AC, Furnace & Plumbing Experts in Mahomet, IL

We experienced a serious sewer backup on Christmas Eve, with a house full of people, and Lanz, Inc. came to our rescue. Their team was on-site for over three hours, working diligently until the problem was fully resolved. At no point did we feel rushed or dismissed—only reassured.I want to give special recognition to Holden Yates, who truly went above and beyond. Coming out on Christmas Eve meant a real personal sacrifice, and his professionalism, calm demeanor, and determination made an incredibly stressful situation manageable. He explained what was happening, stayed focused on the solution, and didn’t leave until the job was done right.It’s rare to find this level of commitment and service, especially during a holiday. We are extremely grateful and would not hesitate to recommend Lanz, Inc. to anyone in need of reliable, dedicated service—especially when it matters most.Thanks, again Lanz, Inc. and team!

This was our annual HVAC inspection as well as the plumbing inspection. Chase was friendly and did a nice job with the HVAC. The plumber never introduced himself, never called in advance and had zero personality. He did the inspection but did not send a follow-up report. It seems that everything turned out fine though.

Last winter, they installed an ERV and a heat pump water heater. This winter Wes replaced my ancient gas furnace and A/C unit with a combination heat pump system with some rudimentary zone control. For the first time our top floor is neither too hot nor too cold. Great work. One step at a time, Lanz is turning our fixer-upper into a comfortable home.

Will was here as scheduled. A coworker was also here to check the plumbing. I would like to say that Will was awesome. I've had problems with the filters causing a vibrating noise. I could fix it by buying a much cheaper filter. Will actually took the time and found out what was causing the vibration and fixed it!!! He didn't have to because it had nothing to do with filters or the heating unit. He fixed it!!! Now I am able to use the good filters you all provide and no annoying humming sound. He is outstanding.

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.

Called with Heating down headed into a very cold weekend and they were SWAMPED. Said it would probably be the next morning before they could get someone out. It was looking to be a cold night. An hour later they called back saying they had a technician on their way! We were up and going shortly after. Thanks for squeezing me in! (Also did a great job with testing and diagnostics, and quick on the repair, very thorough)

Labor to find a faulty part that is under warranty. Will pay another $175 to have new/replacement part installed. The outside mini-split unit froze up badly. The circuit board burnt from short circuiting.

Kurt came to look at our bedroom heating issue last week. After talking through all the options (upsizing ducts, mini split, etc) he looked at the furnace, found a tiny, very high, out of reach louvre handle to the upstairs main. It was almost closed! Got it flipped open and our bedroom has been a good 5+ degrees warmer consistently!Appreciate him being honest and seeing if this would work. He chose to show me, and didnt down play the louvre or try to up sell us.His genuine care and trying the simplest thing first will have us coming back to Lanz for our future needs and big future replacements!

Service call for hvac, less than one hour. Price was high and he said it was for 1.5 hrs. When questioned, he said 30 min was for travel time. This is on top of what they charge for “service call” of $85. When asked if this wasn’t for travel fees, apparently it is not. I called the office who promised a call back which never happened. Very high fees for just tinkering with blower motor and adjusting some vents.

Kathy Savitch

23:26 09 Dec 25

I would highly recommend Lanz. Kurtis thoroughly explained the different systems available to me for purchase. He was knowledgeable and patient with my questions.
