What's That Brown Cloud on the Horizon? How to Improve Your Indoor Air Quality

Wednesday, January 13th, 2016

Living in the desert, Arizona homes can experience higher levels of dust and other contaminants than homes in other climates. As a result, it's important to consider your home's indoor air quality and learn what you can do to ensure a healthy environment for your family.

Those who suffer from allergies can be especially susceptible to issues from poor air quality in the home. Other signs your home may have poor indoor air quality include:

  • Persistent headaches
  • Dizziness
  • Weakness or fatigue
  • Nausea

Many symptoms resulting from issues with indoor air quality appear similar to the flu and often go undiagnosed.

To help improve your indoor air quality, start by contacting John's Refrigeration to learn about our air quality services. There are a number of simple steps to take to help insure healthier indoor air quality:

  • Check the duct system: Air contaminants like dust, pollen, and other environmental toxins can get into your home and circulate through dirty, leaky ducts. Getting ducts cleaned, checked for leaks, and repaired is a valuable first step for protecting the air you breathe.
  • Install an air filter: After checking and sealing the duct system, John's can install our Fresh Air Filter System that will help continue to keep the home ventilated with clean air. Air filters catch pollutants before they enter the indoor air.
  • Beware of carbon monoxide: Carbon Monoxide is an odorless but poisonous gas that can come from your heater, furnace, fireplace, or other gas appliances and tools. Undetected, it can cause a number of health issues and can be fatal. When we conduct a heating repair service, we check for things like cracks in the heater, where carbon monoxide can leak.
  • Add a humidifier: Our dry climate leaves the indoor air lacking moisture, causing skin issues, potential respiratory problems, and increased dust. Adding a humidifier to the system can help alleviate these issues and allow homeowners to manage the humidity levels in the home.

To schedule an inspection to check on the quality of your indoor air, contact John's Refrigeration at (480) 718-1172.

The Principles of Good Duct Design

Tuesday, July 21st, 2015

According to the U.S. Department of Energy, poorly designed air duct systems can lose as much as 40% of the heating or cooling energy passing through them. A poorly designed air duct system makes it impossible for an HVAC system to run at its optimal efficiency. HVAC systems are responsible for almost 50% of the energy expenses in a typical home, and the ductwork plays a significant role.

The design and efficiency of your home's ductwork contributes to utility bills, air quality, and comfort, as well as efficiency and wear on the system. Ductwork provides the channel through which cooled and heated air travel. Restricting that air flow because of poor duct design is detrimental in so many ways.

Good duct design increases the efficiency of air flow, making it easier for your HVAC unit to cool down or heat up your home so you're more comfortable. Sometimes ductwork is located in places where the air contains pollutants like dust and mold. If ductwork isn't sealed well, those pollutants may be sucked into leaky ducts and delivered throughout the house. Since air leaks are one of the main cause of energy loss in ductwork, making sure all air ducts are well sealed and connected properly is important.

Leaks in ductwork provide a way for dust, allergens, debris, and pests to get into the ductwork. This will negatively affect indoor air quality and can cause airflow obstructions that contribute to energy loss, making your utility bills climb. Restricted air ducts will also add to the wear and tear on your HVAC equipment.

Just Call John's and schedule an appointment to have your ducts inspected by one of our NATE Certified technicians as part of your annual HVAC maintenance so they remain clean, sealed, and insulated for optimal efficiency. John's offers air duct inspections and cleaningso you can be comfortable all year round. We also offer our Peak Performance Club so you can rest assured that your a/c unit won't konk out in the middle of summer.

Air Ducts

Tuesday, July 14th, 2015

Our homes breathe, believe it or not. And our HVAC systems help control that process. How do air ducts figure into this equation, though?

Dirty air ducts cause the HVAC equipment to work harder and less efficiently. Having your ductwork inspected can mean you'll have improvement in air quality and less dust inside your home. Clean air ducts help the entire HVAC system worked more efficiently. A full cleaning of the air ducts in your home can yield long-term energy savings, but hiring certified professionals to do the job is vital. In fact, a poor cleaning job is worse than no cleaning at all, as it can kick up harmful particles or even break portions of the HVAC system.

