I know that I need a new filter. How do I find the brand, series name or model number, and the type of equipment I have?Post created: 2014-01-06 Type of Equipment: Furnace Views: 79

I know where the furnace is located: the unheated basement (it is currently -25 degrees outside). The brand of my thermostat brand is Lux. I wonder if it is possible for you to tell me exactly where to look for the necessary information on the apparatus so that I can then purchase the proper filter.

Unfortunately, I may not have an easy answer for you. Here are the two easy answers I can think of:
1. Do you have a manual for your furnace? If so, the information on which filter you need is likely inside.
2. Can you call the HVAC contractor that installed or services your furnace? They may have a record of what type of furnace you have. (They may even be able to tell you what filter you need.)
Assuming that the answer is "no" for both of those questions, you'll need to go down into your crawl space. (The brand of thermostat doesn't necessarily tell you anything about your furnace.) That's probably not the end of the world, because, short of asking your contractor to come and replace the filter for you, you're going to have to go into the crawl space to swap filters anyway.
Before you go to the crawlspace, grab a tape measure, a piece of paper and a pencil. You'll probably want to measure the width of the furnace cabinet while you're down there, and you'll want to write down the brand name, series name, model number, etc. (You could snap a picture with a cell phone too -- that might get you in and out a minute faster.)
Most manufacturers put their brand name -- and often the model number and series -- on the front of the furnace. Sometimes the brand will be on the front, and the model number will be on the side.
If you can figure out where the furnace filter is located while you're on your first trip to the basement, you might as well take a look at that too. Many times the measurements are listed on the side of the filter.
Hope that helps, please feel free to write what you learn as a reply to this post, and we'll try to get your sorted out!
