Have a friend, family member, or colleague who could use a new heating or cooling system? Send them to Dugan Air and you could find your own little pot of gold! When your referral becomes a new customer and installs a new system, you’ll receive $100, while they’ll receive $200 off their new system. It’s a win-win way to share the Dugan Difference, help someone you know find better comfort, and earn a little something for yourself along the way.
