How Long Does Furnace Replacement Take in Garrett, IN? Timeline & What to Expect
When your furnace starts failing, one of the first questions most homeowners ask is how long does furnace replacement take? If you’re planning a furnace replacement in Garrett, IN, knowing the timeline ahead of time can help you prepare your home, your schedule, and your expectations. While every home is different, most furnace replacements follow a fairly predictable process.
In this guide, we’ll walk through the average time it takes to replace a furnace, what can speed things up or slow them down, and what you can expect on installation day when you work with T&T Plumbing & Heating, Inc.
Average Furnace Replacement Timeline
In most Garrett homes, furnace replacement can be completed in a single day. For a straightforward furnace installation, most replacements take between 4 and 8 hours from start to finish. This includes removing the old unit, installing the new furnace, connecting it to existing ductwork, testing the system, and making sure everything is running safely and efficiently.
That said, not every furnace replacement fits neatly into that window. Some installations take longer, especially if changes like gas line modifications, ductwork modifications, or electrical upgrades are involved. Others may move faster if the setup is simple and the home already has modern connections in place.
When homeowners ask, “How long does furnace replacement take?”, the most accurate answer is “it depends,” but understanding the factors involved can help clarify what that means for your home.
What Affects How Long Furnace Replacement Takes?
Several factors can influence the timeline of a furnace replacement. The following needs are assessed when planning for the furnace installation process so we can give you an idea of how long it will take.
Type of Furnace Being Installed
Replacing an older furnace with a similar model usually takes less time than switching fuel types or upgrading efficiency levels. For example, replacing standard natural gas furnaces with another gas furnace is typically faster than switching from electric furnaces to gas or installing high-efficiency furnaces that require additional venting.
Condition of Existing Ductwork
If your ductwork is in good shape and properly sized, installation moves much faster. However, if ducts need repairs, sealing, or resizing to match the new furnace, the job may take longer. Proper airflow is critical for performance and safety, so this step should never be rushed.
Upgrades to Electrical or Gas Connections
Older homes in Garrett may need updates to electrical wiring, gas lines, or venting systems to meet current safety codes. These updates add time but are important for protecting your home and improving the long-term reliability and energy efficiency of the new furnace.
Location of the Furnace
Furnaces installed in tight basements, crawl spaces, or utility closets may take longer to replace than units in open mechanical rooms. Limited access can slow down removal and installation.
Pre-Installation: What Happens Before Installation Day
Before the installation team arrives, there are several steps we take to make sure the process runs smoothly.
First, a professional assessment is done to confirm the right furnace size for your home. Proper sizing prevents short cycling, uneven heating, and unnecessary energy costs. Once the right system is selected, we’ll schedule the replacement and order the equipment.
At this stage, homeowners often ask again, “How long does it take to replace a furnace?” This is when you’ll receive a clearer estimate based on your home’s layout and the type of furnace being installed.
Installation Day: What to Expect Step by Step
Knowing what happens during furnace replacement before the installation process begins can make the day feel less disruptive.
1. Arrival and Preparation
Technicians arrive with the new furnace and necessary tools. Floors and nearby areas are protected to keep your home clean.
2. Removing the Old Furnace
The existing furnace is safely disconnected from power, gas, and ductwork. It’s then removed from your home. This step typically takes one to two hours, depending on size and accessibility.
3. Installing the New Furnace
The new furnace is positioned and secured at the installation site, then connected to ductwork, gas lines, electrical components, and venting. This is the most time-intensive part of furnace replacement and usually takes several hours.
4. System Testing and Calibration
Once installed, the furnace is tested to ensure proper airflow, ignition, thermostat communication, and safety controls. Adjustments are made to optimize performance and efficiency.
5. Final Walkthrough
Before leaving, technicians explain how your new furnace works, review thermostat settings, and answer any questions you have.
Other Questions You May Have About the Furnace Replacement Process
When you’re planning a furnace replacement, it’s normal to have questions beyond just how long the installation takes. Here, we’ll answer some of the most common questions people have about the furnace replacement process, so you can feel confident, informed, and ready to move forward.
Will You Be Without Heat During Furnace Replacement?
Yes, your home will be without heat during the installation process. However, since furnace replacement typically takes less than a full day, the downtime is usually minimal. Many homeowners schedule replacements during milder weather when possible, but even winter installations are handled efficiently to restore heat as quickly as possible.
If your furnace has failed completely, a prompt replacement can prevent extended discomfort. Planning ahead helps ensure the shortest possible downtime.
How Long Does Furnace Replacement Take Compared to Repairs?
Furnace replacement often takes about the same amount of time as a major repair, but the long-term benefits are very different. While repairs may temporarily restore heat, an aging furnace may continue to break down. Replacement provides peace of mind, improved efficiency, and better comfort for years to come.
If you’re facing frequent repairs, asking how long does furnace replacement take often comes up when deciding whether replacement is the smarter option.
Do I Need to Be Home the Whole Time?
Yes, it’s best to be home during your furnace replacement, especially at the beginning and end of the installation. Being there allows you to give technicians access to your home, review the scope of work, and ask any last-minute questions before the old furnace is removed. At the end of the job, you’ll also have a walkthrough of the new system, thermostat settings, and basic operation.
That said, you don’t usually need to stay nearby the entire time. Once the work is underway and access is established, many homeowners choose to run errands if there is another adult present at home, or work from another part of the house. As long as technicians can reach you if needed, we can often be flexible.
