Now is the ideal time to perform a heating maintenance session, in which a technician performs a number of little repairs and corrections designed to keep your system functioning at its peak. Why should you do it in the summer, when you don’t actually need your heater? Here are 3 good reasons. Continue Reading

The Principles of Good Duct Design

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.

3 Common Problems with Thermostats

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. Continue Reading

Air Ducts

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.

How Do Humidifiers Work?

July 13th, 2015

Mesa, AZ is a desert community, which means our air is very dry as well as being hot. Air conditioners can help address the temperature, but do very little to increase the humidity of the air. In fact, they can often do more harm than good in that department. As they cool the air, moisture condenses and becomes liquid (much like dew that forms in the early mornings). Your air conditioner safely collects the condensate in a pan and removes it from the system, but the effect is to make the dry air even drier. A whole-house humidifier can be the answer, and understanding how these systems work is key to explaining their benefits to you. Continue Reading

What’s Involved in Air Conditioning Maintenance?

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. Continue Reading

Ways to Save Energy You Might Not Have Heard Before

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?

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. Continue Reading

Is replacing your windows worth it?

June 23rd, 2015

When it comes to keeping your home cool, maintaining your home’s HVAC unit is key. An efficient unit will not only help keep your home cool and comfortable, but it can also help keep the dust out of your home, which means your home will be cleaner. Less dust also is directly related to fewer respiratory illnesses like asthma, but also annoying conditions like dry skin and bloody noses. For a/c savings, though, can replacing your windows also save you big bucks?

Most windows can actually be compared to having a giant hole in your home’s insulation. Especially if they are older, drafty windows. But new windows are expensive and installing them often costs just as much as the windows themselves. New windows aren’t the best cure for reducing your utility bills. There are easier and cheaper projects you can do, such as sealing all your home’s air leaks, which will have a bigger impact.

The energy savings from new windows don’t usually come even close to justifying their cost. And research shows that the payback period for replacement windows can be as high as 100 years. The new high-efficiency windows might offer twice the insulation value as the old single-pane windows you currently have. Which means new windows would cut your energy loss through the windows by as much as 50%. But some studies reveal only about 30% of your house’s heating and air conditioning disappears out the windows.

Before deciding to replace your windows for a/c savings, Just Call John’s to see what we can do to help you reduce your utility bills. John’s doesn’t just repair and replace HVAC units, we also offer a service that replaces the screens on your windows. We have thermostats that you can control even when you’re not at home. Check out one of our recent appearances on Sonoran Living Live where owner Andrew John talks about some of the options available for a/c savings.
