Air duct cleaning is actually a fairly new industry which has exploded as a $4 Billion a year industry in the usa alone, nowadays. Some individuals have embraced air duct cleaning as being a beneficial service, and some have criticized the service and view the service as a waste of time and expense. Probably 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 intriquing, notable and very good points that you as a consumer should consider. In this article I am going to 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 number of choices of receiving a good service performed correctly, should you ever schedule an air duct cleaning service later on with a local service provider.
The two most common air duct cleaning methods would be the “contact cleaning” method and the “Power vacuum air wash” method in air duct cleaning. The contact cleaning method in air duct cleaning involves using shop vac style equipment to keep constant contact between the vacuum hose and duct work surface during the cleaning process. Generally speaking the firms that employ this form of cleaning charges less money for their services, because they know that these are limited in what dirt, dust and debris that they can actually pull out from the air ducts and therefore are typically at home to perform the service for thirty minutes to 1 hour. There is usually no advantage to an aura duct cleaning service if this method of cleaning is conducted, however it might be beneficial when the actual vent boots were full of construction debris or dog food or whatever and you failed to feel like washing the vent boots and preferred to merely get a cheap provider out to do that work for you instead. Now, the power vacuum air wash method in air duct cleaning involves the usage of expensive powerful equipment to permit a technician to deep clean the entire HVAC system. The vacuum hose is generally 8-12″ in diameter and it is set up in the main trunk line to put the whole air duct system under a deep and powerful vacuum.
No kidding, every vent inside your 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 at home to take place during the cleaning process! The vacuum machines might be 220 volt HEPA rated negative air machines, gas powered or diesel powered machines to generate a powerful enough vacuum to perform the service properly. Compressed air tools are used to air wash each of the dirt, dust and debris for the power vacuum hose installed in the main duct, trunk line. When the power vacuum air wash type of air duct cleaning is performed correctly the service normally takes from 2-4 hours to execute the service in 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 the entire air duct method is cleaned, because if any debris as well as contamination is left inside the system, then that missed debris and or contamination will just recirculate again to recontaminate air duct system just as if nothing was even done, after the furnace is excited again right after the air duct cleaning is done. 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 certainly often above the furnace).
In the event the job was performed correctly that would be fine, though the guy is in your house using a shop vac type machine, meaning he received $494.00 by you to depart your HVAC system contaminated. After he edtwwn after the air duct cleaning service continues to be performed, you realize that dust is blowing out of all the vents if the furnace cycles, while he disturbed a lot of dust throughout the air duct cleaning, because shop vac style machinery are in effective in conducting a thorough air duct cleaning service. You can have referred to as a reputable company which is an ACCA member company utilizing the strongest equipment in the business to provide you with an “in advance” price quote right in the same ball park for price because the bait and switch company eventually got out of you, to do the job thoroughly and correctly. Should it be too good to be true, this is because it really is. Buyer beware, these bait and switch tactics have already been taking place for years and usually the firms that follow these price structures are the very companies leaving the vast majority of dirt, dust and debris inside your ventilation system they were paid good money through the customer to clean up out.
