Lanz Plumbing & Air

Lanz Plumbing & Air works from Champaign handling HVAC needs across the region. They focus on keeping air conditioning and heating systems in good shape for local homes during the hot summers and cold winters that hit Illinois hard. The outfit runs service calls day and night so people do not have to wait when a furnace quits or an AC unit fails in peak weather. Their background includes plumbing and underground work which gives them extra know how when HVAC lines or related systems need attention alongside the main job.

Lanz handles AC installation and repair jobs where units break down from heavy use in summer heat. They put in new furnaces and fix existing ones that have trouble starting or blowing warm air. Maintenance on heat pumps and boilers keeps everything running smooth without big breakdowns later. Duct cleaning removes buildup that affects air quality and flow through the house. For homes with special needs they set up ductless mini splits or full geothermal systems that save on energy. Tankless water heaters and repiping work sometimes overlap with HVAC projects so the same crew takes care of those too without extra contractors showing up.

Customers keep coming back because the response time stays fast even on busy days and the repairs hold up through the seasons. Quality shows in how systems run better after the visit without constant callbacks. Price comes in fair for the parts and labor involved while communication stays direct so homeowners know the plan from start to finish. Local weather in Champaign brings extreme cold and heat that tests every unit so reliable service makes all the difference when things go wrong. DIRT Score 4.87 from 2977 reviews on Finds.

“We had a 1964 Sunbeam belt driven furnace in our basement. We decided to get an upgrade and add central air conditioning to our house! They did a fantastic job and were there for maybe 5 hours! Ty and the crew were fantastic to work with! Thank you guys! Ps you guys can absolutely use the photos for a before and after advertisement!”

“OK , thanks. I couldn't figure out how to do this. Gerald did a thorough, excellent job finding the leak, taking pictures and capping off the lines. As well as removing the drinking fountain that was the cause of the water leak. We appreciate Lanz great , prompt service. Thanks again Gerald !”

“Wes and his 2 man crew showed up at 7 am on the coldest day of the year (-2). Removed old furnace and central air. Installed new Trane Hybrid (gas furnace/Heat Pump) combination system. By 3:30, they were finished (incredible speed and efficiency). The installation was beautiful…everything was done to perfection. They were very particular in cleaning up after themselves (Wes vacuumed the floors and swept the garage out). They hauled away the old furnace and a/c. Wes spent a good bit of time training us to use the high tech thermostat and the Trane app on my phone. Everything was professionally done…in short I highly recommend Lanz heating and cooling.”

“Well, my heater system went out in December 2025. I needed a heater replaced, it could not be repaired, I was told by Lanz, then I was told the heater cannot be replaced without replacing an air conditioning system as well at the same time. They said don't worry, you're pre-approved and there's no interest for 5 years. I paid $12,600 to have a heater and air conditioning unit replaced, December 2025! I had heat again so I had peace of mind, but I have 2 jobs now. The air conditioning started going on in May, someone came out and checked it in May and said it was great, running great. Here we are, June 30th yesterday. I had thermostat set at 72, I came home 7:30 in the evening from my second job, and it was 78° inside... called lanz, someone came out said he thinks there's a part that was”

“Called and got an estimate took several days to receive it. Told them a date to start after. Didn't hear from you until I sent a email. Thought you should have had better communication. Installers were great but one piece was cracked and they had to come back and didn't know how long it would take to get new piece. Last we paid our bill but Lanz didn't subtract our down payment. I had to call to get it fixed and instead of credit to my card you are going to send a check. I think Lanz needs better communication with the customer. The price was a little high I think but I know with everything going up it is hard. But the installers were very good and clean. They did a great job.”

“Huge thank you to Lanz for the incredible service and such an amazing upgrade to our home! We had a brand-new HVAC system and water heater installed, and the entire experience was outstanding. The team was friendly, professional, and communicated every step of the way. Top-notch customer service from start to finish — I highly recommend Lanz!”

“I thought I had a blocked sump pump, some nasty-looking sludge in the basement and some standing water but not a flood, so no emergency, right? It turned out to be a blocked sewer line that was adding water to the basement every time I took a shower, did the dishes, etc, etc……Shannon came within an hour of my after-hours call to Lanz, and spent two hours in the dark in my mosquito-infested driveway restoring my ability to use water. He was pleasant (“They’ll only itch for a little while”) professional, and patient and clear with his answers to all my questions. I appreciate Shannon in particular and would definitely call Lanz again.”

“Our Lanz experience was the best! Our hot water heater gave out and they were available the next morning to replace it. Kyle and Brennan did an amazing job. Very professional and knowledgeable! I highly recommend them!”

“I had a great experience with LANZ Plumbing Heating/Cooling Services, especially with Wyatt S. — he is truly the “BOSS.” Wyatt is the Lead/Senior Plumbing Technician, and his knowledge and professionalism were outstanding. Before calling LANZ, I contacted 4 different plumbing companies. Most of the technicians barely even looked at the pipe and immediately gave me outrageous quotes close to $2,000 just to repair a small pinhole leak. It honestly felt like they were more interested in selling expensive repairs than actually solving the problem. Wyatt was completely different. Within literally 2 minutes, he diagnosed the issue, explained everything clearly, and already had a practical solution ready. The best part was the cost — it was almost 10 times cheaper than what the other companies ”

“Lanz team, I wanted to thank you for your prompt response and especially for sending us Sam, who literally saved us. Sam quickly arrived, was very friendly, understanding, professional, and incredibly knowledgeable. Sam explained everything very clearly, worked efficiently, and left the area clean when he was done. In a stressful situation, it was a huge relief to have someone so reliable and courteous. I cannot recommend Sam highly enough, TOP- NOTCH Service!”
