When it comes to furnace installation, timing matters. If you’re planning to replace your old system in Kettering, OH, you’re likely wondering, “How long does it take?” The answer isn’t one-size-fits-all—it depends on several factors. Outstanding Heating & Cooling breaks down the timeline, step-by-step, to give you a clear idea of what to expect.

Preparation Before a Furnace Installation
Before the installation day, there’s prep work involved that ensures the process goes smoothly.
1. Initial Consultation and Assessment
The first step is scheduling an assessment with your HVAC contractor. Outstanding Heating & Cooling will evaluate your home’s heating needs, inspect your current HVAC system, and recommend the right furnace for your space. This typically takes an hour or two, but scheduling an appointment may take a few days depending on availability.
2. Choosing the Right Furnace
Once the assessment is complete, you’ll select your furnace based on size, energy efficiency, and budget. It’s important to choose a furnace that fits your home’s specific needs. Once the decision is made, ordering the furnace can take anywhere from a day to a week, depending on inventory.
3. Scheduling Your Kettering Furnace Installation
Coordinating schedules is the final step before the actual installation. Outstanding Heating & Cooling works with your availability, but in busy seasons (like winter), you might need to wait a few days. Once everything is set, the installation can move forward.
On Installation Day
The furnace installation process itself is usually completed in a single day. Here’s what happens step by step:
1. Arrival and Setup
On installation day, the technicians will arrive with all the necessary tools and equipment. They’ll protect your home by laying down drop cloths and prepping the workspace. Safety checks and HVAC equipment shutdowns (for replacements) are also completed during this time.
2. Removing the Old Unit
If you’re replacing an old furnace, the team will begin by disconnecting and removing it. This involves shutting off the power and gas, dismantling the old system, and clearing the area for the new furnace. The time required depends on the complexity of the removal process and whether there are any issues, like rusted components or difficult access.
3. Installing the New Furnace
The heart of the process is installing the new furnace. Technicians will:
- Position and secure the furnace.
- Connect ductwork, gas lines, and electrical wiring.
- Ensure proper ventilation and exhaust systems are in place.
The complexity of your home’s setup and the type of furnace being installed play a big role in how long this step takes. For example, a high-efficiency furnace with advanced features may require additional time for setup.
4. Testing and Calibration
Once the new HVAC system is in place, it’s time to test it. The team will turn the system on, check for proper operation, and fine-tune settings to ensure optimal performance. This includes checking airflow, thermostat settings, and safety features.
5. Post-Work Cleanup
Once the furnace is installed and tested, the technicians will clean up the work area. Outstanding Heating & Cooling prioritizes leaving your home as neat as they found it.
How Long Does It Take to Remove and Install a Furnace?
In general, the entire furnace installation process—from arrival to final testing—takes about 4 to 8 hours on installation day. However, when factoring in your consultation, scheduling, and ordering equipment, the full timeline can stretch from a few days to a couple of weeks, depending on availability.
How Many People Does It Take to Install a Furnace?
Installing a furnace typically requires a team of two to three skilled HVAC technicians. This team size allows for an efficient and thorough installation process, as each technician can focus on specific tasks such as removing the old system, positioning the new furnace, and connecting the ductwork, gas lines, and electrical components.
Having multiple technicians ensures the job is done safely and accurately while keeping the installation time to a minimum. With the right team, your furnace installation will be seamless and stress-free.
Factors That Can Impact Your Furnace Installation Time
Several factors can influence how long it takes to install your furnace:
Type of Furnace
High-efficiency furnaces and dual-fuel systems with heat pumps may require more time to install due to their complexity. Converting from an electric to a gas furnace can require additional time to install venting and gas lines.
Ductwork Modifications
If your home’s ductwork needs adjustments, repairs, or a complete overhaul, this can add hours—or even days—to the project.
Accessibility
The location of your furnace can make a big difference. For example, if it’s in a cramped basement or attic, the process may take longer.
Permits and Inspections
Local regulations in Kettering, OH, require permits and post-installation inspections for heating and cooling systems. These steps can add time to the overall process but are crucial for ensuring safety and compliance.
Additional HVAC Services
If you’re upgrading multiple components of your HVAC system, the timeline may extend. For example:
- Air Conditioner Replacement: If you’re installing a new air conditioning unit alongside the furnace, technicians can integrate both systems for maximum efficiency. However, this may add a few extra hours—or even an additional day—depending on the complexity of the installation.
- Indoor Air Quality Services: Enhancements like air purifiers, humidifiers, or UV lights can significantly improve your home’s comfort and health. Installing this equipment alongside your furnace ensures a seamless setup but requires extra time for integration and testing.
Unforeseen Issues
Occasionally, unexpected issues like outdated wiring or corroded gas lines can arise, adding extra hours to the job.
Tips for a Smooth Furnace Installation Process
To ensure everything goes as planned, follow these tips:
- Schedule Early: Don’t wait until the first snowfall—book your consultation in advance to beat the busy season.
- Clear the Area: Make sure the space around your furnace is accessible for the technicians.
- Ask Questions: Don’t hesitate to ask your HVAC provider about the timeline and any preparation steps you can take.
- Plan Ahead: If possible, arrange for family members or pets to stay in another part of the house during installation.
