We’ve been providing the highest level of comfort since 1980!

We are family owned and have loved the privilege of bringing comfort to other families for over 35 years.

Quality air conditioning service, in a timely manner…Every time.

Family owned and operated, Aero Designed Systems serves the communities of Lakeway, Georgetown and Sun City, Texas, and the surrounding areas with dependable, top-of-the-line heating and air conditioning service, featuring systems from the nationally recognized brand Lennox. We strive to deliver quality work, in a timely manner…every time.


We treat every customer as if our company depended on your business—because it does! As a part of our mission to serve you best, we have become Lennox Premier Dealers, NATE Certified, and accredited through the Better Business Bureau.

Many companies claim to be the best, but what does “the best” really mean? Some people search for the best price, some search for the best products, and some search for the best quality. Here at Aero Designed Systems, we strive to offer the absolute best air conditioning services, products and price—with no corner-cutting, no unnecessary costs, and no dishonesty. When you give us a call to handle your HVAC needs, they will be handled in the very best manner possible, guaranteed!


Air Conditioning ServiceWith ever-evolving technology, it’s often hard to determine the best products available. That’s why at Aero Designed Systems, we offer Lennox. Lennox has strived to continue being leaders in the air conditioning industry, introducing units that communicate with each other, control humidity, and can be controlled from anywhere you have a smart device. We sell Lennox because we believe they are the very best.


The Lakeway area has been our focus since Aero’s doors opened in 1980, with our main office located right here in Lakeway, Texas. We then expanded to our second location in Georgetown, which also serves the community of Sun City, Texas.

We not only want to grow our business, but also to grow our many partnerships with the local community. We have supported many local activities, such as the Lake Travis High School football team, the Hills Country Club golfing events, and many other community events. We love this community, and plan on serving it as long as we are in business. You and this community are our priority, and we hope to be able to not just tell you, but show you in the future!

We purchased Aero Designed Systems in 2000 and have enjoyed getting to bring comfort to your homes since. Before, we owned another HVAC company in the Houston area but made this move for our family and have loved getting to know yours!

Paul Slack

I’ve been working with my dad in the HVAC business almost since I could say Air Conditioning and Heating! I have loved getting to know everyone and having the privilege of bringing comfort to each of y’all’s homes.

Roger Davidson

Service Manager

I’ve been with Aero since 2005 but have over 40 years of experience. I love working for a company that focuses on family and doing the right thing even in difficult situations. This is why I am a part of this family and why I continue to be!

Heather Morris

I knew the Slack’s before I worked with them from church and love getting to be a part of the family now through Aero. I love getting to talk with each of you when you call in and so look forward to speaking with you if I haven’t already!
