Insure Your Furnace with an Extra Hot Surface Igniter

Silicon carbide igniters, commonly known as hot surface igniters, are an electrical component that is used in most new gas furnaces. Hot surface igniters are much like the filament of a light bulb, each time the furnace turns on, an electric charge is sent to the hot surface igniter reaching a searing temperature of roughly 2156OF-2426OF to ignite the gas burners of your furnace.

Life Expectancy of a Hot Surface Igniter

Under normal operating conditions, a hot surface igniter will last 3-5 years. During the heating season, the hot surface igniter can go through a tremendous amount of use. Furnaces cycle throughout a day to bring the home to the desired temperature set by your thermostat, hot surface igniters are energized through each furnace cycle. Most high efficient furnaces will cycle 3 times per hour whereas lower efficient furnaces can cycle as many as 6+ times per hour. In a year your hot surface igniter could be energized as over 20,000 times! Over time, through continued use, the filament of the hot surface igniter becomes brittle, and eventually breaks usually when you need it most.

Keep an Extra Hot Surface Igniter On Hand

Much better to have a hot surface igniter and not need one, than to need a hot surface igniter and not have one. There are numerous brands and models of furnaces, technology is changing every day. If you have an older furnace, it may take a while for a furnace contractor to locate a hot surface igniter specific to your furnace. Purchase an extra hot surface igniter for your specific brand and model of furnace to store at home it’s a great insurance policy for a time of need.

Maintain Your Furnace, Filter and Air Ducts

While there is a standard life expectancy of a hot surface igniter, routinely maintaining your furnace through an HVAC company, changing your furnace filters, and keeping your air ducts clean will extend the life of your hot surface igniter as well as other furnace components.

KBPI Christmas Wish | Stacy’s Grandmas House

It all started with a contest: The rules were pretty simple: Tell us what your asking for this holiday season, and why… for a chance to have your wish granted.

One listener… Stacy, asks for a gift of getting her Grandmas house carpets replaced. Willie B DJ of KBPI publicized her selfless request, and calls poured in from contractors of numerous trades transforming the request of carpet replacement to a full blown home makeover.

Ductworks met Brett, owner of CQL 2000 a General Contractor who donated his services. At the time of our arrival there were already over twenty trades at the home. We performed the walk through, to discuss the various projects that desperately needed to be completed. We began with a general meeting, discussing the various projects that would take place, and the high level of coordination it would take for numerous trades working within a confined space.

There was a catch… All of the work to be performed was a surprise to the Grandmother. The grandchildren told the Grandmother that they were going to have the carpets replaced as a Christmas gift, and asked that she stay in a hotel as the work was being performed. All of the work needed to be complete within 4 days!

Within minutes the meeting ended, and all of the contractors formed various bucket lines within the home to remove the homes contents to make space for the various projects that would be undertaken. Within an hour the garage door, furnace and air conditioner were replaced. Ductworks will provided the air duct cleaning at the end of the project once the dust settles.

Willie B of KBPI brought a community of good natured contractors to really show what this holiday is about.

If you could wish for anything you wanted on your wish list this holiday season what would it be?

NADCA Energy Research Project

Fouled Coil: This photo shows the upstream side of a heavily fouled A-Coil, which is essentially matted over with dust and other contaminants.

Heating, ventilation and air conditioning a home or small commercial building is a big job that requires a lot of energy. In fact, this activity accounts for 30 percent of the energy used in an average home or small building. In addition, heating and cooling larger buildings is an even tougher job and accounts for up to half of the energy use in such buildings. On the whole, heating, ventilation and air conditioning systems are by far the largest sources of energy use within a home or building. Ironically, heating and cooling systems tend to be poorly maintained. These systems, which are used every day of the year, get dirty and can become heavily contaminated with dirt, dust, animal dander, and more. Further, heating and cooling systems in new homes and buildings are often heavily fouled – even before occupants move in. Contaminated heating and cooling systems can be problematic for occupants. These systems contribute to poor indoor air quality in the form of increased airborne particulate and reduced thermal comfort. Fouled systems are also prone to failure. And from a cost perspective, these systems also use more energy than clean systems.

The Importance of Air Flow

Dirty Duct: Accumulations of dust and debris within HVAC ductwork can contribute airborne particulate within a home or commercial building, while also reducing air flow and increasing energy consumption and related costs.

When it comes to having a productive, energy-efficient heating and cooling system, air flow is everything. Increased air flow equates to better performance. But when systems become fouled, air flow is reduced. Dirty filters, clogged coils, fouled blowers and other components – all of these things impede air flow and lead to increased energy costs. The solution is to have the heating and air conditioning system professionally cleaned. You may be familiar with the term air duct cleaning, but this is actually a bit of a misnomer. Professional cleaning for a heating and air conditioning system entails cleaning not only the ductwork, but also the vents, registers, blower, coils, and other components – the surfaces that are exposed to the air flow within the system. Complete cleaning of the heating and air conditioning system is a highly specialized cleaning service that differs from the routine maintenance provided by the technician sent out to clean and adjust the furnace. Complete cleaning of the heating and air conditioning system is an important aspect of keeping the system operating at peak efficiency.

