As old as the HVAC industry is, things are always evolving. We have had a few calls lately of the furnaces shutting down because of restricted air flow. Having a dirty filter is a common reason for your furnace to shut off if you weren't already aware. Lately, however, we have pulled filters out that look perfectly clean, making us dig deeper and checking static pressure. Static pressure is the air pressure on the return vs supply side of the heat runs. What we have found is that scent diffusers are causing the filter to get blocked up by the chemicals being released into the air that gets pushed into your filter restricting air flow. Professionally we are not a fan of these types of chemicals as they are full of chemicals that are not good for our lungs, adding harmful chemicals into the environment you live in. If you are trying to remove smells in your home, consider whether duct cleaning, uv lighting or new carpeting is in order. We do not do duct cleaning as typically it is not necessary but if the smells are lingering in the ductwork it would be an option to look at. UV lighting will, over time, remove smells in your home that is airborn.
