Desert Dust, Asthma, Fall Allergies and Your Air Conditioner

This entry was posted in Indoor Air Quality (IAQ) on by .


As the Labor Day weekend approaches, Arizona school children have been attending classes for almost a month. Along with returning to school, comes inevitable sick days. Did you know, one of the leading causes of absenteeism due to illness is asthma? On average, almost ten percent of all school children experience asthma or some form of respiratory distress during their formative years. However, children are not the only ones affected by respiratory conditions.

Arizona is home to legions of retirees, many of whom escaped to Phoenix for warmer winters and the desert climate. Unfortunately, due to dust, pollution and plenty of pollen, the air quality in Phoenix is not the best. What does that have to do with your air conditioner? Plenty! Your air conditioner filters the air you breath. Indoor air quality is crucial. Given the fact that most people spend more than 90 percent of their time indoors, properly filtered air is vital for the care and comfort of your family. Homeowners are generally on alert for allergens in springtime, but autumn presents its own set of challenges.

Autumn Ragweed and Other Allergens

The University of Arizona Health Science Allergy Advisor states that pollen and particulates from Bermuda grass, ragweed, Russian thistle, pigweed and desert broom all are of concern in the fall. These tiny particulates can irritate respiratory passages and cause problems for those who suffer from asthma. Replacing your air conditioning filters on a monthly basis is advised, especially if you have someone with a respiratory condition living in your household.

Is Phoenix the Dustiest City in America?

There’s no doubt, Phoenix is the hottest city in America. It might also be the dustiest. If you’ve been outside during a dust storm or observed monsoon coverage on TV, you’ve seen the awe-inspiring dust clouds that extend for miles across the Phoenix metroplex and hundreds of feet into the air. Tons of wind whipped desert dust flies through the air, and some of that dust makes its way into your home. As your air conditioning filter fills up with dirt and dust, the quality of your indoor air goes down. If you’ve noticed your child wheezing or coughing more than usual, it might be time for a service checkup on your AC unit.

The Air We Breathe

Though most of us are guilty of taking oxygen for granted, the air we breathe is the most important factor to a healthy life. The Survival Rule of Threes states; you can go three weeks without food, three days without water but only three minutes without air. If you or a loved one has experienced shortness of breath due to asthma or a respiratory disorder, you know how precious air can be. Most air conditioners do a great job of cooling the indoor environment throughout the scorching Arizona summer and blazing temperatures in fall. However, regular AC service calls are essential to maintaining a high-quality, dust and particulate-free indoor environment.

The Mighty Ducts – How Dirty Ducts Can Affect Your Indoor Air Quality

This entry was posted in Indoor Air Quality (IAQ) on by .

An important yet invisible part of your HVAC system plays a critical role in distributing clean, cooled air to every room in your house. Your mighty ducts wind their way unseen through the walls, floors and ceilings of your domain. Most people never give them the slightest consideration. However, here’s an inconvenient truth. Dirty air ducts can negatively impact the indoor air quality (IAQ) of your home. As homeowners strive to create better, healthier environments for themselves and their children, IAQ has grown in importance. People spend over 90 percent of their lives indoors, and air ducts deliver the air they breathe.

Dust to Dust – What Is It and Where Does It Come From?

Did you ever walk into a sunlit room or turn your head at just the right moment in time to notice a shaft of golden sunlight illuminating all the particles of dust hanging in mid-air. You think to yourself, “Geez, I keep this place clean – what is all that?” Dust is comprised of many thousands of particles. A smorgasbord of potential irritants including soil dragged in from outdoors (in Arizona, desert dirt is literally blown in during monsoons and dust storms) pollen, ragweed, mold, cigarette smoke, particulate smog floating in air from automobile and gas engine exhaust, tiny threads and fibers from rugs and furniture upholstery, indoor pollutants from household activities like cooking and using cleaning products, pet dander and let’s not forget, a fair amount of your dead, exfoliated skin! A typical household can generate up to 40 pounds of dust per year.

Having Your Ducts in a Row

All that dust in your home is circulated through your air conditioning system and carried from room to room by your air ducts. In a perfect world, air filters would be changed routinely. Dust and allergens would be, for the most part, eliminated. And, your air ducts would remain clean, aligned and relatively airtight. Unfortunately, as all homeowners know, stuff happens. Over the course of years, dust and dirt will build up inside air ducts. Sometimes filters don’t get replaced in a timely manner. Air ducts can get damaged due to remodeling, or a house settling. Leaks from the roof can introduce water into your air duct system. We’ve even heard of less-than-knowledgeable contractors moving ducts in order to deal with a problem in the ceiling rafters or behind a wall and simply forgetting to reconnect the duct and put it back in place correctly.

