After looking at the unit, Caleb, the service tech, told me I need to replace the whole system abd it would be 28k for a new furnace and a/c. Luckily I called for a second estimate. M & B inspected the unit and replaced the controller. The parts and labor were $350.00. If precision gives you an estimate, get a second opinion. They did however refund the price of the service call.

I Google heating and cooling places by me and Dykstra came right up with 4.5 stars. I made the call. Within 2 hours Zack shows up. Very kind and professional!! 6 stars for Zack - he diagnosed the issue right away and explained everything. I'm only giving 4 stars overall because I couldn't get the unit installed same day or even next day. Wednesday Ray and Victor installed the new unit. Nice guys. Thursday I get home and its freezing in my house. I notice that the thermostat reads 64 but set to 70. I call Zack, my saving grace!! He calls the office and they send Casey (sp?). Casey showed up that afternoon and found that a wire had shorted. Quick fix and he was on his way. I do recommend Dykstra. There is some confusion with the answering service and a merge going on, but I was able to talk to someone that knew what was going on.

My AC was blowing warm air and my husband was at work. I researched mailers, yelp reviews, and called a couple of heating and air conditioning services. I'm calling the advertised after 24 hour emergency phone lines and leaving messages with no reply. Finally, Windy City Mechanical answers the phone and inform me they could send someone out. Luckily, the guy lives right around the corner and is there in minutes. He walks up introduce himself and proceeds to inspect my AC unit. We go in the house and he informs me of the options available. He sat in my house for an hour sweating bullets with no complaint or discomfort answering all my questions and my husband's via phone. My husband and I decided to replace the entire AC unit for various reasons including the age of the unit. Tom educated me on our options and explained the units fairly and without bias towards a more expensive unit. As a matter of fact, he determined we didn't need the larger unit we currently had and a smaller (less expensive) unit would suffice. Nevertheless, his guys were there the next morning to replace our AC unit. They were prompt, professional, and efficient. I would highly recommend Windy City Mechanical they gave us a great deal!

When I asked what Windy City was going to do about it, you said nothing. That's when I got upset. And why on earth would I take any of your calls AFTER you had said your company was going to do NOTHING. This conversation is over. You and your company have a long way to go with customer service.

For example, having the air conditioning and heat going on at the same time would eventually cause risk of wear and tear the heating & air condition, causing us to have a new unit installed, being professionals that should have never happened. Also, when taking out the old furnace, you used no covering and left pieces of stuff everywhere that they didn't clean up and a mark on my wall that will not come out. Perhaps if the worker concentrated and spent more time on the job rather than being unprofessional, installing the furnace job would have been done correctly in the first place. Approximately we have spent roughly $11,600.00. It's unnecessary getting the service done from this company in the future. We would not recommend this company to anyone.
