    Called Cahill out to help with a room above our garage that was too cold in the winter and too hot in the summer. They recommended a split system for the room and had a quote to is within a couple days and the work completed within a week. The professionalism and craftsmanship displayed by the installers was second to none. We have had our home for five years and have had a number of contractors do work for us, and they were head and shoulders above everybody. The price was very fair and we could not be happier with the job that was done. I recommend Cahill highly.

  • Review 2 (2024-12-23 - Rating: 5)

    Miguel and his partner were amazing! Professional 100% of the time. They took every effort to make sure that the install was done correctly and cleanly. I would absolutely recommend Cahill and specifically Miguel to do any heating or cooling installs or maintenance for your home.

  • Review 3 (2024-12-27 - Rating: 5)

    Great service from Cahill as usual! Did a great job on new furnace installation, price competitive and solid workmanship. They answer all your questions promptly and explain the options and tradeoffs.

  • Review 4 (2024-12-26 - Rating: 5)

    Great price, definitely way lower than a competitor we checked. They installed a TRANE, and research shows this is a very good brand. From Holly the sales lady, who was always quick to respond to all my questions and was very helpful, to the the team that came in to install. Every person was extremely competent and pleasant to work with. For the first time in a very long time, I felt that the company really did appreciate out business! Thank you Cahill. I most definitely recommend this business!

    Cahill did a great job (even considering my high expectations) with my full furnace and AC replacement. They explained well all of the choices on the front end, helped me pick the right system for me (not the most expensive), and Miguel and his team installed it and they cleaned up the area after themselves. I write this 3-4 weeks later and Im still 100% satisfied with my choice.

  • Review 6 (2024-10-30 - Rating: 5)

    We had our AC and furnace unit installed just a few days ago. Very happy with the process. our technician Miguel from Cahill was outstanding. They installed the unit and got rid of the old one, very clean job, explained how to connect the thermostat to the WiFi in details and helped us connect it to our phones for convenience. The financing options were very helpful so was the extended warranty on the job. Will use Cahill for yearly maintenance now. Overall, would highly recommend Cahill.

  • Review 7 (2024-12-22 - Rating: 5)

    Cahillā€™s service was fantastic. They texted me back right away, sent an apt confirmation shortly after and showed up within the hour to fix our furnace. You could also track your driver which was a cool feature. Jason was able to identify and resolve the issue quickly and walked me through preventative measures I could take. The cost was very reasonable, especially given the weekend. I would highly recommend Cahill.

  • Review 8 (2024-11-30 - Rating: 5)

    Cahill had the best price for a new furnace, the estimator explained everything very well and was responsive and prompt with any questions. Install team was polite and efficient and cleaned up the work area superbly.Highly recommend.

  • Review 9 (2024-10-15 - Rating: 5)

    Cahill came out the same day and was able to quickly diagnose and repair our furnace. They took the time to explain the issue and answer my questions. They also cleaned other parts to help the furnace function properly.We would recommend them to anyone in their service area!

  • Review 10 (2025-01-06 - Rating: 5)

    Couldnā€™t be more pleased with Miguel and his partner for the work they did replacing my old furnace. Clean, fast, and efficient. Will use Cahill for another install Iā€™ll be needing soon.

  • Review 11 (2024-11-13 - Rating: 5)

    I have used Cahill for years. Jason was here today and did an excellent job of prepping my furnace for winter, letting me know just what he was doing and checking everything before he left. He was on-time, polite, and clearly knowledgable. I recommend these folks to anyone wanting to be sure their furnace is safe and ready for the season.

  • Review 12 (2024-11-21 - Rating: 5)

    Amazing customer service. We werenā€™t current clients. The boiler wasnā€™t working. The man I spoke to asked me to send a picture of our boiler to make sure they sent the right technician. Thankfully he was able to squeeze us in and get the boiler fixed today. We will now be using Cahill for service.

  • Review 13 (2024-11-12 - Rating: 5)

    Got a flyer from this company, decided to check them out. Was able to schedule a service appt for a furnace fall review via email. They sent a text when the tech was on his way. Jason was great to work with and knowledgeable. I would work with Cahill again!

