Where does indoor air pollution come from?




Modern man spends a great deal of time indoors – some 90% of our lives in the “shelter” of homes and buildings. Unfortunately, all this time indoors can come at a cost to our health. Tighter building designs geared toward energy and cost savings are trapping pollutants inside the dwellings where we seek respite.
Rather than
clean indoor air, we are instead being assaulted by pollution levels two to five times higher than the air outdoors.
Where are all those pollutants coming from?
  • Mold and mildew
    High humidity and dampness resulting from condensation, poor ventilation, plumbing and other leaks can aid in the proliferation of mildew and mold, triggering allergy and asthma symptoms, eye, skin, nose, throat, and lung irritation, as well as upper and lower respiratory issues in those exposed.
  • Biological contaminants
    Biological contaminants in your home include not only mold, mildew, bacteria and viruses, but pollen, dust mites, cockroach feces, and more. Contaminants are carried in via your person or on your pets, and are distributed throughout your home – even through your HVAC ducts. These contaminants are capable of aggravating allergies and asthma and/or causing disease, but can be easily controlled with the use of
    high quality filters and UV germicidal lamps.
  • Smoke
    Smoke from both cigarettes and combustion burning create gases and particulates that carry a host of chemicals which can result in eye, nose, and throat irritation, respiratory irritation and infections, emphysema, lung cancer, and more.
  • Asbestos
    A natural mineral fiber used in various building components in most homes over 20 years old, including insulation, flooring materials, and more, asbestos exposure can ultimately result in abdominal, chest, and lung cancers and asbestosis.
  • Radon
    Colorless, tasteless, and odorless, radon is created from the naturally occurring breakdown of radioactive materials in earth and rock. Symptoms are not immediately apparent, however radon is linked to an estimated 20,000 lung-cancer deaths annually.
  • Carbon monoxide (CO)
    Colorless and odorless, CO gas is produced during the incomplete combustion of all carbon-based fuels, including commonly used wood, charcoal, gas, diesel, kerosene, propane, and other natural gases. Often mistaken for the flu, exposure causes headache, drowsiness, dizziness, impairment of respiration, vision, and brain function, and ultimately death. If you fear CO may be an issue in your home, consult an
    indoor air quality service professional right away.
  • Formaldehyde and other VOCs
    Off-gassing from pressed wood products, foam insulation, glues and adhesives, carpet and upholstery, household cleaning and deodorizing products, and more can release pungent gases into the air capable of causing allergic reactions, headaches, nausea, dizziness/confusion, eye, nose and throat irritation, coughing. Multitudinous VOCs are linked to brain, liver, and kidney damage, as well as various cancers.
  • Lead
    Lead-based paint, pipes, and fixtures in older homes can contribute to airborne dust particles, causing significant health effects including cognitive and developmental issues in children, brain, nervous system, and kidney damage, anemia, hearing loss, and even death.
Ventilation plays a starring role in indoor air quality
To provide efficient energy use, particularly with regard to your home’s heating and cooling equipment, homes are specifically designed to minimize the amount of air that can leak into and out of them. This can result in the need for enhanced ventilation and specialty air filters in your
HVAC systems to preserve the air quality in your home. Options include:
  • Site-specific exhaust fans, such as in the kitchen and bath.
  • Whole house air purifiers with UV lamps.
  • Mechanical ventilation, such as exhaust or supply ventilation systems and heat recovery ventilators.

Things to Check Before Calling for Air Conditioning Services in Delaware County, PA






Air conditioner on the fritz? Hold up - don't call your air conditioning contractor yet! If your air conditioner isn’t operating properly, it may only be a minor issue. Try these simple solutions before scheduling your air conditioning system repair:
  1. Is it on?
    Does your system have power to it? Make sure the main power switch in the “On” position for proper operation. Sounds silly – because it worked yesterday – but kids, animals, weather, and accidents happen. Avoid the frustration of a repair bill over a flipped switch. Check these items first.
  2. Did you blow a fuse?
    We don’t mean your aggravation at the current state of your system!
    Air conditioning units pull quite a bit of power. Check your circuit breaker panel and ensure the necessary breakers are in place, turned on, and functioning properly. Watch out for tricky breakers – those that have only tripped halfway, which may appear at a quick glance to be alright. They will need to be fully turned off and returned to the on position.
  3. What is your thermostat set on?
    Sometimes family members – particularly younger ones – can unknowingly sabotage your system. Check to see first that your system is in cooling mode. Then check to see that it is set at the correct temperature to cause the system to come on.
  4. Do you need to close the door?
    Not your front door, the blower door on your air handler. It must be securely closed for proper operation.
  5. Experiencing a clog?
    Check the drain line next to your outdoor unit. Lines that are buried or clogged with algae (which you may not be able to see) can cause your home to get sticky due to the improper operation of the system. A condensate overflow tray that needs to be emptied can also cause problems.
  6. How cruddy is your filter?
    An extremely dirty air filter can block air supply to your system and prevent proper function. If your filter is gross, try swapping it out (if it is disposable) or cleaning it (if it is a permanent filter) before calling the repair man.
  7. Is you system not shutting off?
    You may need to adjust the temperature. If you raise the thermostat 5-10 degrees and your your system can only manage temperatures about 20 degrees cooler than the outdoor air. If its 100 outside, be thankful for 78-80 degrees.
  8. Do you have an owner’s manual?
    If you’ve tried the above solutions, or if you have a specialty system like a
    geo thermal heating and cooling system, consult your owner’s manual. It may offer additional troubleshooting suggestions specific to your system.
