A central HVAC replacement is usually capitalized. A service call or component repair is current, but replacing the central system normally restores a major building system.
The expense-specific result is below. The shared BAR test, de minimis safe-harbor rule, and source guide live on the deductions hub so they are not repeated on every expense page.
A worked classification for HVAC replacement
A $420 capacitor and service call is a current line 14 repair. A $9,800 furnace and central air replacement is capitalized over 27.5 years. A separately purchased $700 window unit may be expensed under the de minimis election or treated as 5-year property.
Records that support this treatment
Keep diagnostic notes, itemized equipment and labor invoices, permits, model numbers, in-service date, and any allocation between central systems and stand-alone units.
Keep the invoice, the decision, and the Schedule E placement together. The broader rental property deductions guide and the Schedule E walkthrough cover the full return.
This is general information for organizing rental records, not tax advice. Elections, entity structure, mixed use, and the exact unit of property can change the answer. Bring the invoice and the underlying facts to a CPA before filing.
