| Q: |
What types of pollutants are involved? |
| A. |
Air quality is affected by the presence of various types of contaminants in the air. Some are in the form of gases. These would be generally classified as toxic chemicals. The types of interest are combustion products (carbon monoxide, nitrogen dioxide), volatile organic compounds (formaldehyde, solvents, perfumes and fragrances, etc.), and semi-volatile organic compounds (pesticides). Other pollutants are in the form of particles. These include bioaerosols (mold spores, pollen, viruses, bacteria, insect parts, animal dander, etc.); soot; particles from buildings, furnishings and occupants such as fiberglass, gypsum powder, paper dust, lint from clothing, carpet fibers, etc.; dirt (sandy and earthy material), etc. |

| Q: |
What is meant by indoor air quality? |
| A. |
Indoor air quality (IAQ) refers to the impact, good or bad, of the contents of the air inside a structure on its occupants. Good IAQ is the quality of air which has no unwanted gases or particles in it at concentrations which will adversely affect someone. Poor IAQ occurs when gases or particles are present at an excessive concentration so as to affect the satisfaction or health of occupants. It is important to note that the concentration of the contaminant or contaminants is crucial. Potentially infectious, toxic, allergenic or irritating substances are always present in the air. There is nearly always a threshold level below which no effect occurs. |

Don’t wait for an emergency |
| |
Don’t wait for an emergency breakdown—like losing your heat in the middle of the night when temperatures are below zero.
Proper design and replacement of heating systems requires thought and planning. Not all models are in stock and immediately available. It is better—and most times less expensive—to schedule equipment installations in the off season when we have the luxury of time and warm weather.
Remember, you can trust Clyde S. Walton with all your installation needs. Our professional service technicians are trained in all areas of heating and air conditioning. |
