TDH Mechanical has provided the best quality service for years to my household. Tim Hancz started off our account and they have been fantastic. Good consultation. Products have performed well. I suggest getting the yearly cleanings. Always responsive and prompt when servicing. We purchased furnace and air conditioning. 14 years ago and they've been great. They key to home ownership maintenance is finding great vendors you can depend on. Thanks TDH! read more

While inspecting the excessive noise from the furnace they installed, their technician discovered that their installers had left a melted screwdriver (see attached photo) inside the unit during the original installation. The tech that came out to fix my furnace - again because it was making a loud noise - simply put a long green metal pole jammed up against the chimney to dampen the noise(see attached photo). That was his solution ha. Then they paired the new AC with an undersized return, so it can't move enough air. The evaporator freezes with any normal air filter, and the only way to keep it running is by using the cheapest, least restrictive filter possible thus compromising air quality. And then in that same newly installed AC system the foil-faced insulation inside the air handler came unglued and detached, falling against the evaporator coil and restricting airflow. Absolute F tier quality work. Surprised they're still in business. They're impossible to get ahold of; techs that do show up are overworked and don't give a crap. All of these problems still exist to this day and everything is still under warranty but tired of them coming to my house and half fixing the problem only to call them again and again. All in this cost me about $12,000. Avoid at all costs. Good luck. read more

Great service ! Had a warranty issue and they handled it no questions asked and quickly read more

Called TDH several years ago to replace my AC unit. Price seemed reasonable and Tim was very helpful when talking to him about the process. They replaced my AC unit and reworked some of the ductwork as well. Their technician left and I noticed that the air coming out of the vents in the house was not cool. I called them immediately and the technician came back and recharged the new unit. It still was not blowing cold air but they said it should get better. It's been years now and the unit still does not blow cold air. I've called them every year to come out and no one ever seems to be able to fix it. I've changed fans, insulation etc. at their direction and still does not work properly. I've tried contacting Tim over the years and he never calls back. For me this was a complete waste of over $6k since I have no choice but to now purchase a new unit since they have never fixed it! I know others have had a good experience with this company but for me it has been a nightmare. If everything goes fine you're good, if not, they are not going to make it right so buyer beware. read more

Had my furnace and AC replaced 9/25/23 by TDH. Two guys replaced a 70 year old cast iron furnace and installed new Ac system in a day. Great experience, the work was done very professionally and without any hitches. If this is typical of work done by this company, I would highly recommend them. read more

For years our commercial HVAC units have been broken, and TDH has been more than patient with us, on-site visits to help rectify what they could on a weekly basis until we were able to make the move and replace both roof units. Galacio, Ronaldo, Bernie, Emily, Jackie, and of course Tim are a pleasure to work with. When it came to for the big install, not only were the logistics handled incredibly fast but TDH accommodated a difficult request from our neighbors to start the on-site work prior to 6am on the Saturday of 4th of July weekend. Everyone on the team that day was an all-star, I really can't praise them enough for how unbelievably precise and coordinated they were. Their constant communication, attention to detail, and honesty is unmatched to any other service I have worked with, I wish everyone was as fantastic as TDH. read more

The service, price, and professionalism was excellent. I purchased HVAC, humidifier attached to the furnace and Ecobee thermostat, July, 2023. Called on Monday for quote and installation, and was scheduled for installation two days later. All installed in one day. They removed/ installed everything. They arrived @ 7:30a and finished @ 5:30p. Showed me how everything worked, and the company called me the next day to follow up on the service. Love that. I had checked around to various HVAC companies and their prices were not competitive. Some just wanted $10K.. just for the A/C. I would highly recommend them for price and service.. LA read more

Wonderful business! My heat went out on December 23. A commercial chain on the radio came in and said I needed a new furnace and quoted me 8,000$. In a sheer panic I called TDH. I spoke to Tim who calmed my panic, provided a quote through pictures, explained the different options available. He told me this installers would be there at 7 am and at 6:58 they were there! They installed the furnace, hauled away the old furnace, and made sure the new furnace was , made sure working perfectly. All this on Christmas Eve. The cost? Less then 5k! I will definitely be contacting them about installing new central air this spring. Support small business you will be happy you did!! read more

