Air filters are essential to maintain good air quality within a home, prevent fires, and decrease bacteria. If your home has a dirty furnace air filter, you may have a higher energy bill, more illnesses, and your home won’t be as comfortable.
When was the last time you changed your air filter? If you don’t know the answer to that question, your furnace air filter may need changing. Keep reading for 8 signs that you need to change your furnace filter.
One of the first signs that you need to replace your furnace filter is the color of the filter. While a new filter is usually white, an old filter will be gray and covered in dust.
If the filter has a large amount of dust on it, that dust will get into the air you breathe. A buildup of dust is the easiest way to tell if you need a new furnace filter.
Higher Energy Bills
Have you noticed that your electric bill has been higher recently? While there could be several different reasons, one reason could be your air filter.
When air filters become clogged or dirty, they have a much harder time circulating air. If the air is not circulating well, the temperature inside your home is not well-regulated. This will cause your furnace to run harder to make up for the poor circulation.
When your furnace runs constantly, the energy bill will be much higher than it was in the past. If your energy bill is expensive, try changing your air filter to see if it saves you money.
Investing in a new air filter is a small price to pay to save money on your monthly bills. You can even buy discount filters c3045 to save you even more money.
Is there a burning smell coming from your furnace? If so, you may need to change your air filter. A burning smell can be concerning because you don’t want a fire to start in your house.
When you haven’t changed your air filter in a while, the dust can collect on the filter and create that burning smell when it gets too warm. Dust and lint can be an extreme fire hazard.
If you notice a burning smell, start by changing your air filter. If that doesn’t solve the problem, turn off your HVAC system and have a professional look at the system immediately. You may need HVAC repairs.
Lack of Warm Air
Another sign that you may need to change your furnace filter is if the HVAC system is no longer blowing warm air. When there is a buildup of debris around the air filter, the airflow is restricted.
Restricted airflow causes the air that does make it through to be cooler. That is because it takes longer for the air to pass through. Because the air is cooler, you may feel uncomfortable in your home.
A lack of warm air could also be a sign of HVAC issues. If changing the air filter doesn’t fix the problem, you should have your furnace examined.
Furnace Running More
Another common problem related to needing a new air filter is a furnace that is running more often. As mentioned earlier, furnaces have to work extra hard if there is a buildup of lint.
Because less air can get through the system, your furnace will have to run harder to change the temperature in your home. If it seems like your furnace is running nonstop, buy a new furnace filter online to see if that solves the problem.
Getting Ill More Often
If you have noticed yourself or family members getting sick more often, your furnace air filter could be to blame. When the air quality in your home is bad, you are more likely to have allergies and get sick.
People that have asthma may have worse symptoms and more frequent asthma attacks. This can be a life-threatening situation for those with severe asthma.
If you have found yourself sneezing more often than usual, do yourself a favor and change the furnace air filter.
More Dust in Your Home
Have you noticed more dust in your home? If your air filter is not performing well, you will notice a buildup of dust on your furniture.
The air filter’s job is to collect dust and prevent it from flowing through the filter. When the filter is clogged, the dust has nowhere to collect, and it flows through the filter. Sometimes, the dust will continuously cycle through the HVAC system.
If you notice more dust than normal or have dust allergies, changing the furnace filter could help solve the problem.
Age of Current Air Filter
When was the last time you changed your air filter? If it has been more than 3 months, you need to change it.
You should check your air filter every month to see how dirty it looks. While you should change it every 3 months, it may need to be changed every month in the middle of winter. This is because the HVAC system runs more often to keep the house warm.
