Work well done & in a timely manner. Honest, professional & courteous. Price can’t be beat. Will use again in the future when need arises. Highly recommend Tri-County Heating & Air Conditioning.Fairview Baptist Church, Google Review
Tri-County gets 5 stars (I’d give them 10, if I could), because they are smart, inventive, intuitive, they listen to your concerns, and they have stellar customer service and followup. They know what they are doing, and can help you get the maximum functionality out of whatever system you have. Jackie C. Austin, TX Yelp Review
After four other vendors tried to fix our unit, it wasn’t until Tri County came out and knew exactly what was wrong. They’re by far the most knowledgeable and courteous air conditioning company in the Austin area!Donald H. Austin, TX Yelp Review
