AC wasn't cooling. Jacob came out same-day and saved the day. Not only did he fix the problem but also stuck around to thoroughly check and test the whole system including cleaning the air scrubber filters. I appreciate Jacob's thoroughness and commitment to going above and beyond to provide excellent customer service. Thanks Jacob and RAC!

As always, these guys right here are the real deal! They don't mess around! They do amazing work and stand by their work. Jessica is so nice and pleasant! Jacob is hands down the greatest. My mom gave him goodies before he left. My mom and dad said, "they don't make kids like Jacob anymore, that is one good kid". Thank you Reliable, you guys are amazing!

Making an appointment with this company was quick and easy. They were able to get someone to our house first thing the next morning. Our technician, Sam, called on his way and he showed up right on time. He was professional and knowledgeable. I have much respect as he worked hard up in our attic. He diagnosed the problem quick, went and picked up the necessary part, came back and installed a new fan. He got us up and running again. I am very thankful for the service we received and I definitely recommend this company. Thank you Sam!
