Most drivers do not think about the cabin air filter until they notice bad odors, less air flow or dust and dirt in their cars. These indicators are the most obvious signs of a dirty cabin air filter. However, a dirty cabin filter can lead to other, more serious issues that aren't just limited to dust and odors.
No, you should never run your AC without a filter!
Although there are specific situations when this may be acceptable for a very short time, in most situations running your AC without a filter could be disastrous. Generally, anytime you run your air conditioning system without an air filter you are taking a major risk.
When you leave an AC unit's air filter clogged for too long, you can experience a failure of the entire system. This is because the unit can only work for so long at twice the power before it finally breaks down.
Problems Associated With a Dirty Filter
Consider replacing it every year in February before the spring allergy season begins. Another problem that comes with a clogged filter is poor HVAC efficiency. As a result, your car's heating and cooling system has to work harder, potentially causing the blower motor to burn out.
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.
These noises might be wheezing or coughing. These noises are generated by a clogged engine air intake that is preventing the vehicle's engine from getting adequate air. Causing a reduction in power.
With a few tools, some simple instructions, and an extra 15 minutes, you can replace your air filter all by yourself and get back on the road.
A new, clean new air filter keeps your HVAC unit running smoother and running longer, extending its useful life.
You might wonder about the risks of running your AC without a filter, even temporarily. The simple answer is: not for long. Ideally, your AC should never operate without a filter for more than 6-8 hours. Going beyond this can negatively affect both your system's health and your home's air quality.
In addition to affecting air quality, a dirty cabin air filter can also affect the performance of the vehicle's heating and air conditioning system. The system must work harder to circulate air when the filter is clogged, which can lead to reduced efficiency and increased strain on the system.
Many disposable air conditioner filters should be replaced rather than cleaned, as cleaning with water can lead to possible mold issues. Clean the coils and fan of the AC regularly, using a canister of condensed air to blow away dust and buildup.
A fresh cabin air filter can significantly enhance airflow. Increased airflow leads to a more comfortable and cooler feeling in your vehicle. Don't neglect this simple but vital aspect of your vehicle's maintenance.
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.
Reduced Efficiency
This can result in a noisy or ineffective air conditioning system. This can be a huge pain during those hot summer months - if your cabin air filter is full of debris and dirt, it'll take way longer for your cabin to cool down.
Your vehicle has two common air filters: the cabin air filter and the engine air filter. Both need to be changed regularly to keep your car running in tip-top shape.
