3 Common Problems with Thermostats

Monday, July 20th, 2015

If you live in Mesa, AZ, chances are you're very familiar with your thermostat, especially during those summer months when the temperatures soar. Your thermostat provides absolute control over your heating and air conditioning system. That means that when something goes wrong it with, it can affect your entire home. The good news is that those problems can be fixed by a trained technician. The bad news is that you have to be able to spot the problems first. Here are 3 common issues with thermostats that you should look out for. (more…)

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…)

Ways to Save Energy You Might Not Have Heard Before

Tuesday, June 30th, 2015

Ways to Save Energy

Summer is quickly approaching. Here in the Arizona desert, that means higher utility bills as we try to keep our homes cool enough to keep us comfortable. We all know that setting the thermostat a few degrees higher helps reduce the energy costs we all face. Replacing your thermostat with a programmable thermostat can save you even more. Sealing and caulking around windows and doors is among the easiest and least expensive ways to keep the cool air in our home instead of cooling the outdoors. But here are a few ways to save energy you might not have heard before:

  • Turn off kitchen and bath exhaust fans. Use them while taking a shower and cooking, but remember to turn them off afterwards.
  • Block the sun from entering your home by using shades, blinds and drapes.
  • Plant trees to provide shade on the outside of your home or use awnings to keep the sun from heating your home.
  • Open interior doors so that air conditioned air flows freely throughout your home.

Also, SRP offers free shade tree planting workshops where you receive two free shade trees. They detail how and where to plant for the best results and also make sure you know how to take care of the trees so they continue to shade your home for many years. Trees also often increase a home's value as part of the curb appeal and landscaping of your property.

No one wants high utility bills. Doing what you can to save you money doesn't mean you have to figure it all out yourself. Just Call John's to see how we can help save you energy and keep your hard earned money in your pocket.

What Happens When Refrigerant Leaks?

Monday, June 29th, 2015

Refrigerant leaks and low refrigerant levels rank among the most common reasons to summon an air conditioning technician. Theoretically, your air conditioner runs its refrigerant through a closed loop: shifting it from a gas to a liquid and then back into a gas, and pulling heat from the nearby air in the process. That depends on precise levels of refrigerant in your system (the exact amount depends on the system) and when it springs leaks, it can have a detrimental effect on your ability to cool the air. Here in Mesa, AZ, that's a significant concern, especially in the height of summer. So what happens when refrigerant leaks? Nothing good. (more…)

Three Main Parts of a Cooling System

Thursday, June 18th, 2015

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!

How Do Zone Control Systems Work?

Monday, June 1st, 2015

Here in Mesa, AZ, we need our air conditioners to function as effectively as they possibly can. With proper maintenance, your centralized system should be able to do an effective job, but even then, you can expect to pay higher bills every summer as our triple-digit temperatures put it to the test. Luckily, it doesn't have to be that way. A properly installed zone control system added to your existing air conditioner can perform wonders for your monthly cooling bills, as well as providing an unprecedented level of precision and control. How do zone control systems work? Read on for the answers. (more…)

3 Signs of Trouble With Your Air Conditioning

Monday, May 11th, 2015

Mesa, AZ gets as hot as anywhere in the world during summer, and the last thing you need when the temperature shoot past 100°F is an air conditioner that breaks down. The sooner you can spot a problem with your system, the more quickly it can be addressed and less chance of serious trouble when the heat starts to rise.


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.
