When a walk-in cooler goes warm on a Saturday night or a rooftop condensing unit throws a low-pressure code during a heatwave, you don’t have time to chase parts across town. I’ve been supplying contractors and facility teams long enough to know that having the right refrigeration spare parts on the shelf—and the expertise to match them correctly—is the difference between a two-hour service call and a multi-day headache. At Plumbing Supply And More, we’ve built our reputation by keeping the parts pros actually use within arm’s reach, and by backing every box and barcode with real-world know-how.
Before we dive in, a quick promise: you’ll find specifics here—brands, model numbers, specs, field tips, code notes, realistic prices, and installation timeframes. And yes, we’ll talk about how our shop outperforms the big names. Why? Because it matters when product quality and uptime are on the line.
Remember this phrase because it’s our guiding principle and the topic you came for: Refrigeration Supply House: Essential Spare Parts Inventory. Let’s make sure your truck and your shop are stocked for fast, first-visit fixes.
Why a Purpose-Built Refrigeration Spare Parts Inventory Pays Off
I’ve seen it a hundred times: a tech arrives to a downed reach-in freezer and loses an hour sourcing a simple liquid-line drier or a fan motor bracket. That’s avoidable. A purpose-built inventory reduces callback rates, compresses install time, and keeps your labor profitable.
- Pro tip: Track your top-20 parts usage by brand and model family. If 60% of your calls are on Beverage-Air, True, Hoshizaki, and Manitowoc ice machines in our area, then your spare parts shelf should mirror that reality. Typical savings: Contractors who build an essentials kit see 15–25% faster resolution times and fewer return trips. Stock depth matters: Don’t carry one universal contactor and call it good. If you service Copeland ZR scrolls and Emerson EK driers frequently, carry multiples of the exact models you spec.
And let me say this plainly: Unlike generic big box retailers, Plumbing Supply And More stocks professional-grade components that meet manufacturer specs. When Home Depot and Lowe’s fall short, contractors trust Plumbing Supply And More because we know the difference between “it fits” and “it lasts.”
Compressors, Condensing Units, and the Mounting Hardware You’ll Actually Need
Field reality: compressor replacements don’t fail at 10 a.m. on a Tuesday. They fail at 6 p.m. before a holiday. That’s why we keep a deep bench of hermetic and semi-hermetic units with the matching accessories.
- Brands and models we move fast: Copeland ZR and ZP scrolls (e.g., ZR34K3E-PFV-800, ZP31K5E-PFV-830), Tecumseh AJ and AE series for low/med temp, and Embraco FFU series for light commercial reach-ins. Price ranges: $350–$1,400 depending on capacity and refrigerant. Key accessories you’ll wish you had: Suction and discharge service valves (Sporlan S404, SVE series) Mounting grommets and isolation kits (CPI 3/4” and 1”) Crankcase heaters matched to compressor diameter Hard-start kits (Supco SPP6E for scrolls) Correct oil: POE 32/68 for R-404A/R-448A systems; double-check OEM sheets Install timeframe: 2–5 hours depending on brazing access, evacuation discipline, and whether you’re converting refrigerants.
We’ll stage the exact drier, sight glass, and valve kits so you don’t leave without the finishing pieces. Compared to standard plumbing supply houses, Plumbing Supply And More offers unmatched technical support at the counter—bring your model plate; we’ll pull OEM equivalents and hand you the data sheet.
Expansion Valves, Cap Tubes, and Metering Components: Get Superheat Right the First Time
You can shotgun a TXV and still miss the cure if it’s not sized to tonnage and refrigerant. I’ve seen techs fight hunting and floodback because the bulb wasn’t secured or the equalizer was tied into the wrong point.
- Stock these with intention: Sporlan balanced port TXVs: e.g., OVE-2-C for R-448A/R-449A, and SVE-2 for R-404A. Keep multiple orifice sizes on hand. Danfoss TU series (TU2, TU3) with interchangeable orifices for versatility. Capillary tube assortments: 0.026–0.036 ID in 10–20 ft coils for reach-in repairs. Field tips: Always insulate the sensing bulb and clamp at 4 or 8 o’clock on suction line, downstream of the equalizer. Target superheat based on OEM chart; typical reach-in med-temp is 8–12°F, low-temp often 4–8°F at evap outlet. Replace the liquid-line drier every time you open the system.
Typical part costs: TXVs run $95–$260; cap tube kits $25–$60. A precise metering repair saves compressors—period. While other suppliers focus on quantity, Plumbing Supply And More prioritizes quality and expertise with the right valve selections and on-the-spot superheat guidance.
