Great service. The AC technician quickly identified the issue, got me quotes on both repair and replacement, and talked me through the options.

I was impressed with the two Lanz technicians who serviced the AC unit and boiler. Both possessed a strong work ethic and a positive, can-do attitude.

Boston replaced my dripping bathtub/shower valve, which took four hours and involved cutting new access panels, cutting and fitting new pipe, going in and out of the crawl space. He did meticulous work and was very efficient, explained everything; bathroom vastly improved. I highly recommend him and lanz. Beautiful job!

AC system went down in the middle of a heat wave. After multiple refrigerant leaks and years of issues, I decided to get a full furnace/AC replacement. Lanz was quick to come out, assess the system, and provide a quote. Despite being swamped due to the heat wave, Lanz's comfort consultant, Kurt, spent as much time as needed to take measurements, listen to concerns, and provide all of the options. After getting two other quotes, Lanz fell about in the middle for cost, but their thorough explanation of options and responsiveness to questions and concerns put them over the edge. Just as an example, after discussing with me how my old system was working, Lanz actually took the time to properly size the system, while competitors tried to upsize the AC system despite issues with short cycling in the past. All work was completed in a morning for a full furnace/AC replacement, and the team was professional. The new system has been working great, and I'm happy I ended up choosing Lanz.

This service was timely and reasonable. The service person was very polite and efficient, having the part that needed replacing on our AC already without having to go searching for it; was prepared for what might need fixing on our appliance. He explained what had been done, and sent a written explanation along with an itemized receipt for future reference, which is much appreciated.

I talked to Shannon about having my toilet back up looked at. It was a Friday early morning and with in an hour he had someone out. They took care of my inside back up and checked the outside sewer. They found an issue that could have turned excessively costly had it not been found. I am beyond thrilled with the quick and efficient service. Now they will be out to repair the sewer line for the house!! Thank you Lanz

Lanz comes every 6mo to perform maintenance on our HVAC system that was installed in June of 2022 based on the service plan we purchased. They contact us to schedule the appointments. They are flexible to accommodate our schedule. They communicate clearly. And provide friendly service while the work is done. They make sure all our questions and concerns are answered before they leave. We are very satisfied with the HVAC system and their service to date.

Brian

19:40 05 Aug 25

Be cautious when dealing with this company. We were surprised by multiple expensive fees that were not disclosed upfront when we scheduled our appointment. Transparency is important, and unfortunately, that was lacking in our experience.

18:40 04 Aug 25

The people at Lanz had previously been very helpful and competent. However, we have a leak in a pipe with hot water, and we are without water and heat for the past four days, and they have promised and promised without delivering. We wait and wait for the promised service and they never respond. The temperature in the house is in the low 50s and we are miserable.

This was my first experience with Lanz Plumbing, Heating & Cooling. They were at my house in less than an hour after my call to see why my A/C wasn't working on one of our 90 degree days. They found the problem and were able to fix while here. The cost was very reasonable. I will highly recommend Lanz!!

7/28/25We had Lanz install a new heating and air system in our home. Everyone was punctual and professional and prepared! The installation crew (Kevin, Cody, and Ethan) took the time and effort to protect our carpet with floor covering as well as the rest of our property. After the installation the only evidence that they were even there was a new furnace and air conditioner that works perfectly. We have used Lanz for all services that they offer including Plumbing, Underground Solutions and Drain Cleaning. We will continue to use their services and make referrals.5/20/24Thank you, Matt! We appreciate your diligence in tracking down a wire that was crushed during a recent remodel and preventing our air conditioning from working. You are an asset to your trade and Lanz!

I called Lanz at the suggestion of a friend, Sue Gass, who recommended them. The gentleman who came to deal with my issue (leaky toilet, identifying whole house water shut off) was named Boston Williams. What a great guy! He was extremely thorough, knowledgeable, friendly and efficient. He gave us multiple opportunities to ask queations and gave us great information. I try to support local since I live in Coles County, but my recent service from locals was less than satisfactory. I am so relieved to know that Lanz will be my go-to for all my plumbing, heating and cooling needs. I highly recommend Lanz!My most recent experience was with two great young men, Will and Josh. Will did maintenance on my furnace and heat pump and Josh checked my hot water heater. All great guys. Showed up on time, were very pleasant and knowledgeable. I highly recommend Lanz.

It was a pleasure working with Boston today! He was very personable and communicated with us on the work he would do. At the end of the job, he explained what he did and our benefits and improvements…like the faucet was now protected from freezing up in the winter. He told us the other services Lanz provides, and they are available 24 hrs. We are appreciative of Lanz’s customer service and quick reply to our needs! In the future, Lanz will be first on our call list, in our time of need. Thanks to Boston and the Lanz Company!!0

We’re really happy so far with our new system from Lanz! The touchscreen thermostat is a huge upgrade from our old Nest—it’s much more user-friendly. The house is staying comfortable, even on 90+ degree days, which is a noticeable improvement from our previous setup.We had a small hiccup during payment when I initially tried to use an expired card, but it was quickly resolved. The new card had already arrived—I had just overlooked it. Lanz was professional and understanding throughout, and we really appreciate the great service.Overall, the experience was smooth, professional, and genuinely impressive—we’re so glad we chose Lanz!

I am very satisfied with the service provided by Lanz Plumbing. From the very beginning, their dispatcher and customer service team were kind, courteous, and eager to help. They answered all of my questions with patience and professionalism. Mr. Rich, the dispatcher, even followed up with a call to clarify some information I had received regarding their regular maintenance plans and the service charges for my tankless water heater.The technician, Mr. Jesse Lance, was excellent—warm, professional, and efficient. He made me feel comfortable and completed the job thoroughly. I truly appreciate the care and quality service I received. I will definitely recommend Lanz Plumbing to others.

UPDATE: 7-8-25. Received a call the next day. I appreciate people and companies who are not afraid to admit a mistake was made. I understand things happen and I appreciate Lantz reaching out to me and explaining what happened. They didn’t have to but they made it right……thank you.FIVE stars for the Tech who did the work, he was great.Friendly and explained everything. Communication is highlighted on Lantz website but it was a major issue for me. Reported this problem on Saturday, received text advising someone would contact me soon. Never happened. Reported again on Sunday & received a call advising someone would be there around 5 or 6. No one showed up. Eventually received a call after 8 pm advising they would be there tomorrow. They eventually showed up at 5:30 pm on Monday. I bought the system from Lantz around 5 years ago and I pay the annual service (Orange). I expected better. 5 stars for the Tech 1 star for customer service.

Last year Lanz sent someone to fix a small leak in my Condensation drain line. This year there was a crack found in the connect from my condensation drain line to the cooler coil as a result of that pipe being cut from last year causing another leak.. I paid for the repair $314.I’m hoping for fair compensation due to this second leak as a result of previous work.. my condensation line was found clean and NOT CLOGGED this year and the pan was also clean.I also have water damage as a result of this leak.. there is mold present and my drywall and carpet is ruined as a result. I’m willing to accept/negotiate fair compensation! Please help

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!
