What Is the Best Ductwork Material You Can Use in Your Home?

Your ductwork is the pathway through which heated and cooled air passes and stale indoor air is removed from your home. The many ductwork materials available today may make choosing the right one for your needs seem overwhelming. Let's discuss the best options available to help you better understand where each ductwork material excels and lacks.

Sheet Metal

Sheet metal ducts are made of aluminum or galvanized steel. They're durable due to their thick, solid walls. In fact, they can be stepped on without being crushed. They're available in various duct shapes, including rectangular, round, and spiral oval. The smooth interior traps particles like dust and is easy to clean. As a result, it's advisable to have sheet metal ducts cleaned professionally from time to time.

Fiberboard

Fiberboard is typically the most inexpensive ductwork material to install. Fiberboard ducts comprise resin boards bonded with fiberglass strands. Their outer foil face serves as a barrier against water and air. Their interior is sealed to prevent fiberglass particles and fibers from infiltrating the air. Fiberboard provides soundproofing benefits and can be made to fit spaces where it would be challenging to fit some other materials. Fiberboard ducts are susceptible to mold and mildew growth, particularly in humid climates.

Fiberglass

Fiberglass can be used to line sheet metal ducts internally or externally. The lining limits heat loss and offers insulation from HVAC sounds. Consequently, fiberglass-lined ducts are popularly used in offices. However, mold easily affects them, making cleaning them challenging. Additionally, the fiberglass can deteriorate and release particles into the air, potentially affecting your health.

Flexible

Flexible ducts consist of thick polymer plastic covering a steel, spring coil. They curve easily, making them fit easily in tight spaces. They're the second-cheapest ductwork type, resistant to mold and bacteria, and they're easy to install and maintain. Many people claim to be able to install them, leading to poor installation, air leaks, and inefficiency. Flexible ducts tend to impede airflow, hindering optimal air circulation.

The best ductwork material for your house may depend on factors such as overall design, your budget, and individual preferences. An HVAC professional can help you choose the best material for your home and your area and help you insulate and seal your existing ducts.

Are Ductless HVAC Systems a Good Idea?

Ductless Mini-Split - Tulsa, OK

If you've wondered whether a ductless HVAC system is a good idea for your home, talk to your HVAC consultant and get the lowdown on what is commonly known as the ductless mini-split. Ask your consultant how well this HVAC system is likely to work in our climate. Following are some important facts about this technology so you can better evaluate whether it's for you.

Do Mini Splits Heat and Cool?

Although you can acquire a mini-split that only cools, you might want to look at those with heating capability. A few years ago, mini-splits were not considered as efficient as heating systems in areas where temperatures fell below freezing, but they have been vastly improved in recent years, so they may work well in winter in your home.

Are Mini-Splits Quiet?

Mini splits were once known for being noisy, but no longer. In fact, many homeowners choose them because of the quiet, gentle flow of heated or cooled air that the air handler puts out as compared to the sudden — and noisy — rush of conditioned air from a central system.

Are Ductless HVAC Systems Challenging to Install?

Not really. However, you do need to hire someone with experience and good training in installing mini-splits so yours will work properly and efficiently. In most cases, installing a mini-split is not a DIY job.

Ductless HVAC systems are considered fairly straightforward to install, with an outdoor condenser and a conduit with wires and refrigerant leading to an indoor air handler. The air handlers typically are very versatile when being fitted into the home, with some models designed to be tucked away on a shelf or in a corner. Furthermore, they don't need to be connected to a system of ductwork.

Are Ductless Systems Expensive?

Ductless systems can be considered expensive, costing between $1,500 and $2,000 per ton (12,000 Btu per hour) of cooling capacity. However, they are extremely efficient and can save a homeowner as much as 30% a year on energy bills.

How to Keep the Temperature in Your Home From Fluctuating Too Wildly

While it's expected that outdoor temperatures will fluctuate depending on the weather, fluctuating temperatures inside your home can make it terribly uncomfortable. However, there is something you can do about those temperature swings from room to room. We've put together a list of the top reasons temperatures inside Broken Arrow homes fluctuate so wildly and what to do about it.

