Ziv Ben-YehudaLocal Guide · 32 reviewsiTotal number of Google reviews Ziv has written across all businesses on Google Maps, not just this one.
I contacted Heise’s about a Sub-Zero repair. They initially responded, but I received no reply to follow-up emails on October 19 and 21 asking to confirm a proposed October 23 visit and clarify repair fees and parts. As of October 22, the appointment was still unconfirmed, so I decided to look elsewhere. This review is about communication and scheduling, not repair workmanship.
Response from the owner · 4 days ago
Ziv, thank you for your review. We have an amazing team who work hard every day to provide excellent customer service. We are proud to serve thousands of amazing customers throughout San Francisco and the Bay Area every year, and we truly appreciate every one of them. We wish you the best of luck with your repair.

Eve Solomon4 reviewsiTotal number of Google reviews Eve has written across all businesses on Google Maps, not just this one.
I feel that the pricing is quite strange. They charge for the initial service call and then they charge for the second service call when they come back with the parts so I feel like they’re like double dipping.

Response from the owner · 3 days ago
Hi Eve,
Thank you for sharing your feedback. We understand how the cost of a return visit can be frustrating, especially when parts are needed to complete a repair. Our service call charges cover the time and work involved at each visit, but we appreciate you bringing your concerns to our attention. We always want our pricing and process to be clear to our customers.
