Air filters that are overdue for a change are a common cause of HVAC system failure. Over time, dirt builds up in the heating and AC filters, causing components such as the motor to go into overdrive, which may eventually overheat your unit.
If your air filter is clogged with dirt and debris, and can no longer trap contaminants, your health and those around you could be at risk. The contaminants can end up back into the indoor air that you breathe. This can cause health issues such as dizziness, headaches, irritable eyes or throat etc.
How Often Do I Need to Change Out My Air Filter? Generally, most air filter manufacturers and HVAC companies recommend changing your air filter every 90 days, or 3 months. That can change based on where your home is located (ex. dusty, dry climates), if you have any pets, and the age of your system and equipment.
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.

What happens if your HVAC filter is dirty? A dirty HVAC filter restricts airflow, which can lead to poor system efficiency, increased energy costs, and wear and tear on the unit.
It's recommended that you replace your car's air filter every 12,000 to 15,000 miles or once a year, whichever comes first. However, if you drive in dusty conditions or on dirt roads frequently, it's best to check more often as this will increase the amount of debris entering into the engine.
A clean air filter is off-white in color and will have no dirt or debris caught in its folds. A dirty air filter, on the other hand, will appear gray or brown in color and you'll likely be able to see dirt trapped between the layers of fabric. This dirt is getting in the way of the flow of oxygen to the engine.
Turn the unit off. Turning this off prevents the air from blowing dust and grit into your system. Open up your vent and remove the used filter.
Is my AC not working because of the filter? Potentially, yes. While there are a whole host of issues that could cause problems with your air conditioning system, a dirty air filter should be the first thing to check if your central air conditioning unit isn't working as properly as it should.
Most engine air filters will cost between $20 to $85, depending on the year, make, and model of your vehicle, and whether you do it yourself or take your vehicle to the dealer or a mechanic.
You may notice a significant decline in HVAC performance, increased energy bills, and decreased comfort in your home. Additionally, delaying filter changes can lead to more extensive damage to your HVAC system, requiring costly repairs or replacement.
Your engine does not work well with contaminated air. The engine does not put out enough power or performance when it is dirty. If your car jerks when you try to accelerate, it may not be getting enough oxygen. The horsepower in your vehicle is dependent entirely on the amount of oxygen the engine receives.
These effects can result in impurities entering the combustion chamber which can damage piston rings, bushes and cylinders. Repairing these damages repeatedly exceeds the cost of a new air filter, so it is certainly not worth taking the risk by cleaning the filter. Cleaning the air filter only improves its appearance.
It can lead to system failure, and the components won't last long or consume more energy. Additionally, your indoor air quality will decrease, taking longer to regulate temperature. You might face serious health issues if you haven't cleaned or changed your HVAC filter in a month or more.
May cause overheating. Also, a dirty air filter will not be able to provide the oxygen needed to provide a proper air-fuel mix. This can cause the temperature of your engine to rise to dangerous levels.
Most manufacturers recommend changing basic fiberglass filters every 30 days. Higher-quality pleated filters should generally be changed every 90 days, though they can potentially last up to six months.
This leads to a variety of issues for your HVAC system including system inefficiency, higher energy bills, inadequate air quality, and ultimately failure. If you haven't been swapping your air filters as frequently as you should, there's no time like the present to start practicing this crucial maintenance step.
When the engine air filter is dirty, the engine may not receive the proper amount of air for efficient combustion. This can lead to decreased fuel efficiency, causing your vehicle to consume more fuel than usual.
Replacing a clogged air filter can increase fuel efficiency and improve acceleration, depending on your car make and model. When you realise that, it makes sense to regularly replace your air filters.
If you let this happen for long enough, the filter could break, releasing all of the pollutants it has accumulated. The pollutants will then float freely though your HVAC system, your house, and eventually your lungs. This can lead to your home's air supply feeling stuffy and dirty, and you could get sick as a result.
While dirty air filters can stop an AC from working, there are many ways to keep your air conditioner well taken care of and working efficiently for a longer time. All you need to do is clean or replace the filter regularly, depending on the type of filter.
A Dirty Filter Can Be Worse Than No Filter
The longer you use your air filter, the dirtier it becomes.
