Business ProfileforColumbia NW Heating OR, LLC

I hired this company to do a repair on my ac unit based on Home Depots "preffered contractors" recommendation.The first technition that came out determined that the control board for my system had burned out and the entire system needed replacement. While I was scheduling for the sales appointment the tech said he did me a "favor'. He was able to rig my ac to run by using electrical tape to bypass the emergency shut down switch. He told me "hopefully this will last until we can get the new unit installed".What he didn't tell me was that if something happened the unit it would not shut itself down to prevent further damage.3 days later after running 24/7 on 98degree days the condensation pump could not keep up with the unit and could not shut unit down. Instead. It created a flood in my garage and destroyed property.Home depot accepted responsibility as they sent them to my home. They even filed a claim with their insurance company "*******".After weeks of run around, ******** kicked issue to Columbia nws own insurer.Federation. They dismissed my claim stating their "investigation" shows their insured as not liable. The guy basically called me liar and said the tech did not leave with anything running. They also made several false statements about my unit that I have direct proof refuting.No inspection ever happened. No one ever even came to my home to view unit OR damage other than the company in dispute. As I was in contract, I went ahead with the install. Manager *** made it seem like he was actually going to do something to resolve the situation..but apparantly that was only until my payment cleared. Currently, the install they did has failed inspection due to electrical issues and wrong sized safety drain pan put under unit. Inspector said entire thing needed to be removed and redone. I have heard 0 from them.how many opportunities do I have to give them to fail?I will be filing a suit against them, insurer and depot can come along with them.