  • Review 14 (2024-11-14 - Rating: 5)

    Our gas boiler gave up the fight after 24 years. We researched Angieā€™s List, Nextdoor, and Yelp to read reviews. Cahill had consistently excellent reviews so we asked them to provide an estimate along with another well known company. We selected Cahill and we are extremely pleased with the entire process of getting a prompt estimate, scheduling the install, and the two technicians who did the installation (one was Flavius) were outstanding in all respects. We are very happy we chose Cahill and will be recommending their Lake Bluff business to all friends and family who need heating and plumbing services.

    Steve Romero with Cahill Heating, Cooling, Electric,Plumbing and Sewer. Arrived on time to service our 4 furnaces, Steve is knowledgeable at his trade, this knowledge reflected by how he detailed each areas of each of the furnaces checklist with me. My husband and I are impressed with this young man, I will reach out to Cahill when it is time to replace the 4 current systems, I will request Steve R for the Spring AC & flushing of our systems. Thank you for sending out a no nonsense technician that cares and does his job well.

    I have used Cahill for maintenance and repair of my HVAC systems. They have always been prompt, friendly and responsive when I have an issue. Their technicians are top notch and the office staff is great to work with. Whether it is an emergency repair or regular maintenance, I am very happy with the service and support I get from Cahill!

  • Review 17 (2024-12-19 - Rating: 5)

    Great company. Second time using Cahill. Technician arrived on time (and texted 15 minutes before arrival.) Jason replaced 2 central humidifiers, removed all the waste and even turned out the lights when finished. Final bill was exactly as had been quoted. Professional service all around. These are my go to guys for HVAC work. Wont be looking elsewhere. Highly recommend.

  • Review 18 (2024-10-28 - Rating: 5)

    Miguel showed up as a specified time along with his team. The team started the job (installing furnace and air conditioner) right away. They were professionals and polite answer my questions clearly. They cleaned working area very good too after completed installation. Miguel and the team did excellent job and I am very satisfied the work they did. Miguel and the team is the Best! Thank you!

  • Review 19 (2024-11-06 - Rating: 5)

    Jason was our technician. It was easy to schedule an appointment, they let us know when they were going to be there, he was very courteous, knowledgeable, fast, and fixed issues we didnt even know we had. Will definitely be using Cahill again in the future for all our HVAC needs.

  • Review 20 (2024-11-17 - Rating: 5)

    Cahill HVAC technician was able to fix my Trane furnace while two other companies could not and just wanted me to buy a new furnace. Thank you Cahill for your fast, professional and honest service. Highly recommend this company.

  • Review 21 (2025-01-06 - Rating: 5)

    Cahills team demonstrated exceptional professionalism during the installation of our Trane heat pump and backup furnace. Under the leadership of Miguel, the project manager, the team ensured all our questions were thoroughly addressed and provided detailed training on the operation of the new system. They went above and beyond to accommodate our specific preferences, such as the placement of the exhaust and the seamless integration of our existing Aprilaire whole-house humidifier. We are extremely satisfied with the quality of the installation and configuration of our Trane HVAC system. The entire installation process was executed with first-class expertise and attention to detail.

  • Review 22 (2024-11-23 - Rating: 5)

    Hayko and his team did a great job. On time, friendly, thorough and professional. Walked us through everything we need to know about our new furnace. Highly recommend Cahill.

  • Review 23 (2024-07-11 - Rating: 5)

    My ac went out on Saturday, 4th of July weekend. Had a company come out, but they didnt have the part. Called Cahill, spoke to Brandon, the owner, (the owner answered an after-hour service call, Amazing!) about replacing the part but also told him I would be looking to replace the ac and furnace. After asking some pertinent questions, he gave me a fair quote over the phone to replace them both and said they could install Monday. They came on Monday and installed both units and did a great job. Fantastic customer service, and the install techs - Kyle, Brandon, and Adam - were great. This is definitely a company that cares about their customers and will go the extra mile for them. I wholeheartedly recommend them!

