Ways to Celebrate Arbor Day in Mesa

April 2nd, 2015

What is Arbor Day and how can you celebrate? Arbor Day was established in April 1872 by J. Sterling Morton. He was a journalist from Nebraska who felt Nebraska’s landscape and economy would benefit from planting trees. The sentiment spread beyond Nebraska and today all 50 states and many countries around the globe celebrate Arbor Day by planting trees and educating communities on the benefits of trees.

This year we celebrate Arbor Day on April 24th.

Become a Member of the Arbor Day Foundation

The Arbor Day Foundation inspires people to plant, nurture, and celebrate trees. If you’ve ever wanted to know the difference between a weeping and desert willow tree, the anatomy of a tree, or hundreds of other facts, visit The Tree Database. You can also find information about companies supporting the environment with tree planting. Become a member of the Arbor Day Foundation and receive benefits, including 10 free trees, planting trees in rainforests, and planting trees in our national parks.

Get Named Tree City USA

If you live in Mesa, where John’s Refrigeration is based, you already live in a Tree City USA. In 2014, we celebrated the award given to us for having the ability to improve urban forests and educate the community on the importance of trees for communities and the environment. Celebrate this year by planting a tree!

Add Xeriscape in Your Yard

Not interested in planting trees in the desert? We can’t blame you as they need a lot of water to grow, especially when they are young. Consider xeriscaping instead, a low water-use landscape technique that preserves desert plants and conserves water.

Other ways to celebrate Arbor Day include reading about trees, visiting Boyce Thompson Arboretum in Superior, attending a class about plant care and maintenance, and spending time outside. The greener we can make our communities, the better we will be!

How can You tell when You Need a New Heating Installation?

March 30th, 2015

After going to all the trouble of selecting and installing a new heating system, no homeowner can be blamed for wanting that system to last as long as possible.

With proper care and maintenance, you can probably get your heater to last a couple of decades or more. No matter how well you take care of it, however, it will eventually reach the end of its life. When that happens, you should be able to recognize the signs. Read on to find out how you can tell when you need a new heating installation.

Repair Costs

Every heating system is going to need repairs at some point during its life. However, you really shouldn’t have to get your heater repaired more than once every year or two. That tends to change once your heating system gets past a certain age, though. As a heating system gets older, the parts that make it up begin to wear out. As each part wears out at a slightly different rate, you can end up with this cascade of part failures that results in your heating system needing repair every few months. If this happens, it’s a pretty good indication that you need an entirely new system.

Cost of Heating Goes Up

You’re going to experience slight fluctuations in your heating bill from month to month as your demand changes. If your heating bills start rising consistently, however, then you may have a problem with your heating system. That same wear and tear that can cause cascade failures in the system also causes the system as a whole to operate less efficiently. As efficiency goes down, the system has to stay operating for longer and longer to achieve the same results. This is why the cost of your heating will go up with an older system.

Age

The general rule with heating systems is that if your heater is older than 15 years, it is time to think about replacing it. Even if the heating system itself is working fine, there are likely much more efficient heating systems on the market that could save you money. If your heating system is younger than 15 years, then you could probably squeeze a few more years out of it before it needs replacing.

If you think you need a new heating system, call Johns Refrigeration. We provide heating installation throughout Gilbert.

Mold vs. Dust Allergies in Phoenix

March 26th, 2015

When was the last time you sneezed or had a sinus headache? If you’re in Phoenix, you may be suffering from mold or dust allergies. Desert air is dry most of the year and when it’s more humid, like during monsoon, it is the perfect environment for mold to grow.

Dust Allergies in Phoenix

Have you been outside or driving in a dust storm? You can feel the grit on your teeth and in your hair. That’s dust and if you’re sneezing, you may have a dust allergy; one of the most common allergies. Even if you’re not in a dust storm, you may notice your throat is scratchy on windy days or you’re sneezing at certain times of the year. It’s probably when there are higher counts of pollutants, including dust, in the air.

Stop Dust in Your Home

To prevent dust from entering your home, we recommend removing shoes at the door. If you work outdoors or in a dusty environment, we also recommend taking your clothes off and washing them as soon as you get home. This will keep dust, pollen, and other contaminants from entering the air of your home.

Mold Allergies in Phoenix

When you think of Phoenix, mold allergies may not be top of mind, but it’s a common allergy. Mold grows in dark, humid environments indoors and outdoors. Most commonly found indoors in bathrooms or basements, mold sheds tiny spores and it’s these spores that trigger allergic reactions.

