A neighbor uses this company so we decided to hire them to do maintenance on our unit. The man who…read morecame out told us our HVAC hasn't been properly cleaned by the other company we used for years, he told us that he needed to use a hose to clean it and our balcony would get flooded with the water. He also said it would take several hours, we weren't able to have him do anything the day of our appointment because we had to leave in 2 hours. He left and said we'd get an email to reschedule our appointment. We didn't get an email so I reached out and never heard back from them. On top of that, our AC stopped working after he left, we hired another company and found out Beckman Bros intentionally broke our unit!

They said they would check it in a few weeks to see if it was leaking. When they came back, they said we had lost about 4 ounces of refrigerant and showed me where they found the leaks. They gave me a quote to replace the A/C. I checked with a few other contractors and they were more costly than Tom's quote. We have used them for many years and i am very confident with the quality ofwork they do. We made an appointment to have the system replaced. They came out on time, did the work efficiently and cleaned up when they were done. Tom, Tommy and Marcus are very knowledgeable and kept us informed every step of the way, I would highly recommend them for your heating/cooling needs A big "Thank you" to Tom, Tommy and Marcus.

Please read before doing business with this local "family business" in our town. This morning,…read morewhile leaving Grayslake, I was cut off in traffic after making a left-hand turn onto rte 120 from hwy 45. As I was getting up to full speed + at least 10pmh over the speed limit on this stretch of road, I was passed by a van doing at least 70 in a 35-40, then the van slammed on the brakes so that I would have to as well and all of my belongings flew into the front seat; I admit, I wasn't on my best behavior either as I sped up when I noticed what he was obviously & illegally trying to do. This act was followed by continued bullying as we both drove west on 120, with the right lane being closed a short distance ahead due to road construction. The van (picture attached) then drove about 45, riding shotgun next to a construction vehicle, knowing that this vehicle would have to move to the right; he was hoping I would be cut off a second time. When I called the number on the van to report the driver, he laughed at me and called me a "F**king C**t" (when I came into full view of him as he merged onto 94E he was on older gentleman with gray hair & a moustache so I can only assume he was Tom Sr.). I would NOT want this person in my home--NOT ever. He doesn't respect or have regard for others, esp. women or Veterans (I am both--my car is clearly marked with both). We use Advantage Heating & Cooling for all our service needs, and they have always been extremely professional. Maybe that's why they have quite a few 1-star reviews on Google citing erratic driving & rudeness.
