Air-cooled condensing unit annual maintenance checklist
The annual condensing unit service is the deep pass: the measurements, cleanings and tests a quarterly round doesn't reach. This checklist keeps the full service on record with the photos that make it defensible later. Work is commonly verified against manufacturer's published instructions. Confirm the edition your authority having jurisdiction has adopted.

Who runs it
The licensed refrigeration tech on the annual, the only one touching the refrigerant circuit.
When in the schedule
Once a year at cooling-season startup, so the coil clean, the charge check and the electrical service all happen before the unit is leaned on.
The checklist
Every item, and the photo that proves it
The photo count on each row is what RTI would require before the item can be submitted. Copy the list as is, or load it into RTI and let the gate enforce it.
Coil and airflow
- 2 photos
Condenser coil deep-cleaned through the rows
Coil cleaned through the full depth with the correct cleaner and pressure, debris flushed from between the rows, fins combed straight afterward.
Refrigerant side
- 2 photos
Refrigerant charge verified by measurement
Charge confirmed by subcooling or superheat per the unit's method rather than a gauge glance, readings compared against the manufacturer's target for the conditions.
- 1 photo
Refrigerant circuit leak-checked
Connections, service ports and coil checked for oil staining or leaks, any suspected leak confirmed with a detector, no signs of past top-offs masking a leak.
Electrical and compressor
- 2 photos
Contactors, relays and wiring serviced
Contactor points inspected for pitting and burning, connections tightened, no discolored or brittle wiring, capacitors within tolerance where fitted.
- 1 photo
Compressor and motor readings within nameplate
Compressor and fan-motor amp draw read against nameplate, crankcase heater working where fitted, no unusual start behavior or noise.
What usually sends this back
The failures are almost always the evidence, not the work
- Charge judged by a single gauge glance instead of a proper subcooling or superheat reading, so a slow leak or an overcharge rides for another season.
- Contactor points burned and pitted left in service, so the compressor eventually fails to pull in on a hot-day start and the call comes in as a no-cool.
- Coil pressure-washed hard enough to lay the fins flat, trading a dirty coil for an airflow-starved one.
Run it with the Photo Gate
A checklist nobody can submit half-finished
Load this list into RTI, stick a QR tag on the area it covers, and the submit button stays locked until every mandatory item is answered and the 8 required photos exist. Approved walks roll into a branded turnover package with a tamper-evident record behind every line.
Submission state
The gate is enforced on the server, so it holds even if the phone is offline when the walk happens.
Common questions
- What does this air-cooled condensing unit annual checklist cover?
- 5 items across 3 sections, covering coil and airflow, refrigerant side, electrical and compressor. Each item spells out what the person walking the job is actually looking for, not just a box to tick.
- Who should run this inspection?
- The licensed refrigeration tech on the annual, the only one touching the refrigerant circuit.
- When in the schedule should this walk happen?
- Once a year at cooling-season startup, so the coil clean, the charge check and the electrical service all happen before the unit is leaned on.
- Why does every item ask for a photo?
- 8 of the 5 items call for photo evidence. A checklist answer without the photo is a claim; the photo is what makes the record worth something in a dispute and lets a reviewer approve work without re-walking the job.
- What most often fails a air-cooled condensing unit annual inspection?
- Charge judged by a single gauge glance instead of a proper subcooling or superheat reading, so a slow leak or an overcharge rides for another season. Contactor points burned and pitted left in service, so the compressor eventually fails to pull in on a hot-day start and the call comes in as a no-cool. Coil pressure-washed hard enough to lay the fins flat, trading a dirty coil for an airflow-starved one.
- Can I use this checklist in RTI?
- Yes. Start a free RTI workspace, build this list as a checklist, and the Photo Gate holds the submit button until every mandatory item is answered and its photos are attached. Approved inspections roll into a branded turnover package with a tamper-evident audit trail.
