EXCELLENT Based on 8 reviews Posted on JJTrustindex verifies that the original source of the review is Google. We had to use them through our home Warrenty for AC Repair. He was with us every step to try and get it covered and made so many trips to our house and sometimes did not charge us. In the end we had to get a new AC. Everything was installed well and no corners were cut at all. He put in new lines for everything and it works pristine. The price was easily the best I have heard of too.Posted on Kerry MarzoTrustindex verifies that the original source of the review is Google. After a frustrating and dishonest experience with a major HVAC company that tried to void my warranty with false claims about mandatory yearly cleanings that can only be performed by them I was so relieved to find SD Tech HVAC. Seriously, use common sense and call them! Alan was fantastic – quick, efficient, and most importantly, transparent and truthful. He saved me 70% compared to the ridiculous quote I got elsewhere. It's refreshing to find an honest company you can count on!Posted on Brian CentenoTrustindex verifies that the original source of the review is Google.
