HVAC installation and service businesses carry a heavy equipment load relative to revenue, and the deduction strategy should front-load depreciation through Section 179 and bonus depreciation. The typical HVAC business has three revenue streams (new installations, service/repair, and maintenance contracts), each with different expense profiles and seasonal patterns.

✓Key takeaway

Major HVAC installer deductions:

Specialty equipment:

Recovery machines (refrigerant recovery): $1,000-$5,000
Manifold gauge sets, digital pressure gauges: $200-$800
Vacuum pumps: $300-$1,500
Refrigerant scales: $200-$500
Leak detectors (electronic): $200-$600
Combustion analyzers: $500-$2,000
Duct leakage testers (blower door): $2,000-$5,000
Sheet metal tools (brakes, shears, crimpers): $500-$3,000
Brazing and soldering equipment: $200-$500
All items under $2,500: deductible in full under the de minimis safe harbor
Items over $2,500: Section 179 or 5-year MACRS depreciation

Work vehicles:

Service vans (Ford Transit, Chevy Express, Ram ProMaster): $35,000-$55,000
Most HVAC service vans exceed 6,000 lbs GVWR: full Section 179 deduction
Van upfitting (shelving, ladder racks, generator mount): deductible as part of the vehicle or separately as equipment
Fleet vehicles: track mileage per vehicle if any personal use occurs
Fuel, maintenance, insurance: deductible (actual method or standard mileage for personally-owned vehicles)

Refrigerant and consumables:

R-410A, R-22 (for service on older systems), R-32, R-454B
Refrigerant prices are volatile and can be a significant cost ($50-$300 per unit depending on type)
Copper tubing, line sets, fittings: cost of goods sold
Solder, brazing rods, flux: supplies
Duct materials (flex duct, rigid duct, duct board): COGS
Filters, belts, capacitors, contactors (service parts): COGS or supplies

Licensing and certification:

EPA Section 608 certification: required to purchase and handle refrigerant
State and local contractor licenses: deductible
NATE certification: deductible
Manufacturer training (Carrier, Trane, Lennox, etc.): deductible, including travel to training centers
Continuing education: deductible

Insurance:

General liability: $2,000-$5,000/year
Workers’ comp (if employees): 5-12% of payroll
Commercial auto: per vehicle
Tools and equipment floater: deductible
Professional liability (errors and omissions): deductible

Technology and software:

ServiceTitan, Housecall Pro, or similar field service software: $100-$500/month
GPS fleet tracking: $20-$40/vehicle/month
Estimating and design software (Manual J, D, S calculations): deductible
Tablets/phones for technicians: deductible

Maintenance contracts (revenue and expense):

Maintenance agreements generate recurring revenue (often at lower margins)
The labor cost of performing maintenance visits is deductible
Parts used during maintenance (filters, capacitors): deductible
Maintenance revenue smooths seasonal cash flow

What does the first-year tax picture look like for HVAC?

Hypothetical example

Round numbers. An HVAC S-Corp in its second year (past startup, established customer base). Revenue: $350,000. Owner salary: $70,000. Two service technicians.

Revenue breakdown:

New installations: $200,000 (57%)
Service/repair: $100,000 (29%)
Maintenance contracts: $50,000 (14%)

Cost of goods sold:

Equipment (furnaces, condensers, air handlers): $100,000
Refrigerant and materials: $15,000
Duct materials: $10,000
Service parts: $8,000
Total COGS: $133,000

Gross profit: $217,000

Operating expenses:

Technician wages: $100,000 ($50,000 each)
Owner salary + employer FICA: $70,000 + $5,355 = $75,355
Workers’ comp (8% x $170,000 payroll): $13,600
General liability insurance: $3,500
Commercial auto (3 vehicles): $6,000
Fuel and vehicle maintenance: $12,000
New service van purchase (Section 179): $42,000 (GVWR over 6,000 lbs)
Equipment purchases (Section 179): $8,000 (recovery machine, gauges, vacuum pump)
ServiceTitan subscription: $4,800
GPS tracking (3 vehicles): $1,200
Marketing (Google Ads, HomeAdvisor): $6,000
Office rent/shop: $9,600
Phone, internet, supplies: $4,000
Licensing and training: $2,000
Total operating expenses: $188,055

Taxable income (K-1 to owner): $28,945

Without the Section 179 deductions ($50,000 on the van + equipment), the K-1 would have been $78,945. The first-year deduction on the service van alone saves approximately $10,000 in combined income tax and reduced self-employment tax equivalent.

Owner’s total tax:

W-2 income tax + FICA on $70,000 salary: approximately $21,000
K-1 income tax (after QBI): approximately $4,500
Total: approximately $25,500 on $350,000 revenue (7.3% of gross)

Year 2+ (no large Section 179 purchases):

K-1 increases to approximately $78,945
Tax on K-1 increases by approximately $10,000
Total tax: approximately $35,500

This is why HVAC businesses should plan vehicle and equipment purchases strategically. Buying a van every 3-4 years and timing major equipment purchases to offset high-income years smooths the tax liability.
