Best Services Viking in Greensboro NC

Advanced Appliance was chosen by our home warranty company to provide repairs to one of our heat pumps that wasn't cooling our upstairs.  Their first visit out was the beginning of May and here we are going into August, and our heat pump is STILL not working.  They've replaced the condenser coil (then had to come back out and fix it because their technician cut corners).  They've cancelled 2 of our scheduled appointments back-to-back for a technician to read the dye they injected last time, and this is the 2nd time this summer they've had to inject our system with dye.  Every guy that comes out swears he's fixed it; then a couple days later our upstairs temp is back up in the high 80s/low 90s.  This company does not understand that we have jobs, too, so every time they miss their 5-hr. window, I miss an entire day of work.  They're not reliable, and I can't honestly say I think they know what they're doing.
