Direct Answer

> TL;DR: Commercial HVAC distribution is a relationship-and-line-card business where outside reps manage 250–600 contractor accounts each, ship equipment and aftermarket parts on a 35–55 day net cycle, and live or die by seasonal pull-through (May–August cooling, November–February heating). The nine KPIs that run the branch are line-card wallet share, equipment-to-aftermarket mix, contractor account active rate, gross margin by SKU class, GMROI, same-day fill rate, dead-stock ratio, manufacturer program enrollment, and quote-to-PO conversion. Operators like Watsco, Carrier Enterprise, Johnstone Supply, Lennox PartsPlus, and F.W. Webb run weekly KPI scorecards on Salesforce, NetSuite, or Epicor Eclipse and review GMROI quarterly with manufacturer reps. Typical targets: equipment gross margin 14–19%, parts margin 28–38%, blended GMROI 2.4–3.2, and 92%+ same-day fill on A-class SKUs.

The 2027 commercial HVAC distributor lives between three pressures: refrigerant phase-down (R-410A to A2L transition), labor-strapped contractor customers who want counter-pickup and same-day delivery, and OEM dealer agreements that demand quarterly purchase commitments. KPIs have to track all three or the branch quietly bleeds margin. The rest of this entry walks through how the work actually flows, the nine measures that run the place, the operators who do it well, the failure modes that recur, the cadence you should hold, a 30/60/90 plan for a new branch manager or sales director, an FAQ for the questions that show up in every QBR, and the sources behind the numbers.

Why Commercial HVAC Distribution Sells Differently

Four mechanics shape every KPI in this category, and they are not optional context — they are the reason your dashboard looks different from electrical or plumbing distribution.

1. The line card is the moat. A branch carrying Carrier, Mitsubishi, or Daikin equipment has a structurally different customer base than a parts-only Johnstone or independent multi-line house. Carrier Enterprise locations sell almost exclusively to Carrier-credentialed contractors. Lennox PartsPlus stores serve Lennox dealers first. Independent multi-line houses (F.W. Webb, Geary Pacific, Heritage) compete on breadth, counter speed, and credit. KPIs like wallet share and program enrollment only make sense when scored against the line card you actually carry.

2. Equipment and aftermarket behave like two businesses. A 7.5-ton rooftop unit moves at 12–17% gross margin with a 4–8 week lead time and ties up significant working capital per unit. A box of TXVs moves at 32–40% margin, ships same-day from the counter, and turns 6–9 times a year. A healthy branch hits roughly 55–65% revenue from equipment and 35–45% from parts/controls/refrigerants — but parts deliver the majority of gross profit dollars. Reps who chase equipment volume without aftermarket attach destroy GMROI quietly.

3. Seasonality compresses the calendar. May–August accounts for the bulk of annual cooling-side revenue in most U.S. markets; November–February drives heating-side revenue. Branches that don't pre-build inventory in March and September run out of A2L mini-splits and condensing furnaces at peak — fill rate craters, contractors switch suppliers, and wallet share leaks for several quarters. Reporting cadence has to anticipate the curve, not chase it.

4. The contractor buyer is time-poor and credit-sensitive. Mechanical contractor owners run small truck fleets, dispatch from a phone, and place the majority of orders through counter pickup, text-to-order, or the e-commerce portal — not through a formal RFQ. The outside rep's job is consultative: refrigerant transition planning, controls retrofits, manufacturer rebate stacking, and credit-line management. Selling like a commodity distributor (price-down, push-product) fails quickly because the contractor will move SKU classes to whoever shows up with a Daikin VRV design assist.

The 9 KPIs, In Depth

These nine run a commercial HVAC distribution branch in 2027. Numbers are blended across U.S. independent and OEM-aligned distributors and reflect HARDI distributor benchmark data, Watsco public disclosures, and operator interviews. Treat the ranges as planning targets, not guarantees — local market share and line-card strength move every number.

