My father has used Sweet's for many years. They provide excellent service. They are experts. Thanks to Mark and Bob, especially. I have also used them, and they fixed my HVAC issues the very same day I called them. They went above and beyond, such as when my AC went out on a hot day. Thanks Sweet's! read more

They are slow to respond for appointments, was rescheduled multiple times. After work was done it was in correct, because they let a newbie unsupervised finish it. After complaining the owner came and fixed but had an attitude. They damaged my new cabinet and stove and left a mess for me to clean up. Very frustrated. read more

I live in Wilmette and during 2022, I needed to replace my entire HVAC system (2 furnaces and 2 AC units/coils). For years I had driven by the 'Sweet's' sign near downtown Wilmette, and since I like working with local guys, I gave Sweet's a call. I couldn't have been more pleased with Mark and his team and the work they did. Rates were very much in-line as well. The job was not an easy one as it was related to some backyard construction and required coordination with both the weather and a construction crew. During the different phases of the job there were several issues that came up where they came out in a rush to keep my heat/AC running. The timing got tricky as the weather was starting to get hot, and they made sure that we weren't without AC during the June heatwave. We never lost a step. I strongly recommend these guys, they were great to work with. read more

I am so happy to have been working with Sweets for about a year now, after working with other major heating and cooling companies on the North Shore for the past 20 years. Sweets has always been prompt, professional and has provided high quality service at reasonable rates, but they really saved the day when our very old furnace went out a couple days before Christmas. They came out immediately (and I didn't have to belong to a "comfort club" or pay any "emergency" fee, like some companies charge) but not only that, they had the new furnace installed before Christmas and before temperature plummeted to the teens. They went out of their way to drive to the western burbs to pick up the machine the night before install (which I only found out by chance, after the fact); they really came to our rescue! read more

Came to service units and shortly after the ac in main house stopped working. When we were bidding out work another tech came - I mentioned we just had units serviced (by Sweets) and he said that was impossible- the units were filthy and showed no signed of being cleaned and serviced.. They also came out to install a circuit breaker - they claimed this would fix our 2nd floor unit- they charged us over $500 for the work that took 5 minutes AND it didn't work for more than 15 minutes...the unit needed to be replaced although we did not use them. I called requesting to speak to manager about exorbitant bill and the tech (he was the one who came out) told me that he was not going to transfer me. Very rude! I told him I was not going to pay the bill and to have his boss call me- he never did and we just got a Notice from a law firm requesting immediate payment. I would not recommend this company to anyone.!!! Buyer beware! read more

Highly recommend Sweets. My very old boiler broke down twice in the past 60 days. Both times, Sweets could not have been more professional, more responsive, and more personable. Go nowhere else. read more

Our boiler malfunctioned at my Wilmette home this morning and our heat stopped working. I called Sweets from my Chicago office at about 10 AM, they called back with a guy ready to fix by 10:45 and he's out of the house by 11:30. Heat's back on, parts replaced, solid recommendations made for going forward, and he couldn't have been more qualified and pleasant. Well done, especially on a 10-degree day when I am sure Sweet's is swamped. Thank you. read more

They come to fix problems when I call them. They arrive on time. They've fixed things, so my HVAC works. My general impression is good. What's frustrating is that it always seems to cost about $1,000 to fix anything. Just showing up to tell me that they need to come back to fix something costs over $100. Maybe this is the way the HVAC industry works. read more

We had an AC issue which they came out and fixed. 4 weeks later we had the same exact issue, called them about it and they came out and let us know we had to reset the unit by flicking a switch. Easy fix, took about 3 minutes of time, and I was happy...until he bill for $80 showed up. Why not just tell me over the phone to flick the switch? Or, better yet, stand by the work you just did 4 weeks ago? Absolutely brutal customer service and approach. Will use literally anyone except for them in the future. read more

