Custom Air Products & Services, Inc. (CAPS) is the largest manufacturer of custom heating, ventilation, and air-conditioning (HVAC) in North America. The company designs, builds, installs and services HVAC systems for a wide range of industries.

CAPS is comprised of three divisions which encompass design, manufacturing and service of commercial HVAC systems. Their team of experts can service any make or model of industrial HVAC equipment, whether serving as a portable or permanent installation.

Custom Air Products & Services, Inc. is a full service company specializing in the design, execution, installation, modification and servicing of industrial and commercial air conditioning equipment. From its headquarters in South Houston, CAPS serves a diverse group of clients from four major service areas.

Four service markets

  • Offshore/ marine drilling
  • Chemical and petrochemical plants
  • Healthcare and medical
  • Retail


Dave Wasson, vice president of service for CAPS, oversees a skilled and highly trained workforce of 100 employees. The CAPS mobile fleet is on the road 365 days a year, 24 hours a day, serving clients with preventative maintenance and on demand service calls.

Commerical and Industrial Service Areas

  • Demand and emergency repair
  • Maintenance and preventative service for heating and HVAC units
  • Replacement and retrofit for small and large units

“We invest heavily in training for our HVAC service techs,” said Wasson. “It is our goal to empower our employees and establish long-term relationships with our clients. We provide them the highest standard of service and preventative maintenance. If we can catch a $50 problem before it escalates to a $5,000 expense, we know we are on the right track.”

Purchase of a custom HVAC system can be one of the largest capital expenses for any company. That is why Wasson and his team place such a high priority on meeting every need and focusing on energy efficiency. Once a company chooses CAPS for the design and production of their HVAC unit, a long term relationship ensues and continues for many years.

“We are proud to serve a diverse group of clients in public and private firms and continue long term trusting relationships,” states Wasson. “Despite the current downturn in the economy, we are retaining customers by helping our customers extend the life of their equipment and lower their utility bills.”

Custom Air Products is proud to carry a full line of air handling equipment and commercial HVAC units. Commercial and industrial clients are invited to tour the CAPS campus and be part of the design and production of their air conditioning and heating equipment.