Thermostat Issues

If you are like many homeowners, you adjust the thermostat going to and from work and at bedtime to save energy. However, this can result in very uncomfortable temperature fluctuations, especially when you arrive home or wake up to a cool home.

A programmable, Wi-Fi, or smart thermostat is a great solution to fluctuating temperatures, striking a balance between comfort and energy savings. Simply program your comfort and energy-saving settings on your new thermostat and — voila! — problem solved.

Air Leaks and Fluctuating Temperatures

Another common culprit for fluctuating temperatures inside homes is air leaks around windows and doors. You've felt it before: You walk into a room and feel a draft. The reason could be leaky windows and doors.

This cause of fluctuating temperatures is easily remedied by installing caulking of various materials around the leaky windows and doors in your home. For example, rope caulk can be used to seal leaky window frames, and it's easily removed in the spring when you want to let in fresh air.

Ductwork and Fluctuating Temperatures

Evenly distributed airflow is needed in your home to maintain stable temperatures from room to room. However, ductwork issues such as blocked air vents, dirty ducts, and duct leaks often hinder your furnace from heating your home comfortably and evenly.

Make sure air vents are free from obstructions, such as furniture blocking airflow or dust and dirt buildup. If your ductwork hasn't been inspected in quite some time, call your HVAC technician for a preventive maintenance inspection to ensure your furnace and air ducts are operating efficiently. Sometimes, your HVAC system just needs a little TLC to make your home as comfortable as possible.

If you need assistance with fluctuating temperatures, please contact Air Assurance today.

How You Can Maintain Good Airflow in Your Home

Taking a few steps to maintain airflow in your HVAC system supports improved heating and cooling performance, higher energy efficiency and lower costs. Conditioned air circulates through your HVAC system via two separate duct networks: supply ducts and return ducts. As the names imply, supply ducts deliver heated or cooled air to individual rooms while return ducts convey air back to the furnace or air conditioner.

Airflow may be thought of as the lifeblood of your HVAC system. Keeping all system components in good repair, including taking proper steps to maintain airflow, ensures consistent indoor comfort and affordable operation, and it reduces wear and tear on critical parts. Here are some suggestions to regularly maintain airflow and reap the benefits:

Replace the air filter.

Nothing disrupts proper HVAC airflow like a dirty, clogged air filter. During winter heating season, inspect the filter monthly and don’t go longer than two months without replacing it. In summer air-conditioning season, change the filter every month to maintain airflow.

Open all vents.

Don’t close or obstruct HVAC vents in individual rooms. The system generates the same conditioned air volume whether vents in rooms are open or not. Therefore, any savings will be insignificant. Meanwhile, wear and tear on system components as well as monthly operating costs will rise. Also, closing vents unbalances airflow volume to rooms throughout the entire house, resulting in cold spots and overly warm areas.

Schedule a duct inspection.

All the airflow to rooms in your home passes through the system supply and return ductwork. Leakage from ductwork joints and deteriorating duct segments allow conditioned air to escape into unconditioned zones like the crawl space and attic. Maintain airflow by scheduling a duct-leakage test plus a full inspection to accurately determine the rate of leakage and identify needed sealing repairs.

How to Achieve Temperature Balance Between Inside and Outside

When the outdoor temperature gets colder and colder in the Broken Arrow area, it can be hard to get the inside of your home feeling comfortable. How can you maintain the right temperature balance between the outdoors and your home's interior? Keep the following tips in mind so you can have a cozy home without high energy bills this winter.

Check Your Insulation

Your home’s insulation helps keep colder air outside and warmer air inside. Not having enough insulation can cause your heating system to work harder and turn on for longer periods of time. This results in much higher energy usage and higher heating bills as the system strives to achieve temperature balance. Having the right amount of insulation can help you balance outdoor and indoor temperatures so that your home interior won’t get too cold or drafty this season. This can lead to lower energy bills — even when it’s freezing out.

