Time For Furnace or AC Installation!

OUR HOLIDAY GIFT to YOU, our neighbors - HARMONIC will give you $300 OFF the purchase of a Armstrong Furnace AND Air Conditioner COMBO, but you must schedule your install in December.

BUT WAIT, THERE’S MORE! There are a ton of REBATES available from ComEd and NicorGas, on top of the Armstrong manufacturer rebates when you select high-efficiency equipment to make your home “SMARTER, HEALTHIER, and MORE EFFICIENT.”


“So don’t wait. Call now!” These offer’s won’t last long. The sale prices and rebates WILL expire. See website for HOLIDAY DEALS.

We have customers who have been telling us that they want to wait until next year. While that may sound responsible, they will pay significantly MORE for their Furnace and A/C install. On average, maybe $1000 more. Plus, losing the available rebates, they may lose another $800 on high-efficient equipment.

We know this is bad timing… but WAITING is a bad idea, and NOT fiscally responsible.
