Air duct cleaning is a relatively new industry that has skyrocketed as a $4 Billion a year industry in america alone, today. Some people have embraced air duct cleaning as being a beneficial service, while some have criticized the service and view the service as a complete 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 the following paragraphs I am going to address why I do believe that both sides raise intriquing, notable and very good points that you as a consumer should look into. In this post I am going to address different duct cleaning san francisco methods and explain what those methods are, I’ll 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 being a consumer can avoid being caught up into such scams to boost the number of choices of getting a good service performed correctly, should you ever schedule an air duct cleaning service down the road with a local company.
Two of the most common air duct cleaning methods are the “contact cleaning” method and 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. Generally speaking the businesses that employ this kind for cleaning charges less money for his or her services, because they already know that these are limited with what dirt, dust and debris that they can actually pull from the air ducts and are typically at home to perform the service for 30 minutes to an hour. There exists usually no benefit to an air duct cleaning service when this approach to cleaning is performed, however it may be beneficial when the actual vent boots were full of construction debris or dog food or whatever and you also failed to feel as if cleaning the vent boots and preferred to merely get a cheap service provider out to do that be right for you instead. Now, the energy vacuum air wash method in air duct cleaning involves the use of expensive powerful equipment to permit a technician to deep clean the complete HVAC system. The vacuum hose is usually 8-12″ in diameter and it is placed in the primary trunk line to put the complete air duct system within deep and powerful vacuum.
No kidding, every vent in the house will have a powerful vacuum pulling hard off of every vent in the home for any perfect negative air containment, which disallows any cross contamination of dirt discharges at home to happen throughout 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 execute the service properly. Compressed air tools are used to air wash each of the dirt, dust and debris to the power vacuum hose installed in the main duct, trunk line. When the power vacuum air wash form of air duct cleaning is performed correctly the service typically takes between 2-4 hours to do 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, as if any debris or contamination remains inside the system, then that missed debris and or contamination will just recirculate again to recontaminate air duct system as though nothing was even done, when the furnace is excited again after the air duct cleaning is complete. A typical forced air ventilation is actually a circulatory system of constant air in and air out when a furnace is within operation. Firms that are licensed for HVAC will also thoroughly clean the furnace and evaporator coil (indoor coil which is often above the furnace).
If the job was performed correctly that might be fine, however the guy is in your house with a shop vac type machine, meaning he received $494.00 from you to go out of your HVAC system contaminated. After he edtwwn after the air duct cleaning service has become performed, it becomes clear that dust is blowing out of all of the vents once the furnace cycles, as he disturbed plenty of dust during the air duct cleaning, because shop vac style machinery will be in good at conducting a thorough air duct cleaning service. You could 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 “up front” 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. When it is 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 often the businesses that follow these price structures are the very companies leaving the majority of dirt, dust and debris inside your ventilation system that they were paid decent money by the customer to clean out.
