Cottonwood Trees

[Fulltimer50]

Just a reminder for those who might be near cottonwood trees. Look at your rooftop A/Cs. The Cotton clogs up the A/C condenser. I have done this before but I am always looking for a better way. First I used a handheld Dyson. No Joy, got clogged in no time. So I pulled off most of the cotton by hand as it came off in sheets. Then used the water hose being careful not to splash the inards any more than necessary .

Buy some screen material and line the cover openings.

Good idea!

Screening would still have to be cleaned.

Are you referring the the vertical opening at the rear of the cover?

I would not add screen to those openings. Typical window screens cut airflow 50% or more when airflow is above static pressure e.g. the fan pulling air over the coils.

Yup! Just the the screen inside the outlet vent of a dryer.

Why would I want to have a screen on the dryer outlet? :coolsmiley:

If you did: I suspect that it would an epic struggle! :coolsmiley:

Use something like chicken wire. About 1/4 hole squares. It won't stop air flow but it will stop the big chunks of cottonwood, leaves, etc. Cut a strip bend it a little in a radius and hot glue it in place.
I did this on our last SOB with Dometic Aircell AC's and it worked great.
