What Is Condensation?

How many of us have went out of our way to shop for a glass, tumbler, or cup that will not “sweat”. There is nothing I dislike more than grabbing a cup with water droplets! These water droplets/sweat are also known as condensation.

Condensation can be in many more places than just our favorite tumbler. One major place of concern of condensation is in the HVAC System.

Condensation occurs when water vapor in the air comes into contact with something cool. Molecules slow down and get closer together & the gaseous water vapors turn back into liquid water drops (condensation). Seems kind of harmless on our cups but in an HVAC System this can cause so much damage and cost a great deal of money.

Years ago, Lynn Burkhart- President of CRT, visited a very prestigious resort in Florida. An esteemed guest had a not-so-pleasant experience in the resort.  There was a leak on the floor above, this leak damaged several expensive belongings of said guest. Can you imagine the frustration of the guest and embarrassment of the resort?


Do you know how this leak occurred? That’s right. Condensation from the HVAC’s drain pans had overflowed and leaked into the room, from the ceiling. Yikes! There is never a good reason for water to emit from the AC Unit. That is a true sign that the unit needs some TLC (Tender Loving Care). Whether it’s maintenance, repairing, or replacing. 

PM (Preventative Maintenance) is important to the health of your HVAC system. A checkup once or twice a year will help to detect & prevent an issue before it occurs. 

You can also be proactive by providing a time-released drain pan treatment PanGuard (Certified Green) or Algae Guard (EPA Registered) to keep your drain clean & free from over flows.

We’d love to hear any condensation stories you have. Please give us a call, comment, or simply shoot us an email. We look forward to chatting with you.

Product Spotlight: Airing Out Your Dirty Laundry (Socks)

Practically all items inside of buildings contribute to indoor air quality. Everything from carpeting to office equipment release gases and particles known as volatile organic compounds (VOCs). However, the most referenced cause of indoor air quality concerns by tenant and workforce populations is the HVAC system. These concerns are a result of the strength and frequency of undesirable odors being disseminated by HVAC systems.

Contaminated outside air, bacteria and mold are thought to contribute to many health issues. Unfortunately this is quite common, as the interior of HVAC systems provide the perfect growth environment for spores to become active. Along with providing a dark, temperature-controlled area, HVAC systems remove moisture from the atmosphere providing mold spores with water, and remove dirt and debris providing mold spores with food.

Controlled Release Technologies, Inc. (CRT) has developed the following solutions to help buildings maintain positive indoor air quality, and avoid odor problems originating in the HVAC system. By using these products, air handler units can remain clean and sanitized. Additionally, the time between cleanings and the life of the unit itself can be increased, and the chance of poor indoor air quality can be dramatically decreased.

The Dirty Sox Kit is an annual, three-step application process developed by CRT that rids HVAC air handler units of odors by cleaning, sanitizing and protecting the evaporator coil. It is generally applied in the fall or winter months, and in systems where Dirty Sock Syndrome is thought to be present.

Dirty Sock Syndrome is a term coined by industry experts to describe unidentifiable odors which building occupants equate to the smell of dirty laundry or a gym locker room. Dirty Sock Syndrome is believed to be a result of bacterial growth on HVAC evaporator coils. The problem is generally limited to heat pump systems, but may be noticed in other system interiors.

Dirty Sock Syndrome is prevalent in buildings located in hot, humid climates, where there is a constant supply of moist air exasperating the problem. Because a microbial can grow quite rapidly, the emission of odors increases over time.

Follow these steps when applying Dirty Sox Kit:

  1. Apply Instant Powder Kegs coil cleaner to clean the evaporator coil of deposit buildup.
    Instant Powder Kegs is a concentrated cleaning powder, that is mixed with water at the job site, saving users expensive and unnecessary shipping charges. Instant Powder Kegs removes dirt and odor-producing build up that hinder the efficiency of HVAC systems.
  2. Apply Fast Attack to sanitize the coil, and remove any odor-causing algae, fungus, bacteria or mold.
    Fast Attack is an EPA-registered, concentrated antimicrobial that cleans as it sanitizes. Iodine was chosen as the active ingredient, as its effectiveness is well known and widely used in hospitals and laboratories.
  3. Apply First Strike Micro Coat to the coil surface to protect against future buildup of dirt and contamination.
    First Strike Micro Coat provides a clear molecular barrier (less than one micron), that does not inhibit heat transferability. Because First Strike Micro Coat has been extensively evaluated, it performs without maintenance attention for a year or more. This decreases redundant labor costs and coil cleanings, and keeps coils performing at optimal energy usage.

