Indoor air quality is a hot-button issue for families and business owners. Air conditioning, heating, and HVAC systems are designed to pull air into the units and force it out through your ductwork. The problem is that many homes and office buildings are tightly sealed to conserve energy and contain the warm and cool air. This is excellent for energy savings but poses a concern when you breathe recirculated air every day. Brennan’s Heating & Air Conditioning delivers top-of-the-line air purifiers, ventilators, humidifiers, and ductwork services to ensure your home and business have excellent air quality. Indoor air pollution is typically invisible. In some cases, you will be able to detect impurities because of distinct odors. Between work and home, you spend a lot of time indoors breathing air that may be contaminated with pet dander, pollen and pet fur, cleaning chemicals, dust, mold, fungi, bacteria, and viruses. These are considered allergens and can cause respiratory, throat, and eye irritation and other symptoms that mimic a cold or the flu virus.

If there are children or elderly persons in your home, it is important to take all measures to rid your home of these and other allergens, as they are more susceptible to their effects. Brennan’s Heating & Air Conditioning delivers clean, fresh air with the latest air purifiers. Our systems pull air through the patented air purifying system and then bursts the impurities with an electrical charge killing the pathogens. Improving ventilation is not as simple as just opening a window for fresh air because outdoor air is polluted as well. A ventilation system that is equipped with filters can deliver fresh air without the contaminants. Today’s ventilators are quiet and boast “no tools” maintenance. Some airborne contaminants are water-soluble. Reducing humidity helps to eliminate particles that travel within the damp, indoor air. Although air conditioners reduce humidity, a dehumidifier provides that extra edge, especially for those family members and coworkers who suffer from asthma.

Along with preventing mold and mildew growth, a humidifier works to eradicate dust mites that thrive in humidity. If you have a furnace, a humidifier is excellent to keep your indoor air from becoming overly dry. A Brennan’s Heating & Air Conditioning expert will measure the humidity in your home to determine if your home is excessively dry or damp and recommend options that suit your needs. UV Lamps are a great way to kill mold inside your HVAC coils and keep it from growing back. Mold spores will stick to and build up in the HVAC coils. From there, they have the potential to become airborne, entering your home or business through the ductwork. UV Lamps can be installed directly within your heating and cooling system where they work to ensure your coils stay mold and bacteria free and your indoor air quality remains at a healthy level. Air ducts are notorious for harboring pollutants. In addition to the buildup of dust, debris, mold, fungi, and other contaminants, ductwork can be an ideal hiding place for insects and rodents.

If your air ducts are cracked or leaky, squirrels, rats, and other outdoor critters can find their way into your home or office building. To keep your ductwork free of debris, particles, and pests, it is important to have it inspected regularly and schedule professional air duct cleaning every few years. Your Brennan’s Heating & Air Conditioning contractor will be able to discuss a regular maintenance program to ensure your ductwork stays in great condition. As HVAC technology continues to advance, the more options we have to control our indoor air quality. Call Brennan’s Heating & Air Conditioning for an in-home evaluation of your air quality. We are committed to delivering cleaner, healthier air to your home and business. SERVPRO of College Park / Hyattsville Professionals routinely inspect the heating, ventilation and air conditioning unit (HVAC).  For more information on HVAC and air duct cleaning, call us today, (301) 779-3662.Americlean Services Corporation is a certified member of NADCA (National Air Duct Cleaners Association), which sets the standards of the industry.

We follow their guidelines to ensure that you receive the highest quality of service possible. We’ve helped combat indoor air pollution for satisfied customers throughout Northern Virginia and the greater Washington DC Metropolitan area since 1984. As your system circulates air throughout a dwelling, the air ducts get dirty by gradually accumulating dust and allergens, most of which are produced by occupants. Pet hair and dander increase this accumulation drastically. This indoor air is recycled through the homes, increasing the accumulation of debris inside the air ducts constantly. After the cleaning is finished, we re-inspect the air duct system with our fiber optic cameras in order to verify its cleanliness. We encourage you to see for yourself the cleanliness of your air ducts during and after the cleaning process. Is duct cleaning a dusty process? Not if it is properly performed. Americlean’s vacuums use HEPA filtration to ensure that 99.97% of particulate matter is contained within the vacuum.

Is cutting a hole in the duct work necessary?It is the only way to capture the debris before it reaches the air handling unit and its delicate components. They also make your ducts easier to clean again in the future. Without an access opening, the majority of debris would be left behind in the main duct. Is using a brush inside the duct work needed?Americlean’s electric rotary brushes are long and flexible enough to clean any duct configuration. Some companies use chimney sweep brushes, which simply cannot do the job. Many companies rely on suction alone and do not use brushes in their process. Vacuuming by itself does not remove any debris without direct contact. No matter how powerful the machine is, only internal agitation will remove contaminants. NADCA standards state that agitation devices (brushes) are necessary to effectively clean duct surfaces (ACR: The NADCA Standard for Assessment, Cleaning, Restoration of HVAC Systems, Section 4.3). Is sanitizing my duct work a good idea?

No, it is not. The EPA has not registered any chemicals as a sanitizing agent inside ductwork. A fungistatic or bacteriostatic agent may be used, but such applications are not recommended as a general practice, unless microbial growth is visually evident. If microbial growth is suspected in a duct system, we recommend testing by an indoor environmental professional (IEP). Fungistatic and bacteriostatic agents applied to the interior of a duct system must be registered with the EPA, because most of these chemicals are classified as pesticides (toxic chemicals). Dust in a duct system consists predominantly of organic based matter. This is a nutrient source for biological growth and sustenance. Since the food source is removed by professional cleaning methods, the application of a sanitizer as a precautionary measure is redundant. Why do some companies only charge $99? These companies send a salesman to your home instead of a technician. They classify the aspects of a thorough cleaning as “extras” that carry heavy additional charges.
