Lanz Plumbing, Heating and Air Condition Services is the best all around service in Champaign. They are on time. Wear sleeves on their shoes to protect your home, they thoroughly check out your equipment and answer any questions or concerns you may have. I feel they honestly give me good advice about the work they are performing.Good people 👍Thank you

Great customer service! We recently put in a new HVAC unit. Michael helped us make the best decision for our household and budget. We were surprised by the difference the new one made. In the past, the temperature was set at 69 degrees, but with the new unit, we can keep it at 72 or higher, and it feels cooler than before, as it is now pulling humidity from the home. Everyone on their team has been easy to work with, excellent in follow-up, and respectful while in our home. We haven't received a power bill since installing the unit, but I anticipate it will go down. Highly recommend Lanz!

The service overall was good. Technician Jesse was professional and did the job well.The communication could be worked on a bit from the company.Our appointment was for 1pm. At 1:10pm I called the office and spoke with Steve, if I’m not mistaken. I introduced myself and asked Steve if we still had an appointment for 1pm. He said yes. He said the tech was running behind and should arrive “sometime” this afternoon. I asked for a round about time, and he said around 2 or after. I said, in a calm tone, our appointment was for 1pm, we planned for 1pm and now we have to wait. I asked Steve if they could implement a plan to call customers if they will be late. Now, I could tell this rubbed Steve the wrong way. He wasn’t blatantly irritated, but I could tell he was irritated, because his tone changed just a bit. He wasn’t rude, but I could tell. He said, the tech just finished up and should be heading your way in about 15 or 20 minutes. I said great! I then said, in a calm tone, I am an easy guy to get along with, and communication is key with me. I said, I don’t care if you will be late, just call and let me know. He said ok. I started to say have a good day and he hung up.I know this a long review, but I believe in giving my full review for a business, whether it’s good or bad.I did appreciate Jesse and he did a good job.

Josh has been at our home twice to do an emergency repair and to perform maintenance our on AC units. Both times I was impressed with his knowledge and his ability to explain the issues to someone lacking in the knowledge of how AC units work. He took the time to show me where the filters are located so that I can change them on each unit. Thanks Josh! I appreciate your level of service.

tldr: the employees are friendly (hence the 2 stars not 1), the prices are a crime, the scheduling is a joke, the service is mediocre. On multiple occasions Lanz came to fix a problem, failed to fix it properly, and then had to come back and fix it again.First time: blocked drain. Guy 1, "unclogs" it and leaves, charging me 200. Did not fix the symptom OR the cause. Guy 2, finds the cause (poorly arranged pipes in the basement), fixes the symptom and not the cause. Guy 3, starts fixing the cause (quotes a price)... realizes he planned his solution poorly. Quotes me a new price that is double the previous. He's already started repairs so what am I to do??? Lanz DID give me a credit for the first dispatch, but the overall price was still over 1000$ for a few hours of work rerouting pipes.Second time: new toilet install. Leaking a year later, no discount, no accountability. I felt like I bought a used car from Matilda's father, it ran JUST long enough to survive the warranty.There were also two other occasions with no particular issues with the service, except for the price which came out to around $400/hour!!

My parents had Lanz out for a clogged drain, and an unknown leak with their bathroom plumbing. Lanz was quick, extremely professional, considerate and even pointed them in the right direction for recommended repairs. This is the new family “go-to” company for HVAC, plumbing and underground solutions.

We were interested in a second opinion on a heating/ac system, and Lanz was willing to come out within a day to provide the second opinion. My sister, who needed the second opinion, has memory problems. She forgot that the tech was coming and at the first visit was out walking her dog and not home. The tech was very kind, and came back later in the day to provide the service call. He serviced the system for a very reasonable price in comparison to the other company, and we are now solid Lanz customers.

A hard working team- with attention to detail and completion in 24 hours.Thank you so much,Velma OlsonLacinda CarringtonDebra Olson

Our salesman, Michael, was friendly, professional, thorough, and responsive. I asked many questions and always felt my time and satisfaction were valued. When Michael didn’t know the answer, he found someone who did. Proposals were provided promptly and even revised for me several times on request. Lanz is not the cheapest Vendor out there, but I have literally nothing bad to say about my entire encounter from the first phone call to the completion of the installation. They even have checked in several times in the following weeks to make sure the equipment was operating to my satisfaction. We also had plumbing work done and I am highly satisfied. Once again, not the least expensive but I feel great peace of mind with the work that has been done in my home. A great company with an exceptional team!Will the Technician came to help after we accidentally hit a wire on the AC unit while trimming grass. He was courteous, professional, and thoroughly considerate and helpful in the repair!

I was told my furnace and air conditioner needed to be replaced and that the cost would be $20,000.I contacted Lanz Plumbing, Heating & Cooling for a second opinion. Turns out both the furnace and the air conditioner are working normally; no repairs were needed.Thank you for your prompt response and your honest assessment of the need.

Tom, Austin, and Shannon did an excellent job in getting my plumbing issue fixed, and I'm grateful for how prompt and professional they were. They got the job done in a timely manner, even though it wasn't an easy job. Truly they went above and beyond, and I would not hesitate to call Lanz again for any plumbing issue I might have in the future! Thank you again!

From the initial consultation and walk-through with Kurt, to the final handshakes with Jamie and Austin, this company has exceeded all expectations. Wealth of knowledge and experience, ability to set goals and meet them, and willingness to do what it takes to get the job done well are hallmarks of a quality company. And these people have them in spades. Our home is a tri-level that has only ever had baseboard heat so everything had to be installed from scratch. No easy task, but Kurt bid it well for the right equipment at a fair price, and Jaime and Austin made it happen...On 3 different levels, for 3 solid days , in 95+ heat...The entire system looks and functions like pros did it..'cause they did. Are we satisfied? ..Yes for sure.. Would we recommend Lanz? . Yes..and they can put a sign in our yard anytime.. There's a reason this company is continually growing..quality work will always be in high demand. Thanks to all( Melissa and Kinsey in the office as well) for a job well done.

I had a water leak under my home-on a slab. I had called a company I had been a customer for years and they would have been able to do it as planned. Unfortunately the way things went it was one obstacle after another and was going to be a huge mess.Not the fault of the first company, just one thing after another unexpected thing making a relatively simple job a real headache.I called Lanz and they eased my mind considerably just telling me what they could do. They had the needed equipment to bore under the foundation and run a new water line without tearing up far more of my yard. They did a great job, cleaned up better than expected and at a reasonable cost.I am quiet pleased with their work and do recommend them.

Karen James

22:36 08 Apr 25

2 other companies wanted me to spend thousands for an outside cleanout for my mainline. They said without it they couldn't remove the tree roots. The men from Lanz were very professional and cleaned the entire line easily. You get what you pay for.
