Summers in Phoenix

Tuesday, May 5th, 2015

Summers in Phoenix mean two things for residents: high energy use from running air conditioners and the resulting high energy bills. That’s the bad news, but the good news is that you don’t have to stress about the summer anymore!


  • Stop being afraid of opening your energy bill.
  • Even though we live in the desert, the amount of dust in your home can be reduced.
  • South and west facing rooms are often the hottest in your home.
  • You and your family can have relief from the symptoms of allergy and asthma.
  • You don’t need the thermostat set at a higher (and uncomfortably warm) temperature just to save money.

The technicians of John’s Refrigeration are trained to assess and solve these and other problems related to the cooling system of your home.

Oftentimes our customers wait until the problem is bad without realizing that we offer ongoing maintenance plans so that we can catch and fix problems before you need a new system. We want you and your family to be healthy and comfortable in your home; especially during the hot Arizona summer!

If your system is 8-10 years old or more, we can replace it for as little as $25 per week.

Just Call John’s and one of our Comfort Consultants will visit your home, evaluate the needs of your family and system, and design a plan that fits your budget. Our solutions are 100% guaranteed!

What MERV Rating Means for Your Air Filtration

Monday, April 27th, 2015

We are right now in the middle of allergy season, when even people with minor allergies and asthma can start to experience uncomfortable symptoms from the pollutants circulating through the air. At Johns Refrigeration, we take indoor air quality very seriously, and we want you to have the most pleasant conditions in your home as possible. We install a variety of filtration systems that will remove most of the allergens moving through your home’s air. (more…)

The Sensi Wi-Fi Thermostat is Only 1 Way to Save (As seen on Sonoran Living Live)

Thursday, April 23rd, 2015

Before summer gets here, take some easy steps now to lower your utility bills.

  • Change air filters monthly. Your HVAC system has to work harder if the filter is clogged. If you tend to forget about it, replace your filter when you receive your utility bill. Or Just Call John’s to join our filter service and we’ll bring out a year’s worth of filters so you have them on hand.
  • If you have an electrostatic air filter, then you only need to clean it once a month – not replace it.
  • Replacing window screens can do a lot towards lowering utility bills. Bug screens keep out bugs, but not the heat of the sun. Installing shade screens – or calling John’s to do it for you – can save you a lot of money.
  • Consider replacing your thermostat with a Sensi Wi-Fi Thermostat. This thermostat learns your schedule and what temperature you like your house to be. You can control more than one room at a time with a wireless sensor, and even control the temperature of your house while you’re at work or on vacation.

John’s can help you with filters, shade screens, and programmable thermostats. Installing a Wi-Fi thermostat provides remote access from your smartphone, tablet, or PC, which means you’ll be able to save a lot on your energy bills

John’s also offers a free in-home evaluation can see where heat is coming into your home to determine what kinds of adjustments to your cooling system can be made.

Ductless Systems and Your Indoor Air Quality

Monday, April 20th, 2015

The spring season is also the peak of allergy season. If there are people in your home with asthma or allergy problems, this period of the year can often be a rough one, with an increase in the cold- and flu-like symptoms associated with allergies and unpleasant asthma attacks.

There are many ways you can help raise indoor air quality in your home to alleviate the hassles of allergy season, as well as allergy and asthma hassles around the year. Johns Refrigeration offers a number ofexcellent solutions for cleaning the indoor air in your home, including UV lights and electronic air cleaners. There is another, more extensive solution you may consider if you are also planning to install a new air conditioning system or new home construction lies in your future: a ductless mini split heat pump.

How does a ductless system help with allergies and air quality?

Most indoor air quality remedies are designed to remove the contaminants that circulate through the air of a home: filters, purifiers, etc. But what if you could remove the location where most of these contaminants gather? That would eliminate the bulk of them. This is what switching from a standard ducted central heating and air conditioning system to a ductless mini split heat pump achieves.

The ductwork of a home is a major spot for pollutants to gather. The airtight seal inside the ducts makes it easy for dust, dirt, pollen, dander, and numerous other allergens to begin to build up. Ducts don’t receive routine cleaning during the week like many other parts of your home, so this level of debris will continue to grow with no escape except into your home’s air.

But ductless mini split heat pumps have no ductwork at all. They instead send conditioned air directly into rooms through wall-mounted air handlers. These air handlers connect to an outside unit, so they are still central systems with much more power than window air conditioners; but their direct cooling and heating power means they can bypass ducts and the contamination that develops inside them. The result is a significant drop in the allergens moving around your home.

Call Johns Refrigeration in Mesa, AZ and throughout the Valley of the Sun to find out more about ductless mini split heat pump installation. We are glad to help you with any other indoor air quality installations that will make your home healthier place.