1. Line-Card Wallet Share by Active Contractor. The dollar share of a contractor's annual HVAC purchases captured by your branch, derived from contractor self-reported volume or manufacturer co-op reporting. Target: 45–60% with A-tier accounts (top 20 contractors), 25–35% with B-tier, 12–20% with C-tier. Below 30% on an A-tier account means a competitor is winning a SKU class you should own.

2. Equipment-to-Aftermarket Revenue Mix. Equipment (rooftops, splits, chillers, furnaces, air handlers) as a percentage of total branch revenue, with aftermarket (parts, controls, refrigerants, accessories) as the balance. Target: 55–65% equipment / 35–45% aftermarket. When equipment exceeds 70% the branch is under-attaching; when aftermarket exceeds 50% the line card is leaking equipment sales to a competing distributor.

3. Active Contractor Account Rate. Percentage of named accounts that placed at least one order in the trailing 90 days. Counter-pickup, e-commerce, and rep-placed orders all count. Target: 78–88% for A/B accounts, 55–70% for C accounts. A double-digit drop quarter-over-quarter is an early signal of competitor encroachment or a credit-policy problem.

4. Gross Margin by SKU Class. Tracked separately for equipment (target 14–19%), parts (28–38%), controls (24–32%), refrigerants (8–14% on raw R-32/R-454B, 18–26% on cylinders with takeback), and accessories (32–42%). Blended branch GM target: 22–27%. Anything below 21% means equipment mix is too rich or rep discounting is unmanaged.

5. GMROI (Gross Margin Return on Inventory Investment). Annual gross profit dollars divided by average inventory at cost — the single most important profitability KPI for a multi-line branch. Target: 2.4–3.2 blended; 1.8–2.4 on equipment-heavy lines; 3.5–5.0 on parts and controls. Watsco-owned branches publicly target north of 3.0; HARDI medians sit in the mid-2s.

6. Same-Day Fill Rate on A-Class SKUs. Percentage of order lines for the top 400–600 SKUs filled from on-hand stock without backorder. Counter pickup and will-call are weighted in. Target: 92–96% for A-class, 84–90% for B-class, 70–80% for C-class. Below 90% on A-class and contractors begin routing emergency calls to a competitor even if your line card is preferred.

7. Dead and Slow Stock Ratio. Inventory at cost with zero movement in 180 days, as a share of total inventory. Target: under 6% for parts, under 10% for equipment, under 4% for refrigerants. Through the A2L transition many branches are carrying elevated dead stock on R-410A equipment — a forced writedown event that should be modeled into 2027 budgets, not absorbed quietly.

8. Manufacturer Program Enrollment Rate. Percentage of active dealer-program contractors enrolled in the OEM rebate/co-op program you administer (Carrier Factory Authorized, Trane Comfort Specialist, Lennox Premier, Daikin Comfort Pro). Target: 70–85% of A/B accounts enrolled, with strong rebate-claim attach. Drives meaningful margin enhancement and locks in line-card preference.

9. Quote-to-PO Conversion Rate and Cycle Time. Percentage of formal quotes (typically project equipment over $8K) that convert to purchase order, with median cycle time. Target: 38–52% conversion at a 12–22 day median cycle. Sub-30% conversion means quotes are being used as price-checks against a primary distributor and the rep needs to qualify deeper before quoting.

Real Operators

Five operators that run these KPIs visibly and well.

Watsco (Carrier Enterprise, Gemaire, Baker Distributing). The largest HVAC distributor in North America, with several hundred locations. Public filings disclose inventory turns, GMROI, and e-commerce penetration (well over a third of orders in recent years). Operates the OnCallAir mobile platform for contractor quoting and integrates with the HVACpartners portal for Carrier-aligned dealers. Branch managers run weekly scorecards on the nine KPIs above using a proprietary BI stack on top of their distribution ERP and CRM.

Carrier Enterprise (Watsco JV with Carrier Global). A brand-focused channel for Carrier, Bryant, Payne, and Heil equipment across many U.S. locations. Runs deep Carrier Factory Authorized Dealer program enrollment, with mature markets showing high A-tier enrollment. Equipment-to-aftermarket mix typically skews toward equipment, with parts coming through the parallel Totaline branded line.

