HVAC reviews in Chicago, Illinois

I recently had my old furnace replaced by TDH Mechanical, a 63-year-old relic that was still going strong. What caught my attention early on in researching contractors was that reputable brands are often comparable in terms of technology, so focus on building trust with your chosen company. The estimate process was hassle-free and transparent, addressing all my concerns. The installers showed up on time, were courteous and diligent, and answered my questions as well. I'm extremely satisfied with the service and confident that TDH Mechanical is the right choice for replacing my furnace – highly recommended!

This experience with TDH was outstanding from the initial meeting to the final installation. The sales representative who came out was extremely professional and made a thorough assessment of my needs. He presented his recommendations without any high-pressure sales tactics, which I greatly appreciated.

What impressed me most was his transparency and openness throughout the process. His follow-up with Jim to ensure I understood the proposal and had no questions showed that he truly cared about customer satisfaction. I had received estimates from four other companies, but TDH's commitment to exceptional service set them apart.

The installation team, led by Jose, exceeded my expectations. They arrived on time as promised, worked efficiently, and paid attention to every detail. Their professionalism was evident in their use of protective gear and thorough cleanup after completion. Overall, I'm extremely pleased with the service and would highly recommend TDH to anyone looking for a reliable and trustworthy company.

Wally and his team from TDH did an outstanding job. They replaced our entire AC system and furnace on a Monday, following up on a Friday quote that was significantly cheaper than what the larger companies like Four Season offered. We were extremely pleased with their professionalism and work quality, making us very satisfied customers.

Great service from these guys. They listened to what I needed and delivered a solid job on the water heater and furnace installation. Highly recommend, would choose them again in a heartbeat.

I've dealt with TDH for both my daughter's townhouse and our home, and I'm extremely satisfied with their service. The initial purchase prices were very competitive compared to other quotes I received. However, the most recent issue with the townhouse unit - a persistent loud buzzing noise that occurred about 90% of the time - proved to be more challenging. After four visits from their technicians, they finally resolved the problem. What impressed me was the professionalism and dedication shown by their techs, as well as the excellent communication with Jackie in the office and the field staff. They took my concerns seriously, responded promptly to my questions, and ultimately delivered a satisfactory outcome.

TDH handled my furnace and AC removal and replacement with excellent service, including a team that arrived on-site along with those handling the back office tasks. They offered a fair bid and stood out for prioritizing safety during installation. Their second visit four years later was just as impressive, delivering top-notch work at an unbeatable price - their craftsmanship is among the best I've seen in HVAC services.

TDH Mechanical provided top-notch service. Their technician, Wally, was extremely professional and thorough in his work. He exceeded expectations by ensuring our unit ran smoothly and efficiently. It's clear he took the time to double-check parts before installation. Overall, I'm very satisfied with their performance and would definitely recommend them.

Got a decent deal compared to ABC. The installation for my new AC went smoothly and I'm enjoying the savings. Clear communication throughout the process, no complaints. If you're in the market for a new system, this company is worth considering.

If you need reliable home services, look no further. Our experience with TDH has been exceptional - they installed a mini split system and replaced our boiler, both times delivering outstanding results. Wojtek's expertise is impressive; he knows his stuff. Highly recommended.

I recently hired TDH to replace my old A/C unit, which had stopped working over Memorial Day. The technician arrived just four hours after I called on a Tuesday morning. Given the age of my unit, multiple experts agreed it was time for replacement.

The estimate from TDH was fair and straightforward, and they made scheduling easy to manage. When my building's schedule conflicted with mine due to a surgery, they accommodated us by finding an alternative day that worked for both of us. Their professionalism and flexibility were impressive, considering the circumstances. I'm grateful for their expertise and would definitely recommend TDH to anyone in need of A/C services.

I highly recommend TDH for any heating or cooling issues. They offer top-notch service at an unbeatable price and consistently deliver excellent results. Their work is prompt and hassle-free, with a strong emphasis on honesty.

In 2023, TDH installed two new A/C systems in my home, which exceeded my expectations. I was so impressed that I recommended them to neighbors who all shared similar experiences. When my mother's furnace stopped working last January (2024), TDH responded quickly and had a new system up and running the same day.

Now, as we're selling my mom's condo in July 2025, the old A/C unit failed. However, TDH tech Ken arrived within 10 minutes and diagnosed the issue - a loose switch behind the panel that was causing a safety problem. The fix cost nothing, thanks to part of the furnace warranty. I'm not sure how many other companies would have offered to quote a new system in exchange for a repair. If you're in need of heating or cooling services, TDH is definitely worth considering.

Highly Recommended for Consistency and Expertise

I've had the same technician, Wally, work on multiple projects for 15 years, and it's a testament to the company's commitment to quality. The work he does is outstanding, but what really impresses me is the attention to detail in his installations – the radiant heating system in our floor and ceiling is a masterclass in design. It's clear that TDH takes pride in their service.

