Happy Fourth of July HVAC Tips

This entry was posted in HVAC Maintenance on by .

Portrait of happy multi-ethnic family and friends at dining table celebrating Independence Day.

July 4th, a day to commemorate our independence, is almost here. This American holiday steeped in tradition is a day to spend time with family and friends, swimming, parades, and watching fireworks. Along with all the holiday festivities, you’ll want to enjoy indoor time in the cool comfort of air conditioning. Here are some holiday tips to help keep you and your family cool without overworking your HVAC system.

Avoid Air Filter Overload

Maybe you’re having a barbecue on July 4, and outside doors may be left open at times when guests are going inside and outside. Of course, this is when smoke from the grills goes inside putting a strain on your HVAC air filter. Before having guests over or if there has been a recent dust storm in your neighborhood, change the filter. Keep in mind, if you have pets or family members with allergies or respiratory issues, checking and replacing air filters on a regular schedule, at least every 30 days, is very important to keep indoor air quality high.

Program Your Thermostat

It’s going to be an exceptionally hot 4th of July this year. If you program your thermostat in advance, you’ll be able to keep the indoor rooms comfortable for holiday celebrations. Smart thermostats have motion sensors that can detect when you and your guests are indoors which allows the HVAC system to automatically keep everyone comfortable at a set temperature.

Use Ceiling Fans

The advantage of using your ceiling fans in occupied rooms is that they make everyone feel cooler. Ceiling fans increase airflow and can actually make the room feel up to four degrees cooler.

Schedule HVAC Servicing

Proper HVAC maintenance can help avoid holiday air conditioning emergencies during summer. Your HVAC system should be thoroughly inspected, cleaned, and serviced twice yearly. Cool Blew’s

technicians will check refrigerant levels, electrical systems, connections, and clean the evaporator and condenser coils. If you’ve put off servicing on your system, make certain to schedule an appointment today to avoid any AC issues putting a damper on your holiday celebrations.

Call Cool Blew

Summer AC and Evaporative Cooler Care

This entry was posted in Air Conditioning on by .

Caring for your air conditioning unit and evaporative cooler during summer months is especially important with the fluctuations in temperatures and humidity levels in the Valley of the Sun. An air conditioning unit has its primetime when the summer heat is on—often having to run most of the day and evening. If you have an evaporative cooler (swamp cooler), it works best when there’s low humidity before and after monsoon season. Here’s how you can avoid these common issues with both types of units.

Dust and Dirt Buildup

AC Unit

Check and change your air filter often. Summer in Arizona means monsoon thunderstorms and dust storms (haboobs) that can overwhelm your air filters. Dust and debris can clog the air filter, leading to a buildup of dirt on the evaporator coils, which makes it more difficult to send air through your system to cool down your house.

Evaporator Cooler

The biggest issue for evaporative cooling is from dust storms. The dust can clog filters, cooling pads, and cause the cooler to stop operating. If you notice decreased air flow indoors, it’s probably due to dust. If your evaporator cooler is ground mounted, you can use a soft bristled brush, or whisk broom to loosen dirt and dust that has collected in the unit. If its roof mounted, your local HVAC technician can clean it.

Mold and Mildew Growth

AC Unit

Your outdoor AC unit is designed to work in all types of weather conditions. You may think it’s a good idea to cover the unit to protect it from dirt, dust, and debris. Yet, covering the unit can result in mold growth, mildew, and corrosion. Indoors, high humidity levels over 50% for an extended period of time can result in mold and mildew rapidly growing in humid areas. Fungicides or a bleach and water mix can work on small areas. For large areas, professional mold remediation may be required.

Evaporator Cooler

Evaporative cooling units can produce fishy or dirty sponge smells. Mold and bacteria can thrive in coolers potentially resulting in respiratory and allergic reactions indoors. To eliminate this odor, the unit needs to be drained and the cooling pads and water tank removed. The pads can be soaked in lemon juice and water. A 50/50 solution of vinegar and water can be run through the cooler to minimize the smell.

