Pricing power is hiding weak HVAC demand

01 Running thesis

Price is doing the heavy lifting

Watsco is still a high-quality distributor with scale that smaller rivals cannot easily match. It buys heating, ventilation, air conditioning, and refrigeration products from many suppliers, then sells them through a large branch network to contractors and dealers. That scale gives it real pricing power.

The near-term problem is demand. In Q1 2026, same-store sales were flat. Residential ducted compressor-bearing systems fell 1% in sales because an 8% drop in units was almost fully offset by a 7% rise in average selling price. That is good pricing power, but it is not healthy volume growth.

The bull case needs a bottom in residential HVAC unit volumes, clearer EPA rules for the 410A sell-through issue, and a better housing market. If units recover while SG&A stays controlled, profits could improve quickly.

The bear case is more pressing right now. Consumers are delaying expensive replacement systems, home building is soft, and the A2L refrigerant change is still causing market friction. The open question is whether Watsco can keep raising prices if volumes keep falling.

May 2026Q1 2026 kept the bear case in focus. Same-store sales were flat only because a 7% price increase offset an 8% unit volume decline in residential ducted systems.
Feb 2026The FY2025 filing showed weaker demand for big-ticket HVAC equipment and a mix shift toward other HVAC products. The loss of federal HVAC tax credits after 2025 also weakened the high-efficiency demand story.
Nov 2025Q3 2025 made the volume problem worse, with residential ducted unit volume down 20%. Gross margin improved, but SG&A growth still hurt operating leverage.
Aug 2025Q2 2025 showed a sharp split between pricing and demand. Gross margin expanded, but residential unit volume fell 16% and SG&A rose while sales declined.
May 2025Q1 2025 improved the margin picture, with gross margin up 60 basis-points. That was offset by revenue decline and higher same-store SG&A.
Feb 2025The FY2024 filing confirmed gross margin pressure and added tariff and AI-enhanced cybersecurity risk language. The A2L refrigerant transition became a key 2025 watch item.
Nov 2024Q3 2024 showed flat same-store sales and a 50 basis-point gross margin decline. Management also pointed to marketing activity used to regain share.
Aug 2024The initial view framed Watsco as the largest HVAC/R distributor in North America. The early tension was clear: strong scale and long-term replacement demand, but near-term margin pressure.
02 Business model

Branches, brands, and contractor trust

Watsco makes money by moving HVAC/R equipment, parts, supplies, and refrigeration products from manufacturers to local contractors. The contractor needs the right system or part at the right time, often during a heat wave or cold snap. Watsco wins when its branches have inventory nearby and can serve that customer fast.

The model is seasonal. Air conditioning demand is usually strongest in the second and third quarters. Heating demand is usually strongest in the first and fourth quarters. Weather can help or hurt results in any single quarter.

Growth comes from same-store sales and acquisitions. Watsco buys smaller distributors, adds them to its network, and tries to improve purchasing, pricing, technology, and product availability. That works best when end demand is stable.

The model breaks when consumers delay replacements, suppliers raise costs faster than Watsco can pass them through, or inventory rules change faster than the channel can react. Right now, the biggest issue is not whether Watsco can sell products. It is whether customers want enough big-ticket systems.

03 Product portfolio

What Watsco sells

Cash cow

HVAC equipment

This is the main product group. It includes residential and commercial systems, furnaces, ducted and ductless systems, and indoor components.

Growth engine

Residential replacement systems

Replacement is a long-term tailwind because old systems wear out. The current issue is that consumers are delaying large purchases, shown by the 8% unit volume drop in Q1 2026.

Steady

Other HVAC products

This group includes parts and supplies that contractors need for repairs and installations. Its sales mix has been rising as equipment demand weakens.

Steady

Commercial HVAC products

Commercial HVAC is tied to business spending and construction activity. In Q1 2026, commercial HVAC equipment sales were flat.

Option

Commercial refrigeration products

This is a smaller product line, but it gives Watsco exposure beyond home heating and cooling. It can help when core residential equipment demand is soft.

Option

High-efficiency systems

Higher-efficiency systems can lift average selling prices over time. The loss of U.S. federal HVAC tax credits after December 31, 2025 removes one demand incentive.

04 Business segments

Q1 2026 sales mix

HVAC equipment65%declining

This mix is from the quarter ended March 31, 2026. Watsco reports major product lines rather than separate operating segments, and rounding means the shares may not total exactly 100%.

05 Risk factors

What could go wrong

Volume decline beats pricing power

High impact · High odds

Q1 2026 showed the core tension clearly. Residential ducted system unit volume fell 8%, while average selling price rose 7%. If unit declines continue, Watsco may not be able to hold revenue flat through price alone.

We watchQuarterly residential ducted system unit volume and average selling price.

A2L and 410A rules stay messy

Medium impact · Medium odds

The industry is shifting from older 410A systems to lower-GWP A2L systems. The EPA had not issued a final rule on the 410A installation deadline as of the Q1 2026 filing. That keeps inventory planning harder for distributors and contractors.

We watchFinal EPA rule on the 410A sell-through and installation deadline.

Gree dispute disrupts supply

Low impact · Medium odds

Gree and Watsco disagree over whether their distribution agreement renewed for another 10-year term. Gree-branded products were less than 3% of consolidated revenue for the 12 months ended March 31, 2026, so the companywide exposure is small. The risk is still real for subsidiaries that rely on those products.

We watchCourt updates, settlement news, or any interruption in Gree product purchases.

Tariffs raise product costs

Medium impact · Medium odds

Many HVAC suppliers source parts from China and Mexico or assemble products in Mexico. If tariffs or trade rules raise costs, Watsco may need to increase prices again. Higher prices could push more consumers to delay replacements.

We watchSupplier price actions tied to Mexico, China, steel, aluminum, or copper tariffs.

Weather and housing weaken together

Medium impact · Medium odds

Watsco benefits when hot summers, cold winters, and housing activity drive HVAC demand. Q1 2026 volume weakness was tied in part to lower home building activity and reduced consumer spending. Mild weather can make that worse in key selling seasons.

We watchHousing starts, housing completions, and summer or winter weather patterns in Watsco markets.
06 Quick answers

In one breath

What does Watsco do?

Watsco is a distributor of heating, ventilation, air conditioning, and refrigeration products. It sells equipment, parts, and supplies to contractors through a large branch network.

Why are Watsco volumes weak?

Management cited lingering disruption from the A2L product transition, lower home building activity, and reduced consumer spending for replacement systems and upgrades. In Q1 2026, residential ducted system unit volume fell 8%.

What is the main bull case for Watsco?

The bull case is that Watsco has scale, pricing power, and a long replacement cycle. If residential HVAC units stabilize, flat SG&A could help earnings recover faster than sales.

What is the main bear case for Watsco?

The bear case is that demand for large HVAC systems remains weak. If Watsco must rely on price increases while unit volume keeps falling, revenue and margins could come under pressure.
