August 18, 2021 Just when it seemed some normalcy was returning, in walks Covid Delta Variant! From the CDC website:
The Delta variant causes more infections and spreads faster than early forms of SARS-CoV-2
The Delta variant is more contagious: The Delta variant is highly contagious, nearly twice as contagious as previous variants. Some data suggest the Delta variant might cause more severe illness than previous strains in unvaccinated persons. In two different studies from Canada and Scotland, patients infected with the Delta variant were more likely to be hospitalized than patients infected with Alpha or the original virus strains. Unvaccinated people remain the greatest concern: Although breakthrough infections happen much less often than infections in unvaccinated people, individuals infected with the Delta variant, including fully vaccinated people with symptomatic breakthrough infections, can transmit it to others. CDC is continuing to assess data on whether fully vaccinated people with asymptomatic breakthrough infections can transmit. However, the greatest risk of transmission is among unvaccinated people who are much more likely to contract, and therefore transmit the virus. Fully vaccinated people with Delta variant breakthrough infections can spread the virus to others. However, vaccinated people appear to be infectious for a shorter period: Previous variants typically produced fewer virus in the body of infected fully vaccinated people (breakthrough infections) than in unvaccinated people. In contrast, the Delta variant seems to produce the same high amount of virus in both unvaccinated and fully vaccinated people. However, like other variants, the amount of virus produced by Delta breakthrough infections in fully vaccinated people also goes down faster than infections in unvaccinated people. This means fully vaccinated people are likely infectious for less time than unvaccinated people.Masks
Given what we know about the Delta variant, vaccine effectiveness, and current vaccine coverage, layered prevention strategies, such as wearing masks, are needed to reduce the transmission of this variant At this time, as we build the level of vaccination nationwide, we must also use all the prevention strategies available, including masking indoors in public places, to stop transmission and stop the epidemic. Vaccines are playing a crucial role in limiting spread of the virus and minimizing severe disease. Although vaccines are highly effective, they are not perfect and there will be vaccine breakthrough infections. Millions of Americans are vaccinated, and that number is growing. This means that even though the risk of breakthrough infections is low, there will be thousands of fully vaccinated people who become infected and able to infect others, especially with the surging spread of the Delta variant. Low vaccination coverage in many communities is driving the current rapid and large surge in cases associated with the Delta variant, which also increases the chances that even more concerning variants could emerge. Stay safe and well everyone!
Let’s explore the causes of condensation (sweat) on air conditioners and its effects!
What Causes Condensation on Air Conditioners? The same process that causes a cold glass of iced tea to form water droplets on its exterior in the summer causes condensation on your air conditioner. As your system’s evaporator coil cools warm air that passes over it, absorbing heat and moisture from the air, condensation forms. As this condensation drips down, it collects in your system’s drain pan and (if it’s properly maintained and not clogged) through the condensate drain line and out of your home. Can condensation hurt my AC system?
Condensation is normal for properly running air conditioning systems. Excess condensation, like sweating ducts and drips from outside the unit cabinet indicates a problem with your unit and points to an HVAC system issue that requires emergency HVAC repair service. Without prompt attention, excess condensation could overwhelm your air conditioner’s drainage system, causing damage within your home. This damage can range from high humidity levels that lead to mold and mildew proliferation and spots, to structural damage from drainage water that accumulates and puddles.
What HVAC system issues result in condensation?
Condensation Pan Problems - Your A/C unit condensation pan collects condensate water from the evaporator and sends it to an external drain however over time condensate pans can crack which can lead to water running through the unit and spilling out causing damage to the unit and to the home.
Clogged or Dislodged Drain Line - If bacteria and fungus build up in the drain line, it can become clogged. It is also not uncommon for drain lines to become dislodged or outdoor drain line components to become obstructed. When this happens, your condensation pan will overflow, causing water to leak into your home.
Broken Condensate Pump - In homes with basements, a pump assists in the removal of water from your system. If this pump breaks, water will leak into your basement. Because this area of the home is not commonly frequented, extensive damage could occur before you notice drainage issues.
Dirty Air Filter Leading to Frozen Evaporator Coil - Dirty home air filters don’t facilitate adequate airflow over the evaporator coil. Without proper airflow, the coil gets too cold and freezes. When this ice melts, dripping into the condensation pan, it can overflow.
Low Refrigerant Charge - If your system is low on refrigerant, this can also cause the evaporator coil to freeze, which likewise can result in an overflowing condensation pan as ice melts. Other effects of condensation include CORROSION!

