Using the Wrong Filter Type
What type of filter should I buy for my furnace? This is a very common question in Schaumburg, IL. There are so many different types of filters in Home Depot, Menard’s, Amazon, Lowes. How do you know which one is right for you? The physical size of your filter (ex 16x25x1, 20x25x4) will always be the same. From there you have different thicknesses of filter, from a thin fiberglass filter all the way up to a 3M MERV 13 allergen filter and everything in between.
The MERV rating is what you’ll look at to see how dense the filter is. The higher the MERV rating is, the smaller the particles / allergens / dust it will catch. Even though a higher MERV rating may sound like the best option because it will help you breathe better air, it does not allow your furnace to breathe the way it was designed to.
Asking your HVAC professional is always best to understand what the highest MERV rating is you can use without damaging your HVAC system. As a quick rule of thumb, we recommend getting a filter that costs around $4-$7 per filter. That is usually a good mix between filtration while still allowing your furnace to breathe properly.
Dirty Flame Sensor
What is a flame sensor? Just like it sounds, the flame sensor’s job is to detect a flame and make sure everything turned on the way it was supposed to. The flame sensor is meant to keep you safe. Over time and hundreds of furnace cycles, it gets buildup of carbon and can no longer detect the flame properly.
Solution: Simply remove the flame sensor and wipe it down with some very light sandpaper or steel wool and you’ll be back up and running.
Weird or Loud Noises
Furnaces make all kinds of noises. There are two motors that turn, on plus the burners. Some of these sounds you have probably become accustomed to, but there are some noises you’ll want listen out for.
If you hear any kind of high-pitched noise, grinding, the furnace turning on and off, etc., these may be early warning signs that a more serious (and more expensive to fix!) issue is on the way.
Another common noise is a loud boom when the furnace first turns on and/or off. This is caused by the ductwork expanding and contracting with the air moving through it. If you have “Duct Boom” there are some economical options to help make that noise go away.
Solution: Call your Schaumburg HVAC expert right away!
