Duct, Duct... Mold?

When your heating and air duct, or equipment, is installed inside the crawl space, the temperature of the air is being delivered. The duct work is around 45 to 55 degrees. When that mixes with the warm (100% +) humid air, then, condensation is the end result. Some homes have drainage issues or rain water run-offs that go under the foundation walls, and the moisture starts to mix with warm humid air. Either way, it results in mildew growing in the crawl space - which will result in heavy molding if nothing is done to stop the issue.

To correct the issue, you have to do 3 very important things:

Install a Moisture Barrier

Installing a plastic moisture barrier (minimum of 6 mil. thickness) will lay on the ground. First, you need to clean any debris from the crawl space. Then, lay the material down on the surface. Roll the plastic up the wall 12”. Also, cut around each foundation pier. Roll the plastic up 12”, as well. Then, foam the plastic to the walls and piers to keep moisture from seeping up the moisture barrier. 

Install a WHOLE House Dehumidifier

We used to tell our customers to go to your favorite big box store and purchase a 65-pint dehumidifier (a window unit). Now to our knowledge, they unfortunately break a lot. So, now we rely on a Honeywell DR65. This is a whole house machine that goes in the crawl space and suspends from the floor joist. We duct the system to each end of the crawl space to warm and dry up the moist areas. We install an independent drain line either in the sewer line or outside away from the foundation.

Seal Your Duct Work

Once you have completed steps 1 and 2, then you are ready to seal your duct work. There are two rules for doing this. You can seal the duct work by removing the duct wrap insulation and painting the seams with a liquid mastic. Then, install new duct wrap insulation around each duct. Some customers decide to replace the entire duct system and seal it completely while installing the new duct work.

OZ the Wizard of Clean

Ozone's Effective Applications:

•  Ozone kills bacteria, viruses, molds, spores, and mildew
• Ozone destroys chemical contaminants such as: aldehydes, which can be discharged from paneling, carpets, insulation, paints, stains, and plastics
• Ozone eliminates odors from cigarettes, cigars, pets, mildew, airborne molds, locker rooms, and shoes.

Some Area Application:

• Hotels
• Offices
• Housing
• Dental and Doctor Offices
• Basement and crawl spaces
• Kitchens
•  In Air-Treatment
• Pet Areas

Why Should I Add Attic INSULATION?

If you live in the south you know all about the hot summers and somewhat cold winters. Insulation is a filter to slow the heat or cold air down. This predicts how excessive your utility is. Most all energy rater in the country recommends from 6-14” minimum. This will range from R-19- R38. The R factor is a term which is the thickness and the rate of air leakage. Our team is paramount at installing your insulation to make your home energy efficient. We can also add to your existing attic. We can take a R-12 attic to a R-38 attic and save $ hundreds. If you are in the TVA area there are rebates available. 

TVA Rebates

Attic insulation - $200.00

Are Pleated Filters as Efficient as Non Pleated Filters?

The pleated filters that you see at your home centers or big box stores sounds like the filter that everyone thinks is the best filter. They see the sticker that reads 90 day filter. Most homes cannot wait 90 days to get changed. Many homes ductwork will not accept the pleated filters. Bacically the pleat is very thick and cannot breath after the first 15 to 30 days.The department of energy recommends to use the non pleated filters. They cause the indoor fan motor use more energy. That is harder on the indoor blower motor and the compressor.

Sense the compressor is the heart of the system it is very critical to the system. When the duct work is designed properly you can use a 4" air cleaner that fits in a air cleaner. This is efficient to the system. Talk to your heating and cooling professional about what filter works best for your home. Fore more information visit our website at harbinair.com/filters.

Geothermal Education

Step 1:  Drilling the Wells

The number of wells to be drilled is determined by the heat load of the structure, the nature of the soil on the property and the water table.  This is determined on a case by case basis.

Step 2:  Grouting the Wells

Grout or other cement product is then pumped into the well hole to secure the loop.

Step 3:  Installing the Header for Vertical Ground Loops

The header manifold connects the wells to each other in series and brings the loop into the building,

Step 4:  Installing Ductwork, Piping and Geothermal Heat Pumps.

The ductwork for a geothermal installation is identical to an air cooled system.  The geothermal heat pump uses heat pump technology but instead of using air to transfer heat, it uses water from the well loops.

Step 5: Flushing and Purging

Before the system can be operated, the loop and well system must be flushed of all impurities.  The water in the loop is then treated to prohibit organic growth and chemical scale.

Step 6: Installing the Desuperheater

A desuperheater uses the heat generated in the refrigerant tubing of the Water Source Heat Pump to preheat the hot water of the home, further increasing efficiency.