Mold allergy symptoms include coughing, wheezing, rash, runny nose, itchy, watery eyes, and redness of the eyes. While allergy medications can help fight these symptoms, getting rid of the source – the mold – is key to feeling better. Controlling the humidity in the home using a whole home humidifier will also prevent mold and mildew from growing.

How Duct Sealing can improve Your Air Conditioning

March 23rd, 2015

Ductwork is what makes centralized air conditioning possible. Without ducts, you would likely be stuck using fans and opening windows in order to cool your home on hot days. Though they are very important to the operation of central air conditioning systems, ducts are almost always neglected when it comes to required maintenance.

Let’s take a look at one of the biggest problems that ducts face, and how duct sealing can take care of it for you.

Duct Leaks

Ducts may seem pretty unlikely to develop any serious issues over the years. After all, they don’t have any moving parts. They just kind of sit there, providing a passage for cool air to travel to its destination. What could possibly happen to cause a major duct problem? Well, the biggest problems that ducts face is that of leaks, and they can happen all sorts of ways.

Improper installation can leave large gaps between the sections of ductwork. Animals can occasionally get into the ducts and tear holes in them trying to escape. Excessive moisture can cause sections of the duct to rust away, opening holes in the network. Even normal use can result in leaks, as the ducts expand and contract with the temperature of the air moving through them. This can eventually cause them to work themselves loose.

So, why are duct leaks such a big deal? Even though duct leaks are often small, they tend to add up very quickly. The US Department of Energy has estimated that the average forced air system loses as much as 30% of its output to duct leaks. That translates to a very large amount of the air conditioning that you’re paying for going to waste every time you turn the system on.

Duct Sealing

Duct sealing is the process of finding and closing any leaks that may be present in your home’s ducts. By doing this, your HVAC technician can save you hundreds of dollars a year on your electric bill. The better sealed your ducts are, the more efficient your air conditioning system will be. It is recommended that you have your ducts professionally sealed at least once every two years.

If you haven’t had your ducts sealed in at least that long, call Johns Refrigeration. We provide air conditioning services throughout the Gilbert area.

What’s the best level of humidity in your home?

March 19th, 2015

What the Level of Humidity Has to Do with the Health of Your Home

What’s the best level of humidity in your home? Humidity is the amount of moisture in the air. When it rains in Gilbert and the air feels “sticky,” you’re feeling high humidity levels. The right level of humidity in your home should be 35-45%. It’s enough to keep you healthy without feeling like the air is too heavy with moisture. While the level will vary depending on the weather, it should remain within a healthy range of 25-55% at all times.

What happens if the level of humidity is too high or too low?

While it doesn’t happen as often in Arizona as it does in other parts of the country, high humidity (more than 55%) causes the growth of dust mites, mold, and mildew, especially near water like in the kitchen and bathroom. Your towels don’t dry when you hang them up after a shower. There may be condensation on windows and the air smells musty when the level of humidity is too high. Many homeowners install a dehumidifier to draw moisture from the air in their homes.

We tend not to have the challenge of high humidity in Arizona

We usually have low humidity (less than 25%) through most of the year in Arizona. The exception being during rainy days or monsoon. The rain water evaporates quickly, leaving the air dry. With low humidity, we’re more prone to getting a cold or sinus infection, have difficulty breathing, experiencing static electricity, a bloody nose, or suffering with dry skin. If you’re using a portable humidifier, also called a vaporizer, you’re probably feeling better than you did without it. You’ve added humidity to reach a healthy level (25-55%).

Protect Your Assets

In addition to keeping you and your family comfortable, protect your assets with a healthy level of humidity in the home. Wood surfaces and flooring, musical instruments, furniture, art, and photographs can all be damaged when humidity is too high or too low.

If your family is suffering from the effects of a low level of humidity in your home, it’s time to consider a whole home humidifier. Just Call John’s at 480-648-2400 to find out how we can help you feel more comfortable in your home.

Why You Should be Concerned About Low Humidity

March 18th, 2015

There are lots of places in our country where excessive humidity is a big problem, but where we live, we can have the opposite problem: too little humidity. Humidity in a home needs to be balanced in order to be truly comfortable, and having too little humidity causes a number of problems.

