Welcome to the Lounge.
Pull up a chair. I’ve been in HVAC since 1999. Let me tell you what I’ve learned — and what I wish I’d known sooner.
What We Talk About Here
No brand politics. No sales pitches. Just two things that matter no matter whose equipment you’re installing:
- Installation pitfall avoidance — the mistakes that cost you time, money, and reputation. I’ve made most of them so you don’t have to.
- System energy optimization — how to make any HVAC system run smarter and cheaper, from centrifugal chillers to residential multi-split units.
Everything here is from the field. Not a textbook. Not a manufacturer’s brochure. Real jobs, real problems, real solutions.
Who Am I?
17 years at Gree Electric. Then 8 years running my own projects — big and small. I’ve seen this industry from every angle. Now I share what I know, for free, because I believe this knowledge should belong to the people doing the work — not the people selling the equipment.
