Beware of Formicary Corrosion

Monday, November 23rd, 2015

Heaters and air conditioning systems have become more effective and efficient as time goes on, which has become a great boon out here in Mesa, AZ. But that often creates new challenges and even new dangers which can cause your system no end of trouble. Among them is the recent rise in formicary corrosion, which strikes at the copper tubing in your heating and air conditioning system, and is responsible for trouble like refrigerant leaks and even the full-bore failure of the tubing. A good technician can correct the problems caused by formicary corrosion and help your indoor air quality to boot. Let's take a look at how it all works. (more…)

The Best Way To Clean A/C Coils

You may have heard the commercial on the radio about how they clean coils. Interesting topic. Maybe you've had another air conditioning company tell you that you need your coils professionally cleaned and then watched as they proceeded to wash the outside unit down with a hose. You could have done that yourself! But DON'T DO IT! Maybe they spray your unit with an acid that will shorten the life of your system.Neither way is good. There is a proper way to clean a/c coils and we know how to do it the right way. (more…)

Get Your AC Ready for Winter

Monday, September 14th, 2015

We use the term “winter” loosely here in Mesa, AZ. Temperatures stay warm year-round, and while we have our share of chilly nights, you'll probably need to call upon your air conditioning more than once before next summer comes in. That's why getting your AC ready for winter is so important. It means you'll never be caught flat-footed by an unexpected heat wave, and even if you don't need to use it in the next few months, it will be ready to go in the spring. (more…)

Ductless Air Conditioning

Tuesday, July 28th, 2015

Ductless air conditioning involves the installation of an outdoor and indoor unit, similar to a central air conditioner system. But where central air conditioning uses a fan to distribute air through the ducts, ductless systems contain all of the indoor components in an air handler mounted high on the wall or on the ceiling. These air handlers blow cool air directly into the room, which is why most homes require more than one air handler. One outdoor condenser unit can usually accommodate up to four indoor air handlers, though. However, you don't necessarily need ductless air conditioning to fix a hot room. Your current ductwork may just need to be repaired or cleaned, which is also a service that John's offers.

If you choose ductless air conditioning, these units deliver cooling evenly throughout your home without having any ductwork. Ductless units are often just as powerful as central a/c systems. In fact, many traditional HVAC systems that use air ducts can't perform as well due to leaks in the ductwork. With a ductless unit, you won't have to worry about air leaks, which means you'll be more comfortable and enjoy lower utility bills because of the energy savings.

When you use ductless air conditioning to cool your entire home, you also have zone control, which isn't an option with a ducted system. Each air handler has its own thermostat, which means that you get to choose the temperature in any zone of the house separately from the other areas. So if you need the bedrooms to be cooler at night, but the kitchen and living areas to be cooler during the daytime, all you have to do is adjust the temperature in those zones.

If you'd like to learn more about ductless air conditioning, Just Call John's. We offer ductless service, as well as duct repair and inspection for homes that have ductwork.

The Principles of Good Duct Design

Tuesday, July 21st, 2015

According to the U.S. Department of Energy, poorly designed air duct systems can lose as much as 40% of the heating or cooling energy passing through them. A poorly designed air duct system makes it impossible for an HVAC system to run at its optimal efficiency. HVAC systems are responsible for almost 50% of the energy expenses in a typical home, and the ductwork plays a significant role.

The design and efficiency of your home's ductwork contributes to utility bills, air quality, and comfort, as well as efficiency and wear on the system. Ductwork provides the channel through which cooled and heated air travel. Restricting that air flow because of poor duct design is detrimental in so many ways.

Good duct design increases the efficiency of air flow, making it easier for your HVAC unit to cool down or heat up your home so you're more comfortable. Sometimes ductwork is located in places where the air contains pollutants like dust and mold. If ductwork isn't sealed well, those pollutants may be sucked into leaky ducts and delivered throughout the house. Since air leaks are one of the main cause of energy loss in ductwork, making sure all air ducts are well sealed and connected properly is important.

Leaks in ductwork provide a way for dust, allergens, debris, and pests to get into the ductwork. This will negatively affect indoor air quality and can cause airflow obstructions that contribute to energy loss, making your utility bills climb. Restricted air ducts will also add to the wear and tear on your HVAC equipment.

