When thinking about a heating and air conditioning system, most people just look at the box outside with the big fan on top. However, there are more components than simply this involved in hvac your home. The duct work is a critical component in distributing a good temperature throughout the home, and understanding it's function is important.
The hot and cold air that moves through your house is pulled out of the trained space of one's air ducts. Somewhere in your home (possibly in multiple places) is a grate with a filter, known as the return grill. The function of the return is to pull air out of the trained space and back into the machine. It is then sent down the supply line and into the ports in each room. The suction of the return is so strong (in order to pull right down the line) that small particulates are also picked up. Dust, allergens, pet hair and dander will travel the length of the machine, often getting stuck in several parts of the ductwork. This is the problem that air duct cleaning attempts to unravel. https://energyhomeservice.ca/ductwork/
For homeowners with floor ports may, air duct cleaning is even more necessary to proper AC functioning. Ports are holes in the floor of your house with a small grate covering them. When things are dropped, swept, or pushed across the grate, things can fall into the side, creating an blockage to the supply line. Over time the various garbage builds up, and air cannot flow as effectively through the vent out. With the threat of allergens and other contaminants, homeowners with floor ports should take extra care to clean their ducts regularly. https://energyhomeservice.ca/local/
In addition to obstructions, older systems run a major risk of containing mold. In the summer, a badly protected system will sweat. If the twigs are not properly sealed, the condensation can drip inside and pool. Standing water in an surrounded space creates fungus, which will then be supplied into the house. This is especially a problem if the unit breaks down or does not run for an extended period of time. https://energyhomeservice.ca/local/duct-cleaning-aurora/
There are various ways of removing particulates from the ductwork. One is a simple, quick job, and one is a true is purified. The first method is to you need to a very powerful vacuum, and run it throughout every inch of metal, getting all the loose crud possible. While this will remove large things blocking the path and much of the dust, it does nothing for fungus, or other allergens that won't move with a vacuum. True air duct cleaning requires scrubbing and disinfecting everything to remove all find of contaminants and particulates. Finding a company that will give your ducts this attention is essential to the proper functioning of your HVAC system.