The NADCA Energy Savings Research Project

Clogged Air Duct: In extreme cases such as this, ductwork can become totally clogged, totally restricting air flow.

So how much does it cost to operate a fouled heating and cooling system? That is the question asked by the National Air Duct Cleaners Association (NADCA), a not-for-profit trade association representing companies around the world that inspect, clean and restore heating and air conditioning systems. In 2008 NADCA initiated a project with researchers from the University of Colorado at Boulder (CU) to conduct an in-depth study of this issue. The University has extensive research experience and is home to the Larson Building Systems Laboratory, one of the world’s most technologically advanced facilities for researching heating and cooling systems. The purpose of the NADCA research study was to correlate the substantial energy savings that can be attained through complete cleaning of fouled heating and cooling systems.

Research Overview

Dirty Fan: Blowers such as this can become heavily contaminated and require cleaning for maximum efficiency.

Researchers started this project by scouring the Internet and other sources to find literature produced through similar research. Using available literature, researchers developed a computer model designed to quantify the energy savings that could be attained through cleaning heating and cooling systems. From there the researchers conducted a laboratory analysis – they experimented on a house that is contained completely within the Larson Lab – as part of an effort to fine-tune and confirm the computer model. Finally, researchers conducted two field trials to assess the accuracy of the computer model. Through this process, researchers came to realize that there was no comprehensive data available to quantify the savings that can be achieved through cleaning of heavily-fouled systems – the types of systems regularly encountered by NADCA members. (For purposes of this research, “Heavily-fouled” systems are defined as systems where complete cleaning results in a pressure change of at least 30 percent. Pressure change is simply an easier way to measure air flow.) Because of the data limitations, the calculations in the computer model were based on data collected from lightly-fouled systems – systems that are not very dirty.

Key Findings

According to the results of the study, cleaning even lightly-fouled systems can produce substantial energy savings. These findings are based on complete cleaning of heating and air conditioning systems in accordance with NADCA’s ACR 2006 Standard, which includes cleaning ductwork, coils, blower, other air-side system components, and changing the filter. Based on the initial research, cleaning a lightly-fouled system provides, on average, an 11 percent savings off of the energy used for heating and air conditioning.

Next Steps

Cleaning heavily-fouled systems is expected to produce an even greater savings than cleaning systems that are essentially clean. Given the critical importance of air flow, this could be construed as common sense. However, in order to confirm this expectation, NADCA has initiated a broader research effort to quantify the energy savings that can be achieved by complete cleaning of heavily-fouled heating and cooling systems. This research involves collecting data on systems before and after cleaning, and using this data to calculate energy savings.

Summary

It takes a lot of energy to heat and cool a home or building and in fact, the systems used for this purpose account for the majority of energy use.  These systems – even in new buildings – tend to be dirty, and become more heavily fouled through everyday use. Fouled heating and cooling systems can also be problematic for occupants, contributing to poor indoor air quality, system failure and increased energy use. Researchers have proven that cleaning even lightly-fouled heating and cooling systems can result in energy savings of 11 percent. In addition to these savings, consumers who have their heating and cooling system cleaned can benefit from improved indoor air quality, reduced maintenance costs and extended life expectancy for the heating and cooling system. While not yet confirmed, cleaning heavily-fouled systems is expected to produce even greater energy savings.

National Jewish Health® Collaborates with Ductworks for National Asthma and Allergy Month to Help Families Detect Allergens at Home

Allergies & Asthma TestNational Jewish Health and Ductworks, Inc. are collaborating for the second year during National Asthma and Allergy Month, (May) to provide a comprehensive approach for people with allergies and asthma to help them learn if the environment in their homes is contributing to their illness. National Jewish has developed a diagnostic kit to assess the allergen levels in indoor environments.

National Jewish Health and Ductworks are working together on marketing and distribution of the Family Air Care® Indoor Allergens and Mold Test Kit. The kit, developed and serviced by National Jewish Health in Denver, determines levels of common indoor allergens and mold from dust samples taken inside a home, apartment or other building. The kit is now available through Ductworks for $299.

Once the diagnostic assessment of the home is complete, users can go to the Family Air Care® Website to learn how to lower allergen levels in their homes.

“The Family Air Care® kit is the only commercially available indoor-air testing kit that lets customers compare their results with samples from homes around the nation, and offers specific advice about how to interpret the results and what to do after receiving them,” said David Tinkelman, MD, Vice President of Health Initiatives at National Jewish Health.

