The service was surprisingly affordable, especially considering the time required. Both John and his technician were courteous, skilled, and efficient.

John and his team got rid of the whole ventilation system and installed a new one in my place. They showed up on time, kept me informed, and made sure they didn't disrupt my living space too much.

I recently had KTS Heating & Air Conditioning Repair come out to fix my air conditioner, which had suddenly stopped working due to the heatwave. The service was top-notch from start to finish.

The technician arrived promptly, and I appreciated that he didn't make me wait around. He got straight to work diagnosing the issue and demonstrated a clear understanding of his craft. His explanations were straightforward and easy to comprehend.

What impressed me most was the technician's complete transparency regarding costs. He not only identified the necessary replacement part but also showed me its price, which was refreshing in today's industry where customers are often caught off guard by additional expenses.

The technician was diligent about ensuring I wasn't being sold on any unnecessary upgrades, and for that, I'm grateful. When I gave him the green light to proceed, he worked efficiently and completed the repair well within the estimated timeframe.

My air conditioner is now working like new, and I couldn't be happier with the service. Overall, KTS Heating & Air Conditioning Repair has earned a strong recommendation from me. The technician's professionalism, combined with his genuine concern for customers' needs, made the entire experience seamless.

We're first-time customers who ended up needing emergency help with our air conditioning unit after using another service. We called KTS at noon and were able to get someone out by 4 the same day. From scheduling to the service itself, they demonstrated excellent professionalism, punctuality, good communication, a friendly demeanor, efficient work, and thoroughness. They also did a great job of explaining our unit's condition to us. Their pricing was extremely reasonable and fair. If you need a trustworthy, honest, and knowledgeable AC expert, I'd confidently recommend John and his team over any other company I've worked with since moving to Chicago.

John and KTS are the best in the business. We had a complicated issue with our hot water heater that required some serious troubleshooting. John and his team were relentless until the problem was resolved, even if it meant coming back multiple times. He kept his word to us, even when the issues persisted. The quality of work is impressive, but what really stands out is how genuinely caring and trustworthy KTS are as people.

They got it right, which is a rare thing in my experience. The team showed up on time, did the job efficiently, and explained everything clearly. I'd hire them again without hesitation.

KTS provided top-notch customer service. Their technician arrived promptly, diagnosed the problem on-site, and made the necessary repairs. The service provider took the time to explain the issue and address my concerns, ensuring a satisfactory outcome.

Great job! They delivered on the spot and their price was fair, considering I'd gotten other estimates. The warranty came out slightly better too.

I booked the heating system replacement and they arrived right on time. Their installation was top-notch, leaving everything spick and span afterwards. They're very responsive and do excellent work. John even went above and beyond by adding a filter slot for easy maintenance - it was a big improvement over my old unit where I had to open it up every time I needed to change the filter.

Before he left, John double-checked that the new unit was registered with the manufacturer so it'd be under warranty.

KTS and John were fantastic. They arrived on a weekday, worked tirelessly until late at night to ensure everything was functioning properly. Their professionalism and dedication are top-notch, and I highly recommend their services.

I needed emergency heating help after my apartment froze solid, forcing me to leave for nearly a week. The next day, John arrived promptly and discovered the issue was a blocked evaporator coil. Fixing it took under two hours - impressive considering the severity of the problem. He did a great job, and I'd definitely hire KTS again, highly recommending them without hesitation.

I had a serious issue with my heating system that just wouldn't stop flooding the basement. The city's work on the sewer outside my house was causing chaos. I tried several HVAC companies, but none of them would even return my call until John at KTS got back to me. He showed up super early - 7am on a weekday - and figured out what was going on with my system. He fixed it right away and gave some good advice for future maintenance. To be honest, my old system is basically done for; when I need a new one, I'll definitely be reaching out to KTS again. They were really responsive, professional, and even helped out a neighbor by jumping their car while they worked on mine.

I've had a consistently excellent experience with John from KTS. They helped me schedule regular maintenance on my air conditioning unit in a remarkably short timeframe. Within an hour of reaching out, I received confirmation of an appointment, which was even sooner than anticipated. On the day itself, John arrived promptly and demonstrated a high level of professionalism. He took care to verify that my unit was ready for the upcoming season, explaining each step he took along the way. His pricing was fair and competitive, and I've gained significant confidence in KTS and John's ability to meet my heating and cooling needs.

KTS did a fantastic job with my HVAC system. Their service was incredibly prompt, with clear explanations of what needed fixing and how it would be handled. The team was professional, courteous, and genuinely cared about our needs. With three years of reliable maintenance and one emergency fix, I wholeheartedly endorse their work.

Excellent service from a highly knowledgeable technician who left the work area spotless after completion. I'd highly recommend this company and will likely do so again, having already sent them to several friends.

Here's a rewritten version of the review:

I was pleasantly surprised when I called four different companies for a boiler service and they were the first to respond with a quote, book the appointment, and fix the issue. In contrast, previous experiences with other companies have been disappointing. The team from this company exceeded my expectations and earned our trust - we'll definitely be calling them again in the future!

KTS really stood out from the previous contractor. When they arrived, they pinpointed a new issue and showed how the other company had botched the job. They then offered me an unbeatable deal to get it done right. I'm sticking with them for all my HVAC needs moving forward. Their quick response and solution were much appreciated.

I've had a consistently positive experience with Jon and his team at KTS, who I wholeheartedly trust to deliver on their commitments. When I first reached out to Jon about an AC unit issue, he advised me to return to my previous contractor due to warranty obligations, demonstrating his focus on fairness rather than personal gain. After being repeatedly taken advantage of by the same contractor, I eventually turned to Jon for help. Despite having no availability for a week, he still managed to dispatch his team the very next morning and saved me a significant amount.

What truly sets KTS apart is not just their professionalism, but also their integrity and dedication to putting clients first. Their character and values shine through in everything they do. I have no hesitation in recommending Jon and KTS to anyone who wants reliable and trustworthy service - particularly real estate investors.

John and his team have been top-notch. They installed mini-split air conditioning systems at our place and were extremely polite, went above and beyond to get the necessary parts despite a tough supply situation, kept the mess to a minimum and caused minimal disruption, and quickly resolved the couple of minor issues that arose after installation. Their professionalism and responsiveness have won us over - we'll definitely be calling them for any future heating/air conditioning needs!