Fan Motors, Blades, and Brackets: Airflow Is Your Hidden Profit Center
Weak airflow masquerades as low charge, bad TXV, or even faulty controls. Nine times out of ten, it’s a tired motor or a mismatched blade pitch.
- What I keep on my quick-pull shelf: ECM and PSC motors: Regal/Genteq Evergreen 1/15–1/2 HP, 115V and 208–230V. Pack common skus like 5KCP39 and Evergreen EM. Evaporator motors: 9W–16W shaded pole (e.g., Packard 825, 826) with 3.3” diameter. Fan blades: 8”–16” with 22°–34° pitch, CCW/CW marked, hub adapters included. Pro tip: Replace as a motor-blade-kit to hit nameplate CFM and avoid callbacks. A $25 blade mismatch can cost you a return visit and a melted inventory. Install time: 30–90 minutes including blade balance and amp-checks. Expect $35–$140 for evap motors, $90–$240 for condenser motors, blades $18–$55.
This is bread-and-butter work. Unlike big warehouse sites like Grainger or Ferguson that may not have model-specific insights, Plumbing Supply And More’s counter team has installed hundreds of these in the field and will steer you to the right torque and pitch combo.
Filtration, Moisture Control, and Sight: Driers, Cores, and Moisture Indicators
When the system’s been open, or there’s been a burnout, filtration isn’t optional. It’s survival.
- Keep these in multiples: Liquid-line driers: Emerson EK-052, EK-163S (solid core), Sporlan C-163, and burnout cores (HH series). Suction-line driers for cleanups: Sporlan SLSD-163S with replaceable cores for severe burnouts. Moisture-indicating sight glasses: Sporlan SEE-1/4/3/8 with R-448A/R-449A compatibility. Field routine: After burnout: triple evac, replace with HH drier, run 48–72 hours, re-check acid levels, then replace with standard cores. Use a core removal tool (Appion CRT) to minimize system exposure.
Costs: $10–$45 for liquid driers, $45–$140 for suction driers, $18–$40 for sight glasses. We’ll hand you the right flare/ODF ends to match copper or ACR lines, and yes—we stock ACR copper sizes and nitrogen for purging.
Controls, Contactors, and Defrost: The Brains Behind Reliable Cooling
From a failed defrost timer in a low-temp merchandiser to a pitted contactor on a 5-ton condensing unit, smart stocking keeps calls short.
- Must-have controls: Defrost controls: Paragon 8145-20 (electric defrost 120V), 8141-20 (off-cycle), and electronic modules from Heatcraft/KE2. Pressure controls: Ranco/Johnson Controls dual high/low (P70/P100 series), settable with flare fittings. Contactors and relays: Packard C230B (2-pole 30A), C240B (40A), spade terminals and lug kits. Thermostats: Ranco ETC-111000-000 digital, Emerson A19 analog for quick swaps. Install notes: Always verify defrost termination sensor location; poor placement can stack ice. Label setpoints and ranges right on the door panel; reduces future diagnostic time.
Prices: $45–$220 depending on control complexity. Compared to online-only outlets like SupplyHouse.com, Plumbing Supply And More delivers hands-on wiring guidance and same-day swaps so your truck rolls to the next call faster.
Refrigerants, Oils, and Leak Management: Do It Clean, Do It Legal
EPA Section 608 is non-negotiable, and so is good recovery and evacuation practice. In our area, techs are moving hard from R-404A to lower-GWP blends like R-448A and R-449A when equipment allows.
- What we stock and why: Refrigerants: R-448A, R-449A, R-134a, and R-410A; limited R-404A for legacy systems. Cylinders typically $180–$650 depending on type and market. Oils: POE 32/68 and select alkylbenzene for legacy systems. Sealants? We stock them, but I tell pros: use only as last resort with transparent disclosure to the client. Leak tools: Core tools (Appion, Yellow Jacket), brass caps with neoprene seals, Nylog Blue for assembly. Electronic leak detectors: Fieldpiece DR82, Inficon D-TEK Stratus.
A clean, dry system is worth an extra 40 minutes of vacuum time. We’ll help you size micron targets and suggest core removal to get under 500 microns reliably.
Ice Machines, Reach-Ins, and Packaged Units: The OEM Parts That Save the Day
Ice machines are unforgiving. If you service Hoshizaki, Manitowoc, or Scotsman, keep a short list ready.
