"Dave Hall was extremely helpful, friendly, and efficient. Excellent service and very knowledgeable. He took the time to service and clean our A/C units, was able to effectively troubleshoot the issues. Other technicians wanted me to replace the air handler entirely, but he was able to resolve our issues and repair the existing units. Dave also educated me about basic maintenance of the outdoor equipment. Really friendly guy, affordable pricing, and just overall a pleasant experience. Highly recommend Dave Hall & Plumbco before you spend a lot more with other vendors. A+ top notch repair!"
