“Vasilii from HeyKey has come out to our house a few times to fix our washer. We have a large family so we’re hard on our appliances. He is always honest and thorough. He makes helpful recommendations and you can tell that he’s not just trying to make a sale. I highly recommend!!”

“Vasilii fixed two appliances for us recently. He was on time, professional, and cleaned up after himself. His communication through the process was excellent, and his payment system was easy to use. I recommend his services highly.”

“Van was the service man that came out to replace the ice maker on my 28 year old White-Westinghouse refrigerator. He was very helpful finding an ice-maker that was made for my fridge because the ice-maker was an option in 1997 and the part was hard to find. He fixed the ice-maker but I had a concern about a old brittle water connector. He said he could replace it if he had a brass fitting on his truck. He happen to have one so I had him replace it. Thanks Van for all your help and a job well done. Van gets 5 stars. The price was reasonable but for a 5 star rating it needs to be better. Thats why overall rating was 4 star.”

“I’m very happy with the service from HeyKey Appliance and HVAC Repair. They fixed my GE refrigerator, which had an icemaker issue and a cooling problem in the top section. The technician was amazing, very polite and highly professional. He also shared some great tips on how to take better care of my appliances in the future. Excellent service from start to finish.
