“Barney, helped me again June 24Barney, helped me again June 24 2025. My AC was only blowing out hot air, and the freon line kept freezing up. Barney found one of my freon valves blew out. He replaced it pretty fast and got my AC up and running again. What I really like about Barney is that he tries to figure out the problem and tries to repair it. Instead of like some companies telling you right away that you have to replace your equipment. He is very friendly and professional, and he is very knowledgeable. I also like that is is very reasonable with his prices. I highly recommend Sanford and Sons for your AC repairs. Give him the evening or the next day to get back to you, after you leave a voice message. He always has lots of business, he is that good! Thanks again Barney for getting us back up and running! Much appreciated!“

“Arturo was very quick, responsive and friendly. He came right away, on a holiday weekend and was able to get our AC back on before the hottest part of the heatwave started! Appreciate the work and reasonable pricing.“

“Ryan is my go-to-guy for my rentals in Pittsburg. He has rebuilt these systems and now helps maintain them in peak working order. Very honest and dependable.“

“Black Diamond really came through for us while other companies had alot of excuses. They presented all the options well, and gave us a great price on some well needed maintenance for our system. John and Mike are good people that are easy to work with and personable. They are our "go to" HVAC company now!

If you are looking for some help with your HVAC, I recommend just giving them a call and having a conversation. I was really glad I made that first call.“
