Reduce Your Risk of Airborne Viruses with the Air Scrubber Plus

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

It’s definitely a time of uncertainty with the ongoing spread of COVID19. Of course, it’s important for all of us to be doing our part in combatting the virus while protecting the health of ourselves and our loved ones. As we slowly begin to transition away from sheltering in place, it’s natural to begin thinking about ways to mitigate risks. For many of us, this may include wearing masks in public places, avoiding large gatherings and frequent handwashing.

Because researchers are now exploring the possibility that COVID19 may spread via airborne transmission, as well as droplet transmission, there has been growing interest in technologies that purify indoor air.

At Cool Blew, we’ve been impressed with the ActivePure technology used in the Air Scrubber Plus – a system designed to eliminate indoor air quality risks by reducing pollutants, VOCs, cigarette smoke, dust, pollen, mold, bacteria and odors. While this technology has not been specifically tested yet against COVID19, it has been shown to reduce viruses, including swine flu (H1N1), avian bird flu (H5N8), hepatitis A and norovirus.

The ActivePure technology, built into the Air Scrubber Plus, was developed for use on the International Space Station and has been shown to reduce up to 99.99% of harmful contaminants throughout a home. The system is simple to use and helps ensure that air ducts, as well as furniture, countertops, bathroom surfaces and more are cleaner and safer for you and your loved ones. In fact, the technology reduces over 90% of pathogens in 30 minutes – making it 50 times more powerful than normal HVAC filtration. This is why it is relied upon in Major League Baseball facilities, hospitals, schools and by many hotel brands.

If you’re concerned about the quality of your indoor air and reducing your risks of viruses, as well as other airborne and surface contaminants, call Cool Blew today for more information. We’re your go-to source for indoor air quality during these challenging times.

Your Home’s Plumbing and Coronavirus – What You Need to Know

This entry was posted in Plumbing on by .

It seems like coronavirus (COVID-19) is impacting nearly every aspect of daily life these days, and this includes home plumbing systems.

As the pandemic started to spread throughout the United States, many individuals began stockpiling essentials like toilet paper, tissues and wipes for sanitary purposes. At the same time, we’ve all been obeying stay-at-home orders. All of this has led to a perfect storm of strain on sewer systems, as well as clogged sink lines and toilets.

To minimize your risk of having a pandemic-related plumbing problem, we wanted to share some preventive practical strategies.

Don’t Flush Wipes Down the Toilet!

There really is no such thing as a flushable wipe. Whether they’re for cleaning surfaces or cleaning yourself, they simply don’t break down like toilet paper and are a primary source of the current rise in plumbing issues. In other words, the only things you want to flush are the three Ps – pee, poo and (toilet) paper.

Avoid Pouring Grease, Fat and Oil Down Drains

With restaurant doors shuttered, many of us are spending much more time in the kitchen. That’s a great thing. But, it’s important to remember that when you’re cooking, you want to place grease in a sealed container and dispose of it in the trash. Grease and oil poured down drains can adhere to the insides of pipes that carry wastewater from homes to sewer treatment facilities. Over time, this buildup can reduce the flow of wastewater and damage your sewer line.

Manage Toilet Paper Usage

If you’re one of those homeowners who has stocked up on a year’s worth of TP, it can be tempting to overuse toilet paper during your bathroom visits. Like wipes, too much toilet paper can clog toilets and damage pipes. Remember – more doesn’t always mean better when it comes to toilet paper usage. Be thoughtful in your approach to hygiene and breathe easy that you have more than a “square to spare.”

While we, at Cool Blew, are available for all your plumbing needs, we encourage you to follow these tips to help keep your system healthy and flowing.

Optimizing Your Indoor Air Quality for Your Home Office

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

With the shift to social distancing, many of us are now working from home. While workplaces are designed for employee productivity, most home offices lack the same characteristics. Among the most important aspects of a healthy and comfortable home office space is optimized home’s air quality.

