Report
General wear and tear kind of damage can happen to any system, but it’s important to notice the signs before they end up shutting your system down when you are depending on it. Some of the signs that may precede an AC breakdown include leaking refrigerant around the evaporator coil, frozen coils, lukewarm air coming from the vents when it should be cold, knocking or banging noises coming from the main unit and jumps in your energy bill for no apparent reason. If you see any of these signs, don’t wait long before you call for help.

One of the larger HVAC companies in Chicago told me I needed a new boiler to the tune of $8000, but something smelled fishy to me. On a referral from a friend, I called TDH, and their technician came out and checked out my boiler and told me there was nothing wrong with it. He also told me that the other company pays their technicians COMMISSION on anything they sell, producing a huge conflict of interest. TDH did some minor maintenance on my boiler for a low/reasonable rate and saved me close to $8000. Thanks TDH!

TDH Mechanical were the BEST! I got 8 companies to bid for a new HVAC system. It took me several weeks to narrow it down. It came down to TDH, Four seasons, Sears, and a local company. After the first week, we were ready to go with Four seasons, (the total charge was over $10K with Lennox products), they told us that they were quality work, and they were the only ones who offer 10-year warranty for both parts and labor.

Being our first time, we thought this was the best deal! One day before making an appointment with Four seasons, Sears and TDH called to set an appointment to see our old HVAC system. We were going to decline, but somehow we said okay. We decided to give Sears and TDH a shot, so we didn't make an appointment with Four seasons yet. Best decision. Sears rep came first, looked at everything, had a presentation, then gave us the quote.

Their quote was less than $9K, basically the same with Four seasons.their warranty was even better! I have the contract/quote somewhere, but it was something like 20 years in parts and 10 years in labor, (their product was Carrier), so we thought maybe go with Sears! Then TDH Mechanical came, (Kris), looked at old HVAC system, and he just knew everything he was saying.

He told us a lot of similar things that Four seasons, and Sears told us, the he explained how the HVAC would be replaced. All the companies recommended us to replace everything since it's old. Kris explained to us that the air filter unit was still good. It didn't need to be replaced, but he can replace it if we like, ($400 additional), then he said that everything would be replaced except the air filter unit. Kris talked with Tim on what we needed, and he came back with a quote.

We went with TDH Mechanical because they replaced everything, (Furnace, coil, lines, condenser, humidifier and the only thing that wasn't replaced was the air filter unit), and the price was less than $5,500! The warranty was 12 years in parts and labor! They were able to install our new HVAC system in one day. Then there was a problem with our Ecobee4, (the mobo was bad, so we had to exchange it, but the Ecobee that we exchanged it for was the lower version. Kris told us to get the Ecobee4 or Nest 3rd Gen.), and Rolando was able to install the GoogleNest thermo with our new HVAC system.

We saved over half of what we were going to spend with TDH Mechanical. Thank you TDH Mechanical! Great job Jesus, Alfredo, Rolando, Jacqui and Kris. You have a GREAT TEAM TIM! If you need HVAC, air conditioner/condenser, furnace you should try these guys. I'm glad we waited, and got TDH Mechanical!

I was recently in the market for a new HVAC system and had obtained five quotes. Tim the owner of TDH was very friendly and gave me a detailed walk-thru of the quotes and installation process. TDH offered the best price which included a furnace that was a a more expensive model (variable speed vs single speed or two speed). I was able to schedule the installation on a day that worked best for my schedule and the installers arrived precisely on-time.

The AC condenser that I was quoted wasn't available at their supplier so TDH gave me a much upgraded model (higher seer rating) at no additional cost. The installers were friendly and did a great job of cleaning-up after the work was complete. TDH also had the best parts and labor warranty. I'll be recommending them to any friends and family that needs HVAC work.

This review is long overdue, but that is the nature of their work.the central air unit that they installed has been working so well that I never need to think about it. As for the customer service, first of all, I shopped around and they offered me the lowest price by far. I won't give the final price as I don't want to inflate expectations as I do believe my haggling abilities helped out.

Their service was excellent despite the low cost. I had an unit whose size was no longer manufactured, and due to a mistake by their equipment provider, they originally purchased a unit that could not fit into the closet space in my condo. As a result of me having to take a day off from work when they couldn't finish the job, they knocked off another $280 off the price!

They ended up needing to put the AC component on the roof, and they drilled a whole in my ceiling that has never leaked. Also, they honored the warranty with no questions asked and Chris came out twice to service the unit.the first time to fix a wiring issue and a second time which was really as a result of a heavy storm. Jim was courteous & accommodating on the phone on follow up calls. I highly recommend these guys!