Their headquarters in Columbus, Indiana was built in 1983, on land that formerly served as the Columbus rail yard, featured a new precast concrete structure built around the original building, a former Cerealine Factory built in 1867. The facility had 18 aging HVAC/R units installed around 1994 that were losing heating/cooling efficiency. These units were custom built for Cummins’ applications and it was cost prohibitive as well as wasteful to replace them. After much research, they decided to refurbish the current units with upgraded energy efficient parts and protect the equipment with Bronz-Glow’s durable, sustainable products.
As part of their 100-year anniversary celebration, Cummins, Inc. launched a 7-year refurbishment project, commencing in 2018.
Bronz-Glow Technologies, Inc. has been chosen to apply its Proprietary Bronz-Glow Husky Primer and Husky Coil Coat as a Protective Coating to prevent further corrosion to their HVAC units.
Goals of this sustainability initiative included reusing materials, reducing energy costs 3-5% and refurbishing all of the rooftop HVAC units to extend the life of these systems for another 10+ years. According to Cummins.com, the company is committed to zero carbon footprints and this proposal would help them reduce waste and energy usage to meet their Planet 2050 goals.
Our Customer Service, Field Service and Safety Teams met with Cummins Engineers and Project Managers and determined the best solution was to clean and coat the existing coils with Bronz-Glow Proprietary Husky Primer and Husky Coil Coat after the refurbishment was completed.
Using Avetta Supply Chain Management Software, Cummins vetted Bronz-Glow and trained each of our 3-person field coating teams in their safety protocols prior to arriving onsite.
Later in the project, Cummins added cabinetry protection, using our SPC blend coating containing a 10-year UV Protectant, to these rooftop units to protect this equipment from the elements of weather and UV deterioration.
Several teams of Bronz-Glow Technologies’ expertly trained Technicians travel to Indiana and spend a week on each HVAC unit cleaning, priming and coating each coil and cabinet according to the project timeline. Bronz-Glow is coating 2-4 units a year on site over the next few years with our 15,000-hour salt spray tested coatings.
Cummins, Inc. shows a measurable savings in energy costs from 5 years ago due to the changes they are making with this refurbishment project. Even though energy prices have risen during this time, Cummins, Inc. is continually reducing their energy consumption, saving money and increasing the reliability of the HVAC equipment necessary to keep their equipment production running smoothly and further protecting our environment. Bronz-Glow’s patented coating, a polyelastomer blend with less than ½% heat transfer loss, extends the life of industrial equipment and in NASA testing, actually improves HVAC efficiency over time due to corrosion prevention.

We hope it's your best year ever. The Black Dot One day, a professor entered his classroom and asked his students to prepare for a surprise test. They all waited anxiously at their desks for the exam to begin.The professor handed out the exams with the text facing down, as usual. Once he handed them all out, he asked the students to turn over the papers.To everyone’s surprise, there were no questions–just a black dot in the center of the paper. The professor, seeing the expression on everyone’s faces, told them the following:“I want you to write about what you see there.” The students,
confused, got started on the inexplicable task.At the end of the class, the professor took all the exams, and started reading each one of them out loud in front of all the students.All of them, with no exception, defined the black dot, trying to explain its position in the center of the sheet. After all had been read, the classroom silent, the professor started to explain:“I’m not going to grade you on this; I just wanted to give you something to think about. No one wrote about the white part of the paper. Everyone focused on the black dot – and the same thing happens in our lives. However, we
insist on focusing only on the black dot – the health issues that bother us, the lack of money, the complicated relationship with a family member, the disappointment with a friend.The dark spots are very small when compared to everything we have in our lives, but they are the ones that pollute our minds. Take your the eyes away from the black dots in your lives.Enjoy each one of your blessings, each moment that life gives you. Be happy and live a life filled with love!”

Heat Effects on Aluminum/ Copper Coils
by Robert (Bob) Bloom
Corrosive environments have always had an adverse effect on HVAC equipment. Science has studied these and found four main characteristics needed to cause the break-down of all metallic surfaces. MoistureOxygenHeatReactive elements in the environment.These factors vary in the corrosion rates of metals such as Cast Iron (corroding at a fast rate) to Gold (almost no corrosion rate at all). If a metal such as aluminum is in a salt environment, the mixture of salt, humidity and oxygen will cause the molecular structure to break down reducing its ability to transfer heat. When heat is added to the equation, such as direct sun, re-heat operations, defrost modes or simple heat transfer operations, the rate of corrosion is doubled for every
10 degrees F (10° C). With these factors considered, adding a dissimilar alloy such as copper will then cause an electrolysis effect and increase the process of corrosion even more.After long term observation of the above characteristics on air conditioning equipment, it has become very obvious that the rate of corrosion will vary in different components of a HVAC system. Typically, the exterior condenser coil is the most effected due to its direct contact with external elements, however, if there is a reheat coil in the system, the rate of corrosion is higher due to the extensive heat which is produced in that coil. The evaporator coil is always colder than any other coils or components but has a high rate of corrosion due to the constant moisture produced by this component. To read the complete article and learn more on how to decrease the rate of corrosion please click below:Heat Effects on Aluminum/Copper Coils
Did you know keeping a clean evaporator coil will save you more money than you might think?