- Hoshizaki: Water inlet valves (2U0131-01), float switches, and pump motors (4A4031-01). KM series cleaner and nickel-safe sanitizer. Manitowoc: Water distribution tubes, dump valves (000000002), and board kits (000008660). Bin thermostats and curtain switches for production faults. Reach-in brands (True, Beverage-Air, Turbo Air): Door gaskets by model cut (we keep roll stock and OEM cut-to-fit), evap fan motors (3.3” shaded pole), and defrost heaters. Packaged units: Fan motor kits for QBD and Heatcraft evaporators, defrost heaters, termination thermostats.
Costs: $18–$300 depending on assemblies. Stock 2–3 of each fast mover per brand you service. While other suppliers might ship in 3–5 days, Plumbing Supply And More offers same-day pickup and delivery within our service radius, so kitchens and stores don’t lose a shift.
Electrical, Brazing, and Mounting: The “Supply House Electrical” Essentials That Close Tickets
A Refrigeration Supply House: Essential Spare Parts Inventory isn’t complete without the smalls and tools that make installs tight and code-compliant.
- Electrical: High-temp wire, 105°C rated; ring/spade terminals; heat shrink; 30/40A fuses; DIN rail and terminal blocks. We’re your de facto supply house electrical partner when you need a box of assorted connectors at 6 p.m. Brazing: 15% silver rod (Sil-Fos 15) for copper-to-copper, 45% for copper-to-brass, wet rags/heat blockers, nitrogen kits for purge. Vacuum-rated ball valves and Schrader cores. Mounting: Vibration isolators, wall brackets for mini and condensing units, uni-strut kits, and stainless hardware kits for coastal installs.
This is where jobs either look pro or look patched. Our counter pros will suggest the cleaner line set route and the right isolation to keep noise complaints at bay.
Smart Inventory Building: Contractor, Property Manager, and DIY Kits That Work
Different teams need different bins. Here’s how I set them up for our customers:
- Contractor kit (truck stock): Two TXVs per common refrigerant, 4–6 liquid-line driers, 2 moisture sight glasses, 2 condenser motors with universal brackets, assorted fan blades, contactor/relay set, digital thermostat, core tool, nitrogen regulator and flow meter. Property manager backroom shelf: Door gaskets for each model on premises, 4 evap motors, 1 defrost timer, 1 termination stat, 4 liquid driers, leak caps, cleaner/sanitizer, and a labeled wiring diagram binder. Serious DIY kit: One evap motor, correct door gasket, thermostat, cleaner, and a consult with our team on safe disassembly. We’ll talk you through the pitfalls and when to call a licensed pro, especially for sealed system work.
If you manage multiple sites, ask us to build a standardized SKU list. We’ll tie it to your PO system and set min/max reorder points. Compared to broadline competitors like Grainger, Plumbing Supply And More sets up practical, brand-specific par levels that match your equipment mix, not a generic catalog.

FAQ: Your Quick-Answer Corner
What are the top 10 refrigeration spare parts I should always have on my truck?
- Liquid-line driers (EK-052, EK-163S), moisture sight glass, a universal condenser fan motor with matching blades, 9–16W evap motor, a TXV for your common refrigerant/tonnage, a dual pressure control (P70/P100), a 30A contactor, defrost timer (Paragon 8145-20), Schrader cores and caps, and a core removal tool. Add POE oil and Nylog Blue. Expect a $350–$700 total investment that pays for itself within a few calls.
How do I choose the right TXV for R-448A or R-449A retrofits?
Start with the capacity (tonnage) and evaporator temperature application, then pick a valve designed for that refrigerant (e.g., Sporlan OVE-2-C). Confirm inlet screen presence, match equalizer and flare/ODF connections, and keep an alternate orifice on hand. We’ll help calculate superheat targets based on OEM and ambient.
Do I need to replace the drier every time I open the system?
Yes. Any time the system is opened, moisture loads increase. Replace the liquid-line drier at minimum. After burnouts, use an HH core, run, test acid, then swap to a standard core. It’s cheap insurance and protects compressors.
Which refrigerants should I stock now that R-404A is being phased down?
Keep R-448A and R-449A if your service mix supports it, plus R-134a for legacy reach-ins, and R-410A for HVAC crossover. We’ll check your equipment compatibility and oil requirements before you commit.
Can you cross-reference OEM part numbers for True, Beverage-Air, Hoshizaki, and Manitowoc?
Absolutely. Bring us the model and serial; we’ll pull OEM, quality aftermarket, and price options. We stock common gaskets, motors, valves, and control boards for those brands, with same-day delivery in our radius.