Very smooth process. Called and emailed the owner Tim. He responded to my questions quickly. Talked me out of spending more money than needed. He did enough installation in the building (River North) that he just asked me to send the pictures. Mark and Jose came to installed it and got it done within a day. We found out we could not completely close the utility room door. They came back the next day and fixed it. Very professional. Good warranty too.

Professional service from initial contact to completion. I relayed the urgency of an inoperable furnace and was assured of prompt replacement. TDH met that assurance by advising then completing the installation successfully. I recommend their services to all with HVAC issues which require professional expertise.

Exceptional, they were amazingly responsive, it renews your faith in contractors. Very communicative, very professional from the office staff to the install team. They only deal in good quality units, not builder's grade, and back their service with guarantees. I'd highly recommend them to any home owner! Services: Heating system installation, Install AC

EXCELLENT! Wow- where do I start? If you're calling around and doing your research- look no further! TDH outperformed any HVAC company out there. Tim, the owner, responded within minutes. They are a no shenanigans company. I read other reviews and I did not get any bait and switch- all honesty and no BS. The crew showed up to do the install on time.

We hit a tiny snag because the pan was a little off, but when I texted Tim he responded immediately and his crew fixed it. The crew was fun- the guys played music during the installation but it was great- ya want to see your crew enjoying their work. Also- they were diligent about their cleanliness- making sure to ask me about shoe coverings and wall smudges.

They all wore masks. I appreciate the 12 year parts and labor warranty- their competitors did not offer anything close to that. The last part I should add is that I have bought a couple of HVAC units in my life. Even though I mentioned that I have another home in Florida and did not want my HVAC on WiFi- no one pressured me to buy more than I wanted. Don't hesitate to reach out to TDH- they beat Heatmasters, Shitvitz, Chicago Heating and Cooling. I will follow up with my review in 6 months.

Great company with whom to work. Guys showed up for a quote same day for our boiler replacement, were super thorough walking us through the process, and were great on price versus the 5 other quotes we had gotten. They showed up the next early morning ready to go and worked late into the evening to finish the install. For a job that required so much demo and cutting of pipe, etc they were unbelievably clean, like spotless.

They even cleaned up the mess the hot water heater install company had left. Now, we had an old boiler so we weren't expecting how nice of the unit they were going to put in. Their pipe work was fantastic, they put in a control panel, auto damper, and what we weren't expecting is they upgraded our original thermostats in each room from 1981 manual to modern digitalis thermostats. We weren't expecting such great work and attention to detail especially at this price-point, but these guys are great.

TDh is a very good company to work with. I initially talked to Tim the owner who was not only very passionate about his job he gave me a very fair quote. I'm moving into my new condominium and the HVAC system is very old. Khris came out yesterday to service, but after going over my options decided to replace. Today Khris and Jim worked very hard and diligent to get the job done.

When I came back to see the finished product I couldn't believe the difference. The passion in their job was next to none. I would recommend TDh for all my Hvac systems. Thank you again, Khris and Jim for a job well done. It was a 10 star job.

I don't know how other HVAC companies compete against TDH. Put in a top brand (Trane) 2 stage for the price others were quoting me for a mid brand one stage. The INstaller (Mark Keenan) found a world of hurt when they pulled the old unit out and craft a great fit on the spot (with a trip to the Home Depot). Instead of 5 hours it took 7 to finish the job, did not even ask if he could charge me more - which I would have understood.

We just had our HVAC system replaced by TDH = a/c and furnace. Tim was very kind and patient with me. Being this was my first go around with this type of project, I had a million questions and he answered them quickly and never made me feel like a bother. The units were installed in a timely and very clean manner. The installation crew kept me informed every step of the way. I would definitely recommend Tim and his team.

We received quotes on replacing our furnace and A/C. TDH was very competitive with pricing and offered a longer parts and labor policy than the others at no charge.
Tim explained why we needed certain features and not others. The guys who did the install did a great job. They covered all the floors with cloths and completely cleaned up before leaving. I highly recommend TDH.

TDH Mechanical team did a great job from quoting to installation of a bldg boiler in the middle of winter 1/24/19, They worked long hours to get the job done, restoring heat to the building apartments and keeping everyone warm. It was 15 degree high that day, they handled the installation and professionally, bleeding the system across all apartments to ensure everyone was in good shape before they called it a day late in the evening. Woitek the lead on the boiler replacement team and was great to work during the install and follow up process. Tim was informative in quoting the job, pointing out a vent issue on the hot water heaters which Woiteks guys took care of. Super happy to have worked with this team.

