Furnace Installation & Replacement in Des Moines, IA

Equipment Selection & Heating System Design

Once we understand your heating load, we present options. Furnaces come in different efficiency tiers: single-stage models are simpler and affordable; two-stage models run quieter and more efficiently on mild winter days; variable-stage models modulate output precisely to demand. We'll explain the trade-offs—upfront cost vs. long-term efficiency savings—and help you choose what makes sense for your budget and heating goals.

We'll also discuss fuel type. Most homes use natural gas—it's efficient and convenient. Some use propane or oil. We'll design your system for your fuel type and explain seasonal costs based on current utility rates. We'll also address your thermostat: do you want a basic programmable model, or would you prefer a smart thermostat that learns your schedule and adjusts automatically?

You'll receive a detailed written proposal with equipment specs, efficiency ratings (AFUE %), heating capacity (BTU), warranty coverage, installation timeline, and financing options.

What You'll Receive

Preparation & System Staging

Before installation day, we prepare your home. We'll assess the location where the new furnace will sit—usually a basement, mechanical room, or attic. We'll verify that gas lines, electrical supply, and ductwork are accessible and in acceptable condition. If ductwork repairs or sealing are needed, we'll discuss that upfront. We'll also plan for the removal and safe disposal of your old furnace.

We'll also schedule any prerequisites: gas line installation or conversion, electrical panel upgrades if needed, or ductwork modifications. We'll coordinate with utility companies if gas line work requires their involvement. We'll brief you on installation day logistics—where our crew will be working, how long the process takes, and any inconveniences you might experience during the switchover.

Preparation Checklist

Professional Furnace Installation & Gas Integration

Installation day is where expertise shows. Our technicians carefully position your new furnace, making sure it's level, properly supported, and positioned for optimal airflow. They connect the gas line with proper fittings and shutoffs, test all connections for leaks using soapy water and pressure testing, and verify proper gas supply. Electrical connections are made to code—the thermostat wire, 240V power supply (if applicable), and all safety interlocks are connected and verified.

They'll also connect your ductwork properly—sealed connections reduce air leaks, and the furnace must connect to both return and supply ductwork with proper airflow. If ductwork sealing or repairs are needed, they'll complete that work now. The venting system is carefully installed—exhaust gases must exit safely through the chimney or external vent, depending on your furnace type.

Once everything is connected, we'll run a startup test to verify the furnace ignites, burns cleanly, and reaches operating temperature. We'll also test safety interlocks—if something goes wrong, the furnace must shut down safely.

Combustion Analysis, Documentation & Your Training

Once the furnace is running, we perform a combustion analysis—a technical test that measures exhaust gases, carbon monoxide levels, and draft to verify the furnace is operating safely and efficiently. We'll also test airflow at all supply vents to ensure balanced heating throughout your home. We'll verify the thermostat is reading accurately and controlling the furnace properly.

We then walk you through furnace operation: how to set the thermostat, what sounds are normal (ignition clicks, fan ramp-up), how to recognize warning signs, and what to do if your furnace stops working. You'll receive all documentation—equipment manuals, warranty cards, service records, and the combustion analysis report. We'll also schedule your first maintenance appointment before we leave—typically a fall tune-up before heating season to ensure everything is ready.
