Reasons to Schedule an Energy Audit

January 14th, 2014

If you are concerned about the high costs of energy in your home, then you should consider scheduling an energy audit from professionals. An energy audit is a thorough examination of your home to locate places where you are losing energy. Audit technicians inspect your home’s HVAC system, ductwork, insulation, attics, and energy-generating appliances, and then run tests to find leaks and energy inefficiencies. At the conclusion of the audit, your technicians will present you with a detailed report and recommendation for upgrading the various systems in your home to achieve better energy efficiency.

Johns Refrigeration is a Home Performance contractor with the U.S. government’s Energy Star program: our technicians specialize in helping homeowners achieve better whole-home energy efficiency. We can help you improve the efficiency of your cooling and heating system in Mesa, AZ with our services.

Here’s why you should schedule an energy audit

  • Reduce your bills: This is the primary reason people need to have an energy audit. It will result in lowering your power usage and save you money. An energy audit will provide you a detailed report that will show you what steps to take to have a more energy-efficient home. According to the U.S. Department of Energy, you can save around 16% (after accounting for expenses on improvements) each year using the knowledge from your energy audit.
  • Have a more comfortable home: Hand-in-hand with saving energy is improving your comfort level. Energy audits locate where your home is losing heat and what sealing needs to be done: improved insulation, radiant barriers, window films, etc. Not only will this reduce the strain on your HVAC system, but it will make you more comfortable as well.
  • Find repair issues: During an audit, the technicians may discover problems in your home that have remained hidden until then. Perhaps your heater has a malfunction that is making it work inefficiently, or the venting is poor. This will also lead to improved home safety, since it will protect you from possible carbon monoxide leaks and locate radon.

Schedule an energy audit today

It’s often a bit frightening to people to learn about what might be wrong with their home. But the benefits of an energy audit are too great for you to put it off. The recommended upgrades will provide you long-term savings, and you’ll know you’re doing your part for general energy conservation.

Audits require highly trained specialists, which is why you should contact Johns Refrigeration. Energy audits are one of our specialties. Our experts will help you find a path toward better energy-efficiency with your heating and cooling in Mesa, AZ.

Healthcare for your A/C has never been cheaper!

January 14th, 2014

When the temperature inside your home isn’t what you want it to be, you should be able to adjust the thermostat and feel more comfortable within minutes. The last thing you want to happen is to adjust that thermostat and have nothing happen (a “sick” a/c). No one wants to be too hot or too cold, especially here in Mesa.


At John’s, we understand the need to keep your a/c and heating system healthy and in top working order at all times. That is why we created our Peak Performance Club. With an annual maintenance membership, you get peace of mind in the health of your a/c and heating system. Here is what it includes:

Two (2) 51-Point Inspections (up to $259 value) –to identify anything that could shorten the life of the system, cause an excessively high utility bill or compromise your family’s safety.

Clean Indoor and Outdoor Coils ($190 value)* – to maintain proper airflow and prevent harm to compressor valves. To provide maximum cooling to compressor to extend its life and clear debris to allow for proper drainage to prevent rust.

Clear Condensate ($125 value) – To prevent costly water damage and the potential for mold formation.

These services provide a great starting point for keeping your system healthy and in excellent working order. But there are even more benefits to joining the Peak Performance Club! These benefits include:

Priority Service: You receive service first and ahead of non–club members.

Extended Equipment Life: Prolong the amount of time your heating and cooling equipment can continue to operate at peak levels.

Improved Efficiency, Safety and Savings: With periodic operational checks and performance tests, your HVAC system can perform safely and efficiently without demanding more energy. This means you save more money because your heating and cooling equipment is able to work with the greatest efficiency.

Fewer Breakdowns: Because regular maintenance often catches problems in the earliest stages, there is less need to worry if your heat will go out in the winter or if your air conditioning will stay on in the summer.

Discounts and Extended Warranty on Repairs: In the event your equipment requires repair, you receive special savings on our normal pricing. Plus, the best repair warranty in the industry: three years for Peak Performance Club Members (standard for non–club members is two years)

No Service Fees with Repairs–On–Demand Service: In the event your system requires a repair that you move forward with, the service fee is on us.

