Comfort Systems USA Announces Internet and E-Commerce Initiative With Acquisition of Outbound Services.

HOUSTON--(BUSINESS WIRE)--Nov. 3, 1999--

Comfort Systems USA, Inc. (NYSE: FIX), announced today the acquisition of Outbound Services, an Internet-based technology platform and call center designed to manage the heating ventilation and air conditioning-related services and information needs of multi-location customers. Outbound Services was a subsidiary of Tanknology-NDE International, Inc. (Nasdaq: TNDE). Terms of the transaction were not disclosed.

"Outbound Services is one of the most significant strategic acquisitions Comfort Systems USA has completed to date and brings us an Internet and e- commerce platform with value added services that we need to more effectively serve national accounts," commented Fred Ferreira, Chairman and Chief Executive Officer of Comfort Systems USA.

Through the acquisition of Outbound Services, Comfort Systems USA is well-positioned to offer expanded, turnkey service capabilities including:

- Real-time Internet access on the status of service activities.

- An Internet portal providing a powerful data warehouse of

information on equipment, energy and facility costs.

- One verified bill encompassing all building locations.

- E-commerce capability for both customer interface and Comfort

network operations including service delivery and procurement.

- An 800 number providing a single point of contact for

multi-location customers.

- Trained operators capable of troubleshooting and dispatching

service personnel nationwide 24 hours a day, seven days a week.

- One-stop shopping and a consistent level of service.

Gary Hess, Comfort Systems USA's Chief Operating Officer, added, "The acquisition of Outbound Services provides our national network of companies with leading edge, web-based customer service and support. By delivering a comprehensive system including a call center and Internet accessible invoice, data and management services, we are directly responding to the needs and requests of the multi-location property owners."

Mr. Ferreira continued, "Outbound's Internet and e-commerce capabilities are an important investment for Comfort Systems USA as we expand our leadership in serving regional and national accounts. We expect this investment will have a dilutive effect on earnings per share of approximately $0.03 in the fourth quarter and approximately $0.03 in the first half of 2000 as we integrate Outbound with our service network, although we expect the full year impact for 2000 to be neutral. With our investment in Outbound, we expect to see exciting progress in our multi-location strategy in 2000."

Jim Law, President of Outbound Services, added, "Joining forces with Comfort Systems USA presents Outbound Services with a tremendous opportunity to respond to the growing demand of multi-location accounts for a seamless, single-source, e-commerce solution. Outbound's strong, Internet-based systems and service management experience enables Comfort Systems to further capitalize on its national network of companies and meet the needs of current and potential customers."
