Ducts are the metal or synthetic tubes used to carry air from heating, ventilation, and air conditioning (HVAC) equipment throughout a house. When it comes to the ventilation aspect of air conditioning, the two-word phrase “air ducts” is more appropriate to describe the work that is done in them. Properly installed and well-maintained air ducts are essential for indoor air quality and home comfort. It's important to clean your ducts regularly to prevent the accumulation of dust, dirt, and allergens that can reach your living spaces.
The National Duct Cleaners Association of the United States (NADCA) is a great resource for best practices on how to do this correctly. Additionally, insulating material should be used to cover ducts to prevent air conditioner temperature loss. When installing ducts, it's important to avoid unnecessary folds and opt for smaller tree branch type ducts whenever possible. Return ducts draw air from living spaces and return it to the air conditioning unit, while distribution ducts expel air from the unit throughout the house. Metal ducts usually last longer than flexible ducts due to their stiffer surface. Ken specializes in helping contractors avoid common problems related to HVAC load calculation and duct design errors, duct leak problems, thermal envelope repair, and mold-related problems across the country.
A good air conditioning specialist will calculate air flow, determine the types of ducts needed to meet home requirements, and outline the air distribution system to properly position the equipment and size the ducts.

Many heating, ventilation, and air conditioning contractors don't even offer to refurbish air ducts to correct airflow, so be sure to do your homework. Ducts are an essential part of any HVAC system. To ensure proper installation and maintenance of your home's air ducts for optimal indoor air quality and comfort, consult an expert in HVAC services.
