Interesting that they don't carry filters.A tad of an inconvenience for home owner to have to be there 2xs..also an added expense to your company to send someone out 2xs

From start to finish they are sharp, on point, absolute pros. I sought out several bids and their salesman was bright, informed, and THOROUGH. I was amazed when he wanted to look in crawl space and in attic. Other folks didn't do that, didn't ask questions he did. He was a problem solver. The big example was suggesting dehumidifier in crawl and it has made a world of difference. He sat down with a computer and went through the numbers. I needed larger return airs, for instance, more flow. Everything made sense. And he was patient when I had him generate multiple bids through my uncertainty and budgeting. These folks fixed several complaints I've had about this house in the 4 years I've been here. The lead install man came and did measurements and scoped out the project before install day came - he was prepared. The gentlemen installing were polite, respectful, sharp. I've had the system a couple weeks and the whole thing has changed the atmosphere in my home. Humidity control, proper sized AC and furnace and wow, what difference. I've already suggested this company to a couple other friends and family. It is rare in 2025 to find absolutely serious, on point, service-oriented folks like this. If you want every detail done right, call Lanz.

Had a faucet that stopped working and water was draining continuously. Made a call early morning and a receptionist took call. Had someone come in same day from Lanz by noon. Everything was well taken care of and Kyle from Lanz was very helpful. Great company to work with and their service is great.

Outstanding Service from Start to Finish! I recently had a new furnace and air conditioner installed, and I couldn't be more pleased with the entire Lanz experience. From the first consultation with Wes, the service was exceptional. Wes and the team arrived punctually for the installation. They were respectful of my home—wearing boot covers and cleaning up thoroughly when done. They answered all of my questions with patience and expertise. A huge thank-you to Lanz for their customer service!

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.

Margaret Ballantyne

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.

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.
