Running a busy kitchen isn’t just about recipes and reservation lists—it’s about uptime. If your walk-in drifts a few degrees or your ice machine limps through happy hour, you’ll feel it on your food cost, your labor, and your reviews. I’m Rick Callahan, owner of Plumbing Supply And More, and I’ve spent decades helping restaurants keep coolers tight, ice crystal-clear, and beverage lines crisp. These are the Refrigeration Supply House Tips for Restaurant Owners I share with the chefs, GMs, and facilities leads who call me when it’s crunch time. If you want straight, field-tested guidance—and everything you need under one roof—you’ll see why the smartest operators make us their first call.
Before we dive in, a quick promise: you’ll get specific product names, model numbers, specs, and realistic price ranges. And whenever you’re weighing a choice, I’ll tell you exactly what I’d install in my own place. Need to talk it through? Call our technical team—we’ll pull spec sheets, confirm parts compatibility, and set up same-day delivery within our 50-mile service radius.
Reading Refrigeration Like a Pro: What Fails, Why It Fails, and What to Stock
Here’s the truth: 80% of cold-side emergencies I see could’ve been prevented with the right parts on hand. Your walk-in and reach-ins fail at predictable points—electrical connections, controls, fans, and airflow.
- Common weak links: Condenser fan motors (ECM or PSC) and blade assemblies Evaporator fan motors with ice buildup and worn bushings Door gaskets, sweeps, and magnetic strips that leak cold air Thermostats and digital controllers (Carel, Emerson, Danfoss) Start components: capacitors, contactors, and relays
Pro tip: Stock a “Weekend Saver” kit for each unit. Label a clear bin with your model number(s) and include:
- Run/start capacitor: match µF and voltage. For a common 1/3 HP condensing unit, you’ll often see 35/5 µF at 440V ($12–$25). Contactor: 30A definite purpose, coil voltage matched (24V, 120V) ($18–$40). Fan motor: Packard 5WCP or Evergreen equivalent, plus the right fan blade ($60–$150). Thermostat or digital control: Carel IR33 series or Danfoss ERC 213 ($85–$260). Door gasket matched to brand and size (True, Turbo Air, Delfield) ($30–$120).
Why these? Because 90 minutes on a Saturday with one bin beats a 6-hour downtime and a walk-in full of product at risk.
And yes—if you’re searching “plumbing supply near me” or “plumbing supply store near me,” that’s us; we stock the cold-side essentials alongside plumbing so you don’t waste time bouncing between suppliers. We’re the closest plumbing supply with real refrigeration knowledge, and we back it up with hands-on guidance.
Matching Parts to Equipment: Brand-Specific Nuances That Save Headaches
I see restaurants lose days waiting on the wrong parts because someone guessed. Don’t guess. Get the model and serial, then call us. For reference:
- True Refrigeration T-49 and TPP series: OEM door gaskets, ECM fan motors, and Carel controllers are common replacements. Gasket fit matters; a 1/8" error ruins seal integrity. Hoshizaki KM-660/901 ice machines: Water inlet valves, float switches, and pump motors are the frequent culprits. We stock Hoshizaki parts and compatible water filtration (Everpure EV9324-02) that doubles your ice-maker lifespan. Manitowoc Indigo NXT: Board updates and water level probes commonly needed. Proper filtration is mandatory; we carry Pentair/Antunes systems sized for your ice production. Beverage-Air and Delfield reach-ins: Door closers and evaporator motors (9W–16W range) are typical. We carry Packard, Regal, and OEM blades.
Insider secret: When replacing a condenser fan motor, always match rotation (CW/CCW) and shaft size, and check amps draw against nameplate. Undersized motors overheat; oversized motors can trip your control board. We’ll help you read the data plate and choose the exact unit—no guesswork.
And if you’re comparing where to buy parts: Unlike generic big box retailers, Plumbing Supply And More stocks professional-grade components that match your equipment’s specification, not “close enough” substitutes.
Electrical and Control Essentials: Don’t Let a $20 Part Close Your Kitchen
Most “my cooler is warm” calls boil down to control and electrical issues. If you run restaurants, build this into your maintenance routine and stocking list:
- Capacitors: Always keep a spare. Microfarads must match; voltage can be equal or higher (never lower). We stock Titan Pro, Packard, and MARS—reliable and in-spec. Contactors: Choose by coil voltage (24V for most controls, 120V on some older setups). Check pole count and amp rating. MARS 61730 and 61724 are workhorses. Defrost controls: For walk-ins with electric defrost, look at Paragon 8145 series timers (manual and auto defrost cycles), or electronic retrofits (Dixell XR20C/IR33). Temperature controllers: Carel IR33 and Dixell XR series are industry staples. We pre-wire harnesses on request to cut install time from 90 minutes to 30.
Budgeting: Expect $15–$45 for capacitors, $18–$45 for contactors, $85–$260 for digital controls, plus 30–120 minutes of install time depending on access. We’ll print wiring diagrams and step-by-step install guidance—call our team any time.
