Update on July 17, 2026. It is nice of the owner, Mr James Cox, to reply... James: your tech came and all he did (besides his constant: "call my office for a new unit") was spraying (my) water on my 2.5T Trane... THIS IS NOT "MAINTENANCE"... To say: "your system is on borrowed time to say the least and extremely inefficient the older it gets." is immature. the unit works FINE, is very efficient, as I write it. I am a seasoned Senior Design Engineer (has one USA patent granted) and know "something" about "something". I design things for all to use them and for some to service them. 2.5T for a small house like mine is possibly an overkill but that explains its lasting. 40 years of working AC unit is unheard of, correct, but it is ME who decides about replacement or maintenance, and your tech (still working there?) did NOT do the maintenance I've paid for. So, he did no technical work and you owe me that 99(?) bucks :-) read more

I stopped using Besco Air 2+ years ago. Since then my "problem" boiler has had zero problems. One star because some of the technicians working for Besco are honest. read more

My request for an estimate was immediately answered and within a couple days Joe from BESCO Air was at the house to take a look. Once Joe spent about 45 minutes inspecting the 24 year old horizontal install, he had drawn a picture of what I had for his analysis. He described the issues and how to resolve them verbally before sitting down and drafting an estimate with 3 options for us to review. BESCO technicians Julio and Gio arrived with Joe 2 weeks later to get started. They reviewed the scope of work to demo and install this second floor attic project There was a lot of work to do and the install took the entire day. Julio and Gio stayed until everything was perfect. I have a Trane S9V2 60,000 BTU High Efficiency Furnace that replaced an oversized BTU furnace that would overheat in the winter and stop working. The Air Conditioner was replaced by the Bosch Inverter Ducted Split 2.0 Heat Pump. Both are high efficiency technology meant to save energy costs and perform quieter, faster, smarter. The quality of the install is key, no matter the various well known equipment brands to choose from. BESCO will provide professional and skilled teams to transform your HVAC systems worry free. read more

We should have been shown a pressure reading performed with a refrigerant gauge before being told we needed to replenish 9 pounds of coolant (est. $2500) or replace our AC unit entirely. There was no evidence provided, to suggest that our unit was leaking refrigerant. The tech sat in front of our house for 20 minutes before ringing our doorbell. I felt there was a lack of transparency. The goal was clearly to sell us a new unit rather than repair it. This isn't the same company from years prior. read more

Salsman was attentive and very knowledgeable. Quick to follow-up to questions. Products were very satisfactory.

I highly recommend Besco Air. I purchased a new Trane furnace and central air system from Besco one year ago. I have waited a year to write this review and am convinced they have excellent customer service. I am a licensed Stationary Engineer (boiler operator) in Chicago and have worked in building maintenance and HVAC for over thirty years. Our family moved into our home six years ago. At that time we found the furnace and central air system was 35 years old. Replacing it was the first improvement I wanted to make. I requested bids from three different companies, including Besco. I asked a colleague who is a licensed pipe fitter and experienced estimator to review these proposals with me. Although Besco's bid was not the lowest, we agreed it was the clearest and that the equipment and material specified was of the highest quality. Being experienced in the field I found it refreshing that Besco didn't try to 'up sell' us. They provided what our family needed. I believe paying for quality equipment and service from a reputable firm like Besco Air will serve our family well for many years to come. I hope this review has been helpful to you and your family. read more

Jim, (Cheech) is the the most knowledgeable technition & extremely professional we definitely recommend him & this company.

The service Besco Air provided was well beyond superb. Ed Pfeifer worked with me to ensure I'd received a cost that wouldn't become a hardship to my budget. Robert Szarkiel and Alan Farias (technicians) were on-time, professional and proficient. They impressively dismantled and removed the entire system; replaced and installed an energy efficient HVAC combo within 6 hours. Great work guys. Thanks again! read more

Besco Air Inc. Heating & Cooling - Great Besco Service crew - Heating & Air Conditioning/HVAC Near Me - Chicago, Illinois