According to a study from Harvard T.H. Chan School of Public Health and SUNY, individuals who work in better air quality have higher cognitive functioning scores – compared to those working in airtight environments with poorer air quality. Most homeowners are surprised to learn that indoor air can be polluted by lead, formaldehyde, fire retardants, radon and even volatile chemicals used in common cleaners. Some of these pollutants are tracked into a home, while others appear with the addition of a new mattress, furniture, paint or carpet cleaning. Then, there’s the additional issue of dust mites, mold, pet dander and other indoor pollutants.

The key to improving indoor air quality is taking a multi-pronged approach to minimizing pollutants and optimizing humidity.


Allergens and chemicals accumulate over time, impacting air quality. One of the best front-line defenses against this is vacuuming carpets and floors which can reduce toxins and allergens. Choose a vacuum cleaner with strong suction, rotating brushes and a HEPA filter. For optimal results, vacuum two or more times each week and regularly clean the filter.


Mopping is also beneficial by picking up additional dust that the vacuum has left behind on floors. Use plain water, rather than soaps and cleaners and a microfiber mop which can capture the most dust and dirt.

Use Door Mats

Place a large floor mat at every door to catch chemicals and dirt on shoes before they are tracked through the house.

Maintain a Comfortable Humidity Level

By keeping humidity around 30 to 50 percent, you can minimize the growth of dust mites and mold while preventing air from becoming too dry. With our desert air, a humidifier may be beneficial in a home office to ensure a consistent humidity level.

Don’t Smoke

Making your home a no smoking zone is essential for good indoor air quality. Cigarette smoke contains over 4,000 chemicals and is linked to higher rates of respiratory disease, cancer, heart attacks and stroke. And in this time of a pandemic, avoiding smoke is more important than ever.

Call Cool Blew

At Cool Blew, we’re experts in indoor air quality management and recommend the Air Scrubber Plus – a new system designed to help eliminate indoor air quality risks by reducing air pollutants, VOCs, cigarette smoke, dust, pollen, mold, odor-causing bacteria and odors from pets and cooking. Call us today to learn more about this system and how it can enable you to breathe easier as you work from home.

Coronavirus and your HVAC System

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

You can’t turn on your TV without seeing news about the coronavirus outbreak in the United States. While plenty of people are stocking up at the local grocery stores on items like toilet paper, bread and water, there are some things we can all do at home to help minimize the spread of viruses while improving the overall quality of indoor air during cold and flu season.

One of the big questions surrounding coronavirus is how significant of a role airborne transmission plays in its spread. Currently, the general consensus is that it’s predominately spread through large droplet transfer – meaning droplets are too large to remain airborne for long. In other words, transmission is primarily happening through coughing and sneezing within a fairly close range of other people.

However, that doesn’t mean that your HVAC system can’t play a role in prevention. In fact, it can have a significant impact on keeping you healthy, so that your immune system is prepared if and when it is exposed to the virus. The following steps can help fight illness and improve your air quality.

Replace Air Filters

Air filters are a first line of defense against bacteria, viruses, pollen and other particulates that can circulate in your ductwork and indoor air. During cold and flu season, it’s always a good idea to replace your system’s filters at least once a month.

Schedule Regular Maintenance

Your HVAC system should ideally be cleaned and serviced twice a year to ensure it’s working optimally. Filters, belts, condenser and evaporator coils and other parts should be tested and cleaned. With good maintenance, dust, pollen and other airborne particles can be removed from your system to prevent air quality issues.

Clean Air Ducts

Like your air conditioner furnace or heat pump, your ventilation system also needs regular maintenance. Ductwork should be cleaned and serviced to remove dust, mold and microorganisms that can collect there.

Partner with HVAC Professionals

Your indoor air quality isn’t something to take casually now – or really any time of the year. Poor quality air can have a big impact on the health of both those with chronic conditions, as well as healthy individuals. A qualified HVAC contractor is the best choice for analyzing your system, ensuring its working effectively and keeping air quality at optimal levels.