TDH Mechanical has done an exceptional job installing our new furnace and have hired them for other maintenance work which was also done on time. The staff is very experienced and polite. read more

My grandmother used this company for both her AC and Furnace installation. Both have not worked properly since she's had them. After many Maintenence check ups, this company said that everything was fine. However, neither the AC nor Heat functioned properly. Finally we had another company come inspect both and they said that the AC and Furnace were not installed properly. This has created a lot of damage and very expensive repairs. My grandmother has called this company MULTIPLE times and sent many messages and no one has responded to her. This company should be ashamed of themselves for taking advantage of an elderly woman. Have the decency to return her phone calls at the very least. We have over 90 photos of proof of the improper installation. read more

I had my AC serviced today. Fortunately, everything was covered under warranty. It took over 24 hours to get a call back from the company and my husband was given a window time from 7AM to 11AM for the technician's arrival. I tried calling when he still wasn't there by 10:30 AM as I had to go to work. I couldn't reach anyone. You always get a message saying they are "away from their desk." When the technician arrived at 10:55 AM I asked about the window of time given and was told "we don't do service calls at 7AM." I would have appreciated knowing that as it's my late night at work. I also would have appreciated a text or phone call with and ETA. Overall, the repair went smoothly and was covered, but I gave the company 3 stars due to communication concerns. read more

I just had an AC/Furnace combo installed a few days ago and the entire experience was great. I am really happy with my new Trane products. I am still trying to get used to the smart thermostat they installed and woke up the other morning with 58 degrees and freezing in my house : ) I didn't have any problems with my previous units however they were very old and trying to be proactive and replace them before I did have a problem. I didn't realize how inadequate both were functioning until I got the new units. read more

I have a mixed review. The good -- They came quickly, they installed a new AC for us at a price that was half of what other contractors quoted, they consistently respond to questions. The frustrating -- the new AC they installed fit poorly in the ceiling, leaked water at first, and necessitated follow-up work and installation of a new pump. Also, because the AC does not fit well in the ceiling, it may be challenging to maintain in the future. read more

Exceptional service from Tim, Bernie and crew. They installed two full Trane HVAC systems and condensers with smart thermostats in one day, including redoing all the poorly designed venting and other issues with the system we inherited with the house. Very organized and professional at a great value for the price. Biggest tip I ever gave I was so happy with their work. read more

TDH Mechanical, Heating and Cooling Contractors - Beautiful, clean install. - Heating & Air Conditioning/HVAC Near Me - Chicago, Illinois

This is an A++++++ company, from my first interaction to getting a quote. They replaced my Furnace and AC. Installed Carrier unit. Very Professional and very fair price. Mark & Videl came to do the install right on time. And stayed until the job was done. Very neat and respectful of my home. You won't find a better company then these guys. You can't go wrong. Family owned. Great Ratings read more

I took about a dozen bids for a relatively challenging HVAC replacement project at my River North loft (gas furnace is located above my bathroom ceiling, in a tight space; hard-to-access humidifier; plus an AC unit up on the roof). Not only did TDH offer the most competitive price on top-rated Trane equipment, they were fast to respond, and had everything installed and running within a few days of my first call. Actual equipment install took one day. Every person I worked with at TDH was professional, courteous, and quick to respond. The installation crew stayed behind to clean up afterwards, and they called me the following day to make sure everything was running correctly. I could not be any more impressed with TDH Mechanical, and I would highly recommend them. THANK YOU, TDH MECHANICAL!! read more