Just had new Goodman 5 ton AC unit and A coil installed by TDH Mechanical. I received their quote within 5 minutes from Tim after he evaluated my requirements. They offered a 12 yr warranty on all parts and labor including free Freon recharges whenever needed. Pricing was fair and towards the low end of the other quotes I received. Their expert crew (Rolando, Demitry, Alfredo) arrived on time and were able to easily handle re fabricating the sheet metal to adapt my old furnace to a considerably taller "A" coil.

This extra work maybe added 2 more hours to the install but in the end the price was still as quoted. They finished around 9:00 pm worked 6 Hours and never took a break. Every thing was cleaned up better than before they started.

Now that the fall/winter months are here, I scheduled my fall check up for the 2 furnaces at my home. Rolando came out to service the furnaces. He impressed me as being very thorough when cleaning the furnaces. He also changed the filter on the humidifier. After the job was complete he asked if I had any questions and was everything okay. I appreciated his attention to the job. Also, Rolando was being bothered by my lab "Bailey" while working on the furnaces but he never complained. He allowed Bailey to sit by him while he serviced the furnaces. Thank you for being patient and kind to my dog and for the great service call.

TDH Mechanical sent an experienced team to install our new central air system. Did a professional job in a few hours. Removed the old system and cleaned up after themselves. Knew I made a good choice when they came in with tarps and covered from my front door to the basement before they ever walked around. Would highly recommend them. Works great.
Jeff Sage
I had my furnace and A/C replaced. The owner was very straightforward, didn't try to oversell, and was responsive to all my questions. Larry did a great job on the work, staying late to make sure the job was done right instead of rushing through. Pricing was very fair and there weren't any additional fees despite them doing a few small additional repairs.
Ben McBurney
Just awesome. They guys were great. Shout out to Lewis and Rolando. Competitive pricing. Quick turn around. I have used them on multiple projects in the past and will use them again.

We've been very happy with all the sales and service reps we've worked with over the last 5 years. Tim and his crew stand behind the products and warranties they've sold us. They don't try to push service we don't need. The service reps are always on time, professional, cleanly, and kind.
Stephanie Riggs
We really appreciate the quick response and great service from TDH Mechanical. We woke up without heat in freezing temperatures, and Louis responded quickly and was onsite in a heartbeat! Great service, awesome communication about the issue / proper resolution, and extremely polite! THANK YOU!
Mary Diemer Nagle
Louis cleaned my furnace and I am very pleased I discovered this company. From the start when I scheduled the appointment to the end when the technician left I was impressed. He called ahead to let me know when to expect him. His curtesy and professionalism was much appreciated. He answered my questions and gave me a detailed list of the work completed. This will be my go to company for heating and AC maintenance in the future.

I was EXTREMELY pleased with the experience I had with Tim Hancz and his crew of men. Tim was a great guy to work with - very professional, not pushy, knowledgeable, and a man of his word. He told me I wouldn't be disappointed, and that I was in good hands. He was 100% right about that!! The guys that did the installation, Wojecht and Vlad, arrived right on time and worked two long full days.

They were polite and obviously knew what they were doing. They left my basement cleaner than it was when they arrived! They vacuumed the whole thing. All the debris from the old furnaces/air conditioners was picked up and hauled away on day two. Things are working like a charm, and I am cool as a cucumber! Nice work!!! I would definitely recommend them to friends and family.

I couldn't be happier with the TDH performance, price, and service. Everything was as expected. As a licensed home inspector, I know good work when I see it. And these guys did incredible work. Tim was wonderful to deal with as the owner, who came out and bid the job. And my installer, Kris and his partner Erwin were both extremely professional, and did a wonderful job. Couldn't be happier about my experience with TDH and would strongly recommend them.

I have hired TDH twice because they offer the two things that I value most: fair pricing and speedy service. Unlike other contractors, TDH gives you the best price from the get-go: no negotiating necessary. When I call, I get a call back within a few hours and even during busy times never more than 24 hours from my initial call. TDH is efficient, thorough, and responsive.

Another plus is that TDH will text and email as well as call to keep you in the loop of service appointments as well as to scan and send documents like proof of insurance. Overall, they are a solid company that I would gladly recommend to others and use again myself.