Easy Scheduling: You don’t need to remember to call us. We will contact you by e–mail, postcard, or phone letting you know when it’s time to schedule your next inspection.

Proof and Documentation: If you sell your home in the future, you will have proven documentation that your heating and cooling system has received proper maintenance and is in good working condition. Plus, your membership is 100% transferable.

When you join the Peak Performance Club you get all this for just $17 a month or $199.95 for the year. And you get the peace of mind that your HVAC system is being well cared for. You will have confidence that every time you adjust the thermostat, things will work the way they are supposed to. For more information on joining the Peak Performance Club, just call John’s at 480-648-2400.

What are the Benefits of an Energy Audit?

January 10th, 2014

An energy audit is a means of gauging the efficiency and heating/cooling retention ability of your home. A trained inspector arrives and analyses your home using a combination of expertise and equipment such as infrared cameras to spot potential shortcomings in your home’s energy retention, and to make suggestions on ways to correct those shortcomings.  Here in Mesa, heating repair services often offer energy audits, helping households respond to our desert climate with sensible energy solutions. What are the benefits of an energy audit? A few general answers can be found below.

  • It can help you plan for an HVAC upgrade. If you’re looking to install a new HVAC system or make new additions to an existing unit, an energy audit is an excellent way to begin your plans. It can tell you places that need improvement and spots that require attention, which can help you prioritize your options and perhaps decide on the type of HVAC system is right for you.
  • It can save you money. You may notice that your energy bills are going up every month, but have no idea how or why that is happening. An energy audit allows you to pinpoint the source of the problem and correct it with confidence, knowing that it will lower the cost of your monthly bills in the bargain.
  • It can improve energy efficiency. By acting on the findings of an energy audit, you can improve your home’s ability to retain a set temperature, reducing overall costs and improving its resale value in the bargain. Hat can save you a great deal of money over time: enough to offset the cost of the audit itself in some cases.

In Mesa, heating repair and energy audit services are provided by John’s Refrigeration. Our Mesa, AZ heating repair technicians know what the benefits of an energy audit are, and can provide a thorough analysis of your heating and cooling needs. If you’re looking to change your existing HVAC system, or just want some ideas on how to improve your home’s energy efficiency, give us a call today. Our staff of trained professionals is standing by to help!

New Year’s Traditions Explained

December 31st, 2013

2014 is almost upon us, and with the coming of the New Year, we thought we’d take a brief look at some of the more popular traditions associated with this holiday. It’s been around for at least 4,000 years: as long as we’ve figured out how long it takes for the seasons to come and go. Here’s a quick discussion about some of our more modern traditions and where they started:

  • Auld Lang Syne. The famous song began in Scotland, where it was published by Robert Burns in 1796.  He claims he initially heard it sung by an elderly resident of his hometown, which suggests it has traditional folk origins even before that. It became even more popular when big band leader, Guy Lombardo, started playing it every New Year’s Eve, starting in 1929 at the Roosevelt Hotel in New York City.
  • The Dropping of the Ball in Times Square. The tradition of dropping the ball in Times Square started in 1907. It was made out of iron and wood with light bulbs located on the surface, and the ball originally “dropped” over the offices of the New York Times at One Times Square. Dick Clark famously broadcast the event every year from 1972, until his death in 2012.
  • The Rose Parade. The Tournament of Roses Parade has been held in Pasadena every year since 1890; taking advantage of California’s warm weather to present a parade of floats, bands and horses. A football game was eventually added to the festivities in 1902, when Michigan dominated Stanford’s team by a score of 49-0
  • Baby New Year. The use of a baby to signify the New Year dates back to Ancient Greece, where it symbolized the rebirth of Dionysus (the God of wine and parties). Early Christians initially resisted the pagan elements of the story, but soon came to adopt it since it matched the traditional Christmas symbol of baby Jesus in the manger. Today, people of all faiths and traditions refer to the New Year as a baby, representing new beginnings.

Whatever traditions you choose to celebrate, we here at John’s Refrigeration wish you the very safest and happiest of New Years. May 2014 bring you nothing but the best!

