We are a family-owned and operated company offering 3 decades of experience that is dedicated to providing an enjoyable service experience for you.

We love what we do, we take our job personally. Each person on our staff of 8 is handpicked by owner Tim Hancz. All of our work is done by our staff, we do not subcontract work to 3rd parties.

Sometimes heating and cooling issues are straight forward, and sometimes they are the only the tip of the iceberg. We always prepare the immediate and obvious problem, but always carefully look at all parts of your system. This will be our approach on sales or service calls.

Repair

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.

  • Top tier brands; Unbelievable good prices! The installer was amazing making it all work small space
  • None yet. Let's see how service goes. Expect it will be as good as the install

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.

Customer Testimonials

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.


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 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.


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.


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!


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.


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.


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.

Air quality is one of the factors of indoor living that can't be taken lightly. Even if you leave your home for 12 hours a day with work and other activities, that means you're still inside for the remaining 12 hours, breathing in whatever happens to be in the air. Airborne contaminants can range from simple dust and dirt particles, to mold and algae. If people inside your home have allergies or respiratory issues, cleaning up the air will help. Some estimates say that an average family can produce up to 40 lbs of dust in a single year.

We will send a cooling specialist to your home to get to the bottom of the issue and offer a practical solution. During an Illinois summer heatwave, the hot air gets trapped inside your home, and unless you have an effective air conditioning system, it isn't leaving. Even at night with the windows open, the heat can be unbearable. If there is no breeze to offer any relief, you'll be doing more sweating than sleeping.
