What Our Team Says About Chill Merchants
Trusted by tradespeople across South East Queensland for a reliable, professional and rewarding place to work.
“We had a fantastic experience working with Mark and the team at Chill Merchants.
They installed a large air con system in our workshop and office where several high temp machines run all day. These ducted units are big and heavy, and I wanted experienced tradesmen doing the job, and that's what we got.”
Matt Turkington

Communication was clear, site coordination was smooth, and their commitment to meeting program deadlines was evident throughout the build. Chill Merchants' professionalism and reliability contributed to a seamless delivery, and Bryant will actively seek their services for future projects.”

“Chill Merchants have completed a number of projects for us over the last 18 Months spanning minors works and duct work reconfiguration through to complete turn key commercial HVAC system installations.
Their communication, professionalism and trade knowledge is excellent. The transparency through the initial design and consultation process has helped to develop some great solutions to some very challenging problems. The installation team are extremely flexible, very thorough and produce high quality work. They turn up when they say they will and deal with onsite installation issues very quickly and with a minimum of fuss.
I would highly recommend Mark and the Chill Merchants Team to anyone.”