How Your HVAC System Can Help You Tackle Seasonal Allergies

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

With temperatures warming up, Arizona is in bloom. While wild flowers and leafy trees are a beatiful addition to our desert landscape, they are also shedding tremendous amounts of pollen. For allergies sufferers, this means sneezing, itchy, watery eyes, wheezing and coughing. While allergy medication can help curb symptoms of seasonal allergies, it’s important to not forget about the role your home’s HVAC system has in the air that you breathe. Depending on how you maintain your system, your symptoms could improve or be exacerbated.

Your HVAC Air Filters

Although replacing your HVAC air filters is important all year long, this easy maintenance task is especially vital during hay fever season. A clean filter serves as a first line of defense to maintain the quality of your air. Consider changing your filter at least once a month through late spring.


If you or family members suffer from significant allergy symptoms or respiratory conditions, like asthma, consider adding a HEPA filter that can remove even more of the particulates that lead to symptoms. Talk to one of our technicians about this option.


Your HVAC ducts can be harbors for dust and dirt over time. This means that when you turn on your air conditioner or heater, particulates are blown into the air – directly impacting the quality of your indoor air. Having ducts cleaned can significantly improve symptoms for many homeowners and their loved ones. It’s also an opportunity to determine if you have any leaks that hinder the performance of your system.

Enjoy the Spring

Here in the Valley, spring is primetime for enjoying great weather. Don’t let allergic symptoms prevent you from making the most of the season. Call Cool Blew today for a spring HVAC system tune-up and to answer your questions on how to improve your indoor air quality.

When Should You Turn on Your Air Conditioner?

This entry was posted in Air Conditioning on by .

We all know that spring-like weather starts early in Arizona. And this year is no exception. Temperatures are already starting to creep back up above 80 degrees. Although nights and mornings can still be chilly, many of us are tempted to turn on the air conditioner in the afternoon to cool off a bit. But before you touch that thermostat (and long before that first 100-degree day hits), it’s important to ensure your air conditioner is working optimally.

Spring Cleaning for Your AC

Like with the rest of your home, your air conditioner requires maintenance to stay in tip-top shape. Early spring is the ideal time to make sure it’s clean. This includes replacing or cleaning air filters, cleaning up dirt and debris around the exterior unit and cleaning the coil and condensate drain. If you don’t feel comfortable with any of these tasks, the team at Cool Blew is happy to help as part of preventive maintenance service.

Professional Tune Up

As part of preventive maintenance, you will also gain the advantage of having an expert technician ensure every component of your air conditioner is working optimally. If malfunctions are identified, they can be fixed in a timely manner. This means not having to experience an unexpected system failure on a summer day when cooling is critical. Even if you think your air conditioner is working fine, it makes sense to schedule a tune-up with an HVAC professional. And spring is the optimal time before the busy summer season begins.

Considering a New Air Conditioner?

If you’ve been putting off replacing an aging, inefficient system, we can help you with that, too. We provide free in-home estimates and can help you determine the best system for your specific needs. A new air conditioner will save you a substantial amount on your monthly utility bill and will improve your home’s comfort considerably.

Replace the Air Conditioner or Just the Evaporator Coil?

This entry was posted in Air Conditioning on by .

In the Valley of the Sun, weather can be tough on air conditioners. While they can run for many years without missing a beat, the elements can eventually begin to erode components – including the evaporator coils. When this happens, the refrigerant that flows through the coils can begin to leak. This is a significant repair, and often it makes sense to simply replace the unit. But this isn’t always the case.

Signs of Evaporator Coil Problems

  • Loss of cooling power
  • Registers not blowing cool air
  • Hissing sounds from the unit
  • Rising electric bills

Reasons to Replace the Unit

Your AC is 10 years or older – If you have a unit that is approaching the end of its life (10 years or older), it typically makes sense to go with replacement because of the increase in efficiency that you will gain with a newer model. Here’s another way to think about it. Replacing just the evaporator coils in an old unit is akin to replacing the engine in a car with 150,000 miles on it. It just doesn’t make sense.

