Ductwork Transforming

Don’t Force Your HVAC System To Run In Place

We can easily compare leaky ducts in your HVAC system with the human body. Imagine that you are doing everything to get to the place you want, but it feels like you aren’t doing anything.

Let’s look deeper at the situation. The equipment starts working to keep desirable level of comfort inside the house, and the fan turns on and starts to circulate the airflow. When the fan gains the speed, which is needed, leaky return ducts start to suck in air from our cold basement or hot attic or crawl space. Instead of dealing with air, which returns from our house at the level of temperature, which is indoors, the system provides unconditioned air that’s much colder or hotter. Our air conditioner or furnace has to work above the standard to turn this airflow into the air of the right level of temperature.

aThe Efficiency Of Energy In Your HVAC System Is Lowered By The Gaps In Ductwork.

We understand that it is not good, but we will tell you much more. At this moment we do not have warm enough or cold enough air, which travels down the supply system of ducts, and the leaks in supply ducts let some of this airflow (remember, that we have already overpaid to cool or heat it) leak out instead of pushing it inside the house. As a result, the system has to be bigger and work longer and we have uncontrolled “bad air”, which leaks into the home. You might have an allergy, and your home will be dusty and dirty after a few days after the cleaning. So now you realize that ducts are very important for the working process of the whole HVAC system.

Balance Of Supply And Return Air Ducts

What Comes In (have to be equal to) = What Comes Out. The level of efficiency of HVAC working process depends on balanced airflow. The volume of air, which is returned by the system from your house, should be equal to the volume of air, which is supplied by the system inside it. If they are not equal, there is an imbalance of an air pressure. Negative pressure inside the house can redo the activities of the vacuum. It pulls air inside the house from outside or from “bad” channels like attic or a crawl space. Imbalanced airflow can make you rooms drafty or uncomfortable as a result.
“Duct blaster” – is a kind of test operation, which can measure energy-wasting leakage of duct.

First Step – Diagnosis Of Duct Problems, Second Step – Solving Problems

The duct leakage and other duct problems are hard to detect, so you should have the right tools and good diagnostic skills. As soon as Fox services checks your ductwork system, the processes of loosing energy and wasting money will be instantly showed to you. If your ductwork system causes pressure imbalances, which can result in leaking of the outside air inside your home – you will also see it.

Strategies Of Sound Sealing – Caulking, Foaming And Sealing

Leak sealing goes after the detection of leak. The best sealing plan for your ductwork depends not only on the type of ductwork, but also on the availability of the leaking ducts. Only special tools, right materials and professional techniques are required to do sealing job  effectively and it is good way to improve your comfort and quality of the indoor air and also cut your paying bills!

Only a charlatan would use duct tape on duct system

qLeak Sealing Goes After The Detection Of Leak.

You can use duct tape almost everywhere, but you shouldn’t use it on ductwork. This tape was originally developed during World War II. Its mission was to keep moisture out of ammunition cases. Servicemen appreciated waterproof qualities of this tape and due to the fact that the cloth backing was made from cotton duck cloth, so it was named “duck tape”. But the war ended, and the duck tape turn into “duct tape”, when contractors start to use it for sealing ductwork. But after some period of time it was found out that if you use such tape on ductwork, it  dries out and disintegrates. Its effectiveness of sealing doesn’t last very long. So, the result of the story is that duct tape is useful to keep around, but you should not use it to seal the leaky ducts.

Air Ducts Need Insulation Too!

If your air ducts are not adequately insulated, the conditioned air that you paid to cool or heat goes through the duct system with little or even without protection against extreme temperature of airflow. You know, that the duct system is made of a sheet metal. So, how it will act in a sweltering attic during hot summer weather? It is obvious, that cool conditioned air will become warm  enough as it goes through hot duct. And the heated air, which runs through ducts in a freezing crawlspace, will not be as warm as it is needed. It will just cool down as it goes through freezing ductwork. Such losses of energy can really add up fast, and they do not have a positive influence on the level of comfort and the efficiency of energy.

If you add insulation, you will reduce losses of energy in duct working processes. Fox services will quickly find the best type of insulation for your duct system and the right levels of insulation to use to make your ducts work better and maximize your home energy saving.

Duct system and leakage of ducts – how to test and evaluate

Better Air Care

Usually the temperature in duct system is cool or hot. If you use forced-air heating, central air conditioning, or both, your home uses a ductwork, which is distributing conditioned (cooled or heated) airflow throughout your home. The supply ducts “blow” conditioned air to different areas, while return ducts push air back to the furnace or air-conditioning device so that this air can be cooled or heated and then distributed one more time. This cycle goes on until your  thermostat shows your furnace or AC device that the needed level of temperature has been reached.

Question Of The Day: Difference Of Sound Duct System

When you do energy checkup of your house it is important remember testing and evaluation of the ductwork system. The critical decision in any cooling and heating (HVAC) system is properly sized and installed ductwork. But, ductwork system is often overlooked when evaluating your home energy performance, despite its importance. It may result in bad things.

Let’s have an example:


Leaky supply ducts let air you’ve already paid to cool or heat “leak away” before it goes inside your house. Leaky return ducts allow unconditioned airflow from your basement, attic, or crawlspace to “trap into” your system. In both situations, the air that reaches your living rooms is not as cool or warm as it is needed, so you don’t get the desirable level of comfort.

Efficiency Of Energy

If conditioned air goes away before it reaches your living rooms, it is obvious that you don’t get that, what you paid for. If air from your cool basement or warm attic or crawlspace gets into your system, it takes more energy (and increase your paying bills) to either warm it up or cool it down to make it usable for conditioning your house. In fact, you could be heating or cooling the great amount of outdoor air without even realizing this fact!

Quality Of Indoor Air

If you have return duct leaks, you could be receiving “not good airflow” directly in your home whenever your equipment works. You definitely wouldn’t like to breathe crawl space or attic air every time, but if you have this uncontrolled leaks, you might force to do it! Leakage of ducts also causes problems with the quality of indoor air. The reason is in “imbalances of pressure”, which put some spaces under negative pressure and other rooms under positive pressure. This can result in bad airflow (full of allergens, dust, dirt, pollen, and other harmful elements) to be pushed inside your house.


Leaky duct causes pressure imbalances, which can result in backdrafting in units of combustion, for example wood stoves, furnaces and gas ranges. If this situation happens, you can get under the influence of CO, which is fatal composite.

Leaky dust provides wasting of almost 40 percents of an HVAC system’s energy consumption. So that, when you do energy checkup of your house it is important remember testing and evaluation of the ductwork system.

New Units, Old Troubles