Just Call John's and schedule an appointment to have your ducts inspected by one of our NATE Certified technicians as part of your annual HVAC maintenance so they remain clean, sealed, and insulated for optimal efficiency. John's offers air duct inspections and cleaningso you can be comfortable all year round. We also offer our Peak Performance Club so you can rest assured that your a/c unit won't konk out in the middle of summer.

Air Ducts

Tuesday, July 14th, 2015

Our homes breathe, believe it or not. And our HVAC systems help control that process. How do air ducts figure into this equation, though?

Dirty air ducts cause the HVAC equipment to work harder and less efficiently. Having your ductwork inspected can mean you'll have improvement in air quality and less dust inside your home. Clean air ducts help the entire HVAC system worked more efficiently. A full cleaning of the air ducts in your home can yield long-term energy savings, but hiring certified professionals to do the job is vital. In fact, a poor cleaning job is worse than no cleaning at all, as it can kick up harmful particles or even break portions of the HVAC system.

Air duct cleaning should involve a thorough cleaning of the air handler, registers, grilles, fans, motors, housings, and coils of the HVAC system, not just the ductwork. John's NATE Certified technicians will also perform an inspection of the ductwork and let you know if there are any problems that need to be addressed.

If you're not sure if you need to have your air ducts cleaned or inspected, here are some key questions to ask yourself:

  • Have you renovated your home in the past few years? Ducts should be sealed off during remodeling projects, so if they weren't, dust and debris may have become lodged inside the ductwork. Or the air ducts could have been moved, causing them to leak airflow.
  • Could there be animals in your air ducts? There may be evidence of animal infestation or nesting in your air ducts or HVAC system, which can greatly affect the air quality in your home. Whether those animals are living in your ductwork or have died, they don't belong there.
  • Do you see mold on your vents? If there is visible mold growth on your vents or inside the ductwork, the air quality in your home has been compromised and is likely affecting the respiratory health of everyone who breathes the air in your home.
  • Have you noticed pet hair, odors, or dust being released into the room through the vents? Once again, these are signs that your air ducts need to be inspected and possibly cleaned.
  • Does anyone in your family suffer from allergy or other respiratory-related illnesses? If so, you may want to consider having your air ducts cleaned to see if the HVAC system is the reason.

People often report using their air conditioner less in the summer after having their air ducts cleaned because of the improved airflow. That means less money paid to the utility company and more money in your wallet. Plus, your family will be more comfortable and breathe easier. Just Call John's to see how we can help you with air duct inspections and cleaning.

What's Involved in Air Conditioning Maintenance?

Monday, July 6th, 2015

Here in Mesa, AZ, you need every advantage you can get to stay ahead of our staggering triple-digit summer heat. Your air conditioner stands on the front line of that battle, ensuring that your house is cool and comfortable no matter how hot it gets outside. But that comfort is only as reliable as your air conditioner itself, and if an unexpected breakdown occurs, you could be in big trouble. That's why an annual or semi-annual maintenance session is so important. Not only does it help you identify potential problems when they're still small and easily treated, but it can improve your system's efficiency, allowing it to do its job without costing you an arm and a leg in monthly bills. What's involved in air conditioning maintenance? Here's a quick breakdown. (more…)

Three Main Parts of a Cooling System

Three Main Parts of a Cooling System

When all the parts of your home's HVAC system are functioning correctly, the system is more efficient, which uses less power, thereby saving you money on your utility bills. It's important for homeowners to keep up with regular maintenance on their HVAC systems to keep them functioning optimally. Understanding the parts of the cooling system is important so you know how the whole system works. Here are the three main parts of a cooling system:

  1. The heat exchanger is located in the HVAC unit. Air is sucked into the heat exchanger and then is quickly heated and blown out through the ducts to be circulated through the house.
  2. The evaporator coils are activated every time cool air is needed. The cooled air is picked up by the furnace blower and forced along the ducts and out through the vents. Evaporator coils are connected to the HVAC system's condensing unit.
  3. The condensing unit is installed outside the home and refrigerant gas is cooled through the exchange of heat with the air outside. Then, it's compressed and condensed into liquid form and sent through a metal tube to the evaporator coil. Once the liquid reaches the coil, a series of small nozzles spray the liquid, lowering its pressure, causing it to turn back into gas. During the evaporation process, heat is absorbed, which causes a drop in temperature and supplies cold air that will be blown through the home.

