Frequently asked questions

We understand that a Sub-Zero failure means potential loss of thousands of dollars in perishable goods. Our emergency response team is available 24 hours a day, 7 days a week, including holidays. In the greater Milwaukee, Madison, and Green Bay metropolitan areas, we typically arrive within 60 to 90 minutes of your call. For other Wisconsin locations, we guarantee same-day service when you call before 2 PM. Our emergency dispatch line is (608) 271-0604, and a live technician, not an answering service, will take your call and coordinate immediate dispatch.

Yes, exclusively. Sub-Zero appliances are engineered unlike any other refrigeration system on the market. Their dual-compressor technology, NASA-inspired air purification systems, and microprocessor-controlled environments require specialized training and diagnostic equipment that general appliance repair companies simply do not possess. By focusing exclusively on Sub-Zero, our technicians develop an unmatched depth of expertise across every model and generation. We know these machines inside and out because it is all we do, every single day. This specialization means faster, more accurate diagnoses, fewer return visits, and repairs that last. Sub-Zero is headquartered right here in Madison, Wisconsin, and we are proud to be the local experts servicing the brand where it is built.

We believe in complete pricing transparency. Minor repairs, such as thermostat adjustments, gasket replacements, and sensor calibrations, typically run $150 to $300. Major repairs including compressor work, control board replacement, and sealed system service range from $600 to $1,500 depending on model and parts required. Our diagnostic fee is $89, which is waived if you proceed with the repair. We always provide a detailed written estimate before any work begins, and there are no hidden fees, trip charges, or after-hours surcharges. The price we quote is the price you pay.

Absolutely, without exception. We use only genuine Sub-Zero OEM (Original Equipment Manufacturer) parts sourced directly from authorized distribution channels. Aftermarket parts may cost less upfront but often cause compatibility issues, void manufacturer warranties, and fail prematurely. Genuine OEM parts are engineered to the exact specifications of your unit, ensuring perfect fit, optimal performance, and maximum lifespan. All OEM parts carry the manufacturer's warranty. We maintain an extensive inventory of the most commonly needed Sub-Zero parts in our Madison warehouse, which allows us to complete many repairs on the first visit without waiting for parts to ship.

Every repair performed by Sub Zero Repairs comes with our industry-leading dual warranty: a full 1-year warranty on all parts and a 90-day warranty on labor. If any part we install fails within 12 months, we will replace it at no charge. If the same issue recurs within 90 days due to workmanship, we will return and resolve it at no cost for labor. This warranty applies to all services including emergency repairs, and it transfers with the appliance if you sell your home. We stand behind our work because we use only genuine OEM parts installed by factory-certified technicians, a combination that virtually eliminates premature failure.

Yes, we provide full-service Sub-Zero installation for new units and replacements. Our process begins with a pre-installation site survey where we verify electrical requirements, water line access for ice makers, ventilation clearances, and cabinetry dimensions. On installation day, our team handles complete unpacking and inspection of the unit, precise leveling and alignment within your cabinetry, connection of water lines and electrical, integration with custom panel fronts if applicable, a full system calibration and temperature verification, and a comprehensive walkthrough of all features with you. The entire process typically takes 2 to 4 hours depending on the model and configuration. We coordinate directly with your contractor or kitchen designer if this is part of a larger renovation project.

Each maintenance visit includes a comprehensive condenser coil cleaning to prevent overheating, door seal inspection and conditioning, temperature calibration verification across all zones, evaporator and fan motor inspection, drain line clearing and sanitization, water filter replacement, air purification system check, full electrical connection inspection, and a written performance report documenting the condition of all major components. We offer two plan tiers: our Standard plan includes one annual visit for $199, while our Premium plan includes two visits per year for $349 and adds priority scheduling, a 15% discount on any needed repairs, and extended diagnostic coverage. Annual maintenance can extend the life of your Sub-Zero by years and prevent costly breakdowns.

We proudly serve the entire state of Wisconsin with a focus on the major metropolitan areas and their surrounding communities. Our primary service areas include Milwaukee and the greater Milwaukee metro (Waukesha, Brookfield, Wauwatosa, Shorewood, Whitefish Bay, Mequon, Cedarburg), Madison and surrounding communities (Middleton, Fitchburg, Sun Prairie, Verona, Waunakee), Green Bay and the Fox Valley (Appleton, Oshkosh, Neenah, Menasha, De Pere), Kenosha and Racine counties, and the Lake Geneva and Elkhorn resort areas. For locations within 30 miles of Milwaukee, Madison, or Green Bay, we offer same-day service. For other Wisconsin locations, we typically schedule next-business-day appointments. There is never an additional travel surcharge regardless of your location within the state.