Cool Blew

If you’re continuing to experience mold and mildew or other persistent smells, it may be time to call your expert technicians at Cool Blew. Call your home cooling specialists today at 623-872-2900 to schedule an appointment. Beat the heat with Cool Blew!

How Your AC Can Help Reduce Dust Inside Your Home

The Valley of the Sun is a beautiful place to live. For all its beauty, the desert is one extremely dusty place to live, and that dust can end up inside your home. Let’s take a closer look at dust and how you can use your AC as a dust reduction tool.

What’s in Household Dust?

Over time, dust can quickly build up inside Arizona homes. You’ve probably noticed this dust after vacuuming and seeing a large amount of dust particles suspended in the air. So, just what makes up household dust? Indoor dust is made up of many particulates found inside and outside your home. In a typical household, dust is comprised of fine particles of dirt, microscopic grains of sand, food debris, fibers from carpet, bedding, and clothing, particulate matter from cooking, skin cells, pet dander, decomposed insects, and dust mites. Here are a few steps you can take to reduce dust in your home.

  1. Change Your Air Filter Regularly – For most of the summer, your doors and windows remain closed to keep out the heat. Your best safeguard against dust is the air filter in your air conditioning system. As air from your home is recirculated through your AC system, the air filter traps all the little particles floating around. If your air filter is clogged with dust and debris, its effectiveness is greatly reduced, and more dust will circulate throughout your house. Plus, your AC will work longer to continue pumping out cool air through a dirty filter.
  2. Clean Air Ducts – In Arizona, dirt and dust can quickly build up in your air ducts. Often, homeowners are surprised to find out just how dirty their air ducts have become. By conducting a thorough duct inspection, your HVAC professionals can also see if there’s any water collecting inside the ducts, which can result in mildew and mold building up.
  3. UV Light Air Filtration – You may want to think about adding an ultraviolet light filtration system to help reduce contaminants from dust indoors. This added protection is an option that can help If you or a family member is suffering from respiratory issues. Cool Blew’s technicians can discuss how UV light technology works and if it’s a good option for your home.

Cool Blew

Now is the perfect time to have your air conditioning system checked and serviced. Give your servicing professionals at Cool Blew a call today at 623-872-2900 to schedule an appointment. We’ll be happy to help you minimize dust in your home and bask in cool, cleaner air.

Five Timely Tips to Save Energy and Money in Your Home

This entry was posted in Air Conditioning on by .

The heat has finally arrived in the Valley of the Sun. So, it’s prime time to focus on ways to save energy on monthly utility bills without having to make large sacrifices in comfort. You can save energy, money, and the environment with these tips.

1. Close Curtains, Blinds, and Drapes

During the hotter months, keep your curtains, blinds, and drapes closed during the daytime. This simple tip helps to keep out the sunlight and solar heat gain without the air conditioning unit continuously blasting out cool air. The Department of Energy says by smart management of window coverings, homeowners can reduce heat gain by up to 77%. Double check to make certain your fireplace damper is also closed to prevent AC air from going up the chimney.

2. Set the Thermostat Up

Setting your thermostat to at least 78 degrees or higher will decrease energy bills up to 5% per degree. Chances are you may not even notice the difference much. During the night, you don’t need the same amount of air to feel cool. By turning on the overhead fan, it can help circulate the cool air and will maintain the same level of comfort if you were to lower the thermostat by four degrees. You’ll see real savings without sweltering.

3. Close the Gaps

Gaps around your windows and doors are increasing your monthly utility bills. AC leaking through these areas can add up to an additional 15% on cooling costs. A well-sealed home means a reduction in dust, pollen, and insects entering inside. These gaps can easily be fixed with caulk, weather stripping, and door sweeps.

4. Replace the AC Filters

A well-maintained air conditioning unit simply uses less energy. By replacing the air filter to your HVAC system at least every month, you’ll gain the advantages of increased air flow, cleaner indoor air, and lower monthly utility bills.

