Our air conditioner was failing to cool the house after a few consecutive hot days and they sent a tech out several hours after we called, same day. Our tech Mike O showed up on time, was friendly and knowledgeable, worked efficiently, helped us repair the unit (bad capacitor) instead of replacing it entirely, despite it being a very old unit. I would highly suggest this company to anyone needing service, they also came out and serviced our furnace last winter. Their costs seem to be slightly lower than other companies in the area. Initial diagnostic fee was 125 compared to 160+ for all the other companies I called. read more

Service young man very professional and respected house, wore booties inside, explained what he did, recommended equipment which I did want. Did paperwork and needed signature. Getting a service plan I highly recommend. When time for a service call - the office will give you an email or text/call. read more

We first used LCM when we needed both new furnace & A.C. The owner Shawn set an appointment & came to review our house to help sort out options. He was thorough and covered both lower cost equipment on up the catalog. When I narrowed the field he gave me his expert opinion on the best approach. Installation was efficient and professional making sure we knew all operating details including a smart thermostat. We got several rebates all identified by Shawn. Great service ! read more

I've never rated anything or anyone online before but today it has all changed. Today turned on AC and just felt a small cool air coming out of the vents. I gave LCM a call at 705am they send of Shaun Kelly. He found the problem in minutes and went to work. Not only did he fix the problem he worked on the thermostat attached to the wall and saw a problem and fixed it. Oh and by the way my late husband passed away many years ago and he remembered I was going through hard time and asked how I was doing. I instantly got emotional and gave him a hug. Shaun Kelly thank you for being a Kind and caring person looking out for his customers. read more

* There are no words enough to express our gratitude to Shaun, Owner of Lake County Mechanical Heating, AC, Ventilation (847) 989-4649. HE WAS NOT CONCERNED ABOUT THE MONEY. HE HELPED US FIRST AND NOT WORRIED IF THEY GOT UNDERPAID OR NOT PAID AT ALL. IT'S SO UNBELIEVABLE THAT THERE IS STILL SOMEONE LIKE SHAUN TODAY. He helped us twice now with our issues of our 29 years old furnace and AC. We cannot afford to replace it so we just depend on honest help. Our furnace broke down on Sunday, 5 days before Thanksgiving. I checked it myself and this time looks like the valve regulator is bad. I became worried coz replacing this is very costly. We tried to get help from our friends but unable to help us. It's getting cold inside the house. Our kids wore sweater and covered with their comforter while watching TV or doing their school works. Fortunately we have this small space heater and temp outside were 19-25. I was so desperate, so I called Shaun again. I was a bit a shame coz he already helped us last summer and here I am again with a new issue... a heater this time. But Shaun was such an amazing person. He's so compassionate and concerned. He tried to diagnose my issue over the phone directing me what to do. Maybe their service is not actually needed so I won't spend unnecessarily. When I told him it's been down for 3 days now, he became so concerned and worried and said "We'll fix that, we'll fix that and we will not let you go on without a heat". I thanked him, but in my mind I begun to worry coz I knew that replacing a regulator cost thousands of dollars. Shaun made a plan to replace the valve right away while I apply for financing of a new furnace. I just need to make a "drop in a bucket" deposit. I went ahead and apply for financing but was denied. I let Shaun know and told me not to worry. "We'll fix that, we'll fix that. I will not let you celebrate Thanksgiving without a heat" oh thanks I said, but again I'm so worried of costly repair. I only have $250 available which I borrowed from a friend. I informed Shaun that I only have $250, still Shaun told me not to worry. Phil, one of the technicians of LCM, arrived. He's very polite and respectful. He checked the furnace and found that the valve regulator is bad and needs to be replaced. I want to collapse coz I was just hoping some kind of loose connection only. Phil called Shaun and got an instruction to go ahead, replace the regulator. As Phil started to work on my furnace, I was so worried how can I pay them, I only have a borrowed $250 and that's it. My furnace is located in a very small closet with a water heater infront. There was not enough room for Phil to work. He has to position his body sideways. Very difficult job but Phil stayed cool and polite while he explains to me about what he's doing. Amazing guy!!! Finally! After more than an hour of laborious work...Phil asked me to turn on the heat and wah lah!!! My broken furnace came back to life again. Phil is exceptional-he did it right the first try. I was so happy but I started to get very worried. Phil went out and came back with a receipt. He started to fill up information, my name, address etc. As Phil writing was those info, my heart was pounding fast. I was preparing what to say the moment Phil write on the space a big $ amount. But I could not believe my eyes when Phil wrote $0, zero on the spaces. I can't say a word. I must be dreaming. This can't be true. This guy had laboriously replaced my regulator and he's charging me nothing? Phil told me that Shaun wanted to help us. I was so speechless. All I can say was thank you as I held back my tears. I respectfully offered Phil a gift as a gesture of my huge and sincere appreciations but he politely turned it down and told me that they wanted to help us. I told my wife what happened and we both thanked the Lord for these amazing people that He sent us. I called Shaun in his office and expressed our appreciation. What Shaun didn't know was that, we can now use some of the $250 to buy food for our Thanksgiving celebration. That day we went to the grocery with praises in our hearts. I am writing this letter to share to everyone what Shaun has done for us. We will never forget this for the rest of our lives. If you need honest guys to fix or replace your furnace and AC, PLEASE consider doing business with Shaun. They are not only excellent in this trade but very honest and with a huge philanthropic heart. If you are capable, I encourage you to pay extra than what they quoted you as these guys are helping less fortunates. Please let your family and friends read my testimony so they would consider doing business with Shaun. Again, thanks to Shaun and Phil for allowing us celebrate Thanksgiving with warm home and warm foods on the table. God bless you Shaun and may God prosper your business. read more

