I scheduled an appointment for an air conditioner cleaning/tune-up about a month in advance. Jill sent out reminders so we knew when he was going to show up. I asked that this could all be done contact free due to the pandemic and it was. The air conditioner was cleaned and all is well. It has been great to work with Jill and Glenbrook Heating over the years. Thanks.

We returned to this company after living out of state for a number of years. The service is friendly and efficient. Nick kept in touch because he was running late–much appreciated! He also explained things and, in general, was very professional. We look forward to your service for many more years!

Glenbrook Heating & Air Conditioning has serviced our home for almost 20 years. Prompt, professional, and reasonably priced, they provide the perfect hat trick to meet all our heating and AC needs. On top of that the entire Glenbrook Heating & Air Conditioning team is friendly and informative.

James S. on 08/07/19

Glenbrook consistently provides top service in the annual checkups. The main office is also responsive and helpful. We’re glad we decided to get our furnace and air conditioner from them three years ago.

Joan S. on 07/10/19

I’ve purchased both HVAC & AC units and now a sump pump from Glenbrook Heating & Air Conditioning. They have been incredibly fair, honest, personable, & professional both installing my new equipment and servicing my past equipment. I would recommend them to anyone that asks. It’s hard to find good quality customer service for anything anymore and I thank Brad & team for a refreshing experience time & time again!

Brad is very courteous and friendly. He was on time and does a great job with keeping our heating and air conditioning units in excellent condition. During this cold winter, we were very comfortable.

They called to let me know they were on their way, arrived on time, did the job quickly and neatly, and the service person was very pleasant.

Peter B. on 05/07/19

We first moved to Northbrook in 1973 and Glen Brook heating has serviced us ever since. . . It was and still is a family run business which treats their customers with good quality service and fair prices. We would not have stayed with them through 5 moves if we did not depend and trust them.

Last November Glenbrook replaced our furnace and did a great job. This week they finished the job by adding a new A/C. Dominick did a great job, he explained what he was doing and why. The job was completed quickly, and was well done. Just in time for summer. Thanks to you all for years of excellent work.

Glenbrook Heating & AC is great. I really enjoy working with Jill, and the technicians – Dominick and Nick are the two I have worked with — are always prompt, thorough, and answer my many questions. Keep up the great work.

Dear Brad,

This is to thank you for your quick installation of my new water heater. It means a lot to me.

You and your dad should be commended for your prompt and business-like way of conducting your business. I made the initial call to Fred around 9 a.m. and magically, there was a new water heater (working) before noon!

Usually, we wait hours or days for someone to show up when we need help. It’s worth everything to find service like this.

Betty H. (Glenview)

Fred and Brad,

Thank you so much for your prompt attention.

Marla S. (Glenview)

Dear Brad,

Thank you for the beautiful job you did in the basement! I really appreciate the thoroughness and care by which you put the whole thing together! It is always a pleasure to do business with you and your dad. Please send regards to him. As always, he is a life saver.

Terry B. (Glenview)

I appreciate your service and fine work.

Thanks for stopping over on Saturday to check by boiler during the deep freeze. You’re the best!


Fred, Brad and Jill,

Thank you for such wonderful service. You all have been so helpful. The installation was flawless and we love how well the furnace works. What a difference! See you in the spring for our annual cleaning.
