Reduce Indoor Dust and Five More Ways to Make Your Home Healthier

Wednesday, December 3rd, 2014

For about half the year, Phoenix, Arizona homes are closed to keep the air conditioning inside and the hot air outside. While this keeps us cool, it can also wreak havoc on allergies and asthma. Dust, pollen, and other contaminants can get into our homes through leaks in the duct system and unsealed doors and windows. Reduce indoor dust and you can reduce the allergies and asthma symptoms associated with unclean indoor air.


The team at John’s Refrigeration will come to your home and perform a whole home inspection to see where allergens are getting into your home and offer solutions such as a whole home air purifier, air humidifier, and sizing and sealing of the duct system.

Other ways to make your home healthier include:

  1. Carpets. Dust and other particles can get trapped in the carpets of your home, causing allergic and asthmatic reactions. The best option is to get rid of them and replace with tile or hardwood floors, especially in common areas. If you can’t do that, have carpets cleaned on a regular basis; every three to six months is ideal.
  2. Pets. If you have pets, you’re inviting allergens into your home. Dander, dirt, and dust can be causing breathing and other health problems. Before you decide Fido and Fifi have to be re-homed, try bathing them regularly and installing an air purifying system in your home that will trap dander and other allergens before they can make you sick.
  3. Shoes. Take your shoes off as soon as you enter your home. Ask guests to do the same. This will reduce indoor dust, bacteria, and environmental allergens that enter the home.
  4. Pests. No one wants to talk about unwanted house pests, but they are a reality, especially here in the desert. Wash your sheets and other bedding frequently and vacuum the bed to reduce the number of dust mites. If you see cockroaches, call an exterminator immediately. Cockroaches carry bacteria and disease and move as fast as three miles an hour, spreading germs throughout your home.
  5. Mold. Check under sinks and around windows for leaks that can eventually grow mold. As soon as you find mold, get rid of it, as it can cause a variety of breathing and other health problems.

If you’re worried about indoor dust and other allergens in your home, Just Call John’s for an inspection of your HVAC system including the unit and the duct system of the entire home. We’ll help you reduce indoor dust and keep you healthy!

What is the Condensate Pan?

Friday, 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 to Reduce Strain on Your Air Conditioner During a Heat Wave

Friday, 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.

AC Services You May Need During the Summer

Friday, 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

Monday, 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

Friday, 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!

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

Monday, 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.

Why Low Refrigerant is a Problem in Your Air Conditioner

Monday, June 9th, 2014

Your air conditioner relies on refrigerant to do its job: cycling through various valves and coils, and cooling your air in the process. Refrigerant varies by type and needs to be applied in a set amount unique to your specific model of air conditioner in order to function the way it should. When those levels drop – such as when a leak springs up in the system – it can severely affect your system’s performance. The good news is that services that handle air conditioning in Phoenix usually have a lot of experience in sealing leaks and recharging refrigerant levels.

Here’s A Brief Outline on Why Low Refrigerant Is a Problem in Your Air Conditioner

In simplest terms, the lowered refrigerant levels mean that inadequate amount of refrigerant enter the evaporator coils to complete the cooling process. As a result, frost and ice will form on the surface of the coils, which creates three specific problems:

  1. The ice represents lost cooling potential, stuck inside the air conditioner instead of being blown into your home. The more ice you see, the more cool temperatures are being lost instead of going where they need to.
  2. The ice forms an insulating layer between the coolant inside the coils and the air that needs to get cooled. The more it goes on, the harder the system has to work to cool the air, and the more energy it will use in the process.
  3. Melting. When the ice melts, it could damage other sensitive components in the system. Most AC units have a condensate pan to catch condensation from the coils, but the presence of excess ice could cause an overflow, which is a significant problem.

If you understand why low refrigerant is a problem in your air conditioner, you also understand that you need a pro to fix it. Simply scraping the ice off won’t work (and may damage the coils in the process). Here at John’s Refrigeration, we handle all kinds of problems related to air conditioning in Phoenix, and we know how to properly treat low refrigerant levels. Pick up the phone and give us a call today. You’ll be glad you did!

