Tax season doesn’t have to mean writing a giant check to the IRS. As an HVAC technician, you’re already juggling tools, travel, and training, so why let taxes eat into your hard-earned money?
The truth? Most HVAC pros miss out on thousands in deductions simply because they don’t know what to claim. But with the right know-how, you could slash your tax bill and keep more cash in your pocket.
This guide breaks down every deduction you qualify for, tools, mileage, uniforms,and even your work van so you can file tax with confidence
(And no, you don’t need to be a tax expert to benefit.)
Why HVAC Techs Overpay on Taxes (And How to Fix It)
Most technicians miss deductions simply because they don’t realize what counts. The IRS won’t hand you a refund for unclaimed expenses, it’s on you to track them. But with a little organization (and a few smart habits), you could slash your tax bill significantly.
For example, that
1,200 diagnostic tool you bought last year?
Deductible.
The 15,000 miles you drove for jobs?
Deductible.
Even the 500 you spent on safety boots and uniforms counts. Those overlooked expenses add up fast, potentially leaving
3,000–5,000 on the table.
The Ultimate List of HVAC Tax Deductions
1. Tools & Equipment (The Obvious—and Not-So-Obvious—Ones)
Every technician knows tools are expensive. The IRS knows it too which is why they let you write them off.
You can deduct hand tools (like gauges, wrenches, and pipe cutters), power tools (drills, vacuum pumps), and even safety gear (gloves, goggles, harnesses). Small purchases under $2,500 can often be fully deducted in one year thanks to Section 179.
Pro Tip: If you bought a 1,800 recovery machine this year, that’s 1,800 less in taxable income. At a 25% tax rate, that’s $450 back in your pocket.
Don’t forget the less obvious expenses, either. Things like software (invoicing or diagnostic apps), tool maintenance (sharpening blades, replacing parts), and storage (toolboxes, van shelving) can also be written off.
For big-ticket items (like a $5,000 vacuum pump), you might need to depreciate the cost over several years. A CPA can help navigate this.

2. Vehicle Expenses (Your Work Van Is a Tax Goldmine)
If you drive for work, you’ve got two ways to deduct vehicle costs:
The standard mileage rate lets you deduct $0.67 per mile (2025 rate) for business trips. It’s simple—just track your miles.
Alternatively, the actual expenses method allows you to deduct fuel, repairs, insurance, and even depreciation. This requires more paperwork but can save more if you drive a gas-guzzler.
Which is better? If your van is used solely for work, actual expenses usually win. For mixed-use vehicles, mileage is simpler.
To track it, use an app like MileIQ or Everlance (they auto-log trips) or keep a physical logbook as a backup.
For example, driving 15,000 work miles at 0.67 per mile equals a 10,050 deduction. At a 25% tax rate, that’s $2,512 saved.
3. Training & Certifications (Yes, You Can Write Off Learning)
Staying certified isn’t just good for business—it’s also a tax break.
You can deduct costs for EPA 608, NATE, or OSHA certification fees, HVAC training courses (online or in-person), and even study guides or exam prep materials. Travel expenses for training—like hotels, meals, and mileage—also count.
Just remember: The training must relate to your current work. Getting a plumbing cert probably won’t fly.

4. Uniforms & Work Clothing (But Not Just Any Clothes)
Not all clothing qualifies, but branded uniforms or safety gear do.
Shirts with your company logo, steel-toe boots, flame-resistant coveralls, and even dry-cleaning costs for work attire are deductible.
What doesn’t count? Plain black pants (unless they’re part of a required uniform) or everyday sneakers.
5. Home Office (If You Handle Admin Work at Home)
Even if you’re mostly in the field, you might qualify for a home office deduction if you use a dedicated space (like a desk for invoicing) and don’t have another office location.
You can claim it two ways:
- Simplified method:
- 5 per sq.ft.(max300sq.ft.
- 5 per sq.ft.(max300sq.ft.→1,500 deduction).
- Actual expenses: A percentage of rent, utilities, and internet.
Warning: Don’t get greedy, claiming 50% of your rent for a tiny desk might raise eyebrows.
6. Supplies & Materials (The Little Things Add Up)
Things like refrigerant, duct tape, wiring, office supplies (paper, ink, software subscriptions), and even marketing materials (business cards, flyers) are deductible.
Pro Tip: Snap photos of receipts with your phone and store them in Google Drive or a dedicated app.
7. Insurance & Licenses (Often Overlooked)
Don’t forget to deduct liability insurance, workers’ comp (if you have employees), state/local HVAC license fees, and even health insurance if you’re self-employed.
How to Track Expenses (Without Losing Your Mind)
You don’t need a fancy system—just consistency.
Start by separating business and personal spending (a dedicated business bank account helps). Use an app like QuickBooks Self-Employed or Wave to categorize expenses, or even a simple Excel sheet.
Always save receipts (take a photo and email it to yourself) and log mileage (apps automate this).
To audit-proof your deductions, avoid round numbers (1,200 vs 1,237 looks more legit) and keep records for at least 3 years. And if an expense feels sketchy—like deducting a family vacation—it probably is.
Real-Life Examples: How Much Could You Save?
Scenario 1: Self-Employed Tech
- $5,000 on tools
- $3,000 on training
- 10,000 miles driven ($6,700 deduction)
- $1,500 home office
Total deductions:
16,200→
16,200→4,050 saved (at 25% tax rate).
Scenario 2: W-2 Employee
- $1,000 on unreimbursed tools
- $500 on uniforms
Total deductions:
1,500→
1,500→375 saved.
(Even small deductions add up!)
Final Tips to Maximize Savings
- Consult a CPA—worth every penny if you’re self-employed.
- Don’t wait until April—track expenses monthly.
- Reinvest savings into your business (better tools, marketing, etc.).
