Clean Coils Lead to Healthy HVAC Compressor.

Keeping the condenser coil and evaporator coil clean is one way to maintain a healthy HVAC compressor. As the blog linked to in this post states, “Dirty coils are a surefire way to damage a compressor and negatively impact compressor efficiency.”

Product Unleashed: Coil Cleaner as Low $3.47 a Gallon

After doing some research, I found that coil cleaners are ranging from $10 all the way to $40 for a gallon of cleaner.

Did you know that CRT has a coil cleaner? Did you also know that our Powder Keg – coil cleaner is as low as $3.47 a gallon.

Our Powder Keg coil cleaner is in the form of a powder for convenience purposes. It is easy to handle, cheap to ship, and very easy to clean up. All you or the contractors have to do is mix with water at the job site, spray Powder Keg on the coil, and then rinse off. It’s as easy as that.

Why do you & your clients want Instant Powder Keg?

Powder Form – Mix With Water On Site
• Easy Clean Up If Spilled
• Easier To Haul, Ship, or Store
• Proportion Control
• Low Price per Gallon
• Results Are Impeccable



*Tip of the day: You always want to rinse any coil cleaner off of the coil because if left on, it will start to eat away the fins of the coil (as they are aluminum).

I can’t wait to see how Powder Keg can transform your spring HVAC Cleaning as well as be less costly for you. Give me a call for more info. I can’t wait to hear from you.

From the Field: You’ll Re-Coil Just at the Thought of This!

Whether you are changing filters, refurbishing or fixing HVAC systems, testing the chemicals in the water or testing for the micro-organisms in the air, there is one thing you know for certain: Nobody really wants the dirty job of cleaning dirty coils in often tight and contaminated spaces.

Dirty coils cost the owners money in system inefficiency and maintenance labor. And these problems can be minor when compared to the potential liabilities of a building airstream contaminated with all that has accumulated on the coils. Yes, that same airstream that just keeps circulating round and round the building, passing through those dirty coils each time.

Depending on the type of environment, coil cleaning may need to be done every three months or even more frequently (such as in a fast food restaurant where grease is sucked into the air handlers).

This certainly keeps the internal maintenance staff employed, and fills the pockets of contractors who make their money for each visit. But where the company needs to economize on internal labor costs, or where a contractor is on a service contract and gets paid for result rather than the number of visits – there is a far superior solution.

First Strike Micro Coat is a revolutionary product which coats the coils with a transparent, molecular barrier that prevents dirt (and all the rest of those undesirable particles) from sticking. Instead, they just wash into the condensate pan along with the condensation.

This product is so amazing that one hospital was able to reduce their coil cleanings from once every three months to just once every three years!

Technical Corner: Tips for Cleaning Dirty Air Conditioner Coils

It is difficult to clean HVAC coils effectively due in part to coil design.  For multiple row coils, the copper tubing is staggered, and this prevents a stream of water from entering into the coils too deeply.  Usually the water velocity penetrates only the first few inches of a coil to loosen deposits.

Fouled coils lead to increased pressure drop across the coils. When pressure drop increases, more fan horsepower is required. This in turn draws more power, resulting in greater current consumption.

Pressure drop measurements across the coil when it is new are a valuable base line for performance.  Differential pressure that increases by more than one and a half to two times for sure indicates problems with coil cleanliness.

Cleaning coils also plays an important part in air quality.

Here are some rules to follow in cleaning coils:

1)Hot water always works better than cold water when it comes to cleaning.

2)Foaming cleaners, such as our product Instant Powder Keg, are generally better than non-foaming cleaners to remove biofilm and other deposits.

3)Certain areas of the coil may have more deposition than other areas.  A gentle flush of water through the coil may identify areas that are particularly fouled.

4)Cleaning from the bottom of the coil to the top is recommended. Multiple cleanings of the coil may be necessary due to heavy deposition.

5)After completion of cleaning, again run the hose through the coil to see if water now flows freely through areas previously found to be restricted.

6)Coil cleaners may be either acid, neutral, or alkaline in nature.  Many manufacturers call neutral pH or alkaline pH cleaners “non-acid” cleaners. Both acid and alkaline cleaners will attack coil fins, causing pitting and other corrosion. To reduce this problem, coils must be copiously rinsed with water to neutralize any chemical residual left on them.

7)Sanitize the coils using an iodine-based anti-microbial.

8)Apply a molecular coating to the coils, such as our product First Strike Micro Coat, to reduce future build up.

Properly cleaning coils as part of a preventative HVAC maintenance program can save a building owner thousands of dollars.

Product Spotlight: The Unseen, Often Ignored HVAC Problem that is Draining Your Wallet

Dirty coils reduce the system’s ability to cool your home and cause the system to run longer, increasing energy costs and reducing the life of the equipment.” Energy Star Maintenance Checklist http://www.energystar.gov/index.cfm?c=heat_cool.pr_maintenance.

During normal operation of an HVAC system, contaminates and particles enter through the air and build up on the coils. This buildup hampers the system’s effectiveness and shortens equipment lifespan. Constant cleaning of coils by personnel is expensive and time-consuming, and often results in a trade off. Either more money must be spent on preventive maintenance, or more money will be spent on energy costs and replacement.

For this reason, having dirty HVAC coils is seen as unavoidable. For treatment, there are numerous coil cleaners including non-acidic, non-caustic and foaming. While all clean the coils at different levels of effectiveness, they essentially are only momentarily effective. Once the system starts back up, buildup begins again until the next cleaning. For this reason, an effective maintenance plan includes applying a preventive product that deters contaminate accumulation.

At CRT, we have developed the following products to protect HVAC systems from unnecessary buildup. By using our Micro Coat Product Line, both condensate and evaporator coils can remain clean and buildup free, prolonging the time between cleanings and saving both time and money.

First Strike Micro Coat

First Strike Micro Coat is an independently GREEN certified coating designed to protect against unnecessary labor and costs. First Strike Micro Coat reduces recurrent deposit buildup on HVAC evaporator coils by providing a clear molecular layer, or micro coating, of protection. Once cleaned, evaporator coils remain clean up to one year or more.

Coil Shield

Coil Shield is a coating designed to protect condenser coils from corrosion. In high salt and industrial areas, corrosive elements are pulled into HVAC condensers. This causes the system to run inefficiently, and eventually leads to condenser replacement. Coil Shield provides a clear molecular layer, or micro coating, of protection that lasts up to one year or more.

Remember, we value your experiences and welcome any comments you may have.
