Foster services and maintains walk-in coolers, walk-in freezers, and commercial refrigeration of any brand — not just Foster units. We handle preventive maintenance (coils, charge, defrost, gaskets, drains), emergency repair when a box stops holding temperature, and door, gasket, and hardware replacement on existing walk-ins. Based in Hudson, NY. Call 518·671·6036 for a priority temperature call.
We service every brand — not just Foster
Most refrigeration failures don't announce themselves. A gasket hardens, a coil clogs, a defrost cycle sticks — and then one morning the box is at 50°F with a full load of product inside. Foster's technicians service walk-in coolers, walk-in freezers, and commercial refrigeration regardless of who built the box: Foster, Norlake, Kolpak, Amerikooler, US Cooler, or an unbranded older unit. The same engineering team that fabricates military-grade walk-ins in Hudson knows how every one of these boxes is put together — and how they fail.
What we do
- Preventive maintenance — scheduled visits that clean condenser and evaporator coils, check refrigerant charge and pressures, verify temperature and defrost cycles, adjust door closers and hinges, and clear condensate drains before they cause a failure.
- Emergency & temperature repair — when a walk-in stops holding temperature, product is at risk within hours. We diagnose gaskets, icing, refrigerant, defrost faults, and compressor issues and get the box holding again.
- Doors, gaskets & hardware — we fabricate and fit replacement doors, magnetic gaskets, self-closing hinges, and latches for any brand, restoring the tight seal that keeps energy bills and compressor wear down.
- Diagnostics & efficiency checks — a box that runs constantly is telling you something. We find the leak, the failing seal, or the undersized system behind a walk-in that can't hold its target temperature.
- Panel & floor repair — dented, delaminated, or water-damaged panels and diamond-plate floors repaired or replaced, drawing on Foster's own panel fabrication.
If a repair keeps recurring, it's often cheaper to replace the box — use the cost calculator to compare, or configure a new build. Not sure yet? Start with the troubleshooting guide.
The two cheapest repairs to stay ahead of are door gaskets and condenser coils. A hardened gasket or a coil packed with grease makes the refrigeration run constantly — burning energy and shortening compressor life — long before it becomes a failure. One preventive visit a year usually pays for itself.
Commercial refrigeration only
Foster is a commercial refrigeration company. We service and build walk-in coolers, walk-in freezers, reach-ins, and commercial cold storage for restaurants, grocers, institutions, marine, and cold-chain operators. We do not sell or service household or residential appliances — home refrigerators, kitchen French-door units, or consumer freezers. If you need a domestic appliance, an appliance dealer is the right call; if you run a commercial kitchen or facility, you're in the right place.
Who we help
Foster service and maintenance supports restaurants, cafés, bars, hotels, schools, hospitals, bakeries, delis, grocery and convenience stores, ghost kitchens and commissaries, and marine and institutional operators — anyone running a commercial walk-in or refrigeration system that has to stay cold. Whether you own a Foster box or inherited someone else's, we keep it holding temperature.
Frequently asked questions
Do you service walk-in coolers you didn't build?
Yes. We service and maintain walk-in coolers, freezers, and commercial refrigeration of every brand — Norlake, Kolpak, Amerikooler, US Cooler, unbranded older builds, and of course Foster. Tell us the make and rough age and we'll bring the right parts.
What does preventive maintenance on a walk-in cover?
A visit typically covers cleaning condenser and evaporator coils, checking refrigerant charge and pressures, verifying temperature and defrost cycles, inspecting and adjusting door closers, hinges, and gaskets, clearing condensate drains, and confirming the box holds its target temperature. Catching a worn gasket or dirty coil early is far cheaper than an emergency call after product is lost.
My walk-in cooler is not holding temperature — can you help fast?
Yes. A box that isn't cooling puts product at risk within hours, so temperature problems are priority calls. Common causes are a failing gasket, an iced-up evaporator, low refrigerant, a stuck defrost cycle, or a failing compressor. Call 518·671·6036 with your temperature and symptoms — and the troubleshooting guide covers first steps while you wait.
Do you replace doors, gaskets, and hardware on existing boxes?
Yes. Doors, hinges, magnetic gaskets, and latches wear out long before panels do, and a leaking door makes the refrigeration run constantly. Foster fabricates and fits replacement doors, gaskets, and closers for walk-ins of any brand, restoring a tight seal and cutting wasted energy.
