When to Schedule Professional Duct Testing

Monday, November 9th, 2015

Despite being well into November, the heat is still quite intense throughout the day around here. We are certainly still running our air conditioners quite regularly, as we do for most of the year. If your air ducts are not distributing conditioned air throughout your home in an effective and efficient manner, it can prove to be quite problematic in this part of the country. Of course, the fact that your air ducts are largely hidden from view can make it rather difficult to detect problems with them. It’s not as though you can give them a simple visual inspection, over all. If you do suspect that you have a problem with the ductwork in your home, schedule professional duct testing in Tampa, FL with a member of the IERNA’s Heating & Cooling staff.

What Is Duct Testing and Why Is It Important?

Thursday, February 5th, 2015

Before warm or cool air moves into your home from the heating or air conditioning system, it first traverses through a set of ducts that should provide a clear and efficient pathway through which air can travel—in theory. Unfortunately, these ducts aren’t always designed as well as they could be. Sometimes, installation flaws account for air leaks or allow heat to escape or enter the ducts undesirably. But a duct system may also develop leaks over time due to the pressure of the air it contains every day.

Now, don’t think that this is a rare occurrence that only happens in some households. According to the U.S. Department of Energy, most duct systems have major or minor leaks and flaws that account for an estimated 30% heating and cooling loss in the typical home. Any duct system can run into trouble over time, and it’s actually likely that yours is causing some issues of which you are unaware. Thankfully, you can schedule duct testing with a trained professional who can determine whether there are weak points in your ducts, the exact location of leaks, and what should be done about it.

When ducts leak air, it affects multiple areas of your home and your daily life. For one, a leaky duct system keeps you less comfortable. There are likely to be hot and cold spots around the home and your HVAC system will take longer to get the entire home to the right temperature. You’re less likely to notice the difference if the leak has progressed slowly over time (or if it’s always been there), but you may be spending hundreds more on heating and air conditioning every year than you would without any leaks at all. Furthermore, your HVAC system is working way harder than it should have to, which could mean that parts of your HVAC system will fail too soon if your duct system doesn’t receive attention.

Duct testing includes a thorough examination of your ductwork. Testing may include high-tech viewing and recording equipment, air pressure tests, and possibly a look at your HVAC equipment to determine how your ductwork may contribute to irregularities. Experts will then recommend services to correct the problem areas, including duct sealing, repairs, or even a bit of design work.

Types of Problems Discovered During Duct Testing

Monday, November 10th, 2014

Because the ductwork in a home is primarily hidden behind construction material such as drywall and flooring, homeowners are rarely conscious of the condition of their ventilation system. If the integrity of ductwork becomes compromised, however, it will result in serious problems for a home’s HVAC system: a loss of airflow from the vents, insufficient heating and cooling power, increased energy bills, and the infiltration of contamination into the ducts that will then flow into the living spaces.

If you suspect that your ductwork may have damage that requires repairs, the best way to know for certain—and to find out the extent and type of repairs necessary—is to call for professional duct testing. Our indoor air quality team at Ierna’s Heating & Cooling performs duct testing in Riverview, FL and the surrounding areas, and we offer numerous repair services to fix the problems afterwards. Call us today to schedule testing for your ductwork.

What professional duct testing may discover

During duct testing, our team seals up all the registers in your home and then places the entirety of the ventilation system under high air pressure. We then measure the pressure level to see how far it drops and use sensing devices to find places where air is escaping from the ducts. This tells us what is wrong, where it is occurring, and its extent.

One of the most common issues that duct testing uncovers is poor joints and connectors. Sometimes this is the fault of inferior installation work, which is one of the reasons that you should always employ professionals when you need to have new ducts installation or replacements. Custom ductwork design can help make for a more seamless fit during installation.

Poor sealing and broken joints along the ducts are also common problems that duct testing will discover. Another issue that can occur, and is often a problem for a humid place like Florida, is holes developing in the ducts due to corrosion or mold and mildew growth. If this is a problem for your ducts, you will also want to have professional cleaning done or the installation of UV germicidal lights to combat future problems.