5. Go with LED Light Bulbs

Replace any remaining standard bulbs with ENERGY STAR rated LED light bulbs. LED bulbs actually use 70% to 90% less energy and best of all last 25 times longer. The benefits of installing LED light bulbs range from a better source of light similar to natural sunlight to savings up to $1,000 over a 10-year span according to the Consumer Federation of America.

Is Your HVAC Ready for Memorial Day Weekend?

This entry was posted in HVAC Systems on by .

Memorial Day honors those who’ve died in our nation’s wars. Also, Memorial Day signals the unofficial start of summer. With excessive heat on the way in Arizona, you’ll want to make sure your house and HVAC system are ready. Your AC unit is your first line of defense for keeping your family cool and comfortable. This is when an HVAC system tune up is beneficial to ensure your system can keep pace with increased usage demands, help extend its lifespan, and even prevent costly repairs.

Maintenance is Your AC Lifesaver

Ideally, you should schedule system maintenance two times per year. It’s best to have a full inspection of your HVAC system before the Valley of the Sun shifts into extreme weather conditions. This is the perfect time to have your local experienced technicians at Cool Blew ensure that your AC unit is working properly, and the system is all set for summer. Here are some of the benefits you’ll enjoy by scheduling servicing now.

Decreased Energy Costs

Regular servicing helps to keep your AC unit operating efficiently, and it won’t have to be continuously running to cool down your home. With all components checked and serviced, a tuned-up system will help your family stay cool and safe from the outside heat. An HVAC system running less often means less electricity is consumed. This can translate to a noticeable decrease of your monthly utility bills even during the summer months.

Preventative Care

Cool Blew’s experts have the training and knowledge to work on all types of HVAC systems. During maintenance, they’ll inspect your system to identify issues and address any needed repairs on the spot. Small problems such as blown fuses, low refrigerant levels, or even a dirty air filter can turn into big problems when you least expect them. By scheduling your tune up now, you can potentially reduce the chances of suffering from expensive system breakdowns by up to 95%.

Maintain System Warranty

If your HVAC system is covered by a manufacturer warranty, a system repair claim may be denied if you can’t provide proof that you’ve had the system regularly serviced. HVAC maintenance is key to proper functioning of your AC all summer long. The cost of a tune-up will be well worth it if your air conditioning unit experiences an unexpected and costly failure.

Call Cool Blew for Your Tune Up

If you haven’t already scheduled your air conditioner tune-up, now is a great time to do so. Call Cool Blew today at 623-872-2900 to schedule an appointment. We’re open 24/7 including all holidays and weekends. Happy Memorial Day from Cool Blew!

What to Do When a Major Water Leak Happens at Your House

This entry was posted in Plumbing on by .

Most home leaks are caused by excess water pressure, broken seals, clogged lines, loose water connections, and damaged pipe joints. But sometimes there can be burst pipes inside your home that can cause major damage. You might not have experienced any major home water leaks, but you’ll want to know what to do when this type of situation occurs. Here are a few basics when it comes to major water leaks and shut off valves.

Water Shut Off Valves

When there’s a major water leak anywhere at your home, it’s vital to know where the water shut off valves are located. You’ll want to turn off the water quickly before water begins to flood the surrounding area.
For the entire house, there’s a primary shut off valve where the cold-water supply goes into your home, usually located near the front door or on the side of your house.

For water leaks at specific fixtures, there’s generally a valve behind or below the fixture to turn off the water supply.

A leaky hot water heater is a common issue that can result in a large volume of water loss. It’s one of the most used appliances in your home and the last thing you want is for it to break down and not know how to turn off the water supply. If it’s leaking, you’ll want to immediately turn off the water supply to the entire house. Then, call your local knowledgeable plumbers at Cool Blew for additional assistance.

Burst pipes inside your house can be caused by a number of factors. When a pipe bursts, it might start as a small leak, but before you know it, hundreds of gallons of water can flood inside your home. There are a number of common causes for burst pipes including aging pipes, slab shifts, pipe clogs, and tree roots growing into pipes. Immediately turn off the water to your entire house and call your plumbing experts at Cool Blew for help.

