Why Consider a Heat Pump?

January 16th, 2015

You may or may not have heard of a heat pump, a relatively new kind of heating system that’s gaining popularity across the country. Even if you have heard of it, you may not know how it works or why it’s worth choosing over a more traditional system. For those of you who are curious about the benefits of a heat pump, you’ve come to the right place. Read on to find out how a heat pump actually works, and what kinds of benefits it can provide.

What is a Heat Pump?

A heat pump is a non-combustion based system. That is, it does not burn fuel in order to create heat. Instead, a heat pump moves preexisting heat from a space that doesn’t need it to a space that does. It does this by utilizing two different parts of the system, an indoor unit and an outdoor unit. The outdoor unit is installed outside, while the indoor unit is installed inside, as you may have guessed. The two units are connected to each other by power and refrigerant lines.

When the heat is turned on, the outdoor unit evaporates refrigerant using a coil inside its casing. The gaseous refrigerant acts as a heat sink, pulling thermal energy from the surrounding air and into the coil. The thermal energy is then carried down the refrigerant line and into the indoor unit. There, the refrigerant gas is condensed back into a liquid state. This releases the thermal energy to warm the air before circulation.


There are multiple benefits to installing a heat pump in your home. The first is that a heat pump system is much more energy efficient than combustion systems. It only has to use electricity to operate, and garners the entirety of its heat from the surrounding environment.

The second benefit of a heat pump is that it can actually act as both an air conditioner and heater. It does this by simply reversing the flow of refrigerant through the system, taking heat from the house and releasing it outside. This saves you the space and expense of installing an entirely new system.

If you’d like to know more about heat pumps, call Johns Refrigeration. We provide heating installation throughout the Phoenix area.

What Are My Heating Options in Tempe?

January 15th, 2015

There is a huge amount of heating options available to homeowners today, so many that it can easily be overwhelming.

  • Do you want a combustion heater or a heat pump?
  • If combustion, what fuel do you want it to burn?
  • If heat pump, do you want a central unit or a ductless system?
  • If you aren’t sure about any of those questions, don’t worry.

We’ve got a short summary below of some of your heating options in Tempe.


Furnaces are the most popular kind of heating system in the country. They’re relatively cheap, versatile, and put out a lot of heat relative to the amount of fuel burned. Most furnaces operate on natural gas, which is piped in by the city. In areas where natural gas is not an option, however, electric and even wood burning furnaces are still an option. Furnaces are a great option for those who want a sturdy heating system that can last a long time.

Heat Pumps

A heat pump does not burn fuel to create heat, like furnaces do. Instead, it evaporates and condenses refrigerant to move heat from one area to another. This makes it extremely energy efficient, because it’s moving preexisting heat from outside into the home instead of creating it. It’s also safer, as it doesn’t have any toxic byproducts of its operation like furnaces do from burning natural gas. Heat pumps are a good choice for people who want to save money and live in more temperate climates.

Ductless Mini-Split Systems

A ductless mini-split is just like a heat pump, but built to only heat one room instead of the whole house. Why would this ever be desirable? Well, for one thing it avoids losing heat to leaks in the ductwork, something that a lot of forced air systems suffer from. For another, it offers the added ability to set a different temperature in each room with a ductless system. Ductless systems fit the needs of those who want a finer level of control over the climate in their home.

If you’re in the market for a new heating system, call Johns Refrigeration. We provide heating installation services throughout Tempe.

3 Tips to Fix Pressure Balance Problems in Heating and Cooling

January 13th, 2015

Did you know…the air in your home can be a negative, positive, or neutral pressure? It’s true and it’s one of the least understood – and most important – issues in heating and cooling. Ideally you want a neutral system, but finding the balance of negative and positive pressure can be challenging and can create different zones of heat and cold throughout your home.


Whether it’s positive or negative, too much pressure is not good for your home. Neutral air is the most energy efficient because it means there is no air escaping through cracks or unsealed ductwork and outside air isn’t entering the home. The best pressure in your home is neutral to slightly positive as it is also the most comfortable while preventing dust, pollen, and other contaminants from entering the home.

What’s negative pressure?

When too much air is drawn into your home, it creates a condition known as negative pressure. Dust, pollen, and environmental contaminants enter your home and can cause allergies, asthma, and health risks associated with dust, mold, and carbon monoxide. Some of these issues can be resolved by properly sizing and sealing ductwork, and installing weather stripping on doors and windows.

What’s positive pressure?

When conditioned air within your home is escaping through windows, doors, and cracks into the attic and elsewhere, positive pressure is created in your home. The system just heated or cooled the air and that conditioned air is flowing right out the door – literally. It costs you in increased utility bills.

An energy audit will determine if your home has a positive or negative air pressure, as well as the cause(s), and solution(s) to get your home to neutral pressure.

Just Call John’s to schedule an energy audit and learn about the pressure in your home today.

Can I Do My Own Heating Repairs?