Absolutely a wonderful company to work with. Their prices are reasonable, they call to verify the appointment on the day and arrival is always near to the stated time. The employees are very knowledgable and do good work. Can't say enough about them for both furnace and AC installation and service. read more

We needed a new boiler at our summer cottage. The house never seemed to warm up in the winter and the second floor always got so hot you couldn't stay up there. Shaun from Lake County Mechanical came out and gave us a quote and suggested we put the two floors on separate thermostats and use a Ecobee thermostat on the first floor. He put it all in and the whole system works great! I've called him with questions and he's always there there with an answer. What I also like about the company is it's not so big that you don't know who's going to show up to work at your house. read more

Definitely recommend LCM. Air went out during heat wave, called LCM on Friday truly not expecting that anyone would be able to come out that day. To my surprise Benjamin showed later in the day, gave me my options, Benjamin explained that my unit would last this summer, but it is on borrowed time, which I knew, he got unit temporarily running. I decided to replace unit, (did not want to be in the same situation again). Never at any time did we feel as if they were trying to sell anything we did not need. Sean& Trace installed it the new u it. Sean checked my furnace over, cleaned it and made sure everything looked secure and everything was as it should be. Their Techs are very professional, knowledgeable, courteous, and cleaned up after each visit. They also do a check up on unit two weeks after installation to ensure everything is working as it should be and to answer homeowners questions concerning unit or operations of unit They also replaced a furnace at my daughters home, plus did repair work at my other daughters Home on her air unit. They have definitely won us over from the owner, office staff and their techs. read more

I highly recommend Lake County Mechanical and their technician Jason. On-time, very professional and great service. I would definitely use them again. read more

We have used Lake County Mechanical for years. My father lived alone & had a hard time communicating due to a stroke. Everyone at the company is trustworthy; if I wasn't present, I trusted them to write the check since my dad had difficulty writing. Our technician, Jason, very personable. He recalled a story from last years' maintenance visit about an interesting conversation he had with my dad which was very touching since my dad has since passed. Whatever work he suggested needed being done, I agreed to since this company is not just out for your money. The company cares for its customers - very refreshing since it seems most companies just care for how much they can bill you for work whether or not you need it. read more

Called this Company after contacting a few different ones. They gave me a reasonable quote so I decided to go with them. The air duct cleaning was outsourced to a company in Chicago, which I was not told. The air purifier system that was installed was not working; So I called the gentleman that came out to install it although his cell phone went directly to a number no longer in service. After being on the phone with the call center and talking to three different people they got a hold of the on-call technician. He called me after about ten minutes and I informed him of the problem and explained that I just spent a lot of money on something that doesn't work. He asked me if it was something that needed to be fixed today. I explained to him that it was, unless they wanted to discount the price quoted to me. His response was OK I'll just come out. I enjoy and want to buy local but unfortunately this experience wasn't great. read more