by Alison Farmer
Your air conditioner is one of the biggest contributors to high electric bills. Even a system with clean coils takes a lot to run.Did you know that a unit that contains dirty coils can increase your bill by 40% and decreases by 30%? Well it can and does so let’s learn some tips and tricks to avoid the unnecessary cost.It is very important that you always have a clean filter in your air handler. A dirty, blocked, or clogged filter will starve the unit of air flow which will make the unit work twice as hard to bring your home to a comfortable temperature.
Just changing your filter once a month can save you a substantial amount. Dirty coils are the biggest problem.Your condenser and evaporator should be cleaned twice a year. I like to do it at the beginning of the hot season and again before the winter months. If you have a heat pump system then your unit runs all year long. In the winter months your evaporator becomes your condenser and it reverses back in the summer months. Therefore your condenser is actually an evaporator too. I know that this can be very confusing so let’s just know that we should keep both of these coils clean.Bronz-Glow offers a variety of coil cleaning product. Husky Coil Guard is a mild detergent that is safe to use on coated and uncoated coils. Evap Zap is a high foaming, rinse free product that is also safe to use on coated and uncoated coils.For directions on properly cleaning your coils please click below:Keep a clean evaporator coil will save you money Why HVAC Coil Coatings?
by Kristen Benton Bepler
Most HVAC manufacturers, distributors, and contractors realize the importance of protection from corrosion by using coil coatings, yet many do not.Hundreds of thousands of pinhole leaks occur over time from corrosion. The causes are from pollutants such as salt-air, household cleaning agents, pesticides, formaldehyde's and more.This corrosion can be seen within weeks after installation but more typically can appear in one to four years.Prevention is the key!Bronz-Glow Technologies, Inc. propriety coatings can alleviate these concerns.If you are already using our coatings, you know!

Bronz-Glow at the Expo
Bronz-Glow started off the New Year in Atlanta at the Annual AHR Expo. It was a great opportunity to meet other HVAC professionals, experience the new products and see the evolving marketplace. This year, we had a unique opportunity to work with one of our Certified Applicators in the booth. Steve Hutcherson from Elite Heating and Air joined us from North Dakota. He was on hand to answer any questions that potential applicators might have and to lend some technical expertise and first hand knowledge to our staff. He kept us laughing the whole week. If you did not meet him, you truly missed someone special. We had a drum made from our coating material and invited several people to show off their talent. Rascal had many fans stop by the booth. So many people wanted to pet him and say hi.
It's That Time of Year...
No, not frosted window panes and painted candy canes on the tree, I am talking about Dirty Sock Syndrome (DSS). You turn on the heat and the smell of gym socks wafts through the house, over powering even the gingerbread just out of the oven. DSS is caused by bacteria roasting on your evap coil, not exactly the makings of a holiday song. Don't cry in your eggnog just yet, there are several things you can do to help combat it. First, if you have a new (or newer) coil, call us to get a quote to dip coat it. Our proprietary coating causes water to drain away, minimizing the growth of the bacteria in the first place. We have the best results in the industry in eliminating Dirty Sock Syndrome. If you can't spare your warm air while we coat your coil, consider trying our Bronz-Glow Evap-Zap foam coil cleaner when we launch it in our online store after January 1st. Simply turn off the power to your HVAC unit, spray Evap Zap uniformly onto your Evaporator Coil and turn the unit back on. The cleaner comes with an extended tube to help coat those hard-to-reach areas. The cleaner is self-rinsing on the cooling cycle and will kill any bacteria that are stealing your holiday joy. (If you are running your heat continuously, you will need to rinse away the cleaner.) Lastly, if your unit is uncoated and you have no intention of coating it soon, call your HVAC contractor to ask about installing a UV light. They are costly and require frequent bulb changes and only eliminate some of the bacteria, not all of it. However, there is no substitute for a Bronz-Glow coated coil in eliminating those humbugs. Call us today for more information or if you just cannot wait until then to try our Evap Zap. "It's that time of year when the world falls in love
Every song you hear seems to say,
'Merry Christmas, may your New Year dreams come true' And this song of mine in three-quarter time
Wishes you and yours the same thing too."
