🪣 Tony’s Full PTAC Maintenance Schedule
| Task | Frequency |
|---|---|
| Clean/replace filters | Monthly |
| Inspect condensate drain | Monthly |
| Check & clean evaporator coil | Quarterly |
| Inspect condenser coil | Quarterly |
| Check electrical connections | Annually |
| Verify refrigerant pressures | Annually |
| Clean blower wheel & fan | Annually |
🧼 Monthly: Filter Cleaning Is Your #1 Job
PTAC filters are usually reusable mesh screens.
How to clean:
1️⃣ Turn off unit.
2️⃣ Remove front panel and slide out filter.
3️⃣ Vacuum loose debris.
4️⃣ Rinse with warm water (mild detergent if needed).
5️⃣ Let air dry completely before reinstalling.
💡 Tony’s Pro Tip:
"A dirty filter reduces airflow and makes the unit work twice as hard. Clean filters save you 5-15% on energy right there."

💧 Monthly: Check Condensate Drainage
Blocked drains = puddles, mold, bad smells, and possible interior wall damage.
-
Ensure drain pans aren’t full.
-
Confirm water is draining outside.
-
Use flexible wire to gently clear minor blockages.
💡 Tony’s Take:
"Water inside means something’s clogged. If you catch it early, it’s an easy fix."
❄ Quarterly: Clean Coils Inside & Out
Evaporator Coil (inside room)
-
Use soft coil brush or fin comb.
-
Light spray with coil cleaner.
-
Vacuum debris.
Condenser Coil (outside wall)
-
Use low-pressure water spray.
-
Clean away leaves, dirt, bird nests, etc.
-
Straighten bent fins gently.

🔌 Annually: Electrical & Refrigerant Checkups
Even if your PTAC runs fine, inspect annually:
-
Tighten wire connections.
-
Look for signs of arcing or overheating.
-
Verify refrigerant levels (only certified techs can handle refrigerant work).
-
Inspect for compressor wear or early failure signs.

🔇 Annually: Blower Wheel & Fan Cleaning
-
Dust buildup throws off fan balance.
-
Causes vibrations, noise, premature motor wear.
-
Clean with a soft brush or low-pressure air.
-
Check motor bearings for wear.
💡 Tony’s Rule:
"If you hear rattling or buzzing, it’s usually a dirty or unbalanced blower."
🧪 Proactive PM vs. Emergency Repairs
| Preventive Maintenance | Emergency Repair |
|---|---|
| $100–200 per year | $400+ per service call |
| Controlled downtime | Angry tenants |
| Lower energy bills | Surprise expenses |
| Longer unit life | Shortened lifespan |
🧯 Safety Considerations