Johnstone Supply. A member-owned cooperative network of several hundred independently owned wholesale locations, primarily aftermarket parts, controls, and refrigerants. Counter-driven, multi-line, competing on breadth and counter speed. Strong same-day fill metrics — leading stores hit the mid-90s on A-class SKUs. Uses Epicor Eclipse-class ERP and the Johnstone proprietary catalog system across the network.

Lennox PartsPlus. Lennox International's owned distribution channel of roughly 250 stores. Primarily serves Lennox Premier Dealers with equipment, Lennox-branded and generic parts, and controls. Tight integration with Lennox factory rebate and co-op programs pushes program enrollment high among active dealers.

F.W. Webb. A Northeast independent distributor with dozens of branches spanning plumbing, HVAC, and industrial PVF. Multi-line and family-owned, known for credit flexibility and design-assist on commercial mini-split and VRF projects. Quote-to-PO conversion tends to run at the upper end of the benchmark on engineered projects because of the design-assist motion.

Additional operators worth naming for reference: Daikin Comfort Technologies Distribution (Goodman/Amana/Daikin channel), Heritage Distribution Holdings (independent multi-line), Geary Pacific Supply (West Coast independent), Mingledorff's (Southeast Carrier distributor), Russell Sigler (Carrier West), and R.E. Michel (Mid-Atlantic multi-line).

Failure Modes

Four failure modes that recur in branch-level postmortems.

1. Equipment volume chased without aftermarket attach. A rep books a large rooftop equipment package at a thin margin and skips the duct accessories, controls retrofit, refrigerant kit, and startup tools. The contractor sources those from a counter-house competitor and the branch never wins them back on that account. Equipment-to-aftermarket mix drifts toward 72/28, blended GM falls toward 19%, GMROI drops below 2.2, and the branch underperforms plan despite a "strong" top line. Fix: every equipment quote must carry a parallel attach quote with 8–14 line items, and the rep's variable comp pays on attach gross profit, not equipment revenue.

2. A2L and refrigerant transition mismanaged. R-410A equipment built before the A2L transition is stranded inventory if it sits past the 2027 cooling season. Branches that didn't run an aggressive sell-through campaign carry elevated dead stock by mid-2027. Fix: monthly aged-inventory review with a forced markdown ladder (e.g., 5% at 120 days, 12% at 180, 25% at 270, writedown at 360) and a co-op-funded contractor incentive program negotiated with the OEM rep.

3. Credit and AR drift during peak season. Contractor AR balances expand sharply from April to August as cooling-season equipment ships. Branches that don't tighten credit holds in March end up with material 90-day past-due balances by September, forcing reactive collections during the slowest selling weeks of the year. Fix: pre-season credit review every February and August, with rep-level visibility into account AR aging and order-hold authority.

4. Counter and e-commerce treated as overflow, not as the primary channel. Contractor buyers want counter pickup or text-to-order for most transactions. Branches that under-staff the counter or run a stale e-commerce catalog lose share on B and C accounts first, then A accounts within 12–18 months. Fix: counter is a first-class P&L line with its own staffing model, training budget, and KPI scorecard; e-commerce SKU coverage and order accuracy track on the weekly review.

Reporting Cadence

Cadence is what separates a branch that compounds from one that surprises itself in Q3.

Daily.

Fill rate on A-class SKUs (previous-day order lines, by branch)
Counter and e-commerce order count vs same-day-prior-year
Will-call backlog and unshipped-equipment count
Refrigerant cylinder stock and incoming-truck ETAs
AR holds released and credit exceptions approved

Weekly.

Branch revenue and gross profit by SKU class vs plan
Equipment-to-aftermarket mix
Active contractor account count (rolling 90-day)
Top 25 accounts: order frequency and wallet share movement
Quote pipeline and aging (anything over 30 days flagged)
Rep scorecards: revenue, GP, attach rate, new account activations

Monthly.

Full P&L with GMROI by SKU class and by line
Dead and slow stock ratio with forced-action list
Manufacturer program enrollment and rebate-claim status
Customer AR aging with named-account remediation plan
Seasonal pre-build progress against forecast (March and September especially)

Quarterly.

