Our Service Promise: Speed, Efficiency, and Transparency

When you invest in a new heating system, you are buying more than a metal box; you are purchasing the installation quality that determines the unit's lifespan and efficiency. A furnace installed incorrectly will fail prematurely, regardless of the brand rating. Our approach focuses on technical precision and transparency from the moment we arrive at your property.

We begin with a comprehensive assessment of your home’s heating load. Many homes in the region have furnaces that are either oversized, leading to "short cycling" and high wear, or undersized, resulting in a unit that runs continuously without reaching the desired temperature. We utilize industry-standard Manual J load calculations to determine the exact heating requirements based on square footage, insulation levels, window quality, and local climate data.

Once the correct unit is selected, our team manages the entire logistical process. This includes the safe disconnection of gas lines and electrical high-voltage wiring, the removal and environmentally responsible disposal of your old unit, and the preparation of the installation site. We protect your flooring and property throughout the process, using drop cloths and shoe covers to ensure we leave your home cleaner than we found it.

Transparency is critical during this phase. You will receive a clear timeline and a fixed quote before work begins. There are no hidden fees for ductwork modification or unexpected venting requirements. We explain exactly what is included in the installation package, from the new thermostat integration to the condensate drain piping, ensuring you have a complete understanding of the scope of work.

Understanding the Installation Process: What to Expect

A professional furnace installation involves a series of technical steps designed to ensure safety, efficiency, and compliance with local codes. We do not skip steps or cut corners. A rigorous process protects your investment and ensures your family’s safety against hazards like carbon monoxide leaks or electrical fires:

• Site Evaluation and System Sizing: The process starts with a detailed evaluation. We inspect existing ductwork for leaks or damage that could impede airflow. We also verify that the gas line is sized correctly for the BTU input of the new furnace. If you are switching from an 80% efficiency unit to a high-efficiency 90%+ condensing furnace, we plan for new PVC venting and condensate drainage, as these units function differently than older standard-efficiency models.
• Removal of Existing Equipment: Safety is paramount during removal. Technicians shut off gas and electrical supplies before disconnecting the old furnace. We carefully disconnect the plenum (the box connecting the furnace to the ductwork) and the flue pipe. The old unit is removed from the premises for recycling. We then inspect the sub-floor and surrounding area for any moisture damage or structural issues that need addressing before the new unit is set in place.
• Positioning and Connection: The new furnace is leveled and positioned to minimize vibration and noise. We fabricate or modify the sheet metal plenum to ensure an airtight seal with the new unit. Air leaks at the furnace can cause significant energy loss and pull dust or debris into the system. We use professional-grade mastic sealant and foil tape to seal all connections.
• Venting and Gas Piping: Proper venting is critical. For high-efficiency units, we install dedicated intake and exhaust pipes that run to the exterior of the home. Gas lines are reconnected using a new sediment trap (drip leg) to prevent debris from entering the gas valve. All gas connections are pressure-tested and soap-tested to ensure there are absolutely no leaks.
• Electrical and Control Wiring: We connect the high-voltage electrical supply and the low-voltage thermostat wiring. If you are upgrading to a communicating system or a smart thermostat, we ensure the wiring harness is compatible and properly configured to utilize the advanced features of your new heater, such as variable-speed blower control or modulation.
• Commissioning and Testing: The installation is not complete until the system is commissioned. We fire up the furnace and measure the static pressure in the ductwork to ensure the blower motor is not overworking. We check the temperature rise (the difference between air entering and leaving the furnace) to confirm it falls within the manufacturer’s specified range. Finally, we perform a combustion analysis to verify optimal fuel burning and safe carbon monoxide levels.

Making the Right Choice: Repair vs. Replacement

Deciding between repairing an aging furnace or investing in a new installation is a common dilemma for homeowners. While repairs can offer a short-term fix, there is a financial tipping point where replacement becomes the more economical choice. Making this decision requires a logical look at the numbers and the condition of your current system:

• The 50% Rule: A general industry standard is the 50% rule: if the cost of the repair approaches 50% of the value of a new system, replacement is usually the better investment. For example, replacing a cracked heat exchanger or a failed compressor in an old unit is expensive. Putting that money toward a new unit with a fresh warranty often yields a better return on investment.
• Age of the Equipment: The average lifespan of a gas furnace is between 15 and 20 years. If your unit is approaching or has surpassed the 15-year mark, parts will become harder to find and more expensive. Even if a repair is successful, an older unit is running on borrowed time. Newer models are significantly more efficient, meaning monthly savings on utility bills can help offset the cost of installation.
• Rising Energy Bills: If you have noticed a steady increase in your heating costs despite normal usage, your furnace’s efficiency has likely degraded. Older furnaces often operate at 60-70% AFUE (Annual Fuel Utilization Efficiency), meaning 30-40 cents of every dollar you spend on gas is wasted up the flue. Modern standard units start at 80%, and high-efficiency models can reach up to 98%, converting nearly all fuel into usable heat.
• Frequency of Breakdowns: Reliability is a key factor. If you have required multiple service calls in the last two years, your system is becoming a money pit. The stress of uncertain reliability during a freezing night in Louisville is a significant factor. A new installation provides peace of mind and reliable performance when you need it most.
• Safety Concerns: Older furnaces are at higher risk for heat exchanger cracks, which can leak carbon monoxide into your home. If a technician flags a safety issue regarding the combustion chamber, replacement is the only responsible option. We prioritize your safety and will clearly explain why a unit is deemed unsafe for operation.

Adhering to Louisville Regulations: Permits and Seasonal Advice

Operating in Jefferson County requires strict adherence to local building codes and safety regulations. Furnace installation is not a DIY project; it involves dangerous components like natural gas, high-voltage electricity, and combustion gases:

• Permitting and Inspections: Local codes require permits for HVAC replacements to ensure the work meets safety standards. This often involves a post-installation inspection by a local code official. We handle the permitting process for you, ensuring that the installation complies with all mechanical codes regarding venting clearances, gas piping materials, and electrical disconnects. This compliance is vital not only for safety but also for future home sales, where unpermitted work can kill a deal.
• Combustion Air Requirements: Modern homes are built tighter than older ones, which can starve a furnace of the air it needs to burn fuel safely. Local codes specify how much combustion air must be available. In some cases, we may need to install fresh air intakes or transfer grilles to bring in outside air, ensuring your furnace doesn't create negative pressure in your home or backdraft dangerous gases.
• Seasonal Considerations: In our region, the weather can turn quickly. The ideal time for installation is typically early autumn before the first hard freeze. However, we are equipped to handle emergency replacements in the dead of winter. The local climate is humid subtropical, which affects how we set up your system. During the winter, the air can get dry, but in the shoulder seasons, humidity control is essential. We can configure variable-speed furnaces to help dehumidify your home more effectively when paired with your air conditioning system in the summer.
• Utility Rebates and Incentives: Local utility providers often offer rebates for upgrading to high-efficiency equipment. We stay updated on current rebate programs available to residents in the area and can help you navigate the paperwork to claim any available savings. This can significantly reduce the net cost of upgrading to a premium, high-efficiency system.
