Today, we remember September 11, 2001, and the nearly 3,000 lives lost that day.

We honor the courage of the first responders who ran toward danger, the families who lost loved ones, and the countless heroes who answered the call to serve.

25 years later, we remember. We honor. We will never forget. 🇺🇸

Last week, we had the honor of attending the unveiling of a beautiful new mural in downtown Frederick celebrating the city’s first Black educators. 🎨

Created by artist Raphael Blanco and Mountain City Elks Lodge #382, the mural stands on the site of Frederick’s first African American school and honors three pioneers: John W. Bruner, Maurice Reid, and Esther Grinage.

Warner Service was proud to support this project and help keep their legacy alive for generations to come.

Check out the before and after photos of our latest Weil McLain steam boiler installation! The old boiler, which we installed 23 years ago, had seen better days. After a leak caused the heat exchanger to rust, it was time for an upgrade. We're thrilled to have upgraded our customer to a brand-new Weil McLain steam boiler that will last for years to come! 🔥🔧

Here’s what a true duct cleaning looks like ➡️

At Warner Service, our duct cleaning is more in-depth than just a vacuum. We use Roto Brush equipment with a rotating brush + drive shaft that cleans the sides of your ductwork while vacuuming out dust and debris at the same time.

💨 The result:
✅ Cleaner air
✅ Less dust in your home
✅ A healthier environment for your family

Results speak for themselves — just look at these before & afters! 🔥

Daikin or Goodman — we’ve got you covered! ✔️ While we typically install Daikin systems, we also proudly install Goodman HVAC systems, which are part of the Daikin family. For this project, our team installed a brand-new Goodman system along with a new lineset, disconnect, and thermostat to ensure peak performance and year-round comfort. ❄️🏠
