Thank you to Don of Cook's Heating and Cooling of Lake Zurich for their quick fix on our inoperative furnace. They had us up and running within 2 hours! Thanks so much guys, you're awesome!

Cook is a good old fashioned family business. I genuinely feel that they appreciate my being a customer. Don assisted us with an air conditioner issue earlier this year with a very novel solution. Recently, I talked to Don again to report a furnace problem. Several times during the call he proactively addressed issues concerning my family's safety. During a cold spell recently, where I imagine everyone's furnace breaks down at the same time, Cook Heating found time to fit us in fairly quickly. A very polite gentleman arrived at our home on time, quickly diagnosed the problem and got us back up and running. As with the air conditioner issue earlier this year, the price was very fair, the area was left neat and clean and a thorough explanation of the problem and preventive measures was provided. As a resident of Lake Zurich for 18 years, I've had many people in my home quoting and performing various repairs and installations. Cook Heating & Cooling provides me with a level of comfort and confidence that I rarely enjoy anymore.

Highly recommend. They find the root cause of the issue not just replacing stuff

I was so happy that Don came out on  New Year's Eve and quickly assessed and corrected my furnace issue. Also spent time explaining the workings of it, and never tried to sell me anything! Thank you Mr. Cook, for being knowledgeable, honest and highly professional.

Cook's is a fantastic company! They rescued us at our business in Wheeling during a cold snap and have serviced our home units as well. They also installed a new unit at my family member's home. I have referred them to several people who have used them and are now happy customers. Every time one of their people arrive, they are on time, courteous and tidy. They never leave a mess, even after installing new units. We shall continue to use them and refer our friends and neighbors.

Don Cook and Cook's Heating & Cooling deserves the highest rating possible. For many years he has serviced our heater and air conditioner. Don is a genius at repairing equipment. He always looks for a creative solution as opposed to other companies who quickly suggest costly replacements. He is quick to schedule an appointment. When his team arrives they are clean and professional. Don Cook stayed longer after the job to make sure his customer fully understood how operate the new system. I have recommended Cooks Heating to many people and will continue to do so. With Cooks Heating you will get honest , affordable and the highest quality service each time.
