I had excellent sales and customer service experience when I purchased a new A/C & Furnace system summer of 2012. Equipment has been running flawlessly ever since. Due to a work relocation we needed to sell the house and the buyer's inspector found where some trusses in the attic had been removed/replaced for the installation of the new furnace. A truss expert came in and recommended the trusses be repaired with new plating. Wolfgang's came out and looked at the trusses and agreed to pay for the remediation. Wolfgang's is absolutely an up-standing and respectful company to do business with and I highly recommend them. To be clear, the truss was replaced as found by the installers and there were no structural issues, however, since the sale of my house relied upon the truss work being certified by a structural engineer, Wolfgang's stepped up to the plate to make it right. They deserve a 5 star rating for customer service and professionalism. Thanks guys! :)
