3 Tips to Size and Seal Your Duct System Properly

Thursday, October 23rd, 2014

While the actual HVAC unit is important to keeping your home comfortable during the hottest and coldest months of the year, the duct system plays a key role in keeping you comfortable and healthy. If it isn’t sized properly, it can cause dust and contaminants to enter your home, hot air to be brought into your home through the A/C system, and increased energy bills.

Do you need to size and seal your duct system properly?

Your home may have ducts that are not properly installed if you experience:

  • Extremely high energy bills during the hottest or coldest months.
  • Rooms that are stuffy or difficult to keep cool or warm.
  • Excessive dust and unpleasant odors.

Test the System. The team at John’s Refrigeration can evaluate and renovate the duct system of your home, solving these problems:

  1. Size Matters. Your home breathes just as we breathe. When the ducts are too small for the HVAC system that is installed, it causes the air to be constricted and the system to work harder to heat and cool your home. We will examine every part of the duct system for leaks, blockages, and poor design.

TIP: Use the proper size air filter for your system and change the filter as directed; typically once a month. Improperly sized or dirty filters constrict the flow of air as much as an improperly sized duct system.

  1. Air Quality Matters. The key to healthy indoor air quality is having a certain amount of fresh air in the home. We can test indoor air quality and fix issues you may have, including helping fresh air flow properly through the system and into individual rooms.
  2. Hole-y Matters. In the typical home, about 20% of the air that moves through the duct system is lost due to leaks, holes, and poorly connected ducts. Leaks cause the system to work inefficiently, costing you in utility bills. We can repair the leaks and fix breaks and get your money back in your pocket.

The team at John’s Refrigeration can size and seal your duct system properly, keeping air flowing, contaminants and dust outside the home, and you comfortable. Schedule an appointment today!

Will a new air conditioner improve indoor air quality?

Thursday, September 11th, 2014

When you ask an Arizona resident what makes them least satisfied, some might say traffic. Others will say all of the chain stores and restaurants. Most of the people we ask tell us they are least satisfied with indoor air quality. This is due in part to the quality of outdoor air, but not completely. (more…)

Have a cleaner home with an air conditioning install

Tuesday, July 8th, 2014

You come home from a day of work and your house is warm.

You turn the thermostat down, but it’s just not cool enough.

It’s the summer and you’re feeling the heat in your own home.

At John’s Refrigeration, we believe in helping our customers maintain a comfortable home at an affordable price. We offer our Peak Performance Club to maintain the health of your air conditioning system through the hot Arizona summers. For as much maintenance as we can do, there will come a time when you will need a new unit.

While an air conditioning install is a big cost, there is one big advantage – a cleaner home!

A new air conditioning unit brings a cooler, quieter, more energy efficient home.

There’s no need to worry if your home is cool when you get home from a long day.

There’s no need to constantly turn the thermostat down to keep the house comfortable.

And most importantly, an efficient system means less housework.

When the team at John’s Refrigeration installs a new air conditioner, we check the entire system to be sure it is running at top efficiency. This includes checking the ductwork for leaks, installing the proper size ducts and air returns, and making sure the air filter is the right size for the unit. It’s how we help our customers stay cool through the hot summer.

When your home is sealed properly after an air conditioning install, you can rest assured the air in your home is healthy. You will have to clean less because dust, pollen, and contaminants are outside the home where they belong. This means less dusting and vacuuming and more time to spend with family and friends. To learn more, please contact us today.

Why Indoor Air Quality Testing is Important

Sunday, May 18th, 2014

As much as 90% of our time is spent indoors, making it especially important to understand indoor air quality. Do you notice you sneeze more or have headaches when you’re at home and the symptoms clear up when you leave? That’s a sign that there is an air quality problem in your home. Consider getting indoor air quality testing to identify exactly where the problems are so you can find solutions and start feeling better.


What is indoor air quality testing?

Indoor air quality testing measures a variety of factors that contribute to how you feel when you are in your home or office. These include the temperature, humidity, lack of ventilation, mold from water damage, or exposure to other chemicals.

Signs the air quality in your home is a problem

  • You feel better when you’re away from home
  • There is dirt or dust around vents
  • Air smells stale, as if it isn’t circulating
  • Changes to your health after a home renovation
  • Mold in the home
  • There is no outside air circulating in your home

Indoor Air Quality Solutions

Oftentimes people think a tightly sealed home will keep pollutants outside. While that is true, they fail to recognize that the air in the home will be sealed inside, allowing no fresh air from outdoors into the home. While outdoor air contains its fair share of pollutants, it is important to circulate the air in your home. When the air is not circulated, it can cause a variety of breathing, allergy, and other health problems.

We recommend installing a home air cleaner, which is installed in the ductwork of the home, keeping the air clean for you and your family. Whole-home air filtration systems remove particulates such as dust, pollen, smoke, animal dander, and tobacco smoke so you’re breathing the cleanest air possible in your home.

