Affiliate & Advertising Disclosure

How this site makes money

Plain version: this site earns money two ways, and neither one changes what the guides tell you.

1. Advertising. Google AdSense places ads on the pages. Advertisers pay for impressions and clicks; this site receives a share. The ads are chosen by Google’s system, not by me, and no advertiser gets a say in what a guide recommends.
2. Affiliate commissions. This site participates in the Amazon Associates program and in affiliate programs with parts retailers. When a reader clicks a product link and buys, the retailer pays this site a small commission. The price you pay is the same either way — the commission comes out of the retailer’s margin, not your pocket.

As an Amazon Associate the site earns from qualifying purchases.

What affiliate income does not buy

It does not buy a verdict, a ranking, or a recommendation. Parts and tools get recommended because they hold up in the field across brands and price points — the same part a tech would put on a truck. If a cheap generic works, the guide says so, even though the commission on it is smaller. If a part is a bad idea, the guide says that too, and there’s no link attached to a warning.

No manufacturer, retailer, or brand pays for placement in a guide, for a favorable review, or for a mention. There is no sponsored content on this site. If that ever changes, the page will say so at the top, in plain text.

Prices on this site

Prices shown in guides and calculators are ranges in 2026 US dollars, for parts and typical labor. They are built from real market numbers and labeled as ranges because that’s what they are — a furnace blower motor is not one price in St. Louis, and a water heater install is not one price in a basement with a narrow stairwell versus a garage with a straight shot.

Ranges also move. Copper goes up, refrigerant rules change, a manufacturer discontinues a board and the replacement costs more than the original. Prices on this site can be out of date the week after they’re written. The retailer’s price at the moment of purchase is the real one, and a local contractor’s written quote is the only number that binds anyone.

Links out

Links to retailers take you to a different company with its own prices, stock, return policy, and privacy policy. Nothing here controls that. Read the listing on the retailer’s site before you buy — check the model number against your equipment’s data plate, not just the photo.
