Tax Deductions Every HVAC Contractor Should Know

HVAC-Specific Deductions

Refrigerant and Supplies

Every can of R-410A, every filter, every thermostat — 100% deductible. Track purchases monthly.

EPA Certification Costs

Your EPA 608 certification exam and renewal fees: deductible. NATE certification: deductible. Manufacturer training: deductible.

Vehicle and Mileage

HVAC techs drive more than most trades — service calls across town all day. At $0.70/mile, 25,000 miles = $16,750 in deductions. Use a mileage tracking app.

Tools and Diagnostic Equipment

Manifold gauges, vacuum pumps, leak detectors, multimeters — all deductible. Items over $2,500 can use Section 179 for full first-year deduction.

Seasonal Expenses

Marketing for heating season vs. cooling season counts as business advertising. Seasonal hiring costs for peak demand are deductible.