At John’s Refrigeration we are dedicated to keeping you and your family comfortable and healthy in your home. Contact us to today to get an indoor air quality test.

Wind and your HVAC System

Tuesday, May 13th, 2014

Monsoon is not the only time the wind blows here in the Valley of the Sun.  Sometimes the wind kicks up and dust devils toss not only dirt and debris, but other pollutants, into the air. Where there are strong winds, there is blowing dust when you live in the desert. The dust creates a thick haze, affecting visibility while driving. Not only do high winds and dust make it difficult to drive, but they also make it difficult to breathe if you have respiratory issues like asthma or allergies.

Here are a few tips to help you get through these windy days and still be comfortable:

  • Since a home’s a/c unit filters the outside air, dust storms can strain it, making your system work harder and less efficiently. Learn more about how winds and monsoon affect your home’s ability to keep pollutants out of your home by reading “Monsoon”.
  • Because the EPA ranks indoor air pollution as the fourth largest environmental threat to our country, it’s imperative to keep the air we breathe while inside our homes as fresh as possible. An efficient HVAC unit can provide that. Read more about how to prevent dirt and dust from invading your home at “Indoor Air Quality.”
  • Pollen is the most difficult allergen to avoid and it’s almost impossible to do so when the wind starts blowing. Learn how, with proper air balancing, duct sealing, and using the correct filter, you can prevent pollen and other allergens from getting in your house at “Pollen and your HVAC system.
  • Pollutants increase the chance of upper respiratory infections and cause adults to miss work, children to miss school, and often require multiple visits to doctors’ offices and sometimes even the emergency room. “Asthma, Allergies, & Indoor Air Quality” discusses this topic in more detail.
  • Your heating and air conditioning system can either be contributing to asthma symptoms or causing asthma attacks by harboring and spreading pollen and other allergens. “HVAC and Asthma” mentions how a properly functioning HVAC system can help reduce indoor allergens in part by maintaining a consistent indoor environment free from external, airborne irritants.
  • Air filters are vital at keeping pollutants from infiltrating your home. Wind picks up dust and that dust makes it into your home if you have a dirty air filter. Read what else a clean air filter can do for your family’s health in our upcoming article, “The Importance of Changing Your Filter Regularly”.
  • Cleaning the air in your home so that your family is able to breathe easier is a priority at John’s. We install home air cleaners that will help you breathe easier and we talk about them in “What is a Home Air Cleaner.”
  • Whole-home air filtration systems make the air in your home as clean as possible by removing annoying particulates and allowing you to breathe cleaner, healthier air. Not only will your health improve with this system, but a significant energy savings can also be realized. To answer the question, “Do You Need A Home Air Filtration System?” read our blog.

John’s Refrigeration Heating and Cooling takes the way you breathe while inside your home seriously. If spring winds, monsoon, dust, pollen, and other irritating pollutants are interfering with your health, just call John’s.

Why is it important to regularly change air filters for home?

Thursday, May 1st, 2014

All of the air that flows from your HVAC unit into the living spaces of your home must pass through an air filter before it gets to the air conditioning or heating unit. If the filter is clogged with contaminants, the air will filter through those pollutants as well. Air filters for home don’t just help improve the air quality inside your home, however; they also protect your heating and cooling system from being damaged. The Environmental Protection Agency cites changing your home’s air filter as the most important maintenance task that you can do to optimize your HVAC system’s energy efficiency.

By changing the air filter in your home, you’re not just allowing the unit to breathe easier; you are also doing the same for your family.


There are a host of health problems that can occur as a result of airborne contaminants inside your home. Change your air filters on a regular basis to keep your home comfortable and to avoid the many respiratory difficulties, allergies, and illnesses that can occur because of the circulation of bad air in your home.

Most air filters trap contaminants including dust mites, tobacco, bacteria, dust, pet dander, pollen particles, and particles that carry viruses, which can help keep your family healthier, too. The amount of contaminants captured by the air filter increases over time and it will eventually become so dirty that it will restrict airflow. The HVAC system is then forced to work harder to move the amount of air necessary to maintain the desired temperature in your home. The amount of additional energy your unit has to draw under these conditions is significant and often results in higher utility bills.

Buying the correct size filter is also important; you want the air to move through the filter, not around it. Please read our article on what type(s) of filters to use. Change the air filter on a regular basis in order to keep your unit working as efficiently as possible. Air filters should be replaced (or at least checked) every month, especially in the winter and summer when your system is used the most.

In order to get the most efficient use of your system, change your air filters regularly in order to enjoy the coolness of your home when temperatures reach 110°. It’s the easiest, yet most important way to keep your HVAC unit running efficiently and keep it running when you need it.


Xeriscaping and Allergies

Thursday, April 10th, 2014

Xeriscaping refers to landscaping in ways that reduce or eliminate the need for additional watering. Xeriscaping uses native plants, which often have a low pollen count and will cause less trouble with allergies. So, not only does xeriscaping save water, but it can also reduce the allergens that are around your home, making it easier for you to breathe.


