Cornerstone Heating & AIr Conditioning, Inc.

We are a small family owned Company that has been around since 2005 as a company but have served frederick Couty and City for 34 years through various jobs notably Southern States oil Company and Ewing oil Company. I left the ol only scene in 1999 and worked for Mick's Heating & AIr in Thurmont for 6 years. In that time, I ran 99% of all after hours calls and was basically the only one to do oil work besides 1 other guy. After 6 years of finding a bad boiler, pricing it, ordering it, setting it up and installing it myself and then taking the check from the customer and give it to the boss. I figured, all I needed was a License and insurance and I'm good to go. 11.5 years later here We are, still in business, although slow at the moment, its hard to run a no heat call when is 76*F outside on the 22, of February!
