Importance of Clean Air Filters

Tuesday, May 26th, 2015

With summer quickly approaching, many of us have already started using our air conditioners. If we haven’t yet, we will be soon. Higher temperatures bring higher utility bills. A very easy way to help keep cooling costs down is to regularly replace or clean your a/c unit’s air filter.

The importance of clean air filters cannot be overstated. Your house needs to be able to breathe in order for the HVAC unit to work efficiently. If the air filter is clogged with dust and other pollutants from your home’s inside air, then your a/c unit is working harder to do its job. Changing your air filter every month is an easy way to keep your unit running the way it’s supposed to. Remembering to replace the air filter, though, can sometimes be a challenge. If you change out the filter when your utility bill comes in the mailbox, that’s an easy way to remember, and it’s more likely to get done.

If you have an electrostatic air filter, then you don’t need to replace it every month; you just need to clean it. Electrostatic air filters create their own electrostatic charge, attracting more particles than traditional, disposable filters, and they are 10 times more efficient than disposable filters. Electrostatic air filters are permanent, washable, and designed with a heavy duty aluminum frame, with two layers of a special polypropylene weave on the front and back, and they contain a unique poly internal lining.

Since these permanent filters clean the air by using static electricity, airborne particles are attracted and held by the static charge until they are released by washing. In order to clean them, simply flush with water in the opposite direction of the air flow arrows, then rinse the other side, drain the excess water, let air dry, and reinstall.

John’s offers a filter service where we bring out a year’s worth of filters so you don’t have to remember to buy them. We also sell electrostatic air filters and can show you how to install and clean them.

Keeping filters clean extends the life of you’re a/c system and helps reduce costs. To find out how John’s can help you with your cooling needs, Just Call John’s.

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.


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.

What is a radiant barrier and is it worth the cost to install in your home?

Wednesday, November 12th, 2014

The Department of Energy describes a radiant barrier as a highly reflective material that reflects radiant heat rather than absorbing it. It is installed in homes, usually attics, to reduce summer heat gain and reduce cooling costs.


Sounds great, especially for the Arizona summer, at least in theory. Before you’re sold on the idea, let’s look at whether or not a radiant barrier is worth the cost.

  1. The easiest homes to install radiant barriers are new builds. In an existing home, it is best to install in an open attic.
  2. As with A/C units, the efficiency is dependent on the installation. While you can install yourself, we recommend hiring a RIMA International certified installer who understands which type of barrier is best for your home and the proper place for installation.
  3. Choose the type of barrier that is most appropriate for your climate and home. Radiant barriers are available in reflective foil, reflective laminated roof sheathing, and metal roof shingles. In Arizona, it is recommended that you use reflective foil.
  4. Location of the barrier is as important as the type of barrier you select. Simply laying a foil barrier on the attic floor will not be effective as it will gather dust, dirt, and other contaminants quickly.
  5. Other factors to consider are the cost of hiring a contractor for installation, the size of your house, and how accessible the attic is.

As with any home improvement project, it is important to ask a lot of questions of professionals as well as from your neighbors and friends. You also want to research the options yourself so you’re an informed consumer.

Energy Efficiency – Will this DOE change matter?

Wednesday, November 5th, 2014

In an effort to continue making American homes more energy efficient, the U.S. Department of Energy (DOE) is increasing the minimum federal standard for air conditioners in the southern United States, including Arizona, from SEER 13 to SEER 14 effective 1/1/2015.


At John’s Refrigeration, we are dedicated to keeping our customers safe and comfortable and will, of course, comply with these changes. We also believe that the energy efficiency of your home depends on much more than the SEER rating of your AC unit.

Let’s start by defining Seasonal Energy Efficiency Ration (SEER)

Seasonal Energy Efficiency Ratio (SEER) is the total cooling output (in British Thermal Units or BTUs) provided by the unit during its normal usage period divided by its total energy input (in watt hours) during the same period. The higher the SEER rating, the more efficient the unit. In theory, the SEER 14 is a more efficient unit than the SEER 13.

