As we head into this long weekend, we stop to remember that Memorial Day is not just a holiday, but a time of reflection and gratitude for the brave men and women who made the ultimate sacrifice for our country.

In honor of those who gave everything for our freedom, Duncan Heating & Air Services will be closed Monday, May 25th.

We are forever grateful to our fallen heroes and extend our deepest thanks to all Gold Star families. 🇺🇸

God Bless the USA 🇺🇸