Know the Defrost Cycle on Your Heat Pump

December 27th, 2013

Now that it’s cold in the evenings and especially the early mornings, many of us are turning on the heat. While Phoenix is known for its stifling desert heat, freezing temperatures are not unheard of. If you do not have gas in your home you most likely have a heat pump heating system. When is gets really cold our heat pumps are designed to go into a defrost cycle. Understanding your heat pump’s defrost cycle will help you know when something is wrong or if it’s running properly. After all, we don’t want to worry about being able to warm those feet before they hit the ground running in the morning.


Because of the colder temperatures outside, the outdoor coil on your heat pump is cold which can cause frost to form on the coil, which then blocks air movement through it. In order to remove the frost, the heat pump first detects the buildup of ice on the outdoor coil, then it essentially puts itself into cooling to make the outdoor coil hot and defrost the ice.

When the heat pump detects the ice has melted, it terminates the defrost mode and starts to heat normally. A heat pump running in defrost cycle will have a few tell-tale signs.  The fan may blow cold air into your home instead of warm. Other signs your heat pump may be in defrost cycle include the fact that the outside unit is humming, but the fan outside is not running. There may also be steam or smoke outside and water is around the unit or on the roof.

If you witness any of these symptoms, simply leave the unit on and let it run for 15-20 minutes. The unit must run in order to complete the defrost cycle. If the symptoms persist after the unit has run for 15-20 minutes, call John’s and we will send out one of our N.A.T.E. Certified Service Consultants to help. We pride ourselves on being your year-round indoor comfort providers.

Longer Days Ahead: Why Winter Solstice Is a Reason to Celebrate

December 24th, 2013

Holiday greetings from all of us at Johns Refrigeration!

December is a time of celebrations across the globe, despite the cold weather that affects much of the countries in the Northern Hemisphere. In fact, the cold weather is one of the reasons that it is so important for people to embrace celebrations of light, color, food, and warm drinks—what better way to cheer up during a time of short days and low temperatures?

There is another reason to feel joy at the end of December, regardless of your religion or culture: an astronomical event called winter solstice.

Four astronomical markers divide the seasons on planet Earth: two solstices and two equinoxes. Equinox(a combination of the Latin words for “equal” and for “night”) is the point in Earth’s orbit when its axis is parallel to the Sun. Solstice (from the Latin words for “sun” and “to stand still”) is the point in orbit where the Earth’s axial tilt points toward the Sun. During the equinoxes, which occur at the start of spring (vernal equinox) and fall (autumnal equinox), the periods of day and night are the same length. During the solstices, which occur at the start of summer (June solstice) and winter (winter solstice), either day or night is at its longest period. June solstice is the longest day of the year; winter Solstice is the shortest day of the year.

Occurring on the 20th or the 21st of the month (this year it falls on the 21st), winter solstice marks the official beginning of winter, but also the point at which the days start to grow longer once more. The sun, which has dropped lower in the sky since the June solstice (June 20-21) and reaches its lowest point above the horizon on noon on winter solstice, once again begins to rise.

From the earliest human prehistory, people have recognized the winter solstice as an important event in their lives. When winter survival was difficult for early human societies, the sight of the sun beginning to rise in the sky once more was a symbol of hope and a reason to celebrate.

(All of the above applies to the Northern Hemisphere of Earth. The equinoxes and solstices flip in the Southern Hemisphere. For example, in Australia, Christmas is a summer holiday.)

However you commemorate and observe this time of year, we hope you and your family have a joyful and safe season!

How Your Thermostat Affects Your Heating

December 18th, 2013

Your heating system (and your air conditioning system too, for that matter) is usually controlled by a thermostat: the little control panel on your wall that helps you regulate the temperature in your home. Thermostats largely employ digital technology, which can let you program specific times for it to turn on and off (among other things). Because your thermostat allows you to control your heat, it can wreak havoc when problems arise with it. Here’s how your thermostat affects your heating.

A thermostat uses a bi-laminated metal strip (a strip composed of two different types of metal) to detect the changes in temperature in the room. Metal expands and contracts with temperature changes, and the two types of metal expand and contract at different rates which can be measured to determine the right omen to turn on the heat. The strip itself is coiled; a temperature adjustment lever sits in the center and a mercury switch sits on the end. When the coil winds to a certain level determined by the lever, it tips the switch and starts the heating process. When the strip unwinds to a certain level, it trips the level back and halts the heating process.

