How much does it cost to start an HVAC company?
Starting an Air Conditioning Company costs $465,000 in modeled CAPEX, but the funding plan should cover up to $988,000 after adding the $523,000 cash trough. That ties directly to What Is The Primary Goal Of Your Air Conditioning Company?: match launch size to cash, crews, and demand.

Fixed overhead is $20,100 per month
Staff: 9 roles across sales and service
Costs depend on vehicles, techs, mix, geography
What are the biggest costs to start an HVAC company?
Starting an Air Conditioning Company is capital heavy because the work needs mobile crews, refrigerant handling gear, test tools, safety gear, and enough inventory to finish installs and emergency repairs on site. Based on the costs given, the startup stack is about $453,000, and Year 1 COGS assumptions of 180% for equipment and parts plus 60% for technician materials and supplies mean cash needs stay tight from day one.

How do you fund an HVAC business startup?
Funding an Air Conditioning Company startup is mostly about matching cash to buildout and runway, not just raising a big round. Here’s the quick math: $465,000 in CAPEX plus a $523,000 modeled cash shortfall points to a blended mix of owner investment, vehicle financing, equipment financing, a working capital loan, and supplier terms, with the model aiming at Month 30 break-even and a 57-month payback. Keep the financial model tied to loan sizing and cash-flow timing.

