Excellent, Timely, and Professional
I highly recommend TDH Mechanical to anyone in need of HVAC work. Totally hassle free from the time I reached out to them with my issue until the service call completed. Rolando was very polite and professional and met the time-line he committed to.
Soji - South Elgin, IL 60177
Excellent Service!
Super fast and professional. My furnace went out unexpectedly and they came out to install 7AM next day. They were not the cheapest we found but we are big on quality and customer service. So, we went with them.
