"Both of them Colton and Cody, were professional and courteous and told me what they were doing and why. They showed me how the filter looked before and after and I could not believe what came out of my ducts. My house smells better and I am sure my furnace will be more efficient, and I will spend less time dusting. They are polite and know what they are doing. If you have not had your ducts cleaned, or it has been along time, I would recommend calling them. The will give you an estimate and get you scheduled and show up when they say they say they will. I didn't realize they also do chimney work and several other things until chatting with them and although I don't have a fireplace, I recommended them to my neighbor who has never had their chimney cleaned. There are companies out there that tell you they are cleaning your ducts when they are just blowing around air but this is not one of them.
Thank you Colton and Cody for making the air in my house clean again.

Air Duct Cleaning questions, answered by experts

You can experience respiratory problems if your return air vents are dirty. While this doesn’t necessarily mean dirty return air vents will make you sick, they can exacerbate symptoms of respiratory illness, such as sneezing, wheezing, and coughing. This is due to the extra contaminants in the air, which may include allergens and dander that can affect people with allergy sensitivities.

Areas of your home may provide an ideal environment for green or black mold. Most molds love moisture and will thrive in wet or damp areas. Some types of mold, such as Stachybotrys chartarum, grow well on materials commonly used in homes, such as gypsum board and wood. Mold may also grow in areas where there are leaks, such as in bathrooms, kitchens, or basements.

Return air ducts should generally not be installed in rooms with high humidity, contaminants, or strong odors. This includes bathrooms, kitchens, garages, closets, attics, and furnace or boiler rooms. Placing vents in these areas can draw moisture, fumes, odors, and potentially hazardous gases like carbon monoxide into your HVAC system, which can damage ductwork, promote mold growth, and compromise your home's indoor air quality and safety. According to the International Code Council, there are some exceptions. For example, a return duct may be placed in a kitchen if it is at least 10 feet away from cooking appliances and serves only that room. Similarly, a garage can have a return duct if it is part of a dedicated forced-air system that only serves the garage. For optimal performance, prioritize installing return air vents in central locations and rooms with consistent temperature needs, such as bedrooms and living spaces. If you are unsure, consult a professional duct installer for guidance.

You should plan to change your AC unit's filter every one to three months, depending on the manufacturer's recommendations. You should also clean the coils at least once per year, but if you have pets or someone in your household has allergies, you might need to clean them more often. Fortunately, many pros will clean the coils and change the filter for you during an inspection, which you should schedule once or twice per year.

The best type of basement ventilation system depends on your budget, the moisture in your basement’s air, and the types of windows you have down there. You should consider all of these factors when choosing a ventilation system. However, the most effective method for basement ventilation is an energy recovery ventilator (ERV) or a whole-house ventilation system, which preheats or precools incoming air from the outside while also managing water vapor.
