When Was Your Last Elevator Quality Check? A 5-Step Walkthrough for Facility Managers

Who This Walkthrough Is For

This is for the facility manager or maintenance director who's staring at a stack of service proposals or spare parts quotes and needs a repeatable way to separate the good from the risky. I do this for a living — I review every major maintenance contract and parts delivery for a mid-market commercial real estate portfolio before it reaches our buildings. Over the years, I've rejected roughly 18% of first-time deliveries in 2024 due to spec mismatches or quality issues.

Here's a 5-step checklist I use. It's not fancy. But it catches the stuff that billing won't.

Step 1: Verify the Parts List Against Your Specific Unit

This sounds obvious, but this is where 40% of our issues start. I once rejected a batch of 120 "compatible" guide shoes intended for an Otis Gen2 system because the vendor had swapped the rail profile spec. The rail was off by 3mm. Normal tolerance is +/- 1mm. The vendor argued it was "within industry standard." It wasn't. We rejected the batch, and they redid it at their cost.

Your check: Don't just ask for a quote. Get a line-item breakdown that includes the OEM part number or the equivalent spec (like rail gauge, load rating, and material composition). Cross-check it with your unit's service manual. If the quote says "Otis spare parts" but doesn't list a model, that's a red flag.

Side note: This worked for us because we have a standard portfolio. If you're managing a mixed-use building with custom cabs and 20-year-old controllers, your verification process needs to be way more thorough. Your mileage may vary.

Step 2: Don't Just Ask "How Much?" — Ask "How Long Has It Been Sitting?"

Here's the thing: a spare part at a 30% discount might be a great deal. Or it might be a part that's been sitting on a shelf for 18 months. For electronic components like door operator boards or drive controllers, long-term storage can mean corrosion on contacts or firmware that's two versions behind.

Your check: When you get a quote for an AC repair part for an Otis unit (say, an inverter assembly), ask for the manufacturing date code on the part. If it's more than 6 months old for electronics, ask for a price adjustment or a component-level test report. Honestly, I started doing this after we installed an old board that failed in 3 months. The $200 savings turned into a $1,500 service call and a pissed-off tenant.

Step 3: Check the Maintenance Proposal for "Weasel Clauses"

I read a lot of maintenance contracts. The biggest trap isn't the price per month — it's the list of excluded items. A basic "oil and grease" contract looks cheap until the controller needs a firmware update or a brake requires adjustment.

Your check: Look for these exact phrases in the fine print: "standard adjustments," "normal wear and tear," or "at technician's discretion." Ask for a specific list of what's included in the baseline. For example, does the contract cover the labor to replace a worn out roller guide? Or is that a separate billable repair? Real talk: the lowest quote I saw in Q1 2024 was cheap because it covered almost nothing. We passed.

Step 4: Run a Quick "What If" on Downtime Cost

Most facility managers calculate cost by the sticker price of the service or part. But here's the calculation I use. For a single commercial elevator in a mid-rise office building, a 4-hour downtime during business hours can easily cost $2,000 to $5,000 in lost tenant productivity and branding damage. Suddenly, that "budget" service that saves $800 a year but responds in 8 hours isn't a bargain — it's a risk.

Your check: Ask the proposed service provider for their average response time to an emergency call and their on-site time to resolution for common issues (like a stuck door or a fault code). If they can't give you a straight answer, that's a data point. I've rejected two vendors this year based on vague response time commitments. The upside of a faster response was way bigger than the risk of saving a few hundred bucks.

Step 5: Verify the Safety Compliance Paperwork Before Signing

A lot of people skip this. Don't. Look, I assumed once that all service providers carried the same liability insurance and adhered to the same code updates. Didn't verify. Turned out one of our subcontractors was using a safety circuit bypass that violated a local code update from 2023. Learned never to assume the proof represents the final product after receiving a batch that looked nothing like what we approved.

Your check: Ask for a current certificate of insurance (minimum $1M general liability for most commercial buildings), and ask which version of ASME A17.1 / CSA B44 they are working to. If they can't articulate the code cycle, they're not staying current.

Final Thoughts: What You'll Catch

Following these steps won't guarantee zero problems — that's not a promise anyone can make. But it will cut down the 3 biggest headaches I've dealt with in 4 years: wrong parts, hidden exclusions, and liability gaps.

One last thing: if you're dealing with a high-volume property or a luxury residential building, you'll want to add a step for aesthetic consistency (cab interior finishes, floor leveling tolerances). That's beyond this checklist, but it's worth keeping in mind when you're specifying for brands like Otis where public perception of "safety and reliability" is tied to how smooth the ride looks and feels.

Period.