Technical Corner: The Nature of Chemical Solubility Part Two

Users who put in chemical “tablets” in the hope of treating such water collection pans are often disappointed, with unpredictable performance.  This happens because tablets dissolve quickly, with no long-lasting abilities. Wax-type products are slower to dissolve, but release only a small amount of ingredients, which are usually not enough to handle debris present in the condensate pan.

Another problem with using tablets and wax-type materials for pan treatment concerns biological control. Biological control is necessary in many water collection pans, and a certain minimum amount of antimicrobial is essential. In some cases, this amount is over 400 milligrams per liter of water. Liquids, tablets and waxes cannot maintain these antimicrobial treatment requirements for long, if at all, and quickly become ineffective.

Just how does the controlled release process work?  

Having a controlled release product for HVAC water collection pans is like having a built-in worker, one who works 24 hours a day, seven days per week, just cleaning the condensate pan. Instead of hours of workability, product workability lasts multiple weeks and months. This eliminates labor, ongoing service work and pan overflows, all while keeping odors away and maintaining crystal clear water in the pan; as it should be.

Controlled Release Technologies, Inc. developed and manufactured the first workable product of this type for HVAC systems in 1986.

CRT’s Timed Release Products produce an initial high treatment level, and then level out to a consistent and constant release of cleaning and dispersal ingredients – 24 hours a day, 7 days per week. After placing the product in the water collection pan, no additional labor or personnel are needed to maintain product effect. Lasting up to six months, the pan is constantly kept in a clean state, eliminating odors and overflows.

Adding a controlled release product such as Algae Guard to an HVAC preventive maintenance program is one of the best decisions one can make. The products maintain unit hygiene, stop pan overflows, and reduce work force costs.

CleanAC Kit
The CleanAC Kit is an annual, four-step application process that rids HVAC air handler units of buildup and accumulation by cleaning, sanitizing and protecting both the evaporator coil and condensate pan. It is generally applied in the spring or summer months when condensate pans accumulate moisture, and in systems requiring a thorough cleaning.

The first step is to apply Instant Powder Kegs coil cleaner to clean the evaporator coil of deposit buildup. Instant Powder Kegs is a concentrated cleaning powder, that is mixed with water at the job site, saving users expensive and unnecessary shipping charges. Instant Powder Kegs removes dirt and odor-producing build up that hinder the efficiency of HVAC systems.

The second step is to apply Fast Attack to sanitize the coil, and remove any odor-causing algae, fungus, bacteria or mold. Fast Attack is an EPA-registered, concentrated antimicrobial that cleans as it sanitizes. Iodine was chosen as the active ingredient, as its effectiveness is well known and widely used in hospitals and laboratories.

The third step is to apply First Strike Micro Coat to the coil surface to protect against future buildup of dirt and contamination. First Strike Micro Coat provides a clear molecular barrier (less than one micron), that does not inhibit heat transferability. Because First Strike Micro Coat has been extensively evaluated, it performs without maintenance attention for a year or more. This decreases redundant labor costs and coil cleanings, and keeps coils performing at optimal energy usage.

The fourth step is to place a PanGuard timed-release strip in the HVAC condensate drip pan. PanGuard is a blending of wetting agents and dispersants that eliminates clogs and overflows due to deposit accumulation. By protecting the unit using a timed-release product, it will continue to work even after staff have completed maintenance, for up to six months. This in turn, protects against costly water damages that can occur.

The CleanAC Kit is available in three different sizes for both residential and industrial needs. These sizes are 3-5 tons, 10-15 tons and 20-25 tons. By using this kit annually, one can be assured that HVAC air handlers remains clean and protected year round.
