Healthcare for your A/C has never been cheaper!

Tuesday, 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.

How an Air Conditioner Works

Tuesday, November 19th, 2013

Most people understand that their air conditioning systems use a fan to blow cold air throughout their home but few people understand how they’re able to remove heat from your home. Having a basic understanding of the air conditioning process is a great way to be able to identify problems and know when you need to call for repair. John’s Refrigeration offers a full range of Mesa, AZ air conditioning services and we wanted to share a little about how an air conditioner works.

Mesa, AZ Air Conditioning Tip: How AC Works

Take a look below to learn a little bit about how your air conditioning system removes heat from your home.

Compressed Refrigerant

Think of a can of compressed air that you use to clean your computer. When you squeeze the trigger air blasts out and the outside of the can gets cold. This happens because that remaining air inside the can has to expand and fill the space left by the exiting air. The expansion of that air requires energy so it pulls in all the heat energy it can from the area around it thus making the outside of the can feel cold.

The Split System

If you have a central air conditioning system then you likely have an indoor unit and an outdoor unit which is why the system is often referred to as “split”. The outdoor unit contains a fan, a set of condensing coils and a compressor. The inside unit contains another fan and the evaporator coils.

The Refrigeration Process

So here’s how all the pieces fit together. The compressor in the outdoor unit compresses the refrigerant and then circulates it inside to the evaporator coils where the pressure is released causing the coils to get very cold. A fan in the indoor unit pulls in warm air from your home and passes it over the evaporator coils where the refrigerant absorbs heat and cools the air. The now-hot refrigerant then continues outside where it enters the other set of coils in the outdoor unit and its heat is exhausted by the other fan. The process is then repeated.

If you’ve noticed any type of problem with your air conditioning system or if you need to have a new one installed call the Mesa, AZ air conditioning service experts at John’s Refrigeration.

Peak Performance Evaluation Home Energy Audit

Wednesday, November 13th, 2013

John’s Refrigeration Heating and Cooling takes a holistic, whole house approach toward optimizing how your home, duct system, A/C system, and insulation work together. We offer a Peak Performance Home Evaluation–a home energy audit–which assesses the whole house as a system, not just the A/C unit and ductwork. This energy audit is designed to provide you with the best solutions to lower utility bills and improve your home environment, including temperature comfort, indoor air quality, and safety.


After John’s has conducted this test on your home, you will have specific recommendations for improving your central air conditioning system efficiency. Ensuring that you have the right size system will help you to enjoy reduced energy bills. We’ll also make sure you have the proper insulation, effective air flow, and no leaks in your ducts – or anywhere else – that could allow cool or warm air to escape into the spaces in your home that don’t need it.

We perform a Duct Efficiency Test where we compare air in vs. air out.  This tells us whether there is duct leakage, how much air the HVAC unit is delivering, and if your home has the proper duct size. We also test the leakage rate of your duct work. If more than 20% of the air moving through the system is leaking into spaces you do not want heated or cooled, we’ll seal them. Then we insulate your ducts to protect them from excessive heat and cold. John’s is authorized by both SRP and APS for duct testing and repair, which means that our customers may quality for rebates which will save you even more money.

The Peak Performance Home Evaluation home energy audit will also tell us where we can install dampers to make sure some rooms aren’t warmer or cooler than others. By optimizing the air flow throughout your air conditioning system with these actions, you are likely to see lower utility bills and be more comfortable in your home.

We’re confident you’ll choose John’s for the best in year-round indoor comfort.

Energy Saving Air Conditioning Tips

Monday, November 11th, 2013

We all need to run our air conditioning systems a lot here to stay comfortable. But with energy prices seemingly on the rise all the time, what can homeowners do to make sure that their AC is running as efficiently as possible? John’s Refrigeration is a family owned business and we’ve been offeringprofessional air conditioning service in Mesa, AZ, including repair, installation and maintenance services since 1970. We wanted to offer some of tips to our customers to help them reduce their energy usage and increase their home’s efficiency. Call us today to talk with one of our NATE-certified specialists about any services that you might need.

Mesa, AZ Air Conditioning Tip: How to Save Energy

These are a few of the things that you can do to increase the energy efficiency of your home and reduce your energy usage.

