Do you ever experience low air flow in your house? There are many potential causes for this, so let's look at five of them.

A dirty air filter can be a major issue. If it's too clogged up, it restricts the flow of air and makes your HVAC system work harder, reducing efficiency. It also makes it harder to remove pollutants from the air. Depending on how much your system runs, it's best to clean or replace your filter every 30-90 days.

If you have a filter that is too efficient, that can cause low air flow too. Check the filter's Minimum Efficiency Reporting Value (MERV) rating - this is a measure of how effective the filter is at trapping particles. The higher the rating, the fewer dust particles and contaminants that can pass through, but it can also mean your HVAC system has to work harder.

Your ductwork could be the culprit. If the air has to travel too far or through turns and bends, it makes it harder for air to get where it needs to be. Other issues like blockages, disconnections and holes can also reduce air flow.

Closing off air vents or blocking them with furniture is another common cause. It might seem like a good way to save energy, but it can make your HVAC system work harder and cause your energy bill to go up.

Finally, an air conditioner that's the wrong size can cause low air flow. An oversized unit won't run for very long, not giving it enough time to dehumidify your house, while an undersized one will run constantly and push your energy bill up. A correctly-sized unit will work efficiently, cooling your home without overworking your system.

Nobody wants to deal with a dirty air filter. It can be unappealing to look at, often coated in gray or tan dirt that flakes away when disturbed. But if it's not dealt with, it can cause serious problems - even decreasing the lifespan of your HVAC system by half or more.

Your air filter is responsible for catching particles such as dust, pollen, pet dander, and even bacteria and viruses - depending on the filter's efficiency. So, to avoid any potential issues, it's important to recognize the signs of a clogged filter. Check for an increase in dust, a gray or filthy filter, a change in your energy bill, and a longer cycle in your HVAC system. All of these can lead to the recycling of air filled with allergens, a rise in allergies, higher energy costs, bacterial growth, and even the destruction of your HVAC system.

It's always best to be prepared for the worst. Stock up on replacements and choose high-efficiency filters for extreme seasons to keep the air in your home clean. This way, you can protect your HVAC system and your family's health, while avoiding any costly problems in the future.

Indoor air quality is often worse than most people realize, with pollutants ranging from two to one hundred times higher than outdoor concentrations. Factors such as ventilation, airflow, humidity, temperature, and various contaminants like dust, mold, and pesticides all play a role in air quality.

Air filters are a great way to improve air quality and reduce the impact of allergies and asthma. However, not all air filters are created equal. Fiberglass filters are good for removing larger particulate like lint and pet hair, but have a low resistance to airflow. Pleated filters have deeper pleats and can capture smaller particles; they also have the added bonus of being biodegradable or recyclable.

When it comes to air filter longevity, pleated filters last longer than fiberglass. To maximize your air filter's life, it's important to change it regularly. For fiberglass filters, this means every 30 days, while pleated filters can last up to three months. Consider factors like the type of residence, air pollution levels, allergies and asthma, and pets when deciding how often to change the filter.

Finally, the frequency of filter changes will depend on your HVAC system usage. If you live in a warm climate and only use your AC or furnace rarely, your filter will last longer. But if you're using it often, you'll need to change the filter more frequently.