We selected TDH Mechanical for our Multi-Unit Apartment Building in Aurora,IL after careful and methodical evaluation of 6 other Boiler HVAC Experts. Each of them evaluated our situation in detail just as TDH Mechanical did and proposed a solution/price. We selected TDH Mechanical for many reasons, and wanted to share with you in this open feedback/review forum. And yes, we read all of the reviews / feedback from all sources, and of course, and TDH Mechanical has a huge list of happy and satisfied customers, and here we are adding one strong one to his huge list. Based on our detailed set of questions regarding the installation, Tim personally got the Boiler installation expert to visit the site to answer all our specific questions, pipe-replacement-detail and that discussion instilled huge amount of confidence in us. Tim, also allowed us to clarify some of the matters via email to ensure full clarity of the proposed Boiler solution. We had a huge variation of answers from various HVAC experts including some out of the box, and completely out of bounds in terms of prices. Tim's team kept is simple, relevant, and proposed the best and most simplistic answer that would meet our specific requirements. Tim's style of management is instilled in his people from a work ethic, honesty & integrity, exact date of start as promised, timely show at the job site, no waste of time during the work-day, and timely finish without rushing. Post,Covid in 11/2022, it is rare to find these ethics in companies especially for a job of this size. The simple high confidence message and low tone that Tim portrayed on the phone, without any pressure to make decision made this a Win-Win for us. His team did an absolute perfect job with the Boiler installation, with no compromises, or short-cuts, relayed all the instructions required for on-going maintenance, and put in the best value-based-competitive solution (not the lowest price), with a perfect show of customizing to our specific requirements. Our completely independent with no relations with anyone at TDH until this transaction, we can clearly say that TDH Mechanical wins our hearts and made us a referencable customer for life with this 1st job that we gave him, there will be many more to follow. read more

Very responsive with very competitive pricing. Our furnace went out beginning of Feb and Tim had his crew out ASAP to replace our whole HVAC. The installation crew was great and everything is working well. They also worked with me on my home warranty claim, which was a lot of phone tag! I highly recommend them. read more

The installers were punctual and put tarps down so the floor didn't get dirty. They installed a Trans furnace. The price of the furnace was substantially lower in price than competition. Would definitely recommend them to anyone needing a new furnace. read more

They are the most reliable and fantastic company to work with. Starting with Tim helping with estimates and Mark/Alfonso coming over to install my water heater. They also tuned up my furnace and did a duct cleaning. They had to move my washing machine out of the way and went above and beyond anything I could ask for. The pricing is fair and couldn't ask for better service all around. I will always use them for anything I can read more

I'm quite satisfied with Tim and his team @ TDH. Estimated Cost to install a new Heating and AC condensing unit was pretty good and decided to hire them out of 5 companies I met. Their team is impressive from the start. Got the job all done within a day after contract agreement. They respond quickly when i have questions with regards to project cost all the way to completion and local permitting. Will recommend them based on work they did for me 2 weeks ago. Good Job Team TDH ! Keep it up. Thanks! Rhomes read more

"TDH Mechanical" isn't a name that stirs much emotion, but the quality of their service sure does. Replacing my HVAC unit wasn't an experience or an expense I was looking forward to, but THD sent out two wonderful gentlemen who not only installed the unit beautifully, but were also friendly, honest, and respectful in every single way. Their price was right in line with the lowest of the other quotes I received, and it was for a top of the line brand. I don't know how I know "TDH" stands for "Totally Definitely H-awesome"...I just know it's true. read more

TDH took good care of us. They installed new zone valves and a new panel. It was an expensive project but they were very competent and the end result is perfect. Dimitri did the work in our house. He is a really good guy and very knowledgeable. I would go back to TDH if we have any future problems with our boiler. read more

In January 20 year old heater stopped working. Called TDH who sent someone to look and do a quote. They gave clear quote for a new forced air heater and AC at same time (which was also 20 years old). They got a crew in within a day or two to do the work. All as planned, and I did some research in the mean time to see the price was right in line. Heater works well since then. read more

Very thankful for efficient, friendly service. Ken came to clean our air conditioner and found it to be in good condition. About a week or so later it stopped working. We called TDH and they sent a repairman the next day to check it out. Turns out we had trouble with our furnace (not at all related to the service we had a week prior). Thankfully they were able to fix the problem quickly and our house is cool again. Thank you, TDH! read more

If you want your time wasted, inept communication, and for the owner to get very personal and call you a name, then this is your place. Nothing but confusing information all around. I first couldn't even get a hold of them by phone. I kept leaving voicemails and eventually they were not returned. So I turned to email and started to get somewhere. I was offered an initial day, then it was revoked by the owner because being X (insert negative adjective) does not get you an appointment sooner. Ultimately I was going to take it, but told him I was not available during that time, which he just repeated what he initially said "Thursday 8-2". I began to wonder if this was a joke.... I was asking questions about the cost of the service because my AC is under warranty (previous owner's choice--not mine), but could not get a straight answer. This is just business. It is not personal. It should not even be hard. Not recommended. Use Abt instead. read more

