What is the Condensate Pan?

July 25th, 2014

When you have a glass of cold water on a hot day, condensation forms outside of the glass as the water comes into contact with the warm outside air. Similarly, the evaporator coil of your air conditioning system collects condensation that needs somewhere to go as it forms. This is where the condensate pan comes in, an important component of the air conditioning and dehumidifying process.

Your split system air conditioner has two major components, the indoor evaporator unit and the outdoor condenser unit. As refrigerant cycles throughout your home, heat is absorbed at the evaporator coil and released at the condenser coil. Cool air is supplied to your home as a fan blows warm air over the cool evaporator coil. But this process not only cools your home; it also removes some humidity from the air to keep you comfortable. If there is moisture in the air, it collects on the evaporator as condensation when warm air blows over the cool coil.

Of course, this moisture needs somewhere to go. Condensation must drain quickly so that it does not overflow or back up into your system. First, it flows into the condensate pan, a shallow tray that collects water before it moves to the condensate drain line. The water then drains either outdoors or directly into a drain pipe.

One common air conditioning problem often caused by the condensate pan is water leaks. If your air conditioner is leaking it is most likely due to the condensate pan or drain. There may be cracks or tears in the pan, which would then need replacement. Alternatively, the drain line may clog, which means water backs up into your AC or overflows into your home. An AC technician can repair these leaks and check for other damages to your system.

Air conditioning repair and maintenance technicians are the best people to call when you run into leaks or other problems with your air conditioner. Call Johns Refrigeration for more information or to schedule air conditioning service in Mesa.

How does a dust storm affect my air conditioning?

July 23rd, 2014

The official monsoon season started in Arizona on June 15th and lasts through September. Often, along with rain, comes a dust storm; the worst of which is referred to as a haboob. In addition to causingallergies that drain your health, these storms can take a drain on your air conditioning unit.

How does a dust storm affect my air conditioning?

Much like our bodies, an air conditioner runs slower when there is dust and debris in the air. When the air is heavier, we get more tired doing our everyday tasks. We feel sluggish and need to exert more to accomplish the same activity. It’s the same for your air conditioning.

A typical monsoon storm begins with heavy winds, bringing dust across the Valley and into your home. Dirt enters the air conditioning unit, making the coil dirty, which reduces the unit’s performance. That means the unit is working harder and using more electricity to bring your home to the desired cool temperature. As a result, you will have a higher utility bill or may need additional maintenance to keep the unit clear of dust and debris.

How can I keep my air conditioning unit healthy during a dust storm?

Improving indoor air quality isn’t just for monsoon; it needs to happen throughout the year. At John’s Refrigeration we can:

  • Identify areas of the HVAC system where there are leaks that are allowing dust, pollen, and other contaminants into the home.
  • Install an electrostatic air filter that attracts and holds airborne particles so they do not enter your home or your lungs.
  • Clear the air conditioning unit of debris to help it work more efficiently.

The team at John’s Refrigeration is dedicated to helping families feel comfortable in their homes, during dust storm season and throughout the year. Call us today to learn how we can help keep your air conditioning running efficiently.

How to Reduce Strain on Your Air Conditioner During a Heat Wave

July 18th, 2014

“Heat wave” is a relative term in the Valley of the Sun. Standard summer days in Tempe count as roasting heat waves for most other parts of the country. So what we might call a “heat wave” mean that it isextremely hot. Either way, we have numerous days that will place enormous stress on the cooling systems in our home, and this pressure will cause them to wear down faster, leading to repairs and a shortened service life.

But there are ways to take some of the strain off your AC during the worst of the heat. Although you will depend on your air conditioning in Tempe, AZ to help you through most of the summer, you can relive the work stress placed on it through a few basic steps and some professional assistance from an experienced AC company like Johns Refrigeration.

Here’s our advice for keeping a healthier cooling system during the days of the Anvil of the Sun.

Have Regular Maintenance from a Professional

You should have a maintenance visit from an HVAC technician annually, no matter the weather. The best time to have maintenance done is in spring, but it is never too late to schedule it during the summer. Without maintenance, your air conditioner will start to run with additional stress. This will not only raise your power bills, but will cause the air conditioner to overwork. You risk a serious breakdown during the summer each time you go without a maintenance visit that year.

