The cause of the problem is the growth of mold and bacteria in the drain pan and on the coils. Popular, energy-saving heat pumps are particularly susceptible to this syndrome because their heating cycles are not hot enough to kill the microbes that multiply during the cooling cycle and when the unit is idle. The smell comes from the rich brew of microorganisms that breed on the cooling coil and in the drain pan water.

That will depend on the caretaker. Just like any other pet or animal, they need care--cleaning out the dirty bedding in the coop, keeping it dry and having a clean/dry area of sand or dirt for the birds to take dust bathes in. These practices will all help to keep your birds happy, healthy and odor free. See similar questions...

The tissue lining the upper one-third of the nose contains sensory cells for our sense of smell. Scientists have found that the sense of smell is most accurate between the ages of 30 and 60 years. It begins to decline after age 60, and a large proportion of elderly persons lose their smelling ability. Women of all ages are generally more accurate than men in identifying odors. Some people are born with a poor sense of smell or taste. See similar questions...

In a word, "melanin" is the cause. Ultraviolet light in the UVA range causes melanin to enlarge and turn brown. During the process, dermatologists say a chemical reaction takes place. A natural side effect of the reaction is the aroma. This occurrence is normal whether you've been tanning inside or outside. Some tanning lotions have been designed to minimize or prevent the odor from occurring, but ultimately a shower will remove the odor. See similar questions...

Ozone precursor emission sources are generally divided into two categories: stationary and mobile. Stationary sources fall into two types called point and area sources. Point sources are large, easily identifiable sources such as industrial facilities and operations. Area sources are sources that individually emit smaller amounts of pollutants.

For a flawless and lasting operation of air bearings a clean floor is needed. On a well-prepared surface wear is almost non-existent. Small objects like sand grains, wood chippings, cigarette butts etc. will be blown away by the escaping air film. Paint stains, oil stains, truck tire marks etc. will impair the surface quality, stick to the aircushion torus and increase the air consumption. See similar questions...

Indoor pollution sources that release VOC's (Volatile Organic Compounds) or particulate into the air are the primary cause of indoor air quality problems in homes and offices. Inadequate ventilation can increase indoor pollutant levels by not bringing in enough outdoor air to dilute the emissions from indoor sources and by not carrying indoor air pollutants out of the home. High temperature and humidity levels can also increase concentration of some pollutants. See similar questions...

Modern homes are sealed tightly for energy efficiency. Energy efficient homes are good for your electric bill, but bad for your allergies. Those tight seals trap all kinds of contaminants in your home: pollen that blows in when a door or window is opened, cat dander that hitches a ride on clothing, or chemicals and irritants released by cleaners and perfumes.

Wet and dry fire sprinkler systems are primarily composed of metal pipe, water and trapped or compressed air. Any environment which has oxygen, metal and untreated water in prolonged contact with each other is subject to corrosion (e.g. rust). Bacteria and other corrosion mechanisms can accelerate and concentrate previously occurring corrosion in fire sprinkler systems. See similar questions...

Dirt build-up cannot be prevented and must be removed. Dirty inside a-coils filled with pet hair, construction debris and grime will greatly increase energy costs.Dirty or damaged fins on the outdoor condenser could be costing you money too.
