Free checklist

Packaged terminal air conditioner (PTAC) annual maintenance checklist

The annual PTAC 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 HVAC service tech on the annual, with the room out of service long enough to slide the chassis from the sleeve.

When in the schedule

Once a year in a shoulder season, deep enough to reach the fouling on the blower wheel and the back of the coils that the front-grille filter change never touches.

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.

01

Chassis and deep cleaning

  • Chassis pulled and both coils deep-cleaned

    Chassis slid from the sleeve, indoor and outdoor coils cleaned through the full fin depth, dirt packed between the sections removed, bent fins combed and drainage confirmed after rinse.

  • Blower wheel, pan and slinger cleaned

    Blower wheel cleaned of film to restore airflow, base pan scrubbed to bare surface, slinger ring cleaned and free to throw condensate, drain path proven clear.

02

Sleeve and seal

  • Wall sleeve and gasket inspected and re-sealed

    Sleeve checked for corrosion and pitch to the exterior, gasket and any weather seal renewed at the chassis-to-sleeve joint, exterior grille secure with no gaps for wind-driven rain.

03

Electrical, controls and operation

  • Electrical connections and compressor draw checked

    Terminal and disconnect connections tight with no heat discoloration, compressor and fan amp draw read against the data plate, capacitor sound where fitted.

  • Full heat and cool operation and controls verified

    Unit run through heat and cool with the chassis reseated, discharge temperatures reasonable, thermostat or panel calibrated, setback and setpoint limits reset as intended.

What usually sends this back

The failures are almost always the evidence, not the work

  • Coils rinsed only from the front while the packed dirt between the indoor and outdoor coil sections stays, so capacity never comes back and the compressor runs hot.
  • Blower wheel left caked with the film the filter let past, quietly costing half the airflow that a clean filter is credited with restoring.
  • Chassis reinstalled without re-seating the sleeve gasket, so the room takes on outside air and the unit short-cycles chasing a load that leaks straight back in.

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.

Common questions

What does this packaged terminal air conditioner (ptac) annual checklist cover?
5 items across 3 sections, covering chassis and deep cleaning, sleeve and seal, electrical, controls and operation. 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 HVAC service tech on the annual, with the room out of service long enough to slide the chassis from the sleeve.
When in the schedule should this walk happen?
Once a year in a shoulder season, deep enough to reach the fouling on the blower wheel and the back of the coils that the front-grille filter change never touches.
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 packaged terminal air conditioner (ptac) annual inspection?
Coils rinsed only from the front while the packed dirt between the indoor and outdoor coil sections stays, so capacity never comes back and the compressor runs hot. Blower wheel left caked with the film the filter let past, quietly costing half the airflow that a clean filter is credited with restoring. Chassis reinstalled without re-seating the sleeve gasket, so the room takes on outside air and the unit short-cycles chasing a load that leaks straight back in.
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.
