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…)

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

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.

3 Ways to Ease the Burden on Your Air Conditioner

Monday, June 15th, 2015

Our air conditioners do yeoman work here in Mesa, AZ: keeping our homes cool and comfortable even as the desert temperatures climb into the triple digits. All that work comes with an expectedly high cost, as your air conditioner takes on a big workload and your monthly utility bills spike accordingly. But it doesn’t have to be that way. Beyond common sense techniques to stay cool during the summer, such as hydrating and setting your thermostat a few degrees higher than you normally would, here are 3 ways to ease the burden on your air conditioner, saving you money and reducing the chances of a repair call in the future.(more…)

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.

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…)

Importance of Clean Air Filters

Tuesday, May 26th, 2015

With summer quickly approaching, many of us have already started using our air conditioners. If we haven’t yet, we will be soon. Higher temperatures bring higher utility bills. A very easy way to help keep cooling costs down is to regularly replace or clean your a/c unit’s air filter.

The importance of clean air filters cannot be overstated. Your house needs to be able to breathe in order for the HVAC unit to work efficiently. If the air filter is clogged with dust and other pollutants from your home’s inside air, then your a/c unit is working harder to do its job. Changing your air filter every month is an easy way to keep your unit running the way it’s supposed to. Remembering to replace the air filter, though, can sometimes be a challenge. If you change out the filter when your utility bill comes in the mailbox, that’s an easy way to remember, and it’s more likely to get done.

If you have an electrostatic air filter, then you don’t need to replace it every month; you just need to clean it. Electrostatic air filters create their own electrostatic charge, attracting more particles than traditional, disposable filters, and they are 10 times more efficient than disposable filters. Electrostatic air filters are permanent, washable, and designed with a heavy duty aluminum frame, with two layers of a special polypropylene weave on the front and back, and they contain a unique poly internal lining.

Since these permanent filters clean the air by using static electricity, airborne particles are attracted and held by the static charge until they are released by washing. In order to clean them, simply flush with water in the opposite direction of the air flow arrows, then rinse the other side, drain the excess water, let air dry, and reinstall.

John’s offers a filter service where we bring out a year’s worth of filters so you don’t have to remember to buy them. We also sell electrostatic air filters and can show you how to install and clean them.

Keeping filters clean extends the life of you’re a/c system and helps reduce costs. To find out how John’s can help you with your cooling needs, Just Call John’s.

It saves you money and helps keep your system functioning at its peak. (more…)

5 Tips to Keep Cooling Costs Down

Tuesday, May 19th, 2015

With summer on the way and temperatures already starting to rise, we are all looking for ways to keep our cooling costs as low as possible. It’s a fact of life living in the desert: having an efficiently running a/c unit is a necessity.

 

The US Department of Energy cites that heating and air conditioning your home accounts for almost 50% of the energy use in a typical US home, making it the largest energy expense for most homeowners. In fact, it costs US homeowners $11 billion every year just to run their air conditioners.

Energy efficiency is one of the easiest and most cost effective ways to reduce high energy bills. Here are 5 tips to keep cooling costs down:

  1. Replace your old, inefficient HVAC unit. John’s offers no- to low-interest financing on new a/c units.
  2. Regularly clean or replace your air filters (ideally, once a month) to improve the efficiency and life of your unit. John’s offers a filter service where we bring out a year’s worth of filters so you don’t have to remember to buy them.
  3. Air conditioners make us feel cooler by reducing the amount of moisture in the air. Living in the Arizona desert, though, means we often need to add humidity. John’s can help you determine the right amount so you feel comfortable in your home.
  4. Simply running fans in the rooms where people gather is an inexpensive way to keep cooling costs low. Ceiling fans should be turning in a counterclockwise rotation during the summer. And fans don’t work on empty rooms, so turn fans off (just as you should be doing with lights) when a room is unoccupied.
  5. Shading your home from the brutal sun’s rays is very important to keeping your house cooler. Plant trees on the east, south, and west sides of your house, if possible. Replacing bug screens with shade screens on all your windows help a lot, too.

John’s has NATE–certified technicians that offer you solutions to the many problems homeowners face when dealing with cooling your home. Just Call John’s to find out how we can help you.
