CT/HX - A Fidelity Company

CT/HX operates from Hanover, Maryland, as part of the Fidelity Building Services Group. The company maintains standard weekday hours from 9 AM to 5 PM, closed weekends, and can be reached at (800) 377-1883. With a rating of 4.2 stars from five reviews, they focus exclusively on commercial and industrial cooling tower systems and heat exchangers rather than residential HVAC work. Their service menu includes refurbishment, repairs, OEM parts, and performance testing for customers managing large-scale mechanical infrastructure.

What distinguishes CT/HX is their depth of specialization in a narrow mechanical niche. They handle all brands, makes, and models of cooling towers, offering single-source responsibility for parts, accessories, and full refurbishment projects. Their service portfolio spans structural repairs, heat transfer media replacement, mechanical powertrain upgrades, and sump coatings. They also provide safety platform installations compliant with OSHA requirements and perform expert sound, vibration, and performance testing to optimize equipment efficiency and extend operational life.

A recent reviewer documented an unsettling encounter on a Richmond-area highway, describing aggressive driving by a company vehicle operator and multiple unsuccessful attempts to reach management about the incident. This review noted that despite leaving contact information with two receptionists, no return call was received. The complaint was escalated to both local authorities and the Better Business Bureau. While this represents a single data point from the available reviews, prospective commercial clients may want to consider how such driver conduct could reflect on their broader organizational culture and customer service practices.
