Don Raymond Barch
Owner
Don has been installing solar systems. He and his partner Kane Hoffman are unscrupulous in that they quote a price and then try to get 5 or 6 new contracts signed by someone other than the homeowner. They start low and escalate the price to more than double the original amount. Ethics are out the door on this company and they have to be watched closely.
Also the system was installed completely different than the approved drawings and had to be removed and re-installed. Businesses like this should not be in business as it gives the rest of the contracting community a bad name.