  • Review 24 (2024-11-05 - Rating: 5)

    First time using Cahill for our seasonal furnace tuneup. Excellent service! Knowledgeable and timely. Weā€™ll certainly have them back in the spring for our ac maintenance. Thank you, Hayko!

  • Review 25 (2024-10-18 - Rating: 5)

    When our family bought our home we knew our HVAC system would need replacement in the next few years. We got a few years out of the system and late in the summer knew it was time. We contacted several companies. Cahill was professional, responsive, and financially reasonable beyond the others! The team was great to work with start to finish in completely replacing our system. We had 90 degree days in the summer and in the Fall approached frost requiring heat. Here is a comment I hear from my family often and also make myself: It is just so comfortable in here!

  • Review 26 (2024-11-13 - Rating: 5)

    Techs were very helpful and diligent. Iā€™ve had many HVAC guys before, but they are the best. Highly recommend Cahill. They went up and beyond with their attention and service.

  • Review 27 (2024-11-17 - Rating: 5)

    Recently I had a problem with my gas furnace due to damaged heat exchanger. As operating the furnace paused hazard, I urgently contacted Mr Brandon at Cahill Heating and Airconditioning Co. He was very nice, thorough and accommodative of the urgency. He discussed the issue in detail and explained the solution patiently. He promptly scheduled the repair. Repair was done by technician Mr Hoyke E. He was very professional, efficient and thorough.

  • Review 28 (2024-07-11 - Rating: 5)

I was impressed by their professionalism and dedication to customer satisfaction. First and foremost, their team is incredibly knowledgeable. They took the time to understand my needs and provided insightful recommendations. Their expertise was evident in every interaction, and I felt confident that I was in good hands throughout the entire process. The quality of their work is outstanding. Cahill delivered on every promise, and the results were nothing short of exceptional. They went above and beyond to ensure that everything was perfect, and I couldnt be happier with the final outcome. They kept me informed at every step, promptly addressing any questions or concerns I had.Overall, I highly recommend Cahill to anyone in need of their services. They are a company that truly stands out in their field, and I am grateful for the exceptional experience I had with them. I will undoubtedly turn to Cahill for any future needs and will refer them to others.

    As soon as it got cold the heater decided to take a break. Called Cahill and they were at my house within an hour. An hour later and everything was great. The tech was pleasant, knowledgeable and friendly. Most importantly the house was warm when my wife got home.

    Cahillā€™s service appointment was flawless and easy. I called and made our annual appointment for a couple weeks out. The day of service appointment, I received a text advising Toli was on his way and the text included Toliā€™s photo. Toli arrived a few minutes early and quickly went to work. After he cleaned the furnace, he gave me an update on my system - good to hear that all was well.

  • Review 37 (2024-12-11 - Rating: 5)

    Cahill replaced our failing 20-year-old Trane furnace with a similar high-efficiency Trane model, as well as the old humidifier and air cleaner. They were responsive and easy to work with, pricing competitive with everyone in the area, and the installation completed efficiently.

  • Review 38 (2024-06-18 - Rating: 5)

    This was our second experience with Cahill and both times they helped us out of challenging situations. We were really impressed with the reasonable cost for their emergency service call at 9pm on. Saturday night and the included return visit on a Sunday morning. Often working with service companies, you face exorbitant prices, but Cahill is fair, reasonable, and trustworthy. Weā€™re so happy to have found them and used their services.

  • Review 39 (2024-06-11 - Rating: 5)

    Had a great experience with Cahill. Their owner covered a scheduled site visit that an employee couldnā€™t do last minute, and then stayed in touch with us through the whole process of replacing AC, furnace and water heater. The technicians were timely and did solid work as well. Overall it was the communication from Brandon, and the making of a frustrating situation into a good one is what drove our decision to stick with Cahill.

