Report
We contacted TDH for a malfunctioning A/C. We received outstanding professional service from both Louis and Rolando. (The second visit was required to replace the TDX after ordering.) They were both very patient and courteous in explaining the issue and answering all our questions, and they covered everything under warranty with no effort from us.

They called a few hours before and asked to come earlier than expected which was great because no ac with a newborn isn't fun. Everyone I worked with was professional and respectful. I would recommend them to all my friends and family. They were very helpful. Thank you!

Had a great experience. The Installers did an awesome job. Very courteous and professional. I would definately recommend them to family and friends. The pricing was $1000.00 plus under all our other estimates. The work was done in a timely and professional manner with minimal mess. Thank you Home Advisor for recommending them.
