Local Feedback
"Star Appliance Repair LLC did a great job fixing my Whirlpool fridge. The freezer had major ice buildup and was leaking from the bottom, but the technician arrived on time, clearly explained the issue and pricing upfront, and quickly got everything working properly again."
"Look no further if you need a chest freezer or any other refrigerated unit diagnosed and repaired! Sean was on-time and FIRST CLASS when he arrived to assess my deep freezer. I googled and found Star Appliance among others but Star was the only company that applied the diagnose charge to the repair and parts. Sean diagnosed, repaired and explained everything, and even showed me how to maintain the freezer for optimal performance going forward. So look no further if you need any refrigerated appliance repaired!"
"Sean from Star Appliance is super. We had a problem with the mother board of a 16 year old Dacor refrigerator. Most appliance repair companies we contacted wouldn't work on Dacor. Luckily we found Star and Sean got the mother board repaired and everything working perfectly — the day before we were to host a party. We will definitely use Star Appliance going forward for all of our appliances."
