PROTECT YOUR AIR CONDITIONER AGAINST COTTONWOOD

Cottonwood Air Filter Screens

ARE COTTONWOOD SEED CLOGGING YOUR AIR CONDITIONER?

ARE COTTONWOOD SEEDS CLOGGING YOUR AIR CONDITIONING CHILLERS?

Cottonwood Season - Cottonwood seeds clogging air conditioners in Texas usually lasts about 4 weeks in the Spring around May.

Cleaning the backside of air conditioning condenser coils has always been a time-consuming challenge and requiring several man hours in labor costs.

And time is money!

Now there is a quick and effective means of applying an external air filter media preventing most of debris from ever reaching the coils and reducing the total man hours to just minutes.

Designing AC Condenser Coils for the Real World

Has The NEWS ever considered doing a story on why condenser coils get dirty quickly? I’ve been in the HVACR business for over 40 years now and never understood why manufacturers of condenser coils for commercial a/c units can never build a coil that is made for planet Earth and not for outer space.

Condenser coil fin spacing should be made just like they did on the older refrigeration units — anywhere between 8-12 fins per inch.

Any more than this and servicemen have to lug either the power washer on roofs or lift the heavy, bulky tanks of CO2 just to clean these coils, only to hope that they will stay clean for the rest of the summer, with dirt and cottonwood only making things worse.

When manufacturers are asked, they always say “They’re cheaper to make them this way,” never considering the serviceman out in the real world.

I hope this will get the attention of engineers to start making their coils higher, wider, or thicker and consider the serviceman out there, instead of only the engineering side.

To say it simply, “If you can’t see through the coils when they are clean, they shouldn’t be built”!

Why Buy a PreVent Outdoor Air Conditioner Filter!

The outdoor air conditioner coil is exposed to unfiltered outdoor air and dirt.

A dirty air conditioner coil reduces the Air Conditioning System's ability to cool.

According to EPA research, 0.042 inch of dirt on an air conditioning coil can reduce its cooling efficiency by 21%.

A cleaner Air Conditioner Coil gives you better cooling, better air flow, better heat transfer, lower compressor temperature and pressures, and lower electric bill.

This PreVent Air Filter is designed to keep any outdoor air conditioner coil from clogging up with outdoor debris caused by construction dust, dryer lint, bugs, seeds, leaves and grass clippings.

Leaves inside the grille blocking air flow!

Title: Cottonwood seed clogging air conditioner in Austin TX

QUESTION:
My husband and I recently moved into a rental house that has a very tall cottonwood tree in the backyard. It has been shedding its seeds all over our yard since the beginning of May and seems to still be going full speed. It looks like snow, but snow that clogs up our A/C unit. I would like to know how much longer it will probably be seeding (we are in south Austin, 78744) and if you have any suggestions for our landlord as to how we can save our A/C unit from being constantly clogged.

Use the Permatron Prevent Air filter for the air conditioner!

ANSWER:
Populus deltoides (eastern cottonwood) is native to Travis County and its seeds have long been the bane of anyone living around it. In particular, those flying puffs of cotton are extremely allergenic. The cottonwood itself is not very popular, as it tends to drop big limbs, has large roots, and weak wood. It grows very fast, particularly in a moist area, and you can still see them coming up in creek beds in Texas. We found a website from Hortiscope Questions on Cottonwood that has all kinds of good information, including the name of a product thought to inhibit the cotton production. We were never able to find any information on how much longer the cottonwoods will be flying cotton in the Austin area, but the above-mentioned website said that it usually lasts about 4 weeks. Depending on where the tree is growing, of course, that will be earlier or later in the Spring than now.