When Home Depot and Lowe’s fall short on commercial-grade control options, contractors trust Plumbing Supply And More for stocked, spec-correct controls, wiring diagrams, and on-call tech support.
Airflow, Filtration, and Coil Hygiene: The Cheapest Insurance You’ll Ever Buy
You know how many “bad compressors” were just suffocated coils? Too many. Set a schedule:
- Condenser coils: Clean monthly in greasy kitchens; quarterly elsewhere. Use Nu-Calgon Coil Cleaner and a soft brush. Consider a washable pre-filter wrap if your unit faces a fryer line. Evaporator coils: Treat biannually; keep fins straight and drain pans clear. We stock fin combs and pan treatments that prevent biofilm. Filters and water treatment for ice machines: Everpure and Pentair systems sized to your machine production. For a 500–900 lb/day ice machine, budget $180–$400 for filtration. Replace every 6 months—don’t push it. Door gaskets and sweeps: Inspect quarterly; replace when you see cracks, deformities, or poor magnet adhesion. A bad gasket can add 20% to your power draw.
Real-world example: A bistro we serve in the downtown district cut compressor runtime by 30% after we swapped gaskets on two True reach-ins and cleaned coils properly. Their monthly power bill dropped by hundreds. That’s not theory; that’s what the meter said.
While other suppliers focus on quantity, Plumbing Supply And More prioritizes quality and expertise—we’ll show your team how to clean coils the right way and stock the right cleaners and tools.
Choosing the Right Refrigerant and Components: R290, R404A, and What’s Next
Refrigerants are changing fast. If you’re buying or replacing components, here’s what matters:
- R290 (propane) is now common in reach-ins and undercounters. It’s efficient and eco-friendlier but flammable. Only use R290-rated components—condenser motors, relays, and controls must meet safety requirements. We carry OEM-verified parts and the right spark-proof motors. R404A is still common in legacy walk-ins. When you replace condensers or parts, match the refrigerant and ensure TXV compatibility. Don’t mix oils—POE for 404A. Newer low-GWP blends are coming. When you spec a new condensing unit, ask us for models with forward compatibility and serviceable expansion valves.
Component picks I trust:
- Emerson/Copeland condensing units sized for your box load. For a mid-sized walk-in cooler, 1.5–3 HP Copeland units run $1,800–$3,600 depending on efficiency and controls. Danfoss TU/TEX2 TXVs matched to tonnage and refrigerant. Parker/Sporlan filter-driers (catch moisture and acid—replace every open service).
Safety note: If you’re not certified for hydrocarbon systems (R290), don’t open sealed systems. We’ll connect you with licensed techs and supply the parts. Our counter team knows the code requirements in our area and will flag anything that risks compliance.
Compared to standard plumbing supply houses, Plumbing Supply And More offers unmatched technical support, especially on emerging refrigerants and OEM-approved parts.
Walk-In Reliability: From Door Hardware to Evaporators—What Actually Extends Lifespan
Walk-ins live or die by door integrity and evaporator performance.
- Door closers and hinges: Kason door hardware is the industry standard. If your door slams, your gasket fails early and you lose efficiency. We stock Kason 1094 closers and complete hinge kits—$60–$180 and an hour to install. Strip curtains: Install them if your door’s propped during prep. They can reduce infiltration by 65% in high-traffic periods. Expect $120–$300 and a 30-minute install. Evaporator maintenance: Fan motors (9W–16W) and drain heaters (for freezers) fail more often than compressors. Keep spares. Replace in 30–90 minutes with proper lockout. Defrost strategies: Electric vs. off-cycle matters. We can set you up with Paragon timers or Dixell controllers to optimize defrost windows around your service flow.
We had a pizza concept with two walk-ins dropping temp during peak hours. We added strip curtains, tuned defrost schedules, and swapped a weak condenser fan. Result? Stable 35°F even during triple-door traffic and a noticeable uptick in dough consistency.
When Amazon or online-only outlets ship generic parts days late, our same-day delivery and emergency supply services keep your kitchen online. That’s the advantage of having a real partner, not just a cart.
Ice Machines: Pure Ice, Fewer Headaches—Filtration, Descale Cycles, and Spare Parts
Ice machines are unforgiving. A missed filter change or ignored scale alert turns into thin ice, slow harvest, and a Saturday callout.
- Filtration: Use the right flow and capacity. For Hoshizaki 600–900 lb/day, the Everpure EV9324-02 or Pentair equivalent is ideal. Replace at 6 months—mark the date on the cartridge. Descaling: Nickel-safe cleaner (Nu-Calgon) and a rinse timer set to manufacturer specs. Hoshizaki KM series like a 30–45 minute clean cycle monthly in hard water areas. Common spares: Inlet valves, water pumps, float switches/probes, and bin thermostats. Keep one of each on hand during peak season. Water inlet pressure: Keep 20–80 PSI. Pair with a pressure regulator if your building swings—our plumbing side will size it correctly.
