Awesome experience . I’ve had multiple contractors at my home over the past year that were never on time always left a mess in and outside of my place . Koalafied was here early , Corey and his team were super respectful and informative . They cleaned up after the job . And delivered quality work . I would recommend them to anyone.

Above and beyond doesn’t even describe the service Fred gave! He was friendly & professional. He had to make 2 trips due to not having the part but he understood my concern with the 90 degree heat & my family. He made sure everything worked and cleaned up after himself.

On 6/24/2023 Rachel S. had this to say:
Look no further - Koalafied heating and air is WONDERFUL and HIGHLY RECOMMENDED! Their knowledge, customer centered focus, and overall approach to helping customers solve problems and getting the job done right is unmatched. I manage properties coast to coast and Koalafied is head and shoulders above their competition and will always be my first call for any and all HVAC needs in the Kane County and DuPage areas.

On 6/8/2023 Erika Salemi had this to say:
Fred came out and did more searching and asked more questions than anyone ever has! He definitely knows his trade. We won't be calling anyone else from now on! He was also so polite and kind!

On 6/2/2023 Linda Lee-Saflarski had this to say:
Efficient and professional repair of our AC system when we needed it most! Koalafied communicated quickly and clearly with our home warranty company, and for us, the entire repair was covered. It's important to understand your home warranty coverage! We won't hesitate to call on Koalafied for service in the future. Great job, Cory! Thanks again