My furnace died a week after buying my condo (on a Saturday night in the winter). After having a different company come and give me very high quotes for repairs & a new furnace, that would also take days to schedule, I found TDH. I spoke with Tim who was able to give me a much more reasonable quote and schedule service for 7:30 the very next morning. The two technicians who came out were also really friendly, courteous and helpful. As a first time homebuyer, they made sure I knew about my filters, registering the new furnace for the warranty, etc. I will definitely use TDH for future servicing of my heat & AC. read more

These guys are the best and really know there stuff. They put in AC and attic fans on our 170 year old house, which took some major engineering. We couldn't be happier. Thanks to Mark & Jesus for all their hard work. read more

I had a problem with my air conditioning unit and called TDH. They came out quickly and said it was a clearing of the lines and a filter change. Charged me $200. However problem still persisted and when asking for a quote to replace the whole thing, I tried to track the quote.down for nearly two weeks but to no avail. Kept getting empty promises that they were waiting on the supplier or I would get it within a day. I wouldn't recommend you go with them. read more

New Power Vented Water Heater & Gas Steam Boiler installed October, 2020. 1.QUOTES - were detailed & quickly executed once approval was granted. 2. INSTALLATIONS - Exceeded expectations. Techs were on time, install duration was within the specified time period. Some clean-up was missed after opening brick to create a pass-through for the water heater power vent but was quickly addressed when pointed out. Overall their step-by-step methodology and technician skill-sets were exceptional. 3. GAS WATER HEATER - works great with plenty of hot water at all times. Product is Pheem 75 gallon with power venting 4. GAS BOILER - has been a source of frustration due to an intermittent issue where it doesn't fire. Product is a Dunkirk PSB-8 5. CUSTOMER SUPPORT - Meets expectations. Once you sign a contract, TDH will email your user ID and link to their Service Portal for use when requesting service appointments. Luv it! IN SUMMARY - I am pleased with the overall TDH experience and look forward to successful troubleshooting and resolution of the intermittent Boiler issue (ie.. low water cutoff probe, wiring, piping or other). Once the issue is resolved, I will update this post. read more

Contacted three firms in the Chicagoland area about replacing a noisy furnace on our second floor. Tim from TDH responded nearly instantly and had a rep out the next day to make recommendations. TDH's pricing was competitive with the other two bids we received and their thoughts on additional ways we could lower noise levels were appreciated. On the install day, the crew was efficient and amicable. The work performed was as described and on budget. After the install, we found that our system needed an additional relay installed between the humidifier unit and our thermostat. TDH offered to come out and install the necessary relay at no additional charge. We're enjoying the much more quiet furnace and feel confident in TDH's work and customer support in the future. read more

I called TDH today (Sat 2/15) to fix the furnace which was blowing cold air. They were responsive and professional and we came out in a couple of hours. They charged $95 to come out. They replaced a sensor and charged me an extra $195 for parts. The only issue is that sensor cost $25!?! I called them on it and gave them a chance to apologize and not price gouge. Their response: it's the same $25 sensor but ours has a 1yr warranty....Gimme a break!?! THIS IS ABSOLUTELY UNACCEPTABLE!!! TDH just lost any future business and sure will NOT recommend them to anyone. read more

TDH Mechanical, Heating and Cooling Contractors - Old flame sensor they replaced and charged $195 for it (costs $25) - Heating & Air Conditioning/HVAC Near Me - Chicago, Illinois

This is my 2nd time using TDH for furnace/ AC unit issues over the past year and a half or so. Technicians have been great and got the job done. This last time the technician was, however, 35mins late to my 4 hour window. No apology of any kind was given, just stated previous jobs as reason for being late. Would have loved some sort of compensation for them being late since it then threw off the rest of my day. $125 just for them to come out to 'diagnose' the issue (none of that is then applied to any services rendered). $145 "labor" charged to recharge my refrigerant in AC unit. $65/ lb of coolant added. read more