Maintain a Steady, Comfortable Thermostat Settings

Thermostat control is something people rarely do well during a heat wave: they crank the thermostat down to the lowest possible setting (usually 50°F) to combat the higher temperature. However, the thermostat is not a throttle: it will not producer higher levels of cooling when set lower, it will only remain on longer to try to reach the lower temperature. This puts enormous stress on the system, and it will result in a temperature that is too low for comfort. Instead of dropping down to the lowest setting possible, set you the thermostat at around 72°F, which is comfortable for most people, and keep it there. The AC will work less and you won’t sacrifice comfort.

Reduce Extra Sources of Heat

Watch for places in your home that produce additional heat that contributes to the high outdoor temperatures. Draw the blinds over windows that face the sun. Turn off all unnecessary lights. Avoid using appliances such as washing machines, dishwashers, laundry machines during the hottest parts of the day. Keep doors and windows closed. If you have an attic, make sure that it is properly insulated, since it will become incredibly hot from sun exposure and this heat will seep down into the rest of the house.

To get started with easing the stress on your air conditioning in Tempe, AZ, call Johns Refrigeration and sign up for our Peak Performance Club. We offer two 51-point inspections each year (the second is for your heater) and many other membership benefits.

It’s the summer in Phoenix so it must be monsoon season!

July 15th, 2014

Late June and early July bring hotter temperatures and humidity to the Arizona desert in the form ofmonsoon. Marked by rainfall, high winds, and dust storms, Arizona receives half its annual rainfall during this season. While some might argue whether it is a monsoon by the strictest definition, we know for certain the rainfall brings added humidity that affects air conditioning units.

Dust, pollen, and other contaminants can strain your air conditioning unit, making it work less efficiently. The unit may, for example, run longer than normal due to the added humidity in the air. We’re not used to the moisture in the air and often lower the thermostat of an already taxed system just to stay comfortable.

How can we make sure the air conditioner works efficiently during monsoon season?

  • Clean the unit’s condensate drain of debris so it can operate efficiently.
  • Hose down the condenser coil after you turn off the electricity to the outdoor unit. The cleaner the coil, the more efficiently the hot air can be cooled.
  • Change the filter on a regular basis so the house can breathe. Yes, your home breathes much like we do. If the air is dirty or the filter is clogged, the system will pull in dirty air from the outside to the inside of your home.
  • Make sure the ductwork is sealed to prevent dust and debris from entering the home.

The most important thing you can do to keep your air conditioner running efficiently during monsoon is to have an annual maintenance check completed. At John’s Refrigeration, we offer the Peak Performance Club to keep your system running efficiently and keep you comfortable in your home. Contact us today to learn more.



Have a cleaner home with an air conditioning install

July 8th, 2014

You come home from a day of work and your house is warm.

You turn the thermostat down, but it’s just not cool enough.

It’s the summer and you’re feeling the heat in your own home.

At John’s Refrigeration, we believe in helping our customers maintain a comfortable home at an affordable price. We offer our Peak Performance Club to maintain the health of your air conditioning system through the hot Arizona summers. For as much maintenance as we can do, there will come a time when you will need a new unit.

While an air conditioning install is a big cost, there is one big advantage – a cleaner home!

A new air conditioning unit brings a cooler, quieter, more energy efficient home.

There’s no need to worry if your home is cool when you get home from a long day.

There’s no need to constantly turn the thermostat down to keep the house comfortable.

And most importantly, an efficient system means less housework.

When the team at John’s Refrigeration installs a new air conditioner, we check the entire system to be sure it is running at top efficiency. This includes checking the ductwork for leaks, installing the proper size ducts and air returns, and making sure the air filter is the right size for the unit. It’s how we help our customers stay cool through the hot summer.

When your home is sealed properly after an air conditioning install, you can rest assured the air in your home is healthy. You will have to clean less because dust, pollen, and contaminants are outside the home where they belong. This means less dusting and vacuuming and more time to spend with family and friends. To learn more, please contact us today.

AC Services You May Need During the Summer

July 4th, 2014

The summer is the time of year when you need to take care of your air conditioning the most, because it’s the time that you need it to take care of you the most. A harsh summer in Arizona can almost refine harsh, and you need to have a good company ready to provide you with AC service in Mesa, AZ when your comfort comes under threat.

Here are some services you might need for your air conditioner during these summer months. Call Johns Refrigeration for the quality work from NATE-certified technicians that will keep your AC humming away.

