Mike was more than prompt to come to my house, give me the best estimate, and educate me on the process. He was available next day to install. He and his assistant were on time, done faster than estimated, cleaned up, and confirmed my satisfaction. I will skip calling my regular go to and go with him in the future. Great value and great service. I'd strongly recommend calling him.

Stay away from these guys or at the very least get multiple quotes. I called trying to get an…read moreestimate to replace a boiler when it suddenly died and we had no hot water (and a small child). Talked to Jim and he was nice at first until he was supposed to come for the quote and something I said made him thinking I was getting the job quotted by more than one person. I wasn't getting multiple quotes, in fact I was having a hard time finding anyone who actually dealt with boilers. He specifically said he wasn't interested in coming to give a quote if others were involved and when I tried to tell there weren't any others he basically hung up on me. Called him back immediately 2x and left messages with 0 response. Completely unprofessional. If I was actually bidding the job out (which I wasn't) only someone with something to hide would be that concerned so be wary of any quote you get from these guys. Crazy shady and frankly glad we found someone else ‐‐------------------ Jim, in response to your reply you should check your messages again. Here's the text message I sent you after you hung up on me and after I called you back to try to explain and you refused to answer. Its clearly sent to the number you listed...

He replied around midnight & was willing to explain what needs to be done & the price range. Jim came to fix our pipes the next day, although it was late at night since he got stuck with another project. Jim was very friendly, caring and dedicated to having the job done right. We're so glad that we found Leipart heating & cooling. Will definitely use his company again for any heating & cooling needs.

I needed a humidifier installed in new construction home. I'm extremely pleased with my experience…read more They explained things patiently and thoroughly. When they came for the install, they informed me that the original humidifier was not the best fit. Rather than installing it just to get the job done they paused. They recommended a different option that was actually a lower cost and that they would have to come a different time to install it. This shows their dedication to customer satisfaction and making sure the customer has the best product to address their needs. Highly recommend them.

I called Lockwood Furnace Company and always so polite and helpful is Tricia the scheduler…read moreI cannot say enough about Matt service technician, Bob service manager, Andy installer, and Terrance assistant installer.These four gentlemen did a project at my home just recently. Each one of these gentlemen treated me and my wife with the utmost respect. All four gentlemen where so polite, caring, and professional with a sense of humor.Each one explained the job that they where doing with simplicity so one would understand. These men where all so honest and could have taken me for thousands. But being so honest it only cost me $1300.00. Plus they covered my steps and the room going to where the furnace was. Thus cleaning up the mess. I've been to other companies but Lockwood Furnace Company at 2300 McDonough St, Joliet, IL 60436, (815) 744-4004 has my business from now on. Plus Lockwood Furnace Company is quite affordable. I will tell you do not look any further because Lockwood Furnace Company will not let you down. I firmly believe that if you give Lockwood Furnace Company a try. This company is a keeper for me and can be for you.
