The two most common air duct cleaning methods would be the “contact cleaning” method as well as the “Power vacuum air wash” method in air duct cleaning. The contact cleaning method in air duct cleaning involves the use of shop vac style equipment to keep constant contact between the vacuum hose and duct work surface through the cleaning process. Generally speaking the companies that employ this type of cleaning charges less money for their services, because they already know that they may be limited in what dirt, dust and debris that they can actually pull from the air ducts and therefore are typically in your house to perform the service for half an hour to one hour. There is usually no help to an aura duct cleaning service once this method of cleaning is conducted, however it might be beneficial if the actual vent boots were full of construction debris or dog food or whatever and also you failed to feel as if cleaning the vent boots and preferred to just get a cheap service provider out to do that meet your needs instead. Now, the power vacuum air wash method in air duct cleaning involves the usage of expensive powerful equipment to enable a technician to deep clean the complete HVAC system. The vacuum hose is normally 8-12″ in diameter and is placed in the primary trunk line to place the entire air duct system within a deep and powerful vacuum.
No kidding, every vent inside your home could have a strong vacuum pulling hard away from every vent inside your home for a perfect negative air containment, which disallows any cross contamination of dirt discharges at home to happen throughout the cleaning process! The vacuum machines could be 220 volt HEPA rated negative air machines, gas powered or diesel powered machines to produce an effective enough vacuum to do the service properly. Compressed air tools are used to air wash all the dirt, dust and debris to the power vacuum hose set up in the key duct, trunk line. Once the power vacuum air wash form of air duct cleaning is conducted correctly the service normally takes from 2-4 hours to do the service inside an average sized home. Reputable companies will clean all supply boots, adjoining supply branch lines, supply trunk line(s), supply plenum, return boots, return channels, return trunk line(s) and return plenum, virtually 100% of the entire HVAC system.
It is essential the entire air duct method is cleaned, since if any debris or contamination remains inside the system, then that missed debris as well as contamination will just recirculate again to recontaminate the air duct system as though nothing was even done, after the furnace is turned on again after the air duct cleaning is finished. A typical forced air ventilation is a circulatory system of constant air in and air out when a furnace is in operation. Companies that are licensed for HVAC will even thoroughly clean the furnace and evaporator coil (indoor coil that is often higher than the furnace).
When the job was performed correctly that could be fine, though the guy is within your house having a shop vac type machine, which suggests he received $494.00 from you to go out of your HVAC system contaminated. After he edtwwn once the air duct cleaning service has become performed, you realize dust is blowing out of all the vents if the furnace cycles, as he disturbed a lot of dust throughout the air duct cleaning, because shop vac style machinery are in good at performing a thorough air duct cleaning service. You could have known as a reputable company that is an ACCA member company utilizing the strongest equipment in the business to give you an “at the start” price quote right in the same ball park for price because the bait and switch company eventually got from you, to complete the job thoroughly and correctly. When it is too good to be true, this is because it really is. Buyer beware, these bait and switch tactics have already been happening for years and in most cases the firms that follow these price structures would be the very companies leaving nearly all dirt, dust and debris within your ventilation system they were paid good money by the customer to wash out.