A hotel account we serve neglected filtration to save $200 twice a year—they replaced a $600 pump and lost two days of service. Penny wise, pound foolish. We set them up with a filter subscription and they haven’t missed a beat.
While brands like Grainger and Ferguson carry basic ice parts, Plumbing Supply And More bundles filtration, OEM components, and real install guidance, so your team spends less time guessing and more time serving.
Plumbing Meets Refrigeration: Drainage, Condensate Pumps, and Electrical Coordination
Here’s where our roots as a full-service supply house matter. Cold equipment touches plumbing and electrical every time.
- Condensate drains: Use properly sized PVC with slope, P-traps where required, and air gaps. We stock Sch. 40 from our pvc supply house inventory and offer pre-cut kits for tight kitchens. Condensate pumps: Little Giant VCMA-20/40 units are reliable ($60–$120). Keep one spare during summer. Air gaps and backflow: Health departments check this. We carry ASSE-approved backflow devices and will match to your local health code. Dedicated circuits: Ice machines and reach-ins shouldn’t share loads that trip during rush. Our supply house electrical team will spec correct wire gauge, breakers, and disconnects.
This is where Plumbing Supply And More shines: one counter for refrigeration parts, plumbing traps, backflow, and electrical disconnects. You won’t find that synergy at the typical plumber supply house or an hvac supply house that doesn’t think about drains and backflow.
And yes, if you searched plumbing supply shop, plumbing supply store, or plumbing supply house near me, we’re the nearest plumbing supply with real knowledge across both trades.
Buying Smart: OEM vs. Aftermarket, Warranty, and When to Upgrade Instead of Repair
Not every repair is worth it. When do you replace?
- Reach-ins older than 12–15 years with R134a or R404A and repeated leaks: plan a replacement. New R290 units are efficient, quieter, and easier to service on the control side. Compressors: If your quoted replacement is more than 40–50% of the unit cost and the cabinet’s insulation is suspect, you’re throwing good money after bad. Aftermarket vs. OEM: Motors and controls can be high-quality aftermarket (Packard, MARS, Carel) when correctly matched. For ice machine internals, stick OEM—Hoshizaki and Manitowoc parts are engineered for tight tolerances.
We’ll price it straight: expect $2,200–$4,200 for a quality 2-door reach-in replacement, $1,800–$3,600 for a condensing unit swap, and $600–$1,200 for a compressor-only changeout (not including labor). We’ll also flag rebate opportunities and energy credits in our region.
When Home Depot, Lowe’s, and Restaurant Depot can’t provide spec sheets or brand-matched parts, Plumbing Supply And More brings exclusive partnerships, pro-grade inventory, and hands-on tech support that makes the difference between guessing and getting it right.

FAQ: Refrigeration Supply House Tips for Restaurant Owners
Q: What spare parts should every restaurant keep on-site for reach-ins and walk-ins? A: Keep a matched run/start capacitor, one condenser fan motor and blade, one evaporator fan motor, a universal contactor (coil voltage matched), a digital controller or thermostat compatible with your unit, and door gaskets. For ice machines, add an inlet valve, water pump, and a full filtration kit. We’ll build a custom bin labeled to your model numbers.
Q: How often should I clean coils and replace filters? A: Condenser coils monthly in greasy kitchens, quarterly otherwise. Evaporator coils twice a year. Ice machine filtration every 6 months (sooner in hard water). We carry Nu-Calgon cleaners, fin combs, and Everpure/Pentair filters, and we’ll set a reminder schedule for your team.
Q: Can I replace a R404A condensing unit with an R290 unit? A: Not on the same cabinet. R290 requires engineered, sealed systems with specific safety components. For legacy R404A walk-ins, replace like-for-like or consult us on an approved low-GWP alternative with matched TXVs and oil. We’ll verify code compliance and manufacturer guidance.
Q: Do I need OEM parts for my ice machine? A: For internal components (pumps, probes, boards), stick with OEM for Hoshizaki, Manitowoc, and Scotsman. For externals (line voltage contactors, some motors), high-quality matched aftermarket can be fine. We’ll advise based on model and warranty.
Q: What’s the fastest way to diagnose a “unit not cooling” call? A: Check power and breaker, verify condenser fan is running, inspect condenser coil cleanliness, confirm evaporator fans run with door switch held, and check the controller for setpoint and alarms. Then check the compressor (amps draw vs. nameplate) and look for frost patterns. Call us—we’ll talk you through it and deliver parts the same day.
Q: Do you support multi-site property managers with bulk purchasing? A: Absolutely. We create standardized parts lists across brands, set up bulk pricing, and stage inventory for scheduled PMs. Ask about contractor accounts, bulk discounts, and our delivery routes serving contractors throughout the region.
