Frequently Asked Questions

Where is the air filter on an American Standard AC unit?

In most American Standard AC units, the air filter is installed within the return air duct or inside the blower compartment of either the furnace or the air handler. Since this can vary with models, it is best to consult the owner's manual or a professional about its actual location.

Are higher-quality air filters worth it?

Better quality air filters are worth every investment dollar spent. They filter smaller particles and improve indoor air quality. In fact they can even extend the life of your HVAC by keeping it cleaner. You just want to make sure you get a filter that can work inside your HVAC so you don't cause any restrictions in airflow.

How do I find my AC filter size?

You can find your AC filter size either by looking at the printed dimensions on the existing filter or searching for them in the user manual for your HVAC unit. If there are no markings on the filter or if you can’t find the user's guide, then you may measure the filter slot against the length, width and depth.

Is it OK to buy cheap air filters?

While inexpensive air filters may seem like they save money upfront, they usually cannot filter as well or last as long. This can also impact your indoor air quality and increase the load on your HVAC. These conditions lead to high energy bills and expensive maintenance costs.

Where are my air filters located?

They are commonly installed in return air ducts, which may be located in walls, ceilings or even near the HVAC itself. In central air units this filter is often inside the blower compartment or air handler.

How many filters does an AC unit have?

Most residential AC units have at least one air filter. It is located in the return air duct or even the blower compartment. Other systems, however, particularly larger or more intricate setups, might have more than one filter just to make sure there is adequate filtration of the air.

What type of air filter is best for HVAC?

The general best type of air filter for HVAC depends on specific needs in a given household. Taking into consideration various factors like air quality, allergies and compatibility with the HVAC. HEPA filters are great for filtration but not necessarily compatible with every system, since some restrict airflow. Pleated filters fall somewhere in between and have relatively good efficiency and better airflow.

Is MERV 11 too restrictive?

A MERV 11 filter offers a high level of filtration. They capture finer particles like pet dander and dust mites. However, it is so greatly restrictive to some HVAC that it could cause reduced airflow with possible system strain. You're better off checking compatibility for this rating in your HVAC manual or by a professional.

Is MERV 4 good enough?

The filter with the MERV 4 rating is chiefly used in basic filtration and is adequate for filtering larger particles such as dust and pollen. While it is superior to no filtration at all, the filter is not sufficient in homes. Where some allergic individuals or locations demand high air quality.

How do I tell what air filter I need?

To find the right air filter for your HVAC system, check the present filter or see its size and MERV rating. Or refer to the manual from the HVAC unit. If these are not an option, consult with a professional.

What is the most common HVAC air filter size?

Standard sizes for HVAC air filters are 16x25x1 inches. But they can be very different depending on the system and its manufacturer. It is always going to be important to check the size of the existing filter or the manual of the HVAC unit to which the filter will go.

Does the AC filter go in the top or bottom slot?

Its placement will depend on the design of the particular HVAC unit. Commonly, it needs to be placed in the slot from where air enters the system. Either at the top or bottom. For more accurate information refer to your unit's manual or consult a professional.
