What You Get With a Modern HVAC Upgrade

Replacing a heating and cooling system is more than just swapping out a metal box; it is an investment in the long-term comfort and energy efficiency of your home. When you move forward with an installation today, you are purchasing a complete environmental control system designed to handle the specific thermal loads of your property.

Modern systems are engineered to address issues that older units simply cannot manage. A new installation includes the removal and environmentally safe disposal of your existing equipment, ensuring that all refrigerants and materials are handled according to EPA regulations. Following the removal, the focus shifts to the installation of high-efficiency equipment. This typically involves a new furnace, air conditioner, or heat pump, along with a matched indoor coil and thermostat.

Newer units operate with significantly higher SEER2 (Seasonal Energy Efficiency Ratio) and AFUE (Annual Fuel Utilization Efficiency) ratings. This translates to reduced electrical and gas consumption, which is vital for managing utility costs throughout the year. Beyond the main units, a standard replacement also covers the essential peripheral components that ensure the system runs smoothly. This includes the transition ductwork to connect the new unit to your existing air distribution system, new refrigerant lines or flushed existing lines, a new filter drier to protect the compressor, and a leveled condenser pad to prevent vibration and settling.

We also focus on the "lungs" of the system. If your existing thermostat is outdated, it is replaced with a programmable or smart thermostat that allows for precise temperature control and scheduling. This ensures that the system runs only when necessary, further extending the lifespan of the equipment. The goal is to leave you with a system that provides consistent airflow, balanced temperatures in every room, and a noticeable reduction in operational noise.

The Installation Process: From Assessment to Airflow

A professional installation is a systematic process designed to minimize disruption to your home while maximizing the performance of the new equipment. We adhere to a strict protocol to ensure that every installation meets manufacturer specifications and safety standards.

• Load Calculation and Sizing: The process begins with a detailed assessment of your home. We do not guess the size of the unit based on what was there before. Using Manual J load calculations, we analyze the square footage, insulation levels, window types, and orientation of your home. This ensures the new unit is perfectly sized. An oversized unit will short-cycle and fail to dehumidify, while an undersized unit will run continuously without reaching the set temperature.
• Site Preparation and Protection: Before any heavy lifting begins, the workspace is prepped. Technicians lay down drop cloths and floor protectors to ensure your home remains clean. We turn off gas and electrical supplies to the existing unit to ensure a safe working environment.
• System Removal: The old equipment is disconnected. If it is an air conditioner or heat pump, the refrigerant is recovered into a specialized tank rather than being vented into the atmosphere. The old furnace, evaporator coil, and outdoor condenser are then carefully removed from the property.
• Ductwork and Plenum Inspection: Once the old unit is out, the existing ductwork and plenum (the box connecting the unit to the ducts) are inspected. If there are air leaks or damage, these are addressed to prevent conditioned air from escaping into the attic or crawlspace. The new plenum is then custom-fabricated or adapted to ensure an airtight fit with the new equipment.
• Equipment Placement and Connection: The new furnace or air handler is positioned and leveled. The outdoor condenser is placed on a new, stable pad. Technicians then braze the copper refrigerant lines, flowing nitrogen through the lines during the process to prevent oxidation and future blockages.
• Electrical and Gas Hookup: High-voltage and low-voltage electrical connections are established, ensuring the thermostat communicates correctly with the heating and cooling elements. For gas furnaces, the gas piping is connected, and a sediment trap is installed if one is not already present. All connections are tested for leaks.
• Vacuum and Charge: A vacuum pump is attached to the refrigerant lines to remove moisture and air, creating a deep vacuum. This is a critical step for the longevity of the compressor. Once the vacuum holds, the system is charged with the precise amount of refrigerant required by the manufacturer.
• Commissioning and Testing: The system is powered on and put through a full cycle. Technicians measure static pressure, temperature rise (for heating), and subcooling/superheat (for cooling) to verify the system is operating at peak efficiency.

When Replacement Beats Repair

Deciding between repairing an aging system and investing in a replacement is a common dilemma. While repairs can solve immediate issues, there is a tipping point where pouring money into an old unit becomes financially unwise.

