I am very pleased but not surprised by the great service.. He as on time and solved my problem quickly. I called on Monday morning and @ 8;00 on Tuesday morning he was here.. I hope I won't need him again but I would not call any other.

Great service and great attitude!

Rocco arrived a few minutes early and was very friendly, courteous and professional. He inspected both our AC and furnace and gave honest recommendations about maintenance options.

Rocco was great. He diagnosed my problem quickly and fixed it even faster. I chose your company because you are a member of the Northern Kane County Chamber of Commerce. I highly recommend you to anyone that needs help with their heating and cooling.

Great service and fast. Got the air conditioner up and running on a very hot day. Rocco had to work in an extremely hot attic but he got the job done quickly and efficiently.

I have a small business with two locations. On personal recommendation from one of my employees, I called Leith Heating when our second location, in Barrington, had a heating problem. It wasn't an emergency so Brian scheduled his visit at my convenience. He arrived early and his first step was to LISTEN to my explanation of the symptoms, which is great! I have a background in heating and electrical work and his knowledge of heating, cooling, and diagnosis is impressive. Very organized, clean, and efficient. As the business owner, he gave me a short list of maintenance items to perform, both to save money on the trip and to help head off problems in the future. During his visit he even found and corrected a problem that we weren't even aware of yet!

All-in-all I was very impressed with my first contact with Leith and will happily use them again in the future and would highly recommend Leith to others!

Came in for a cleaning with one of your new girls, didn't catch her name but she has blonde hair and is new to the practice. She was very good and attentive to me. Highly recommend her. The only downside was my 30 minute wait to get in to be treated.
