Product Spotlight: Reduce HVAC Energy Consumption Through Proper Cleaning

HVAC systems account for over half of the energy used in commercial and residential buildings. For this reason alone, it is important to keep energy expenditures to a minimum. Excessive energy use by the HVAC system is usually due to improper or irregular maintenance of the equipment. Therefore, a regularly scheduled cleaning and maintenance plan helps sustain HVAC equipment while reducing energy consumption and improving energy efficiency.

One of the main causes of HVAC energy consumption is due to thermal discomfort. Occupants are dissatisfied with the buildings thermal temperature and adjust the thermostat, increasing energy costs. However, proper cleaning and preventive maintenance allow the HVAC system to quickly obtain and maintain the desired temperature and humidity levels. The HVAC system works less to heat or cool the building, which satisfies both occupants and building owners.

At CRT, we have developed the following products to clean HVAC systems. By using our Quick Cleansing Product Line, coils, condensate pans, and system interiors remain clean and buildup free, saving users money and making HVAC systems more efficient.

Fast Attack
Fast Attack is an EPA registered, concentrated iodine sanitizer. Iodine was chosen as the active ingredient, as its effectiveness is well known and widely used in hospitals and laboratories. Fast Attack quickly and conveniently cleans and sanitizes the interior surfaces of HVAC systems, removing odor-causing algae, fungus, bacteria and mold.

Instant Powder Kegs
Instant Powder Kegs is a highly concentrated cleaning powder that removes efficiency-hindering buildup from all HVAC coils. Unlike other coil cleaners, instead of diluting down the product, Instant Powder Kegs is mixed up with water to the desired strength. Instant Powder Kegs will not separate or leak, and is easily transportable due to its compact nature.

Clean Bond
Clean Bond is a concentrated liquid cleaner that is also used when preparing HVAC air handler units for resurfacing. When diluted, Clean Bond cleans and removes efficiency-hindering buildup and grease from all HVAC system metal surfaces. When concentrated, Clean Bond inhibits flash rusting, and is formulated to act as an additional adhesion agent.

Technical Corner: Properly Applied Coatings Equal Big Savings for Commercial Buildings

Recently, the National Association of Duct Cleaners of America requested I write an article for their association magazine, DucTales. The following is an excerpt from part 2 of that article:

Many managers and owners don’t realize that effective cleaning and coatings can provide and immediate return, lowering their energy bills and extending the life of their equipment. Cleanings and coatings delay need for the replacement of expensive HVAC equipment.

Advanced technology and maintenance methods are now available to help owners effectively manage HVAC expenditures, which can add up quickly each month. According to ASHRAE, it’s possible for 50 percent of more of building’s energy costs to relate directly to the HVAC system. Most managers and owners are aware of the impact HVAC systems have on energy costs, but are unaware that new methods are available to offset these expenses.

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

Business Survival and Sustainability: Safeguarding Tangibles

Once steps have been taken to maintain electronic data, it is time to safeguard other, more tangible items. This is a prime opportunity to get to know your banker better, because now you need a safe deposit box. You may wonder why you should you store items off site. Well, what if the roof falls in, there is a flood, or some other occurrence that make it impossible to retrieve tangibles? It does no good keeping these items in an office safe. The bank vault is your best bet. Here is a list of ten items that need to be included:

1. A complete set of labeled keys for all doors, sheds, vehicles, file cabinets, etc;

2. An up-to-date book of passwords;

3. Checks, checks and more checks, along with account and telephone numbers;

4. All insurance policies;

5. A quarterly physical back up of your accounting computer, if it is not completely backed up at the accountant’s location;

6. A list of all business property, along with pictures, updated annually or whenever a major purchase is made;

7. A back up of client files;

8. Your up to date business and marketing plan;

9. Any papers that are not replaceable, or would be difficult to replace, such as licenses, patents, formulas, agreements, etc. (You can make good color copies of things you have hanging on the walls and use them, while storing the originals in the deposit box);

10. The plan for how you will deal with disasters – The Business Continuity Plan (that’s what we are building here, step by step).

Once you have gathered together all of these items, make sure to get a safe deposit box that is big enough. In fact, get the biggest one you can, because there always may be stuff you need to add to this later.

