Do we need a Carbon Monoxide detector in our home?

Posted on May 18, 2010 | by Eric Kjelshus Energy Heating and Cooling | Leave a Comment

Carbon Monoxide or CO is very dangerous. It can’t be seen or smelled and without a carbon monoxide detector.

Eric Kjelshus Energy Heating and Cooling installs and services the National Safety Institute’s Low Level Carbon Monoxide Monitor to help our customers combat the silent killer – CO.

Consider these facts about Carbon Monoxide:

Carbon Monoxide (CO) is the number one cause of accidental poisoning deaths in the United States, according to the Consumer Products Safety Commission. It’s estimated approximately 500 deaths occur each year from accidental CO poisoning. Carbon Monoxide also results in approximately 10,000 illnesses each year, for which people are treated in hospital emergency rooms, a number which is underestimated.
Carbon Monoxide is totally undetectable by human senses; it is an odorless, colorless and tasteless poison and is so deadly that it has earned the name, “The Silent Killer.” Carbon Monoxide is highly toxic and can act on the body quickly in high concentrations, or slowly over long periods of time.

Household appliances can be a deadly source of CO poison

Even with regular maintenance and checkups, any appliance can malfunction at any time, silently emitting poisonous CO into your air with no warning. CO is a by-product of incomplete combustion of fuels like natural gas, liquid propane, coal, oil and wood.

This means a defective furnace, a blocked chimney, faulty gas appliances like a water heater or range, clogged venting or a car idling in the garage can all present a serious danger to your family. Unless, of course, you help guard your family against this threat by having at least one dependable CO detector in your home.

No appliance is designed to last forever. The potential for exposure to CO is a real one, and your family could be poisoned without even knowing it. Installing a CO detector is one important way to alert your family to this potential danger.

Symptoms of CO Poisoning

At low level concentrations, CO can go undetected and contribute to nagging illnesses. Symptoms such as headaches and fatigue are common to illnesses such as the flu or the common cold. Things like “memory loss” and “facial ticks” are also symptoms of “Low Level” CO poisoning.

Home Centers and Hardware stores sell CO Alarms but they may be inadequate

Consumers Reports states the biggest problem with CO Alarms is “False Alarms” and “No Alarm” situations. Imagine your house is filling up with toxic CO levels an your CO Alarm is hanging silently on the wall. Yikes! That’s why we strongly suggest you buy what the pro’s sell. A CO Monitor with both low and high level alarms.

Saving a few bucks can have draw-backs. But here are the facts… most alarms sold in a Home Center or Hardware Store only provide “High Level Protection.” Good but not good enough for you family’s complete protection.

In addition, most CO alarms sold in Home Centers and Hardware stores have a 2 year life-span (as often stated in the fine print). Compare that to the industry standard “electrochemical sensor” with a full 5 years life span…guaranteed.

That is why Eric Kjelshus Energy Heating and Cooling installs and services the National Safety Institute’s Low Level Carbon Monoxide Monitor.

What to do if you’re CO Monitor goes off

Get out of the house! Don’t open windows…. Don’t check your alarm…. Call your service provider from a neighbors home to perform a CO Investigation. Skilled technicians are great but what you want in an alarm situation is a Technician trained in “Combustion Efficiency” and “Carbon Monoxide Detection.”

You may also call the Fire Department or Utility Company if your alarm goes off. The fire department will respond to a CO alarm. It’s their job as first responders to check your blood for dangerous levels of CO. They will also evacuate you from the premises if a serious CO condition exists. However, fixing the problem is not their job, you must call a heating contractor.

Utility companies also by law have to respond to a CO call but it’s not free. When they arrive their technician will determine if the conditions in the house are safe or not…however, many times they fail to determine the exact cause and shut off your gas supply if a dangerous condition exists. Even if they stumble into the source of CO they still will shut down the suspected appliance. They will generally advise you to call a contractor.

What Are We Breathing?

Posted on May 17, 2010 | by Eric Kjelshus Energy Heating and Cooling | Leave a Comment

Air pollution is a common contributor to lung disease. Diseases such as asthma, respiratory tract infections and lung cancer claim over a quarter of a million lives every year. While some forms of air pollution are uncontrollable. The indoor air quality of your home or office is something that can be controlled. Poor indoor air quality can cause serious chronic respiratory diseases in some cases, however, more common problems are often chronic sinusitis, headaches, dry eyes, nasal congestion, nausea and fatigue. In addition, those already with respiratory problems are placed at even greater risk. There are a number of different sources of indoor air pollution, some more harmful than others, but all can be controlled to a certain extent.

