Air duct cleaning is a fairly new industry which has skyrocketed as a $4 Billion a year industry in the United States alone, today. 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 money. Most likely though, people 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 do believe that each side raise intriguing and great points which you as a consumer should look into. In this post I will address different duct cleaning 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 will address the common scams which are out there so that you as a consumer can avoid being caught up into such scams to boost the options of receiving a good service performed correctly, should you ever schedule an air duct cleaning service later on with a local service provider.
Two of the most common air duct cleaning methods are definitely the “contact cleaning” method and also the “Power vacuum air wash” method in air duct cleaning. The contact cleaning method in air duct cleaning involves the usage of shop vac style equipment to maintain constant contact between the vacuum hose and duct work surface throughout the cleaning process. Generally speaking the firms that employ this kind for cleaning charges less money for services, because they know that they may be limited with what dirt, dust and debris that they can actually pull from the air ducts and they are typically in your home to do the service for 30 minutes to an hour. There is usually no help to an aura duct cleaning service if this way of cleaning is conducted, however it may be beneficial in the event the actual vent boots were packed with construction debris or dog food or whatever and also you failed to feel as if cleansing the vent boots and preferred to merely get yourself a cheap service provider out to achieve that meet your needs instead. Now, the energy vacuum air wash method in air duct cleaning involves using expensive powerful equipment to permit a technician to deep clean the complete HVAC system. The vacuum hose is generally 8-12″ in diameter and it is installed in the key trunk line to place the entire air duct system within a deep and powerful vacuum.
No kidding, every vent in the home may have an effective vacuum pulling hard from every vent in the house for any perfect negative air containment, which disallows any cross contamination of dirt discharges in your home to take place throughout the cleaning process! The vacuum machines may be 220 volt HEPA rated negative air machines, gas powered or diesel powered machines to produce an effective enough vacuum to execute the service properly. Compressed air tools are used to air wash all the dirt, dust and debris towards the power vacuum hose installed in the primary duct, trunk line. Once the power vacuum air wash kind of air duct cleaning is carried out correctly the service usually takes anywhere from 2-4 hours to execute 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% in the entire HVAC system.
It is essential that this entire air duct method is cleaned, as if any debris as well as contamination remains in the system, then that missed debris and or contamination will just recirculate again to recontaminate the air duct system as if nothing was even done, when the furnace is switched on again after the air duct cleaning is complete. A typical forced air ventilation is 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 over the furnace).
In the event the job was performed correctly that might be fine, however the guy is within your house with a shop vac type machine, meaning he received $494.00 on your part to depart your HVAC system contaminated. After he edtwwn when the air duct cleaning service has been performed, it becomes clear that dust is blowing out of all the vents if the furnace cycles, while he disturbed lots of dust during the air duct cleaning, because shop vac style machinery have been in great at performing a thorough air duct cleaning service. You might have called a reputable company which is an ACCA member company utilizing the strongest equipment in the market to offer you an “up front” price quote in the same ball park for price as the bait and switch company eventually got from you, to do the job thoroughly and correctly. When it is too good to be true, this is because it is actually. Buyer beware, these bait and switch tactics happen to be taking place for years and in most cases the businesses that follow these price structures would be the very companies leaving nearly all dirt, dust and debris in your ventilation system that they were paid decent money through the customer to wash out.
