Client Reviews
Thank you for supporting a local, family-owned business.
We truly appreciate your time and trust!

Carlos is just a call away. I called him on 4/20/2023 at 6 p.m. Said he would come over around 1 p.m. the next day. He showed up at 10 a.m. Turned out it was nothing serious thank god but he took care of the problem right away. His work is exemplary and his prices are fair. He is a great trustworthy gentleman. We will remain loyal customers.

I have been using Cool-Aid for a number of years. Carlos and his team are very professional and truly responsive. I know I can count on this team of professionals when I have a cooling or heating problem. Unlike other companies, they are honest and play no games. Their integrity is unlike any other. During this time of high inflation, they still maintain very reasonable pricing. I used them again this morning to replace a bad handler motor. Again, very responsive by being here quite early, job completed professionally and at an amazingly reasonable price. Thank you Carlos. God bless you and your team.
~ Arnoldo Rodriguez

Carlos came on a Friday, gave us a quote and said he could install the next day. Arrived on the scheduled time and 45 minutes later we had A/C, for the quoted price. I had some other people do some work for us and the final price was well above the quoted price. Carlos was fantastic, honest and very professional. I highly recommend him for all you A/C needs.