This review is about buying a new HVAC unit (furnace and AC). I shopped around a year before buying and TDH would went through each competitor quote with me and worked to get close to price and quality. Their technicians were nice and went through proper maintenance. This was my first experience buying a HVAC system for my house. Kristin the office was friendly and prompt via email and when it came time to purchase, the owner Tim called me and went through everything. They came two days later with a big crew that was friendly and quick. They make sure you register your products online and keep up on how to keep your system running. TDH was one the few companies that was straight to the point with what was wrong with the old equipment and what would be best for the house. I looked at Costco, Home Depot, ARS...etc....TDH was by far the best less hassle experience. There were cheaper prices out there, but not by much and not with the reviews and support I felt I received with TDH. It's worth giving them a call and if you need escalation, the owner does pick up the phone to push things through (thanks Tim) read more

I had a Trane Furnance and Air Conditioner installed yesterday and the experience went off without a hitch from start to finish. Everything was perfect. Rolando and Jose A. were professional and detailed. Because my previous furnance was 47 years old and was in a tight closet I think they had to deal with an extra challenge but they handled everything beautifully. They even had to create something out of sheet metal and it turned out great. They worked so hard but never a word of complaint. I can't think of one suggestion. Then this morning I called to register the serial numbers and the young lady I spoke with couldn't have been more helpful. Whoever is in charge of hiring your personnel is doing an excellent job. Your staff is marvelous. I couldn't be more satisfied. You may give out my contact information if anyone asks for a reference. read more

I am recommending TDH Mechanical to anyone who requires new HVAC equipment or to anyone who requires repair of existing equipment. TDH installed a new furnace and new AC system in my four story townhome last summer. The owner, Tim, did not play games with pricing (I had four other bids as well) and he educated me on the equipment selection. The price for equipment and installation was fair and the service team was professional and TDH did the job right. Well, almost a year later, I had a minor issue that needed to be resolved. My system needed a fast-stat, to allow for a deficiency with a Nest thermostat, as I also had a humidifier and we were one wire short. Louis, a TDH team member, came out today and installed the fast-stat, after he walked me through the different options, and we agreed on which was best for my circumstances. Louis was great - fast, professional and willing to answer all my questions. Great job by TDH from start to finish. Thanks so much for the outstanding customer service. TDH is the way to go! read more

I couldn't have been more satisfied with TDH. Ken came out and diagnosed the problem I was having with my 20yr old furnace, despite it being shoehorned into a small enclosed closet half way up my wall. I was given multiple repair and replacement options in the quote. I ended up doing a full replacement as I was tired of dumping $$ into this 20yr old system. The installers clocked in at 7am (on time!!!) and didn't leave till almost 9pm, they wouldn't leave until the job was done. (in my building this is how long it takes to replace everything, we are all starting to replace our old HVAC systems). All Covid protocols were followed, they cleaned up after themselves, I could not have asked for better service. The communication was stellar. Ken showed up on time to diagnose the problem, had the quotes with options within a few hours, and scheduled that night. I had a call the day before the install just to confirm that the new system is in stock and ready to go and to confirm the 7am start time. I had some additional questions and Jim was my goto for an issues that came up or questions I had. A+ read more

Ok. I'm going to be fair and say that Ken accurately diagnosed and fixed my problem with my furnace. My concern is that I feel I was overcharged. I was charged $190 for 15 minutes of labor. That doesn't seem fair. When Ken came out and diagnosed the problem and told me the cost of the labor I thought it was pricey but I figured that it would be an hour or more job. To my surprise it took him about 15 minutes to finish the labor. When I was about to pay I asked him how much they charge per hour and he never really answered that question but just stated that the 190 was for them retrieving the parts as well as the service (FYI the parts were under warranty so they were free). I still think this is a bit pricey. While the service was sufficient ( heat is back pumping), I would not use this company again because I feel that I have been gouged. Other companies I have used in the past pro-rated the amount if it wasn't the full hour of labor and this wasn't even half an hour. And honestly even if the labor was a full hour I still think 190 is a bit pricey. Amendment: Today I spoke with the owner, Tim. He took his time and explained to me that Ken had to drive an hour each way to retrieve the part from one of the only vendors who had the part in the city. With that being saiid the cost makes much more sense and I am a bit more understanding about the price point. Heat is working great as well. read more
