Running Cost 1 : Direct Labor/Wages

Largest Fixed Cost

Your largest fixed cost in 2026 is personnel payroll, totaling $11,667 per month. This covers the Owner Operator salary of $75,000 and the Lead HVAC Technician salary of $65,000 annually. Managing this expense defintely dictates your break-even timeline.

Payroll Inputs

This monthly fixed labor cost requires setting salaries for key roles upfront. You need the annual salary for the Owner Operator ($75k) and the Lead HVAC Technician ($65k). Divide the total annual compensation by 12 months to get the monthly burn rate. This is your baseline overhead before taxes and benefits.

Owner Operator: $75,000/year
Lead Technician: $65,000/year
Monthly Total: $11,667

Labor Use

Since this is fixed labor, optimization means maximizing technician utilization. The goal is to ensure the Lead Technician is billable for most hours, not just training or setup. Avoid hiring until revenue reliably covers the $65,000 salary plus associated employer burden costs.

Maximize billable hours immediately.
Keep owner draw low initially.
Use subcontractors for spikes only.

Labor vs. COGS

Payroll is your biggest fixed anchor at $11,667/month. Contrast this with your variable Cost of Goods Sold (COGS), which starts at 120% of revenue in 2026. You need high average revenue per job just to cover the cost of parts before paying the technician wages.

Running Cost 2 : Inventory and Installation Parts (COGS)

Parts Cost Structure

Inventory and installation parts are a direct Cost of Goods Sold (COGS) for your service. This cost starts high, hitting 120% of total revenue in 2026. You must drive efficiency here quickly, as this percentage is currently higher than your sales income.

Calculating Parts Cost

This COGS line covers the actual hardware-the smart thermostat units, wiring, mounting brackets, and consumables used per job. To estimate accurately, you need the bill of materials for your standard install package, multiplied by projected job volume. For 2026, this cost is 1.2 times what you bring in from sales. What this estimate hides is the initial capital needed to stock inventory before the first sale.

Parts cost per thermostat install.
Supplier volume discounts.
Initial stock levels required.

Reducing Parts Drag

Getting this cost down is critical; the projection shows it falling to 100% by 2030 through scale efficiencies. Focus on negotiating better pricing as volume increases. Standardizing installation procedures reduces waste and over-ordering of miscellaneous components. You defintely need tighter inventory tracking to avoid obsolescence.

Standardize install kits.
Negotiate supplier tiers.
Track inventory turns closely.

COGS Efficiency Target

Managing parts procurement is not just about saving money; it directly impacts your gross margin profile until you hit the 100% COGS target. Every dollar saved here flows straight to the bottom line, improving working capital management sooner.

Running Cost 3 : Specialist Subcontracted Labor (COGS)

High Subcontractor Dependency

You are heavily reliant on outside specialists right now. In 2026, 80% of your revenue goes straight to subcontractors as a cost of goods sold (COGS). This variable cost structure demands immediate action to hire and train your own people fast.

Subcontractor Cost Basis

This line item covers the specialized labor you pay third parties to complete installations when your internal team is booked or lacks specific skills. It scales directly with sales volume. To calculate this cost, you need the total monthly revenue multiplied by 80%, based on 2026 projections.

Input: Total Monthly Revenue.
Input: Subcontractor Invoice Rate.
Fit: Major pressure point until internal techs start.

Shifting the Labor Mix

Reducing this high variable cost means replacing subcontractor invoices with your fixed payroll expenses, like the Lead HVAC Technician salary. Every job you bring in-house improves contribution margin, even if fixed costs rise slightly. You need to start hiring now, defintely.

Prioritize hiring internal headcount now.
Use subs only for peak overflow volume.
Negotiate better rates with key subs.

The Margin Lever

Your path to profitability hinges on managing the transition from 80% reliance on subcontractors to a model driven by your $11,667/month internal payroll. This shift directly improves gross margins significantly.

Running Cost 4 : Online Marketing Budget

Initial Marketing Spend

Your 2026 online marketing budget starts at $15,000 annually, but hitting a $120 Customer Acquisition Cost (CAC) is the real metric defining your growth potential. If you can't achieve that CAC, scaling revenue becomes expensive fast, eating into margins quickly.

Budget Inputs

This initial $15,000 covers ads driving leads for your thermostat installation service. To hit the $120 CAC, you need to know how many leads actually become paying customers. If your average service revenue is $400, a $120 acquisition cost means you need 3.3x payback just on marketing.