We had good experience with Besco. We had two furnaces and two air conditioning units installed by them for our 115 years old house. We had few other quotes but Besco pricing was the most reasonable. Our sales rep Mike was very responsive with all the questions we asked in a timely manner. We also needed to get a trim removed in order to put the new furnace into our attic and Mike was able to get us a handyman to do the work who was able to work around the scheduling. Installing two furnace and air conditioning units took one full day. There were 2 crews (4 techs total). All four techs were nice and answered all questions we had. They showed up around 730am and worked til 6pm. No complaints and the systems are working fine. We love their warranty on product and labor. Not many companies offer this great warranty. The one thing to note is we had a very minor gas leak from one of the joints in one of the furnace the next day. We called Besco and they sent someone the same day to address the issue. The issue has been resolved. read more

We called for air conditioning cleaning earlier in the season. Did the job. However, there was an additional "clean" on some water gizmo that was a 15'minute job and over $200. read more

Our basement heat stopped working. We were getting heat to the upstair apartments but not the basement. This occurred several times before. The last time was over 20 years ago. It is usually the pump that goes out. Well we called Besco to come out and look at it. A man named Ed came over and said he would contact someone a the company that could figure it out. He took photos. He told us he would contact us in a few days. That was over a year ago. They never got back to us. Apparently, the new tech guys aren't trained on old heating systems like the old timers were. read more

They came and serviced our furnace unit for a cleaning, very reasonable with their prices. The office was very helpful in scheduling our appointment. Reliable and on time. read more

I purchased a high efficiency HVAC system from Besco over three years ago for my 2 story cape cod in Edison Park. I felt compelled to write this review at this time because only because I have gradually learned of the things that were done improperly from other furnace maintenance companies thru the years. As Besco prices are higher than most, I reasoned I was paying more for their high end products and expert installation. But beware - they will cut corners and short change you wherever they can. When Ed Pfieffer first gave me the estimate, he included, in writing, to relocate my furnace air return to the front of the unit, instead of the rear where it was bizarrely located. A welcome observation as I was oblivious as to the implications of this. Unfortunately, after the new Trane furnace was installed, the air return remained where it was originally. Second, I purchased a two stage furnace along with a two stage thermostat, but the old thermostat was only wired for a single stage furnace. Two stage furnaces work best when they have the one extra wire. To rewire my thermostat so this expensive furnace could work at its most efficient level, would have only required pulling 10 feet of wire vertically from the basement directly up to the 1st floor thru the existing holes - maybe 15 minutes of work. But this was not done. So my investment in this technologically advanced furnace could not use its energy efficient air recirculation technology to its fullest. Instead, the installers simply rigged my furnace to cycle the blowers for 15 minutes once the thermostat reached the triggering temperature. Lastly, my basement furnace was only 1 of 2 HVAC systems in my house. It should have sufficient ability to heat both the basement and the first floor. It took another home estimate from another company to point out my basement had only 1 vent blowing air from about 10 feet from a furnace intake - hardly enough distance to stir the cold air from the corners of the open basement. A simple fix of sealing that vent off and creating one or two new ones further down the exposed duct-work would have been enough to create sufficient warm air circulation. Certainly a professional HVAC company as big as Besco installer would have caught this. But alas, no. So I'm stuck with a cold basement and half-assed two stage furnace that's cheating me of its advanced technology. My advise, skip Besco and go with a smaller local installer. read more

Very nice people to work with. However, we had our first technician out to fix the leak on our condenser pipe and he used the incorrect silicon as a "patch" for our problem. The leak persisted at which we had a second technician out to make an attempt at it. He too was unsuccessful. Because I was selling our unit and didn't care to buy a new AC, I had explained that from the beginning and I wish they had told me that the issue would be unrepairable and that I'd have to buy a whole new unit. I spent $290 to have them fix nothing and ended up giving our buyer a credit to replace it anyways. What a waste. I just wish they were transparent from the beginning so I would have saved $290 and they would have saved two technician trips to my house. read more

I'm turned off by the hard sell for membership for service. I have a sing"3 stage furnace. I have an 800 square foot apartment. You're trying to sell me a monthly membership or annual membership that would be the same as a full house or business or building. You're suggesting there are penalties for not having a membership even though you installed my furnace only 4 years ago. I do NOT like this sales tactic. You're making me feel ripped off and wishing I used someone else for the install. Not great. NOT GREAT read more

I had 5 companies quote me a replacement AC unit with some duct work for return air. Besco came through with the best price. Ed Pfeifer the sales rep. was great to work with, explained the work in detail and answered all my questions. The labor and parts warranty were also better then the others quoted. The morning of the install Cesar and Manny were here 7 AM sharp and promptly went to work. The guys were very professional did a great job and left everything spotless when done. Being fairly knowledgeable of what needed to be done I'm completely satisfied and I highly recommend Besco Air. Job well done! read more