  • Review 40 (2024-12-18 - Rating: 5)

    Hats off to the team at Cahill, especially their top technician Chaun. My mom had a blockage in her septic system we took the advice of a friend we called Windy City rooter while they did clear the blockage they also broke the main sewer line in her crawl space resulting in gallons and gallons of sewage to be dumped inside the crawl. While they didnā€™t charge us for clearing the blockage, they did send an estimate of $14800, to replace all water/sewage piping in the house. Not only did they dump sewage but also caused flooding on the first floor which I now have a claim into the insurance for all of the water damage they caused. Needless to say the team at Cahill came out fixed the problem in a matter of hours and did it for over $10,000 less! If you need any plumbing assistance these are the guys to call, we canā€™t thank them enough. Great job to Chaun and Tyler of the Cahill team! On a side note I never leave a review, but these guys deserve credit for the amazing job they did!

    Joe was an amazing technician! Cahill helped us last minute when we had our AC stop working on a 98 degree day! They came out within the window of time they said they would (even though they were over booked)! Joe was kind, a great listener, and really helpful with replacing a part that he had on hand. Got our Tran unit up and working in under 30 mins! We highly recommend Cahill for your next HVAC experience!

    My air conditioner was not working and I called Cahill. Holly was fabulous and got someone out that very afternoon. Josh couldnt have been nicer and fixed our issue. We plan on updating our furnace and air conditioner and you better believe we will be calling Cahill for that.UPDATE: Today, we had Cahill replace our Furnace and Central Air Conditioner. Miguel and 2 others were excellent, polite and friendly. They worked diligently and were very professional. They were attentive to my questions and made sure they answered everything. They also made sure that their shoes were not tracking in any dirt and even laid drop cloths where they were coming in and out to their truck. We also had them install a purifier to keep odors and allergens at bay. We are very happy with the decision to have Cahill do the work. Call Holly if you need sales or services.

Honest does pay and we plan to continue having our equipment serviced by Cahill.

    I rarely write reviews, but I would be remiss if I did not for this outstanding company!In a word... If you need to replace your failing AC as did I with a 27 year old unit that was starting to freeze and lose refrigerant, call Cahill. You will be happy you did!Ken from Cahill was the 3rd company to come and give me a quote.Back story...I almost went with the first company, as they sent someone on a very hot Saturday (when my AC threw a tantrum early that morning and no one else could come). The tech was courteous, thorough, and gave me a quote on the spot. I was pretty much set to go with them.However, I wanted to get a Trane quote (since I have a Trane furnace). The temps cooled right after, so I decided to wait until a Trane estimator could come the next week.So, the next guy was from a Trane approved dealer. He was nice enough. But when he started by asking what the first company quoted me, that gave me pause. When he finally gave his quote, it was WAY over the first company. AND over the figures provided on Tranes own site!He said, I know were higher, but we offer a lot more that goes into that price, yada, yada...Well...Thanks, but no thanks! He just did a superb job selling me on the first (non-Trane) company!And, as noted, I was prepared to do that. But I saw there was another Trane dealer close by and decided to wait a few days until he (Ken/Cahill) could come. The weather was being very cooperative, so I didnt have to be in a hurry.Anyway, Ken had a quote for me within a couple hours after he left. It was a no-brainet decision. I was getting a Trane AC for not appreciably more than the non-Trane (although a recognized brand). And the Trane equipment has a much better warranty.I had to wait a couple weeks until the install but it was worth it! The two installers were very professional (one had 31 years in the business and the other was the owners young son, who looked to have been trained very well!). They spent almost 4 hours making sure everything was working and looked just right.So, make it easy on yourself... Call Cahill and get a top notchTrane AC with top notch installation to match! Plus the bonus of a peace of mind warranty.

    Im a new client of Cahills and couldnt be happier with the choice I made. I hired them to install a new furnace and heat pump.

    Our furnace went out when it was -9 outside. I called Cahill first thing in the morning and they sent a technician out by 10:30.