January 5th, 2015

If you have discovered ways to perform multiple repairs around your household using your own tools and know-how, it’s tempting to think that you can apply this same dedication and independence to the central heating system that keeps the home warm during winter nights. After all, what’s wrong with trying to fix a small problem with a furnace or a heat pump on your own, rather than calling a professional contractor to handle it?

Actually, quite a lot is wrong with this! Although there are some basic maintenance tasks you can accomplish on your own, such as regularly changing a heater’s air filter, when it comes to repairing a heating system, you must leave the work to trained technicians. In fact, in many localities, it is illegal for anyone except licensed professionals to work on natural gas-powered heaters.

Thankfully, trained assistance for repair is readily available from Johns Refrigeration. We offer speedy, dependable heating repair services in Mesa, AZ and the surrounding areas, and we’ve helped homeowners stay comfortable since 1970. Call us whenever you experience difficulty with your residential heating system.

Why Heating Repairs Are Not DIY Jobs

Safety is the number one concern when it comes to fixing heating systems. The majority of home heaters are gas-powered furnaces, and it is vital that professionals handle any work associated with them. Not only are the repairs themselves potentially hazardous, but poorly done repair work can lead to a furnace that leaks carbon monoxide. Only professional work will give you reassurance after repairs are completed that the heater is working at its highest safety levels.

Even if you don’t have a gas furnace in your home but instead use an electric furnace or a heat pump, you still must leave repairs to professionals to make certain the work is done correctly. Modern furnaces and heat pumps are far too complex for amateurs to fix; in fact, simply diagnosing what is causing a malfunction is extremely difficult without years of training. An incorrectly applied repair is often worse than no repair at all.

Finally, professional heating repairs will go faster. Instead of struggling for hours or even days to perform repairs on your own that most likely won’t succeed anyway, you can call experienced technicians to take care of the work in only a fraction of the time.

The lure of saving money by going “do-it-yourself” may feel strong, but keep in mind that this is actually an illusion: a badly repaired heater will cost money because of future repairs and inefficient performance—and this is before you consider the potential safety risks! Don’t make this mistake: call on Johns Refrigeration for heating repair service in Mesa, AZ that will have your troubles solved for the long run.

The History of “Auld Lang Syne”

January 1st, 2015

There are numerous different traditional songs associated with Christmas—but there is only one song that comes to mind immediately when people think of New Year’s Eve: “Auld Lang Syne.” It is hard to find a New Year’s Eve party where people won’t leap into singing “Should old acquaintance be forgot…” as the first stroke of midnight sounds. This tradition encompasses the globe, with almost every culture that celebrates New Year’s on January 1st breaking into song with the same set of lyrics.

Where did this song come from? And what do the words “auld lang syne” actually mean? The best place to ask these questions is Scotland. The Official Gateway to Scotland website calls the song “one of Scotland’s gifts to the world, recalling the love and kindness of days gone by, but in the communion of taking our neighbor’s hands, it also gives us a sense of belonging and fellowship to take us into the future.”

The melody of the piece originates from Lowland Scots folk song tradition. It was legendary Scottish Romantic poet Robert Burns (1759–1796) who created the words we know today, however. During the later years of his life, Burns dedicated much of his work to collecting Scottish folk tunes and giving them new life. The first mention Burns makes of “Auld Lang Syne” is in 1788, when he calls the song “a glorious fragment.” Burns wrote new lyrics to the old melody, and used the words “auld lang syne,” which is Scottish for “old long since,” and which can be translated into standard English as “long, long ago” or “days gone by.” The phrase was already known in earlier Scottish poems and folk songs, and appears to be the equivalent of “Once upon a time…” for Scots fairy tales.

Soon after Burns introduced the song to the public, it spread across Scotland as a New Year’s custom, and then to the rest of Great Britain. Scottish immigrants took the song with them as they moved across the globe, and by the middle of the 19th century it was a holiday tradition throughout the English-speaking world. By the close of the 20th century, it was a global phenomenon to ring in the New Year.

We imagine that you’ll end up singing or hearing “Auld Lang Syne” at some point this New Year’s (maybe you’ve already heard it while watching It’s a Wonderful Life).

All of us at Johns Refrigeration would like to take this opportunity to wish you a happy coming year in the tradition of the song.

5 Facts about Santa Claus

December 25th, 2014

Many holiday traditions involve the story of Santa Claus, the lovable old man who spends most of his time at the North Pole taking a single evening to deliver presents and candy to children everywhere. But since Santa Claus is so elusive (unless he happens to be visiting your local shopping mall), how do we know so much about him? Where exactly does his journey begin? Our holiday guide details 5 of the most common traditions associated with Jolly Old Saint Nick.

