Bethany Air Corporation Specializing in professional HVAC services across Maryland & beyond since 1992. We would service HVAC systems for customers that have been "burned” in the past.

I started this business in 1992 out of an old 1980’s van with the help of my wife Denise. We learned very early on in this trade that honesty, integrity and quality are what matters the most in this business. We found those customers were sometimes very standoffish due to the history of prior companies and negative experiences they encountered with them. My wife and I agreed we would never become one of “those companies”. We committed to building strong trustworthy relationships with our customers, most of the time on a first name basis. We took our time to listen to our customers, their concerns and helped them find a solution that worked for them. Through the years this built a solid customer foundation. We are now a company of 32 employees, several reliable work vans, and thousands of customers in our database. We educate and test our employees based on our experience, knowledge, and respect for the business and customers alike. We take pride in building lasting relationships with not only our team at Bethany Air but with everyone we encounter. Finally, we always ask our customers what we can do better and how we can improve their experience with us. This gives us a realistic view of their experience with Bethany Air Corp. and allows us to strive for perfection. We strive to exceed every customers expectations. We have taken into consideration the concerns that have been brought to our attention over the years and have applied each one to our business and employee guidelines. Bethany Air has incorporated several tools and guidelines to ensure our team is knowledgeable, responsible, and respectful. We treat all customers with the same level of importance, respect, and urgency. Bethany Air Corp. has been in business and growing every day for over 22 years because one key difference separates us from the competition; here at Bethany Air, we really do care! Sincerely,

Timothy Zois
President
Bethany Air Corp.