  • Regular maintenance – Your air conditioning system likely comprises a large portion of your home’s energy bill. If it isn’t regularly maintained then it will develop small problems that cause it to have to work harder to cool your home. But when you get it regularly inspected, cleaned, repair and tuned up, then you know that it will be operating at peak performance.
  • Energy audit – A great way to find out where your home is losing energy is with a home energy audit. This involves a visit from our technicians as well as a whole-home inspection. We’ll then offer a plan of action to address any areas of inefficiency and energy loss.
  • Insulation – One of the most important components of your home’s energy efficiency is the insulation—particularly in your attic. As the sun beats down on your attic it will heat up. That heat can leak into your home if the insulation in your attic is thin, old or rotting.

When you need any Mesa, AZ air conditioning repair, installation, maintenance or replacement just call the experts at John’s Refrigeration. We would love to talk with you about we can work together to increase your home’s efficiency and reduce your energy usage.

Programmable Thermostats

Tuesday, November 5th, 2013

Most people choose a programmable thermostat over a traditional thermostat to help manage energy costs. These devices save money by helping to cool or heat the home when rates are off-peak or when no one is home. Now there are thermostats that can even be accessed through an app, which means you can manage the temperature of your home right from your cell phone or tablet!


A programmable thermostat is designed to adjust the temperature in your home according to a series of programmed settings that take effect at different times of the day. For example, during the summer, this device may be set to allow the temperature in the house to rise during the workday when no one is home. It may then be set to turn on the air conditioning before you get home, allowing the house to be cool upon your arrival. The reduced cooling required during the day also means you’re saving energy during the peak outdoor temperatures and money when energy costs are highest. According to the Department of Energy, “You can save as much as 10% a year on heating and cooling by simply turning your thermostat back 3-5°F for 8 hours a day from its normal setting.”

During the winter, the programmable thermostat may be set to a cooler temperature while the house is unoccupied during the day and at night after everyone has gone to bed. Just as in the summer with the cooling of the house, the programmable thermostat can be set to raise the temperature prior to your coming home in the evening or waking up in the morning.

The pre-programmed settings that come with this type of thermostat are intended to deliver energy and utility savings without sacrificing comfort. Depending on your family’s schedule, you can notice significant savings in a short period of time by merely adjusting those settings appropriately for your lifestyle. Think of a programmable thermostat as the energy command center of your home; it’s like the brain that tells your HVAC unit how and when to pump air through its ducts.

Using a programmable thermostat in your home is one of the easiest and least expensive ways you can save energy and money. The key to saving is in establishing appropriate settings that automatically reduce heating and cooling in your home when you don’t need as much. Maximize the efficiency of your heating and cooling system by installing this money saving device or allow John’s Refrigeration to install one for you. If John’s installs a programmable thermostat for you, we will program it for you based on your schedule.

Common Air Conditioning problems

Monday, November 4th, 2013

When you run your air conditioning system as much as we do here in Arizona it can develop several common problems. Here a John’s Refrigeration we offer a full range of air conditioning repair services in Mesa, AZ for many different types of cooling systems. We’ve been in business since 1970 and we wanted to share some of the most common problems that we see. Give us a call today and one of our NATE-certified air conditioning technicians will be able to help you with any services that you need.

Air Conditioner Repair Tips: Common Issues

Here are a few o of the most common problems that homeowners face when it comes to their air conditioning systems.

  • Not enough cooling – We often get calls from homeowners who say that their AC is blowing warm air or that their home isn’t getting cool enough. This could be caused by low refrigerant in the system, a broken compressor, a bad fan motor or a clogged air filter.
  • Noises – When your air conditioning system starts to make strange noises it’s time to call for Mesa, AZ air conditioning repair services. Your AC has a number of moving parts and if they break down they will start to make noise. Squealing usually indicates that the fan motor belt is bad. Hissing often is a sign of a refrigerant leak and gurgling can mean that you have low refrigerant.
  • Clogged air filter – Probably the most common cause of air conditioning repair is a clogged air filter. If your AC’s air filter gets clogged with dust and dirty it will restrict the flow of air through the system. This could lead to insufficient cooling, increased repair, decreased efficiency and much more.
  • AC won’t turn on – If you air conditioner won’t turn on then you have a big problem. But sometimes this could be something simple like the AC has become unplugged. But it often is more serious than this. It might be that the motors’ capacitors are bad, that the motors themselves are broken or that the thermostats in your home need replacing.

