Latest Customer Review: May 20, 2020: (Armstrong 57W79 (old 45695-004) pressure switch) I could not find the part I was looking for at any of the local HVAC stores. One quick online search brought me to Keith's and using the website made it extremely easy to find the part. I called the store and they were very helpful. I got the part from Keith's delivered to my house before I could get a call back from one of the stores on whether not the part was available for me to order. I will use this store for all future purchases. Good work! Eric