• The 50% Rule: A general guideline used in the industry is the 50% rule. If the cost of the repair approaches 50% of the value of the system or the cost of a new unit, replacement is generally the better option. Major failures, such as a cracked heat exchanger or a blown compressor, often fall into this category.
• System Age: HVAC systems typically last between 10 and 15 years. If your unit is in this age range and requires a significant repair, it is nearing the end of its useful life. Investing in a repair at this stage buys limited time before another component fails.
• Rising Energy Bills: As systems age, they lose efficiency due to wear and tear on motors and compressors. If you notice a steady increase in your heating and cooling bills despite normal usage, the system is likely working harder to produce the same amount of air. A modern system can drastically reduce these monthly expenses, helping the new unit pay for itself over time.
• Frequency of Breakdowns: If you are calling for service multiple times a year, the system has become unreliable. The cumulative cost of service call fees and minor repairs often exceeds the monthly payment of a financed new system.
• Comfort and Air Quality: Old systems often struggle to maintain consistent temperatures, leading to hot and cold spots in different rooms. They may also be less effective at humidity control. If your home feels clammy in the summer or excessively dry in the winter, the equipment is likely failing to condition the air properly.
• Refrigerant Type: Older air conditioners utilize R-22 (Freon), which has been phased out due to environmental regulations. Supplies of R-22 are dwindling and extremely expensive. If your R-22 system develops a leak, replacement is almost always the only logical financial choice, as the cost of recharging the system is prohibitive.

Navigating Local Climate and Building Requirements

Operating an HVAC system in this region requires equipment that can handle a humid continental climate. We experience four distinct seasons, each presenting unique challenges to your heating and cooling infrastructure.

• Handling High Humidity: Summers in Floyds Knobs are notably hot and humid. High humidity can make the air feel significantly warmer than the thermostat reading, forcing your AC to run longer. Proper installation here requires careful attention to the dehumidification capabilities of the cooling unit. We often recommend two-stage or variable-speed compressors for this area, as they run for longer, lower-intensity cycles that effectively pull moisture from the air without overcooling the space.
• Winter Resilience: With winters seeing temperatures drop below freezing and average snowfall reaching 15-20 inches, your heating source must be absolutely reliable. Heat pumps are a popular choice, but in our climate, they often need to be paired with a gas furnace (dual fuel system) or electric heat strips to handle the coldest nights when the ambient air temperature drops below the efficiency threshold of the heat pump.
• Permitting and Code Compliance: HVAC installations are significant home improvements that are subject to local building codes and safety regulations. In Indiana, permits are generally required for the installation of new heating and cooling equipment to ensure the work meets safety standards. This includes verifying proper venting for gas furnaces to prevent carbon monoxide buildup and ensuring electrical circuits are properly sized for the new equipment.
• Utility Requirements: We coordinate with local utility providers to ensure your new system is compatible with your current service. Whether your home relies on Duke Energy, REMC, or other local providers, we ensure the electrical service panel has the capacity to support your new AC or heat pump. We also assist homeowners in identifying available rebates for high-efficiency units, which are often offered by utility companies to encourage energy conservation.

At Allegiance Heating & Air, LLC., we handle the logistics of permits and compliance, ensuring that your installation is not only high-performing but also fully legal and safe.

Technical Precision and Safety Protocols

The difference between a system that lasts 10 years and one that lasts 20 often comes down to the quality of the installation. We prioritize technical precision over speed. Every connection, from the low-voltage wiring to the gas piping, is double-checked for integrity.

• Advanced Diagnostics: We utilize digital manifolds and micron gauges during installation. This digital accuracy ensures the refrigerant charge is exact to the ounce and the vacuum pulled is deep enough to remove all non-condensables. Analog gauges simply cannot provide the level of precision required for modern, high-efficiency equipment.
• Airflow Verification: A unit can only perform as well as the ductwork allows. We measure static pressure—the resistance to airflow—within your system. If the pressure is too high, it puts strain on the blower motor. We adjust fan speeds and, if necessary, recommend duct modifications to ensure the system "breathes" easily.
• Safety First: Gas furnaces involve combustion, which produces carbon monoxide. We meticulously check the heat exchanger and venting system. We also inspect the gas line for any potential leaks using electronic sniffers. For electrical systems, we ensure all wire gauges are correct and connections are tight to prevent overheating or fire hazards.
• Warranty Registration: Manufacturer warranties are often contingent on professional installation and registration within a specific timeframe. We handle the registration process for you, ensuring that you receive the full benefit of the parts and compressor warranty.