RUN from this company!!! Total RIPOFF!! Their annual maintenance fee is $135 as compared to market rate of $89!! Furthermore, the serviceman they sent - 'John' was almost an hour late (with no courtesy call), was very rude and dismissive, left in 1/2 hour, yet I was charged the full $135!! Make sure you check your own filters/pads and BUY YOUR OWN!! Their mark-up is 150% over internet and big box stores. That goes for ANY parts: thermocouples, flame sensors, etc. BUYER BEWARE! Please do your homework when shopping for an HVAC company as this one is what they call a 'real clip joint' not to mention poor customer service!! read more

Our furnace died on a Saturday night, I left a message and they were out by 9 the next morning! They spent a lot of time diagnosing the furnace and tried really hard to keep it and were great when we had to replace it the very next day! Thank you! read more

In December we had a slight leak in the feed line connected to my boiler and I had no idea how to fix it. They came in and fixed the problem. I am not sure how fast plumbers are expected to move but at the rate I was paying I would have expected them to move a little faster but thats not my gripe. Two months later I get a bill showing service took place two months earlier. They charged me quite a lot for the parts that they needed to complete the job. I called and spoke with someone and they were kind enough to reduce the cost. Hey maybe I am wrong and they really do pay really high costs for their parts but I felt like they were changing quite a premium for the materials to do the job. This was sorted out over the phone and I was done with the issue, fairly satisfied. Next, I receive a pretty condescending email shortly after the phone call stating all of the reasons why they need to charge what they did in the original bill and then tells me a different new total which was slightly different from what the man on the phone said it would be. After a few not so pleasant emails back and forth a new bill arrived on my doorstep with a two month late charge added to the bill and an even different final cost for the parts. When I told them (again) that this was the first bill I had received and asked if they had any proof that they sent out bills or reminders to my house, phone, email or whatever. I was told that they keep no records and the bills are all done by hand, and the person in charge of doing in them certainly did it in December. Although there was some type of automated bill reminder system that they were unclear about. This is all been waste of my time. I would shy away from a business that treats its customers like this. But hey, Just my opinion. read more

Had a terrible experience. They charged me a small fortune only to install the cheapest and lowest rated AC unit. It has broken down twice in the first 4 years costing me over $1,000 in repairs. They didn't honor the warranty and the owner is beligerant. read more

Was hoping we had found a locally owned partner to service our heating and air conditioning needs for many years into the future. Paid for a preventative summer service visit and all checked out fine. Two weeks later the unit seems to be leaking freon. (Coincidence ?) Another service call and another fee. They did a nice job diagnosing and fixing the problem the second time, but not willing to waive the first service call fee. Too bad, I guess the short term fees are more important than the long term relationship. So long Sweets:-( read more

Can't comment on their ability to fix things, but they just went above and beyond to help me fix my furnace while it's -18 degrees outside. Called them late in the day and they sent someone out within 15 min. Told me what the problem was, but that they don't have the parts in house to repair immediately. They didn't charge me for the visit and then explained to me exactly what part I needed (including the model number) so that I could track down another company ASAP. Who does that anymore? Kudos to Sweet's for going above and beyond. read more

We have two water heaters side by side. In Dec, one began a small trickle which we ignored given the busy time of year. In Feb, we called Sweets and asked them to fix. When I came down to basement, the unit was being drained and disconnected. He said it could not be repaired. We explained that we still had hot water-he seemed surprised. We said we would get back to them regarding the replacement and would see if the one would suffice for time being. It worked fine to have one water heater. 6 months later, yesterday, we decided to get the second heater replaced. Whilst the guy was here installing the second heater, the first fully functional one "broke". I left for work with heater intact and received call from my husband that the second heater broke while he was installing the one next to it. Owner said just a coincidence, bad luck- as the heaters are the same age. WHAT??? He disconnected and drained that one- our fully functioning heater of two years... until he arrived. I am very upset as $1200 ( Now 2400) is a great deal of money for our family. I called (admittedly very upset) several times seeking resolution. How could the heater break not the same week, not the same day, but during install of the one next to it and be just a coincidence? Perhaps it was cracked accidentally - things happen. But this doesn't sit well with me at all. The owner told my husband he would call the police on me if keep calling. I've referred this biz to friends and family bc its important to support local business BUT NEVER again! You decide if its a coincidence and if the owner handled appropriately. Caveat Emptor.Thank you. read more
