I recently had an HVAC issue and contacted Interstate controls for assistance. They were quick to respond and sent a technician to diagnose the problem. The technician was courteous and skilled, and he fixed the issue promptly. I was impressed with the company's efficiency and professionalism. They didn't try to upsell me on unnecessary services or products, which I appreciated. Overall, I had a positive experience with Interstate controls and would recommend them to others.