Xerogardening, another form of xeriscaping, involves planting a “low allergy garden” by establishing plants and flowers that are pollinated by insects, rather than those pollinated by the wind. A Xerogarden can also be an effective way of reducing dust in the garden and in your home’s landscaping. Both utilize water-wise or drought-resistant plants that are native to the area. You can even design your xeriscape or xerogarden as a lure for local wildlife, including hummingbirds and quail.

Another way to decrease the amount of pollen and other allergens from around your home would be by using ground covers in your landscaping. The ground covers, sometimes gravel, but also low, creeping plants, cover the soil to reduce the amount of dust that’s carried by the wind. Dust that ends up in your house, which can make it difficult for you to breathe.

Controlling the air quality in your home can reduce allergy and asthma symptoms and decrease the triggers that cause flare-ups. Air conditioners help reduce the humidity and also prevent outdoor allergens from entering the home, as long as the units are routinely serviced and running correctly. Most health risks associated with poor indoor air quality can be minimized with proper HVAC system maintenance.

At John’s, we offer several suggestions for homeowners to improve the quality of air in their homes, including something as simple as replacing inefficient air filters. To find out if your home could benefit from installing an air filtration system to help control allergens in your home, read our blog, Do You Need A Home Air Filtration System?

Causes of Duct Cleaning Calls in Mesa

Wednesday, March 5th, 2014

For the cleanliness of your home, efficiency of your heating and cooling system, and quality of your indoor air, you need to have a clean ductwork system. Contamination inside ducts can consist of dust, dirt, debris from construction, dander, pollen, hair, mold, and mildew. Removal such a variety of pollutants requires more than a long-handled broom and a bottle of cleaner. Duct cleaning requires special training and professional equipment. When you need duct cleaning in Mesa, AZ, call Johns Refrigeration and talk to our air quality specialists today.

You should schedule duct cleaning every one or two years, depending on how rapidly build-up develops inside your ventilation system. Here are some causes for contamination to begin to accumulate and lead to the need for duct cleaning.

  • Ductwork breaks and gaps: Dust will gradually begin to build up inside ducts, but it can take over a year for this to become thick enough that it will cause trouble. But if your ducts have breaks in them from corrosion, damage, or poor sealing due to improper installation, dust and other outside debris will rapidly start to infiltrate the ventilation system. Not only will you need to schedule cleaning, you will also need repairs to seal the breaks.
  • Clogged air filters: Neglecting to regularly change the air filters in the ventilation system will cause the filter to clog and dust to begin to get through. The air filter should be changed once a month during periods when your HVAC system is working regularly.
  • Time: You simply can’t avoid some debris entering the ventilation system, and because the ducts are sealed along their length to maintain air pressure, this contamination will continue to grow over time. According to the NADCA (National Air Duct Cleaners Association), in a typical six-room home, up to 40 pounds of dust is created each year through everyday living, and this contaminated air circulates through your home 5 to 7 times a day. No matter how clean your home, no matter how strong your ducts, contamination will get inside it and eventually require cleaning.

If you’ve never had your ducts cleaned before, you should schedule it right away. Find out from your professional cleaning technicians how often you should have the service in the future, since they will have a solid idea of how much contamination your ducts will gather each year. Get into a habit of regular duct cleaning visits: you deserve to have the healthiest air in your home.

Johns Refrigeration has the Mesa, AZ duct cleaning team that can take care of you.

Nosebleeds and Your HVAC Unit

Saturday, March 1st, 2014

If you’ve ever wondered if there is a connection between your HVAC system and having a bloody nose, wonder no more.  Our Arizona desert is well known for its lack of humidity, but if our homes aren’t properly ventilated, the air inside can be just as bad, if not worse, than the air outside. Poor indoor air quality and low humidity can cause or contribute to the development of dry and cracked skin, respiratory infections, asthma, and nosebleeds.


Controlling these health problems before they start, with humidifiers and clean indoor air, as well as appropriate ventilation with clean, fresh air, can reduce the number of nosebleeds you or family members experience. Mucous membranes in the nose and throat dry out, making you more susceptible to colds and respiratory illnesses. Adding humidity to a dry house or balancing the amount of humidity in your home can reduce nosebleeds and other, more serious health problems.

If your HVAC unit is running efficiently, it works to create an environment that keeps the air inside your home healthier and cleaner. A properly functioning HVAC system can help reduce indoor allergens that irritate your nose and throat in part by maintaining a consistent indoor environment free from external, airborne irritants.

A whole house Humidification System can help increase the comfort of your home and allow you to breathe easier once John’s identifies any air quality problems inside your home and resolves them. Between proper air balancing, duct sealing, using the correct filter, and making sure humidity levels are healthy, you can prevent pollen and other allergens from getting in your house, significantly reducing allergies and asthma symptoms.

John’s Refrigeration will improve the air quality in your home by taking a holistic approach because we understand how your home, duct system, and A/C system work together to improve your health. Stop nosebleeds before they start and Just call John’s.