Annual spend target: $15,000 (2026)
Target cost per customer: $120
Focus on lead quality now

Managing CAC

You must manage this spend by improving conversion rates from initial lead to booked job. If you spend $120 but only 30% of leads book, your true cost per installation is $400. Focus your spend on zip codes matching your ideal homeowner profile to cut wasted impressions.

Improve lead-to-sale conversion
Test ad copy rigorously
Track cost by specific channel

Scaling Check

Hitting that $120 CAC is defintely non-negotiable for scaling revenue in 2026. If initial testing shows CAC is $200, you need to immediately pause spend and rework your offer or target audience; don't just throw more money at a broken funnel.

Running Cost 5 : Vehicle Fuel and Maintenance

Vehicle Cost Reality

Vehicle costs are a major variable expense for this installation business. Expect fuel and service van maintenance to consume 50% of total revenue in 2026. This high percentage directly ties operational capacity to sales volume. You need tight route planning to keep this ratio manageable. Honestly, that's a big chunk of your gross margin.

Tracking Van Expenses

This 50% estimate covers all travel between customer sites and routine service for the van. To validate this, you need actual fuel receipts and maintenance quotes tied to daily routes. If revenue projections shift, this cost moves proportionally. It's a direct cost of service delivery, so track it closely.

Input: Fuel consumption per route mile.
Input: Scheduled preventative maintenance costs.
Budget Fit: Variable cost, scales with jobs completed.

Cutting Mobility Costs

Since this is 50% of revenue, small reductions give big returns. Focus on route density first; fewer miles between jobs means less fuel burn. Avoid unnecessary trips by ensuring the technician has all parts before leaving the base. You might defintely save 5% to 10% by optimizing routes.

Prioritize jobs in tight geographic clusters.
Negotiate fleet pricing on fuel cards.
Schedule maintenance proactively, not reactively.

Operational Risk Check

If your average job distance is longer than planned, this 50% figure will balloon quickly. High fuel prices or unexpected major van repairs in 2026 could push this ratio above 55%, crushing your gross margin before overhead even hits. That's a serious operational risk to monitor weekly.

Running Cost 6 : Storage and Software Overhead

Fixed Overhead Base

Fixed overhead covering storage and software is $2,450 monthly across six categories. This baseline must be covered by gross profit before the business generates net income, making volume defintely crucial.

Storage and Software Breakdown

Storage and software overhead is a critical fixed expense that anchors your operations. The $1,200 monthly storage rent covers physical space for parts inventory, while $250 covers essential CRM/Scheduling software. These two items alone account for $1,450 of your total $2,450 fixed overhead base.

Storage rent: $1,200/month.
Software subscription: $250/month.
Total overhead base: $2,450/month.

Managing Fixed Infrastructure

Managing fixed overhead means ensuring utilization is high enough to absorb these costs quickly. Since storage rent is fixed, look for shared warehouse space or negotiate lease terms if you aren't using the full capacity. Software costs are easier targets for reduction if you find a less expensive CRM that still meets scheduling needs.

Review storage lease terms now.
Audit software usage monthly.
Consolidate tools to cut redundancy.

Impact on Break-Even

Because storage and software are fixed, they pressure your contribution margin until you hit volume milestones. If your average contribution margin per job is $150, you need about 16 jobs just to cover this $2,450 overhead before paying wages or marketing. This fixed cost floor needs constant attention.

Running Cost 7 : Business Liability Insurance

Mandatory Fixed Risk Cost

Business Liability Insurance costs a fixed $350 monthly, which you must budget for. This coverage is non-negotiable because your service involves both HVAC system interaction and low-voltage electrical setup, exposing you to significant operational risk.

Cost Inputs and Coverage

This insurance protects the business from claims related to property damage or bodily injury during installations. You need the $350 monthly quote locked in before day one of operations. As a fixed cost, it hits your budget regardless of installation volume, unlike variable COGS components like parts or subcontractor fees.

Covers property damage claims.
Mandatory for electrical work.
Fixed monthly expense.

Managing Premium Spend

You can't reduce this cost much without sacrificing necessary protection, but shop quotes annually. Avoid bundling unrelated coverages that inflate premiums unnecessarily. A common mistake is assuming the general contractor policy covers specialist installation errors; it usually doesn't.

Shop quotes every 12 months.
Increase deductible carefully.
Ensure coverage matches scope.

Risk Reality Check

If onboarding takes 14+ days, churn risk rises, but failing to secure this coverage means a single accident could bankrupt the entire operation instatly. Don't skimp here; it's foundational protection for high-risk trade work.