The SEER Challenge

The rating is derived in a laboratory setting with a steady temperature of 85 degrees, well below temperatures we see here in Arizona. In addition to the temperature, the testing room has perfectly installed ductwork. In other words, it’s a closely controlled environment that represents almost no home in America or anywhere else.

The Solution

While we believe the SEER 14 units will provide greater energy efficiency, our team of certified and trained technicians will continue to inspect and repair duct systems, as they are the key to energy efficiency. As much as 20% of the air that moves through a duct system can be lost to leaks and improper installation. We strive for efficiency, not only in the units we install, but in the entire system of your home.

Just Call John’s today to schedule a FREE ESTIMATE and learn how we can help you create an efficient and clean home environment.

5 Ways to Make Every Day Earth Day in Gilbert Arizona

Tuesday, April 29th, 2014

Even though Earth Day was last week, Gilbert Arizona is a great place to make every day Earth Day. From the 350+ days of sunshine to the hiking trails, there are opportunities to enjoy the outdoors year round. Being in the desert makes us more conscious of our water use – or it should – and we can all save a little on summer utility bills while helping the environment.

Here are five ways to make every day Earth Day in Gilbert Arizona:

  1. Go outside. There’s nothing better than the sun shining on your face. Enjoy the outdoors by taking a walk with a friend or play outside with your family. Take advantage of the near-perfect weather we have here in Arizona!
  2. Use less water. Turn the tap off when you’re brushing your teeth. It saves as much as four gallons a minute!
  3. Save electricity. Turn off lights when you leave the room. Cover south facing windows. They get the most sun throughout the year, heating up your home, and causing the A/C to run non-stop.
  4. Use reusable grocery bags. The average family visits the grocery store more than once a week. That makes for a lot of plastic and paper bags going to the landfill. Opt instead for reusable bags and make it ZERO bags going to the landfill.
  5. Hang clothes outside. There’s almost nothing better than the smell of clean sheets. Hanging clothes and linens outside saves the energy you would spend using the clothes dryer. And in Arizona, laundry doesn’t take long to dry!


Imagine how great a world it would be if we each made one small change to make every day Earth Day! If you’d like to learn about even more ways to save energy and money, read our blog, 10 Ways to Save Energy in Your Home.

Mesa Arizona is a Tree City USA Community

Friday, April 25th, 2014

We are pleased to be part of the Mesa Arizona community for many reasons, including that they have been named a Tree City USA Community by the Arbor Day Foundation.

What is Arbor Day?

Arbor Day was established in April 1872 by J. Sterling Morton, a Nebraska journalist and politician. He felt Nebraska’s landscape and economy would benefit from the planting of trees. Today, all 50 states, as well as many countries around the globe, celebrate Arbor Day by planting trees and educating people on the uses of trees.


How is Mesa Arizona, a Tree City US Community, celebrating Arbor Day?

This year, we celebrate Arbor Day on April 25th. As a Tree City USA, Mesa has the ability to improve community urban forests and educate on the importance of trees for communities and the environment. Join neighbors at 9:30am on Arbor Day at the Botanical Walk at 9320 E. McKellips Rd., where Zaharis Elementary students will assist in the planting of trees.

For more information, please visit the City of Mesa website.

Ways to Observe Earth Day Mesa, AZ

Tuesday, April 22nd, 2014

Today is Earth Day Mesa!

At John’s Refrigeration, we love being eco-friendly and helping our customers make their homes more energy efficient. We’re excited the Mesa community loves being green, too, especially on April 22nd, which is Earth Day.


When Did Earth Day Begin? 

The first Earth Day was celebrated April 22, 1970 by 20 million Americans. The event is now international; combining citizens, grassroots organizations, municipalities, and governments to spread the word about ways to protect the environment.

April is Valley Bike Month/Bike2Work Day

Observe Valley Bike Month when you Bike2Work on Earth Day. Stop by the north entrance of Mesa City Plaza for the Earth Day Expo. The event benefits a local charity and includes a pancake and smoothie breakfast from 6-8 am.

