ASM MECHANICAL COMPANY invites you to improve year round comfort while significantly trimming your energy bills. Take a look at the unmatched benefits of an electric heat pump. These compact, quiet, and rewarding systems provide both heating and cooling. During the summer, the heat pump acts a lot like a central air conditioner but exemplifies dehumidification and efficiency for superior comfort and cost savings. When the weather in Chicago, IL and surrounding areas cools off, the unit reverses operation, finding ambient heat in the outside air to keep your home nice and warm.