  1. The Origins of Santa: The name “Santa Claus” comes from St. Nicholas (a name which became Sinter Klaas for short in Dutch), a Christian Bishop from 4 A.D. who was known for giving his fortune away to those in need in Turkey. Santa Claus’ first associations with gift-giving comes from Holland’s St. Nicholas’ feast day, during which children would leave out their shoes overnight and find presents waiting inside the shoes on the next morning.
  1. The Stocking by the Chimney: While many people associate Holland’s shoe tradition with the origins of hanging a stocking, this isn’t entirely accurate. Hanging stockings instead comes from the legend of a time St. Nick helped a man afford to marry off his daughter by throwing a bag of gold down the chimney, which landed in a stocking that was hanging up to dry.
  1. St. Nick’s Outfit: Santa got his fashion sense from a wooden cutout handed out during a meeting of the New York Historical Society in 1804. But it wasn’t until a 1930s Coca Cola advertisement that his traditionally blue, white, and green outfit was transformed into a big red suit.
  1. Leaving Cookies out for Santa: Food was traditionally used as ornamentation during the holidays in medieval Germany as apples and cookies commonly adorned the home at wintertime. When the Christmas tree became a common symbol of the season, edible treats began to vanish, a phenomenon which became attributed to Santa Claus’ snacking habits.
  1. Why Santa Drives a Sleigh: Santa gets his sleigh from a tale spun by Washington Irving, the same author who brought us the Headless Horseman. He wrote down an account of a dream in which Santa Claus drives a weightless wagon through the sky, and the stories became so popular, they stuck around.

Here at Johns Refrigeration, we hope that you have a joyful and safe celebration, no matter what holiday traditions you engage in this year. Happy holidays!

John’s Refrigeration Rave Review: Dust Allergy Solution

December 23rd, 2014

Dust Allergy Solution

Are you experiencing allergies or feel like your home’s air isn’t as clean as it could be? It’s time to Just Call John’s! Your home is a living being; inhaling and exhaling just like you do. When the ducts aren’t properly sized and sealed, the system has to work harder to heat and cool your home. It’s as if the home itself is having an asthma attack. The result is more dust and contaminants inside (instead of staying outside) and a temperature differential of more than a degree or two.

Our customer Joyce called us after hearing a rave review about John’s Refrigeration from her neighbor. She needed help with the amount of dust in her home and temperature differentials as much as five degrees on the east and west sides of her home. She has pets, but thought dusting once a day was excessive. And she was right.

We inspected the duct system and found the intake wasn’t sized properly and there were leaks. This meant dust was entering the home, along with air from the system, and airflow was inconsistent throughout the home. This created a need to clean the home frequently and be frustrated by varying temperatures within the home.

Solution and Results

We added a return, made a larger duct to the existing return, and sealed registers in an effort to keep dust, pollen, and other contaminants outside and the system running efficiently.

Joyce immediately noticed the quietness of the A/C when it was running. Over time, she also noticed less dust and has gone from dusting once a day to only twice a month! With just a few simple changes, we created more air flow, increased comfort, decreased the amount of dust, and make the system more efficient by properly sizing and sealing the ductwork.

Watch the video to hear how our work helped improve Joyce’s home:


How Does Energy Efficiency Factor into Furnace Installation?

December 19th, 2014

One of the main reasons to install a new furnace is to achieve better energy efficiency. But how do you know that your new system will be energy efficient? You’ll want to take a look at the AFUE rating.

What Is AFUE?

AFUE stands for annual fuel utilization efficiency, and it is the measurement of a furnace’s efficiency in converting fuel to energy. For instance, if you see an AFUE rating of 90%, this means that for every 100 units of fuel burned, your furnace will generate 90 BTUs (British thermal units). Put another way, an AFUE of 90% means that 90% of your total fuel usage goes toward heating your home; the rest is lost to exhaust that goes out your flue. Reviewing the AFUE rating will tell you not only how energy efficient the unit is, but how much money you can expect to save, depending on what the AFUE is. It is important to note that the higher the AFUE rating, the more expensive the unit will be.


A second way to assess whether or not a particular furnace is energy efficient is to see if it carries an ENERGY STAR sticker. The ENERGY STAR sticker will only appear on products that are at least 15% more efficient than the minimum standards. As such, any product with the ENERGY STAR sticker will have good energy efficiency.

Why Does This Matter?

Less fuel usage means lower monthly energy bills; the best way to achieve energy usage is to install an energy efficient furnace.

What Energy Efficiency Doesn’t Mean

There can sometimes be confusion about what having a more energy efficient furnace can mean, so we’ll explain here. Let’s say you are looking at a furnace with an AFUE of 95% versus a furnace with an AFUE of 90%. The furnace with the higher AFUE won’t heat your home better or faster than the furnace with the lower AFUE rating, it will heat it the same; the difference is that it will heat your home using less fuel, which is how a furnace with a higher energy efficiency rating can save you money.

Energy efficiency ratings can be a little confusing, so if you are having a hard time choosing a furnace for your home, call Johns Refrigeration today and schedule your furnace service in Mesa, AZ with one of our installation experts.
