Air filters in your home air conditioning system will stop any dirt or dust from getting into the evaporator coils. These coils are what actually cools the air in your home. If these coils get dirty, it will reduce the efficiency of your AC unit and make it work harder to cool your home.
A clean filter will also help to prevent any mold or bacteria from growing inside your AC unit, which can cause serious health problems for you and your family.
Can a dirty air filter cause AC to not cool?
If your air filter is dirty, it can cause your AC unit to not cool as efficiently as it should. This means that your home will not be as cool as it could be, and you may even notice that your energy bills are higher than usual.
The buildup of dust and dirt on your air conditioning system can cause poor cold airflow which then leads to ice accumulation. This causes the AC unit’s coils to get covered with frost, making it less effective at cooling your home.
This trapped and frozen moisture on its coils causes ice to form which then leads to your AC unit shutting down completely. So, if you notice that your AC unit isn’t cooling as well as it used to, make sure to check the air filter and clean or replace it if necessary.
What happens if you don’t clean AC filter?
If you don’t clean your AC filter, it will eventually get so clogged that air can’t flow through it properly. This can cause a number of problems, such as:
- Your AC unit won’t be able to cool your home as efficiently.
- Your AC unit may freeze up.
- Your AC unit may shut down completely.
In extreme cases, a clogged air filter can cause your AC unit to catch fire. So it’s important to keep your air conditioner’s filter clean and replace it when necessary.
Can I run my AC without a filter for one night?
Running your AC without a filter is okay for short periods of time, but it can cause serious damage over longer durations. It’s important to know that your AC unit needs a filter to protect it from dirt and dust.
Without a filter, these particles can build up and clog the evaporator coils. This leads to decreased efficiency and higher energy bills. In extreme cases, it can even cause your AC unit to catch fire.
So while you may be able to get away with running your AC without a filter for one night, it’s not something we would recommend doing on a regular basis.
Will changing the filter help AC?
Yes, changing your air conditioner’s filter will help it to run more efficiently. A clean filter will allow air to flow more freely through the unit, which helps to prevent the coils from freezing up. It also helps to prevent mold and bacteria from growing inside the unit, which can cause serious health problems.
Changing your AC filter not only helps to improve the quality of air in your home, but it can also save you money. The US Department of Energy found in 2015 studies done by 5 different universities around America how replacing an old clogged or full one could lower AC consumption by 15%.
So, if you notice that your AC unit isn’t cooling as well as it used to, make sure to check the air filter and clean or replace it if necessary.
How often should you change your air conditioner filter in your house?
So this begs the question, how often should you replace your air filters? Well, the answer depends on the type and size of the filter.
Most people with normal indoor conditions recommend replacing them every 90 days. Many professionals also recommend 45-60 day intervals for those with pets, smokers, or large amounts of dust in their homes.
You can also buy air filters that are supposed to last up to 6 months. However, we recommend replacing them more frequently if you have any of the conditions mentioned above.
If you’re not sure how often to replace your filter, it’s always best to err on the side of caution and replace it more often rather than less. This will help to ensure that your AC unit is running as efficiently as possible and that your air quality is the best it can be.
Just make sure not only do they match what was on your unit before – but also make sure you’re getting the right size. An oversized or undersized filter can cause problems as well.
Final Thoughts
A dirty air filter can cause a lot of problems for your AC unit, including decreased efficiency, frozen coils, and even a complete shutdown. In extreme cases, it can even cause your AC unit to catch fire.
So it’s important to keep your air conditioner’s filter clean and replace it when necessary.
Changing your AC filter not only helps to improve the quality of air in your home, but it can also save you money in the long term.
If you’re not sure how often to replace your filter, it’s always best to err on the side of caution and replace it more often rather than less. This will help to ensure that your AC unit is running as efficiently as possible and that your air quality is the best it can be.