BIOLOGICAL POLLUTANTS

Biological contributors to poor air quality include toxic mold, bacteria, mildew, viruses, animal dander, dust mites and pollen. These pollutants can originate from a variety of sources. Pollen produced by plants; viruses and bacteria can be carried and transmitted by people, animals, soil and plant debris; and any household pets are a source of dander. Any sort of ventilation system, whether it be heating or cooling, can be a breeding ground for biological pollutants if air ducts and air filters are not cleaned properly; effectively spreading them through your home or office.

RADON

Some sources of poor indoor air quality may remain hidden until tested. Radon is a naturally occurring radioactive gas most commonly produced from uranium decay in soil and rock. Radon is colorless and odorless gas that can leak into homes through dirt floors, exposed rock, cracks in the foundation floor and walls, drains, wells and any other opening to subterranean soil. Radon is estimated to be the second leading cause of lung cancer and approximately 1 out of 15 homes in the United States have radon levels above the EPA’s recommended action level.

ENVIRONMENTAL TOBACCO SMOKE (ETS)

Environmental tobacco smoke, also known as “second hand smoke” or “passive smoking”, is a combination of smoke directly from the end of a cigarette and the smoke exhaled by the smoker. ETS is known to contain over 4,000 chemicals, 200 of which are poisonous and approximately 40 which are carcinogenic. ETS is one of the few causes of poor indoor air quality that is completely preventable.

FORMALDEHYDE

Formaldehyde is a chemical used widely in the building construction industry. In homes and offices, the most common source is formaldehyde-based adhesives used in carpets, upholstery, particleboard, plywood, and fiberboard. It is a colorless yet pungent-smelling gas that can cause eye, nose and throat irritation as well as headaches, dizziness and nausea.

ASBESTOS

Asbestos is a mineral fiber commonly used in older building construction materials. It was used mainly for its durability as an insulator and fire-retardant. Asbestos is most commonly found in older homes in furnace insulating materials, shingles, pipe insulation, and floor/ceiling tiles. Asbestos is dangerous when microscopic particles become suspended in air. Asbestos particles become airborne when asbestos-containing materials are disturbed through remodeling activities such as sanding and cutting. Improperly removing such materials also leads to increased airborne concentrations. High concentrations of airborne asbestos particles can cause serious health risks such as lung cancer, mesothelioma, and asbestosis. Symptoms of these diseases do not become apparent until years after initial exposure.

CARBON MONOXIDE/NITROGEN DIOXIDE

Home appliances and heating systems that use natural gas, fuel or wood can all contribute to poor indoor air quality. Any type of combustion appliance that is misused, improperly installed and maintained, or inadequately ventilated can cause high levels of exhaust byproducts including Carbon Monoxide (CO) and Nitrogen Dioxide (NO2). Carbon Monoxide is a colorless and odorless gas that interferes with the body’s oxygen delivery systems. High concentrations can cause unconsciousness and even death, while low concentrations lead to headaches, nausea, disorientation and fatigue. Nitrogen Dioxide is a colorless and odorless gas that can cause irritation to mucus membranes such as eyes, nose and throat. High exposure can lead to shortness of breath and prolonged exposure can lead to damaged respiratory tissue as well as chronic bronchitis.

HOUSEHOLD CHEMICAL PRODUCTS

There are many household products that can lead to poor indoor air quality. Cleaning products, personal care products, pesticides, paints and solvents all contain chemicals that can lead to allergic reactions and irritations if not used properly.

Mold- Construction & Remodeling

Posted on May 17, 2010 | by Eric Kjelshus Energy Heating and Cooling | Leave a Comment

If you are building a new home, or just doing some remodeling, you may have concerns about mold and its possible health effects. Besides expensive damage to your property, mold growth can contribute to poor indoor air quality in your home, potentially resulting in dangerous health problems.

Mold concerns have been getting a lot of attention in the news. Numerous legal cases have arisen in which millions of dollars have been awarded because of mold infestation in new construction. But is the mold problem really a new one?

Mold has been a problem for builders since pre-biblical times. Over the millennium, however, the more-successful builders employed a few simple techniques that dramatically reduced the risk of mold in their buildings. As a homeowner, you want to make sure your contractor is building a safe, healthy home for your family. Here are some helpful tips you can use to make sure your new home or addition is mold free:

KEEP IT DRY

Molds are microscopic organisms that are present virtually everywhere in our environment. Molds break down dead organic materials, such as wood and leaves, and recycle nutrients back into the environment. All that is necessary for mold growth to start on these materials is moisture.

