these failures and requesting a refund for the misdiagnoses and unauthorized parts. They completely ignored me. No follow-up, no apology, no attempt to make it right. Save your money, your time, and your sanity--look elsewhere.

So, that seemed a little outrageous. Contacted nick and from the onset knew that this would be a different experience. Let the glazing begin! Cannot say enough about nick and the business that he runs. Was a pleasure to work with him diagnosing the issue (he took a look at the photo l, asked me to retrieve the model number on the stove/griddle and saved me that absurd 210 fee) - gave me variable pricing between generic and OEM parts, and was quick to schedule service rather than having a lead time of weeks out like the other companies were requesting. On top of that, he went out of his way to take a look at my dishwasher as a courtesy as it was giving us an error just before he left our home. People like nick remind me that there remain honest and hard-working service people out there. Super glad that I found his company and would not hesitate to have him out again to perform any repair as needed. Thanks again, nick!