When you need professional air conditioning repair service in Mesa, AZ, make sure that you call John’s Refrigeration.

Asthma, Allergies, & Indoor Air Quality

Friday, September 13th, 2013

Allergy and asthma control begins where we spend 90% of our time: at home. Controlling the air quality in your home can reduce allergy and asthma symptoms and decrease the triggers that cause flare-ups.

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 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.

Pollen and your HVAC system

Friday, June 28th, 2013

Many people move to the Phoenix metro area from other parts of the United States thinking their allergy problems will go away. But Arizona’s desert dust creeps into every nook and cranny of our homes, though there are many things we can do to prevent this pollution intrusion.

Poor indoor air quality is a major pathway for pollen and many other airborne pollutants. A poorly maintained a/c unit and compromised ducts can be prime real estate for germs. Inefficient filters can be home to many types of bacteria and viruses. Air coming through leaky doors and windows circulates dust, pollen, gasses, and odors through your home. And while some bacteria will cause odors, others won’t, so don’t count on a tell-tale scent to know if your system is housing mold and other pollutants.

Pollen is by far the most difficult allergen to avoid. All types of plants generally favor warm, sunny days for releasing pollen, and they prefer the kind of dry air typical of Arizona. Although these pollen grains are tiny, compared to other allergenic particles, they are big and heavy. This makes them easier to trap in an efficient filtering system.

Between proper air balancing, duct sealing, and using the correct filter, you can prevent pollen and other allergens from getting in your house, significantly reducing allergies and asthma symptoms.

John’s Refrigeration Heating and Cooling offers several solutions to your filtering problems. Our Advanced Oxidation Air Purifierwill reduce 97% of airborne bacterial and 97% of the airborne mold in your home.

Our Electrostatic Air Filtersare more than 84% plus efficient, versus 15% efficiency for the disposable filters commonly used. These reusable filters are also backed by a lifetime warranty.

John’s can improve the air quality in your home because we take a holistic, whole house approach and understand how your home, duct system, and A/C system work together.

Monsoon Season in Arizona

Thursday, June 13th, 2013

Arizona’s official monsoon is June 15th through September 30th. These storms range from minor dust storms to intense thunderstorms. The monsoon usually starts with heavy winds, which can turn into a wall of dust hundreds of feet high moving across the Valley. These dust storms, called haboobs, are often accompanied by thunder and lightning and sometimes lead to heavy downpours. It’s the only season during which Arizonans don’t use the phrase “it’s a dry heat”.

The Arizona Division of Public Health Services describes AZ heat as “more than a nuisance – it is lethal.” And the severity of annual monsoons affects our roadways – including driving visibility and flash flooding – as well as air quality. A 10,000 foot-tall wall of dust, 30 or more miles wide can do a lot of damage, especially to a home’s HVAC system.

Since a home’s air conditioning system filters the outside air, the dust storms that are part and parcel of a monsoon can strain your unit, making it work harder and less efficiently. Because the a/c unit may run longer than normal due to the higher humidity, homeowners may need to lower the thermostat setting in order to keep comfortable. 77 degrees in a 50% humid home does not feel good. Cleaning the unit’s condensate drain will also help keep your HVAC system clean and clear out any debris, which makes the unit more efficient.

Because the electricity often goes out during the monsoon, it’s best to turn your air conditioning unit off so there’s not a huge power draw when the electricity comes back on. In fact, investing in surge protection is also a wise move, considering you’re a/c is the biggest power draw in your home.

Although you should call John’s Refrigeration Heating and Cooling if you have issues with your a/c unit during the monsoon, after all the dust has settled, make an appointment with us and our certified technicians will check your home’s HVAC, including duct work and air quality, to ensure your family is breathing fresh air. After all, we are your indoor comfort specialists.
