How to:

increase your ptac unit's lifespan


Cleaning and maintaining your PTAC unit could be the difference between an early and costly replacement or not. When it comes to PTAC units, they need to be maintained annually to maintain efficiency and increase their lifespan. You wouldn’t drive your car without oil or gas, right? PTAC units are just like cars — if they aren’t maintained they simply won’t start! Generally, our PTAC units have a lifespan of around 10 years if maintained properly. 

Learn how to increase the lifespan of your PTAC unit in 5-easy-to-follow steps below!

PTAC Unit Longevity

What effects the lifespan of a PTAC unit?

Unit Usage

If your units are running 24/7, chances are they're going to wear out faster!


Units located in lower level suites will accumulate more dirt, dust, and debris than units located on higher levels.


PTAC units that are maintained annually last-longer!

Learn-to: Increase The Lifespan Of Your PTAC

In 5 easy-to-follow steps


Clean & Replace Filters


Clean Room-Side Front Cover


Check PTAC Blower Wheel


Tidy Indoor & Outdoor Coils


Complete Seasonal Check-Ups

1. Clean & replace filters

Keeping PTAC unit filters clean is crucial to preserving the health of your units. Much like oil in a car, filters need to be changed every 3-6 months to prevent the unit from dying.

2. Clean room-side front cover

Remove and clean a unit’s front cover monthly to maintain unit longevity. Use a vacuum and mild cleaning agent to remove debris, but make sure everything is dry before powering the unit back on!

3. Check PTAC blower wheel

Ensure the unit’s blower wheel is free of debris! By maintaining a clean blower fan you can decrease the amount of energy your PTAC is using to stay powered. Try sliding a piece of cardboard in between the blower fan and unit opening to prevent debris build up.

4. Tidy indoor & outdoor coils

Much like your unit’s filters, coils must also be well maintained to increase the longevity of your unit. Coils should be replaced or cleaned every 1-2 years!

5. Complete seasonal check-ups

Staying on top of your seasonal check-ups is crucial to maintaining your unit’s health. The closer your PTAC unit is installed to the ground level, the more dust, dirt, and debris it will accumulate. Make sure to inspect ground and lower level units annually for maintenance.

The Benefits

Why regular unit maintenance is crucial


Units that are well maintained produce less noise. Dirt, dust, and debris build-up cause the PTAC unit's fans to work much harder. This extra-work produces more noise-disturbance and causes the fans to wear out faster.

More Efficient

PTAC units run more efficiently when parts are cleaned and replaced regularly. You can reduce your overall energy consumption and save money on your energy bill.

Longer Lasting

Double the lifespan of your unit by completing annual check-ups. On average, our PTAC units last 8-12 years when they're well maintained.


Long story short — show your PTAC units some love (regularly). 

Taking care of your PTAC unit means more than just a longer lifespan – it saves you money and keeps things quieter too! By sticking to simple maintenance steps like cleaning filters, checking the blower wheel, and giving it seasonal checkups, you’re ensuring it runs smoothly for longer.

With factors like usage habits, weather, and regular TLC, you’ll keep your PTAC unit(s) running efficiently and quietly. So, don’t forget to give your PTAC some love – it’ll thank you with years of reliable service and lower energy bills!
