How Can UV Lights Help Your Home?

Monday, September 21st, 2015

UV stands for ultraviolet, the invisible wavelength of light that gives us a tan or a burn at the beach and makes our white clothes glow in the dark at rock concerts. But UV lights have a much more practical effect than that: helping to keep your home free from germs and illnesses. A UV light installed inside your home can stop germs and bacteria dead in their tracks, and help your family feel happier and healthier in the process. How can UV lights help you home? Read on for the specifics. (more…)

How Does Indoor Air Quality Affect Your Air Conditioner?

Monday, September 7th, 2015

Here in Mesa, AZ, temperature control takes top priority in terms of keeping our homes cool. A quality air conditioner can be your best friend when temperatures climb into the triple digits. But that’s not the only factor involved in household comfort: indoor air quality plays a huge part as well. In addition to helping your home feel fresher and less stagnant, indoor air quality can do wonders for helping your air conditioner cope with its workload better: reducing monthly costs as well as lowering the risks of a repair. How exactly does indoor air quality affect your air conditioner? We’ve included a brief breakdown below: (more…)

3 Types of Air Filtration Systems

Monday, August 10th, 2015

Mesa, AZ gets super-hot in the summertime, and most of us rightfully focus on our air conditioners to keep our homes comfortable. But frankly speaking, indoor air quality can be as much of a problem: anything from low humidity to the presence of germs and bacteria can lower the quality of your air and subsequently the quality of your life. You can fight it by installing an air filtration system in your home, which can address specific issues or a variety of them to help make the air fresher and healthier. But which one is right for you? You can answer that question with help from a professional technician, but here are 3 different types of air filtration systems to give you an idea of your options. (more…)

How Do Humidifiers Work?

Monday, July 13th, 2015

Mesa, AZ is a desert community, which means our air is very dry as well as being hot. Air conditioners can help address the temperature, but do very little to increase the humidity of the air. In fact, they can often do more harm than good in that department. As they cool the air, moisture condenses and becomes liquid (much like dew that forms in the early mornings). Your air conditioner safely collects the condensate in a pan and removes it from the system, but the effect is to make the dry air even drier. A whole-house humidifier can be the answer, and understanding how these systems work is key to explaining their benefits to you. (more…)

Why You Should be Concerned About Low Humidity

Wednesday, March 18th, 2015

There are lots of places in our country where excessive humidity is a big problem, but where we live, we can have the opposite problem: too little humidity. Humidity in a home needs to be balanced in order to be truly comfortable, and having too little humidity causes a number of problems.

The good news is that you can seamlessly add humidity to your home in Chandler with the installation of a whole-home humidifier. When you install a whole-home humidifier, it becomes a part of your entire HVAC system, so it’s important to hire an expert for installation, repair, maintenance or replacement. The technicians at Johns Refrigeration bring two generations’ worth of whole-home system experience to every job, so if you have concerns about your home’s humidity levels, call us today!

Effects of Low Humidity

Low humidity effects both people and your home in the following ways:

  • Dries out wood – most homes have a considerable amount of wood, from flooring to ceilings to furniture. When wood doesn’t have enough moisture it dries out, which leads to shrinking and eventually splintering. The end result can be irreversible damage.
  • Dries paint and wallpaper – paint can peel and bubble without enough moisture and wall paper can become unglued and start to tear.
  • Dries mucous membranes – too little humidity in your home can dry out your mucous membranes, which can lead to dry eyes, nose bleeds and dry skin.
  • Temperature discomfort – humidity holds heat, so if there is too little in your home, your air conditioning won’t feel as comfortable. As a result, you may set your thermostat lower than it has to be because even though the air is cool, it may not feel that way.

The EPA estimates that indoor humidity levels should range between 30%-60% at all times. When the level in your home sinks below 30%, you may see the above-listed problems ensue. A whole-home humidifier eliminates these problems by integrating directly into your existing HVAC system and supplying your home with the needed moisture to make it comfortable year-round.

If you are interested to see what a humidifier can do your for Chandler home, call the indoor air quality professionals at Johns Refrigeration today and schedule an appointment.

Asthma, Allergies, & Indoor Air Quality: Natural Allergy Remedies

Friday, October 18th, 2013

Allergy and asthma control begins where we spend 90% of our time: at home. Controlling the air quality in your home can naturally reduce allergy and asthma symptoms and decrease the triggers that cause flare-ups. Your home is the perfect place to start for natural allergy remedies.

Allergies don’t only cause sneezing and runny noses; they are also a main trigger for asthma attacks. You could have a chronic problem breathing well (easily, deeply) or coming down with respiratory issues. And it’s possible to develop asthma and allergies as an adult, even if you never had either as a child.

