The maintenence program is wonder. They check everything!! They provide all filters and send them ahead so they are ready. I pay a monthly fee and it is so worth it.

Really expensive for 15 minutes of work and some putty ($300) but I guess you pay for the expertise. The technician was professional, pleasant and on-time.

Three young men From Lanz Came today too check my furnace and also plumbing for fall. Their names were Gerald, Tony, and one other nice young man that was in training for plumbing. Sorry, I can’t remember his name for some reason. They were efficient, pleasant, and professional. I was very pleased and would recommend them highly.

Lanz is generally trustworthy and efficient. They have been servicing our plumbing and heating for more than twenty years. One main reason I like Lanz, especially in recent years, is because of Boston, their plumber. He is professional, knowledgeable, and unfailingly polite and thoughtful. He is always efficient and careful in his repair work. And in one instance he tried to repair our leaking toilet three times, and free for two times. Only when it still didn’t work, without pushing us, he recommended replacing it.

Was told putting a shark it’s fitting with stop was going to cost me over $200.00 which is ridiculous for a 10 minute maximum install. If it had been $50.00-$75.00 I would have given the ok, but I refused to pay over $200.00 ( and that was with my supposed 25% discount). When they left I fixed it myself in ten minutes with a part I bought at Ace for $14.99!! I appreciate your services but you shouldn’t charge that much for replacing a simple stop. Last spring you installed my own sump pump and I don’t think I paid over $125.00 for that job which entailed a whole lot more labor.

20:07 22 Sep 25

Outstanding HVAC and plumbing! We recently switched from another provider and couldn’t be happier with Lanz-joined their year-round program, which is a great deal.

Recently I purchased a new central air conditioning system from Lanz. The salesperson Kurt was so patient, answered all my questions and found a system that was perfect for my house. The Lanz crew did the removal of my old system and installed my new system quickly and everything is working great! Lanz also included a free check of my new air conditioning system a bit after installation. Thomas came over and double-checked everything and was also very patient and answered all my questions. I can't say enough good things about all the people I worked with in getting this new A-C system! I recommend Lanz to everyone! Thank-you so much!!

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.

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!

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.

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.
