I had some problems with bad parts in my system and TDH took care of it. Great responsiveness from the scheduler Jackie and great job by the technician Mark who diagnosed the issues and took care of the installation of the replacement parts. I would highly recommend them . I find customer service is not very good these days but TDH is definitely the exception.

I requested a quote for a furnace replacement and TDK responded quickly. They already had my info from 12 years ago when I purchased an AC unit from them. They gave me quotes for a single and double stage. Both had fair prices but I decided not to purchase from TDK because the person that came to give me the quote spent maybe 10 minutes here. He took a couple of measurments and didn't inquire to what I was looking for or even asked me one question. He didn't offer me any information about their products or even explain to me what the difference between the units are. So that left me to do all the work myself. That's the only reason I didn't purchase from TDK. I still have them 3 stars because of the past purchase and the quick response I received from the person who scheduled me.

Good luck getting in contact with them after the installation. I called them couple of times when the unit had issues and they never pick up or responsd to my messages. I had to pay another tech to come out. The 10 yr labor warranty is worthless just like this company.

We already knew the system was leaking, it was very old and needed replacement. Wally went through options and picked a system based on our feedback and home measurements. Quote was timely, apt was set up (non-emergency) within 5 days, even tho there were Tstorms and a heatwave. It was a tight fit, in an old house. All was done professionally. Price was better than most. Quality was also better than most. Very Happy with Wally and TDH

I'd like to thank you, Wally and Jesus, for replacing my old AC and furnace with new ones in my house! They did a great job. They have a great character as well: talk less and do more! Sincerely appreciate their help!!!

I previously utilized TDH's services for a prior condo I used to own when I needed my furnace replaced. Needless to say, I needed to utilize their services again to replace my furnace and central air for my current condo and was not disappointed. Because I had to travel out of State, they made an exception for me to install both on a Saturday at a specific time I needed to be present at the condo. They arrived on time, worked till mid-afternoon, and finished the job with no issues. The price I received was less than the competitors and their service is 5 star exceptional. I HIGHLY recommend TDH Mechanical and will definitely continue to utilize their services. Wally, Jacquie, and the rest of the team are amazing!!!

I called several times for 2 weeks, they never answer. To me is sounds suspicious. Are they avoiding their customers? Do they do jobs where their customers are not able to reach them if there is an issue?

I have a ten year warranty when my central air unit was put in back in September of 2015. It is August 18th of 2025 as of now. My compressor, capacitor, and an electric box went bad on my unit. We called, and a tech was out the next day, replaced all bad parts, with no charge. I will use this company for any HVAC work I need done in the future. Thank you guys. Mike.

Highly recommend Wally at TDH Mechanical. He installed a new AC and furnace after ours died and it was more reasonably priced than the other quote we received (by a lot). Wally took the time to explain the equipment and maintenance to me and was communicative throughout the process. Highly recommend.
