A/C Coil Cleaning – an Art or a Science?

As a busy service technician, what’s often the last thing on your to-do list? For some, it’s cleaning the coils on HVAC units.

Why? It’s messy work, can take up your time, and often feels unnecessary. For those reasons, coil cleaning isn’t usually the first thing that comes up in HVAC conversations.

Over the years, we’ve seen several magazine articles on how to clean coils. More than a dozen contractors have done full-scale tests on coil cleaning. Some have even pulled the entire coil out of the unit and immersed it in cleaning solutions. It’s easy to say that coil cleaning is simple and of little consequence. But nothing could be farther from the truth.

In next month’s newsletter and here on the blog, we’ll share with you the best and easiest ways to clean coils, the benefits for you and for the owner, and all kinds of other important factors.

Do you have questions about coil cleaning? How do you clean coils? 

All questions and comments are welcome!

Feature: HVAC Hess – Fact Sheet on the Importance of Cleaning Coils

My inspiration of this blog came from HVAC HESS (The Heating, Ventilation and Air Conditioning High Efficiency Systems Strategy) a ten year strategy under the Nation Strategy on Energy Efficiency (NSEE) that aims to drive long term improvements in energy efficiency of HVAC Systems Australia wide. Their goal is to educate, inform, and encourage energy efficiency in the HVAC Industry. A series of the HESS fact sheets can be found at http://www.ee.ret.gov.au/energy-efficiency/non-residential-buildings/heating-ventilation-and-air-conditioning-hvac/hvac-hess-fact-sheets

I wrote a blog a few weeks ago about the price of our Powder Keg being so low. What I didn’t think to mention is why it is so important to clean coils. My ex-husband and several other contractors that I know just rinse their coils off with water. I am here to tell you the reasons why actually cleaning your coil with a cleaner is important in more ways than one! All of what I wanted to say, I found in an awesome article that describes it ALL!

“ Finned coils are used in a number of different applications in HVAC systems to transfer heat either into or out of air streams.

There are two basic types of coils:

1. Condenser coils – Condenser coils transfer heat into a space. Refrigerant vapor is forced into the coil under pressure, condensing the refrigerant into a liquid, which results in the rejection of heat across the heat exchange surface.
2. Evaporator coils – Evaporator coils do the opposite to condenser coils. Liquid refrigerant is pumped into a low pressure coil, causing the refrigerant to evaporate into a vapor, absorbing heat across the heat exchange surface in the process.

Over time the surfaces of these coils can become dirty as the air moving over the coils can contain dust, dirt, pollen, moisture and other contaminants. A build-up of contaminants decreases the available surface area for heat transfer, reducing the energy consumption and poor system performance. It is important that air conditioning coils are regularly inspected and indoor air quality; a fact that has led to regular coil cleaning becoming a regulatory requirement in certain circumstances and provides guidance on cleaning.”

Here are all the very important points this article by HVAC HESS hits on regarding why Cleaning Coils is important:

-Energy Efficiency
-System Performance
-Equipment Life Cycle
-Indoor Air Quality
-When and How to Clean

Keep in mind that the air you breathe is directly from your coils. I have heard several horror stories about locations of AHU’s that were very neglected. One place – a hospital – so neglected that their were dead animals in the drain pans. The place that should be cleaner than any other place had people breathing the unimaginable. So I pose the question, what are you really breathing?

Company News: Going through Changes

The one constant in life is change is inevitable. In regards to your business, the way change is handled and approached makes all the difference. Recently at CRT, we have seen a change in how some of our office positions are structured, allowing people to specialize more in their fields, and thus serve our clients and potential clients better.

Kristen Bean has recently been appointed to Assistant Marketing Director. This new position reports directly to the Marketing Director and oversees all Client Services, Sales and Publicity departments and initiatives. Her goal is to improve relationships through streamlining internal initiatives and integrating all external communication.

Shandi Maddox has been elevated to Sales Manager. As the title implies, she is now in charge of all prospect inquiries. Chasity Walker is now our Publicity Manager. Her position handles CRT’s social media and internet presence, as well as special events.

Finally, CRT would like to welcome the newest member of our family, Zeni Byers. Zeni is our Client Support Manager, and the main point of contact between CRT and you, the people we value most. Before joining CRT, Zeni spent many years both training customer service representatives and leading by example. She is a single mother of one and native of Shelby, NC. When not at work, she enjoys cooking, dancing, singing and helping others.

As a way to introduce herself, and display her helpful nature, Zeni will soon be contacting our clients regarding our Quick Cleaning Products. Regular coil cleaning and preventive maintenance allow the HVAC system to quickly obtain and maintain the desired temperature and humidity levels. Because HVAC systems account for over half of the energy used in commercial buildings, allowing the system to work less to cool the building results in significant savings.

Give Zeni a call today at 1-800-766-9057 to learn more about our Quick Cleaning Products, both our coil cleaner, Instant Powder Kegs, and our HVAC system sanitizer, Fast Attack.

Tips From The Girls: “Importance of Keeping it Clean”

For you to live comfortably, and to keep your HVAC unit running effectively, it is important to maintain and clean your unit.

The coil of your HVAC system is one of the most important things to keep maintained and clean. A dirty evaporator coil decreases air flow, resulting in reduced heat transfer and a decrease in dehumidation. In turn, this decreases the life expectancy of the HVAC unit due to the increased heat while it runs.

Dirty coils can throw the whole cooling/heating process completely off track. Dirty coils cause compressors to run longer and work harder, leading to higher energy usage and costs. Who wants that?

Here at CRT, we offer products specifically to solve these problems. Fast Attack is for sanitation purposes of the unit [excluding any duct work). Instant Powder Kegs is for the cleaning of the coils, and comes in a powder form, making it easy to transport and apply. Also we have Clean Bond, a powerful cleaner and degreaser that picks up residual oils and other particles.

Keep your costs low and your environment healthy by keeping your coils in top condition. If you are on the go a lot, and do not think about the “out-of-sight” issues, you may find it important to have an annual energy assessment conducted to ensure that everything is running correctly. In fact, we recommend having one done before using CRT products, and then again a year later. We know you will be pleased with the results.