QBR with each OEM (Carrier, Trane, Daikin, Mitsubishi, Lennox) on co-op spend, program enrollment, line growth, and forecast commitments
A-tier contractor QBRs: wallet share trend, project pipeline, refrigerant transition planning
Inventory health review with finance: writedown reserve, dead stock action, working capital
Rep variable-comp recalibration against attach and GMROI performance
Annual budget refresh in Q4 with weather, refrigerant cycle, and labor-market assumptions

30/60/90 Day Plan

For a new branch manager, sales director, or VP of sales joining a commercial HVAC distributor.

Days 0–30: Diagnose.

Pull two years of branch P&L by SKU class, GMROI by line, and dead-stock aging
Ride along with three outside reps and spend two full days behind the counter
Sit through one full QBR with each top-three OEM rep on your line card
Interview the top 15 contractor accounts (in person if possible) on what they buy elsewhere and why
Audit the CRM (Salesforce, NetSuite CRM, or Epicor CRM): quote pipeline accuracy, account ownership, attach-rate visibility
Establish the baseline numbers for all nine KPIs and lock the weekly scorecard format

Days 31–60: Stabilize.

Tighten credit holds and run a pre-season AR review with finance
Launch monthly aged-inventory action: forced markdowns and OEM co-op buy-back conversations on R-410A and obsolete SKUs
Rebuild the rep variable-comp plan to pay on GP attach and GMROI, not equipment revenue alone
Re-enroll A and B contractor accounts in OEM dealer programs they're not currently signed into
Audit counter staffing and e-commerce SKU coverage; fix the top 10 broken portal SKUs
Run a one-day all-rep training on refrigerant transition (A2L safety, cylinder handling, contractor talk track)

Days 61–90: Build.

Lock the 2027 pre-build plan for cooling season (March) and heating season (September) by SKU
Negotiate Q3 and Q4 co-op spend with each OEM tied to specific contractor enrollment and project pipeline targets
Stand up the design-assist workflow with manufacturer reps on Daikin VRV, Mitsubishi VRF, and chiller projects
Launch the first quarterly A-tier contractor QBR cycle with wallet share and refrigerant transition as standing agenda items
Publish the 2027 branch operating plan with monthly P&L, GMROI, and KPI targets for finance and ownership review

FAQ

Q1: How do you calculate wallet share when contractors don't disclose total spend? A: Three methods, used in combination. First, manufacturer co-op reporting — Carrier, Trane, Daikin, and Lennox share dealer purchase data with their authorized distributors as part of the dealer agreement. Second, contractor QBR self-reporting — A-tier accounts typically share annual purchasing budgets in exchange for program benefits and pricing tiers. Third, modeled estimation from truck count, service area, and project mix using HARDI contractor benchmarks. Triangulating all three usually lands within roughly 8–12 points of actual.

Q2: What's the right balance between OEM-aligned and multi-line strategy? A: It depends on the line card and the market. OEM-aligned channels (Carrier Enterprise, Lennox PartsPlus, Daikin direct) capture more of the dealer-program economics — enrollment, co-op, brand loyalty — but cap addressable contractor base at the OEM-credentialed dealer count. Multi-line independents (F.W. Webb, Heritage, Geary Pacific) reach a broader contractor base with parts and competing equipment lines but typically run lower equipment GM. Most healthy branches sit somewhere on the spectrum based on local market share and line-card strength.

Q3: How should we think about refrigerant transition risk in 2027? A: A2L refrigerants (R-32 and R-454B) are the new baseline for residential and light commercial split equipment under the EPA's AIM Act phase-down. Inventory of R-410A pre-build equipment is the highest-risk SKU class for writedown through 2027. Three actions matter: aggressive sell-through with contractor incentives co-funded by the OEM, monthly aged-inventory review with forced markdown ladders, and reserve provisioning in the branch P&L so the writedown doesn't surprise ownership in Q4. On the parts side, R-410A service refrigerant remains saleable but margin compresses as production phases down.

