Why a Lennox Furnace Pressure Switch is Necessary

I recently experienced an issue with my Lennox furnace where it kept turning on and off without actually heating up my home. After doing some troubleshooting, I discovered that the pressure switch was faulty and needed to be replaced. This experience made me realize the importance of the pressure switch in a furnace.

Firstly, a Lennox furnace pressure switch is necessary because it ensures the safety of your home.
