I have an old Lennox furnace model Gh6-120c-1. I need to know what type of filters does it use?
The Lennox GH6-120C-1 furnace uses a standard 1-inch thick filter. The filter should be replaced every 1-3 months, depending on the level of contamination in the air and the frequency of use of the furnace.
To determine the correct size and type of filter for your Lennox GH6-120C-1 furnace, you will need to refer to the owner's manual for your specific model. The owner's manual should provide information on the recommended filter size and type, as well as instructions for replacing the filter.
In general, it is recommended to use a high-quality filter that is capable of removing contaminants from the air, such as dust, pollen, and other allergens. There are several types of filters available, including fiberglass, pleated, and washable filters.
To replace the filter, you will need to locate the filter compartment on the furnace. The filter compartment is typically located behind a panel or door at the front or side of the furnace. Once you have located the compartment, you can remove the old filter and install the new one by following the instructions in the owner's manual.
If you are unable to locate the owner's manual or are unsure of how to replace the filter, it is recommended that you contact a qualified HVAC technician for assistance.