The good news is that you can seamlessly add humidity to your home in Chandler with the installation of a whole-home humidifier. When you install a whole-home humidifier, it becomes a part of your entire HVAC system, so it’s important to hire an expert for installation, repair, maintenance or replacement. The technicians at Johns Refrigeration bring two generations’ worth of whole-home system experience to every job, so if you have concerns about your home’s humidity levels, call us today!

Effects of Low Humidity

Low humidity effects both people and your home in the following ways:

  • Dries out wood – most homes have a considerable amount of wood, from flooring to ceilings to furniture. When wood doesn’t have enough moisture it dries out, which leads to shrinking and eventually splintering. The end result can be irreversible damage.
  • Dries paint and wallpaper – paint can peel and bubble without enough moisture and wall paper can become unglued and start to tear.
  • Dries mucous membranes – too little humidity in your home can dry out your mucous membranes, which can lead to dry eyes, nose bleeds and dry skin.
  • Temperature discomfort – humidity holds heat, so if there is too little in your home, your air conditioning won’t feel as comfortable. As a result, you may set your thermostat lower than it has to be because even though the air is cool, it may not feel that way.

The EPA estimates that indoor humidity levels should range between 30%-60% at all times. When the level in your home sinks below 30%, you may see the above-listed problems ensue. A whole-home humidifier eliminates these problems by integrating directly into your existing HVAC system and supplying your home with the needed moisture to make it comfortable year-round.

If you are interested to see what a humidifier can do your for Chandler home, call the indoor air quality professionals at Johns Refrigeration today and schedule an appointment.

Consider a Humidifier to Help with Allergies

March 12th, 2015

How Can Humidifiers Help Your Allergies?

Do you suffer from allergies living in Arizona? You’re not alone. The heat and lack of humidity causes dry sinuses and skin, pressure, pain, and bloody noses. Humidifiers can help and here’s how:

What’s humidity?

It’s the amount of moisture in the air. When it rains and the air feels “sticky” or heavy, you’re feeling humidity and it’s needed to keep sinuses moist and functioning in a healthy way. When the air is too dry, you’re more susceptible to getting sick, having bloody noses, and feeling sinus pressure. Using a humidifier, even just one used at night, can help you feel relief from these symptoms.

Types of Humidifiers:

  • Steam vaporizers like the ones you may use when you or your children are sick boil the water into a cold or warm vapor. Vaporizers keep sinuses moist throughout the night to prevent bloody noses and coughing.
  • Impellar humidifiers rotate disks, flinging water into a cool fog.
  • Ultrasonic humidifiers use frequency vibration to create droplets of cool water.
  • Wick systems use a fabric wick to draw water from the reservoir while a fan blows the vapor into the air. These self-regulate depending on the amount of humidity in the air.
  • Whole Home Humidifiers are built into a home’s HVAC unit, keeping humidity at equal levels throughout the home at all times of the day and throughout the year.

In addition to humidifiers, we recommend the following to decrease allergens found in your home:

  • Pollen can aggravate allergies. If you spend a lot of time outside, we recommend taking your clothes off right when you enter the home, rather than tracking pollen, dust, and other contaminants through the house.
  • Take off your shoes at the door. Leaving shoes at the door when you enter means less allergens are brought from the outside and spread throughout your home.
  • Less carpet, more wood and tile flooring. While you might like the soft, warm carpet under your feet, it’s one of the worst things to have in your home, especially if you have allergies or asthma, because it holds dirt, dust, pet dander, and other allergens.

Just Call John’s at 480-718-1172 to learn how we can help you decrease allergens and increase humidity in your home with humidifiers.

Airborne Contaminants and What to Do About Them

March 10th, 2015

As you sit here reading this, you are likely inhaling millions of microscopic particulates. Most of these are harmless, and those that can cause harm are often not in high enough concentrations to be a threat. Under certain conditions, however, these airborne contaminants can lower your quality of life. Let’s take a closer look at what these airborne contaminants are, what they can do to you, and how to get rid of them.

Airborne Contaminants

You’re probably already aware of a few of these contaminants, especially if you have allergies. Dust and pollen are quite common in homes, and cause allergy attacks in many people. Those aren’t the only lung irritants floating around, however. Dust mites, insect dander, pet dander, and mold spores are common as well. All of these can inflame sinuses, as well as cause sneezing and coughing fits. The other contaminants are, unfortunately, even worse.

