Northern Continental Heating & Cooling, Inc. 740 McArdle Drive, Crystal Lake, IL 60014

"2024 - Technician Matt was outstanding and a great guy. I so like they actually check many components on the furnace to ensure they fall within manufacturers specs. Northern Continental does not disappoint. Thanks Matt! 2023 - Technician Abe was extremely pleasant and explained what he was doing. Fortunately all is well with our two furnaces. Thank you Abe!"

"Dan and his team were the best. They were prompt with their responses and punctual to all of the appointments we made with them. They installed a new tankless water heater in my house and they did an excellent job. They work was extremely professional and they left the house like they were never there. I can't say enough about Northern Continental and would recommend them to anyone. Thanks again Dan and your team, you guys rock."

"The degree of professionalism was actually amazing. I was in HVAC for several years and I can tell you that these people are honest.. they were very professional when installing the air conditioning system neat and clean.. The pad for the air conditioner was installed level... I can't remember the salesman's name but he was extremely easy to deal with. I'm 74 years old and he treated me with a great deal of respect not looking down at me because of my age and the fact that I'm a woman. If you're a woman reading this you understand what I'm talking about. I've recommended them for repairs and everyone has come back to me and said they'll never use anyone else. If anyone would like to see the work that they did please contact Continental you have my permission. UPDATE 11/4/22.. My April air whole house humidifier was not working. I called them because of the work that was done previously. The owner came his name was Dave. He removed a panel that my previous company never removed. He found a wire that was off and apparently that had been off since installation which is it's about 3 years ago. For some reason the water to the April had been turned off and it wouldn't have been me because I couldn't have reached it and I would have had no reason. He knew exactly what was wrong. He was here probably 20 minutes and checked everything. I've recommended him to several people and everyone is always come back and lauded me for recommending them. There are three other companies that would not recommend. I've lived in this home for almost 30 years so I've had two heating systems installed three air conditioners and I would never go to anyone else except for Northern."

"I’ve been using northern continental for about 7 years. Dan, Dave and the entire team are fantastic. They are honest, professional, and have provided great services for our family. We have had our heating and ac installed and maintained by them and they are the best around. Today at around 3pm our boiler that was about 40 years old failed, during the coldest time. I contacted their office and Dave was able to come out after all his other calls. He had the parts needed and had the heater fixed before he left. Can’t say enough about these guys"

"Professional installation and clean up. Dan our salesman was vary helpful going above and beyond for us. The crew was on time. We are vary satisfied and will use them in the future."
