Great Lakes Heating and Air Conditioning employs our own installation crews and factory-trained service technicians. Our company is licensed, bonded, and insured. We offer 24-hour emergency service. During working hours our courteous and friendly office staff will respond to your needs. After hours we employ an answering service so you can still talk to an actual person. For your benefit and convenience, we offer comprehensive service and service plans, air duct cleaning, in addition to a new state-of-the-art showroom. When selecting something as important as your family's heating or air conditioning needs, we invite you to try it before you buy it. Since typically these units can last up to 20 plus years. You owe it to yourself to stop by in person and try it before you buy it. Simply fill out our appointment form to schedule a visit.
