As temperatures start to drop in Central Indiana, many families are scheduling their annual furnace inspections to get ready for the long winter ahead. Unfortunately, this is also the time of year when one of the most common—and costly—HVAC scams shows up at your doorstep.
We’re talking about the infamous “cracked heat exchanger” scam. Let’s break down what it is, how to spot it, and what you can do to protect your home and your wallet.
What Is the “Cracked Heat Exchanger” Scam?
Your furnace’s heat exchanger is a critical part of the system. It transfers heat safely into your home while keeping dangerous gases like carbon monoxide out of your air supply.
When a heat exchanger truly cracks, it’s a serious issue that needs to be addressed. But some dishonest companies use this fear to push homeowners into buying a brand-new furnace—even when there’s nothing wrong.
They’ll claim to see a crack but refuse to show it to you, claim it’s out of view, or they’ll use vague language about “potential danger” without any proof. Their goal? To pressure you into an expensive replacement you may not need.
Signs You’re Dealing With a Scam
Here are red flags to watch for during a furnace inspection:
- The technician won’t physically show you a verifiable crack.
- You’re pressured into making a quick decision.
- Repair options aren’t offered—only full replacement.
- The technician uses scare tactics instead of straightforward explanations.
If you encounter any of these, it’s time to slow down and get a furnace replacement second opinion.
How to Protect Yourself
The best defense against furnace scams is knowledge and caution. Here’s what we recommend:
- Ask for clear visual proof of any crack (photos, videos, or an in-person demonstration).
- Don’t agree to expensive work on the spot—take time to review.
- Research the company: check reviews and whether they’re locally owned or part of a corporate chain.
- Always seek a second opinion before replacing a furnacen or another component of a major household system.
At Absolute Comfort, we provide second opinions at no cost, because peace of mind should never come with pressure.
Why Indiana Homeowners Are Especially Vulnerable
In recent years, many HVAC companies around Indianapolis, Greenwood, and Franklin have been bought out by large corporations and private equity firms. Their technicians are often trained to sell rather than serve, creating a perfect environment for scams.
That’s why choosing a trusted, family-owned company matters more than ever here in Central Indiana.
What an Honest Furnace Inspection Looks Like
A reliable technician will:
- Explain findings in clear, everyday language.
- Show you the problem directly.
- Offer multiple solutions, including repair if possible.
- Never pressure you into a same-day decision.
That’s the Absolute Comfort difference—our inspections are about your safety and comfort, not meeting sales quotas.
The Bottom Line
The cracked heat exchanger scam is one of the biggest furnace scams in Indiana, but you don’t have to fall for it. By asking for proof, doing your homework, and seeking a second opinion, you’ll stay in control of your home comfort and your budget.