Besco Air Inc. Heating & Cooling - Heating & Air Conditioning/HVAC Near Me - Chicago, Illinois

We had a Mitsubishi mini-split heat pump system with 6 heads installed in our 1887 brick house we're rehabbing. This was a complicated job for lots of reasons related to the age of the house. From the first detailed visit by Bob the sales rep, to the measuring and installation, to the warranty work, Besco was impeccably professional. There were problems with the equipment and installation that Besco quickly took responsibility for and resolved without cost or complaint. The fact that there were some issues demonstrates to me better than if this had been problem-free just how good a company Besco is. They had absolute integrity and went above-and-beyond to make sure I was satisfied. The system works great with zero complaints two years after the install. Unequivocally recommend. I continue to rely on them and trust them for scheduled maintenance. Bob, our original sales rep still serves as our contact with Besco. read more

Unfortunately a local company earned a 1-star rating. I called them on the hottest weekend of early June. Their technician, Cheech, arrived promptly, was very personable but assessed the situation incorrectly. He said that the blower motor could not be replaced on this furnace without great effort and expense, due to this furnace being too close to the 1st floor furnace. It made sense to me at that time, and the charge was $200 for this information. Due to the extreme heat that weekend, I bought and installed window a/c units in each of the bedrooms in the 2nd floor apartment, which cost $600+ and a number of hours for installation. But a couple of weeks later, I called a different company (a 1-man shop) and he came over and changed the blower motor on this furnace without issue! So I called Besco's sales guy to explain the situation and complain that I paid them $200 for an incorrect assessment and $600 to provide window a/c to my tenants, when I really didn't need to. He said he would talk to the owner and get back to me that following week after the 4th of July. It's been a month, an no return calls from Besco. They were very quick to charge the Sunday service fee but they gave me wrong information and caused me additional expense and time. So, no thanks to Besco, the central air in my upstairs apartment is working just fine, but I am $800 poorer because of them. D. Ross read more

We just bought our house and the condenser was stuck between the house and a fence with barely an inch to breathe. There was more than 10 degrees difference between downstairs and upstairs. The Besco team came out and gave us multiple options to move it and replace for more efficiency. The next week(!!) they came and replaced and moved all in a day. The team was kind and helped answer any questions. Our house is now even in temperature and the AC unit is so quiet! Thank you! read more

Our AC unit broke down after a series of service calls over the years and we decided to get a combination furnace and AC unit for efficiency. So we decided to get a Trane system (Don't mess with Texas) because of the positive online consumer feedback. We called three authorized dealers for quotes and Besco was in the mddle of the pack, however, we decided to go with them because of the exceptional customer service. During the consultation we felt good about Joe, it was a feeling of integrity and subject matter expertise that he displayed. A big plus with the system is that the Nexia thermostat is internet connected and it's very nice in that you can control it by Iphone or laptop. The thermostat can even control your smart home (if you have one, we certainly don't). After the installation, when we had questions, (even during the holidays) Joe still responded to our emails within an hour or so.....now who can beat that? We waited for a year pass to write this review to make sure that our system was done right and we are very happy with it! Hopefully Besco will not disappoint us in the years to come. Heck, hopefully we don't have to do this again until 2030. read more

Joe Pedota, of Besco Air, has consistently provided to us excellent and responsive new installation, service and suggestions for improvements to our complicated HVAC system for an old home in Evanston. Not only were their prices competitive or less than 2 other outfits (have purchased 1 furnace and 1 AC unit from them for 2 separate properties), but there was no baiting/switching and everything very straightforward as described. Joe went above and beyond to analyze and suggest ductwork routing errors and sensor/control issues that have plagued our house for 20 years. We have used in the past numerous HVAC companies for properties in Evanston and Chicago and now know the difference between a conscientious customer service oriented company and the others. Highly recommend. read more

This is my second time to use HVAC service provided by Besco. Based on very satisfactory experience couple months ago for not related issue, I didn't hesitate this time to call them. The phone call was answered by live person and we were able to set appointment the same day. Our furnace upon return home from the short trip, we lowered temperature to 64F, was able to heat only to 67F when burners stopped to work and furnace was just running on idle and fan on auto. Sergio, maintenance person, called 15 min before and was on time at our door. He was a professional in his approach and work. Sergio was trying to explain his work process and steps in effort to diagnose and fix the problem. The heat was restored and problem was fixed in reasonable time and price was right. I believe that Besco deserve to be recognized and refereed to anybody looking for quality HVAC contractor. read more

