Multiple HVACR manufacturers have announced price increases ranging from 3% to 15% where amounts are disclosed. Most of the increases take effect at the beginning of November 2026.
Why it matters
The announced increases raise costs for contractors and suppliers in the heating, ventilation, air conditioning and refrigeration sector, which may be passed along to buyers. The staggered effective dates indicate that pricing pressure will extend through the end of November 2026.
Manufacturer-announced increases range from 3% to 15% where amounts are disclosed, including 8% at Southwark and 6% at Artis Metals. The amounts for Parker Hannifin HVAC Filtration and Airzone have not been disclosed.

Timeline
November 1, 2026: Duro Dyne, Mars Air Systems, Southwark, Zebra Instruments and Resideo/Honeywell increases take effect.
November 2, 2026: Artis Metals, Modular Metal Fabricators and IBC Tankless Heaters increases take effect.
November 16, 2026: Parker Hannifin HVAC Filtration increase takes effect.
November 23, 2026: Airzone and Gastite increases take effect.
Industry Pattern
The staggered November 2026 announcements from multiple HVACR suppliers, spanning ducts, controls, metals and filtration, show cost increases moving through several tiers of the same supply chain at once. Because the effective dates run from November 1 to November 23, contractors face a rolling sequence of price changes rather than a single adjustment.
Homeowners and contractors buying HVAC equipment, ducts and filtration parts in November 2026 may face higher costs, with increases ranging from 3% to 15% depending on the manufacturer and product. Buyers planning replacements or installations may find it useful to compare pricing before the staggered effective dates.
The takeaway
Staggered supplier price increases mean HVAC costs may keep rising through late November 2026. Buyers planning equipment purchases or repairs may benefit from acting before the earliest effective dates.
What happens next
Additional price increases take effect on November 16, 2026 for Parker Hannifin HVAC Filtration and on November 23, 2026 for Airzone and Gastite.
