A burning smell was coming from my mom's upright freezer. We called Hassan at Wise Appliance Service in the late afternoon/early evening and he was able to come out the next morning. He quickly found the problem (heating element had dropped and was touching plastic) and fixed it. Problem was diagnosed and fixed in about 30 mins! Hassan was knowledgeable, courteous and very friendly. Would highly recommend him to anyone needing an appliance repair.
