Many people have embraced air duct cleaning as being a beneficial service, while others have criticized the service and view the service as a complete waste of time and money. Most likely 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 am going to address why I believe that either side raise interesting and excellent points which you as a consumer should consider. In this post I will address different air duct cleaning services 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 most popular scams which are out there so that you as being 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 down the road with a local company.
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 involving the vacuum hose and duct work surface throughout the cleaning process. Generally speaking the firms that employ this kind for cleaning charges less cash for their services, because they already know that these are limited as to what dirt, dust and debris they can actually pull out from the air ducts and are typically at home to execute the service for thirty minutes to one hour. There is usually no advantage to an air duct cleaning service when this method of cleaning is conducted, however it could be beneficial in the event the actual vent boots were packed with construction debris or dog food or whatever and you also failed to think that washing the vent boots and preferred to just get a cheap company out to achieve that be right for you instead. Now, the energy vacuum air wash method in air duct cleaning involves the usage of expensive powerful equipment to enable a technician to deep clean the entire HVAC system. The vacuum hose is usually 8-12″ in diameter and is also placed in the main trunk line to set the whole air duct system within a deep and powerful vacuum.
No kidding, every vent in the home will have a strong vacuum pulling hard away from every vent in the home to get a perfect negative air containment, which disallows any cross contamination of dirt discharges at home to happen through the cleaning process! The vacuum machines may be 220 volt HEPA rated negative air machines, gas powered or diesel powered machines to generate a powerful enough vacuum to execute the service properly. Compressed air tools are employed to air wash each of the dirt, dust and debris towards the power vacuum hose placed in the key duct, trunk line. Once the power vacuum air wash kind of air duct cleaning is carried out correctly the service usually takes between 2-4 hours to do 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% of the entire HVAC system.
It is essential the entire air duct system is cleaned, because if any debris and or contamination remains within the system, then that missed debris or contamination will just recirculate again to recontaminate the environment duct system just as if nothing was even done, after the furnace is switched on again following the air duct cleaning is finished. A typical forced air ventilation is actually a circulatory system of constant air in and air out each time a furnace is at operation. Firms that are licensed for HVAC will even 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, nevertheless the guy is in your house using a shop vac type machine, which means he received $494.00 from you to leave your HVAC system contaminated. After he edtwwn when the air duct cleaning service continues to be performed, you realize dust is blowing out of all the vents if the furnace cycles, while he disturbed a lot of dust during the air duct cleaning, because shop vac style machinery will be in great at performing a thorough air duct cleaning service. You might have known as a reputable company which is an ACCA member company utilizing the most powerful equipment in the market to provide you with an “at the start” price quote in the same ball park for price as the bait and switch company eventually got away from you, to do the job thoroughly and correctly. Should it be too good to be true, this is because it is. Buyer beware, these bait and switch tactics have already been taking place for years and often the companies that follow these price structures would be the very companies leaving the majority of dirt, dust and debris inside your ventilation system that they were paid decent money from the customer to clean out.
