Do I Need an Indoor Air Quality Testing?

Indoor pollution sources that release gases or particles into the air are the primary cause of IAQ problems in homes. Inadequate ventilation can increase indoor pollutant levels by not bringing in enough outdoor air to dilute emissions from indoor sources, and by not carrying indoor air pollutants out of the home. High temperature and humidity levels can also increase concentrations of some pollutants. Primary factors that affect IAQ are carbon monoxide, carbon dioxide, volatile organic compounds, particulates, temperature and humidity.​

Carbon Monoxide (CO)

(CO) is a colorless, odorless gas that interferes with the delivery of oxygen through the body. The most common symptoms of CO poisoning are headache, dizziness, weakness, nausea. Potential sources are defective central heating furnaces, tobacco smoke, fireplaces and other appliances that may use fuel in the home. If you breathe in a lot of CO it can make you pass out or kill you. CO can build up indoors and poison people and animals who breathe it.

Carbon dioxide (CO2)

(CO2) is exhaled by humans and pets as a natural part of the metabolic process. Rapid rise in carbon dioxide levels indicate inadequate fresh air being brought into the building, and often is accompanied by a feeling of “stuffiness” and some mild symptoms, such as tiredness. ASHRAE recommends that indoor CO2 levels not exceed 700 ppm above outdoor ambient levels. The solution for high CO2 levels in the air is adding ventilation.


Particulates can induce eye, nose, and throat irritation; respiratory infections, bronchitis and even lung cancer. Particulates include asthma triggers and mold. Ultrafines can emanate from a variety of equipment and processes, such as dry toner copiers and printers, water heaters, furnaces and boilers.


Astma triggers include mold, dust mites, secondhand smoke, and pet dander, as well as other pollutants in the air. Asthma triggers cause symptoms including coughing, chest tightness, wheezing, and breathing problems. Asthma attacks can be life threatening. However, asthma can be controlled by reducing asthma triggers. Indoor air pollution can make life miserable for people dealing with asthma. Make sure your family is breathing clean air.T


Mold is living thing that produces spores. Mold growth is one of the most common indoor air quality problems. Mold produces spores that float in the air, land on damp surfaces, and grow. Inhaling or touching mold can cause hay fever-type symptoms such as sneezing, runny nose, red eyes, and skin rashes. Mold can also trigger asthma attacks. Indoor humidity can increase the likelihood of mold. Indoor humidity should be kept between 30 and 50 percent.

Efficient, quality service. Very knowledgeable about the equipment and offer affordable "no-need to hagle" pricing. Would definitely recommend them.
GSHA Services converted an old boiler system to a forced air system. Since the house was built in 1922 it had its challenges. Peter's crew did an incredible job. They were very neat and clean the whole time. We are extremely happy with the job they did and would highly recommend them to everyone.
