The HVAC Problem Hiding Above Your Ceiling

A rooftop unit fails in its second summer. The compressor is dead, and the compressor is covered. The property manager files the claim expecting the manufacturer to replace the part. The claim comes back denied.

Nothing was wrong with the coverage. The problem was the paperwork. No registration on file, or no maintenance records, or the last repair used a part the manufacturer never approved. The warranty existed the whole time. It just couldn’t be proven when it mattered.

Replacing a commercial compressor or an entire RTU is a real capital hit, and this is one of the more expensive surprises in property management. It’s also almost always avoidable.

Coverage is conditional

A manufacturer warranty is not a promise to fix the equipment. It’s a limited agreement to replace specific parts under specific conditions, and it typically excludes labor. On a commercial rooftop unit, labor is often the larger cost.

Commercial terms are also shorter and more uneven than the long coverage in residential advertising. On Trane’s commercial packaged units, for example, the compressor carries roughly five years while coils and most parts carry about one. So a compressor that fails in year two is usually still covered on paper. Whether the claim actually pays depends on everything around the part: registration, documented maintenance, and who did the work.

The ways coverage quietly disappears

Denied claims commonly trace back to a handful of gaps:

• The unit was never registered, or registration lapsed. Registration is often required to activate or extend coverage, and the timeframe varies by manufacturer.
• There are no dated maintenance records from a licensed contractor. A pattern of undocumented service can give the manufacturer grounds to deny.
• A past repair used non-OEM parts or was performed by someone not authorized to work on the equipment.
• A safety control was bypassed or modified during a quick fix.
• The failure came from something warranties commonly exclude, like a power surge or flooding. In Florida, that exclusion comes up more than most owners expect.

None of these are mechanical failures. They’re record-keeping failures, and they surface at the worst possible time.

“We maintain it” is not the same as “we can prove it”

In-house teams often keep equipment running fine without keeping the kind of records a manufacturer will accept. An internal log noting that the unit was looked at won’t satisfy a claim review. Many manufacturers want dated invoices and service documentation from a licensed contractor, tied to the specific unit.

That’s the real gap. The maintenance may be happening. The proof isn’t.

Keeping coverage intact comes down to a few habits:

• Register every new unit right away, and save the confirmation.
• Keep dated service records tied to each unit’s serial number.
• Use licensed service and manufacturer-approved parts for anything under warranty.
• Hold onto invoices, even for routine work like filter changes.

The warranty isn’t the safety net. The service record is.

For a property manager, the useful question isn’t whether a failure is covered. It’s whether you can prove the unit was maintained the way the warranty required. A documented maintenance relationship does two things at once. It keeps the equipment healthier, and it builds the paper trail that makes a claim defensible.

The coverage is only worth what you can back up when the compressor quits.