Some Services for the Summer Air Conditioning Season

  • Maintenance: If at all possible, you should have maintenance done for you air conditioner in the spring, before the heavy summer heat hits. However, if you didn’t get it done during the spring, it’s never too late schedule it! (Please, don’t decide to put it off until “next year.” Skipping even one year will result in a loss of efficiency and puts the system at risk of repairs or even a breakdown.) A maintenance visit won’t take long, and it will make sure that your system will be able to make it through the rest of the summer providing you with efficient performance.
  • Thermostat upgrade: If you want an improvement in your air conditioner’s cooling and efficiency, you can upgrade your thermostat—it’s an easy way to increase performance without needing to have a major interruption in service. If you have an older manual thermostat, than upgrading to a digital programmable model will give you a level of precision that will save energy and deliver better comfort. You can also upgrade to a Wi-Fi thermostat and control the temperature in your house from wherever you have a wireless connection.
  • Repairs: No matter how well you maintain your AC, it can still encounter malfunctions that will cause serious inconvenience to you if you don’t act on it quickly. The moment you receive a warning from your air conditioner that something is amiss—odd noises from the cabinet, acrid smells from the vents, drop in airflow, ice appearing along the indoor coil, compressor shutting off early—call for repairs. Remember, the sooner you have repairs done, the more future repairs you avoid.

Preparation is the best way to stay cool with your air conditioner during an Arizona summer: call Johns Refrigeration today and schedule a maintenance visit; the peace of mind alone is worth the investment.

You can call us for any AC service in Mesa, AZ you need.

3 Common Problems with Air Conditioning Blowers

June 30th, 2014

It’s hot here in Mesa, with average daily temperatures landing somewhere between 104-105 degrees. Clearly, this is not the best time of year for your air conditioner to breakdown, but it does happen. A common area in which breakdowns occur is the indoor unit, also known as the blower or air handler. This unit houses a fan and the evaporator coils, and is responsible for blowing the cool air into your home. Different problems can affect the components in the blower as we’ll outline below, but all can lead to air conditioning repairs in your home.

Fan Issues

The fan in your blower can experience a few different problems:

  • Motor issues – motor can overheat or burnout
  • Electrical/wiring issues – wires and connections can corrode and fray, which may impair connections and delivery of electricity
  • Problems with loose or bent fan blades – fan blades can bend, loosen or break, which may interfere with other parts of your system

Any of the above problems can cause your blower’s fan to either slow down or stop turning completely. The result is low/no airflow in your system, which can cause warm air to blow through your air conditioner vents, or none at all.


Air flow, as mentioned above, is very important in the operation of your air conditioning system. One of the biggest culprits of air flow obstruction is a dirty air filter. The air filter constantly collects the dirt and dust in your system, so it can become dirty rather quickly. Once the filter is fully suffused with both kinds of particles, it can no longer filter and can obstruct the air going into your system. Low air flow can lead to warm air, icing and other problems.

Dirty Coils

The evaporator coils can gather dust and dirt, and if not cleaned at least once a year, these particles can form a layer that acts as insulation on the coils, inhibiting the heat release and cooling cycle. This can result in warm air and/or ice formation on the coils.

Don’t Blow Up Over Your Blower

Many of the issues we’ve outlined above are addressed during a routine maintenance appointment, so scheduling annual maintenance can go a long way toward preventing these kinds of issues from developing. However, if you do experience a problem with the blower of your system, be sure to call John’s Refrigeration for air conditioning repair service in Mesa, AZ. We’ve been helping customers with their air conditioning since 1970, and we understand how important it is to fix your blower quickly and correctly. Call us today!

How to Improve Your Air Conditioner’s Efficiency

June 27th, 2014

Air conditioning in Mesa gets tested every summer, as temperatures climb to triple digits and we need our homes to feel cool and comfortable. A lot of us are used to paying higher monthly rates on our energy bills because of this increased use. But while higher bills are inevitable when the mercury rises, are you sure they’re not higher than they need to be? If you know how to improve your air conditioner’s efficiency, you can cut into those pesky bills without skimping on the cool air you need to keep your home comfortable this summer. Besides common-sense tips like dressing in light clothes and setting your thermostat slightly higher than you normally might.