Why Dripping Water Is a Problem With Your Air Conditioner

Thursday, May 8th, 2014

You need a reliable cooling system when summer rolls around, and here in Gilbert, AZ, air conditioning systems are as common as televisions and refrigerators in most homes. It behooves you to check your system for potential problems regularly and more importantly, to understand which signs indicate a need to summon a repair service. Dripping water, for instance, may not seem like a major cause for concern, but it can often indicate a significant issue.

Here’s Why Dripping Water Is a Problem with Your Air Conditioner

Dripping water usually stems from one of two serious issues. The first is a build-up of ice on your evaporator coils, representing lost cooling potential and insulating the refrigerant from the air it is supposed to cool. That’s usually caused by a loss of refrigerant, which needs to be corrected before it can cause even bigger problems.

A second cause can come from problems with the condensate pan, which collets condensation from the system and moves it safely out of your air conditioner. If the line gets clogged or the pan itself is misaligned, the water could overflow and create puddles on the ground.

In both of these situations, the dripping water constitutes a significant threat to the system. Air conditioners utilize a number of electrical components, including the condenser motor and fan motor. Dripping water can short them out, shutting your system off and necessitating some very expensive replacement parts. The good news is that a qualified AC repair technician can usually fix the problems before they get out of hand, either by sealing the leak, recharging the refrigerant, unclogging the drain line or fixing the misaligned pan.

That means, however, that you need to understand why dripping water is a problem with your air conditioner, and respond appropriately when you spot it. Air conditioning repair services in Gilbert, AZ are provided by the cooling experts at Johns Refrigeration. We pride ourselves on efficient service and our trained technicians know how to get to the bottom of any problems quickly. Contact us today to set up a repair appointment. You’ll be glad you did!

Needs Addressed by Commercial Air Conditioning Systems

Wednesday, April 16th, 2014

Air conditioning a commercial space isn’t like cooling down a home. Although commercial air conditioning equipment uses similar technology to those found in private houses, the scale and power required makes them very different from the point of view of installation, maintenance, and repairs.

For a city like Mesa, where summer temperatures range in the mid-90s and the average high for the year is 86°F, proper air conditioning is critical for a work environment. We’ll look at what needs an effective commercial AC addresses in a business. For the assistance you need for commercial air conditioning in Mesa, AZ, contact Johns Refrigeration. We’ve kept the Valley of the Sun cool since 1970.

The necessity of commercial air conditioners

  • Better worker productivity: No matter the sort of business you run, you will have employees. Employees require a comfortable space to do their job, and nothing cuts into their productivity faster than a hot, damp, uncomfortable environment. It’s distracting and causes extra exertion leading to fatigue and mistakes. With the right AC keeping the workplace cool, you’ll have happier and more productive employees.
  • Content customers and clients: For businesses that see an influx of customers or clients, whether you run a store or a firm, it’s important to maintain a comfortable temperature level for them. Shoppers will quickly leave a store that feels too warm, and potential clients will start to connect negative feelings about their comfort with their feelings about the company they wish to hire. Professional air conditioning services will keep the people who support your business happy to keep supporting it.
  • A better bottom line: Having productive employees and content customers will certainly lead to a stronger bottom line for your company. But professionally installed and maintained commercial ACs will help the bottom line in other ways: reduced repair needs and greater energy efficient performance. A poorly installed system, or one that doesn’t receive regular maintenance, will quickly cause problems that will need expensive repairs. It will likely drain power as well and raise your bills. A commercial air conditioning system with professional work will save you money in the long run.

For your commercial air conditioners under 20 tons, look to Johns Refrigeration for installation, repairs, replacement, and maintenance—all done with the quality you expect to keep your company successful. We can handle air conditioning in Mesa, AZ for many types of businesses. (And if you need AC work for your home… well, we can do that too.)