When to Call a Pro

Best Reasons to Change Out Your HVAC Air Filters

This entry was posted in HVAC Maintenance on by .

An important part of maintaining your HVAC system includes changing air filters to keep your indoor air clean. Most Valley of the Sun heating and cooling professionals recommend a twice-yearly check-up of HVAC systems to keep them running efficiently, reducing energy costs, and extending the lifespan of these units. Changing out air filters can lower monthly utility costs by up to 15% in the Valley of the Sun. Let’s take a look at some of the best reasons to check and change out your air filters.

Importance of Air Filters

Your first line of defense against dust, debris, and allergens from entering your home is your HVAC system’s air filtration. An HVAC system works by bringing air into your house by way of the heating or cooling system. It’s important that this air getting heated or cooled is clean, and the air filter is what keeps the air clean indoors. A clean air filter reduces contaminants such as dust, debris, mold spores, pet dander, bacteria, and other household allergens.

Reasons to Change Air Filters

When air passes through the filter, microscopic particles of dust and debris get trapped by it. These particles eventually become so widespread that it’s difficult for air to pass through. When the air filter becomes clogged, many issues can occur impacting your HVAC system and energy costs. Also, when your HVAC system works harder, it releases even more carbon monoxide and greenhouse gases into your home’s environment. Changing out your air filter takes less than five minutes and is one of the easiest and most inexpensive things you can do to keep your system running smoothly all year long.

When to Change Air Filters

The EPA recommends changing out air filters at least every three months. Your family may benefit from changing out air filters more often for these reasons:

  • Family members with allergies, asthma, or other respiratory issues
  • Young children at home
  • Smokers in the home
  • Long-haired cats or dogs
  • Elderly family members

In these situations, you may want to consider changing out your air filter monthly. Replacing your air filter at the same time each month, when you pay the utility bill, helps develop a regular habit to maintain clean indoor air.

Cool Blew professionals are your local experts in understanding HVAC air filters. Call us today at 623-872-2900 to schedule your maintenance visit and check your air filters.

How Your HVAC System Helps with Spring Allergies

In the Valley of the Sun, spring means a fever pitch of beautiful wildflowers, blossoming trees, and the Sonoran Desert hiking trail areas in full bloom. Spring is also the time of year when Arizona residents who are sensitive to allergy triggers encounter a great deal of discomfort. There are dozens of native and non-native species of plants, trees, and weeds that can cause a whole slew of allergies. The other big trigger for allergies in Arizona is dust.

The great news is your HVAC system is the command center for your indoor air quality which can help you limit exposure to prolific pollinators, such as thistle, ragweed, mulberry, and juniper. Distressful signs of allergic rhinitis, commonly called hay fever, include coughing, sneezing, wheezing, nasal congestion, fatigue, headaches, and itchy, watery eyes. Let’s take a look at how your HVAC system can help with spring allergies.

Best Ways to Achieve Pollen Free Clean Air Inside Your House

According to Statista, about 49% of adults reported they had seasonal allergies and about 27% said someone in their household suffered from seasonal allergies in 2021. You can take these three steps to lower the effects of pollen and other allergens inside your house by:

1. Change Out Your HVAC Air Filters

Replacing air filters on a regular basis helps eliminate pollen, mold, smoke, and dust from getting into your AC system in the first place. As wind-blown allergens float through the air, your HVAC air filter forms the first line of defense in safeguarding your indoor air quality (IAQ).

2. Add a Pollen and Dust Collector

For individuals with high sensitivities to allergies, high efficiency particulate air (HEPA) filters remove more than 99% of particles. These special HEPA filters can be added to your existing HVAC system. Our certified service technicians will be happy to discuss the benefits of adding a HEPA option as another line of defense for improving your home’s IAQ.

