Filthy, scratched out, rusted, moldy and bent out of shape HVAC coils can be a gruesome sight. In some cases, once the damage is done, some coils are just simply irreparable. This Halloween, we’re sharing photos of spooky, bizarre and downright scary scenarios where coils can be seen in some of the worst conditions ever. Continue reading to see what we mean.

Rotten to the Core

Rotted and corroded condenser coils can be a seriously costly problem. Not only can it severely reduce efficiency (to zero most likely) , but it is also a common cause of mechanical failure. Be prepared to tell your client it could require purchasing new coils, and that might cause a terrifying monster to emerge.

Fear of Filthy Coils

Yummy, fuzz. These coils are a total nightmare just waiting to happen. Expect a dramatic decrease in the energy efficiency of evaporator coils that look like these and even worse, like major system damage. Scenarios like these are due to lack of cleaning, and generally caused by customers “forgetting’ to replace filters. If left untreated, it can cause some scary issues; air flow problems, poor indoor air quality (IAQ), severe allergies, or worse, equipment failure.

Evil Evaporator Coils

If the appearance of the crumbling evaporator coils on this unit doesn’t scare you, the story on how it became this way will. A pink coil cleaner was used to clean the equipment in place and this was the end result. The cleaner was acid-based and these formulas are known to be so strong that they strip metal from coils and can severely damage sensitive aluminum fins. Don’t let this happen to you. Avoid dangerous coil cleaning scenarios like this by treating coils with alkaline-based products – not only are they are safer on coils, but they’re also less dangerous to the user and the environment.

Frightening HVAC Filters

Dirty air filters are the worst. Yuck! Buildup like hair, dander, pollutants and more, block the airflow, forcing systems to work harder and produce less efficient results. They also lead to dirty coils when the filtering just simply fails to work anymore. To make matters worse for you customer, the electric bill is sure to rise. Simply paying better attention to the air filter and when it is due for changing, could save your clients from paying hundreds of thousands of dollars in repairs. Perhaps a quarterly follow-up call to remind them might be helpful (and get you some points for being a proactive service provider).

The Pressure Washing Monster

Who did this to that poor condenser unit? The big, bad, far too powerful pressure washer. Pressure washers, or power washers, push out thousands of  PSI of cleaning power. As you can see from the image above, that amount of pressure can do a significant amount of damage to coils. New and innovative technology from SpeedClean offers better ways to clean coils, that won’t leave them looking like this. The CoilShot® Condenser, CoilJet® CJ-200 and our CoilJet® Coil Cleaner have proven to be safer and more effective alternatives that get the job done right.

Hurricane Horror

Whether it be a heavy rainstorm, hurricane, earthquake or tornado, natural disasters can do some of the most horrific damages to HVAC coils. Tall, stocky trees can tumble over and crush outdoor coils to smithereens. Floodwater can be hazardous, promotes mold growth and the longer it is left inside of the unit to penetrate the system, the greater the damage can be. When combating floodwater after a natural disaster, a wet/dry vacuum, like the BucketVac® from SpeedClean, would surely do the trick. This lightweight, portable and powerful industrial vacuum is designed to make short work of wet and dry cleaning situations.
