Some rooms never feel right. The basement stays cold all winter, the bonus room over the garage turns into an oven every July, and the addition you built never got tied into the ductwork. A ductless mini-split fixes that one space without tearing open walls or overworking your furnace and AC. Lenz Heating & Cooling has been installing and servicing heating and cooling systems across Greater Des Moines since 2009, with free estimates and our To-the-Penny Pricing Guarantee.

A ductless mini-split is a heat pump that heats and cools without ductwork. An outdoor unit connects to one or more indoor units mounted on the wall or ceiling through a small line set that runs through a hole about 3 inches wide. Each indoor unit has its own thermostat, so every room or zone runs at the temperature you choose.
Iowa basements tend to run cold in winter and damp in summer. A mini-split adds steady heat and cooling, and dry mode helps pull moisture out of the air.
Extending your existing ductwork is expensive and often leaves the new space short on airflow. A mini-split gives the room its own comfort without overloading your main system.
Many older Des Moines homes heat with boilers or radiators and have no ducts for central air. Ductless brings cooling into those homes without tearing open plaster walls.
If you spend real time in a space your main system doesn't reach, a mini-split makes it comfortable year-round.
Heat the room you're in, not the whole house.
No ducts means no air lost through leaky ductwork.
One unit covers summer and winter.
Indoor units run quieter than most window units and space heaters.
Most single-zone installs are finished in a day.
Yes. Cold-climate mini-splits are built to keep heating when outdoor temperatures drop well below zero. Like any heat pump, they lose some efficiency in the coldest stretches of January, so we size every system for Central Iowa winters and plan backup heat where it makes sense. If your home already has a furnace, a mini-split can take the load off one problem area while your main system handles the rest.
We measure the room, check insulation and sun exposure, and size the system to fit. We don't guess.
With our To-the-Penny Pricing Guarantee, you never pay more than the quote.
We place the indoor unit, run the line set, and mount the outdoor unit with as little disruption as possible.
Before we leave, you'll know how to use the remote, the modes, and the filter.
Ductless systems need care too. Clogged filters, dirty coils, and drain line problems are the most common reasons a mini-split stops heating or cooling well. Our technicians service, clean, and repair ductless systems, including ones we didn’t install. A Lenz Service Agreement keeps your system on a regular maintenance schedule, and we call you when it’s time.
From our offices in Urbandale and Waukee, we install ductless mini-splits throughout Des Moines, West Des Moines, Urbandale, Clive, Waukee, Ankeny, Johnston, and Altoona.
It depends on the number of zones, the size of the space, and the equipment. A single-zone system costs much less than a multi-zone setup for the whole house. We give you a free in-home estimate and a fixed price before any work starts.
Yes. A multi-zone system connects one outdoor unit to two or more indoor units, and each room has its own temperature control.
With regular maintenance, most ductless systems last 15 to 20 years.
Rinse the indoor unit filters about once a month during heavy use. A professional tune-up once a year keeps the coils and drain line clean.
For a single room or an addition, usually yes. Extending ducts is often expensive and can steal airflow from the rest of the house. We’ll tell you honestly which option fits your home.
Yes. Flexible financing is available on new ductless installations. See financing options →
