As previously discussed above, failing to change your filter means debris and dirt will soon clog your unit, causing it to overwork. This in turn raises your energy bills. It takes longer to cool your home. With an old air filter running, you'll notice that it takes so much time for your AC to cool you home.
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.
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.
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.
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.
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.
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.
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.
No, you should never run your AC without a filter!
While your HVAC unit will run, it should never run without an air filter. Dirt is the number one cause of air conditioners breaking down, so running your unit without an installed air filters can cause serious damage.
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.
A new, clean new air filter keeps your HVAC unit running smoother and running longer, extending its useful life.
First, check your filters and coils for dirt and debris that may be impeding airflow. Once you've cleaned the filters and coils, run the air conditioner with just the fan so that the ice accumulation can melt off. If the AC still doesn't blow cold air, it could be that refrigerant levels are too low.
Higher Energy Bills
While fresh air filters can improve airflow and reduce unit stress, dirty or clogged air filters have the opposite effect, causing your system to work harder to adequately cool your residence. This can skyrocket your energy bills, forcing you to pay more money for substandard cooling.
Yes. After a while, the extra strain on your cooling system can cause it to break down. A dirty AC air filter can exacerbate minor mechanical issues or cause rapid wear and tear to machine parts. Eventually, the damage adds up to a broken air conditioner that needs professional AC repair.
Changing your air filter will keep you cool during the summer, warm during the winter, and ensure your system is running as efficiently as possible – reducing overconsumption of energy.
Poor Air Quality
If the filter is too dirty to do its job, those unwanted particles can collect in your ductwork and cling to the internal components of your HVAC system, ultimately diminishing air quality throughout your house.
The short answer: You can get away with running your AC without a filter for a short period of time. However, doing so for longer than 6-8 hours can hurt your system and decrease your home's indoor air quality.
Clogged filters will not properly filter debris from entering the system, damaging internal components. They also cause accelerated wear and tear of parts such as the blower motor, fans, and compressor.
You know, those things tucked away inside your furnace and air conditioner. Most of us forget about them for months or maybe years.. but a little clogged filter can really mess things up in a big way. So, how often should you be replacing them to avoid trouble? The short answer is every 3 months (or every 90 days).
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.
Priority number one: replacing or cleaning it regularly. If you put it off for too long, mold and other contaminants can accumulate in your AC system and circulate throughout your home, potentially triggering allergies and other respiratory issues, says Dr.
While it's possible to run your system with no filter in the air conditioner, HVAC experts don't recommend it at all. Why? It's because having no filter in the air conditioner leaves your system susceptible to all kinds of debris and dirt that would break down your HVAC system or result in expensive repairs.
In a deep sink or outdoors using a garden hose, rinse the filter gently and thoroughly, and allow it to dry. If you need to provide a deep clean, soak the filter in a flat bin with 1 part white vinegar and 1 part warm water for an hour, and then rinse it gently with the hose.
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.