Check Your Ductwork

Your ductwork can have an impact on how warm your home is and how much temperature balance you have in your home. Dents or other duct damage, or ducts that are filled with dust and debris, can make it harder for your home interior to stay evenly heated. Consider having your ductwork inspected and cleaned professionally in order to maintain a balanced temperature indoors when it’s cold out.

Schedule Maintenance

Your heating system won’t be able to heat your home efficiently as it gets colder outside if it’s not in good condition. Schedule HVAC maintenance to ensure that your home can stay comfortable and warm all winter without running up your energy bills. These maintenance visits include inspecting your HVAC equipment, cleaning and tightening components as needed, and checking for problems that could affect your HVAC system’s performance and efficiency.

If you need additional help with temperature balance or maintenance for your heating system this winter, please contact Air Assurance in Broken Arrow. We can help you make sure your home is ready for winter’s freezing outdoor temperatures.

HVAC Ductwork Basics

Consistent temperature control and healthy indoor air quality throughout your home rely on HVAC ductwork basics to get the job done. The blower in a typical residential air handler continuously circulates over 1,000 cubic feet per minute of conditioned air as long as the system is cycled on.

Here are some HVAC ductwork basics that show how the elements work together—and how common problems sometimes arise.

• Residential ductwork is actually two systems: supply ducts and return ducts.

• Supply ducts deliver conditioned air to individual rooms, entering through a supply vent on an upper portion of a wall, close to the ceiling.

• Return ducts remove air and convey it back to the air handler to be cooled or heated again. Some houses have return vents in every room, many others have only one central return vent often located in a central hallway.

• Supply and return air volume in the ductwork system is balanced to ensure neutral air pressure inside each room—the optimum condition for temperature control and air quality.

• Most ductwork is not visible in a typical home. Usually, the long spans are routed through areas such as the attic or crawl space. Shorter “branch” ducts that extend into rooms may be installed inside wall cavities.

• Rigid ducts are usually fabricated of rectangular or round sheet metal. Flexible ducts consist of a wire internal coil covered by plastic.

Potential Duct Problems

As ductwork ages, air leaks may develop at joints and other points in the system. Loss of conditioned air into unconditioned zones such as the crawl space or attic is a major contributor to increased operating costs and poor cooling and heating performance. A professional duct inspection including pressure testing can determine the extent of leakage. Proven sealing techniques will restore leaky ductwork to standards.

Thermal gain or loss frequently affects airflow temperature in ducts routed through very hot or cold zones like the attic or crawl space. Insulating exposed ductwork in these unconditioned zones resolves the issue.

HVAC Tape and How It's Used

Some HVAC projects are costly and typically need a professional to perform them. Fortunately, if you're a do-it-yourselfer, there are some tasks that you can handle on your own with ease. One of the tools that will come in handy when performing such tasks is HVAC tape.

What is HVAC Tape?

HVAC tape refers to any tape that's specifically engineered for HVAC installation and maintenance tasks. For example, you can use the tape to seal flex duct, rigid duct material, and sheet metal.

How Do You Apply It?

How you apply the tape to your HVAC equipment makes the difference between dependable, long-lasting performance and expensive inefficiency. Be sure to follow the steps below:

1. Tear or cut enough tape from the roll if you're sealing a short length of HVAC material. Apply the tape directly from the roll if you're to use it on a longer material. For easy handling, just unroll a few inches of the tape at a go while applying.

2. Starting with the end you're using, remove the tape liner. Apply the HVAC tape while centered over the area you're sealing. Keep peeling off the liner while applying the tape. Make sure the tape stays unwrinkled on smooth surfaces and conforms to textured or uneven surfaces like reflective insulation and flex duct.

3. If you're applying the tape straight off the roll, tear or cut it once you establish the exact length that will ensure no leaks or gaps and total system closure. Using excess tape will unnecessarily increase your repair costs.

