About TDi Services
Serving East Texas for over 60 years
TDi Services has been dedicated to serving East Texas for over six decades. In that time we have built a reputation for quality work and a customer-first way of doing business.
With that experience, clients know they can trust us to find the HVAC solution they need, whether it is a new installation or an efficient, effective AC repair. The same crews also work under our electrical and plumbing licences and install and service standby generators. You can trust that TDi Services is there for you, day or night.

Quality Since 1958 is lettered on every van.
The company many customers still call TDi Air Conditioning has that earlier name on the vans, on the crew’s shirts and hi-vis vests, and on the wall sign of the shop. Today the same fleet carries electricians, plumbers and generator crews as well as the air-conditioning techs.
At TDi Services, the customer comes first
For over 60 years we have worked to give the area the best service we can. We aren’t satisfied with “good” service. We strive to wow our clients during each and every interaction, and our technicians are prepared for most repairs when they get there, so we can finish more efficiently.
We take pride in being a small, family-owned operation that does business “the old-fashioned way,” and we’ve been rewarded by clients who have been loyal to TDi Services for decades. Clayton Whitney, whose home runs a system installed in 1962, is one of them.
