I've been looking to replace my previous A/C repair company who sold their business; Service First is absolutely outstanding! Joseph was my maintenance technician! He explained everything that he performed, explained ways to make my units last longer, and was highly professional. He went above and beyond all of my expectations! Joseph has 18 years of experience and it shows! And, the prices were very reasonable. If you are searching for a new A/C repair and maintenance company, I give my highest recommendation to Service First Air Conditioning! Also, recommend considering their service plan to further save money!

Service contract is a scam. Won’t let you book at any convenient times, only on their limited time schedule and will charge you a cancelation fee when you cancel they keep charging until you call back again. When they “service” it’s a brief 10 minute visual and just wait for stuff to break.

Feel lucky to have found this company. Honest guys who just want to help. Had Joseph Gonzalez out for a quote after two previous companies said I needed a new compressor or full system replacement, and left me without working AC. Joseph had me back up and running in 15 minutes.

The owner Jack and Gabriel the technician were extremely helpful getting our AC unit running again. They were both here endlessly even on a Friday night past 9pm. I would recommend this company to anyone especially for the service that they give