4. Finish your tape application by wiping it down thoroughly with a squeegee. That maximizes surface contact, resulting in a more secure bond.

Remember, HVAC tape reliability is crucial to the success of your project. Therefore, only work with a UL listed tape as it has passed a series of tests for shear strength, tensile strength, and adhesion level. If you get stuck and need responsive and reliable HVAC assistance, contact the experts at Air Assurance. We've been helping Broken Arrow homeowners with their home comfort needs since 1985.

How Does Duct Design Affect Heating and Cooling?

If you're asked which of your home's HVAC components are most important, you'd probably say your furnace, air conditioner, or heat pump. Another component that you shouldn't overlook is the duct system that distributes your conditioned air, because it directly affects your heating and cooling equipment's performance.

If the duct design is flawed, the ductwork is poorly installed, or it's damaged or leaky, you can experience problems with:

Temperature control.

Damaged or leaky ductwork that lets conditioned air escape can make it difficult or impossible to maintain your desired comfort level.

Air quality.

Pressure imbalances due to duct design flaws can pull in contaminants and allergens from unconditioned areas and erode your indoor air quality.

Energy consumption.

Overcoming duct deficiencies increases the workload of your HVAC equipment, so it uses more energy.

Component longevity.

That extra workload can also shorten your costly HVAC equipment's lifespan.

Fundamentals of Effective Ductwork Design

A properly-designed duct system should deliver the correct volume of air, at your desired temperature, to the various rooms in your home. Also, it should return stale air back to the HVAC equipment for reconditioning. An effective duct design is based on principles of air distribution and thermal gains and losses, and requires quality materials, construction and installation. Such a system also relies on:

Proper duct sizing.

Individual ducts must be sized to match the capacity of the HVAC equipment. Undersized ducts can't carry a sufficient volume of air, and oversized ducts will reduce the system's efficiency.

Balanced airflow.

To avoid creating positive or negative pressure within the house and HVAC system, the duct system must have the right number of supply and return ducts to deliver an equal volume of air.

Duct location.

Whenever possible, ducts should be placed inside the home's conditioned envelope. If ducts must be routed through unconditioned areas like a garage or attic, they need to be properly sealed and insulated to limit energy losses.

Tight Ductwork: Why it's Important

To keep your HVAC system working at its most efficient level, you must have tight ducts. Leaks in your ducts allow energy loss as heated or cooled air leaves the system before it's delivered where it's needed. Uneven or overly high energy bills are a clear sign of leaking ducts. Here's why it's important to keep your ducts tight, and what you can do if you suspect you have an issue.

Tight Ducts Keep Your Home More Efficient and Comfortable

Tight ductwork is crucial for two reasons. First, it keeps your home more comfortable. Leaky ducts can allow heated or cooled energy to escape before it reaches areas of your home, and this can hurt the overall comfort of your home.Second, ducts that leak allow energy to leave the system, and with it the money you've worked hard for. Leaky ducts make your energy bills higher than they should be.

Signs of Ductwork Leaks

So beyond the discomfort or high energy bills, are there any signs that indicate you have a problem with your ducts? These can be signs of ductwork issues that need to be addressed:

• Rattling noises from the ducts

• Uneven heating and cooling throughout the home

• Loud "swoosh" of air flow

While these may or may not indicate a leak, if you're noticing them, you need to talk to a qualified HVAC professional to ensure you don't have a serious problem brewing.

How to Fix a Leak

Fixing a ductwork leak requires the right knowledge and understandings about how these systems work. Duct tape, unfortunately, is all-too-common of a solution, but one that does little real good. Instead, you need to seal leaks with mastic sealant or a quality metal tape designed for the purpose. However, finding the leaks is not always easy, so it's always best to consult with a qualified HVAC professional.

Of you suspect that you might have a leaky duct problem in your Broken Arrow home, contact the Air Assurance team for an evaluation and workable solution. With tighter ducts, you will enjoy a more comfortable and more efficient home.
