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 am going to address why I do believe that either side raise intriguing and excellent points that you as a consumer should consider. In this post I will address different air duct cleaning san francisco methods and explain what those methods are, I’ll explain credentials to enable you to better understand who the organizations are and who they represent and last I will address the common scams that are out there so that you as a consumer can avoid being caught up into such scams to boost the possibilities of receiving a good service performed correctly, should you ever schedule an air duct cleaning service down the road with a local service provider.
The two most common air duct cleaning methods would be 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 using shop vac style equipment to maintain constant contact between the vacuum hose and duct work surface throughout the cleaning process. Most of the time the firms that employ this kind for cleaning charges less cash for his or her services, because they already know that they are limited as to what dirt, dust and debris that they may actually pull from the air ducts and therefore are typically in your house to perform the service for 30 minutes to an hour. There is certainly usually no benefit to an aura duct cleaning service once this method of cleaning is performed, however it may be beneficial when the actual vent boots were full of construction debris or dog food or whatever and also you did not think that washing the vent boots and preferred to simply obtain a cheap company out to do that meet your needs instead. Now, the energy vacuum air wash method in air duct cleaning involves using expensive powerful equipment to enable a technician to deep clean the whole HVAC system. The vacuum hose is usually 8-12″ in diameter and it is set up in the key trunk line to put the complete air duct system within deep and powerful vacuum.
No kidding, every vent in the house may have an effective vacuum pulling hard from every vent in the house for a perfect negative air containment, which disallows any cross contamination of dirt discharges in your house to occur during the cleaning process! The vacuum machines could be 220 volt HEPA rated negative air machines, gas powered or diesel powered machines to create a powerful enough vacuum to execute the service properly. Compressed air tools are utilized to air wash all the dirt, dust and debris for the power vacuum hose placed in the primary duct, trunk line. When the power vacuum air wash form of air duct cleaning is carried out correctly the service usually takes anywhere from 2-4 hours to perform 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% in the entire HVAC system.
It is essential that this entire air duct system is cleaned, as if any debris or contamination is left in the system, then that missed debris as well as contamination will just recirculate again to recontaminate air duct system as if nothing was even done, when the furnace is switched on again following the air duct cleaning is done. An average forced air ventilation is actually a circulatory system of constant air in and air out each time a furnace is at operation. Companies that are licensed for HVAC may also thoroughly clean the furnace and evaporator coil (indoor coil which is often above the furnace).
If the job was performed correctly that could be fine, nevertheless the guy is within your house having a shop vac type machine, which suggests he received $494.00 by you to depart your HVAC system contaminated. After he edtwwn when the air duct cleaning service has been performed, you realize dust is blowing out of all the vents if the furnace cycles, while he disturbed a lot of dust through the air duct cleaning, because shop vac style machinery are in great at performing a thorough air duct cleaning service. You can have called a reputable company that is certainly an ACCA member company utilizing the strongest equipment in the market to offer you an “in advance” price quote right in the same ball park for price as the bait and switch company eventually got out of you, to do the job thoroughly and correctly. If it is too good to be true, that is because it is actually. Buyer beware, these bait and switch tactics happen to be taking place for a long time and often the firms that follow these price structures are the very companies leaving the vast majority of dirt, dust and debris within your ventilation system that they were paid good money by the customer to clean out.
