Excellent service, great price, very pleased!

After many estimates , TDH had the best price no bells and whistles we didn’t need. Explained everything in detail. Arrived on time. Did beautiful work. I am very pleased with the job results. They also have a great warranty! I’m only sorry I didn’t think to have my hot water tank replaced at the same time.

TDH installed a new boiler recently. Everything about the process was excellent. Wally and Jesus were top notch. Not only did they do exceptional work but they way they installed all the pipe work is a work of art … truely beautiful! I will highly recommend TDH to friends and use them on other projects.

Easy Scheduling + Install

I got a referral from a neighbor who replaced their HVAC system with TDH and went with them over two other contractors, as they provided a better quality unit in the spec and at a better price. The installation went quickly, and the new system is a huge upgrade from my 17+ year old one.

Excellent

TDH quoted us for a new AC and furnace after ours died during a hot spell. They were priced better than the other quote we received and their team installed everything with respect and efficiency. I am grateful that Wally the technician took time to communicate with me throughout the day and explained the parts, the mechanics and maintenance going forward. Highly recommend.

Our installation team of Wally and Chuy were wonderful. They had our furnace and A/C installation completed in amazing time. Very informative as I asked questions (I tried to get out of their way!) we are more than pleased with the TDH team. Thank you