    Great pricing and professional installation of brand new Trane furnace. We interviewed multiple Trane authorized dealers in Lake county , IL and adjacent counties and Cahill heating was the best option . Cahill came with a perfect review from other clients . Installation was done with professional staff and after a week had a visit by the representative ( Holly) for presentation of warranties and rebates . Amazing experience. Would recommend anyone looking for a great furnace installation to for sure consider Cahill heating.

    AAAA++++ Cahill has been servicing our HVAC needs for 25+ years. They are always professional, thorough, competitive, and sensitive to their customerā€™s needs. They stand behind their work, and I can always depend on them to do a good job. This year we had intermittent problems with our A/C condenser units. Cahill doggedly pursued the root cause and remedied our problem. When it became time for us to replace our hot water heater (today), Cahill was on the job, competitive, meticulous, and provided great attention to detail which is always a plus when plumbing is involved. They were careful not to nick or dent our walls, and they made sure to put down a carpet runner to keep from tracking in any dirt or mud. Kudos to Cahill for another job well done.

    Cahill installed a heat pump at my home 7-14-23. My dealings with those in the office and the installers were all very professional. Everyone was responsive to my questions. Very happy all around!UPDATE: The heat pump was not working when the colder weather came. I had heat from my furnace but not the pump. My understanding is heat pumps are not common in this area (yet), so it took a couple of visits and information from Bosch to get wiring and blue tooth straightened out. I appreciate Cahillā€™s communications and the technician, who worked diligently and all is working well. Iā€™m particularly happy that my furnace will not be needed unless the temperature drops to minus 4 degrees.

    Quick response. Fair pricing and overall excellent service. Installed two new furnace units in my home during the recent brutal cold spell. They will definitely be my go to for my future HVAC needs.

    I found out that my A/C was not working at 8pm, called Cahill and had a call back within minutes. They were out the next morning, got my A/C back up and running quickly, were honest about the repairs needed and had it all done for a great price. Thank you, Cahill!

    Ive been using Cahill to maintain HVAC units both at home and at my workshop for several decades now. They are a class act, very professional, knowledgeable and responsive. I would use no other company and recommend them highly.

    Great experience with Cahill. Called them at 2pm for non-working A/C. They came out 8am the next day. Tech Hayko was top notch. He explained everything and knocked out the repair in just over an hour. Thanks Cahill and Hayko!

    First time using Cahill and I have to say theyā€™re miles ahead of their competition. Not only was their service tech extremely informative throughout the entire diagnosis, he also did an amazing job. After spending years working with an HVAC company out of mundelein that recently closed, Cahill showed me the caliber of service I was missing. I immediately recommended my family to them as well.

    Cahill hit the ball out of the park from their initial proposal to the installation of the air and heating units. They also presented a multitude of legitimate finance options which came in handy for our situation.The GM - Ken presented the proposal in a clear and concise way. Gave us 3 options for the job and did not pressure us in any way. Two of the other three companies I received a quote from were more intent on getting the most out of us as possible.Brandon in Sales helped us procure the Financing that best fit. He was helpful during the entire process.The installers - Hayko & Phoenix showed themselves as true professionals- they both displayed a tremendous amount of professionalism. I truly appreciated the patience and time that Hayko took in explaining and walking me through everything that was done.After dealing with multiple air and heating companies in the past 27 years - at this point I can confidently attest that Cahill stands way above the rest.Thank You.

    Just moved to Lake Bluff and needed new Furnace & AC. Lots of options but I chose Cahill. Im so glad I did. Incredible customer service, professional service people and best-in-class quality. Ive since had them install a water heater and most recently, they came to fix the pilot light on my gas fireplace. I highly recommend Cahill. Theyre amazing!

    From the management down to the technicians. Your treated like a family member. They are on time, respectful, professional, from commercial to residential work, I would recommend them to handle any project you can throw at them . Ive used this company since 2008 and still use them today . Just had a Cahill technician out today and he was in before I knew it and done before I could think about what the issue was. Of course the technician showed me the issue . A/C contactor burned up . Had the part on the service truck . Replaced as needed and done . Happy kids at camp with the A/C up and running in less that an hour.
