HVAC Manufacturers Report Commercial Growth in Q2 2026

Two big HVAC (heating, ventilation, and air conditioning) manufacturers, Lennox and Trane Technologies, reported their second-quarter 2026 earnings, and the picture looked different depending on the market. Commercial HVAC business grew strongly for both companies, driven in large part by demand from data centers, which need heavy-duty cooling systems. Residential sales told a different story: Lennox reported a 7% drop in residential HVAC sales for the quarter, and while the residential side overall showed some improvement industry-wide, manufacturers noted that broader economic pressures are slowing further growth in that segment.

For a homeowner, this doesn't change anything about your own equipment or any rebate program you might be eligible for. It's a snapshot of how manufacturers are doing financially, split between the commercial buildings and data centers driving their growth and the slower, more cost-sensitive home market. If you're weighing a new furnace, air conditioner, or heat pump (a system that both heats and cools by moving heat rather than generating it), this kind of report mostly signals that demand from homeowners has been a bit softer lately, which is more a reflection of the economy than of any change in equipment availability or pricing you'd need to plan around.

Nothing here points to a new incentive, deadline, or product you need to act on. It's simply an update on where HVAC makers are seeing growth this year, with commercial and data-center cooling leading the way while home sales lag a little behind.
