This letter is to thank Custom Air Products for the hard work they gave Magellan for PM’s and new installation. You can count of them to do the job accurately and with the customer service to make sure the job is done right. I would refer CAPS to any company thinking of new installation, troubleshooting and preventative maintenance.

Dan LawsonSupervisorGalena Park, TexasMagellan Midstream Partners

We have been working closely with CAPS on a lot of projects, and I have been to their facility a number of times now. They have a first class operation, testing capability, training, and extensive engineering expertise with custom HVAC applications. I would highly recommend using them if you ever need help. They have exceeded all our expectations for a vendor, and been a tremendous help to us on solving these Middle East problems. I can’t say enough about how easy they are to work with. Based on the way they have stepped up for us and the high quality of their products, we’re working on integrating their wall mount units into the next fleet of Ideal Rigs, as well as other systems.
