How To Change HVAC Air Filter?

10th May 2024

HVAC air filters play a crucial role in filtering out contaminants like dust, allergens, and bacteria, ensuring the air in your home remains clean. As filters accumulate particles, their efficiency decreases, which can lead to increased energy costs and reduced air quality. It's important to replace these filters regularly to maintain a healthy living environment.

This blog will guide you through selecting the best air filter for your needs, replacing it, and determining the ideal timing for replacements. Through step-by-step instructions, you will have all the knowledge needed to keep your air clean.

Why Change HVAC Air Filters?

Changing the air filters in your HVAC system is important to maintain air quality and ensure system efficiency. These filters trap dust, allergens, and other airborne particles, preventing them from circulating in your home. A clean filter reduces strain on the HVAC system, leading to lower energy costs and extending its lifespan. Here are the key reasons why changing your HVAC air filters is important:

  • Improved Air Quality: Air filters capture pollutants like dust, pollen, pet dander, and other particles. Regularly changing these filters helps maintain clean indoor air, reducing allergies and respiratory issues.
  • Enhanced System Efficiency: Dirty or clogged filters restrict airflow, forcing the HVAC system to work harder, which can lead to decreased efficiency and increased energy consumption. Clean filters ensure that the system can operate at optimal efficiency.
  • Extended System Lifespan: When air filters are not changed regularly, the HVAC system can become overworked, which may lead to more frequent breakdowns and potentially shorten the system’s lifespan.
  • Cost Savings: Efficient systems use less energy, which translates to lower utility bills. Additionally, maintaining your system well by changing filters regularly can save on costly repairs and replacements.
  • Home Safety: Keeping air filters clean also helps reduce the risk of circulating pollutants and potentially dangerous gases, such as carbon monoxide, especially if the HVAC system includes a furnace.

How Often Should You Change the Air Filter?

The frequency at which you should change your HVAC air filter can vary based on several factors, including the type of filter, the air quality in your home, and how you use your system. Here are some general guidelines:

  1. Standard Disposable Filters: For the average home without pets and with minimal allergies, change your filter every 90 days. If you have a single pet, consider changing the filter every 60 days. For multiple pets or if someone in your home has allergies, you might need to change it every 30-45 days.
  2. High-Efficiency Filters: These filters are designed to trap more particles and can generally last longer. Depending on the manufacturer's recommendations and your living conditions, you might change these every 6 to 12 months.
  3. Usage and Environment: Homes in dustier environments or those used more frequently (such as during peak heating or cooling seasons) may require more frequent changes.. Additionally, if your area experiences high pollen counts or if there is construction nearby, you may also need to replace your filters more often.
  4. Household Factors: Homes with smokers or multiple pets may need to change their filters more frequently due to higher amounts of particulates in the air.

It's a good practice to check your air filter monthly and replace it if it looks dirty. Waiting too long can cause your HVAC system to run less efficiently and potentially damage it over time.

How To Change HVAC Air Filter? A Step By Step Guide

Changing your HVAC air filter is a straightforward maintenance task that can significantly improve the air quality in your home and the efficiency of your system. Here’s a step-by-step guide to help you efficiently replace your HVAC air filter:

Step 1: Locate Your Filter

First, identify where your air filter is located. In most residential systems, it will be in the return air duct or in a slot on the furnace itself. In larger homes, there might be multiple filters located in different air returns.

Step 2: Turn Off the System

Before changing the filter, make sure to turn off the HVAC system. This prevents the system from drawing in unfiltered air while you are changing the filter and ensures your safety.

Step 3: Remove the Old Filter

Carefully slide the old filter out of its housing. Most filters will have a size and airflow direction indicated on the edge. Note these as you will need this information when inserting the new filter.

Step 4: Check Filter Size and Type

Check the size and type of the old filter. It’s important to replace it with the same size and recommended type to ensure that your HVAC system functions properly. If you're unsure, take the old filter with you to the store when purchasing a new one.

Step 5: Insert the New Filter

Take your new filter and make sure the air flow arrows (printed on the side of the filter) point towards the furnace or air handler. Slide the new filter into place, ensuring it fits snugly without any gaps around the edges.

Step 6: Dispose of the Old Filter

Dispose of the old filter according to local regulations. Some filters can be recycled, so consider checking if recycling options are available in your area.

Step 7: Turn the System Back On

Once the new filter is securely in place, turn your HVAC system back on. It's a good practice to check the system briefly to ensure everything is running smoothly and that the filter is in place.

Step 8: Regular Checks

Mark your calendar to check and replace the filter regularly. As previously mentioned, the frequency of replacement will depend on several factors including your living conditions and filter type.

By following these steps, you can ensure that your HVAC system remains efficient, prolonging its life and maintaining good air quality in your home. Regularly changing your filter is a simple yet effective way to reduce energy costs and prevent costly repairs.

FAQs

1. Where Are HVAC Filters Located?

HVAC filters are typically located in the return air ducts of your home, near where the air is drawn back into the HVAC system. You can often find these home air vent filters in a slot on the furnace or air handler itself. In some homes, especially larger ones, there may be multiple filters situated at various return vents. Always ensure the system is off before checking or replacing these filters to maintain safety.

2. What HVAC Filter Should I Use?

The type of HVAC filter you should use depends on your specific needs for air quality and system compatibility. For most homes, a pleated medium-efficiency filter offers a good balance between cost and performance. If you have allergies or pets, consider a high-efficiency particulate air (HEPA) filter for superior filtration. Additionally, using an air filter cleaning kit can help maintain reusable filters and extend their lifespan.
