Lanz Heating & Cooling, Inc.

Lanz Heating & Cooling, Inc. works out of Champaign as a straight HVAC outfit that handles heating and cooling for houses in the area. They focus on air conditioners, furnaces, heat pumps, and boilers along with ductless mini-split systems and geothermal setups. The crew answers calls any hour because systems do not wait for regular business hours, especially when Champaign weather swings hard from cold snaps to summer heat. Homeowners reach them for new installs or quick fixes when the old unit quits during peak seasons.

They handle AC installation and repair along with furnace maintenance and boiler work that keeps heat steady through winter. Jobs often include duct cleaning to improve airflow, indoor air quality upgrades like zoning controls, and heat pump replacements that cut down on energy use. The same team steps in for mini-split additions in rooms that never stayed comfortable before and geothermal loops when homeowners want a different approach. All of it stays tied to the HVAC side even when plumbing tasks like water heater swaps come up on the same property.

Homeowners note the crews show up on time, finish the work without extra trips back, and keep costs in line with what the job actually requires. Repairs last instead of needing repeat visits, and updates on progress come without long waits on hold. That record of reliable speed and solid results builds the kind of trust that shows in repeat calls from the same neighborhoods. 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!”
