Feel free to claim one for yourself via this post. We are more than happy to help you keep things affordable.

The coupons are $50 off a service repair and $500 off a qualifying furnace replacement. What that means is Nicor is giving $300 off high efficiency furnace installations and we will give you another $200 for the promotion. The Nicor portion expires May 31st of 2014 so don’t miss out.