Plants That Trigger Allergies (and how a whole home air filter can help)

Thursday, April 16th, 2015

Are you experiencing sneezing, wheezing, nasal congestion, a runny nose, or itchy, watery eyes? You might be experiencing allergies associated with the plants, flowers, grasses, trees, and weeds that are currently in bloom. While we need rain in the desert, it is making for a terrible allergy season. What can you do at your home to prevent triggering allergies? You can start by avoiding plants that trigger allergies.

What are allergies?  

When you have an allergy, you have a heightened sensitivity to an allergen – a foreign substance. Common allergies include dust, pollen, and pet dander. Your body overreacts when it encounters allergens, causing the immune system to go into overdrive. When this happens, you experience runny nose, itchy, watery eyes, and other symptoms.

Arizona Plants that Trigger Allergies

Arizona, especially the Phoenix area, is a place where native and non-native plants that trigger allergies exist together. If you can avoid some of these, you will experience fewer allergy symptoms. Native plants include a species of ambrosia called triangle lead bursage, mesquite, and Palo Verde. Non-native olive, white mulberry, Russian thistle, and common grasses including Bermuda, fescue, and perennial rye all trigger allergies.

Tips for Dealing with Allergies

Being uncomfortable during allergy season is bad enough, but if allergens in your home are causing you to sneeze, have itchy eyes, or experience other symptoms, it’s time to make a change.

  • Keep the house at a normal level of humidity to keep allergens like dust mites from reproducing.
  • Close windows and doors during high pollen days.
  • Obey the no-burn days.
  • Avoid down comforters and pillows.
  • Replace carpeting with tile or laminate flooring.
  • Take shoes off at the door so you’re not tracking dust, dirt, and other contaminants into the home.
  • Keep pets off your bed or out of bedrooms.
  • Regularly bathe pets to cut back on allergy inducing dander.

At John’s Refrigeration, we often recommend installing a whole home air filter that will decrease the dust, pollen, and other contaminants in the home. Kitchen and pet odors will be nearly non-existent and the air in your will be clean and allergen free. Just Call John’s today to learn more.

Is Dry Air in My Home Really That Much of a Problem?

Monday, April 13th, 2015

A “dry heat” usually has a positive meaning. When the humidity rises along with the temperature, it makes the hot weather feel substantially worse. The extra moisture in the air creates a heat seal around the human body that restricts the body’s ability to release heat from the skin. The trapped heat makes the actual temperature feel hotter and less bearable. But if there is little moisture in the air, heat can escape from the body much faster, and so the heat doesn’t seem as bad. (Although a 110°F summer day in Mesa is still hot, no matter the humidity.)


Ways to Raise Awareness about Allergy & Asthma Awareness Month

Thursday, April 9th, 2015

May is the height of allergy season, making it the perfect time for Allergy & Asthma Awareness Month. The Asthma and Allergy Foundation of America promotes the education and increased awareness of allergies and asthma across the nation. Their mission is to help communities understand the impact of environmental and food allergies to their citizens.

While John’s Refrigeration isn’t an expert on food allergies, we know a few things about creating a healthy environment in the home. Dust, pollen, dirt, and other contaminants can make it a struggle for many people to be outside. We make it our mission to help our customers breathe easy in their homes.

Did you know….the air in your home can be dirtier than the air outside?

It’s true. Your home can actually suffer symptoms of difficulty breathing, a sort of asthma attack inside the home. This occurs when the ducts are not sealed properly and/or when you’re not using a properly sized air filter. These conditions cause the system to work harder – breathe heavier. You see the effect of this extra effort in the form of higher utility bills.

What can you do to treat the asthma of your home?

The simple answer is to Just Call John’s. Our team of certified technicians will come to your home, assess the current system, make recommendations for repairs and upgrades, and get your home breathing easy. We also perform valuable services to make sure your home is breathing easier:

  • Test Indoor Air Quality to understand if there are allergens and contaminants making you or your family feel less than healthy.
  • Perform an Energy Audit to determine where your home is costing you money and energy efficiency.
  • Join the Peak Performance Club, which provides annual maintenance to the entire system of your home. We can catch repairs before they become replacements.

Raise awareness about Allergy & Asthma Awareness Month this May when you Just Call John’s to have the air in your home tested. Here’s to your health and comfort!

Mold vs. Dust Allergies in Phoenix

Thursday, 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.

If you’re concerned or curious about the indoor air quality of your home, Just Call John’s at 480-718-1172 to schedule an appointment.

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

Thursday, 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

Wednesday, 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.
