Customer References and Testimonials


To Gilley’s,
You have all been so wonderful to work with and I greatly appreciate the prompt, friendly service!

Kind Regards,
Laura Hills- June 2014

Thank you Gilley’s!!! Right away on the phone Rose gave me an honest upfront pricing on service charge/estimate fee. Technician was fast, friendly, efficient, and clearly honest since it ended up being a minimal repair. Thank You So Much!! Great Company to be trusted!!

Matt and Eric did a great job! The condo building committee was very pleased with how the outside portion of the work turned out. Neat and clean on the inside, too.

To Gilley’s Staff,

Thanks for the rework.  End product meets the vision and nicely implemented.
Matt and Jeff worked hard, obviously know their stuff, and were responsive to my input and suggestions.
Greatly appreciated.

To Gilley’s Manager/Owner,

We would really like to commend the two men who put our furnace in today! The main fellow was named Eric and I’m sorry we didn’t get the younger man’s name who was with him.

They were both so EXTREMELY polite, friendly and helpful!! It has been so ‘rare’ that we have had workers at our home to work on “anything” that were so NICE!! They came on time and got the job done and told us all the necessary information we needed!!

We just want to let you know how nice and helpful they were!! So many people just “complain ” about people who do these jobs….and these two nice men were outstanding!!!  Just wanted to let you know and give them a “thumbs up” on their behalf.

Carole & Bob Kuse – 2013

Dear Sir,

On December 26, 2013 I arrived at my home to find my furnace had stopped working and the water pipes had frozen. I called around to various heating companies only to be told it would be after hours.  I called you and was told that they would have someone here within 30 minutes.  The nicest young man arrived and worked hard to locate and fix the problem in a house that was very cold.  First, thank you for your prompt service. Secondly, thank you for the responsible repairman (Anthony) that came. I will immediately call Gilley’s anytime in the future! I will also recommend you to anyone in need.

To everyone at Gilley’s,

I can hardly express my gratefulness that you were willing to put a furnace in for me last year, when we were freezing, and trusted me to pay it off.  It’s been a long haul….but I did it!!!  I will never forget your generosity and compassion.  I don’t know what I would have done without you!!!

Thanks From the Bottom of my Heart,

Patti Garl – 2012

Mr. Gilley,

It was a true pleasure having Gilley’s replace our furnace, ductwork, and floor structure.  Your company is extremely talented, courteous, considerate, and very thorough.  We are so pleased with everything you accomplished.  For the first time in six years I can breathe easily about the structural integrity and safety of our house.

Thank you so very much for such a superb job!  Your team is wonderful!

Very Best Regards,

Johnni & Karen – March 2011

To the Gilley’s –

This note comes with sincere thanks and appreciation for the Culver’s Gift Certificate and very nice bag with valuable information and goodies. We also appreciate the excellent service you provided in installing our new furnace. Gregg, Kevin and Ronnie were not only very professional, but so personable as well. It is something hard to find these days. We made an excellent choice going with Gilley’s and will definitely refer others that we know to your company. Thank you again for the excellent service and the very nice and thoughtful gift.

With warmest appreciation,

Joe & Sylvia Fuchs – 2009

I wanted to let you know that the workmanship, pricing, and quality work that was performed by Gilley’s was outstanding. The two gentleman you sent were top notch. They did a terrific job. The new plenum, ducting, furnace, and A/C  unit all turned very nice. The job was handled professionally, and I didn’t even hear one swear word, even when your men had to core the 3 holes thru the 18″ thick walls in the pouring drain! I am grateful that I found your company and will highly recommend Gilley’s to anyone looking for Heating or A/C. I would like you to give the two enclosed gift certificates to the Der Rathskeller Restaurant to the two fine men who performed the job, and let them know I appreciated the effort. I am also enclosing ten $5 free admission passes to the Forest City Oktoberfest. If you can make it down to the Oktoberfest I would love to buy you a nice cold one. Thanks again, and best of luck in the future.

About a week or so ago during some of our extremely hot weather, my central air conditioning went on the blink. I made several calls to companies only to hear three to four days or week, even after I explained that there was someone in the house-hold with heart trouble and respiratory problems. I understood that they were very busy, with the temperature what it was. Almost at wits’ end, someone said they could squeeze me in the next day. It was Gilley’s Heating and Air Conditioning. After two trips to my home and several phone calls later, they fixed the problem, but by this time it was after normal working hours, and they kept working until it was fixed. I would really like to thank Ron Gilley and his very thoughtful staff for being there when I needed them.

The Werckles

I would like to thank you so much for helping us at St. James. We hope to see you and your staff at the parish center on April 22, 2009 at 7 p.m.. St. James spring card party will always keep you in our prayers.

Thank you for fixing the thermostat last Sunday. The living room is warmer and the thermostat is accurate too. Before when I would set it, the lower number the needle mark was on wasn’t the same. It is now. It clicks on when it should and is easier to turn. It has been needing adjusting. I’ve been keeping warm in spite of the dampness.

Thank you,

Sandy & Heidi Kuhlmeier

We want to thank you for your prompt and courteous service.


Pam & Chuck Lindgren

You guys are amazing! I am the housekeeper at, the Kishwaukee Community Evangelical Presbyterian Church. When I left the church after cleaning on Monday, April 27, your guys were cutting holes in the restroom’s ceilings fro vents. I cringed thinking of the mess I would find on my next cleaning day Thursday, April 29. Are you sure your Gilley guys did anything? I found no mess. It was awesome! I really appreciate it. Thank you very much.

Dot Gocken, KCEPC Housekeeper

Both of us wish to thank you & American Standard for the generous gift certificate to Lennox. Also, to let you know we’ve been pleased with your service. And to praise all of your service people who have serviced our new furnace.

Many Thanks,

Mr. and Mrs. Roy Clark