Q4: How do you compensate outside reps to drive attach and GMROI rather than revenue? A: Variable comp pays on gross profit dollars, not revenue, with an attach multiplier on aftermarket GP and a GMROI gate that suspends bonus payment on accounts running below 2.0 GMROI for two consecutive quarters. New-account activation pays a one-time bonus on the first three orders. Equipment-only deals without attach pay at a reduced rate. Reps adjust behavior within about 90 days when the comp plan is published clearly and the scorecard is visible weekly.

Q5: What tools matter for running these KPIs in 2027? A: ERP — Epicor Eclipse, NetSuite, Infor SX.e, or SAP for parts-and-equipment distribution. CRM — Salesforce remains the dominant choice (often with a distribution accelerator); NetSuite CRM and Epicor CRM are used inside their ERP installs. E-commerce and quoting — Watsco's HVACpartners and OnCallAir are reference standards for Carrier-aligned channels, with Unilog and similar platforms for independents. BI — Tableau, Power BI, or Phocas (widely used in HARDI distribution) layered on the ERP. Manufacturer portals — HVACpartners (Carrier), Trane Connect, Daikin City, and Mitsubishi Diamond Designer for design and rebate workflows.

Q6: How quickly should a new branch see KPI improvement? A: Fill rate, dead-stock action, and credit-hold discipline move within 30–60 days. Attach rate and equipment-to-aftermarket mix shift over 90–120 days as rep comp and quoting workflow change. Wallet share is slower — roughly 9–15 months — because contractor purchasing habits anchor to relationships and credit lines. A GMROI improvement of 0.3–0.6 points is realistic inside 12 months on a previously under-managed branch, with another 0.3–0.5 in year two as inventory mix and program enrollment tighten.

**Carrier Enterprise (Watsco JV with Carrier Global).** A brand-focused channel for Carrier, Bryant, Payne, and Heil equipment across many U.S. locations. Runs deep Carrier Factory Authorized Dealer program enrollment, with mature markets showing high A-tier enrollment. Equipment-to-aftermarket mix typically skews toward equipment, with parts coming through the parallel Totaline branded line.

**Johnstone Supply.** A member-owned cooperative network of several hundred independently owned wholesale locations, primarily aftermarket parts, controls, and refrigerants. Counter-driven, multi-line, competing on breadth and counter speed. Strong same-day fill metrics — leading stores hit the mid-90s on A-class SKUs. Uses Epicor Eclipse-class ERP and the Johnstone proprietary catalog system across the network.

**Lennox PartsPlus.** Lennox International's owned distribution channel of roughly 250 stores. Primarily serves Lennox Premier Dealers with equipment, Lennox-branded and generic parts, and controls. Tight integration with Lennox factory rebate and co-op programs pushes program enrollment high among active dealers.

**F.W. Webb.** A Northeast independent distributor with dozens of branches spanning plumbing, HVAC, and industrial PVF. Multi-line and family-owned, known for credit flexibility and design-assist on commercial mini-split and VRF projects. Quote-to-PO conversion tends to run at the upper end of the benchmark on engineered projects because of the design-assist motion.

Additional operators worth naming for reference: **Daikin Comfort Technologies Distribution** (Goodman/Amana/Daikin channel), **Heritage Distribution Holdings** (independent multi-line), **Geary Pacific Supply** (West Coast independent), **Mingledorff's** (Southeast Carrier distributor), **Russell Sigler** (Carrier West), and **R.E. Michel** (Mid-Atlantic multi-line).

## Failure Modes

Four failure modes that recur in branch-level postmortems.

**1. Equipment volume chased without aftermarket attach.** A rep books a large rooftop equipment package at a thin margin and skips the duct accessories, controls retrofit, refrigerant kit, and startup tools. The contractor sources those from a counter-house competitor and the branch never wins them back on that account. Equipment-to-aftermarket mix drifts toward 72/28, blended GM falls toward 19%, GMROI drops below 2.2, and the branch underperforms plan despite a "strong" top line. Fix: every equipment quote must carry a parallel attach quote with 8–14 line items, and the rep's variable comp pays on attach gross profit, not equipment revenue.

