"If you are looking for someone honest that actually knows what they are talking about.......Please give Marty Williams a call!!!!!! I had a different company come to our home initially to diagnose our broken AC unit. Within 5 seconds of looking at it they gave me 2 very expensive options. We could either buy a new compressor + Coolant, or we could buy a whole new system for around $6,000. We wanted a second a opinion and spoke to some friends who have dealt with Marty in the past and he came highly recommended with glowing reviews from friends of ours! We called him and explained the situation. He was at our house first thing the next morning. Within seconds we found out that the first company had completely lied and Marty had the unit WORKING in a couple of minutes!! We are now having Marty clean and service both of our units as well as replace our fan motor so that it runs smoothly. We are going to save thousands of dollars and a massive headache because we called him. I cannot say enough good things about how nice and professional he was. So please listen to a happy customer who doesn't appreciate being lied to and call this company!"
