Get matched with top air duct cleaners in Grants, NM

You do need dampers in your HVAC system, but they do help to regulate airflow and give you better control of the temperature in each room of your home. Most HVAC systems will have dampers installed, but this isn't always the case. If you don’t have designated zones in your home, you’ll likely still have valve control dampers on your supply vents for manual control.

While your forced heating system runs, it can pick up dirt, dust, hair, and other particles from inside your house. Changing your furnace filters regularly is key to preventing this debris from getting stuck in your ducts and swirling around your home. With some types of furnaces, there’s also the potential for carbon monoxide leaks. However, staying up-to-date with your HVAC inspections and installing carbon monoxide sensors can help mitigate this risk.

AC evaporator coils should be cleaned at least once per year to keep your unit in good condition. For optimal performance, consider cleaning them twice a year—once before and once after the main cooling season. More frequent cleanings may be necessary for older systems, units with performance issues, or those in climates with high levels of humidity, dust, and dirt.

The Environmental Protection Agency (EPA) states that there's no conclusive evidence to show that dirty or dusty air ducts increase dust and airborne particles in your home or pose any risk to your health. On the other hand, your air ducts require cleaning if there's any mold or mildew, you have a rodent or insect infestation, or you have clogged ducts. Regular air duct cleaning will also extend the life of your HVAC system, leading to less frequent repairs and preventing premature replacement in the future.
