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.

These guys are just the best! I’m old and live alone. They answer all my questions and share any incite they have. They’re also personable and polite.
