A&B Heating & Sheet Metal Co.

A&B Heating & Sheet Metal Co. Established 1953 A&B Heating & Sheet Metal Co. Carl was joined by his brother Ralph a short time later. Stay tuned, the story continues...

was founded by Carl Papalia in 1953, a few years after he returned home from serving his country in the South Pacific. In the early stages A&B provided heating, sheet metal, roofing and air conditioning services. While we have since moved off the roof, we continue to serve the Warren County area with professionally trained technicians and fabricators under second generation guidance. The years have written a wonderful story about A&B but it is our loyal customers whom we are thankful for every day.

We don’t get the equipment out much for the 3” gas line work so we have to soak it up when we do. Who knows where am I running this 3” gas machine at?

It’s been a long two days. Hand dug the basement floor for a new sewage ejector system. Thankfully we had the excavator here on day two to dig the trench for the new sewer line.🫠

Tomorrow we replumb the house to redirect the waste to the new ejector. Thursday we restore the basement floor!
