Boiler and Furnace Replacement: Buyer Beware

In New York, Anyone with a Pipe Wrench Can Claim to be a Pro. That’s a Problem.

If you live in New York State and you think the guy working on your heating or cooling system is some kind of “licensed expert” because the state says so… you’ve been lied to.

Here is the dirty little secret that the “pro” with the rusty van and the pipe wrench doesn’t want you to know:

In the State of New York, there is absolutely NO specific licensing required to design or install a heating or cooling system.

The cities of Glens Falls and Saratoga Springs require plumbing licenses, but not heating. And outside of those city limits, you’re on your own for plumbers as well.

Read that again. It’s a loophole big enough to drive a truck through—and it’s leaving thousands of homeowners exposed to leaks, fire, carbon monoxide, and financial ruin.

“I don’t need no license.”

Right now, any guy with a set of tools can walk into your home, mess with your gas lines, botch your venting, and call himself a “professional.”

He doesn’t need to know the first thing about load calculations or Building Systems Science.

And frankly, it’s insane.

When your heat goes out in the dead of winter, you aren’t just fighting the cold.

You are navigating a shark-infested marketplace filled with unqualified laborers who are “learning” on your dime (and with your family’s safety).

They don’t understand the complexities of gas piping and venting. They couldn’t calculate a heat load if their lives depended on it.

Hiring the wrong contractor isn’t just a financial risk; it’s a safety risk.

The “Cheap” Trap (And How It Kills Your Wallet)

Look, I get it. We all love a bargain. But when it comes to your home’s mechanical systems, “cheap” is the most expensive thing you’ll ever buy.

Most people fall into what I call the “Band-Aid Cycle.”

Before you know it, you’ve paid for three repairs on a brand-new unit because the original design was garbage.

Here’s what’s actually at stake:

  • Safety (The Big One): We’re talking fire hazards and carbon monoxide leaks. You won’t smell it. You won’t see it. You just won’t wake up.
  • The Fuel Bleed: If your system is over-sized because it isn’t sized using real science, it will “short cycle”—turning on and off constantly. This murders your equipment and sends your fuel bills through the roof.
  • The “Band-Aid” Cycle: You hire the low-bid guy. He “swaps out the box.” It works for a week. Then it starts “short-cycling.” Then your gas bill jumps 30%. Then your pipes start banging like a drum set. You pay for repair after repair because the guy you hired never addressed the root cause: a botched design.
  • The Vanishing Act: These “fly-by-night” contractors are experts at one thing: disappearing the second things get complicated. You’re left in the cold—literally. And with no recourse.

David Sellers can often save you money by using the most up-to-date products and installation methods that the average heating contractor hasn’t heard of.

And by using his decades of experience with proper design principles, he will certainly save you money on your monthly fuel bills for the life of your heating and cooling system.

While you’re profiting by the savings your well-engineered heating system will provide, you’ll also be enjoying an unsurpassed level of comfort.

Like home movies?

I reduced to a 12 minute video my husband Dave Sellers’ mechanical life story (starting when he was 5), with a sampling of some of his projects. You can watch it here:

Master Mechanic Precision Since 1983

You shouldn’t have to be a mechanical engineer to get a safe, warm home.

At David Sellers Mechanical, we believe you deserve a contractor who treats your home with the same care they would treat their own.

Since 1983, David Sellers has been the man people call when everyone else fails.

David is know locally as the “Munchkin Magician.” Why? Because he has this “forensic” ability to fix complex, high-efficiency boilers that make other contractors start sweating.

David doesn’t just “swap out boxes.” He is a forensic mechanical expert.

While the other guys are guessing what size unit you need based on a “rule of thumb” (which is code for: I’m making this up), David uses Building Systems Science.

He analyzes your home’s unique airflow, your insulation, and your radiant needs. He treats your home’s mechanical system like a high-performance engine.
