What We Do

Four divisions, one phone number

Most contractors hand you off. Lanz started as a heating and cooling company in 2002, added service in 2005, then plumbing, duct cleaning, commercial refrigeration, and underground. Today one call reaches all of it.

Our Story

From one truck to 115+ neighbors

Troy Lanz spent 16 years in the HVAC trade before starting his own company in 2002, installing residential heating and cooling systems around Champaign-Urbana. Kathleen Lanz built the customer-first side of the business, and that philosophy has survived every expansion since.

A service department came in 2005. Then plumbing. Then duct cleaning, commercial HVAC, refrigeration, and finally the underground division that lets us repair a sewer main without digging up your parking lot. Today more than 115+ employees run roughly 90 service vehicles across Illinois and Arizona.

What did not change: honest, transparent pricing, and the promise to recommend only the work we genuinely believe you need. Every job is backed by a 100% satisfaction guarantee.

Honesty
Transparent pricing before the work starts, and only the repairs we would recommend to our own family.
Integrity
We do what we said we would do, on the day we said we would do it.
Innovation
Trenchless pipelining, high-speed descaling, geothermal — we invest in equipment that saves you excavation.
Teamwork
HVAC, plumbing, and underground crews under one roof, so one call covers the whole problem.
Excellence
Every install is backed by a 100% satisfaction guarantee and a one-year labor warranty.
Development
Ongoing factory and field training for 115+ employees keeps our techs current on the equipment in your home.

Straight Answers

Questions we get asked

Do you charge extra for nights, weekends, or holidays?

No. Lanz answers the phone 24 hours a day, seven days a week at 217-394-1380, and there is no additional fee for after-hours emergency service. Comfort Family members also get priority scheduling and no emergency dispatch fee at all.

What areas does Lanz serve?

Our Illinois team works out of Champaign and covers Champaign, Urbana, Savoy, Monticello, St. Joseph, Rantoul, Mahomet, Tolono, and the surrounding Central Illinois communities. Our Arizona division operates out of Tolleson and serves Goodyear, Avondale, Buckeye, and the greater Phoenix West Valley. If you do not see your town listed, call us — we very likely cover it.

How often should I have my heating and cooling system maintained?

Twice a year. Heat pumps and air conditioners should get a professional tune-up in the spring and again in the fall. Preventive maintenance catches leaks, rust, soot, frayed wires, and corroded electrical contacts before they turn into a no-heat call in January. Comfort Family membership bundles both visits into one monthly rate.

How often should I change my furnace filter?

Replace a standard disposable filter every month. Media filters trap up to seven times more dust than a standard filter, and pleated media filters also capture fine particles and airborne viruses. If you cannot find the right size at a hardware store, that is normal — filters for Trane equipment are made from higher-grade material and come through an authorized dealer like us.

What is a SEER rating, and why does the number my dealer quotes differ from the Energy Guide label?

SEER stands for Seasonal Energy Efficiency Ratio, and it measures how much cooling you get per dollar of electricity. Ratings generally run from 13 to 21, and higher is more efficient. The reason the quoted number can differ from the yellow Energy Guide sticker is that SEER is a rating for the matched system — the outdoor unit combined with the specific indoor coil, furnace, or air handler it is paired with.

What is trenchless pipe repair, and is my property a candidate?

Trenchless methods repair or replace a pipe with little or no excavation. Directional boring pulls a new line underground without opening a trench, and pipelining rehabilitates the existing pipe from the inside with a cured epoxy liner. Our crews are NASSCO-certified drain professionals with PACP-certified inspectors, so the process starts with a camera inspection that tells us exactly what shape the line is in.

What does the warranty cover on a new system?

The manufacturer covers defective parts for the length of the factory warranty, and Lanz adds a one-year labor warranty on every new installation. Comfort Family members extend that labor coverage to as much as 10 years on new Trane equipment.

How do I get an estimate?

Call 217-394-1380 or send a message through the contact form on this page. For repairs we diagnose on site and give you the price before any work begins. For installations and underground projects we come out, look at the actual conditions, and put a written proposal in your hands. We also offer free second opinions on drain cleaning quotes.

Still stuck? Call 217-394-1380 — a person answers, any hour.
