How to get rid of dust

Wednesday, January 20th, 2016

Every home carries dust, but how much dust lives in your home depends on a number of factors, such as the climate you live in, if you have pets, smoke cigarettes, or even cook certain types of foods. In addition to being a sight for sore eyes and often a trigger for allergy sufferers, dust can contain toxic chemicals.

Living in Arizona, we're no strangers to dust and it's not just something that affects air quality during monsoon. During winter in the Phoenix metro area, a layer of cooler air becomes trapped by a layer of warmer air just above it, forming what's called an inversion. An inversion traps pollutants from all kinds of sources and this increases the chances of carbon monoxide. That is why it's necessary to take care of the system that circulates the air in your house on a regular basis to prevent these toxins from getting into your home.

Here's our list of effectively and safely:

  • Fit your air conditioning system with high quality filters and change them frequently to make sure they're doing their job. At John's Refrigeration our air cleaner installation experts can work with you to make sure that the air quality in your home is safe. We also take care to ensure the new filter in your home doesn't impede the balance of air pressure in your home or reduce the efficiency of your system.
  • Caulk cracks and crevices to prevent dust from getting into those hard to reach areas.
  • Vacuum frequently, using one with a HEPA (High Efficiency Particulate Air) filter. If you are prone to allergies or suffer from asthma, you may want to consider investing in a vacuum that has high suction and high dust removal capability. Make sure to clean out and replace the filter regularly.
  • Clean with microfiber cloths; their smaller fibers cling to the dust particles. Avoid synthetic sprayers and wipes, as they only add unwanted chemicals to the air.
  • Mop uncarpeted floors regularly with water and the manufacturer's recommended cleaning products.

If your home has an excessive amount of dust and you're worried about the toxins your family is breathing in, call John's today to schedule a peak performance home evaluation. We will be able to look at not only your air conditioning and heating system, but also the way you live in your home and then offer recommendations to keep the air in your home dust free and clean.

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.

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.

Is replacing your windows worth it?

Tuesday, June 23rd, 2015

When it comes to keeping your home cool, maintaining your home's HVAC unit is key. An efficient unit will not only help keep your home cool and comfortable, but it can also help keep the dust out of your home, which means your home will be cleaner. Less dust also is directly related to fewer respiratory illnesses like asthma, but also annoying conditions like dry skin and bloody noses. For a/c savings, though, can replacing your windows also save you big bucks?

Most windows can actually be compared to having a giant hole in your home's insulation. Especially if they are older, drafty windows. But new windows are expensive and installing them often costs just as much as the windows themselves. New windows aren't the best cure for reducing your utility bills. There are easier and cheaper projects you can do, such as sealing all your home's air leaks, which will have a bigger impact.

The energy savings from new windows don't usually come even close to justifying their cost. And research shows that the payback period for replacement windows can be as high as 100 years. The new high-efficiency windows might offer twice the insulation value as the old single-pane windows you currently have. Which means new windows would cut your energy loss through the windows by as much as 50%. But some studies reveal only about 30% of your house's heating and air conditioning disappears out the windows.

Before deciding to replace your windows for a/c savings, Just Call John's to see what we can do to help you reduce your utility bills. John's doesn't just repair and replace HVAC units, we also offer a service that replaces the screens on your windows. We have thermostats that you can control even when you're not at home. Check out one of our recent appearances on Sonoran Living Live where owner Andrew John talks about some of the options available for a/c savings.

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 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.

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.

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!

Should we try what China is doing by fighting pollution?

Wednesday, November 26th, 2014

It has recently been reported that China has designs for towers that will filter air and water in highly populated and polluted cities. At the base of the towers are greenhouses that could, at least in theory, grow vegetation, including fruits and vegetables, throughout the year. It sounds good in theory, but should we try what China is trying by fighting pollution?

Maybe. Maybe not.

At this point, it's just theory and a set of drawings. We, including China, don't know if the tower will be worth the resources spent to create it. Resources that include the environment.

In order to make space for new towns and suburbs, engineers are suggesting that the tops of mountains would need to be sliced off in order to fill the valleys caused by the construction of the immense towers. That in and of itself has environmental implications beyond fighting pollution, including what would happen to the wildlife and ecosystem of these mountainous areas.

But…

China's air pollution is reportedly so bad that it is often compared to a nuclear winter. Crops are damaged and there is a real threat to their food supply. They, rather than the U.S., might be more likely to build the air and water filter towers.

Should we try what China is trying by fighting pollution?

Let's look at the viability of creating a monstrous tower. In densely populated cities like New York, Chicago, or Los Angeles, we would have to destroy private and public land to even have space for this type of tower. That alone would have environmental and political implications.

While there are places in the U.S. with poor air quality, no area comes close to a nuclear winter. So is it worth it – even if we can scrub our air and water clean – to build such a tower?

Maybe. Maybe not.

We're not a government-controlled nation (like China) that can make blanket decisions for the people. The reality is that between politicians, businesses, and environmentalists, an air and water filtering tower is probably never going to happen.

And China hasn't even built one yet so we don't have a real case study to review.

Until someone else builds it, we don't think it's happening here. No matter how good it sounds in theory.
