"Technician that did the work was knowledgeable and friendly. The price was the best I had found in our area. The technician heard some jewelry being sucked out of the vent and he left the material in a bucket for me to sift through and I found a lost earring. It took 3 hours to do 12 house vents and the dryer vent. Great Job!!"

Air Duct Cleaning FAQs, answered by experts

A blocked return air vent can cause your HVAC system to work much harder and, therefore, less efficiently. The result is higher utility bills and poorer air quality. A blocked return air vent can also cause unpleasant dust, dander, and odors to linger in your home’s air.

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.

If you don't regularly change your HVAC air filter, it will become clogged with dust, dirt, and other contaminants. This blockage forces the system to work harder to circulate air, leading to several negative consequences. You may experience higher energy bills, poor temperature regulation, reduced air quality, and slower system performance. Over time, this added strain can cause parts to break more frequently, lead to system failure, and ultimately shorten the lifespan of your entire HVAC unit. In some cases, it can also contribute to health problems. It's recommended to change the filter at least every three months.

No, it’s not normal for AC vents to drip condensation. A sweating AC vent is a sign of something wrong and can lead to issues like air duct rust or mold growth. Your HVAC unit might not be working efficiently because of a dirty filter or clogged ducts. Alternatively, your ductwork might not have adequate insulation, which allows the cool air in the ducts to meet the humid air outside, causing condensation. 

To get water out of AC vents, first identify the source of the water. Check other air vents in your home for signs of moisture. If you can’t find any, look around the room for anything that might have seeped water in like an overwatered plant or a spill. Meanwhile, if you notice more than one air vent wet in other areas of your home, it’s more than likely an issue with your insulation, roof, or air conditioner. Start by hiring an HVAC technician who can trace the source of the leak for you.
