Great news! Austin Energy partnered with Velocity Credit Union have extended this awesome opportunity to replace your old, existing AC system with a high efficiency rated new AC system and whole house weatherization with zero percent financing for up to 10 years with Austin Energy rebates while making your home energy costs more affordable. This is a limited offer. All new equipment will be registered for a 10-year warranty after full payment of the system is received. And on some new equipment we offer a 5–10-year labor warranty at a nominal cost. A labor warranty allows your parts or equipment warranty to be transferred to a new owner if you are planning on selling home in the future.
