Consider a Humidifier to Help with Allergies

Thursday, 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.

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

Thursday, 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.


How important is it to breathe clean air in your home? (As seen on Sonoran Living Live)

Tuesday, February 24th, 2015

Our owner, Andrew John, was recently featured on the TV show, Sonoran Living Live, where he spoke about keeping the air in your home clean.

Did you know the air in your home can be dirtier than the air outside? It’s true and we have a solution.

The whole home air purifier is the solution to cleaning the air in your home.

We don’t always see what’s in the air. Dust, pollen, smoke, pet dander, odors, bacteria, and viruses are in our homes making us feel sick and our homes smell not-so-fresh. Pets, garbage, and cooking odors are among the top smells our customers want eliminated from their homes.

Getting dust, pollen, dirt, and other contaminants out of the air is especially important if you or members of your family have chronic allergies and asthma.

How many air purifiers do I need in my home?

You need as many purifiers as you have A/C units for your home.

How often does the air purifier run?

Ideally, the air purifier runs when the central fan is running in your home. We recommend the air purifier run 24 hours a day, just like the one at Andrew’s house.

How does it work?

There is a catalyst and a light that help kill bacteria and viruses, and they also clean the odors caused by pets and cooking.

Call 480-648-2094 to schedule your FREE in-home consultation to determine if an air purifier is right for your home.

Is Arizona Air Quality Getting any Better?

Tuesday, February 10th, 2015

When it comes to Arizona air quality, the Environmental Protection Agency (EPA) has deemed it improved and within federal standards. The changes were focused in Maricopa County, where about 80% of the state’s population resides. Focus is now moving to Pinal and Yuma counties, where there is still a need to improve air quality.

What happens when air quality is poor?

At John’s Refrigeration, we talk a lot about indoor air quality, but the air outside is just as important. Breathing conditions, including asthma and allergies, are worse when air quality is low. You sneeze more. Your chest feels heavier and you may be getting winded when you’re exercising outside. These are all signs of poor air quality.

What was done to improve Arizona air quality?

Eric Massey, Air Quality Division Director at the Arizona Department of Environmental Quality, said the number one reason improvement happened was partnership of local, state, and national stakeholders, including the EPA. They came together to offer “common solutions to common air quality problems.” [Source]

What were the challenges?

The biggest challenges to improving Arizona air quality were:

  • Best practices that work in other parts of the country weren’t going to work here due to funding and climate.
  • Cost of improvements and compliance monitoring was limited.

For example, in many places, watering the dust is a way to keep air quality at an acceptable level. In Arizona, we don’t have enough water to do this, so officials had to look at other solutions.

Another example is that Arizona doesn’t have funding for the number of air quality inspectors that we need. By creating solutions that were acceptable across a variety of industries and government entities, we created an organically compliant system. Each agency had a stake in improving – and continuing to improve – air quality. That means less inspectors are needed.

What can we do to maintain this level of air quality?

Over the winter, we hear about no-burn days being in effect. These are days designated by the Arizona Department of Environmental Quality and Maricopa Air Quality Department as days when wood-burning fireplaces, chimineas, and other wood burning sources are not to be used. Burning on these days traps particulate matter that aggravates breathing problems and puts young children and the elderly at greater risk.

Complying with no-burn days is a way to directly help your neighbors breathe easier, as well as help the county and state maintain a healthy level of air quality.

Improving air quality in AZ is a team effort of agencies, businesses, and neighbors who have a collective mission to keep air quality at safe and healthy levels.

How Professionals Perform Air Duct Sealing

Monday, February 9th, 2015

The wind blowing through your hair can be a great feeling when in a car, but not so much when it’s happening because of faulty ductwork in your home.

The average duct system has a lifespan of about 30 years, but that doesn’t mean it remains in pristine shape the entire time. Ductwork can corrode, become damaged or disconnect at the joints, and all this can add up to serious air loss inside your home. So what can you do to reduce or even eliminate the effects of faulty ductwork? Call Johns Refrigeration and schedule an appointment for duct sealing in your Phoenix home.

What Is Duct Sealing?

First, let’s tell you what duct sealing isn’t: putting a piece of duct tape on your ductwork. Even though it may have the word “duct” in its name, duct tape is not effective for repairing faulty ductwork. What is effective is professional duct sealing. The process for professional duct sealing starts with a full inspection of your duct system so that the technician can assess the areas of damage. Once he/she determines what needs sealing, mastic, a fibrous adhesive, will be applied to the holes and cracks.

A piece of fiberglass or foil tape is placed on top of the mastic, and then the technician moves on to the next problem area so that the mastic can harden into a seal. For sectional disconnections, the technician will apply mastic to both ends of the ductwork, put the ends together and wrap them with metal binding, and then secure the metal binding with sheet metal nails; the mastic will harden and form a seal between the sections.

