For years we were on Roberts' prepaid maintenance plan. Recently I asked the owner about a charge…read morefor a humidifier repair and he mocked my inquiry. 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.

Used Roberts on 3 major jobs so far. A complete boiler install at a school, 4 A//c units at a…read moreschool, and 2 residential units at a house. These guys are complete professionals. Their work is superior to other HVAC companies I used. Keith is the man!!! Rest assured in these guy, they wont let you down.

Really enjoyed the service provided by Michael…read more Our Furnace is old, granted but he tried to find a solution that would fix it. Ultimately it required a replacement, as the parts are just old. I took in other quotes previously to see what the comparison is and I thought Michaels quotes for really good brand of Carrier was better than some other quotes that I received. He came the next day from when I asked about his service. In/out for the replacement it was a good experience. I thought he ran a good shop, was trustworthy. I previously had him service my AC unit as well. He said it was still fine for now and not to replace just yet. I'll definitely have Michael on speed dial for HVAc

I just wanted to express my gratitude to your company in general (21 year customer) and to Marvin…read moreD. in particular for the prompt response to the "chirping" noise in my vents after my new furnace installation last September. 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!

Customer service is always very professional but continuous problems with the a/c and now furnace leaves me feeling cold and I cannot recommend.

See pics I file a dispute with thumbtack and still waiting! Update as of today 1/20 I spoke to Alex the manager of duct professor and that he supposed to get me a refund for the scams that his techs did back then but, never happened. He is upset about my reviews and won't refund me any money because I left bad review. It doesn't work this way Alex. I want more people to be aware the way that you and your techs provide services. I was a part of your scam but not let that happens for other people. Even if you tried to offer me to give you a 2nd chance for cleaning but I am not TRUSTING you at all. You should do the job correctly at the 1st time. I was lucky that I found out after I replaced my furance. Also, the three kids that you sent me to do the job let them be more professional when they get into people property by wearing the shoes cover to have some respect for the people that lives in the house. Also, order them a good flash light instead of using their phone as flash light! what a scam? Please be present at the time of service don't be victim like me. Also, make sure to check the filter and the return duct base after few days of cleaning to see if any debris left over from cleaning I am not able to upload photos after the service was provided by duct professor crew. You can check Google review since i posted on.

Nick replied quickly when I asked about getting my microwave repaired. At 16 years old, he recommended replacing it, and helped me ensure the one I bought from Lowes was the correct make and model. The tech that came out texted me when he was an hour out, which was a helpful amount of time because it narrowed the window but not by so much that if I had been busy I wouldn't have been able to break and let him in the house. Did a great (quick) job with install and cleaned up the kitchen area / took the old appliance out of the building after. Already using them again to help diagnose / repair an issue with my partner's washing machine. Fingers crossed that one won't need to be replaced! But I feel that I can trust this company to be honest there.