At the end of the day (or thousands of days – some systems haven’t been checked in years) your duct system is probably the most forgotten and ignored place in your home, even though it delivers precious air throughout the house.

Should I Get Rid of My Exhaust Fans?

This entry was posted in Indoor Air Quality (IAQ) on by .

Exhaust fans may seem like a rather outdated bit of technology, given the fact that so many high-tech gadgets are appearing all the time for use in the home, but in truth these simple devices still serve a very useful purpose in the home, and especially in bathrooms. Most new homes come with the exhaust fans already installed, but surprisingly they are not always as effective as they could be. Here are some of the common functions that exhaust fans are intended to perform, and if you feel that your fans are not living up to these standard functions, you should probably shop around for some more effective exhaust fans, because they really can be a benefit to all concerned.

Moisture removal

The most obvious purpose of a bathroom exhaust fan is of course to remove moisture from the air, and this can be a major function because all the occupants of your home are showering and taking baths daily, which can lead to the retention of high levels of moisture in the room. If that moisture is allowed to collect and stay in place, it can easily lead to the growth of mold and mildew, which would then become a health hazard for household residents.
Management of odors

Another primary function of bathroom exhaust fans is the elimination of unappealing odors in the room. A well-maintained bathroom exhaust fan extracts these odors, and conducts them out of the room so that subsequent users are not offended by unpleasant air quality. In a household of numerous occupants, this can be a fairly significant issue, especially if everyone has to use the same bathroom.

Fume control

Ironically, actions taken to maintain cleanliness and health in the bathroom can actually lead to problems. For instance, many cleaning agents are comprised of fairly aggressive chemicals, and these can become a health problem when inhaled, particularly for people who already have respiratory issues. It can also significantly impact young children and elderly residents of the home. An exhaust fan can be a big help with eliminating chemical odors that might otherwise lead to health issues in the home

It’s there, but is it used?

From the above, it’s easy to see that bathroom exhaust fans provide a really useful service to household residents, and should be used appropriately to overcome the common issues they are intended to. In many cases however, people are reluctant to use bathroom exhaust fans because they’re loud or noisy, and they don’t want to be disturbed by them.

If this is the case in your home, you should have your bathroom exhaust fans checked by a reputable service technician, because there’s a good chance it simply wasn’t installed correctly, and is not functioning up to manufacturer specifications. Homeowners in the area of Scottsdale, Peoria, Sun City, Surprise, or Glendale are fortunate, in that you have access to the expert HVAC professionals at Cool Blew Inc.

Keeping You and Your Four-legged Friends Cozy

This entry was posted in Indoor Air Quality (IAQ) on by .

If you live anywhere around the region which includes Peoria, Scottsdale, Phoenix, Sun City, or Surprise, you’ll know that keeping your air condition in great running shape is very important for your comfort and for the quality of the air you breathe indoors. But have you ever thought about how it affects your cat or dog? Your pet is breathing the same air that you are, and it is affected in much the same way by the indoor air quality of your home. When your air conditioner or your furnace is not performing at peak efficiency, your four-legged friends are suffering just like you are.

Poor indoor air quality

When air is not being conditioned properly inside your home, it can lead to some serious respiratory issues, or even some cardiovascular problems, both of which can affect humans and pets. Air quality can easily be degraded by cooking fumes, mildew, cleaning products, and cigarette smoke, all of which can be harmful to your pets and yourself. For both your own well-being and for the safety of your feline/canine friends, healthy air quality needs to be maintained.

Simple enhancements

There are some very simple things you can do to improve air quality in the home, the first of which should be regularly cleaning your reusable filters, or discarding dirty filters which are not reusable. When you have pets in your home, filters are almost certain to attract animal hair, along with all the other pollutants it extracts, such as pollen, dirt, mold, and bacteria. No smoking should be allowed indoors at all, because smoke-laden air will be breathed in by everyone in the home, including pets.

