What your neighbors say
I cannot thank South County Air Services enough for impeccable customer service. Behshad came out on a Saturday to check my heating unit (failing motor). He was professional, knowledgeable, courteous and thorough – extremely fair pricing, with open and honest communication. Highly recommend. Five star plus!
Super impressed with our experience. We needed to replace our 40+ year old furnace, and from the first call everything was easy and clearly explained. Responsive, great follow-up, great pricing, timely booking, installers on time and prepared, clean install, no mess left.
I am grateful to the technician who inspected my HVAC system today. I feel he did a thorough inspection and told me the truth about my unit. I had two other companies beforehand – the first gave me a report that would call for major expenditure.
You will not find a more honest and knowledgeable HVAC tech. They show up on time and are very professional, but most of all will not try to upcharge you. He could have charged me significantly more but cares about diagnosing the actual problem. I found my HVAC tech – 10 star review if I could!
It’s not often you find an honest business willing to give suggestions over the phone to troubleshoot why my HVAC wasn’t working – without charging me. After a couple minutes we determined my breaker popped and all I needed was to reset it. I appreciate Behshad and will definitely use him in the future.
I spoke with the owner on a Saturday morning and he was at my house within 45 minutes. Another company wanted $3,000 in repairs; Behshad recommended a simple $250 repair that fixed the issue. Very honest, thorough, and reliable!
