Last year I needed help with my a/c ducts. Today, my whole a/c ststem was shut completely down. I…read morewas lucky that Ryan was able to make it to my home, 30 mins after I called! I feared my whole system might have needed to be replaced as I followed DIY advice on the internet and NOTHING! Ryan had it diagnosed in about 15 mins or so. Buchner's truly is a caring abd honest business at a level that is rare nowadays. Both during last year's visit and today's visits -they were quick, affordable, honest and even educational. I feel like I know ALOT more about how these systems work and... I know who to call when they don't! Thanks Buchner's (and Ryan!)! I can't thank you enough. ---------------- Update 12/11/17 We had Ryan come out today to look at our hot water heater that stopped working. He did a terrific job. It seems about once a year we need help with something in our 1914-built home. Each time we call Buchner. They are so dependeable- our home is almost like a TV commercial- I told my wife we had a hot water heater problem. Her response, "Did you call Buchner?!?" Its funny now because Ryan fixed our hot water heater. He was clear what was wrong, showed and explained to me the problem, and he repaired it quickly, perfectly. He even gave me advise on what caused the problem and how/what to think about this if problems re-occur. It seems like everytime we think we have a very costly home repair we have to deal with, Buchner sends someone out who is honest and does the job right! In 2014 it was our home's venting system. 2015, it was the house heater. 2016, thermostat. 2017 (today) the hot water heater. All fixed promptly and professionally. They are a blessing. As a disabled veteran, I do not make a fortune. Truly every penny counts. With Buchner, every dollar spent has been a dollar well spent. learn something new about my home with every visit. Friendly and thoughtful office staff too! I cannot express my gratitude enough to be sble to trust a company over the years, to get the job done right and without costing a fortune. Thank you!

This is NOT the company it once was. The level of customer service has truly diminished. I had an…read moreappointment, and their tech arrived 40 minutes early. Keep in mind that during the winter months, they cancelled with me several times because my call was not a high priority. Not to mention their guy had just come out two weeks earlier to check my furnace for leaks, and we talked at great length. However, today EMILY called to say that since I could not make the appointment, they can never put me on the schedule again. Such a horrible level of customer service. It's okay for them to cancel, but because they are there early and I cancelled, it's never scheduled with us again. No problem, I am a homeowner, hard working, and damn sure will take my money and service elsewhere. Not to mention their best technician are no longer here. Take time and do your research; everyone's experience will not be mine, and I don't need to deal with companies like this or EMILY!

When they came for the install, they informed me that the original humidifier was not the best fit. Rather than installing it just to get the job done they paused.

This shows their dedication to customer satisfaction and making sure the customer has the best product to address their needs. Highly recommend them.

Nonetheless I gave Harmonic a chance and am happy I did. I'd give them 4 stars just to break the trend, but that wouldn't be fair as they really are the best service provider I have seen in years. They communicated well both on the initial call, and during the appointment. The dispatcher Liz actually called to tell me they'd be running 30 minutes late and confirmed with me that that would be okay. Nice touch. Tony (an owner) came out at the new time and properly assessed the situation and presented a couple solutions. As I am a well-informed customer, (maybe too informed for some) I am always appreciative of techs who are not scared off by my technical questions and don't try to snow me. Tony had no problem that I knew the jargon and the systems in play, and was a consummate professional. He even stated that he wouldn't be suggesting a maintenance program as it was obvious I had that in hand. The price for the call was very fair ($79) and the price for the service performed was also fair. This alone sets them apart from most HVAC people in the western suburbs where up-front gouging is the norm. Too many companies both big and small want to charge you crazy prices just to show up and then have the stones to put the screws to you from there on. He never came close to suggesting I replace my 18 year old system. For HVAC folks, that's test number 1. LOL It's clear to me that Harmonic is building a reputable business that will provide a valued service without all the greedy nonsense. They are not a bare-bones cheapest-on-the-block operation by any means, but they are also clearly not out to rip you off like so many others. I have no doubt they will be around for a long time. I recommend Harmonic and will call them again when I need an HVAC pro.

This company used to be called Marco Heating and ​Cooling, but I guess when you get so many bad…read morereviews, you have to change the name of your company every so often. A tenant called me and said her furnace was not working. I called Marco and met him at the house. He took the panel off the furnace and explained that the blower motor was bad on the unit. It was a part that cost over $300. The next day, he came out to repair the furnace . Upon telling me that the job was completed, I went over there to look for myself. I opened the panel and was shocked when I saw that the same old blower motor was still in the furnace. I called him to tell him I knew he had ripped me off. He was speechless for a few seconds before he finally told me that it wasn't him who installed it. It was his employee. I was suspicious so I asked the tenant what the person looked like that came in to do the repair. She told me it was the same guy that I had met with the day before, Marco! Let's face it, in the HVAC business, most customers wouldn't know an igniter from a blower from any other part in the furnace so it's real easy for a dishonest operator to lie to get you to pay for something you don't need. For example, a furnace might not be operating properly because a sensor is dusty. To correct that, the repairman just needs to wipe the dust off. An honest guy would in fact, wipe the dust off and only bill you for the service call. A dishonest operator can charge you for any number of parts. My guess is within a couple of years, Maximum Heating and Cooling will have another new name. When it does, and as long as it is operated by Marco, I will leave a review for the new company as well. This is a shady operator. ​

After being quoted a frankly outrageous amount for a furnace and air conditioner replacement by the…read morecompany that recently acquired my long-time service provider (AWE), I was understandably skeptical. The recommendation felt premature with the actual condition of my system, that was serviced each year. At the suggestion of my next-door neighbor, I contacted Curtis Climate for a second opinion and I'm exceptionally glad I did. Their team conducted a thorough evaluation and, with refreshing candor, made it clear that I was in no way, shape, or form ready for a full system replacement. Instead, they proposed a practical, effective solution that addressed the issue without upselling and entire system. The professionalism, technical competence, (showing me what was wrong) and integrity were evident throughout the process. In an industry where trust can be hard to come by, Curtis Climate distinguished themselves!! I wasn't simply looking for another service call - where they used technical terms to overcomplicate, I was looking for a long-term partner. I've found one.

I called JJR Heating & Cooling and Josh came out within 45 minutes. He explained what the problem was and replaced the part. I did not need a whole new system!! (It's 16 years old). I know I will probably in the next year or two, and when I do, I will call them. I'm so grateful that this wasn't a major expense at this particular time. I so appreciated his honesty.