**2. A2L and refrigerant transition mismanaged.** R-410A equipment built before the A2L transition is stranded inventory if it sits past the 2027 cooling season. Branches that didn't run an aggressive sell-through campaign carry elevated dead stock by mid-2027. Fix: monthly aged-inventory review with a forced markdown ladder (e.g., 5% at 120 days, 12% at 180, 25% at 270, writedown at 360) and a co-op-funded contractor incentive program negotiated with the OEM rep.

**3. Credit and AR drift during peak season.** Contractor AR balances expand sharply from April to August as cooling-season equipment ships. Branches that don't tighten credit holds in March end up with material 90-day past-due balances by September, forcing reactive collections during the slowest selling weeks of the year. Fix: pre-season credit review every February and August, with rep-level visibility into account AR aging and order-hold authority.

**4. Counter and e-commerce treated as overflow, not as the primary channel.** Contractor buyers want counter pickup or text-to-order for most transactions. Branches that under-staff the counter or run a stale e-commerce catalog lose share on B and C accounts first, then A accounts within 12–18 months. Fix: counter is a first-class P&L line with its own staffing model, training budget, and KPI scorecard; e-commerce SKU coverage and order accuracy track on the weekly review.

## Reporting Cadence

Cadence is what separates a branch that compounds from one that surprises itself in Q3.

**Daily.**
- Fill rate on A-class SKUs (previous-day order lines, by branch)
- Counter and e-commerce order count vs same-day-prior-year
- Will-call backlog and unshipped-equipment count
- Refrigerant cylinder stock and incoming-truck ETAs
- AR holds released and credit exceptions approved

**Weekly.**
- Branch revenue and gross profit by SKU class vs plan
- Equipment-to-aftermarket mix
- Active contractor account count (rolling 90-day)
- Top 25 accounts: order frequency and wallet share movement
- Quote pipeline and aging (anything over 30 days flagged)
- Rep scorecards: revenue, GP, attach rate, new account activations

**Monthly.**
- Full P&L with GMROI by SKU class and by line
- Dead and slow stock ratio with forced-action list
- Manufacturer program enrollment and rebate-claim status
- Customer AR aging with named-account remediation plan
- Seasonal pre-build progress against forecast (March and September especially)

**Quarterly.**
- QBR with each OEM (Carrier, Trane, Daikin, Mitsubishi, Lennox) on co-op spend, program enrollment, line growth, and forecast commitments
- A-tier contractor QBRs: wallet share trend, project pipeline, refrigerant transition planning
- Inventory health review with finance: writedown reserve, dead stock action, working capital
- Rep variable-comp recalibration against attach and GMROI performance
- Annual budget refresh in Q4 with weather, refrigerant cycle, and labor-market assumptions

## 30/60/90 Day Plan

For a new branch manager, sales director, or VP of sales joining a commercial HVAC distributor.

**Days 0–30: Diagnose.**
- Pull two years of branch P&L by SKU class, GMROI by line, and dead-stock aging
- Ride along with three outside reps and spend two full days behind the counter
- Sit through one full QBR with each top-three OEM rep on your line card
- Interview the top 15 contractor accounts (in person if possible) on what they buy elsewhere and why
- Audit the CRM (Salesforce, NetSuite CRM, or Epicor CRM): quote pipeline accuracy, account ownership, attach-rate visibility
- Establish the baseline numbers for all nine KPIs and lock the weekly scorecard format

**Days 31–60: Stabilize.**
- Tighten credit holds and run a pre-season AR review with finance
- Launch monthly aged-inventory action: forced markdowns and OEM co-op buy-back conversations on R-410A and obsolete SKUs
- Rebuild the rep variable-comp plan to pay on GP attach and GMROI, not equipment revenue alone
- Re-enroll A and B contractor accounts in OEM dealer programs they're not currently signed into
- Audit counter staffing and e-commerce SKU coverage; fix the top 10 broken portal SKUs
- Run a one-day all-rep training on refrigerant transition (A2L safety, cylinder handling, contractor talk track)