Join me next month as we continue to discuss building a Business Continuity Plan, and check out our other posts dealing with the HVAC industry. As always, your experiences are what makes this blog interactive, so your comments are welcomed and encouraged.

Fall Sicknesses and their Relationship to Heating and Cooling Systems

A source of biological spores

Many people typically get ill during the Fall season.  Although there are many reasons one might get ill, a seldom thought of culprit may lie within a buildings heating and cooling system.

Out of Sight – Out of Mind

Owners seldom pay attention to the insides of their HVAC system.  If it works, then that is the end of any involvement with the system by owners or maintenance staff.

But HVAC systems get dirty.  Damp and dark interiors are perfect breeding grounds for mold and bacteria.  It is common for fungal and bacterial matter to build up within the HVAC system.  Growth and amplification of fungus and bacteria most often occurs during the summer operating months where humidity are high.   Growth can be so substantial that the condensate or water collection pan within the HVAC unit becomes a reservoir for dirt, and biological matter.  The result is what is sometimes called a “biological broth” comprising fungal (mold) growth and debris that passes around or through air conditioning filters.

Once you have had the occasion to see this unhealthy soup, you probably won’t want to see it again.

Operational Problems Caused by Microbes

This same collection of microbials often causes the drain to stop up in the HVAC unit, with the result of water overflowing onto carpet or sometimes into the floor below.  Either way, the result is a nasty situation.

Microbiological growth occurs in the  summer months where warm temperatures, nutrients and moisture abound.    But is in the  iFall they are particularly troublesome.

It is at this time of year that the cooling system is turned off, and the heating system starts up.  Fungus has already dried up within the water collection pan, coils, and interior surfaces.  When viewed, the water collection pan which a few months previous looked nasty, now looks just dirty with a small amount of debris left.

The average thought is: “Well, thank heavens!   That mess is gone and now I am free from it!”

Nothing could be further from the truth however.

Mold or fungus goes into a dry spore form when there are no nutrients or water to promote its growth.  Microbial spores are very small objects, and individually are below the limits of human visibility in most cases.  What one sees are millions and more spores grouped together.  Some estimates have put the numerical count in the trillions of spores depending upon the extent of the growth.

Spores are  light, and are easily disturbed.  When disturbed they get released into the air flow going to occupied areas.  Often just starting up an air handler or system is enough to shake loose several thousand or more spores.   SIzes of spores are such that they may easily become breathed into ones lungs as well as alight onto room surfaces.

Many of these spores are less than 5 microns (30 microns is the lower limit of human visibility).  Particles of this size easily penetrate into lungs.

Allergic illnesses can develop resulting in some of the following symptoms:  sneezing, fatigue, headaches, asthma and others. The phrase “Sick Building Syndrome” is associated with this type of contamination.

Is there a solution to this?

While there is no broad method of handling all contaminants, there are ways of addressing deposits within the HVAC system.

Essentials of Handling

These involve keeping the microbial contamination out of the condensate water collection pans in the HVAC system continually to avoid build-up in the first place.  Controlled Release Technologies developed the first timed-released solution to handle this problem without constant attention in 1986.  Since then, remarkable technological developments have been made.

You can read about how some of these solutions can help your air handlers  be kept clean without constant maintenance attention in one of our upcoming blogs.   We value your experiences with how dirty air handling units can affect occupant comfort.  Comments are always appreciated.

Technical Corner: Cleaning and Coating HVAC Systems to Improve the Bottom Line

Recently, the National Air Duct Cleaners Association requested I write an article for their association magazine, DucTales. The following is an excerpt from that article:

Most often, owners or managers of buildings have little forewarning that an air handler may be on its last leg. Frequently, a HVAC owner receives an unexpected notice that an air handler needs to be replaced, which puts a strain on the annual budget. Additionally, it is usually the case that when one air handler needs to be replaced, the others are not too far behind, as all were probably installed at the same time.

The lifespan of a HVAC unit has a tremendous impact on the overall costs per year of ownership. A unit that is viable for 30 years will offer a better return on investment than a unit that only lasts 20 years, as long as efficiencies are maintained. Coatings can and will improve the cost of ownership through useful life extension, and can be a significant driving force in management electing to opt for this preventive measure. It is no secret that refurbishing units, rather than replacing them, can save tens or hundreds of thousands of dollars for the owner.
