One of the largest parts of your HVAC system is the ductwork. Ducts are sort of like the branches of a tree, routing air to each room in your home. Because your ducts are not visible, they can be easily ignored and not maintained. Keeping your ductwork in tip-top shape is crucial to the health of your HVAC system overall. Make sure that you have your ducts cleaned on a regular basis to extend the life of your HVAC system and improve indoor air quality.


Your furnace may be something that you have just started to use with the recent drop in temperature. It does a great job at turning electricity or gas into heat. It is typically located in your basement or attic and can look like a metal cabinet. Your furnace should be checked on an annual basis to ensure everything is safe and there are no leaks present.

Heat Exchanger

This is located in the furnace and looks like a metal tube. It transfers heat between the metal and the air flowing through it. This helps to heat your home and is one of the most important components of your HVAC system. These are just a few of the important components located in your HVAC system.