Generally, within 48 hours after getting wet, invisible mold growth has started on wet woods and paper-backed products such as Sheetrock. After about four days, mold growth on surfaces is visible in the form of discoloration, frequently green, gray, brown or black, but also white and other colors.

Because molds digest organic material, they gradually destroy whatever they grow on. Molds also release countless tiny, lightweight spores, which travel through the air. These mold spores provoke allergic reactions in many people, and contribute to asthma attacks. They can also produce dangerous mycotoxins, poisonous substances linked to a variety of serious health problems, some even fatal.

In finished construction, roof and window leaks, plumbing defects, drainage and grading problems, and other sources of water infiltration can trigger the chain of events that ultimately leads to active mold growth. But in new construction, there are some simple steps to take to cut down the chance of mold infestation.

PREVENTING MOLD

Simply put, the best advice is this: Do not build with wet materials. This may present a challenge in certain climates of the United States, especially during rainy times of year, but there are still several steps a prudent contractor can take to prevent or minimize mold growth.

As simple as the advice may be, you’d be surprised how often it goes unheeded. Poor weather conditions, unrealistic construction schedules, and even ill-advised drives for “efficiency” in construction causes many contractors to ignore some of the most basic mold-prevention tips. Sit down with your contractor before building begins, and express your concerns about mold in your home.

Mold spores are always present in both indoor and outdoor air, and they can flourish in any ambient temperature from 40 F to 100 F (4 C to 38 C). But you can have some control over the moisture mold needs, and you can also have some control over the use of organic materials in construction.

Because some moisture is inevitable, either during installation or from condensation, use components that will retain as little moisture as possible. Moisture-resistant materials will cut down on retained moisture. Specify materials that have no organic content as part of your overall mold-resistance strategy. For example, paper facings could support the growth of mold. Some of the new “paperless” gypsum wallboard might be a good alternative. Materials that don’t have organic components resist mold.

Of course the use of some organic building material—such as lumber, for example—is unavoidable. Here are some tips to follow to prevent mold growth in these materials:

1. Keep stocks of lumber, plywood, oriented-strand board (OSB), Sheetrock, and other porous materials in a dry, covered storage area. If the stockpiles are out in the open, and it looks like it might rain, cover the materials with a good tarp, anchored down so that the wind does not blow it off. When the materials are needed, remove them from beneath the cover without allowing the remainder to get wet or damp.
2. Inspect carefully for water damage.Before installing the materials, inspect carefully for water damage, staining, warping, or initial signs of mold growth. Such signs might be visible patches of mold, or simply the musty odor we associate with mold or mildew. Discard any such materials immediately.
3. Install a roof or cover the new construction as soon as practical.If the rain is falling, the interior spaces of the building are getting wet. Moisture is one of the key things mold spores need to grow.
4. Thoroughly dry out the wet materials. If the materials are merely wet, all hope is not lost. Bring in portable heaters and dehumidifiers to thoroughly dry out the wet materials before covering them up or sealing up the building. A contractor can employ a simple moisture meter to make sure the previously wet materials are sufficiently dry to allow construction to proceed.
5. Existing mold growth should be cleaned up completely before anything new is added.If, despite these precautions, mold starts to grow on installed building materials, do not attempt to “cover it up” by installing dry lumber or Sheetrock over it. Mold spreads very rapidly in a moist environment, and the wet materials will serve as a moisture source that will rapidly transfer damage to the previously clean, dry materials. Existing mold growth should be cleaned up completely before anything new is added.
6. Do not try to simply wipe off mold or paint over it. The underlying moisture that is supporting the mold growth will not go away, and the mold will likely reoccur, even after construction is complete. In addition, the materials might already be structurally or functionally damaged, and paint will not cover that up for long. Most mold-infested porous materials must be removed and discarded.

MAINTAINING A MOLD-FREE ENVIRONMENT

By following these common-sense practices, your contractor can have you well on the way towards living in a healthy, mold-free home. After the construction is done, make sure to keep your home free from indoor air quality hazards. Refer to our article Twelve Steps to Improving Indoor Air Quality for more helpful tips.

Your home comfort system is in the background, running all day long, on and off, for most of the year. It keeps you comfortable, catches your dust, and zaps those nasty cold viruses. It needs to be properly cleaned and maintained.

12 Steps to Improving Your Indoor Air Quality

Posted on May 17, 2010 | by Eric Kjelshus Energy Heating and Cooling | Leave a Comment

1. Test your Indoor Air Quality

If your family is sensitive to mold, you may conduct tests for mold only; or you can do a comprehensive test with a complete breakdown of your air makeup, helping you decide where problem areas lie. These tests are relatively inexpensive and readily available, and are a great starting point for improving the air quality in your home, giving you an idea of which areas to tackle first. After employing these 12 strategies, test the indoor air quality again to confirm whether or not you have removed dangerous elements from your breathing air.