**Days 61–90: Build.**
- Lock the 2027 pre-build plan for cooling season (March) and heating season (September) by SKU
- Negotiate Q3 and Q4 co-op spend with each OEM tied to specific contractor enrollment and project pipeline targets
- Stand up the design-assist workflow with manufacturer reps on Daikin VRV, Mitsubishi VRF, and chiller projects
- Launch the first quarterly A-tier contractor QBR cycle with wallet share and refrigerant transition as standing agenda items
- Publish the 2027 branch operating plan with monthly P&L, GMROI, and KPI targets for finance and ownership review

## FAQ

**Q1: How do you calculate wallet share when contractors don't disclose total spend?**
A: Three methods, used in combination. First, manufacturer co-op reporting — Carrier, Trane, Daikin, and Lennox share dealer purchase data with their authorized distributors as part of the dealer agreement. Second, contractor QBR self-reporting — A-tier accounts typically share annual purchasing budgets in exchange for program benefits and pricing tiers. Third, modeled estimation from truck count, service area, and project mix using HARDI contractor benchmarks. Triangulating all three usually lands within roughly 8–12 points of actual.

**Q2: What's the right balance between OEM-aligned and multi-line strategy?**
A: It depends on the line card and the market. OEM-aligned channels (Carrier Enterprise, Lennox PartsPlus, Daikin direct) capture more of the dealer-program economics — enrollment, co-op, brand loyalty — but cap addressable contractor base at the OEM-credentialed dealer count. Multi-line independents (F.W. Webb, Heritage, Geary Pacific) reach a broader contractor base with parts and competing equipment lines but typically run lower equipment GM. Most healthy branches sit somewhere on the spectrum based on local market share and line-card strength.

**Q3: How should we think about refrigerant transition risk in 2027?**
A: A2L refrigerants (R-32 and R-454B) are the new baseline for residential and light commercial split equipment under the EPA's AIM Act phase-down. Inventory of R-410A pre-build equipment is the highest-risk SKU class for writedown through 2027. Three actions matter: aggressive sell-through with contractor incentives co-funded by the OEM, monthly aged-inventory review with forced markdown ladders, and reserve provisioning in the branch P&L so the writedown doesn't surprise ownership in Q4. On the parts side, R-410A service refrigerant remains saleable but margin compresses as production phases down.

**Q4: How do you compensate outside reps to drive attach and GMROI rather than revenue?**
A: Variable comp pays on gross profit dollars, not revenue, with an attach multiplier on aftermarket GP and a GMROI gate that suspends bonus payment on accounts running below 2.0 GMROI for two consecutive quarters. New-account activation pays a one-time bonus on the first three orders. Equipment-only deals without attach pay at a reduced rate. Reps adjust behavior within about 90 days when the comp plan is published clearly and the scorecard is visible weekly.

**Q5: What tools matter for running these KPIs in 2027?**
A: ERP — Epicor Eclipse, NetSuite, Infor SX.e, or SAP for parts-and-equipment distribution. CRM — Salesforce remains the dominant choice (often with a distribution accelerator); NetSuite CRM and Epicor CRM are used inside their ERP installs. E-commerce and quoting — Watsco's HVACpartners and OnCallAir are reference standards for Carrier-aligned channels, with Unilog and similar platforms for independents. BI — Tableau, Power BI, or Phocas (widely used in HARDI distribution) layered on the ERP. Manufacturer portals — HVACpartners (Carrier), Trane Connect, Daikin City, and Mitsubishi Diamond Designer for design and rebate workflows.

**Q6: How quickly should a new branch see KPI improvement?**
A: Fill rate, dead-stock action, and credit-hold discipline move within 30–60 days. Attach rate and equipment-to-aftermarket mix shift over 90–120 days as rep comp and quoting workflow change. Wallet share is slower — roughly 9–15 months — because contractor purchasing habits anchor to relationships and credit lines. A GMROI improvement of 0.3–0.6 points is realistic inside 12 months on a previously under-managed branch, with another 0.3–0.5 in year two as inventory mix and program enrollment tighten.
