Review from Barrington customers:

“We needed a new Furnace and A/C. I found Leith Heating & Cooling on Angie’s list and was impressed with the reviews. Brian Leith provides the highest level of service, from education on systems and options to ensuring that you are getting the correct system for your needs. We needed a creative design to incorporate a High Efficiency furnace in a finished basement, Brian came out twice to look at options and we were able to come up with a design that worked. Brian’s communication and timeliness are excellent. We are very happy with the installation. I highly recommend Leith Heating and Cooling for your HVAC needs.” -A, Barrington

“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!” – Anderson’s Candy Shop, Barrington, IL

“I have been doing business with Brian for years. Brian is a true professional, Very knowledgeable and explains every step of what he has done to service our systems as well as giving us a look forward on what type of issues to expect and prepare for based on system age etc. Once we returned home from a trip late on a Sunday evening in the winter to find our furnace had stopped working while we were away. Brian was able to talk me thru the problem over the phone and fix the system…..on a Sunday evening!”- Andrew M., Barrington Hills, IL

“Leith has taking care of our furnaces for years now and we couldn’t be happier! They do great work at fair prices and we will continue to use them in the future.” – Brian, Barrington Hills, IL
