When is the Goodman furnace filter replacement necessary?

Filters are fundamental components of the furnace, and you need to check them and even replacing regularly. But what’s the most appropriate method to know that your Goodman furnace requires replacement? Luckily for you, some signs will inform you about the necessity of replacing the Goodman furnace filters:

1. You get sick

Filthy furnace filters can affect your health. When we go from one season to another, sinus issues, allergies, and various health conditions may develop. However, if you get sick and unstable right after running the furnace, the indoor air’s low quality could be the culprit. Unless you replace the furnace filters, your health condition will linger and cause aggravated health issues.

2. The utility bills get higher

When the utility bills increase, all of a sudden, clogged and dirty filters can be the causes. As a matter of fact, furnace filters that require replacement cause increased bills most of the time. We know that it’s tricky to keep an eye on energy consumption, especially with fluctuating temperatures, but your bills won’t go unnoticed. You will be able to save up to 15% on your energy spending when replacing the furnace filter.

3. The furnace runs for a longer time, but it produces less heat

Does the furnace need more time for heating the home latterly? When the furnace needs more time than usual to heat, some dirty filters could be the reason. Damaged and blocked filters affect the furnace’s proper operation, which requires more time to be effective.

4. There’s a burning smell

When the blower motor or the filter overheats, you will be able to feel a burning odor coming from your Goodman furnace. Your furnace requires the proper amount of air to flow through the system for reducing the risk of overheating. Dirt and debris clog the filters, which blocks the appropriate airflow. Every time you notice a burning smell from the furnace, you should look for filter replacement asap.

5. There’s more dust than before

When your house is still dusty after regular cleaning, the filters on your furnace could play a significant role in it. The dust stays inside the house and keeps coming back. You will have to remove the current filters and replace them with new ones. It’s very effective for cleaning the house, and for improving the air’s quality inside the house. You will still have to vacuum and dust regularly, though.

Are Goodman air furnace filters all the same?

Goodman air filters furnace filters come in standard sizes and can be used on other brands, as long as they’re the same size.

You will find several options for various Goodman furnace filter sizes, and some are pricier than others. Most filters should last for at least six months, and replacement is needed all the time.

What are the Goodman furnace filter sizes?

16×22”, 16×25”, 20×20”, 20×22”, 20×25”, and 20×24” are the common sizes for Goodman air filters for your furnace.

Can you effortlessly figure out the size of the air filter for your furnace?

You will still need to check the actual dimensions of your filter. Air filters come with a nominal size, which is typically a round number. Filter with actual size 15 ¾”x24-3/4″x4-3/8″ will be compatible with 16″x25″x5″ from the same brand but won’t be consistent with a model from another manufactures as the actual sizes could be different.

It’s not complicated to utilize a measuring tape for detecting the dimensions of the filter (the length, width, and depth). Continue with checking the compatibility by model numbers. It’s common for the filter to include a list of models from different manufacturers compatible with the needed filter. Always double-check the manual and the actual size as the numbers are very similar.

Where is the filter placed in the furnace?

There are three common locations for the furnace:

• You may find it in the filter cabinet close to the furnace, between the furnace equipment and the return vent.
• You may find the filter in the blower compartment before the air handler.
• You may also find the filter in return vents inside the home, behind a grill that is easy to remove

Is it dangerous to place the furnace filter in backward?

You should always place the filter in the proper direction for the airflow for several reasons.

• When the air flows in the wrong direction of the filter, you will cause a higher resistance, making the system work harder. Your utility bills get higher, and the furnace’s lifespan gets shortened.
• Installing the filter backward can also make the filter collapse, generating airflow around the filter. Some filters come with wire backing to reduce the risk of collapsing against the airflow. The filter’s primary role is to protect your furnace from dust, and airflow around the filter may affect the furnace.

Should you get an air filter for your Goodman furnace?

Regular furnace filters are appropriate for keeping the system and the ducts working clean, but they won’t improve your home’s air quality. Should you look to have better indoor air quality, you will need to use a media filter. The media filter should come between the blower cabinet and the primary return duct, improving the particle and dust removal even by seven times than the regular furnace filter. Installing a media filter will eliminate anything from airborne viruses to insecticide dust.

Goodman filters are effective for blocking air particles such as dust, pet dander, dust mite debris, pollen, mold spores, and auto emissions. The allergens may affect your health, so using an air filter on your Goodman furnace will improve indoor air quality and reduce the risk of developing conditions related to allergens.

Most media filters can last for a couple of years, and the tight fiber weave may alter your furnace’s regular operation; it will merely be more difficult for the furnace to blow air throughout your house. You don’t just go and buy an air filter for your furnace; it should match your furnace’s capacity, so proper selection is necessary.

Air filters are essential for your HVAC system’s proper operation as they will reduce the number of particulates that collect on the fan motors, the cooling, or the heating coils. According to the manufacturer’s recommendations for protecting the furnace and expanding its life span, you have to replace the air filter.

Why is it more important to check?

MERV (minimum efficiency reporting value) is the value telling about the air filters’ filtration capacity installed on your furnace. The MERV numbering system covers a wide range, from 1 to 20. The higher the MERV rating, the better the capacity of the filter to block the particulates. Fewer particles and other airborne pollutants will be able to go through the MERV filter and onto your Goodman furnace.

Most residential furnaces utilize air filters with a 1 to 4 MERV rating, with basic mechanical air filters less performant on eliminating particulates. However, they may still block large particles from getting to your furnace.

A higher MERV rating means that the filter can block some spores, bacteria, cat and dog allergens, and even a tiny amount of dust mite allergens. Air filters with MERV rating from 7 to 13 will be almost as performant as the famous HEPA filters.

Remember that some residential furnaces may not have enough motor or fan capacity to take the highly-rated air filters. A professional will tell you about the best air filter to use on your furnace. Anyway, only professionals will install the air filters as some changes in the system are necessary.

Don’t forget to check the MERV rating, with MERV eight as a proper value for improving the air quality in your home. MERV 11 and MERV 13 are typically used in commercial applications and households with allergy patients. Only top residential air/furnace filters will come with MERV 15 and MERV 16 ratings.

You may opt for Goodman activated carbon filters, which will eliminate lint, dust, pollen, debris, and dust mite, especially if you’re allergy-prone. Most of these filters will take three months and are useful for blocking some odors.
