The HVAC Trane Consultant, Michael Savage, took a great deal of time to examine our current HVAC system and then explain the benefits of a new Trane HVAC system. The Trane installation team headed by Chris Sussen, was very professional and explained what they were installing and how the various components worked together. They were very neat and wore masks the entire time they were in our home. They explained and demonstrated how the thermostat controlled the HVAC system.

Everything was explained to me, and all my questions were answered. He was very pleasant. The problem was taken care of in less than an hour. Very pleased with everything.

I called them at 10pm on July 2 because my AC stopped cooling. The technician called me and explained that he couldn’t get here that night but would be here the next morning around 9am as I would be the second client. I called the office in the morning and they explained it would probably be a little bit later in the morning. So the repair person arrived at my house around 11:30 AM. He diagnosed the problem and had everything working for me by 1:00PM. I am very pleased!

I first filled out the service request form on the website and was never contacted, so I had to call. Someone was sent very promptly and he was nice and helpful. We were not given a quote at the beginning, so we were quite surprised by the high bill but some things were sorted out to help since a quote wasn’t given beforehand. Overall, a bit higher priced but very quick to arrive, friendly, and the quality of the repair was great.

Our tech was great. He definitely knew what he was doing. Courteous, respectful, and communicated what he saw and what he was doing. Very impressed with him. So much so that we decided to sign up for the service plan and also scheduled another service to replace our two bathroom and kitchen sinks this Friday.

I asked someone for recommendations on Heating & Cooling Company and she immediately recommended me to try LANZ. I called them and Rich answered my phone and without asking a lot of questions or FBI- ing me, or asking ridiculous questions, he immediately dispatched the Joey who is well knowledgeable about what he was doing, The diagnosis came out that I needed a new water heater which I also was aware of the old age of my Water Heater because I have tried several repairs on it, and other companies were too exaggerated about the prices and all the dispatcher flat fees, very high for no big deal.The next day Joey and Kyle were ready with my new water heater and the insulation just took less than 2 hours. The two technicians Joey and Kyle are very knowledgeable, respectful, strong, clean, focused and above all, they educated me about the goodness of being LANZ customer and the free services which comes with it. My water heater was approved by the Inspector of Champaign Division and everything was well assembled. Within 24 hours, I had my Hot water back and enjoying every bit of it. Thank you so much for the great customer care service you showed.They (LANZ Company) made a follow up phone call to make sure everything is well and asking me the size of my Air filters so that they can drop them off. Am very happy!I 100% recommend this company. You will see it yourself.

My drainage was slowly getting worse and worse. My grandson flushed the toilet. Not only did it not go down, but started backing up into my tub! YUCK! I needed help asap! So I immediately called (Thursday evening after hours), and left a message. They called at 8a Friday to set up a time for them to come diagnose and fix it. They were here within an hour!! Come to find out there was and had been a deceased possum in my main line. They get an extra star for dealing with the horrible stench!! It was quite the job clearing it all out! At first 1 gentleman, and then a second came. The entire time I felt like this job was a priority to them. They communicated throughout…even with my autistic/adhd 9 year old grandson. Both men were extremely polite and informative. Exceptional customer service!!! Plus cleaned up the best they could, and gave me suggestions on how I should clean up what they couldn’t. Also replaced the 2 caps that were missing that’s allowed the possum to get in. The cost was fair and comparable. Best part…supporting a local small business. I highly recommend them. Absolutely phenomenal service in every way!

KJ Gray

23:20 20 Mar 26

I thought my sewer line running to the city sewer was completely compromised and I was in a very peculiar situation. I had to work and my girlfriend was home. I just bought the home and I was thinking the worst. Shannon and Dedrick came out and camera inspected and could only get so far. There were many tree roots in the way and I had a company come out and try to clear them. Lanz had the right tools for the job and recommended I have them cable the line. I agreed to the estimate, and after cabling and inspecting they informed me that the line was completely clear. I only had one spot of the sewer that was compromised. My girlfriend told me they worked like a well oiled machine and had their methods down. It was decently pricey but they were extremely thorough. What I thought would end up being thousands was only hundreds, yet it was worth every penny. Wish I started with Lanz. I'd recommend these guys to anyone. Thank you guys again for my peace of mind!

Barbara Burch

20:24 20 Mar 26

21:35 13 Mar 26

We had a leak inside of our water heater, and an employee from Lanz was promptly scheduled to come check it out. He was very thorough, and let us know it would be best to just replace the whole unit. Less than a week later they came and did the replacement. We then had some issues with water pressure and reached out to see if that could possibly be the result of our water being shut off. They sent someone out and got everything sorted for us. This technician, I believed named Sam, went above and beyond for us. Absolutely recommend Lanz and their services.

Had two other plumbers out to look at a sewer line backup and was told the line was broken and would need dug up and replaced. Lanz was able to cut out the roots blocking it and confirm the line was actually in good condition which saved me a ton of time and money. First time using them but I would strongly recommend, they were very professional and did a great job.
