Ice machines on Sunnyvale's blended water

For Sunnyvale, the closest NOAA 1991-2020 normal is a 76.9°F average July high (Moffett Federal Airfield).

Sunnyvale blends SFPUC water with Valley Water and local groundwater. BAWSCA's member profile shows about 56 percent of the city's demand met with SFPUC regional water, which measured 8.1 to 112 ppm hardness in 2025, averaging 60. The rest of the supply is harder, so hardness at the tap depends on the building's location and the season.

That variation means two identical ice machines in Sunnyvale can scale at very different rates. We base descaling intervals on what we find on the evaporator and in the water system, and we recommend a scale-inhibiting filter where we see significant buildup.

Campus kitchens use nugget and flake ice for beverage stations, while Murphy Avenue bars and El Camino restaurants use cube machines. Flaker machines need their augers and gear motors checked regularly; cube machines need their harvest components checked for scale.

Regular cleaning and sanitizing keeps machines inspection-ready. Ice is treated as food, and Santa Clara County inspectors check bins and machine interiors for slime and mold.

Ice machine problems we see in Sunnyvale

• Blended supply. About 56 percent of Sunnyvale's demand is SFPUC water averaging 60 ppm; the rest is harder Valley Water and groundwater.
• Different scale rates by location. Identical machines in different parts of Sunnyvale scale at different rates; we set intervals from what we see.
• Campus flakers. Campus beverage stations use flakers whose augers need regular checks.
• Murphy Avenue cube machines. Bars and restaurants use cube machines whose harvest components suffer from scale.
• County inspections. Santa Clara County inspectors check bins and interiors.
• Filters. Scale-inhibiting filters help where buildup is significant.

What to check at a Sunnyvale ice machine before calling

1. Look at the evaporator for crust.
2. Listen for flaker auger noise.
3. Check the filter date.
4. Look for slime.

A year-round plan for a Sunnyvale ice machine

Because Sunnyvale blends SFPUC water with harder Valley Water and groundwater, inspect each machine's evaporator after the first few months with a new filter and set descaling from what you see. Use a scale-inhibiting filter where buildup is significant, and change it on schedule. Check campus flaker augers at every visit. Clean condensers monthly in warm back rooms on Murphy Avenue. Sanitize and log on schedule for Santa Clara County. Time a freeze cycle each month as an early warning. When replacing a machine, size it for peak demand, since campus and restaurant ice use peaks at the same times. Ask the building manager which water sources serve the building, since that predicts scale.
