Appliance repair has a distinctive deduction profile because parts are a significant expense (15-30% of revenue) that fluctuates with the type of repairs performed. A $20 thermostat replacement generates mostly labor profit, while a $400 compressor replacement has a much thinner margin. The parts cost creates a natural variability in net profit that other labor-only trades don’t experience. Beyond parts, the major deductions are vehicle expenses (appliance techs drive 15,000-25,000 business miles/year going house to house), tools and diagnostic equipment, insurance, and manufacturer training. The EPA Section 608 certification (required for any work involving refrigerants) and manufacturer-specific training are fully deductible professional development expenses.

✓Key takeaway

Appliance repair deduction categories:

Parts (15-30% of revenue, the largest variable cost):

Control boards: $100-$400 each (most expensive common part)
Compressors: $200-$600 each
Motors (washer, dryer, dishwasher): $80-$250 each
Thermostats, switches, relays: $10-$50 each
Belts, hoses, seals: $5-$30 each
Water inlet valves: $20-$60 each
Heating elements: $30-$100 each
Wholesale markup: techs buy at 40-60% of retail, sell at retail or slight markup
Deducted as cost of goods sold (if maintaining inventory) or supplies expense
Unsold parts inventory at year-end: not deductible until sold or used

Parts inventory management (tax implications):

If carrying significant inventory ($3,000+): should report as COGS with beginning/ending inventory
If ordering parts per-job (just-in-time): can deduct as supplies when purchased
Many solo techs use the just-in-time model (order from supply house, pick up same day)
Common parts inventory (carried on the truck): $1,000-$3,000

Tools and diagnostic equipment:

Multimeter: $50-$200 (replace every 2-3 years)
Clamp meter: $50-$200
Refrigerant manifold gauges: $100-$300
Refrigerant recovery machine: $500-$1,500
Leak detector: $100-$400
Thermometer (IR and probe): $50-$200
Hand tools (nut drivers, socket sets, pliers, screwdrivers): $500-$1,000
Appliance dolly/hand truck: $100-$300
Drain snake (for dishwasher/washer work): $50-$200
Replacement per year: $500-$1,500
All under $2,500: de minimis safe harbor (expense immediately)

Vehicle expenses (significant for mobile service):

Business miles: 15,000-25,000/year
Standard mileage (2025): 70 cents/mile
At 20,000 miles: $14,000 deduction
Home office establishes the home as principal place of business
Every trip from home to a customer’s home is a business mile
Without home office: first and last trip of the day are non-deductible commuting

Insurance:

General liability: $500-$1,500/year
Commercial auto: $1,500-$3,000/year
Errors and omissions (if doing warranty work): $500-$1,500/year
Tools/equipment floater: $200-$500/year
Total: $2,700-$6,500/year

Certifications and training:

EPA Section 608 (Type I, II, III, or Universal): $150-$300 (test fee)
Manufacturer training (Samsung, LG, Whirlpool, GE, etc.): $200-$1,000 per brand
ISCET (International Society of Certified Electronics Technicians): $200-$400
Continuing education: $200-$500/year
All fully deductible under IRC 162

Technology:

Scheduling/dispatch software (Housecall Pro, ServiceTitan): $50-$200/month
Parts lookup database subscription: $20-$50/month
Accounting software: $20-$50/month
Cell phone (business use): $50-$100/month

What does the full deduction picture look like?

Hypothetical example

Round numbers. A solo tech, EPA 608 Universal certified, authorized for 3 manufacturer brands. Single filer. 4-5 calls/day, 5 days/week, 50 weeks.

Revenue: $150,000 (1,000 calls, average ticket $150 including parts)

Parts cost breakdown:

Part Category	Annual Cost	% of Revenue
Control boards and electronics	$8,000	5.3%
Motors and compressors	$6,000	4.0%
Small parts (thermostats, switches, seals)	$5,000	3.3%
Hoses, belts, consumables	$3,000	2.0%
Specialty parts (ice makers, dispensers)	$4,000	2.7%
Refrigerant	$2,000	1.3%
Shipping/handling on ordered parts	$2,000	1.3%
Total parts	$30,000	20.0%

Other deductions:

Category	Amount
Vehicle mileage (18,000 x $0.70)	$12,600
Insurance (GL + auto + E&O)	$4,000
Phone + scheduling software	$2,400
Tools (replacement/upgrade)	$1,200
Marketing (Google, Yelp, Thumbtack)	$2,400
Certifications and training	$600
Home office (actual method)	$2,500
Accounting/bookkeeping	$1,200
Total non-parts	$26,900

Total deductions: $30,000 + $26,900 = $56,900 Net profit: $150,000 - $56,900 = $93,100

Parts cost as a deduction lever: The tech’s parts cost ($30,000) is larger than their vehicle deduction ($12,600). This is unusual in the trades. For context:

A handyman’s materials: $3,000-$5,000 (2-3% of revenue)
A power washer’s chemicals: $3,000-$8,000 (3-8%)
An appliance tech’s parts: $30,000 (20%)
A painting contractor’s paint: $30,000-$50,000 (20-35%)

The “diagnostic only” call optimization: Some calls result in a diagnostic fee only ($80-$150) with no repair (customer declines, or the appliance isn’t worth repairing). These calls are nearly pure profit:

Revenue: $120
Parts cost: $0
Time: 30-45 minutes (vs. 1-2 hours for a full repair)
Effective hourly rate: $160-$240/hour

If 20% of calls are diagnostic-only: 200 calls x $120 = $24,000 in revenue with $0 parts cost. This pulls the effective parts percentage down and pushes margin up.

Manufacturer authorization investment: Becoming an authorized service provider for major brands:

Training cost: $500-$1,000 per brand
Benefits: higher call volume (manufacturer referrals), warranty parts at no cost, credibility
Revenue impact: 200+ additional calls/year
The training is fully deductible, and the revenue increase (200 x $100 warranty calls = $20,000) produces 10x+ ROI on the training cost
