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!

Mid Oct 2024 they moved my 3ton A/C unit over and further from house making it easier for me to keep clean. It's taken me some time to write this review as I'm still recovering from surgery. Come Spring or Fall I'm planning to renew my maintenance contract. They come out twice a year to check HVAC and clean everything up. Again outstanding Customer Service every one works with you. END RESULT very happy customer. Highly recommended!!!

This company is GREAT! After another company replaced my furnace and messed it up by miss matching…read morethe plenum size and furnace I got McHenry to do it. The other furnace was crap and only lasted a year before the blower failed (because of the pressure miss match caused by the plenum mismatch). They replaced the furnace with a good one, AND got it up off the floor like it SHOULD have been. In addition to correcting the plenum, they put a NEW and correct filter housing on it. That doesn't seem like a big thing except the prior company had some dummy install a filter housing with the screws facing IN to the slot where the filter sits making it a real pain to replace. So ya, I definitely recommend them.

I truly can't say enough great things about this company! They are incredibly responsive, easy to…read moreschedule with, and their pricing is very competitive. The owners are absolutely wonderful and genuinely care about their customers. They were recommended to me when my AC died on the hottest day of the summer, so I cold-called them in a panic. Even though I ultimately needed a full furnace and AC replacement, they temporarily charged my AC for free to get me through the weekend while the new system was ordered. They then overbooked themselves to make sure my installation happened ASAP, which I greatly appreciated. When a small snafu occurred, they handled it immediately and made things righ,t including going above and beyond what I would expect a company to do to make things right. Since then, I've replaced my AC, furnace, and water heater with them, and also had a whole-house humidifier installed. They service my AC and furnace twice a year, and drain my water heater and clean my dryer vents once a year Their Comfort Club membership is absolutely worth the cost for the value and perks alone. Between the outstanding customer service, quick scheduling, responsiveness, and competitive pricing, I would gladly give them more than five stars if I could!

We will definitely be using them again. A million thank you's to the team for the incredible help in a pinch!!!

On July 20, 2022, I purchased and closed on a Newly Built Home from the Dr. Horton Builder…read more The Carrier HVAC Unit was installed by Combined Services HVAC. In December of 2022, the HVAC unit Malfunctioned, and the Heater stopped working. Since this was a Brand New Home and Combined Services HVAC installed this unit - Andrew from Combined Services was sent to my home and was able to get the heat going. In July of 2024, Combined Services installed a Reme Halo System but failed to install the transformer (I have the original box this system came in and noticed the transformer is still in this original box - purchased from Combined Services). In December of 2024, this Unit Malfunctioned for the 2nd time, the technician from Combined Service informed me there is a broken part on this unit - and they need to order and install the missing part - an "inducer cooling wheel." This system also made large noises and the air distribution is completely unbalanced. I no longer hear the noises, but the air distribution is still extremely poor - the Primary Bedroom & Bathroom receive most of the air and or heat even though the vents are closed.

This is one of those rare reviews that is split into two. To start off with, this is NOT about the…read moretechnicians. This is about the sales people, specifically about one. I've used Combined before and I have to say the techs that came out were spot on, professional and courteous. This is about the behavior or lack thereof of customer service of a certain salesman. I called three weeks before to schedule an appointment, this was on a Friday (May 9, 2025). The receptionist took me number and said the salesman is out but would call back ASAP and even on a Saturday if he could. I thought wow, that's service. Boy was I wrong. Three weeks went by without a telephone call from a salesperson. During the fourth week, from that Friday on Wednesday ( May 28, 2025) of the fourth week, I called Combined again and she transferred me to the salesman who happened to be in. I asked him why he didn't call back and his response was " I have your info right here, I meant to call Back" that was a red flag but I decided to ignore his comment. We set up his visit for that Friday ( May 30, 2025) two days from Wednesday's call, for 3 O'Clock. Come Friday 3 O'clock, no show. 3:30, 3:45 no show, no call. I call Combined to find out what happened and they transfer me to the sales desk. His buddy picks up the phone and tells me that my salesman is in but in the toilet so he put me on hold. This "sales guy" answers the phone while in the background I hear him buckling his belt, WTF I'm thinking to myself? I ask him why he wasn't here for the appointment and he says that he was coming after 3. What? I ask him what does that mean after 3? Could he give me a time estimate and he raised his voice and said " I said after 3" I was stunned, I took time off, had a medical emergency with my dog, and this fool's response was after 3 while buckling his pants. I got agitated and wanted a normal response of an actual time and he responded "you are getting off on the wrong foot with me" ,I'm thinking to myself, who does this guy think he is, I',m the customer and he's talking to me like I was a child? He's representing a company, talking and raising his voice to a customer and not even allowing me to say anything constantly interrupting me and trying to talk over me. Before I could ask for another salesperson he said something nasty and rude and slammed the phone down on me. I was shocked!! I guess I interrupted his day and he didn't need my business nor my subdivision's, my recommendation to the HOA board and to my neighbors is ZERO. I guess the company has no controls as it shamelessly allows their representatives/salespeople to abuse and talk back to customers. I recommend the company hire some professional real salespeople that know how to talk to customers without insulting them. In the mean time I guess they really don't care about making money they must have too much of it.
