A smart thermostat can cut wasted energy, learn your schedule, and let you adjust your home’s temperature from your phone. But it only works as well as it’s set up. If it’s wired or configured wrong, it can short-cycle your system, run backup heat when it doesn’t need to, or stop talking to your equipment altogether. Lenz Heating & Cooling installs and sets up smart thermostats across Greater Des Moines so they work the way they should with the system you already have.

ENERGY STAR estimates that a certified smart thermostat saves about 8% on heating and cooling bills. In a climate like ours, with hard winters and humid summers, that adds up.
Many smart thermostats are sold as do-it-yourself products, and in some homes that works fine. In others, small wiring and setup mistakes cause real problems. We recommend professional installation if:
Most smart thermostats need a common wire (C-wire) for steady power. Without one, the thermostat can drop its Wi-Fi connection, drain its battery, or make your system turn on and off on its own. We can run a new wire or install an adapter the right way.
Heat pumps need the thermostat set up correctly for the reversing valve and auxiliary heat. If it's configured wrong, your expensive backup heat strips can run when the heat pump could handle the load, and your electric bill climbs without you knowing why. Learn more about our heat pump services →
A heat pump paired with a gas furnace needs a thermostat that knows when to switch between them. We set the changeover point for Central Iowa winters so you get efficient heat without running the wrong system.
Two-stage furnaces, variable-speed equipment, and zoned systems need the right thermostat and the right settings to deliver the comfort you paid for.
We look at your equipment and wiring before anything comes off the wall.
If you need a C-wire, we add it.
We configure heating stages, heat pump settings, fan control, and your schedule.
Before we leave, the app is connected and you know how to use it.
Every installation comes with our To-the-Penny Pricing Guarantee: you never pay more than the price we quote.
A smart thermostat can’t fix a system that isn’t working right. If your furnace, AC, or heat pump hasn’t been serviced in a while, a tune-up at the same visit makes sure your new thermostat is controlling equipment that runs efficiently. With a Lenz Service Agreement, we call you when it’s time for maintenance.
Installing a new heating or cooling system? We’ll match it with the right thermostat as part of the installation.
From our offices in Urbandale and Waukee, we install smart thermostats throughout Des Moines, West Des Moines, Urbandale, Clive, Waukee, Ankeny, Johnston, and Altoona.
Most smart thermostats work with standard furnaces, air conditioners, and heat pumps. Some systems, like dual-fuel setups, multi-stage equipment, and older millivolt systems, need a specific model or extra wiring. We check compatibility before we install anything.
A C-wire is a common wire that gives your thermostat constant power. Most smart thermostats need one to work reliably. If your home doesn’t have one, we can add it.
Yes. We can install and set up a thermostat you bought yourself, as long as it’s compatible with your system.
ENERGY STAR estimates about 8% savings on heating and cooling bills with a certified smart thermostat. Your actual savings depend on your home, your system, and how you use it.
It’s often a thermostat setup problem. If the thermostat isn’t configured for your heat pump, it may call for backup heat too often, which costs much more to run. We can check and correct the settings.
Since 2009, Des Moines families have counted on Lenz to keep their homes comfortable in July heat and January cold. Tell us what you need, and we’ll show you whether a heat pump fits your home.