Your AC uses R-22 (Freon) – If you have a very old unit that uses the now banned R-22 refrigerant (Freon), replacement is a no-brainer. This type of refrigerant is no longer being produced, which means it’s in limited supply and increasingly expensive. Regardless if it’s a problem with the coils or any other type of refrigerant leak, unit replacement is the way to go if your unit takes R-22.

The evaporator coil you need is obsolete – If you have a unit with a low SEER rating, the replacement coil may no longer be available. Mismatched coils can drag down the performance of your unit and ultimately cause a full system breakdown.

Think you may have an evaporator coil problem with your air conditioner? Considering a new unit? Call the experts at Cool Blew today.

Maximize Your Air Conditioner Efficiency in 2020

This entry was posted in HVAC Maintenance on by .

While most of us aren’t running our air conditioners in February, there’s no disputing that they are essential throughout most of the year in Arizona. So, it’s a good thing that they’re built to last and work reliably for years.

Yet, like all good things, air conditioners can be taken for granted. Most work without a problem, even in extreme heat, without missing a beat. But, if they are neglected or not properly maintained, problems can happen.

The Time to Call Is Before There’s an Issue

Consider that your air conditioning system has many components – both inside and outside of your home. These include motors, switches, fans, vents and more. They all work together to generate comfortable, cool air. Keeping this mechanical and electronic symphony playing in harmony requires regular, preventive maintenance.

Choose a Trusted Provider of Air Conditioning Maintenance and Repair

Today’s air conditioners are complicated. You want an HVAC service provider that is both highly trained and experienced. Establish a relationship so that the provider can get to know your HVAC system. The goal is to get in the habit of twice-yearly service inspections (ideally in the spring and fall), so that you don’t have breakdowns in the hot summer months or in the chill of winter. Yes, air conditioners, as well as other HVAC, parts and components can wear out or malfunction – and at different times. With regular maintenance, potential problems can be identified proactively, and parts replaced before you experience a problem.

Don’t Forget Your Ductwork

In the dusty environment that we live in, ductwork isn’t something to ignore. Ducts are vital for delivering conditioned air to every room in your house. So, if they’re loaded with dirt or mold, you and your loved ones are breathing that in. As part of HVAC system efficiency and upkeep, make sure that your ducts are checked and cleaned.

Is Your Heat Pump Leaking Refrigerant?

This entry was posted in HVAC Maintenance on by .

Just like your refrigerator and air conditioner, a heat pump requires refrigerant to work. Yet unfortunately, many homeowners don’t discover that their heat pump’s refrigerant levels are low until they’re experiencing a problem like icing or no heat.

Is It a Leaking Heat Pump?

Within your HVAC system, your air conditioner and heat pump both rely on refrigerant to provide an optimal temperature inside your home. And, it shouldn’t dissipate during operation. Instead, your HVAC system should convert refrigerant from liquid to gas and vice versa – never decreasing in volume. However, leaks can happen, and they often occur at connector points.

During the cold winter months, often the first sign of a refrigerant leak is an indoor temperature that begins to drop. You may notice that the heater seems to be running continuously. Yet, the temperature doesn’t seem to be matching the thermostat setting. If it’s getting chilly, and the heat doesn’t seem to be where it should be, it’s time to call for a technician.

What About Icing?

When a heat pump is leaking refrigerant, there’s often a snowball effect of problems. The first of these can be the heat pump’s evaporator coil. Because heat absorption is the refrigerant’s purpose, leaking refrigerant can prevent the coil from absorbing heat. This ultimately causes moisture on the evaporator coil to ice over. You may be tempted to scrape off the ice but note that this isn’t going to solve the problem. What you actually need to do is call an HVAC technician who can both seal the leak and add the necessary refrigerant to enable your system to operate efficiently.

Don’t Neglect a Refrigerant Leak

Low refrigerant isn’t an HVAC problem to put off for another day. The stress caused by this problem can leave you in the cold, as well as impact the compressor and drive up electrical costs. If you’re struggling with a lack of heat, call the experts at Cool Blew. We’re here to help you identify the cause of the problem and ensure that you’re up and running as quickly as possible.