 

Although everyone is affected by it, people with asthma are more sensitive and experience the effects of poor indoor air quality more quickly and more severely. 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. The U.S. Environmental Protection Agency (EPA) states that asthma “is the leading chronic illness of children in the United States and the leading cause of school absenteeism due to chronic illness.”

The American Lung Association recommends source control as the first line of defense against indoor air pollution. Increasing the circulation of outdoor air into the home and reducing the humidity as much as possible helps because fresh air can also reduce the levels of indoor air pollutants. By reducing humidity, dust mite and mold growth decreases. Air conditioners help reduce the humidity and also prevent the exposure of outdoor allergens, 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 system maintenance. A clean and efficient HVAC system is an essential tool for natural allergy remedies to have in your family’s health tool box. John’s Refrigeration Heating and Cooling is authorized by both SRP and APS for duct testing and repair. We test your duct system to identify areas where the contaminants are getting into your home and will recommend actions you can take to keep your indoor air as safe as possible. We also sell and can install reusable electrostatic air filters, which attract and hold onto airborne particles like a magnet. The particles are only released when the filters are cleaned. This way, those particles stay in the filter instead of making their way into your lungs.

At John’s, we are your indoor comfort specialists and can address any issues with the air inside your home; making it easier to breathe easier.

Indoor Air Quality: Simple Ways to Make Your Home Healthier

Friday, September 13th, 2013

Did you know? The air in your home is dirtier than the air outside. This is due in part to the recommendations of the US government during and since the 1970’s energy crisis. At that time it was suggested that American homes be sealed as much as possible to prevent precious oil and electricity from being wasted. The result is that our homes aren’t breathing in a way that makes them healthy for us.

Our homes breathe? Yes, our homes have a life of their own. They take air in and out just as you do. When they are sealed tightly, the breathing is strained causing contaminants, dust and pollen to enter or stay in the home.  This creates poor indoor air quality and an unhealthy environment.

 

At John’s Refrigeration we believe in creating healthy homes which is why we offer the following simple ways to make your home healthier:

  1. Duct System: A properly sized and sealed duct system eliminates dust and contaminants as well as hot air from being brought into your home through the A/C system. The team at John’s Refrigeration can help you cut as much as 20% from your heating and cooling related energy costs by testing and repairing the duct system of your home. Once the duct system has been evaluated and renovated as needed to create an efficient system, we balance the pressure in the home.
  2. Balance Pressure: Your home is an extension of the duct system. Closing interior doors creates rooms that are not neutral pressure; they are positive or negative and affect the way the home breathes. Negative rooms, for example, become unsafe because contaminants like dust, pollen and carbon monoxide can be drawn into the home. Positive rooms push the cool (or warm) air out of the home. Whether positive or negative, it creates uneven temperatures throughout the house making it uncomfortable for you and your family.
  3. Fresh Air: Adding fresh air to the home creates a slightly positive pressure and keeps dust and other contaminants out of the home. Your home breathes and we don’t want it to be breathing hot, dirty, contaminated air from the walls or attic.
  4. Filtration: The final way to create a healthy home is to add a purification or filtration system to clean the air. The type of filtration system is up to the needs of the homeowner. A home with pets and/or more than two occupants would probably need a different system than a non-pet home with two or less occupants, for example.

At John’s Refrigeration we understand simple ways to make your home healthier. Concerned about the health of your home? Give us a call. We’re happy to help you.

Air Pollution Facts Phoenix: Summer v. Winter

Tuesday, September 10th, 2013

John’s knows the air pollution facts Phoenix!

Air pollution is caused by both human and natural sources. Human sources include vehicle emissions, agriculture, and industry. Natural sources include volcanic eruptions, emissions from vegetation, and dust storms, which are a big part of our monsoons here in the Phoenix area.

Air pollution is worse in the winter as opposed to the summer because of all the coal and wood burning used to heat our homes. During the winter, a layer of cooler air is trapped by a layer of warmer air above, forming a temperature inversion. An inversion traps pollutants close to the ground, increasing the chances for harmful particulates to reach unhealthy levels.

At night, the ground level temperature cools faster than the air above it, trapping pollutants under the layer of warm air. The warm air above the cooler air acts like a lid, trapping the cooler air at the Mediasurface, keeping pollutants near the ground, and leading to poor air quality. As the sun rises, the ground level temperature warms up faster than the air above it, pushing the air upwards, breaking up the warm air layer and allowing the pollutants to escape.