Key Takeaways
Vehicle CAPEX is $180,000; fuel and maintenance stay operating costs.
Tools and diagnostics need $65,000 before launch.
Inventory starts at $85,000, but COGS scales with revenue.
Licensing, insurance, and dispatch create steady monthly overhead.
Air Conditioning Company Core Five Startup Costs
Service Vehicles Startup Expense
Fleet Buildout
For launch, model $180,000 in vehicle CAPEX from Month 1 to Month 3. That budget covers purchase or lease, wraps, shelving, ladder racks, refrigerant storage, GPS, fuel setup, tools loaded per van, and the first commercial auto insurance impact. Size it to crew count, because Year 1 field coverage is tied to 2 lead HVAC technicians and 3 HVAC technicians.
Cost Split
Estimate this cost as units × buildout cost × months of coverage. Keep the vehicle CAPEX in startup assets, and keep fuel, maintenance, and insurance in operating expenses. That split makes the launch cash need clear and stops fleet spending from hiding the true install margin.
Quote one buildout per van
Match vans to technician coverage
Track insurance by vehicle count
Lean Fleet
Keep fleet fuel and maintenance at 45% of revenue as an operating check, not CAPEX. Match vans to booked jobs and the 5-person Year 1 field team instead of buying ahead of demand. Commercial auto insurance should also scale with crew count and technician coverage.
Buy only for staffed routes
Separate CAPEX from monthly spend
Review insurance after hiring
Budget View
Show two lines in the budget: $180,000 upfront for vehicle buildout, then monthly fuel, maintenance, and insurance below the line. That way you can test whether a team of 2 lead HVAC technicians and 3 HVAC technicians can stay covered without squeezing service margins.
Shop Office Dispatch And Launch Readiness Startup Expense
Shop Setup Cost
The launch build is mostly CAPEX: $45,000 for office setup and furniture, $35,000 for warehouse equipment, $25,000 for computer equipment, $18,000 for software licenses and setup, and $12,000 for marketing materials and signage. That is $135,000 before monthly run costs start.
Monthly Readiness
Recurring operating readiness totals $14,800 per month: office and warehouse rent $8,500, software subscriptions $1,800, utilities and communications $1,200, professional services $2,500, and office supplies and equipment $800. Add the $48,000 Year 1 marketing budget separately, since that is not a one-time setup cost.
$8,500 rent each month
$1,800 software each month
$48,000 marketing in Year 1
Dispatch Build
Dispatch setup should fund scheduling, service routing, accounting, branded materials, recruiting, and training. Here’s the quick math: if the office runs 2 lead HVAC technicians plus 3 HVAC technicians, the system has to support crew planning and field coordination from day one, not just desks and phones.
Cost Control
Keep CAPEX and recurring spend separate so the launch budget stays clean. Buy only what supports day-one dispatch, then stage upgrades after routing, accounting, and training are stable. The monthly mix matters because rent, software, utilities, and services create the cash burn long before field revenue scales.
HVAC Tools And Diagnostic Equipment Startup Expense
Tool Package
Budget $65,000 across Month 1 to Month 5: $28,000 for specialized HVAC tools, $22,000 for diagnostic equipment, and $15,000 for safety gear. This covers gauges, vacuum pumps, recovery machines, leak detectors, meters, hand tools, ladders, power tools, PPE, and calibration so the team can launch with install and repair capability.
Budget Inputs
Estimate this line from vendor quotes, technician count, and months of coverage. Price the core tool set in Month 1 to 3, then add diagnostic gear in Month 3 to 5. Keep safety equipment as separate CAPEX. Do not fold in technician materials and supplies; those run at 60% of Year 1 revenue.
Buy Discipline
Control spend by standardizing the buy list, getting at least two quotes, and avoiding duplicate meters or specialty gear before demand proves it. Calibrate only what you will use, and track replacement dates. The goal is launch-ready service, installation, and repair work, not a fully loaded shop on day one.
Cash Split
Keep tool CAPEX separate from technician materials and supplies, which run at 60% of Year 1 revenue. That split keeps cash planning honest: equipment buys are one-time, while job consumables scale with revenue. If the team cannot install, service, and repair on day one, the tool package is too thin.
Licensing Bonding And Insurance Startup Expense
Compliance setup
This budget covers state contractor licensing, local registrations, EPA Section 608 refrigerant certification, and any bond your state or city requires. Use $600 for licenses and permits, plus $1,500 per month for training and certifications during launch. State rules vary, so this is a compliance budget, not legal advice.
Monthly insurance
Model $3,200 per month for insurance across general liability, commercial auto, workers’ compensation, and umbrella coverage. If the carrier asks for an upfront deposit, record that separately. The monthly premium stays an operating expense. One line: more trucks and more techs usually means higher insurance.
Rate drivers
Price the policy by vehicle count, headcount, and payroll mix. A larger field team needs more auto and workers’ comp exposure, especially when vans carry tools and refrigerant. Keep certificates current, match coverage to actual trucks, and avoid paying for a fleet size you do not yet run.
Count vans before quoting
Use payroll for workers’ comp
Separate any policy deposits
Launch cash need
For launch planning, the compliance stack starts at $5,300 before any upfront deposits: $3,200 in monthly insurance, $600 in permits, and $1,500 in training and certifications. That keeps cash planning honest while the field team and vehicle count are still being built.
Initial Parts And Inventory Startup Expense
Initial Stock Build
Plan $85,000 of inventory from Month 2 to Month 4 to cover filters, thermostats, capacitors, contactors, refrigerant, copper lines, drain supplies, sheet metal basics, installation materials, and vendor account setup. Keep stocked repair parts separate from HVAC units sold per job or financed through suppliers. That split protects cash when install volume lags.
What To Budget
Use the Year 1 mix to size buys: system installation at 450%, emergency repairs at 350%, maintenance contracts at 250%, and system monitoring at 150%. Here’s the quick math: if parts and equipment COGS run at 180% of Year 1 revenue, inventory planning has to support both jobs and service calls without tying up too much cash.
Quote vendor lead times first
Separate job stock from unit stock
Track usage by service type
Keep Cash Moving
Reduce upfront strain by stocking fast-moving repair parts only, then ordering customer-sold units per job or financing them through suppliers. That keeps the shelf full for emergency repairs and maintenance while limiting dead stock. One clean rule helps: buy for turns, not for pride.
Set min-max reorder points
Watch obsolete parts monthly
Match buys to booked work
Stock Mix Discipline
Vendor setup matters because it shortens lead times on high-use items like refrigerant, contactors, and copper line sets. If on-hand stock misses one peak repair week, the cash hit is more than the part cost. Build the first order around repair velocity and install coverage, not a full warehouse fantasy.
