Changing a furnace filter is simple. First, make sure your furnace is turned OFF so it doesn't blow air when you remove the filter. Next, locate the filter housing on your furnace. This is different for each model, but you can normally find it between the air intake and the furnace.
If you set your filter up backwards, the normally collective end of the device will not face the air supply. In effect, your filter will help keep debris in the air. This results in a clogged filter and improperly cleaned air when it reaches your lungs.
While it may seem obvious, dirty air filters are one of the main causes of poor home air quality. “If your family seems to be getting more colds or having more nasal congestion than usual, it might be a good idea to take a look at your furnace filter,” said Ear, Nose and Throat specialist, Morgan Yost, DO.
If you don't change your AC filter, it will begin to fail. It will no longer be able to filter the air properly, letting dust and contaminants get into the HVAC system. Dust jams the moving parts of an AC such as fan motors and valves. Airflow is restricted which creates a strain on the system.
NO. A furnace filter has a critical job to perform and a filter cannot be run without one. For a furnace to work properly, it should always be equipped with a clean, working filter. As we'll see, a dirty filter can cause problems, and so can having no filter at all.
A Dirty or Discolored Filter
A clean and fresh filter will be mostly white in color but will get darker as it gathers dust and dirt. If your filter looks very dark and dirty, it might be time to change it. If you're unsure about anything, you can get a technician to check your filters for you.
Once you've installed the new water filter, you'll usually need to prepare the filter for use by flushing it out with water. Grab a sturdy container, like a large bucket, and place it under the water dispenser. Hold the dispenser pad down for five seconds, then release for an additional five seconds.
Reusable filters can be washed and replaced. However, the disposable filters you use in your HVAC system aren't made to shed water after they get wet. The moisture the filter retains can encourage mold growth over time, and your HVAC system might spread the mold spores throughout the rest of your home.
If your filter becomes clogged, it can cause your furnace to shut off as a safety feature to prevent damage to the furnace. To fix this problem, simply replace your air filter on a regular basis. If you have pets, be sure to change your air filter more frequently.
After replacing the filter, you should wait at least 12 hours before running the system. If the AC is still not blowing cold air, it could signify that you have a refrigerant leak, a damaged condenser, or your entire mechanical system needs maintenance.
Clogged air filters can run havoc on your HVAC system. If you're still unsure what happens if you don't change your HVAC filter, it can be a health hazard. It can lead to system failure, and the components won't last long or consume more energy.
Cheaper filters, like fiberglass ones, can clog faster than higher-quality options like pleated or HEPA filters. Extreme weather can make your HVAC system work harder, leading to faster filter buildup. Neglecting filter maintenance, like not changing or cleaning regularly, can cause blockages and poor air quality.
Changing your filters every 3 months is the way to maintain proper airflow, efficient operation, and great indoor air quality throughout your home.
The first thing you'll want to do is shut off your HVAC system. You should always avoid changing furnace filters while running the heating system, as various types of debris can enter the furnace — and you certainly don't want that to happen.
Black Soot Deposition
Black soot can quickly turn our air filters black. This is usually a result of burning candles. Candles are made of carbon-based materials that don't all combust when burned. They end up producing tiny soot particles which then get into our carpet, on our furniture, and in our air filters.
On the new filter, find the arrow indicating the proper airflow direction. The arrow must face toward the furnace and away from the return duct that pulls the air in need of heating or cooling.
Without furnace filter, dust, pollen, and mould will settle on your heating and cooling system. When this happens, you will have to clean your home's heating and cooling system more often and replace the air filters far more often than you should. This will also lead to mould, mildew and bacteria build-up.
As the system is working harder to get around clogged air filters, it can cause the entire system to overwork and eventually break. If this happens, you'll need to replace the entire system, which can cost anywhere from $4,000 to $12,000.
If the air filters are clean then you don't have to spend time and money on a new filter! Well, that might not be good. Air filters being dirty shows that they are working correctly, and if they are clean, it can show that they might not be doing their job.