Viruses and bacteria are present in many homes, as well. The common cold and flu viruses are both communicable through the air, and are the most common illnesses contracted this way. Oftentimes, the airborne germs in your home are too few to penetrate your body’s natural defenses. There are a few exceptions, however. If someone else in your home becomes sick with one of these, the number of viral or bacterial cells in the air will definitely rise. Low humidity in your home can also lower your body’s defenses by drying out the mucus membranes in your sinuses. This makes infection more likely. So, what can be done about these airborne contaminants?

Duct Sealing

The ducts in your home are often a haven for germs and other contaminants, due to their dark and out-of-the-way qualities. These contaminants tend to enter the ducts through leaks and other gaps, then build up in the ducts until a forced air system is turned on. At that point they are circulated throughout the house to infect people.

Duct sealing finds and closes any leaks in the ductwork, preventing contaminants from entering the ducts in large numbers. Duct sealing can also include the application of antiseptic to the inside of the ducts, to kill any harmful germs that may already be present.

If you haven’t had your ducts sealed in a while, call Johns Refrigeration. We provide duct sealing throughout the Scottsdale area.

The Importance of Air Filters (as seen on Sonoran Living Live)

March 5th, 2015

Our owner, Andrew John, was recently featured on the TV show, Sonoran Living Live, where he spoke about the importance of air filters.

Your Home Breathes

Just as we inhale and exhale, so do our homes. There are some filters on the market that prevent the home from breathing efficiently by blocking air flow. Other filters just prevent dust from getting to the coil without filtering the air in your home.

In this segment of Sonoran Living Live, Andrew John talks about the role of the air filter, which is to filter air from the home before it enters the HVAC system.

 

 

It’s important to have the right size and type of filter. When the filter is clogged, dust and dirt are blown back into your home, causing allergies or asthma. Changing the filter on a regular basis or utilizing a reusable filter like the one Andrew talks about in this segment is one of the best ways to keep the system running efficiently.

Did you know an air filter was originally meant to just keep dust and dirt from the coil of the A/C unit?

When most people think of an air filter, we think it prevents dust from entering the home, and while that’s true, it wasn’t always the case. The original purpose of the filter was to keep dust and contaminants from getting to the coil of the unit. When the coil of the unit is covered in dirt, the entire unit runs less efficiently. You’ll see the result in increased utility bills.

Depending on the type of air filter you choose, you can protect the coil while also filtering the air in the home. But air filters are just part of the system. The box, as we like to call it – the A/C and heating unit, ductwork, and air filter – work together to make your home efficient and healthy. When one isn’t working properly, it overworks the system, making it less efficient.

If you’re unsure about which air filter to select, Just Call John’s at 480-648-2094.

 

Common Repair Issues with Commercial HVAC

February 27th, 2015

A broken commercial HVAC system may be cause for alarm during very hot or especially cold weather. If business must be put on hold due to uncomfortable conditions for clientele and employees, you may end up losing a lot of money. Keep your unit from breaking down in the middle of a busy day by scheduling repairs at the first sign of trouble.

When you receive complaints about the HVAC system in your building in Tempe, call Johns Refrigeration as soon as possible. We can address any of the following problems or aid in solving any issue that comes your way.

  • Poor heating or cooling: A commercial heating and AC system is made up of a lot of complex components. While all of these components are necessary in maintaining ideal conditions, there’s also a lot that can go wrong. When one part is not working properly, it may have an impact on several other components within the unit. If you notice that your property does not seem to reach the temperature on the thermostat–even by just one or two degrees–call a technician now so you won’t have to deal with more costly repairs later on.
  • High energy bills: Chances are, you’re never thrilled about your office’s utility bills when they cross your desk. But if you’re worried about your commercial unit, don’t just simply make an automatic payment without paying attention to the cost. Check to make sure there are no major differences from month to month, or from year to year in the same season. A spike in costs could indicate trouble.
  • Loud noises: Sometimes, strange noises from the HVAC unit mean that repairs are urgent. Other times, it could just indicate a loose panel or screw is clanking around, disrupting the work environment. Regular maintenance can help prevent even the smallest of problems from disturbing your property.

Maintenance involves cleaning, adjusting, and inspecting the unit, a job that a trained technician is best qualified for. Call Johns Refrigeration today for maintenance or any repairs you may need for yourcommercial HVAC system in Tempe.