2. Make your home smoke-free

Environmental Tobacco Smoke (ETS), often known as “second hand smoke,” is very harmful and can lead to serious health problems such as chronic sinusitis and lung cancer in adults and lower respiratory tract infections in children. Taking smoking outside reduces concentrations of toxic chemicals and carcinogens found in ETS and is an important factor in improving indoor air quality in the home or office.

3. Improving ventilation improves indoor air quality

Ventilation is easily improved by leaving doors between rooms open as well as opening windows whenever possible. Exhaust fans should be used in bathrooms, kitchens, and laundry rooms to vent moisture and chemicals directed outdoors. Quiet, energy-efficient fans can be used for these applications.

4. Control household humidity levels

Keeping low humidity levels is important in controlling the growth of toxic mold and other biological contaminants. This can be done by eliminating water leaks and sources of standing water. Also use your air conditioner, and install dehumidifiers in problem areas such as basements. Keep the dehumidifier clean and free from mold, as they can become sources of pollution if contaminated. If you live in a high humidity part of the country, home mold testing is recommended to ensure clean air.

5. Have your HVAC system cleaned

Much more important than cleaning your duct work is having your HVAC system cleaned. Your A/C drip pan could be holding water and growing mold which will then be blown directly into your air ducts and out through the vents. The blowers for your HVAC may not have been cleaned in years, and could have built up dirt and dust and could also be harboring dust mites and toxic molds. Lastly, the condenser coils may have rust and corrosion buildup, which is not only harmful to air quality, but also decreases your HVAC system’s efficiency, increasing energy costs. A thorough furnace and A/C system cleaning varies greatly in price from company to company, but this can improve your HVAC system’s cooling and heating efficiency and save you money in the long run. Supervise the work to make sure all critical components of the HVAC system are cleaned — once they are placed back in the system, they are out of sight.

6. Prevent Carbon Monoxide poisoning

Any fuel-burning household appliance (gas stoves, hot water heaters, clothes dryers, etc.) can potentially release harmful chemicals as by-products of combustion. All such appliances should be inspected by a qualified technician once a year. You should also monitor the indoor air quality of your home by installing Carbon Monoxide detectors, especially near bedrooms.

7. Clean and Vacuum Regularly

Airborne dust particles, microscopic insect droppings, and mold spores cause allergic reactions and asthma outbreaks. Cleaning regularly can help control indoor air quality. Vacuum rugs and carpets at least once a week. Consider a vacuum equipped with an allergen reducer or HEPA filter, which prevents reintroducing allergens and fine particles back into the air. Wipe down or dust any hard surfaces regularly, and clean up mold near sinks, water pipes, or bathtubs immediately to prevent releasing allergenic or toxic spores into the air.

8. Control Dust Mites

To combat the growth of dust mites, a common cause of indoor allergy symptoms, bedding should always be washed in hot water (at least 130° F). You might consider using allergen-free cases on your mattresses and pillows. Your children’s blankets and stuffed toys can harbor dust mites as well; wash them regularly in hot water to keep your children safe from allergies and asthma triggers.

9. Put a High Efficiency Particulate Air (HEPA) filter in your air handling system

Using a HEPA Filter with help keep particles out of the air and off of the ductwork of your heating and cooling systems. Filters should be replaced with regularity, every 1-2 months depending on how much the system is running. Proper use and maintenance will help improve indoor air quality and increase time between necessary Air Duct Cleanings.

10. Exhaust Gas Appliances

Make sure gas stoves are fitted with a hood fan that exhausts directly outside. Using a hood fan and/or an open window while cooking will help improve indoor air quality, and prevent Carbon Monoxide contamination.

11. Be aware of toxic chemicals found in household cleaning products and pesticides

Household cleaning products & pesticides should be used only according to manufacturers’ directions. Keep your house well ventilated while using. In order to help preserve your home’s indoor air quality, store harmful chemicals and volatile compounds (paints, solvents, cleaners and pesticides) away from occupied spaces and air ventilation intakes. If you have aggravated sensitivity to certain chemicals, consider a home air cleaner with gas-phase filtration to keep chemical concentrations from reaching irritating levels.

12. Purchase a home air purifier

Running an air purifier in your home will help keep indoor pollutants at low levels. Used in conjunction with the HEPA filter you’ve added to your heating and cooling system (Step 9), a home air cleaner using HEPA filter technology, ionic air purification, activated carbon, or a hybrid of these technologies can keep the air in your home clean and healthy.