Air duct cleaning should involve a thorough cleaning of the air handler, registers, grilles, fans, motors, housings, and coils of the HVAC system, not just the ductwork. John's NATE Certified technicians will also perform an inspection of the ductwork and let you know if there are any problems that need to be addressed.

If you're not sure if you need to have your air ducts cleaned or inspected, here are some key questions to ask yourself:

  • Have you renovated your home in the past few years? Ducts should be sealed off during remodeling projects, so if they weren't, dust and debris may have become lodged inside the ductwork. Or the air ducts could have been moved, causing them to leak airflow.
  • Could there be animals in your air ducts? There may be evidence of animal infestation or nesting in your air ducts or HVAC system, which can greatly affect the air quality in your home. Whether those animals are living in your ductwork or have died, they don't belong there.
  • Do you see mold on your vents? If there is visible mold growth on your vents or inside the ductwork, the air quality in your home has been compromised and is likely affecting the respiratory health of everyone who breathes the air in your home.
  • Have you noticed pet hair, odors, or dust being released into the room through the vents? Once again, these are signs that your air ducts need to be inspected and possibly cleaned.
  • Does anyone in your family suffer from allergy or other respiratory-related illnesses? If so, you may want to consider having your air ducts cleaned to see if the HVAC system is the reason.

People often report using their air conditioner less in the summer after having their air ducts cleaned because of the improved airflow. That means less money paid to the utility company and more money in your wallet. Plus, your family will be more comfortable and breathe easier. Just Call John's to see how we can help you with air duct inspections and cleaning.

3 Tips to Help Save on Air Conditioning Bills This Summer

Monday, May 4th, 2015

Few locations in the country need air conditioning as much as the Valley of the Sun in Arizona. During the summer we can expect to have our ACs running on a regular basis throughout the day and sometimes into the evening. Any average summer can end up creating very steep utility bills from air conditioning alone.


How Duct Sealing can improve Your Air Conditioning

Monday, 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.

Airborne Contaminants and What to Do About Them

Tuesday, 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.

How Duct Sealing can Improve Your Quality of Life

Friday, February 20th, 2015

When a heating or air conditioning system develops a problem, you usually notice it right away.

Weird sounds start coming from the unit, efficiency decreases, something starts smoking or icing over, etc. etc. Unfortunately, that isn't the case with ducts. Duct issues are silent, subtle, and often go completely unnoticed by the homeowner. That doesn't make them trivial, however. Let's take a look at one of the biggest problems that ducts are afflicted with, and how duct sealing can solve it.

Duct Leaks

Ductwork is really susceptible to leaks, and the sad fact of the matter is there isn't much to be done to prevent them. Most ducts are installed poorly, leaving gaps between the sections. Even properly installed ducts can work themselves loose through normal operation, expanding and contracting over time. In humid environments, there's the added problem of moisture causing corrosion and opening holes in the ducts. To make matters worse, even small duct leaks can really add up.

The US Department of Energy has estimated that the average home heating system loses as much as 30% of its output to leaks in the ductwork. Nearly a third of your heating or air conditioning output could be wasted before it gets to its destination, and you very likely wouldn't even realize that it's happening.

Duct Sealing

In an effort to address the massive issue that duct leaks present, duct sealing has become a common service. Basically, duct sealing consists of finding and closing any leaks that are present to improve energy efficiency. The HVAC technician conducting the service uses a number of specialized tools to address any possible kind of duct leak. While some homeowners may attempt to seal their own ducts, they often lack the materials and expertise to do the job properly. Duct sealing can also improve your air quality by preventing moisture from entering your ducts and causing mold growth. You should have your ducts sealed at least once every two years, in order to prevent wasted energy.

If you haven't had your ducts sealed in a while, call Johns Refrigeration. We provide ductwork sealing services throughout Chandler, AZ.

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.
