Walter & his team have great response time. Provided picture and explanation of issue. Resolved and had my A/C up and going immediately. Highly recommended if you care about high quality service. Thank you to Oscar & Walter.
Tony H.
Our AC went out Friday evening and repaired the very next day. Mr. Cool is Reliable, efficient, and professional. Walter and his team were able to replace broken Coil the same day. I highly recommend Mr. Cool.
Fabiola Ortiz.
I strongly recommend Mr. Cool for any AC or Heating problem you may have. Walter takes his business seriously. He's very profesional, honest and reliable. He has been working in my old York AC several times for the last 2-3 years until it made more financial sense to replace the whole system. You can tell customer satisfaction is the ir number one priority
