Small Projects, Big Mistakes: Lessons Learned from Brita, Mini Splits, and Smart Lighting

I've been handling water filtration, HVAC, and lighting installation orders for 12 years. I've personally made (and documented) 11 significant mistakes, totaling roughly $30,000 in wasted budget. Am I proud of that? No. But now I maintain our team's pre-installation checklist, and every item on it exists because of a failure.

So let me get to the point: Small projects don't deserve small attention. In fact, my most expensive mistakes all came from dismissing a job as "too tiny to matter."

The Brita Filter That I Almost Got Wrong

A customer once asked for a "Brita Pro Platinum Water Softener." I paused. Brita doesn't make a softener, but I knew what they probably wanted: a Brita Pro Platinum filter jug. (The word "softener" was the first red flag—I should have stopped right there and asked clarifying questions.)

Instead, I almost skipped the detail and sold them the base model. Glad I caught that. But my mistake was different: I didn't ask about their water quality. I loaded the order with standard Maxtra filters and called it done.

Two weeks later, they were back. The cartridges looked gross, the water flow slowed down, and they were already buying replacements. I'd ignored the fact that their supply came from a private well with high iron sediment.

The fix was easy: a Brita Elite replacement water filter designed to reduce more impurities like lead, chlorine, and other common contaminants. But the damage was done—a refund, a replacement, and a lesson learned.

Here's the thing: even a "simple" Brita order is a decision about water chemistry. The smallest filter choice can affect the whole household. Even after choosing the Elite filter, I kept second-guessing. What if it still didn't work with their well? The two days until they confirmed the water tasted better were stressful.

That experience introduced the first rule on our checklist: Never skip water-quality assessment for any filter order, regardless of product size.

Mini Split Efficiency Is a Calculation, Not a Suggestion

Then there was the mini split job. A single sunroom, about 120 square feet. I thought the biggest unit I had would be perfect. "Blow cold fast," I told myself. I hit "confirm" on the order and immediately wondered if I'd sized it right. Didn't relax until the install... which turned out to be the problem.

The customer called three weeks later. The unit cooled the room quickly but rarely shut off. The energy bill had nearly doubled. Mini split efficiency isn't just a label—it's the relationship between capacity, room volume, insulation, even sun exposure. An oversized unit short-cycles, dehumidifies poorly, and chews through electricity.

I had to redo the system with a smaller, correctly matched unit. That cost $1,100 in labor and the price of the new unit. The old one went to my own garage (where, honestly, it's still too big).

Now every mini split quote includes a load calculation. Every single one. Even for a closet.

Savant Smart Lighting: Even One Room Requires a System

I expected Savant smart lighting to be straightforward. One room, four switches. How hard could that be?

Turns out, very hard. I grabbed the first power modules I thought were compatible and started wiring. By the end of day two, the lights were on a 3-second delay and the app kept dropping the room.

Savant's ecosystem requires specific module-load ratings. I'd used a generic substitute, which worked until it didn't. The fix meant swapping the modules, re-pairing everything, and apologizing to a very patient client.

That job cost me $800 in extra parts and a weekend. All because I assumed small scope = simple execution. The takeaway: technology is technology, and "small" doesn't skip the planning stage.

How Does a Dehumidifier Work in a Room? (I Finally Had to Explain It)

A client asked me one day: how does a dehumidifier work in a room? I gave a rambling answer about fans and condensation, then recommended a commercial-grade unit "to be safe."

Mistake. The unit sounded like a jet engine in their bedroom, and it actually left the room feeling clammy, because the oversized compressor was cycling too fast.

A dehumidifier works by pulling humid air over cold coils, condensing water into a tank, then blowing dry air back out. The right size depends on the room's square footage and starting humidity. Not "more is better."

I refunded the machine and installed the correct-sized residential unit. The best part of fixing that: the client's words—"I finally understand how it works." That's when I learned that explaining the principle is part of the installation.

"It's Only a Small Job"—The Most Expensive Sentence in Contracting

You might be thinking: "Great, a contractor with accountability issues. What does this have to do with me?"

Here's what it has to do with you: the same care that determines whether you get a product that works or a project that haunts you. When you treat a small upgrade as a minor purchase, you're making yourself vulnerable to the same shortcut thinking I had.

Look, I get it—if you're just buying a filter jug or a smart switch, it's tempting to click "add to cart" and forget it. But ask the right questions before you buy. Measure the room for that mini split. Read the specs on the filter. Understand how your new dehumidifier actually works. These are five-minute steps that save thousands and a lot of regret.

And if you're a homeowner with a small office? Take it from someone who's lost sleep over these choices: even a $50 Brita filter deserves a little research. The vendors who took my $200 orders seriously when I was starting out are the ones I trust with $20,000 today.

Small doesn't mean unimportant. It means potential.

So here's my final thought, with all the scars to back it up: The size of the project doesn't change the standard of care. The details are the project. Period.