Wally also excelled at consulting on complex projects like tankless hot water systems. His recommendations were spot on, and everything worked out perfectly. When I've needed service over the years, Jacquie has always been responsive, fast, and communicative. The fact that few companies would even quote on our specific needs is a reflection of TDH's expertise. Overall, I highly recommend them for any HVAC work – they truly deliver.

I've had a ten-year warranty since my central air unit was installed in September 2015. Eight years later, it's failed - the compressor, capacitor, and electric box are all out. We reached out, and a technician arrived the next day to replace the faulty parts at no cost. The service was prompt and efficient. Given this experience, I'll definitely be using this company for any future HVAC work.

TDH provided excellent service, especially considering my ongoing heat issue. They were very responsive and sent mechanics multiple times during the winter to resolve the problem without charging extra for each visit. Ken, one of the technicians, was particularly impressive, explaining his work in a way that allowed me to understand HVAC systems better. The cooperative attitude and transparent billing made a big difference in my overall satisfaction with the experience.

Contracted TDH for a comprehensive HVAC replacement project in 2022, following a thorough evaluation of five companies. They came out on top due to their equipment choices and pricing. The installation took place over three days as scheduled, with no hiccups. More recently, I encountered an issue with my heating system and TDH responded promptly, sending Ken who quickly diagnosed the problem and replaced the faulty part himself - even going so far as to collect it from the supplier personally.

I hired TDH to install a new furnace after comparing prices with several other companies. Their service was top-notch - I appreciated their prompt responses, punctuality, and professionalism. The work itself looked great, although I couldn't inspect it closely. They weren't the cheapest option, but also not the most expensive. Overall, I'm pleased that they provided a quote, completed the job, and left my home tidy.

I highly recommend Wally at TDH Mechanical for their excellent service. After our AC and furnace failed, they came in at a fraction of the cost of the other quote we received. Wally took the time to explain the equipment and maintenance options, keeping me informed throughout the installation process. He provided top-notch work and I'm extremely satisfied with the result.

Impressive experience. Two tankless water heaters were installed with top-notch workmanship, clear communication, and fair prices. Will definitely hire again.

This home services business has excellent communication skills. They respond quickly to inquiries and schedule appointments promptly, as evidenced by Bernie's visit the following day after we called for a free estimate. His friendly demeanor helped us understand the benefits of their products and services.

Their pricing is reasonable and flexible, with options tailored to fit individual budgets. Jackie was particularly helpful in working out financing arrangements through our bank. The installation process was efficient, with Jose and Andres arriving on time and completing the job without delay.

The team's professionalism shines through in their attention to detail. They ensured everything was left in its original place before departing, demonstrating a commitment to quality workmanship. Tim, the company boss, is approachable and responsive, addressing our queries promptly and effectively. Overall, we had a seamless experience with this business.

I've been relying on TDH for years for various system installations, repairs, and maintenance. Their technicians are courteous, competent, and meticulous. The job sites are always tidy and finished to a high standard. They take proactive steps to prevent future issues by providing guidance and recommendations before problems arise. On this particular job, Mark did an efficient analysis on a 22-year-old furnace that turned out to be a costly repair compared to replacing the entire unit.

The replacement quote was received promptly, and we scheduled a new install for two days later. Alfredo and Vidal arrived right on time on a Saturday morning at 7:30 am. They worked diligently for four hours removing the old system, installing a new drain pan with a water sensor, and placing a new furnace in its position. I brought up the drain pan because it's an excellent practice that should have been done during the previous installation due to its location on the second floor.

I've personally experienced this issue before when my friends came home to find water overflowing from their evaporator coil drains, causing damage to their hardwood and drywall. The attention to detail displayed by TDH is a testament to their focus on quality. When issues arose during two previous installations, I had no hesitation in reaching out to them for assistance. While their pricing may not be the lowest, I believe they offer exceptional value – price isn't always what you pay, but it's what you get.

For me, the value over time is more important than a lower upfront cost. The service and expertise provided by TDH are well worth the investment.

I hired TDH to install a Trane/Mitsubishi mini split system in my home last November. I shopped around and got quotes from several contractors, but TDH was the best value. Bernie even gave me a quote on the same day - it's impressive how some companies can't be bothered to follow up.

Working with a third-party service to get an accurate load calculation helped us finalize our system specs. We ended up going for a 5-ton setup with two outdoor units and six indoor heads, which was pretty close to what TDH initially suggested.

Installing this type of system in an old brick home is no easy feat - it's a labor-intensive process that requires some finesse. Luckily, the team from TDH, led by George, were top-notch. They were meticulous throughout the installation, and their experience with the equipment and components was evident. George took the time to walk me through each component and line set location as we went along, and he was always polite and considerate of keeping our home tidy.

After the install, TDH quickly responded to my follow-up questions. I'm really happy with how everything turned out, and I'd highly recommend TDH for any HVAC needs, especially mini split systems.