Here Are Some More Extensive Tips to Cutting Those Costs Down

  • Schedule a maintenance session. Maintenance sessions act like a tune-up for your air conditioner. The technician cleans off dust and dirt (which reduces friction and wear), tightens loose bolts (which prevents wasted energy) and recharges refrigerant levels (which will improve efficiency). If further repairs are needed, he or she can note them and set up a schedule before the problem gets out of hand. You’d be surprised home that can improve your system’s performance and cut down on monthly bills.
  • Add insulation. It may sound counter-intuitive, but insulation keeps hot air out in the summer as well as it keeps warm air in in the winter. Adding more will allow your house to retain cool temperatures for longer, easing the burden on your air conditioner and lowering your bills in the process.
  • Add a zone control system. This is a series of vales and controls placed throughout your duct system that lets you alter the temperature in different rooms and even turn off the air conditioner in those parts of the house you aren’t using.

For more ways to improve your air conditioner’s efficiency, or to schedule a repair session for your air conditioning in Mesa, call upon the experts at Johns Refrigeration. We have the skills you need to do the job right, so don’t hesitate to contact us today!

Who invented air conditioning?

June 24th, 2014

While the question of who invented air conditioning isn’t clear, there are many forms of cooling that have been attempted over the years. Many of the earliest forms of air conditioning may more accurately be called early forms of evaporative cooling, also known as swamp cooling. In the desert, this type of cooling is especially effective, as there is not a lot of humidity in the air.


Evaporative cooling may well have been invented by the Romans who used their aqueduct technology to circulate cool water through the walls of their homes. In the 3rd century, Emperor Elagabalus had snow imported to Rome and dumped in the garden next to his villa during the summer as a way to keep cool. Not only was this inefficient, some thought it very un-Roman to not just bear the heat for a few months.

Modern fans blowing through iced cold wet sheets provided evaporative cooling to many who had previously suffered through the heat of the summer, including President James Garfield. Air conditioning remained an amenity for the rich until the 1800s brought it to the middle class.

Who invented air conditioning?

Most often it is credited to Willis Carrier who, in 1902, invented what is known as the first modern air conditioner in Brooklyn, NY. It was created for a publishing company to keep humidity low so the paper didn’t expand and contract. It was never intended to be used solely for comfort, as we use air conditioning today.

In 1925, Willis Carrier introduced a revised version of his original invention to the public at the Rivoli Theater in Times Square, New York City. People piled in to cool movie theaters for years for relief from the heat. Little did Carrier know the role he played in creating the summer blockbuster movies we know today!

The next time you are too cold in the summer, give a thank you to Willis Carrier, the inventor of the modern air conditioner.


How to Tell It’s Time to Upgrade My Air Conditioning

June 23rd, 2014

Few appliances have more importance for a home in Tempe than a powerful and effective air conditioner. We can experience warm temperatures even during the winter, and the summers soar above 110°F regularly. If your air conditioning system in Tempe, AZ has started to approach to the end of its service life, you need to know the signs so you can arrange for a replacement before the system either becomes too expensive to operate or it breaks down permanently during one of the hottest stretches of the summer.

Here are a few signs of impending air conditioner replacement that our team at Johns Refrigeration would like to share with you. We are here to help with a professional opinion if you are unsure if it’s time to install a new AC. If you are ready for a new cooling system, we will use our more than 40 years of experience to help you find the right replacement and install it so it will provide you with many years of cool summers (and winters, springs, falls, etc.).

Watch For These Warnings That You Need To Upgrade Your AC

  • Excessive age: The manufacturer of your air conditioner set an estimated lifespan for the system. Although it’s possible to exceed this number with the proper maintenance care, you should still give serious consideration to replacing the unit if it has gone a few years past this. The chance of the system starting to decline and waste money increases with each year past this estimate—it’s safer to get ahead of these problems.
  • Extremely noisy operation: An AC that makes constant clanging, grinding, and groaning sounds has probably aged past the point where it can efficiently do its job; the components are too worn down to work well. A single unusual noise can mean a problem a targeted repair can fix. But with an older system, constant sounds are a sign of an impending breakdown… unless you replace the system first.
  • Elevated utility bills (with no relief in sight): When your electrical bills start to rise while the AC regularly operates, than the system has probably permanently lost its efficiency. If maintenance and repairs do nothing to stop the rise of electrical costs, than the air conditioner is no longer worth keeping, and it’s time to arrange for a new installation.

Call for the AC Professionals

Making the choice to replace a cooling system is a large one, but in many cases it’s the most economical and cautious one. Call Johns Refrigeration for help making this choice, as well as for the expert installation for your new air conditioning in Tempe, AZ if that ends up as the best decision for your comfort and your budget.
