"Best AC company in San Antonio. My two units went out last week and a friend referred me to Carnes and sons, I called Clint and we agreed on the job then he sent Juan and the team next day to replace the two units and have it done in one day. They are very honest, fast and cleaned the space after finishing and I am really grateful to them. I will recommend them to all my family and friends."
"Great price. I am absolutely thrilled with the service I received from Carnes and Sons Air Conditioning. I needed a full system replacement in a home with a challenging setup, and after receiving multiple quotes, Carnes was the only company with the creativity, expertise, and confidence to deliver exactly what I wanted. Their workmanship, attention to detail, responsiveness, fair pricing, and speed of installation were all top-notch. They made a complex project feel seamless and stress-free. It's rare to find a company that combines technical skill with such a high level of customer care. I am truly grateful for their work and would recommend Carnes and Sons without hesitation to anyone looking for HVAC service done the right way."