Along with providing high quality duct testing in Riverview, FL, Ierna’s Heating & Cooling has full services for indoor air quality that includes duct sealing, custom duct designing, and installation of UV germicidal lights to get rid of mold infiltrations.

When you suspect that your ducts need help, contact us for the testing that will tell you what needs to be done—and let us take it from there.

How Does Duct Testing Work?

Monday, January 20th, 2014

The integrity of the ductwork in your home is an important part of heating and cooling efficiency, and for maintaining high quality indoor air. The ducts that run from your HVAC system to your vents are designed to hold a seal that prevents loss of air pressure and the infiltration of outside air and contaminants. If leaks occur because of breaks or loose connections along the ductwork, you will start to waste money because of the strain on your HVAC system and possibly suffer a decrease in air quality.

However, it’s often hard to know when ducts have developed leaks. For help, you will need experts in professional duct cleaning in Trinity, FL. Ierna’s Heating & Cooling has EPA and NATE-certified specialists in testing ducts to locate places where you may be losing energy—and they have methods of repairing these problems as well.

What Happens During Duct Testing

The purpose of duct testing is to determine the “tightness” of a ductwork system; i.e. how much air pressure it is losing. Once technicians find out how much air pressure is escaping from the ducts, they can investigate the integrity of the system and locate the leaks, then determine the necessary steps to take.

The process requires calibrated mechanical devices to measure the amount of airflow that seeps out of the system at normal pressure. The technicians close all registers and vents and then pressurize the ductwork system. A duct leakage tester, a device made of a calibrated fan and an air-pressure sensor to measure the pressure the fan creates, is used to perform this task. The more air needed to create a change in the ductwork pressure, the more leaks there are in the ductwork.

This test determines total leakage. The technicians will then locate the points where air is found escaping and perform measurements to see what must be done to fix the leak. Some of the leaks will be small, located at joints or seams. In other places, duct sections can have become disconnected entirely.

Depending on the results of the testing, a technician will recommend whether the ducts need sealing, extensive repairs, or perhaps a full replacement.

Proper Duct Sealing and Repair is Important

If you are encountering higher bills for your HVAC system or suffering from a drop in comfort level, you may need to schedule duct testing to see if you require sealing or repairs. Because ductwork already loses around 10%-30% of heating energy under normal operation, leaks can cause a huge drain on your bills.

Contact our duct specialists at Ierna’s Heating & Cooling. We can take care of duct testing, duct repair, and duct cleaning in Trinity, FL to make sure your HVAC system is giving you the best that it can.

Air Conditioning Tip: Benefits of Duct Testing

Tuesday, September 4th, 2012

Over time, the ductwork in your Lutz home can develop a number of problems that can lead to heating and cooling loss, higher energy bills and decreased indoor air quality. Leaks in the ductwork, dust build up, or foreign objects can all be issues in duct systems. One of the most effective ways to ensure these things don’t become an issue in your home is to have regular duct testing performed on your system.

How Duct Testing Works

Duct testing involves pressurizing your duct system and checking for variations in air flow that indicate a leak or gap in the system. This is a relatively simple process and can be completed in a couple of hours to determine where your ductwork might be costing you money. Generally, this type of testing does not need to be performed as often as other preventive maintenance tasks, but if it has been a while or if you suspect a leak has developed, it can be an effective way to test for such problems.

 The Benefits of Duct Testing

When performed regularly, duct testing offers a number of benefits. To start, duct testing will pinpoint possible air leaks immediately, before they can grow and cause a large loss of heating or cooling capacity.

At first your system will compensate for such loss, but with time it can cause a degradation of your heating or cooling system that will lead to excess repairs and early replacement. If this happens, you may lose heating and cooling, and at the very least, you will need to pay for repairs.

Duct testing can also ensure optimal air quality in your home by closing up any leaks that allow in things like exhaust and outside allergens. In older homes, duct testing may even find signs that your ductwork needs to be replaced.

Whether you have noticed a drop in heating and cooling efficiency or your Lutz home is just not as comfortable as it once was, consider adding duct testing to your regular maintenance schedule. Call Ierna’s Heating & Cooling today for duct testing and AC service in Lutz  and the surrounding area!
