About Us

We're Engineering Air... ®

Back in the Day...

Waldron of Maryland, Inc. began in Baltimore in 1980 as a small spin-off of Waldron, Inc. of Alexandria, Virginia which was already an established manufacturers' representatives firm of "air side" products.

We did business uniquely different from most rep firms by stocking quality air products on a big scale not seen before. Eliminating the 4 to 6 week product lead times that were common in the industry made our customers happy.

We became a stocking manufacturers' rep; the independent hybrid that combines the expertise of the direct manufacturers' representative with the stocking capabilities of the wholesaler/distributor.
The manufacturers we stock are first class national and international manufacturers with a proven track record of quality and durability.


We have scaled up our stocking operations to satisfy our customer's needs.

If you visit one of our warehouses today- one of the keys to our success is obvious. Our loading docks are usually a beehive of activity as trucks of all sizes are coming and going, loaded up with HVAC air products.

We have a big new stock catalog. We have big warehouses. We have big manufacturers backing us up; but we are still a small 34 year old company of 15 dedicated people with hundreds of combined years of experience in the air products business. We know air products from Airtights to Zephyrs.

Now we bring you our entire stock catalog onto the web for your selection and ordering convenience.

About Us Is Also About Them.

Our manufacturers have dynamic design and production people teaming up to bring the newest and best products to market and then providing the engineering and application support necessary to help us help you.

All successful reps have great manufacturers behind them. Our manufacturers have their own stories of determination and perseverance that we love. Here are a few examples:
