Not financial advice (just a peek behind the curtain)

Chances are you’ve used a Snap-On wrench, installed a Trane unit, or ordered parts from Ferguson. But did you know a lot of these companies are publicly traded meaning you can track their performance, see how the market values them, and even invest?

I pulled together the brands contractors use every day and broke down how they’re doing on the stock market. It’s not about day trading but more about understanding which companies are driving growth in the home service industry and realizing the trades are going nowhere but up in the next coming years.

1. Trane Technologies (TT)

• What they do: Trane and American Standard HVAC systems heavy hitters in residential and commercial installs.

• Why you care: You or someone you know probably installs these units weekly.

• Stock move: Up 53% over the last year. Crushed earnings, raised outlook, and still climbing.

2. Lennox International (LII)

• What they do: Lennox systems, thermostats, and parts. A staple in HVAC.

• Why you care: Used in both installs and service these parts are everywhere.

• Stock move: Up 26%. Hit an all-time high in July 2025. Solid earnings. Steady operator.

3. Carrier Global (CARR)

• What they do: Maker of Carrier, Bryant, and Payne systems.

• Why you care: Massive brand in HVAC. Carrier’s been around since forever.

• Stock move: Up just 2%. Sales up thanks to acquisitions, but investors waiting to see results.

4. Johnson Controls (JCI)

• What they do: York HVAC, smart thermostats, commercial building automation.

• Why you care: York’s popular in residential, but JCI just sold that whole division to Bosch.

• Stock move: Up 40–50%. Investors liked the shift to focus on commercial systems.

5. Ferguson (FERG)

• What they do: Distributor of plumbing, HVAC, and waterworks supplies.

• Why you care: If you’ve ordered parts, you’ve probably dealt with Ferguson.

• Stock move: Up 25–30%. Bounced back hard after a dip. Strong U.S. demand driving growth.

6. Watsco Inc. (WSO)

• What they do: The biggest HVAC distributor in the U.S. Goodman, Rheem, Trane, and more.

• Why you care: This is where your parts guy gets his parts.

• Stock move: Flat (up 1–2%). Sales are solid, but the stock cooled off after a big run last year.

7. Home Depot (HD) & Lowe’s (LOW)

• What they do: Materials, tools, HVAC parts, rentals you know the deal.

• Why you care: You’ve definitely made a 7AM run to one of them.

• Stock move: HD up 2%, LOW up 7%. Slower growth now that the DIY boom is fading.

8. Stanley Black & Decker (SWK)

• What they do: DeWalt, Craftsman, Stanley tools power tools, storage, hardware.

• Why you care: Every tech has one of their tools in the truck.

• Stock move: Up 33%. Company’s been restructuring. Stock’s rebounding nicely.

9. Toro Co. (TTC)

• What they do: Mowers, irrigation, snow blowers landscaping and turf care pros know them well (I used to run a zero-turn back in the day)

• Why you care: You use this stuff, or your landscaping sub does.

• Stock move: Up 20%. Stable business, steady growth. Nothing flashy, but solid.

10. Snap-on Inc. (SNA)

• What they do: High-end tools and diagnostics. Big in auto, but used across HVAC and trades.

• Why you care: That Snap-on truck you see? Still a go-to for quality gear, and yes I know they are still pricey but people still love them.

• Stock move: Up 15–20%. Flat sales, but strong margins and loyal customer base keep it chugging.

11. ServiceTitan (TTAN)

• What they do: End-to-end software for home service companies scheduling, dispatch, estimates, payments, CRM.

• Why you care: Over 11,000+ contractors run their business on this.

• Stock move: IPO’d in late 2024. Popped 42% on day one. Still new, but growing fast.

What's This All Mean?

• The trades are investable. HVAC manufacturers, tool brands, and even your supply house are billion-dollar companies and many are doing very well, meaning you can too.

• Software’s here to stay. ServiceTitan’s IPO shows the tech side of the trades is getting real money behind it and so does the new wave of AI tools.

• The market watches us. When demand for HVAC and plumbing grows, these companies rise and Wall Street notices.

You don’t need to be a Wall Street analyst to follow this stuff. If you want to better understand the companies behind your parts, tools, and software watching their stock is a great way to keep tabs.
