      Have used Great Lakes Heating and Air Conditioning for several years. Just had a Furnace and Air Conditioning installed. Amy, our Comfort Advisor was absolutely excellent. She was very detail-oriented, explained all clearly, and answered all our questions. We couldn't have asked for a better person to work with. Jeff, our Installation Technician did a fantastic job. He was considerate of our home and there was no clean up needed when the job was complete. Another important area to us is when you call in for service. We have always had the phone answered in a professional manner. Thanks so much, Great Lakes!


      I am a customer for "life." My heating and air (18 years old) needed replacement along with a cold air duct installed in the finished basement wall. I am extremely detailed (OCD) about all home improvements. I consulted Great Lakes Heating and AC and received very competitive pricing from (sales representative/Bruce) with excellent communication and follow-up during and after the sale. The two techs (Nathan and Sam) performed all install services in an excellent manner and demonstrated the excellence of the Great Lakes Heating and AC brand. Their attention to all details, careful and detailed explanations of the install processes, time of arrival, clean up after the job (daily), represent the excellence of customer services. I am forever appreciative and grateful for a job well done and will be a dedicated customer for "life." Thank you, thank you, thank you! I urge all, PLEASE use their services for all of your heating and AC will not be disappointed!

      Sergio and Matt were great! They did a good job...professionally and had me up and running again in about an hour. Installed a new thermostat for me and showed me how it worked before they left. I'm very happy!

      Shawn Conery was the Service Technician this time, his first visit to my home. He was VERY thorough and did an excellent job completely checking out the whole system. He did find a bad part, replaced it , put everything back together and fired up the furnace. It worked perfectly. GREAT JOB!!!

      Furnace was out on a Sunday morning. Great Lakes was very responsive and the technician really, really excellent. Tracked down and explained the problem and came up with a cost effective fix for now. Couldn't be happier.

      Our a/c died a few weeks ago with temps in the 90s. Great lakes came out the same day, Mr. Stoner was professional and gregarious. No one likes to have to pay for a new a/c but he made it a bit easier. The price was comparable to other companies in the area. They had my new unit installed within two days. The gentleman who installed it were on time and worked extremely clean. If we were not already impressed with the impeccable service the lovely gift bag and the lemon cookies were out of this world. Great lakes is a gem and we will be calling for all of our future home needs.

      We have always been happy with Great Lakes Heating and Air Conditioning services. Our service tech person Dion Winter always takes great care of us. He arrived with a face mask on and kept a safe distance while getting us ready for the summer months of cooling. If we ever have any problem this company has always responded to our needs.

      Juan was very knowledgeable and professional. He fixed our AC unit and made other suggestions for cleaning and filter changing. We had a very positive experience with him -- felt he was very well-trained and would recommend him and his company in the future!

      I'm very pleased with Great Lakes Heating and Cooling. They're always on time and I'm always satisfied. Their level of professionalism is excellent. Our technician today was Dion who was fast and thorough. I'm going to be a customer for life.

      Top-Notch from start to finish. Installed New Furnace and Air Conditioner plus had the air ducts cleaned. Bruce, Stan, Josh, and the Twins all were very Professional and Courteous. Very smooth process, everything looks amazing. I would recommend them to anyone needing a new system. Thank you.

      The differences? When I needed new AC, I got three on-site estimates. One was a glossy car-salesman-like company, another was an old-family folksy company, and then Great Lakes. The glossy guy I disliked, and it was pricey. The folksy guy I liked, but his knowledge was lacking--he thought my old AC concrete pad would work fine, but the Great Lakes guy said you need a new pad, and also he recommended running a new duct from the basement to upstairs so that cooler air there saves stress on the AC system. I have confidence in this company.

      Everything was done quickly and professionally. Josh is a good representative for your company.

      Very satisfied with Great Lakes service. Happy with our new furnace and comfortable knowing we can count on them whenever needed.

      I have had the furnace and air conditioning for 6 years. I have yet to need anything but preventative maintenance. Once in spring and once in fall. This is as a member of their discount club. They are quick, courteous, & professional. I would recommend them to anyone who needs HVAC maintenance or new equipment.

      Great Lakes Heating is one of the best Heating and Air Conditioning Companies in the Michiana Area. I have been using them for years now and will continue to do so because they do such a great job.

      Our technician was very kind and respectful. He talked us through his thought process and gave us a lot of information. He was open and honest about options.

      Personally, I know he does a good job. Our neighbor is VERY satisfied with him! We even had your sign in our yard.