Benefits of Duct Sealing

  • Increased energy efficiency – air loss from faulty ductwork can account for up to 30% of your home’s total air loss. By sealing the faulty areas, you can regain and even increase the energy efficiency of your HVAC system.
  • Better indoor air quality – not only does air escape from faulty ductwork, contaminants, excess moisture, pollutants and excess dirt and dust do, too. Sealing the problem areas can put an end to these problems and greatly improve your indoor air quality.
  • Better comfort – when your ducts are properly sealed, the correct volume of air is delivered to your living spaces.

If you have faulty ductwork in your Phoenix home, call the experts who can seal your ductwork as needed: Johns Refrigeration.

Air Filters and Your Home

Tuesday, January 27th, 2015

John’s Refrigeration is changing the way you think about HVAC and your home. The system to heat and cool your home is really not about the unit outside – or as we like to call it, the box. The system includes the ductwork and air filter, which, when not properly sized and sealed, can cause dust, pollen, and other contaminants to enter your home, making the unit less efficient and you less comfortable.

How do air filters work?

The air that flows through your home goes through a filter before it enters the HVAC system, making it important to have the right size and kind of air filter. When the filter is clogged, the air in your home filters through those contaminants as well, blowing the dust and dirt back into your home.


A filter is important, not just to protect you from contaminants in the home, but to also protect your air conditioning and heating unit from damage. The Environmental Protection Agency (EPA) reports changing your home’s air filter as the most important part of maintaining your home and making the HVAC system efficient.

Sizing Air Filters and Ductwork

Filters that aren’t sized properly, including the newest on the market, can actually make your system less efficient by blocking airflow. This causes the entire system to work harder and use more energy. That translates into a higher utility bill for you.

The same holds true when ductwork isn’t sized and sealed properly. Your home breathes just like you do. When it’s not operating efficiently, it’s like it’s having an asthma attack; working harder for the same output.

The role of filtration is to protect the coil, not filter air around the house. In some cases, the solution for an asthmatic system is to use a basic (cheap) blue air filter that keeps the airflow at an efficient rate. Other solutions include having the ductwork evaluated to make sure it is sized and sealed properly so that dust and other contaminants are not entering the home.

Our team wants your home to be energy efficient and for you to feel comfortable. If you’re concerned about the efficiency of your home or aren’t as comfortable as you’d like it to be, Just Call John’s.

John’s Refrigeration Rave Review: Dust Allergy Solution

Tuesday, December 23rd, 2014

Dust Allergy Solution

Are you experiencing allergies or feel like your home’s air isn’t as clean as it could be? It’s time to Just Call John’s! Your home is a living being; inhaling and exhaling just like you do. When the ducts aren’t properly sized and sealed, the system has to work harder to heat and cool your home. It’s as if the home itself is having an asthma attack. The result is more dust and contaminants inside (instead of staying outside) and a temperature differential of more than a degree or two.

Our customer Joyce called us after hearing a rave review about John’s Refrigeration from her neighbor. She needed help with the amount of dust in her home and temperature differentials as much as five degrees on the east and west sides of her home. She has pets, but thought dusting once a day was excessive. And she was right.

We inspected the duct system and found the intake wasn’t sized properly and there were leaks. This meant dust was entering the home, along with air from the system, and airflow was inconsistent throughout the home. This created a need to clean the home frequently and be frustrated by varying temperatures within the home.

Solution and Results

We added a return, made a larger duct to the existing return, and sealed registers in an effort to keep dust, pollen, and other contaminants outside and the system running efficiently.

Joyce immediately noticed the quietness of the A/C when it was running. Over time, she also noticed less dust and has gone from dusting once a day to only twice a month! With just a few simple changes, we created more air flow, increased comfort, decreased the amount of dust, and make the system more efficient by properly sizing and sealing the ductwork.

Watch the video to hear how our work helped improve Joyce’s home:


Improving Indoor Air Quality with a New Unit

Wednesday, December 17th, 2014

There comes a time in the life of your HVAC unit that we have to recommend a new one. Don’t worry. We won’t surprise you. We will do everything we can with your existing unit in terms of maintenance and repair to keep it running efficiently as long as we can. The reality is that it’s a machine and machines wear out.

There is a good news. A new unit will improve indoor air quality.