To use the Family Air Care® Indoor Allergens and Mold Test Kit, consumers simply attach a small capture device to their vacuum-cleaner hose, briefly run the vacuum cleaner in their homes, then mail the collection device to National Jewish Health in a pre-paid envelope provided with the kit. Test results are reported in a secure e-mail. The kits can be ordered online at www.Ductworks.com.

“The Family Air Care® assessment benefits all households, but is especially important to the 70 percent of households where a person with allergies and/or asthma lives,” said Dr. Tinkelman. “The U.S. Department of Health and Human Services recommend that people with allergies and/or asthma reduce levels of allergens and irritants in their homes to improve their health.”

Air Handler Insulation Repair

Most air handler units have fiberglass insulation installed on the interior surfaces to provide thermal insulation, absorb sound, and help to provide the quiet operation of the HVAC system.  As a whole, if properly maintained, air handler insulation has a long-term life expectancy.

In certain instances, the integrity of the fiberglass insulation will degrade and delaminate from the highly varied ranges of temperature, humidity and air turbulence. If the air handler insulation is left unrepaired, raw fiberglass fibers and insulation will enter the air handler components and airstream.

Each time a commercial HVAC system is maintained, the condition of the fiberglass insulation should be evaluated.  If the exposed fiberglass fibers are exposed to the airstream, it is best to remove and replace the air handler insulation, or resurface the damaged insulation with an approved HVAC encapsulate.

Encapsulants, Coatings, & Insulation Repair Products

When fiber glass insulation is initially installed, the exposed face of the fiberglass insulation has a primary seal that locks down the raw fiberglass fibers.  If the primary seal of the air handler unit insulation has begun to delaminate, the most cost effective repair is to encapsulate

Coatings and insulation repair products are designed to repair damaged or degraded HVAC surfaces.  Air handler Insulation repair coatings can range from coatings which lock down the fiberglass fibers to fiberglass coatings that have antimicrobial properties.

Surface treatments for air handler insulation repair must be labeled for the specific use in HVAC&R systems in or on any surfaces that are part of HVAC&R systems, and must be applied to a clean surface.

Air Handler Insulation Replacement

If the air handler insulation requires replacement, it is best to replace the fiberglass insulation with closed cell foam insulation.  Closed cell foam insulation offers many benefits over fiberglass insulation; its finish is smooth and more durable than fiberglass insulation, and resists dirt and moisture accumulation.

Hazards of Mold in Your Ductwork

Mold contamination within air duct systems can pose detrimental health effects to building occupants if left uncorrected.  If mold exists within your air ducts make a plan to investigate the source of the problem, isolate the problem area, and remove the contaminants.

Understanding Mold

Molds are part of the natural environment. Molds are fungi that can be found anywhere – inside or outside – throughout the year. About 1,000 species of mold can be found in the United States, with more than 100,000 known species worldwide.

When excessive moisture or water accumulates indoors, mold growth often will occur, particularly if the moisture problem remains uncorrected. While it is impossible to eliminate all molds and mold spores, controlling moisture can control indoor mold growth.  Molds are usually not a problem unless mold spores land on a damp spot and begin growing. They digest whatever they land on in order to survive. There are molds that grow on wood, paper, carpet, foods and insulation, while other molds feed on the everyday dust and dirt.

Since mold requires water to grow, it is important to investigate the source of the moisture to prevent mold growth.

Hazards of Mold in Your Ductwork

Ventilation systems are designed to distribute a recirculate air within a home.  If mold growth is within the ventilation system, or near an air intake, mold spores can be spread throughout a home.

“Toxic mold syndrome” remains controversial and unproven, but experts agree that it’s best to limit exposure to molds.  The most likely adverse reaction to mold is a respiratory allergic reaction in mold-sensitive people. These reactions are similar to other respiratory allergies, causing sneezing, watery eyes, nasal discharge and congestion.

Cleaning Air Ducts

Consider having the air ducts in your home cleaned if there visible mold growth inside hard surface (e.g., sheet metal) ducts or on other components of your heating and cooling system.

There are several important points to understand concerning mold detection in heating and cooling systems:

  • Many sections of your heating and cooling system may not be accessible for a visible inspection, so ask the service provider to show you any mold they say exists.
  • You should be aware that although a substance may look like mold, a positive determination of whether it is mold or not can be made only by an expert and may require laboratory analysis for final confirmation.
  • If you have insulated air ducts and the insulation gets wet or moldy it cannot be effectively cleaned and should be removed and replaced.
  • If the conditions causing the mold growth in the first place are not corrected, mold growth will recur.

How to Remove Pet Urine Odor from Air Ducts

Pet urine within the air ducts is an extremely unpleasant odor.   Sometimes trouble shooting where the pet urine odor is coming from can be quite difficult.  Here are some great instructions on how to remove pet urine odor from air ducts.

