Air duct cleaning is actually a fairly new industry that has skyrocketed as a $4 Billion a year industry in america alone, in the 21st century. Some individuals have embraced air duct cleaning as a beneficial service, while some have criticized the service and view the service as a total waste of time and expense. Probably though, individuals who have their varying view points for and against the service are both correct on this issue in one way or another| and in this post I will address why I think that both sides raise interesting and excellent points that you as a consumer should consider. In this article I am going to address different air duct cleaning services san francisco methods and explain what those methods are, I will explain credentials so that you can better understand who the organizations are and who they represent and last I am going to address the common scams that are out there so that you as a consumer can avoid being caught up into such scams to increase the possibilities of getting a good service performed correctly, should you ever schedule an air duct cleaning service in the future with a local service provider.
Two of the most common air duct cleaning methods are definitely 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 maintain constant contact in between the vacuum hose and duct work surface through the cleaning process. In most cases the firms that employ this type of cleaning charges less money for his or her services, because they know that they are limited in what dirt, dust and debris they can actually pull from the air ducts and are typically in your home to do the service for half an hour to 1 hour. There is certainly usually no help to an air duct cleaning service when this approach to cleaning is performed, however it may be beneficial if the actual vent boots were packed with construction debris or dog food or whatever and also you failed to think that cleansing the vent boots and preferred to simply obtain a cheap provider out to achieve that be right for you instead. Now, the ability vacuum air wash method in air duct cleaning involves the usage of expensive powerful equipment to permit a technician to deep clean the complete HVAC system. The vacuum hose is normally 8-12″ in diameter and is also installed in the main trunk line to set the whole air duct system under a deep and powerful vacuum.
No kidding, every vent in the home may have a strong vacuum pulling hard off of every vent inside your home to get a perfect negative air containment, which disallows any cross contamination of dirt discharges in your home to occur during the cleaning process! The vacuum machines might be 220 volt HEPA rated negative air machines, gas powered or diesel powered machines to produce a strong enough vacuum to perform the service properly. Compressed air tools are employed to air wash all the dirt, dust and debris towards the power vacuum hose set up in the main duct, trunk line. When the power vacuum air wash form of air duct cleaning is carried out correctly the service normally takes from 2-4 hours to execute the service within 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% from the entire HVAC system.
It is important that this entire air duct method is cleaned, because if any debris or contamination remains inside the system, then that missed debris or contamination will just recirculate again to recontaminate the air duct system as though nothing was even done, after the furnace is switched on again right after the air duct cleaning is done. A normal forced air ventilation is really a circulatory system of constant air in and air out each time a furnace is at operation. Businesses that are licensed for HVAC will also thoroughly clean the furnace and evaporator coil (indoor coil which is often higher than the furnace).
When the job was performed correctly that might be fine, however the guy is in your own home having a shop vac type machine, which suggests he received $494.00 from you to depart your HVAC system contaminated. After he edtwwn once the air duct cleaning service has become performed, it becomes clear that dust is blowing out of all the vents when the furnace cycles, as he disturbed lots of dust through the air duct cleaning, because shop vac style machinery are in great at conducting a thorough air duct cleaning service. You can have called a reputable company that is an ACCA member company utilizing the strongest equipment in the business to offer you an “up front” price quote in the actual same ball park for price as the bait and switch company eventually got from you, to complete the job thoroughly and correctly. Should it be too good to be real, that is because it is actually. Buyer beware, these bait and switch tactics happen to be taking place for a long time and usually the firms that follow these price structures are definitely the very companies leaving the majority of dirt, dust and debris within your ventilation system they were paid good money through the customer to clean out.