Celebrate Mesa 

Earth Day is about bringing communities together. Join your Mesa neighbors on April 26th and Celebrate Mesa. The event takes place 2 – 6 pm at Pioneer Park and includes fun for all ages. Bounce houses, carnival rides, food vendors, and tethered balloon rides are just a few of the fun things planned.

Water Awareness

April is Water Awareness Month. Join Mesa Mayor Scott Smith in the Water Awareness Campaign by pledging to conserve water and other natural resources. Learn ways to save water on landscaping with the tips offered on the Water Awareness website, including ways homeowners can receive rebates for removing grass and opting for eco-friendly landscaping options.

If we each do one small thing, we can change the world. April is a great time to learn ways to conserve resources and become more energy efficient. The team at John’s Refrigeration is passionate about helping you stay comfortable and energy efficient in and around your home.

10 Water Conservation Tips

Tuesday, April 15th, 2014

Conserving water is better for the environment, as well as for our wallets. Wasting precious water is almost a criminal offense, especially for those of us living in the desert. Conserving water is easy, though. A few simple steps is all it takes for everyone to protect this precious resource.


Here are 10 things you can do now to save water around your home:

  1. Repair leaky faucets and toilets. About 14% of indoor water use is lost to leaks.
  2. Showers are more water-efficient. It takes about 70 gallons of water to fill a bathtub, though long showers can use 5 to 10 gallons every minute, so keep showers brief.
  3. Load from the front. Most front-loading washing machines use around 20 gallons a load, while most top-loading machines use about twice that amount.
  4. Use a dishwasher. Energy Star dishwashers only use about 4 gallons of water per load verses hand washing, which generally uses about 20 gallons of water each time.
  5. Xeriscape. Nearly 60% of water usage goes toward lawn and garden maintenance, so replace your traditional landscaping with water-wise or drought-resistant plants.
  6. Cover it. The average pool holds 22,000 gallons of water and if you don’t cover it, hundreds of gallons of water can be lost due to evaporation every month.
  7. Drive a dirty car. Washing a car uses about 150 gallons of water, so cut down on the number of car washes.
  8. Turn it off. When brushing your teeth, just wet your brush and fill a glass to rinse your mouth; don’t let the tap run.
  9. Collect rain water. Although it doesn’t rain a lot here in the desert, collecting rain water, especially during monsoon, to water your xeriscaped yard will keep your yard looking lush.
  10. BYOB. Avoid using pre-packaged bottled water by filling your own bottle with tap water from home. Each one-liter bottle of water actually takes about three liters of water to produce.

John’s Refrigeration Heating and Cooling is not only committed to our customers, but also to the environment. John’s offers a home energy audit to find out where your home is losing energy. As your home comfort partner, call us so we can work with you to increase your home’s efficiency, reduce your energy usage, and save you money.



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?

Energy Savings: 10 Ways to Save in Your Home

Tuesday, April 8th, 2014

Energy savings is on the minds of most homeowners, even if saving money uses more of our brain cells. However, energy savings and saving money often go hand in hand.


Looking for ways to do both has never been easier with these tips:

  1. Switch your ceiling fan to turn in a counter-clockwise direction in the summer, but clockwise in the winter. However, be sure to turn fans off when you leave; fans only cool people, not rooms.
  2. Replace your a/c air filters once a month to keep your HVAC system running at optimal performance.
  3. Set your thermostat fan switch to “auto”; leaving it in the “on” position keeps air running constantly.
  4. Block the sun from overheating your home by using shades, blinds and drapes; outside, use awnings, trees and shrubs.
  5. Give your a/c a tune-up. Proper maintenance saves money and energy and lengthens the life of your HVAC unit.
  6. Open interior doors so that cooled or heated air flows freely throughout your home.
  7. Don’t block air vents with drapes or furniture so that air gets to where it needs to.
  8. Repair leaky ducts to reduce heating and cooling costs, as well as to keep pollutants from irritating allergies.
  9. Install a programmable thermostat to automatically adjust the temperature in your home.
  10. Give your HVAC system space to work efficiently. Never stack anything against or on it.

We discuss several of these tips in further detail on our site’s blog section, so click on the links to find out more so you can start saving energy and money today.
