Air duct cleaning should not be ignored, especially if your air conditioning system has been running for many years. There are several reasons why this is important. First of all, dirt and debris that accumulates inside the air ducts can cause clogs which may lead to problems with heating and cooling. When this happens, your HVAC system could overheat or underperform, causing damage to your home. If you’re unsure whether or not your air ducts need cleaned, here are some telltale signs that they do.
Dusty Filters – If your filters are dusty, then chances are your air ducts are dirty. This means that you should have them cleaned regularly.
Mold Growth – If you notice any mold growth in your air ducts, you should have them cleaned immediately. Mold can produce toxins that can make people sick.
Odors – If you smell unpleasant odors coming from your vents, you should have them inspected right away. You don’t want to wait until things get worse before getting them taken care of.
Duct cleaning involves removing the blower assembly and motor from your furnace, something that only a licensed trained heating and air conditioning technician should do, removing the furnace burners and cleaning. the evaporator coil may also need to be removed for cleaning and this requires an EPA license and should also only be performed by a properly trained and skilled heating and air conditioning Denver technician.
Every vent register needs to be removed. The furnace is cleaned inside and out, the register compartments, boots, vacuumed cleaned and wiped down, and then the ducting can be brushed mechanically or with air brushes while a giant vacuum pulls the air through the system backwards. Then reassembly, burner air fuel adjustment, amperage draw checking on the motor, ductwork inspection for any leaks and it’s done. The little tiny vacuums with the brush tips are nearly worthless on most systems. They simply do not move enough air to create a strong enough vacuum to remove duct contaminates.
