Walk-in freezers through Livermore's summers

For Livermore, the closest NOAA 1991-2020 normal is a 89.0°F average July high (Livermore).

Freezers in Livermore work hard every summer. The compressor has to move heat across a large temperature difference, and with afternoon highs near 90°F that difference grows. A freezer that runs fine in spring may begin tripping on overload or drifting toward 10°F in July.

Restaurants near the outlet center and downtown push freezers hardest on summer weekends, when traffic and deliveries peak at the same time as the heat. Keeping the condenser clean, the door sealed and the evaporator clear of stacked product helps a freezer get through those days.

Livermore's winter nights are cold, with average January lows around 39°F at the NOAA station. That matters for freezers with outdoor condensing units and drain lines. Drain line heaters keep defrost water from refreezing, and when they fail the first sign is often ice on the freezer floor in winter.

If you have a freezer alarm, note the time and the temperature, and check whether the coil is heavily iced. That information helps us decide whether we are looking at a defrost problem or a capacity problem.

Freezer problems we see in Livermore

• Freezer lift in Tri-Valley heat. A freezer moves heat from 0°F out into air that, on a Livermore roof in July, can pass 100°F. That lift is far larger than a cooler's, and it is why freezers are the first equipment to drift when the heat arrives.
• Overload trips on summer weekends. Compressors that trip on overload and restart on their own are overheating. In Livermore it is usually a dirty condenser, a slow condenser fan or a charge that has drifted low over several seasons.
• Restaurants near the outlet center. Busy weekends near the San Francisco Premium Outlets bring deliveries and door traffic together with the heat. Freezers in those kitchens need clean coils and good door seals to get through.
• Frost from humid event deliveries. Event caterers load product that may have sat in a warm van. Moisture from that product and from open doors builds frost on the coil, so defrost settings need to match the real load.
• Cold winter nights and drain heaters. Livermore's January lows average around 39°F. Drain line heaters that failed unnoticed in summer show up in winter as ice spreading across the freezer floor.
• Door heaters on exterior freezers. Freezers with doors to the outside, common at wineries and warehouses, depend on frame heaters to keep the door from freezing shut on cold, damp mornings.

What to check at a Livermore freezer before calling

1. Read the freezer at 3 PM on a hot day and compare with the morning reading.
2. Listen at the condensing unit for the click of repeated restarts.
3. Look for ice spreading from the drain area on cold mornings.
4. Check whether the coil is clear right after a defrost ends.

A year-round plan for a Livermore freezer

Livermore freezers should be serviced every spring with a condenser cleaning and charge check, because summer afternoons are when they fail. Through July and August, read freezers at mid-afternoon and note any drift. Wineries and event caterers should review defrost settings before harvest and wedding season. In November, test drain line and frame heaters before cold nights.
