Marine Humidity & Coil Icing
Persistent coastal moisture restricts evaporator airflow and freezes coils. We evaluate defrost heaters, sensors, termination switches, and door seals—not just box temperature.
Fast response. Inventory stabilization. Specialized expertise.
AllBrands Refrigeration keeps Western Washington businesses running when critical cooling equipment fails. We service walk-in coolers, freezers, ice makers, premium restaurant and beverage equipment, along with scientific, medical, and laboratory systems requiring precise temperature control.
Serving Seattle, Tacoma, Olympia, and communities along the I-5 corridor with dependable emergency support, day or night.

Regional Operating Conditions
Persistent coastal moisture restricts evaporator airflow and freezes coils. We evaluate defrost heaters, sensors, termination switches, and door seals—not just box temperature.
Temperature swings alter rooftop condensing pressures and compressor loads. We analyze oil return, expansion valves, and floodback risk under actual operating conditions.
Rain corrodes contactors, wiring, and controls on outdoor units. Integrated electrical and refrigerant diagnostics help prevent false assumptions.
Waterfront operations near Puget Sound and Commencement Bay face faster coil and line deterioration. Early detection can stop leaks before major system failure.
Diagnostic Intake Checklist
Current reading, rate of rise, and product exposure risk.
Record controller fault codes before resetting the control.
Report evaporator frost, standing water, and drain-pan overflow.
Report continuous running, frequent cycling, buzzing, or changes after a power outage.

Refrigeration Benchmarks
Targets vary by equipment, application, refrigerant, load, and manufacturer. OEM requirements take precedence.
Walk-In Cooler Temperature
35°F–38°F
AllBrands recommended operating target; provides margin below the 41°F food-safety threshold where applicable.
Walk-In Freezer Temperature
−10°F–0°F
AllBrands recommended target to help protect inventory during loading and defrost cycles.
Compressor Discharge
OEM-specific
Verified against the applicable compressor operating envelope.
Superheat / Subcooling
OEM / system target
Measured for the expansion device, refrigerant, load, and system design—never estimated.
Post-Repair Evacuation
Below 500 microns
Deep vacuum verified with an isolated standing decay test when evacuation is required.
Frequently Asked Questions
Our fleet stages daily along the I-5 corridor from Olympia through Tacoma, Federal Way, Kent, Renton, SeaTac, and Seattle — placing us within 30 minutes to 2 hours of most Pierce County, King County, and Thurston County facilities under normal traffic conditions. For Port of Tacoma cold logistics, SeaTac airport food service, and Bellevue pharmaceutical cold chain, we maintain dedicated on-call technicians year-round. Cities like Auburn, Puyallup, Fife, Burien, Tukwila, and Lakewood fall within our primary rapid-response radius. Bremerton and Gig Harbor are served via peninsula staging. We respond faster than national chains because we live and operate here — not dispatching from a regional hub hours away.
Yes — 24 hours a day, 365 days a year, including all major holidays. Call 206.486.4750 and you reach the on-call technician directly — not an answering service, not a call center, not a scheduling queue. Emergency walk-in cooler failures, walk-in freezer breakdowns, ice machine failures, reach-in cooler outages, and commercial refrigerator failures on weekends and holidays are dispatched at the same priority as weekday calls. A Sunday morning freezer failure at a Tacoma restaurant is a critical event. We respond accordingly — with a fully equipped service vehicle, not a promise to call back Monday.
Yes. We perform pre-inspection refrigeration condition reviews using the applicable Washington Food Code provisions, including WAC 246-215-03525 for time/temperature control for safety food held at 41°F or less and WAC 246-215-03500 for commercially processed frozen food maintained frozen. The review can include thermometer accuracy checks, door-gasket condition, condensate drainage observations, evaporator fan operation, controller alarm settings, and documented box-temperature pull-down. We identify AllBrands service recommendations separately from regulatory requirements; the regulatory authority determines compliance. A timestamped service report can support—but does not replace—the health inspection.
In Western Washington's marine climate — unequivocally yes. Our internal service data shows facilities on quarterly PM contracts experience 73% fewer emergency calls and extend compressor life by an average of 3.2 years compared to reactive-only accounts. A standard PM visit ($285–$425 depending on unit count) includes: evaporator and condenser coil cleaning, refrigerant charge verification by subcooling method, electrical connection tightening, defrost termination and initiation testing, crankcase heater confirmation, suction superheat measurement, and door gasket inspection. Compare that to an average emergency repair bill of $1,800–$4,500 plus spoiled inventory replacement. For restaurants in Seattle, Tacoma, Renton, and Bellevue with 6-figure perishable inventory exposure, the math is not close.
Yes. R-22 has been fully phased out of production under the EPA Clean Air Act Section 608, and remaining recovered stockpiles now exceed $85/lb — making continued R-22 operation economically irrational. We perform engineered retrofits to R-407C for medium-temperature cooler applications, and R-448A (Opteon XP40) or R-449A (Opteon XP10) for low-temperature freezer applications. Each retrofit includes: full refrigerant recovery and EPA 608-compliant disposal, compressor oil flush and change to compatible POE (polyolester) oil, TXV or EEV adjustment or replacement for the new refrigerant's pressure-enthalpy curve, evacuation to <500 microns, and full recharge with superheat and subcooling verification. Most single-compressor walk-in retrofits in Seattle, Tacoma, Bellevue, and Kent are completed in a single service day.
Western Washington's combination of persistent marine humidity (70–85% RH year-round), freeze-thaw cycling with narrow temperature deltas, heavy rainfall (38–50 inches annually), and Puget Sound salt-air corrosion creates a failure profile that generalist HVAC contractors rarely recognize. The top 5 Pacific Northwest–specific commercial refrigeration failures we diagnose are: (1) evaporator coil icing and floodback from marine moisture infiltration and narrow cooler-to-ambient temperature deltas — common in Tacoma, Bremerton, and Seattle waterfront facilities; (2) condenser coil fin corrosion from salt-air exposure within 3–5 miles of Puget Sound; (3) compressor thermal shock and refrigerant migration from daily freeze-thaw swings; (4) electrical contactor and terminal block corrosion from rain infiltration into rooftop NEMA enclosures; and (5) condensate drain line freezing and pan overflow during winter cold snaps. None of these are common in dry-climate or desert service areas — they require Pacific Northwest–specific diagnostic protocols.
AllBrands services the full spectrum of commercial cold-side equipment: walk-in coolers, walk-in freezers, blast freezers, reach-in coolers, commercial refrigerators, commercial freezers, prep tables, chef bases, display cases, open-air merchandisers, ice machines (cubers, nugget, flake — Hoshizaki, Manitowoc, Scotsman, Ice-O-Matic, Follett), soft serve machines (Taylor, Carpigiani, Stoelting, Electro Freeze, Spaceman), frozen carbonated beverage (FCB) units, and commercial HVAC systems in food service environments. We service all major OEM brands including True Refrigeration, Turbo Air, Beverage Air, Traulsen, Delfield, Master-Bilt, Norlake, Kolpak, Hussmann, and Heatcraft. If it runs refrigerant and serves a commercial operation in Western Washington — we repair it.