The strong inversion in winter confines pollutants to a shallow vertical layer, leading to high (poor) air quality levels. This is why “no-burn days” in the Valley of the Sun are issued: so the use of woodstoves and fireplaces don’t add to pollution conditions during the winter.

Outdoor air pollution contributes to indoor air quality, with both affecting our health. When your home is closed up – in summer as well as in winter – it can seal these pollutants in where you and your family spend most of your time. A clean HVAC system is crucial to your family’s health and the air quality inside your home. John’s Refrigeration Heating and Cooling can evaluate your duct system to determine if the bad air outside is entering your home and will recommend actions you can take to keep the air inside your house as clean as possible.

 

Let John’s help you clear the air.

Carbon Monoxide Symptoms and Prevention

Tuesday, September 3rd, 2013

Carbon monoxide (CO) is a deadly, colorless, odorless, poisonous gas. Every home can have CO: even an oven in the cleaning cycle produces CO, not just vehicles in an attached garage like many people think. The U.S. Consumer Product Safety Commission (CPSC) states that thousands become ill and about 170 people die every year in the US from CO produced by non-automotive consumer products.

The initial symptoms of low to moderate CO poisoning are similar to the flu and include headache, fatigue, shortness of breath, nausea, and dizziness. High level CO poisoning has more severe symptoms, including confusion, vomiting, loss of muscular coordination, loss of consciousness, and ultimately death. If you think you are experiencing any of the symptoms of CO poisoning, get outside to fresh air immediately and call the fire department from a neighbor’s home.

Be proactive about CO exposure in your home:

  • Don’t cover the bottom of natural gas or propane ovens with aluminum foil, which blocks the combustion air flow through the appliance and can produce CO.
  • During home renovations and repairs, make sure appliance vents and chimneys are not blocked by tarps or debris and that appliances are in proper working order when the work is complete.
  • Have your HVAC unit professionally inspected and serviced annually to ensure proper operation.
  • Install CO monitors in your home to detect the presence of this deadly gas.

John’s Refrigeration offers a professional grade, low level, carbon monoxide monitor, which continuously scans your home for CO. Our monitor detects CO levels as low as 5 parts per million (ppm), which is far below what monitors sold at the big box stores offer. Installed by our technicians, these monitors also have a digital display that shows any level of CO and include a two year warranty.

An example of a normal store-bought CO detector (reading zero) and the other one is our CO monitor which is picking up a reading. This family thought they had the flu.

The CPSC recommends that one CO monitor be installed in the hallway outside the bedrooms in each separate sleeping area of the home. Installing a CO alarm can provide some added protection, but is no substitute for proper use and upkeep of appliances that can produce CO.

Carbon monoxide kills – protect your family and call John’s Refrigeration Heating and Cooling; where you get a commitment, not just a response.

Reasons a Low Level Carbon Monoxide Detector is Important to Health

Wednesday, August 21st, 2013

The biggest reason a low level carbon monoxide (CO) monitor is important to health is that CO is the #1 cause of poisonings around the world. At John’s Refrigeration we help our customers create healthy home environment which is why we want you to understand the importance of installing a low level CO monitor. Understanding the causes, symptoms and prevention of CO poisoning keeps your family healthier and can even save lives.

Carbon monoxide enters the home in different ways. Sources include water heater, gas range, space heaters, negative pressure in the home and from vehicles in your attached garage. Because these are all common in the home, we suggest monitoring the levels of CO in your home.

Most CO monitors don’t alarm until the CO level reaches 70 parts per million (PPM) for more than three hours. OSHA and the World Health Organization’s guidelines are 15-35 ppm. That leaves a lot of time for your family’s health to be compromised.

Poisoning from carbon monoxide (CO) is often initially misdiagnosed as the flu. When CO enters the bloodstream it prevents oxygen from reaching vital organs including the heart and brain. Symptoms include dizziness, headache, GI issues and other flu-like symptoms. The interesting part is that symptoms are less severe when you are away from a home or building with higher levels of CO; that’s not common with the flu or other non-CO poisoning illnesses.

 

Preventing CO poisoning includes the following steps:

  1. Testing CO levels in your home by a professional HVAC installer.
  2. Annual inspection and servicing of HVAC systems. We offer preventative maintenance packages to all new and existing customers. Visit http://www.johnsrefrigeration.com/service for additional information.
  3. Never use a charcoal grill or portable generator in an enclosed space like a home, garage or shed.
  4. Never use a gas stove or oven to heat your home.
  5. Install low level carbon monoxide detector in your home. We can help you find one.
  6. Understand the symptoms of CO poisoning including headache, dizziness, weakness, nausea and vomiting. Leave the home and get to a hospital for treatment.