If there are any cracks or gaps in the structure of your home, they could allow external contaminants inside, so these should be filled in somehow to prevent penetration by sources of contamination. It would also be a good idea to regularly groom your pets, because if they’ve been outside at all, they can easily bring in pollutants.

Air quality solutions

Beyond the simpler enhancements that you can do without incurring expense, you can also invest in the improvement of air quality by installing air purifiers, humidifiers, ventilation systems, and even ultraviolet lamps. All of these can enhance air quality in their own way, and should be considered as potential solutions depending on the specific shortcoming of your air quality. Having your ductwork cleaned at least once a year will also remove a great deal of debris and pollutants from your home’s air circulation network, and it will also improve air flow in general.

Call the professionals

To be sure that the air quality of your home is healthy enough for you and your pets, call the experts at Cool Blew Inc. and schedule an evaluation of your air quality. If any steps need to be taken to improve it, your HVAC specialists are sufficiently knowledgeable and experienced to make just the right recommendations for your home.

Indoor Air Quality Attracts Quality Tenants

This entry was posted in Indoor Air Quality (IAQ) on by .

When you’re trying to attract quality tenants to your rental property or apartment complex, there are a great many things you can do to make it appealing to potential tenants. For instance, you can make use of all available channels for advertising, so that you can reach a wide audience, after which you would screen for the most suitable clients.

One component of this advertising should be to make the exterior landscape surrounding the rental unit as appealing as possible, because anyone casually driving by would then acquire a great first impression of the property. When you’re conducting tours through rental units, the first thing prospective tenants will see is the surrounding landscape, and how well it’s maintained.

You might be surprised to learn that another very effective way of attracting quality tenants is by ensuring that breathable air in the living spaces of rental units is a benefit to them, made possible by your conscientious upkeep of HVAC systems within the units. In the region which includes Glendale, Peoria, Scottsdale, Surprise, Phoenix, and Sun City, you can ensure that the HVAC systems in your rental units are operating at peak efficiency by having regular maintenance performed by the professionals at Cool Blew Inc.

Keeping up repairs and maintenance

Good tenants quickly become disillusioned with management or landlords when equipment and appliances provided in rental units are not kept up to snuff, thereby diminishing the comfort of residents, and instead becoming a source of irritation. This is particularly true of HVAC units, which have a direct bearing on the comfort of everyone inside, as it relates to indoor air quality.

In order to be really comfortable, residents must be provided with well-conditioned air appropriate to the season, with indoor air quality which is constantly filtered and kept fresh, and free of contaminants. This is of particular concern to people who have respiratory issues to begin with, but in truth it affects everyone, regardless of their health status.

Emphasize benefits

Many landlords and property managers make the mistake of overlooking benefits while promoting the features which a rental unit may have, for instance a ‘new refrigerator’ or a ‘third-floor location’. By themselves, these announcements don’t mean much, and they are not as appealing as they might be to a prospective tenant.

However, by listing the benefits instead of the features, they can be made much more attractive. In the two cases mentioned above, they could be modified to say ‘highly efficient, low energy cost refrigeration unit’, and ‘outstanding upper-level apartment with a great view of the surrounding area’. In the same way, announcing to tenants that a furnace or air conditioner is new doesn’t evoke much in the way of appeal. Far better would be to say a ‘modern, energy-efficient air-conditioner capable of maintaining fresh, contaminant-free indoor air, promoting good health for all residents’.

Tips For Preventing Carbon Monoxide Poisoning In Your Home

Tips To Prevent Carbon Monoxide In Your Home-CoolBlewMany homes use hydrocarbons in cooking, powering furnaces, central heating and space heaters among other things. Burning of these fuels produces carbon monoxide, which is very dangerous if it leaks and finds its way into the home. It is hard to notice the presence of this gas because of its odorless and colorless characteristics.

Benefits Of Better Indoor Air Quality For Businesses-CoolBlewThe word “pollution” tends to conjure images of city smog, exhaust from vehicles, and other outdoor hazards. People forget that the air they breathe indoors is not always the cleanest or safest either. In fact, indoor air pollution may be up to five times worse than what we encounter outside.

The common culprits in a business environment include dust, paint, mold, and other allergens. The presence of volatile organic compounds or VOCs like phthalates and formaldehyde make things even worse. Businesses should implement measures to reduce VOCs and ensure that the HVAC system is able to filter contaminants. Giving proper attention to indoor air quality (IAQ) results in the following benefits: Continue reading
