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.

Ductless Air Conditioning

Tuesday, July 28th, 2015

Ductless air conditioning involves the installation of an outdoor and indoor unit, similar to a central air conditioner system. But where central air conditioning uses a fan to distribute air through the ducts, ductless systems contain all of the indoor components in an air handler mounted high on the wall or on the ceiling. These air handlers blow cool air directly into the room, which is why most homes require more than one air handler. One outdoor condenser unit can usually accommodate up to four indoor air handlers, though. However, you don't necessarily need ductless air conditioning to fix a hot room. Your current ductwork may just need to be repaired or cleaned, which is also a service that John's offers.

If you choose ductless air conditioning, these units deliver cooling evenly throughout your home without having any ductwork. Ductless units are often just as powerful as central a/c systems. In fact, many traditional HVAC systems that use air ducts can't perform as well due to leaks in the ductwork. With a ductless unit, you won't have to worry about air leaks, which means you'll be more comfortable and enjoy lower utility bills because of the energy savings.

When you use ductless air conditioning to cool your entire home, you also have zone control, which isn't an option with a ducted system. Each air handler has its own thermostat, which means that you get to choose the temperature in any zone of the house separately from the other areas. So if you need the bedrooms to be cooler at night, but the kitchen and living areas to be cooler during the daytime, all you have to do is adjust the temperature in those zones.

If you'd like to learn more about ductless air conditioning, Just Call John's. We offer ductless service, as well as duct repair and inspection for homes that have ductwork.

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.

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.