Clean that coil!
Selecting a coil cleaner is important since the cleaner must neutralize and remove deposits on the coil's surface. There are three types of cleaners: alkaline, acidic and surfactants. Which one is right for you? Alkaline cleaners are most widely used in neutralizing acidic coil deposits and are one of the most common types of coil cleaners. The reaction of the cleaner with the coil and dirt causes a foaming action (oxides or hydroxides of aluminum) resulting in the stripping away of minute layers of the base alloy with the soil attached. These types of foaming cleaners are harsh and are usually labeled as corrosive. Usually, this type of cleaner contains sodium hydroxide or potassium hydroxide. These base ingredients are so harsh that they attack the metal, the coil coating and can cause serious injury. Some of these are even known to cause chemical burns on the skin. The other concern when applying these cleaners is the ability to rinse. Most hydroxides tend to cling to the surface unless sufficient wetting agents have been added to the formula to reduce surface tension of the solution. If the solution does not have enough wetting agents and is not rinsed thoroughly from the surface, the residual material can settle at the fin/tube interface and continue to attack the fin. Acidic cleaners are similar to the alkaline cleaners in stripping away or "etching" the metal. When cleaning with an acidic cleaner, you will notice that the surface usually looks brighter. However, it is not necessary to brighten the coil to remove corrosive deposits. The passive oxides on the fin surface are not a detriment to the fins function of heat exchange. In the past, cleaners have included nitric, hydrofluoric, sufuric, or muriatic acids. These are extremely damaging to coil metallurgy and the environment and should be avoided except in an industrial environment. Modern cleaners are much more compatible with the environment and usually have a base of phosphoric or citric acid. These too are labeled as corrosive and should only been used to neutralize caustic deposits or prepare metal surface for coating. Husky Coil Sheen is a phosphoric acid cleaner that we recommend for use on non-coated coils prior to coating. It is also recommended for use in coastal environments to remove and neutralize airborne sea salts that deposit on condenser coil surfaces. Surfactant cleaners are the preferred method of cleaning your coil. Their foaming action reduces surface tension, penetrates dirt, emulsifies and dissolves the solids without attacking the base metal. They are free-rinsing and lift and remove deposits easily. They are safe and easy to apply, are environmentally friendly and rinse quickly. Surfactants are almost always non-corrosive. Husky Coil Guard is is a highly concentrated surfactant cleaner that removes dirt, grime, insect residue, and airborne deposited corrosives without damaging the coil's surface. It is recommended for all Bronz-Glow coated coils and is the only cleaner that will protect your coating warranty. It is safe for both the applicator and the environment.
Coils have planned obsolescence?
Manufacturers of air-conditioning equipment have designed units, particularly coils, to meet higher Seasonal Energy Efficiency Ratio (SEER) ratings. Equipment today is much more efficient than that of just 3-5 years ago. This is gratifying to the owner and power companies as the initial operating demand for energy is reduced. However, the new design of most fin tube heat exchangers (coils) while more efficient is less resistant to corrosion from atmospheric conditions. In developing higher efficiency equipment, manufacturers include typical changes such as increasing the fins per inch, increasing the face area of the coil and adding configured or enhanced fins to increase air flow and create a greater vortex of air passing through the coil for improved heat transfer. The higher fin count and the raised enhancements require thinner gauge aluminum to be employed in manufacturing the fin. Further consider that most modern aluminum is recycled and may contain impurities from the re-manufacturing process. These impurities create anodic cells and intensify the rate of corrosion. Recycled aluminum is not as pure as aluminum derived from bauxite. Coating your coils can eliminate these hot spots of corrosion. These design features make the modern coil even more susceptible to corrosion and entrapment of airborne particles, thus reducing operating efficiency over time. Dirt and other airborne particulates impede air flow through the coil. In corrosive environments, thinner, enhanced fins are more likely to deteriorate from abrasion and corrosion than a coil of older design (14 fpi wavy or plate fin coil made of heavier gauge aluminum). Regularly scheduled coil cleaning removes corrosion and accumulated airborne pollutants such as dirt, soils, insect residue from the coil surface. Proper coil cleaning at regular intervals makes a significant contribution to extending equipment life and is an excellent source of energy conservation for your new coil. Yes, replacing your coils can save you money on your energy bill, but to maximize your savings, you need to protect those coils and keep them clean over the life of the coil.