Many thermostats also use a heat anticipator, which shuts the heater off just before the proper temperature is reached. This helps the thermostat be more accurate, since the anticipator allows the remaining hot air in your ducts to reach its location without going over the assigned temperature.

Needless to say, if one of these components is faulty, the entire heating system can be affected. If the thermostat misreads the temperature, it will turn the heater on and off at inappropriate times, while damage to the switch or lever will prevent the heat from turning on or off at all. The bad news is that the thermostat usually needs to be replaced in such circumstances. The good news is that a trained technician can do so fairly quickly, without a lot of fuss and bother. Johns Refrigeration can advise you on how your thermostat affects your heating, and perform repairs or replace the unit with courtesy and professionalism.

How Do I Know If I Need To Replace My Current Heater?

December 10th, 2013

Here in Mesa AZ, heating installation and heating repair primarily hit us in the winter, when desert temperatures drop and air conditioning units get shuttered for the season. Similarly, it can be hard to tell when you need to replace your existing furnace or boiler with a new one. There are subtle (and some not so subtle) signs that can alert you to the issue if you look for them. “How do I know if I need to replace my current heater?” you ask. A few of the most common signs are outlined below.

  • Your existing heater is old. His isn’t a make-or-break proposition, especially if you’ve given your heater lots of care and maintenance over the years. A well-kept heater can last for months or even years after its “expiration date.” However, if you spot some of the other signs on this list and your heater is more than 10 years old, you should probably think about replacement.
  • Higher bills. This can include bother more extensive repair bills and a higher cost of operation from month to month. As heaters get older, the wear and tear means a lack of efficiency. Replacing your heater with a new one – preferably one with a high AFUE (Annual Fuel Utilization Efficiency) rating can save you a great deal of money on these costs.
  • Recurring problems. Recurring issues such as a lack of overall heat and low air flow could signal a heater that is ready to be replaced. If you’re looking at problems that don’t seem to go away, no matter how many times a service technician inspects the heater, replacement may be the best way to save you time and aggravation.

If you’re asking “How do I know if I need to replace my current heater?” then the Mesa heating installation experts at John’s Refrigeration can help. We work in Mesa, AZ, heating installation is one of our specialties, and we can discuss your replacement options with you if your existing heater is no longer doing the job.

Thanksgiving, 2013: The Presidential Turkey Pardon

November 25th, 2013

Thanksgiving began in 1621, but didn’t become a national holiday until 1863, when Abraham Lincoln declared it in hopes of bringing a divided nation together. We have many Thanksgiving traditions in this country, from turkey at the meal to the annual Cowboys and Lions games on television. But one of the most beloved is the annual Presidential turkey pardon, in which the U.S. President “pardons” a turkey to life in a petting zoo rather than ending up as someone’s main course. As we celebrate this Thanksgiving, we thought you’d like to know a little more about the history of this fascinating tradition.

Farmers have sent turkeys to the White House as far back as the 1800s, hoping to have the honor of providing the President’s annual meal. There have been scattered stories of individual turkeys being “pardoned” throughout that time, including one in which President Lincoln’s son Tad successfully convinced the president to spare a bird intended for the family’s Christmas dinner.

Starting in 1947, the National Turkey Federation became the official supplier of the President’s Thanksgiving birds. The White House arranged for an annual photo op that year with the President receiving the turkey in the Rose Garden. Sadly, there was no pardon as yet; those birds all ended up on the Presidential table.

The push for an official pardon picked up steam in 1963, when President Kennedy ask that the bird be spared just a few days before his assassination. President Nixon opted to send each of the birds he received to a nearby petting zoo after the photo op, though there was no formal pardon attached.

But it wasn’t until 1989 that the pardon became official. On November 14 of that year, President George H. W. Bush made the announcement, and sent the bird to a Virginia game preserve to live the rest of its life out in cranberry-and-stuffing-free bliss. Since then, every President has held an annual pardoning ceremony, with the lucky turkey spared the axe and sent off to live in peace. Since 2005, the pardoned birds have gone to Disneyland in Anaheim, California where they have lived as part of a petting zoo exhibit in Frontierland.

No matter what traditions you enjoy this holiday, or who you enjoy them with, all of us here wish you a peaceful and happy Thanksgiving weekend.
