NEVER AGAIN! An $85 service call turned into a $729 bill that resulted in NO FIX for my air system. The tech checked out our heat pump because we weren't getting cold air. After inspecting, he said the problem WAS NOT the air system but the coil in the furnace which is $3,000 to replace. After doing some research, turns out, the coil is only about $900!!! I had another company come out and look. Guess what? It WAS the outside air unit! So, if I had gone along with Vance, they would have replaced the coil for $3k and it still wouldn't have been fixed. Then the tech wanted to do a pressure test on the system and said that would be an additional $600-$800. The other HVAC company that came out did the pressure test at their hourly rate--not at an additional charge of $600+! I feel totally scammed by Vance and to top it off, I have NOT received an invoice to show me why I was charged $729.00 although the said they would send one and this service was done back on Aug 5th!! NEVER AGAIN!!!
