From The Investigations

What This Information Is Worth

★★★★★

"Three contractors quoted $14,000 to $19,000 for a full replacement. Three weeks of research later: a variable-speed retrofit on his existing ductwork for $6,200."

Richard, 72 · Houston, TX · Part 4: The Hybrid Retrofit

Saved $12,800

★★★★★

"He bought the $30 'allergen defense' filters and changed them on schedule. Two years later: frozen coil, dead blower motor, a $2,400 bill caused by the filter."

David's system · Part 5: The MERV Lie

$2,400 repair, preventable for $5

★★★★★

"26 years running his own shop. Gets called twice a week to install units homeowners bought online. His answer is always no, and his blacklist is in this book."

Marcus · Phoenix, AZ · Part 3: The Blacklist

7 brands to avoid

★★★★★

"His evaporator coil looked like Swiss cheese after six years. The tech's verdict: 'this is normal now.' The coil chapter explains why, and which designs don't rot."

Arizona homeowner · Part 1: The Coil Downgrade

Avoids a $5,000 repeat

★★★★★

"A $99 tune-up, 22 minutes, 15 scary photos, and a financing tablet. One question ended the entire performance: 'are you paid commission?'"

The tune-up script · Part 7: Scam Defense

$10,000 pitch declined

Cases documented in our published investigations. The full stories and numbers are in the manual.

How we source this: every brand claim, price, and repair figure is cross-checked against documented class-action filings, EPA regulatory records, Consumer Reports reliability data, and field reports from independent, non-sponsored HVAC technicians, not manufacturer marketing.

PART 3

The Blacklist

Seven names experienced technicians refuse to install, from "the fountains" to orphan inverter imports.

PART 4

The Six Loopholes

Hybrid retrofit, downsize & dehumidify, incentive stacking, the $300 insurance policy, and the supply-house recon.

PART 5

Filters & Airflow

The MERV lie, what to actually buy for $5, and the media-cabinet upgrade that gives clean air without the damage.

PART 6

The Refrigerant Game

Four gases, four bans, one pattern, and how to never panic-buy a system over a phase-out headline.

PART 7

Scam Defense

The $99 tune-up decoded minute by minute, three fake diagnoses, and the one question that ends the game.

Before You Ask

Questions, Answered

Does this apply to my system: old unit, new build, heat pump?+

Yes. The manual covers both sides: keeping your current system alive (filters, surge protection, refrigerant decisions, scam defense) and buying right when it finally dies (the lifetime list, the blacklist, sizing, retrofits). Furnaces, ACs, and heat pumps are all covered. US market focus.

How fast does it pay for itself?+

Usually on the first service visit. Declining one mispriced capacitor swap covers the book several times over, and the filter chapter alone saves $220+ a year. The big plays, like a retrofit instead of a full replacement or a second opinion on a red tag, are four-figure swings.

I know nothing about HVAC. Will I understand it?+

It's written for exactly you. No tools and no technical background needed. Every entry is a real situation, a fix, and the exact words to say to a technician. That doesn't mean it's simplified: every claim behind it is still cross-checked against EPA filings, class-action records, and licensed-technician reports. You just don't have to read those yourself.

I'm in my 60s or 70s. Is this still for me?+

Yes. If anything, this is who it was written for. No tools, no crawling in the attic, nothing physical at all. Every entry is a situation and the exact words to say to a technician, printed large enough to hold at the door. If you can read a paragraph and ask a question out loud, you can use this book.

I'm handy and research everything. Anything new for me?+

The parts most people never find: the supply-house recon method for finding honest techs, the Bosch 24V retrofit loophole, capacitor tolerance math, and the refrigerant patent cycle. It's the stuff that lives in technician forums, organized.

What format is it? How do I get it?+

Instant download, 42-page PDF, readable on any device and printable (the checklists are made for it). Secure checkout via Paddle; your download page opens immediately after purchase, plus a receipt by email.

What's the refund policy?+

14 days, full refund, no questions asked. If the manual doesn't earn its price, reply to your receipt email and say so. No forms, no explanation required. Full policy here.
