- CPChad P1 day ago5.0Prompt emergency ac service! Highly recommend. Knowledgeable and professional technician. Hunter thoroughly worked through the unit to diagnose and solve the issue on the spot!
- SSSydney Simpson4 days ago5.0I would recommend this company to anyone I know! I have health issues that made fixing our ac a top priority and even though they were booked up for the holiday I was squeezed in and it was fixed the same day. I was expecting a quick temp fix but he spent most of the day ensuring it was working properly and helping me understand the entire system to prevent future issues! I am so glad I decided to call this buisness and am now a loyal customer due to the extremely amazing service.
- SWSuzanne WhatleyJun 26, 20265.0My experience was fantastic. Mike came out and fixed everything. We had expensive plumbing done by Brian B Quick and paid $3000 and drain hoses and laundry sink were never connected. Mike said it was shoddy work and repaired everything for under $1000. You have all my plumbing business from now on!
- TCTerri ClaytonJun 25, 20265.0I had an a/c issue. Hunter was my technician & he was so very nice & respectful. I had the same exact issue with my A/C 6 or 7 years ago & I actually paid more to fix it than this time. Even the original person I spoke with when I called to inquire about their services was so pleasant. All in all, they are a great company & I have nothing but good things to say about them. I will definitely put them on my speed dial.
