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!

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

Dirty Coils are Costing You Money!

Prevent the Damage Before It's Too Late!

Debris clogged condenser fins and dirty coils reduce air flow, and add more heat to the system causing the compressor to work harder with higher system temperature and pressure. Dirty coils reduce the AC system cooling capacity and increase electricity consumption.

This means decreased equipment life with increased maintenance, repair and operating costs.

Preventing Equipment Damage is Easy!

This PreVent Air Filter is designed to keep any outdoor central air conditioning unit from clogging up with outdoor debris caused by Cottonwood Tree Seeds, construction dust, dryer lint, bugs, seeds, leaves or grass clippings that get sucked into your outdoor air conditioner coil.

The enclosed filter wraps around the outside of the air intake louvers or fins of your air conditioning unit. Make sure your equipment is clean first. Wrap the filter around the unit, aligning the top edge of the filter with the top of the air conditioning unit.

If the Prevent Air Filter is taller than your outdoor unit , excess filter should be folded under at the bottom.

The filter is held in place across the rear of the unit by bungee cords(enclosed). Attach one each at the top, middle, and bottom of the air filter by hooking cord ends directly through the woven filter media. If the filter is longer than the circumference of your unit, excess filter may be folded under at the edges.
