What to Expect from Our Furnace Installation Process

Investing in a new heating system is a significant decision that impacts your home’s comfort for the next 15 to 20 years. When you choose professional installation services in Corydon, you are purchasing more than just a piece of equipment; you are securing a comprehensive service designed to maximize the lifespan and efficiency of that equipment. We prioritize transparency and precision from the moment we arrive at your property.

A proper installation begins with a thorough assessment of your home’s thermal characteristics. We do not simply swap out the old box for a new one of the same size. Older units were often oversized, leading to short-cycling and inefficiency. Our team evaluates your ductwork, insulation levels, and the total volume of your living space. This ensures the new unit is perfectly sized to handle both the humid summers and the freezing winters typical of the region.

You can expect a streamlined timeline. In most residential scenarios, a full replacement is completed within a single day. Our technicians arrive with a fully stocked truck, protective gear for your flooring, and all necessary tools to complete the job without unnecessary delays. We handle the disconnection of gas lines, electrical wiring, and venting systems with extreme care, ensuring that your home remains safe throughout the transition.

Step-by-Step Guide to Your New Furnace Installation

Understanding the mechanics of a furnace replacement helps homeowners feel confident in the value they are receiving. We follow a rigorous, checklist-driven approach to ensure every component functions correctly and safely. This eliminates the risk of callbacks and ensures your system operates at peak efficiency from day one.

• Site Preparation and Safety Check: First, technicians prepare the workspace by laying down drop cloths and ensuring the area around the existing furnace is clear. We shut off fuel supplies—whether natural gas, propane, or electricity—and verify that all circuits are dead before touching any wiring. This phase also includes a preliminary inspection of the area for any pre-existing issues with mold, water damage, or structural concerns that might affect the new install.
• ‍Removal of Existing Equipment: Next, the old furnace is disconnected. This involves carefully uncoupling the plenum (the box that connects the furnace to the ductwork), venting pipes, gas lines, and electrical connections. The old unit is removed from the premises and disposed of according to environmental regulations. We also inspect the exposed evaporator coil (if you have central air) to ensure it is clean and compatible with the new furnace.‍
• Modification and Positioning: Then, we prepare the area for the new unit. Modern furnaces are often smaller physically but more efficient than older models, which may require fabricating a transition fitting for the ductwork. We level the surface where the furnace will sit to ensure proper drainage of condensate (especially for high-efficiency condensing furnaces) and quiet operation. The new unit is moved into place and leveled precisely.‍
• Connecting Critical Systems: After positioning, we reconnect the main systems. The supply and return plenums are sealed to the furnace to prevent air leaks. The flue pipe is installed or upgraded to meet current safety codes; high-efficiency models often require PVC venting out the side of the home rather than through the chimney. Gas lines are reconnected with a sediment trap (drip leg) to protect the gas valve, and electrical wiring is attached, including the thermostat control wires.‍
• Commissioning and Testing: Finally, the system is fired up. We do not just turn it on and leave. We perform a combustion analysis to measure oxygen and carbon dioxide levels, ensuring the fuel is burning cleanly and safely. We check the temperature rise—the difference in air temperature between the return and supply—to confirm it falls within the manufacturer’s specifications. We also test safety switches, including the high-limit switch and flame sensor, to verify they will shut the unit down in an emergency.

Deciding Between Furnace Repair and Replacement

Homeowners often struggle with the decision to repair an aging unit or invest in a new one. While repairs can seem cheaper upfront, they are often a sunk cost if the system is nearing the end of its useful life. In the variable climate of Indiana, where a heating failure can be dangerous, reliability is the primary factor.

You should consider replacement if your furnace is over 15 years old. The average lifespan of a forced-air furnace is between 15 and 20 years. Beyond this age, heat exchangers can crack, which poses a carbon monoxide risk, and parts become obsolete or prohibitively expensive. If your unit has not been maintained regularly, this timeline shrinks significantly.

Review the frequency and cost of recent repairs. A common industry standard is the "50% Rule": if the cost of the repair approaches 50% of the value of a new system, replacement is the smarter financial move. Additionally, if you have required multiple service calls in the last two years, it indicates that internal components are failing in a cascade. Allegiance Heating & Air, LLC. can provide a detailed cost-benefit analysis to help you make this determination based on facts, not guesswork.

Monitor your energy bills. As furnaces age, they lose efficiency. An 80% AFUE furnace installed in 2005 may now be operating at 60% or 70% efficiency due to wear and tear. Replacing it with a modern 96% AFUE unit means 96 cents of every dollar spent on gas goes directly into heating your home. This efficiency gap often results in savings that offset the monthly cost of financing a new installation — check our specials for current offers.

Compliance and Considerations for Local Climate

Operating a heating system in Harrison County requires specific attention to local climate patterns and building regulations. The freeze-thaw cycles and heavy snowfall typical of Corydon winters put significant stress on intake and exhaust pipes.

• Venting Requirements: High-efficiency furnaces produce condensation that must be drained. In our climate, if the drain lines run through an unconditioned space (like a crawlspace or attic), they must be insulated or heat-taped to prevent freezing. Blocked condensate lines will shut down the furnace instantly to prevent water damage. Furthermore, intake and exhaust vents on the exterior of the home must be positioned high enough to avoid being blocked by snow drifts, which is a critical safety consideration during January and February storms.‍
• Permitting and Inspections: Installation is not the Wild West; it is a regulated construction activity. Local codes dictate specific requirements regarding gas line sizing, electrical grounding, and clearance distances from combustible materials. Securing the proper permits ensures that the installation is recorded and inspected by a third-party official. This is vital for your home insurance coverage and future resale value. Professional installers handle the paperwork and scheduling of these inspections so you remain compliant without the administrative headache.‍
• Humidity Control: Our winters are dry. A standard furnace dries out the air even further, which can lead to static electricity, dry skin, and respiratory issues. Many local homeowners choose to integrate a whole-home humidifier during the furnace installation process. Doing this simultaneously saves on labor costs and ensures the humidifier is hardwired into the furnace controls for automatic operation based on the outdoor temperature.
