Advance air & Heat
“Our customers and employees are the two most important components of our business. Without either one, there would be no business.” - Karen Lamy DeSousa, Owner & President
How can you tell the difference between a good company and a great company? We think the formula is creating an environment where both the employees and customers not only stay but refer their friends.

Experience the Difference

Employee Longevity

Another Advance Air difference maker.
Some of our employees have been with us for well over 20 years, with the average employee having been with us for over 12 years. 
Most of our employees are referrals from existing employees.
Just as with clients, we have also built our business from developing trusting relationships with our team members.

Customer Retention

Some of our clients have been with us since the beginning. A lot have been with us for over 2 decades. We do not do a lot of marketing as the bulk (Over 85%) of our clients are referrals from existing clients.
Similar to our employees, we have built our business on the trusting relationships we form with our clients.
