April is bringing another round of price adjustments across the HVAC supply chain, and this month's list is worth bookmarking.

Robertshaw is up 6% effective April 6. National Comfort Products raised prices 7% as of April 16. NDL bumped copper ACR fittings 5%. Omnimax is hiking aluminum products up to 15% and copper products 12%. Solar and Palau USA is raising residential ventilation 10% and commercial 5%.

The one outlier: VTS American actually cut prices, dropping 15% on three of its modular air handling platforms effective immediately.

Tariffs on steel, aluminum, and copper are the primary driver behind most of these moves. For contractors, that means equipment pricing conversations with customers are only going to get harder as the year goes on. Locking in quotes and stocking strategically makes more sense now than waiting to see where prices land.
