The contact cleaning method in air duct cleaning involves the use of shop vac style equipment to keep constant contact involving the vacuum hose and duct work surface during the cleaning process. Most of the time the firms that employ this kind for cleaning charges less money for services, because they know that they are limited as to what dirt, dust and debris they can actually pull from the air ducts and they are typically in your house to do the service for 30 minutes to 1 hour. There exists usually no advantage to an air duct cleaning service when this approach to cleaning is performed, however it may be beneficial when the actual vent boots were packed with construction debris or dog food or whatever and also you did not think that cleansing the vent boots and preferred to merely get a cheap provider out to achieve that work 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.

No kidding, every vent inside your home will have a strong vacuum pulling hard from every vent in the home to get a perfect negative air containment, which disallows any cross contamination of dirt discharges in your 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 an effective enough vacuum to perform the service properly. Compressed air tools are used to air wash all the dirt, dust and debris to the power vacuum hose set up in the key duct, trunk line. Once the power vacuum air wash type of air duct cleaning is conducted correctly the service usually takes between 2-4 hours to do 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% of the entire HVAC system.

A normal forced air ventilation is actually a circulatory system of constant air in and air out whenever a furnace is in operation. Companies that are licensed for HVAC will even thoroughly clean the furnace and evaporator coil (indoor coil that is often higher than the furnace).

After he edtwwn once the air duct cleaning service has been performed, you realize that dust is blowing out of all the vents once the furnace cycles, as he disturbed lots of dust throughout the air duct cleaning, because shop vac style machinery have been in good at conducting a thorough air duct cleaning service. You might have referred to as a reputable company that is an ACCA member company utilizing the strongest equipment in the market to give you an “at the start” price quote in the actual same ball park for price because the bait and switch company eventually got away from you, to do the job thoroughly and correctly. If it is too good to be real, this is because it really is. Buyer beware, these bait and switch tactics have already been happening for years and usually the companies that follow these price structures would be the very companies leaving the majority of dirt, dust and debris within your ventilation system that they were paid decent money through the customer to clean up out.
