As the craze of earnings season draws to a close, here’s a look back at some of the most exciting (and some less so) results from Q1. Today, we are looking at hvac and water systems stocks, starting with CSW (NASDAQ: CSWI).

Many HVAC and water systems companies sell essential, non-discretionary infrastructure for buildings. Since the useful lives of these water heaters and vents are fairly standard, these companies have a portion of predictable replacement revenue. In the last decade, trends in energy efficiency and clean water are driving innovation that is leading to incremental demand. On the other hand, new installations for these companies are at the whim of residential and commercial construction volumes, which tend to be cyclical and can be impacted heavily by economic factors such as interest rates.

The 9 hvac and water systems stocks we track reported a satisfactory Q1. As a group, revenues beat analysts’ consensus estimates by 2.1% while next quarter’s revenue guidance was 0.7% below.

Market Update

Thanks to the Fed’s series of rate hikes in 2022 and 2023, inflation has cooled significantly from its post-pandemic highs, drawing closer to the 2% goal. This disinflation has occurred without severely impacting economic growth, suggesting the success of a soft landing. The stock market thrived in 2024, spurred by recent rate cuts (0.5% in September and 0.25% in November), and a notable surge followed Donald Trump’s presidential election win in November, propelling indices to historic highs. Nonetheless, the outlook for 2025 remains clouded by potential trade policy changes and corporate tax discussions, which could impact business confidence and growth. The path forward holds both optimism and caution as new policies take shape.
