Yes, Bryan, I'll run through that. And let's step back at a high level and look at our segment income margins at the SPX level first because we've been applying our business system across the enterprise, and we think it's made a positive impact. If you just step back, 2020, our segment income margins were 15.4%, 2021, they are 16.4%. Last year, we had a lot of challenges with supply chain, labor, PPV, there was 17.1%. We thought that 17.1% was a little bit lower than what it should have been. And where we sit today is 20% at segment income margin. So steady increase, basically 460 basis points in 3 years. So what that says to me is I do believe in our business system, I think it's working, and I do believe our strategy is sound. So if we drill down into HVAC specifically, the way I think about the business is, historically, we've thought about that as a 15% to 16% business. Last year, as we talked about we had a lot of headwinds. And last year, we ended up at around 14.8%, right under 15%. But again, we think a lot of the improvements that we had made in lean and the plant layout some of the investments in automation equipment was masked by some of these headwinds. So if you look at where 2022 ended to where we are in 2023. A couple of things have driven improvement. One is operating leverage. We're having growth. The second is the investments that I've talked about the investments in automation, productivity and lean are really making an impact and are very, very positive for that business, very sustainable. The third would just be the reduction of some of the issues we had last year, labor supply chain, some of those types of items. And then we did add accretive acquisitions, ASPEQ and TAMCO, which we're very pleased about. We think those have structurally brought up our segment income target is probably 100 basis points. So when we looked at it before, we thought 15% to 16% was the right target. Where we sit today, we think 18% to 20% is a very sustainable target for us going forward, the volumes that we see. So we think we've significantly and structurally improved the HVAC business, and we feel good about that. So that would be how I break [indiscernible] that down.