Ductwork is important, too, since it carries warmed or cooled air throughout the house to all the rooms in your house, where it exits through vents. Loose ductwork can mean dirty air is being circulated through your home. There are many parts to your heating and cooling system that work together so that you are able to enjoy your home in the temperature you choose. Just Call John's if you'd like us to take a look at your cooling system to see if it's running as efficiently as possible.

Peak Performance Club Benefits

Tuesday, June 9th, 2015

Preventing your air conditioning unit from breaking down can save you hundreds, if not thousands of dollars in repair costs or to replace your unit. John's offers an annual a/c maintenance membership that allows you to know you will be comfortable in your home all year long. By giving your HVAC unit some preventive TLC, you can rest assured it's not going to break down when our desert temperatures start heating up to 110+ degrees. Joining our Peak Performance Club also means your unit will last longer and the service keeps it running no matter what the temperature outside is.

When our NATE Certified technicians come out to inspect your unit, we don't just check to make sure it's running, we can also identify safety and health issues. A few of the Peak Performance Club Annual Maintenance Membership features include:

  • Two 51–point inspections
  • Clean indoor and outdoor coils, which maintains proper airflow and prevents issues to compressor valves.
  • Clear condensate to prevent mold formation and avoid water damage.
  • Priority service: You receive service first and ahead of non–club members (very important if your a/c stops working during monsoon).
  • Improved efficiency, which saves you money on your utility bills.

Although the cost of the annual membership is only $199.95, the actual value of this service is $574. You can think of the investment as only $17 a month.

Now that it's already heating up outside, it's also important to remember that houses breathe, so doors and vents should be kept open. Shutting interior doors and closing vents in unused rooms doesn't allow your home to breathe the way it needs to for optimal efficiency.

If you'd like more tips on keeping cool this summer or would like to join our Peak Performance Club, Just Call John's!

3 Reasons to Schedule Spring Air Conditioning Maintenance

Monday, April 6th, 2015

If you've lived in Arizona for a year or more, you know how blistering hot it grows during the summer. Many of the other parts of the year can reach extremely high temperatures, but summer is the season when we need to be the most mindful of our air conditioning systems. If you head into the hottest time of the year with an AC that isn't adequately prepared, it can mean serious trouble. The best way to know that you are ready for the season is to schedule regular air conditioning maintenance from professionals in the spring. Experienced air conditioning technicians will see that your cooling system is tuned-up, adjusted, and any necessary repairs taken care of before the serious heat begins.

To schedule maintenance with Mesa, AZ cooling professionals, call Johns Refrigeration today. We have served the area with superb air conditioning service since 1970.

These are 3 reasons you should always arrange for spring AC maintenance:

  • Avoid surprise breakdowns: The strain of an Arizona summer can push an AC to it limits, and if a system hasn't received regular attention to reduce wear and tear, the heavy heat may cause it to break down—the last thing you want to happen during one of the hottest days of the year! Maintenance technicians will clean and adjust the air conditioner and catch any potential repair issues to make sure there is little chance the system will abruptly collapse during the season.
  • Long lifespan: An air conditioner comes with a manufacturer's estimated service life. But unless the AC receives regular maintenance to lower the effects of age, it will probably not reach this goal. To prevent scheduling a premature and expensive replacement of your air conditioning system, make sure professionals inspect it and tune it up once a year.
  • Maintain energy efficiency: Each year that an AC goes without routine maintenance, it will start to lose energy efficiency and cost more to run. It only takes a few years for a high efficiency 16 SEER system to plummet down to an inefficient 12 SEER system, which will lead to a significant increase in your cooling bills. If you have annual maintenance, you can expect the AC to retain 95% of its energy efficiency through most of its (long) life.

Johns Refrigeration offers an excellent maintenance program to take care of your air conditioner in Mesa, AZ this spring—and every spring after it.

Our Peak Performance Club provides you with two 51-point inspections per year, one for your heater and one for your air conditioner. Membership also provides you with other benefits: call us today to find out more.