  • New SEER ratings requirements effective January 1, 2015 make units more energy efficient than ever before. In addition to saving you money, the unit will also improve indoor air quality.
  • When you #JustCallJohns, you can expect that we will not only install the actual unit, but will also inspect and repair (if needed) the entire duct system of your home. It is estimated that as much as 20% of the air that moves through the duct system is lost to leaks and improper installation. We want to prevent leaks that cause pollen, dust, and other contaminants to enter your home.
  • Consider adding a humidifier to your air conditioning system to keep your home comfortable and your family healthy. When indoor air is too dry, it causes our mucous membranes to dry out and causes us to be unable to fight bacteria and viruses effectively. Very dry air can also exacerbate allergic reactions and chronic respiratory disorders like asthma.
  • Keeping a home sealed tightly can actually cause more problems than letting in some fresh air. The team at John’s Refrigeration will balance the air in your home to include some fresh air. They may also recommend a purification or air filtration system, especially if you’re prone to allergies and asthma. These systems will filter and prevent dust, pollen, and various allergens from getting and staying in your home.

A new unit is an investment in the health of you and your family that will not only keep you comfortable, but will improve indoor air quality. Contact us today to learn more.


Feel Better with a New Air Conditioner

Wednesday, December 10th, 2014

You’ve lasted another summer with your ages-old air conditioner, but you’re tired and want to feel better. You’re tired of the 100 degree days. You’re tired of being stressed about repair and utility bills. You’re tired of cleaning your home of dust that just won’t stay outside; it’s as if your air conditioning system is bringing all of it inside. Truth is, the amount of dust in your home may well be due to an outdated system and/or leaky ductwork.


At John’s Refrigeration, we do all that we can to repair and maintain air conditioners, but there comes a time when we just want you to feel better. If we’ve done all we can mechanically, we will recommend a new unit.

Less Stress. Stop worrying if your old air conditioner is going to break the bank and just get a new one! Older units can be repaired and maintained for a long(ish) period of time, but the fact of the matter is that it’s a machine. Machines get old and just weren’t made to be as energy efficient as newer models. The lack of efficiency is seen by you on that high utility bill that stresses you out on a monthly basis. Plus, we have a refund offer you can’t ignore!

Cleaner Home. Phoenix is a desert, making it the perfect place to live if you love to clean your home. And who likes to do that! Feel better when you’re spending less time dusting and vacuuming your home when you have a new air conditioner and air purifier. The air purifier will neutralize microbials at the source, keeping your home cleaner, smelling fresher, and less of a germ factory.

Improved Duct System. Not only will we install the new air conditioning unit, we will also check the duct system for leaks. Inefficiencies are often caused by poorly sized or leaky ductwork. We will recommend repairs as needed to make your home as energy efficient as possible.

If you’re done being stressed about your air conditioner, it’s time to Just Call John’s for a FREE ESTIMATE!

Reduce Indoor Dust and Five More Ways to Make Your Home Healthier

Wednesday, December 3rd, 2014

For about half the year, Phoenix, Arizona homes are closed to keep the air conditioning inside and the hot air outside. While this keeps us cool, it can also wreak havoc on allergies and asthma. Dust, pollen, and other contaminants can get into our homes through leaks in the duct system and unsealed doors and windows. Reduce indoor dust and you can reduce the allergies and asthma symptoms associated with unclean indoor air.


The team at John’s Refrigeration will come to your home and perform a whole home inspection to see where allergens are getting into your home and offer solutions such as a whole home air purifier, air humidifier, and sizing and sealing of the duct system.

Other ways to make your home healthier include:

  1. Carpets. Dust and other particles can get trapped in the carpets of your home, causing allergic and asthmatic reactions. The best option is to get rid of them and replace with tile or hardwood floors, especially in common areas. If you can’t do that, have carpets cleaned on a regular basis; every three to six months is ideal.
  2. Pets. If you have pets, you’re inviting allergens into your home. Dander, dirt, and dust can be causing breathing and other health problems. Before you decide Fido and Fifi have to be re-homed, try bathing them regularly and installing an air purifying system in your home that will trap dander and other allergens before they can make you sick.
  3. Shoes. Take your shoes off as soon as you enter your home. Ask guests to do the same. This will reduce indoor dust, bacteria, and environmental allergens that enter the home.
  4. Pests. No one wants to talk about unwanted house pests, but they are a reality, especially here in the desert. Wash your sheets and other bedding frequently and vacuum the bed to reduce the number of dust mites. If you see cockroaches, call an exterminator immediately. Cockroaches carry bacteria and disease and move as fast as three miles an hour, spreading germs throughout your home.
  5. Mold. Check under sinks and around windows for leaks that can eventually grow mold. As soon as you find mold, get rid of it, as it can cause a variety of breathing and other health problems.

If you’re worried about indoor dust and other allergens in your home, Just Call John’s for an inspection of your HVAC system including the unit and the duct system of the entire home. We’ll help you reduce indoor dust and keep you healthy!
