Our AC went out when it was 115 degrees outside only 6 months after Air one worked on it ! Highland came out within 24 hours of my call when Air one said to wait 5 days then maybe , Cecil was at my house at 8:00 am diagnosed the issue and repaired the unit in 20 min . Priced us for a small part and repaired some of the other guys sloppy work and was out the door giving us AC relief . There are many clowns out there and calling Highland is how you avoid them .