I called them as my AC was not working .They charged 90$ for coming which is more than all other companies .Then the guy added 200$ for "cleaning " before asking me if I wanted this service At the end the AC was not working and the only thing the guy wanted was to make us pay for a replacement , pushing for that Very unprofessional and Felix Gonzalez was unpleasant Stay away from company , they just want you to take your money read more

ONE HOUR OR LESS. My review is not based on any work done, but on what has become common practice for many businesses. Their time is valuable and billable yours is not. When making appointment, explained the work requested. Non emergency during heating season, no problem with 2 week wait. Took the time and rearranged schedule expecting problem to be solved. Technician arrives, verifies work as originally requested, gives quote based on hours needed. While deciding whether to have work done, I was informed that they allotted him only one hour for the call and I would need to call for another appointment to actually have any work done. SO UNLESS IT IS AN EMERGENCY, OR THEY CAN FIX IN THE ALLOTED ONE HOUR, IF YOU WORK BE PREPARED TO TAKE TIME OFF TWICE. read more

We've been loyal customers of Besco for 7 years. We've now spent 4 months trying to fix our heated floors. Not only did we receive the attached message with many expletives on an invoice from a Besco employee (what a gift for paying $800 to a company and receiving that in retune), but after finally getting the new pump installed for our floor heat earlier this week it stopped working after 1 day this week. At a loss of how to proceed, we had previously had excellent experiences with the companybut this has been exceedingly challenging and offensive. I've never paid thousands of dollars to be told to "eat one" and "blow me" and still not have resolution on our heating issue. Would very much appreciate management resolving our issue. read more

Our whole condo building has had the worst experiences with this company. I suspect they intentionally create issues just so they can keep coming back to quote on issues but never actually fix them. Ultimately we had to hire other companies to fix their "work" and one of our issues we solved on our own with a simple YouTube video. read more

Had my complete HVAC system overhauled in October of 2008. Besco sold me a 95% EFU Furnace XV95 and a 3 Ton compressor XR14 which has lowered my heating and cooling cost to 1/3 of what I had previously. Have enjoyed wonderful operation and savings over almost 10 years. So this season everything was working just fine until the outdoor compressor ceased to run. Both compressor and fan were not moving or providing cooling throughout the house. So I called Besco since they installed the Trane system 10 yrs ago. Besco came out the same day and I met the service tech Rob at the front of my home. I went through the issue and Rob could not have been more thorough. Rob also explained what he was going to do and the steps he was following in his troubleshooting. So after determining that the Thermostat was good and the furnace and blower motor were providing ample air, we began to look outside at the outdoor compressor unit. Rob did an inspection and removed the service panels. What was found that Mice...yep Mice had chewed their little hearts out on the wiring that allows the compressor and fan to run. Rob showed me the chewed up wire and he had to open the compressor rear panel to find where the other end of the chewed wire was located. Rob found the other end and used a wire nut to reconnect the two severed ends. Once he repaired the wire and Walllah the Compressor started right up. I was happy, as a clam that there was not a major failure, but just a reconnection of the chewed wire. Rob also checked the performance of the compressor and it had not leaked any of the original freon and we were back in business. I was charged a nominal and honest amount for the repair and my faith in Besco Air was restored. I would rate them as a knowledgeable service team and an honest company. IMO Besco Air is the best and provided excellent service. read more

Used Besco for my hot water heater. The communication was quick, efficient and they were available at short notice for an extra cost. They use a text message system which confirms appointments and allows you to know what technician is coming to your house. Safety was at the front of their mind. Would recommend. read more

I sent my design plans over a week ago at which point they told me they wouldn't be able to review and get back to me until the following week. No problem i waited to then get a call that they do not do new installs unless high-end and was told they usually quote double. Pretty annoying to hear from a business owner then why advertise on Yelp if you not able to take on jobs from your local customers. read more

My AC compressor blew out on a very hot Sunday. We called Besco for help; and they were able to come out in a couple hours to investigate. Turned out the compressor was blown. We have young kids and wanted the functioning ASAP. Besco was able to do a temporary repair immediately, and went above and beyond to squeeze in a replacement install on a busy Monday. read more

