TECHNICAL INFO

 

• Do you "repair" or "replace" my entire climate control unit?
  
  We don't specifically do either of those things. What we do is replace all the internal circuit boards inside the CCU with new and upgraded parts.
  
  Now, all the "external" parts, such as the buttons, switches, knobs and metal casing, are cleaned to be best of our abilities in order to freshen up the look of the CCU.
  
  If any of these parts are damaged or worn out, our technician will suggest that we replace them with used spare parts that will look almost like new.
  
  
• The controls in my CCU are not working the way that I expect them to. Could this be the CCU that is defective, or could it be something else?
  
  If your CCU is acting a little crazy, and like it has a mind of its own, it is 100% that the CCU is defective. 
  
  These units stop working correctly because of failures in 7 different parts of the unit. This makes it VERY hard to fix with a conventinal repair. That is why we opted to completely upgrade all the internal circuit boards with brand new technology.
