"I own a laundry and needed two new swamp coolers. I called DNA and Andrew came out and from our first meeting was very professional. He was knowledgeable and able to answer all my questions which put me at ease. These guys did a bang up job. They were clean and made short work of removing my old units and installing of the new ones. I would highly recommend DNA for future work."

"Service was great and pricing very competitive. Nick Knuth was very knowledgeable when he came to do an assessment of the work to be done, and answered all my questions I'm a very clear way. The techs worked pretty quickly and efficiently when installing the new unit. Deisy and Emma from the office always made sure that things were taken care of and went above and beyond with follow-ups and updates. I would definitely recommend them to anyone who needs this service."

"Guil's assistants installed the air conditioner in the window on Monday, June 6th, and did a good job, cleaning the window and removing the old AC. Guil came the next day and took away the old AC and caulked up the gaps in the seal on the new AC with his caulking gun. Guil was very courteous and upbeat about the install. We hope to use him again on a future project."

"Mr. Avery called me and knew what I needed. He came out and was here in 15 Minutes. Mr. Avery was happy to give a free estimate, when everyone else that contacted me was not. Most others wanted a minimum of $80. to $90. Mr. Avery made a call to his Business and made sure they had the Part in stock that I needed. When he returned, the part was installed within an hour. He stayed to make sure that everything was safe and worked as intended. He was very professional and had a good sense of humor. I recommend 'Just Be Cool Supply' to anyone who needs Furnace repair. Mr. Avery is a Licensed Professional and the price was very fair. I will call them again if needed. Thank you Mr. Avery."
