If there do not appear to be any immediate problems then air ducts can be checked every few years. Without checking your air ducts you cannot know when they should be cleaned. It is important to know that even if your system appears to be working fine, it might actually be in need of a clean and could possibly be functioning below its capacity. In such a case, the only evidence you would have for an under optimized HVAC system would be a larger than usual energy bill.
Eventually every home will need to have their HVAC system (all the inner components of your cooling and heating system) cleaned. This is part of regularly scheduled home maintenance and is not usually associated with any urgency.
Home owners of a newly bought residence should have their air ducts cleaned and checked before moving in. Cleaning air ducts before moving in is just like cleaning the bathroom or carpets in that the end goal is to remove any trace of the previous tenants. Imagine if the people who lived in your newly purchased home were smokers or professional painters. Surely after a few days of smoking or painting the associated fumes begin to gather in the HVAC system where they are ventilated and circulated out. If the previous tenants did not clean their air ducts, then the air being circulated in your home is actually their old air. Second hand smoke is bad enough but do you really want second hand air?
Allergy sufferers and residents of post construction (i.e., home remodeling) also risk breathing in indoor air pollution. Construction releases tiny particles of saw and drywall dust that float about in the air. A portion of this dust will be sucked back into the HVAC system to be ventilated with other air. Since these particles are solid they cannot be filtered out so they are just pushed back into the air and into your lungs when you breathe. By the same token dust and dander allergens behave exactly like sawdust particles in that they just participate in the cycle system without actually being filtered out. Allergy sufferers who have their arid cuts cleaned as well as their carpets and upholstery are guaranteed to feel immediate relief and results. All mold problems can start when mold spores enter the house through the ductwork. After entering, mold searches for comfortable conditions to grow. To avoid this, you need to do an air duct mold inspection.
There are several steps to the air duct cleaning process that make sure the HVAC (Heating, Ventilation, and Air Conditioning) system is completely cleaned and the quality of the air inside is improved.
Cleaning your air ducts should be done at least every three to five years, or more often if you have allergies, pets, smokers, or people who smoke in your home, or after home improvements that make dust. This process helps keep the air inside healthy, makes the HVAC system work better, and could lower energy costs.