Besco damaged my outdoor A/C unit when moving it and is refusing to repair. Machine now rattles and this is verified by their technician. Their solution was to charge me for a brand new motor on a 5 year old machine. Jim, the owner, would rather worry about saving a buck than taking ownership for his crew's misfortune. First and last time customer. read more

We moved from a townhome in the city to a house in the suburbs last fall. Besco does our furnace and AC care. They are knowledgeable, thorough, fair and nice. Roberto recently checked the AC. He was particular helpful because he took extra time to explain the details of his inspection/work. Also, he helped me better understand how the system runs in our new home. Very good learning for me. Roberto is great! read more

A great HVAC company. They did a great job of replacing our unit in a very timely manner. Workers were polite and made sure we knew all about the system before they left. Highly recommend this company. read more

Very efficient and professional. Knocked out a full furnace/ AC installation in half a day. I am very happy with the results and I'm feeling smarter than I deserve to feel. read more

The worst place to ever call. Blood sucking scavengers. I would not recommend them at all. They over price everything they quote you on. The salesman are told to do so. Look up the equipment before you ever think of calling theses scums. I would recommend four seasons . read more

We sought out 3 quotes when deciding on whom to give the job to as it was a huge expense for us. We had the furnace, the AC, and the hot water heater all replaced as the house we bought had 25+ years on all of the components. We also purchased a new air humidifier/filter. Besco was by far the most responsive, professional, timely, and knowledgeable. And their customer service is beyond reproach. We went with them for the job after Joe came over and thoroughly explained each component, it's efficiency, how it works, etc. Joe was wonderful and spent as much time as we needed. Great customer service! We went with a Trane 97% efficiency furnace and 13 SEER Trane AC, and a Goodman hot water heater. There was a tiny snafu when the installers turned the water back on abruptly rather than the required slowly while running a steady sink stream in the basement after shutting off the main water valve. We had a new hot water heater installed hence them needing to cut the main water for install. We had a water hammer incident, but Besco paid for the plumber (of our choice) to come out and fix the faucets that were affected. They took responsibility and made it right with no questions asked and remedied it immediately. All is well that ends well and just some sediment that needed to be removed from the faucets. Aside from that, the work done was high quality by guys that seemed like savants, and we highly recommend the company for their superior customer service. Oh, also, the AC unit they installed had a louder than usual humming and they brought in a new unit and replaced it without issue. In fact, they were the ones that noted that it sounded too loud. Sometimes the fan blades are off during manufacturing and it happens. The whole job was just over $9K. We waited to post this to see how much we would save on utilities. The old stuff was so inefficient. Our ComEd bill ended up being about $100 dollars less each month during the Summer and the gas bill is almost half what the previous owners paid per month. Lastly, Besco's administrative staff fills out all the rebate paperwork that ComEd and people's gas requires to send a rebate. We received the rebates about 6 weeks after the install. While the two other quotes were less than Besco, the equipment they were pushing was also of lesser quality. Each HVAC place pushes their favorite euipment. We researched Trane and are very pleased with the quality of the euipment and the energy efficiency. You can barely hear the furnace while standing next to it. read more

I have been dealing with a troublesome boiler during a very cold winter, and this company has been very good to deal with. My boiler needed a new transformer, and the repair was fairly expensive. Initially I was disappointed because the boiler continued to cause problems, but Besco was great about coming out and making further adjustments and repairs until the job was finished correctly. This is not an inexpensive company, but their service is very good and they stand behind their work. Happy to refer them to other people. read more

After being taken to the cleaners by American Weathermakers for an A/C issue, I stumbled upon Besco Air through a work referral for furnace repairs. While both companies were responsive, Besco was quickly able to identify the problem and offer a range of solutions depending on how much money we wanted to spend. While a lot of companies take the opportunity to use scare tactics to convince homeowners into buying something that's out of their price range, the rep from Besco identified the fact that we had a growing family and probably would not be living in our current townhouse for an extended amount of time and suggested a more affordable option. A few days after we made our selection, they did the install and modified some of our ductwork (all included in the price, no secret upcharges). They were very neat and organized and you would have never even known they were there had it not been for the brand spanking new furnace in the basement. My husband is not the handy type, so we were sure to purchase a maintenance agreement on the furnace and they threw in a free check-up on our air conditioner as well, even though it had been installed by another company. This is definitely my go-to for heating and a/c/ read more
