This was my first time using Quality Refrigeration Services. They installed a condensate drain pump, and it couldn't have gone better. I do this for a living in Canada - where I live - but I needed to find someone in Columbia to fix an issue for my daughter. I knew exactly what I was looking for, and they fit it to a "T" - that's coming from someone who does this for a living. They responded to my call right away. I told them what I needed them to do, and they sent someone out the same day. It all turned out very good. I would take them back, and I would definitely recommend them!
