Commercial Appliance Specs: A 7-Step Checklist My Team Uses for LG B2B Purchases

If you're outfitting a new hotel, a row of apartment units, or a shared laundry facility, the appliance spec sheet you send to your distributor is basically a contract. Get it wrong, and you're dealing with installation delays, tenant complaints, or—worst case—voided warranties. I've been on both sides of that paperwork. Here's the checklist I run through before signing off on any commercial LG order.

(A quick note: This is based on what we've learned from roughly 50 projects over the last four years—everything from 10-unit buildings to a 200-key boutique hotel. It's not exhaustive, but it'll catch the mistakes I've made more than once.)

This Checklist is For You If...

• You're a property manager outfitting new units
• You're a contractor specifying appliances for a multi-family build
• You're a hospitality buyer stocking a new property's kitchens and laundry rooms
• You're a small business owner upgrading your rental's appliances for the first time

If that sounds like you, here are the 7 steps we follow.

Step 1: Start With the Power & Ventilation, Not Just the Appliance

The mistake most people make: They pick a model they like, then try to fit the building around it.

The fix: Start with what your building can handle. For LG over-the-range microwaves, for example, you need to confirm the overhead cabinet depth and the electrical specs. A standard OTR microwave pulls about 15 amps on a dedicated 120V circuit. If you're retrofitting, that might mean a new run from the panel—which adds cost and time.

I've seen a spec fail because someone ordered a beautiful LG smart oven that required a 40-amp circuit, but the kitchen only had a 30-amp line installed. That was a $2,500 redo and a two-week delay. Now, every spec starts with a simple electrical and footprint check.

Quick Checkpoint:

• Dedicated circuit? (No sharing with the refrigerator or dishwasher)
• Vent clearance? (Over-the-range models need 66-72 inches from floor to cabinet)

Step 2: Measure the Opening—Twice—and Remember the Stacking Kits

This sounds obvious, but it's the most common spec error I catch. For an LG tower washer and dryer (the WashTower), the dimensions are specific. That unit is roughly 74.5 inches high and 27 inches wide. But here's the part people forget: the stacking kit. If you're using the WashTower, it has a built-in stacking system. If you're ordering separate front-load units, you need a separate stacking bracket.

I had a project where we specified the dimensions perfectly—height, width, depth—and the units got delivered. But no one had ordered the stacking kit. The installer couldn't stack them safely. We had to order the kit overnight and pay for an extra trip. On a 50-unit building, that added up to a significant cost and a lot of frustration.

Key Measurement Anchor:

• Standard washing machine width: Most full-size washers are 27 inches wide. Front-loaders are almost always 27 inches. Top-loaders can vary from 27 to 29 inches.
• Stacked depth: Measure from the wall to the front of the machine with the door open. You need at least 24 inches of clearance for the door swing.

Step 3: Check the Filter Specs for Food Service

If you're buying an LG oven or cooktop for a commercial kitchen—or even a shared amenity kitchen—check the hood requirements. Many built-in ovens, like a JennAir built-in oven (which is a related high-end spec), have specific clearance requirements to cabinets.

But for B2B, the issue is often about water filters. If you're installing an LG refrigerator with an ice maker and water dispenser (like in a break room or a guest suite), the water filter is a consumable. You need to plan for replacement schedules. The LT1000P or similar filters need to be changed every 6 months. On a 30-unit building, that's 60 filters a year. If you don't plan for that, the ice maker gets clogged, and guests complain.

Honestly, I'm not 100% sure why some spec sheets omit this, but it's very common. My best guess is that the person writing the spec isn't thinking about the year-two operational cost.

Important Filter Note:

The LT1000P filter is compatible with many LG refrigerators, but always verify the part number against the appliance's manual. Using the wrong filter can reduce water pressure or void the warranty.

Step 4: Don't Assume Everyone Needs the Same AC

For multi-unit buildings, you might be tempted to spec the LG air conditioner based on square footage alone. But in commercial settings—especially older buildings—you need to consider the heat load from other appliances and insulation quality. I've seen an infrared electric heater used as a supplement in a unit that had poor HVAC ducting, which actually solved the comfort issue at a lower cost than upgrading the main AC unit. But it also changed the electrical load calculation.

If you're doing a bulk purchase, always do a load calculation for each unit type, not just a one-size-fits-all spec. We once ordered 60 of the same LG AC units for a building, only to find that the top floor units needed a 15% higher BTU rating because of the roof heat gain. We had to replace 10 units at a premium cost.

Step 5: Verify the Warranty Terms for Commercial Use

This is a big one. Many residential LG appliances have a standard 1-year warranty. But if you're buying for a hotel or a rental property, the use case might void the warranty if it's considered 'commercial.' You need to either buy the commercial-grade version of the appliance, or negotiate a commercial warranty add-on through your distributor.

The good news is that LG has a specific commercial laundry program with extended warranties and heavy-duty components. I've gone back and forth between saving 15% on a residential unit with a standard warranty versus paying more for the commercial line. For high-turnover rentals or hospitality, the commercial line is almost always the right call. The ROI comes from fewer service calls.

Service Network Check:

• Does the distributor have a dedicated service team for commercial clients?
• What is the response time for a warranty repair? (48 hours vs. 2 weeks makes a big difference)

Step 6: Test the Smart Features in Your Context

LG's ThinQ platform is a strong selling point. It lets you monitor and control appliances remotely. For a property manager, this can be great for energy management or notifying when a laundry cycle is done. But the smart features require a stable Wi-Fi connection.

In a recent project, we installed smart LG washers and dryers in a basement laundry room. The Wi-Fi signal was weak due to concrete walls. The smart features were basically useless. We had to install a mesh network booster at our cost. The lesson: test the Wi-Fi signal at the exact installation location.

Part of me prefers the simplicity of non-connected units for commercial settings. Another part knows that energy management and remote diagnostics can save money. Right now, I compromise by specifying smart models but ensuring the building has infrastructure to support them.

Step 7: Plan the Delivery and Installation Window

For a large order, delivery logistics are as important as the spec. LG products are generally available, but some models (like the popular tower washer/dryer combos) can have lead times of 3-4 weeks if demand is high.

My team now requires all orders to include a delivery window agreement: the supplier must confirm a delivery date within 5 business days of the order, with penalties for delays longer than 1 week. This came from a project where the appliances arrived 3 weeks late, but the construction crew was already gone. We had to pay for a second crew to install them.

If you're a small client ordering just a handful of units, this is where you might feel overlooked. I've had vendors who didn't respond to my schedule requests because the order was small. My advice: find a distributor who treats a $2,000 order with the same urgency as a $20,000 order. They exist.

Common Mistakes & Things I'd Do Differently

If I could go back and redo my first few commercial appliance specs, I'd have:

1. Included a 'plan for consumables' section—water filters, air filters, drain hoses. You need to budget for these from day one.
2. Not trusted the 'standard' delivery date. Always add a 20% buffer to the timeline.
3. Spent more time on installation training. A great appliance is only as good as its installation. Ensure your contractor knows the specific requirements for LG's door reversals (for washers) or anti-tip brackets (for ranges).

Take this with a grain of salt, but the biggest improvement we saw in our project success rate—about a 30% reduction in post-installation issues—came from simply having a single point of contact at the distributor who handled all the spec questions for us.
