“The entire experience with HarmonAire was excellent. From the initial proposal to the final installation, the process was seamless and highly professional. I particularly appreciated the flexibility in adjusting the installation dates to accommodate my schedule. Tom and his team did an outstanding job and the system is functioning perfectly.

Thank you again for the exceptional service and I would definitely recommend their services.“

“I had a great experience with Diego De Paz. He replaced my HVAC fan motor and fan, and the quality of his work really stood out. From the start, he was professional, knowledgeable, and took the time to explain exactly what was going on with my unit.

What I appreciated most was how thorough and careful he was. He didn’t just swap parts—he inspected everything, made sure all components were properly installed, and left the system running better than before. You can tell he takes pride in his work and doesn’t cut corners.

He also kept everything clean and organized while working, which is something a lot of people overlook. On top of that, he was honest about what needed to be done and didn’t try to upsell anything unnecessary.

Overall, excellent service, fair, and reliable. I would definitely recommend Diego De Paz to anyone needing HVAC work done. I’ll be requesting him again for any future repairs or maintenance“

“I have used a lot of different air conditioning companies over the years and by far, hands down, Cool Solutions is the best company I have ever dealt with. Jennifer is the best office manager and always tries to help out as much as possible. They installed an entire air conditioning system in my medical practice and not only did they do a fantastic, professional job at a reasonable price, installation was flawless and the system is working perfectly. From the owner to all of the staff, I highly recommend them and I would never use another company ever again. If you use another company I guarantee you will be making a mistake!“
