Yes. If you proceed with the repair after the diagnostic, the diagnostic fee is credited toward the total repair cost. ### Will you tell me if the repair isn't worth it? Always. If the repair cost approaches or exceeds the appliance's remaining value, we'll tell you directly and explain why. Honest diagnostics are non-negotiable — we'd rather lose a repair job than give you bad advice. ### When is diagnostic service the right choice? Appliance is making unusual noises or behaving erratically but still running; You're unsure whether repair is worth the cost vs. replacement; A previous repair didn't hold and you want an independent second opinion; You're buying a used appliance and want a professional condition check. ### How much does diagnostic service cost? HighTech Repair Services charges a flat $149 service call for the diagnostic visit, credited toward the repair when you go ahead. After the diagnosis you get a written quote for parts and labor, and nothing is replaced until you approve it. ### Are you an authorized service center? No. HighTech Repair Services is an independent, out-of-warranty repair company and is not affiliated with or authorized by any appliance manufacturer. HighTech Repair Services uses OEM parts ordered against your model and serial number. ### What warranty do you give on repairs? Every HighTech Repair Services repair carries a labor warranty against defects in workmanship; the term is stated on your written quote before work begins. OEM parts carry their own manufacturer warranty, typically 90 days to one year. ## Related services and areas ### Other service options - [Appliance Tune-Up](https://hightechrepairservices.com/appliance-tune-up/) - [Weekend Appliance Repair](https://hightechrepairservices.com/weekend-appliance-repair/) - [Residential Appliance Repair](https://hightechrepairservices.com/residential-appliance-repair/) - [Commercial Appliance Repair](https://hightechrepairservices.com/commercial-appliance-repair/) - [Emergency repair (choose your city)](https://hightechrepairservices.com/seattle/emergency-repair/) ### Appliances - [cooktop repair](https://hightechrepairservices.com/cooktop-repair/) - [dishwasher repair](https://hightechrepairservices.com/dishwasher-repair/) - [dryer repair](https://hightechrepairservices.com/dryer-repair/) - [freezer repair](https://hightechrepairservices.com/freezer-repair/) - [ice maker repair](https://hightechrepairservices.com/ice-maker-repair/) - [oven repair](https://hightechrepairservices.com/oven-repair/) - [range repair](https://hightechrepairservices.com/range-repair/) - [range hood repair](https://hightechrepairservices.com/range-hood-repair/) --- ## About the business - Name: HighTech Repair Services - Type: Independent Appliance Repair (service-area business, Greater Seattle, WA) - Phone: (425) 988-0777 (tel:+1+14259880777) - Email: service@hightechrepairservices.com - Hours: Mon – Sun: 8:00 AM – 8:00 PM, 7 days a week - Technicians: Washington-licensed & insured technicians - Parts: OEM Parts Only - Note: HighTech Repair Services is an independent, out-of-warranty repair company and is not affiliated with or authorized by any appliance manufacturer. - Website: https://hightechrepairservices.com/