3. Schedule Time for a Spring Tune Up

One of the best things you can do for your family’s health and for your air conditioner is to schedule a spring inspection of your entire HVAC system.

Call Cool Blew for Cleaner Indoor Air

When you schedule a spring HVAC system tune up today at 623-872-2900, our technicians can help you pinpoint any potential air quality issues that may be affecting your health. We’re here 24/7 every day of the year to help ensure your home’s air is as pure as possible.

Common Air Conditioning Myths

Common Air Conditioning Myths

Here in the Valley, we all rely on our AC when daytime temperatures begin rising in spring. You don’t want to waste your time or energy by buying into false rumors about air conditioners. Whether myths come from your neighbor or a less than scrupulous HVAC service provider, they can hinder your ability to maximize the efficiency of your system. Our Cool Blew expert technicians want to share four common air conditioning fallacies and bust them wide open.


Running your air conditioner lets in dust and other allergens.


Turning on your AC will actually keep out most dust and allergens from impacting your indoor air quality. HVAC air filters, depending on the level of filtration, will filter out dirt, dust, dander, viruses, bacteria, smoke, and volatile organic chemicals from entering your home.


Closing most AC vents will save energy.


Closing most of your home’s AC vents will not lower your energy bills. The HVAC system is designed for the air handler or blower to move a certain amount of cool air inside your house. Closing too many vents will reduce the total amount of cool air moved by the AC blower, which reduces its working efficiency. Only close doors and vents in unused rooms.


To cool down your home faster, you should turn the thermostat six to 10 degrees below the desired temperature until your home is cool.


Lowering the temperature on your thermostat below your desired temperature doesn’t enable your air conditioner to work any faster. It just extends the amount of time that your air conditioner is running, which uses even more energy, and over time can result in shortening the HVAC system’s lifespan.


It’s best to turn your air conditioner off when you’re away from home to save energy.


When temperatures hit above 95 degrees outdoors, it can climb well into the 80s or low 90s inside your house when it’s not being cooled by an air conditioner. When the AC is turned back on, the unit will have to work longer to cool down your house. The most energy efficient solution is to raise your programmable thermostat up by six to nine degrees during the hours you’ll be away. If you have pets or heat sensitive plants or home furnishings, it’s best to not change the AC setting.

HVAC Energy Saving Tips for Earth Day 2023

HVAC Energy Saving Tips for Earth Day 2023

Earth Day is observed on April 22 as a global effort to change what we do in our daily lives to make planet earth a better place to live. Over five decades since Earth Day’s founding in 1970, climate change and how to mitigate its effects is front and center internationally. Every action, no matter how small, can help change our environment for the better.

According to some estimates, HVAC systems account for 28% of the world’s total greenhouse gas emissions. Proper maintenance and efficient HVAC operations can make a real difference in building a healthy, sustainable world. Here are four helpful tips to conserve energy and ensure your HVAC system is running as smoothly as possible in the greater Phoenix metro area.

1. Use Your Window Coverings

A simple trick to decrease energy consumption is to close your curtains, drapes, and blinds. This is the perfect way to help control temperature inside your house. In the cooler months, you can keep them open letting the sun’s rays heat your home. In the warmer months, keep your window coverings closed during daytime hours to reduce the radiant effects of the sun.

2. Check Your Filter

The easiest way to make certain your HVAC system runs efficiently is to check and change your air filter at least monthly. An air filter clogged with dirt, dander, and debris disrupts the airflow through your heating and cooling system making it work longer which increases your monthly energy bills.

3. Tune Up Your HVAC Equipment

By adhering to regular maintenance, you’ll be on the way to saving energy and money. That means scheduling twice yearly servicing on your air conditioner and heating system. By having your system checked by a trained HVAC professional, you’ll ensure it’s operating at its most efficient level and that all components and parts are in good working order. This will catch any issues before they become costly.

4. Seal Your Heating and Cooling Ducts

Sealing your heating and cooling ducts is vital to the health of your HVAC system. Air ducts are designed to move air from your heating and cooling system throughout your house.