Locating the Sources

Before you can correct a pet urine problem you have to identify all of the areas affected.  Sometimes it can be difficult to isolate or identify source of the pet urine odor.  One of the easiest methods of locating where pets have urinated is through the use of a UV black light.  First darken the room, and then shine the UV black light near vent register openings, pet urine stains will glow in the dark.

Cleaning the Surrounding Areas

As pets urinate into the vent registers, the urine is likely to collect around the carpet or hardwood floor near the air vent register opening.  If you do not clean the areas around the air vent register opening the scent of the urine will cause the pet to instinctively re-soil the area.

One of the best methods for removing the odor is to use baking soda and white vinegar.  Prior to using baking soda and white vinegar, be sure to check with your flooring manufacturer to see if it will affect your floors finish.  Never use ammonia or ammonia based cleaning products.  While ammonia is a good cleaning product, one of the components of pet urine is ammonia, and the odor of the ammonia can lead your pet to instinctively re-soil the area.

DO NOT spray cleaning chemicals into the air ducts, only specific chemicals may be used within air ducts.  Your ventilation system is designed to redistribute air and can potentially distribute the volatile cleaning fumes throughout the home.  If you have accidently poured chemicals within the air ducts, open the doors and windows and call a duct cleaning professional.

Duct Cleaning

After you have cleaned the surrounding area of the air vent registers, hire a professional air duct cleaning contractor.  Debris within the air ducts will harbor pet urine odor.  As the heating and air conditioner is in operation, pet urine odor can distribute throughout the entire home.  An duct cleaning contractor will be able to access the HVAC system and help you to restore the HVAC system to its proper condition.

Indoor Air Quality and Your Homes Heating and Cooling System

What Does the EPA say about Indoor Air Quality?

The US Environmental Protection Agency states that poor indoor air quality is one of the top five environmental threats to our country. So why does the EPA feel so strongly about indoor air in homes and workplaces? Well, according to the EPA, indoor air is on average a staggering three to five times more contaminated than outdoor air and in some instances as high as seventy times.

So why is indoor air so much worse in our home than outdoor air?

The answer is in modern day construction practices. Homes are being built more air tight in an effort to be more energy efficient and environmentally conscious. Older homes are being re-insulated and getting air tight window upgrades. The result is less drafty homes that no longer have natural ventilation to bring in fresh air.

Normal everyday living provides an ongoing source of airborne contaminants like dust, dander, chemicals and other allergens. These pollutants become trapped in your home due to this poor ventilation and then are re-circulated by your heating and cooling system.

So what does this mean for you?

The average American family now spends ninety percent of their time indoors. That means that the bulk of our days is spent breathing in these irritants and pollutants and the health effects are significant. Dust, pollen, household chemicals and smoke can create an unhealthy situation in your home for everyone, but especially for people with compromised respiratory systems such as children, the elderly, and people with asthma and allergy sufferers.

So what can you as a homeowner do to improve your air quality?

Today doctors agree that one of the healthiest things to do is to minimize your exposure to these indoor pollutants, allergens and irritants in your home. One of the most logical places to address indoor pollutants is in your heating and cooling system. Think of this system as the lungs of your home. It takes in air and breathes it out; it circulates all the air and everything in the air throughout your home. In fact, on average all the air in your home passes through your heating and cooling system five to seven times each day.

Begin by making sure that you regularly change furnace filter. While these filters do not eliminate airborne contaminants they can help reduce pollutants from entering your furnace and circulating through the house. Most experts recommend replacing your filter every two months.

Another important step to take to improve the quality of the air in your home, and one that many overlook is having your heating and cooling system thoroughly cleaned. As polluted air is re-circulated through your heating and cooling system dust, dirt, and contaminants are deposited throughout the system overtime. These subtle particles are then picked up by the airstream and are then pushed back out into the living areas of the house to be breathed in by family members. In a large number of homes the heating and cooling system has never been cleaned. Even in newer homes or homes undergoing renovation contaminants such as sawdust and drywall dust left over from construction process are deposited in your ducts.

So how clean is the heating and cooling system in your home? Here is a quick way to check. Remove a vent cover and use a mirror and flashlight to look inside. Or use a small digital camera to take a picture of the inside of your duct. If your ducts are dirty it is time to have your air ducts cleaned.

Choose a NADCA Certified Company

All NADCA members must meet a strict set of requirements:

  • Comply with NADCA’s International cleaning standards
  • Comply with NADCA’s code of ethics.
  • Comply with NADCA’s general liability insurance requirements
  • Maintain at least one certified Air System Cleaning Specialist (ASCS) on staff at all times

The Air Systems Cleaning Specialists Certification verifies that they have successfully completed rigorous testing on heating and cooling system components and cleaning techniques.

Giving your homes heating and cooling system a little attention will keep it and the air in your home cleaner and healthier for you and your family.
