When you invest in a new air conditioning system, you are purchasing more than just a piece of machinery; you are securing the future comfort and energy efficiency of your home. The modern installation process is comprehensive, ensuring that every component of the system functions in harmony with your home's existing infrastructure. Unlike older units that were often oversized or poorly matched to ductwork, today’s standards require precision.
A professional installation begins with a complete assessment of your current setup. This involves checking the integrity of the existing ductwork to ensure it can handle the airflow requirements of a modern, high-efficiency unit. Leaky or undersized ducts can severely hamper the performance of a new system, leading to premature wear and higher energy bills. The service includes the safe removal and disposal of your old unit, adhering to all environmental regulations regarding refrigerant handling.
You can expect a full replacement of the critical components. This typically includes the outdoor condenser unit, the indoor evaporator coil, and the refrigerant line set if the existing lines are incompatible with the new coolant types. Additionally, the electrical disconnect box and whip—the wires connecting the unit to the power source—are often replaced to ensure safety and code compliance. The goal is to leave you with a system that turns on, cools down, and cycles efficiently from day one.

Replacing a central air conditioning system is a significant construction project that occurs within your home. To minimize disruption and ensure a flawless result, a structured workflow is essential. We utilize a methodical approach that prioritizes technical accuracy and property protection.
Before any equipment is ordered, a technician performs a load calculation. This is not a guess based on the size of the old unit. It is a calculation based on the square footage, insulation levels, window orientation, and local climate data for Greenville. This ensures the new unit is perfectly sized—neither too big (which causes short-cycling and humidity issues) nor too small (which causes the unit to run constantly without cooling).
Technicians arrive fully equipped to protect your property. Drop cloths are laid down to protect flooring in high-traffic areas. The area around the outdoor unit is cleared of debris, and the indoor workspace is prepped to allow safe access to the furnace or air handler.
The old system is disconnected from the electrical grid. Any remaining refrigerant is pumped down and reclaimed into recovery cylinders to prevent atmospheric venting. The old condenser and coil are physically removed from the property.
The new outdoor pad is leveled to ensure proper drainage and compressor operation. The new condenser is set in place. Inside, the new evaporator coil is installed on top of the furnace. The copper refrigerant lines are brazed together using nitrogen purging, a technique that prevents oxidation inside the pipes, which could otherwise clog the new system’s sensitive valves.
Once connected, a vacuum pump is used to remove all moisture and air from the lines, measured in microns. This step is critical; any moisture left in the lines can turn into acid and destroy the compressor. After achieving a deep vacuum, the factory-specified amount of refrigerant is released into the system.
The system is powered on and tested. Technicians measure static pressure, airflow, and temperature splits (the difference in temperature between supply and return air) to verify the system is performing to manufacturer specifications. All safety controls are verified.
Homeowners often struggle with the decision of whether to pour more money into an aging unit or to invest in a new system. While repairs can offer a short-term fix, there is a tipping point where replacement becomes the more financially sound option. Making this decision requires looking at the age of the unit, the cost of the repair, and the future reliability of the system.
Allegiance Heating & Air, LLC. often advises customers to utilize the "50% Rule." If the cost of the repair approaches 50% of the value of a new system, and the current unit is out of warranty, replacement is generally the wiser choice. Spending thousands on a compressor for a 12-year-old unit is rarely a good investment, as other components are likely to fail soon after.
Installing air conditioning in Greenville requires specific attention to the local climate and regulatory environment. The humid continental climate means that summers are not just hot but also laden with moisture. An air conditioner in this region must do two things: lower the temperature and remove humidity.
The longevity and efficiency of an air conditioner are determined more by the quality of the installation than the brand name on the metal box. A top-tier unit installed poorly will fail sooner and run less efficiently than a mid-range unit installed perfectly. The difference lies in the technical details: the quality of the brazing, the precision of the refrigerant charge, and the proper sealing of the ductwork.
Improper installation can reduce system efficiency by up to 30%. This not only impacts your monthly utility bills but also shortens the life of the compressor. By choosing a professional service that adheres to strict industry standards, you ensure that the equipment performs exactly as the manufacturer intended. This includes verifying that the airflow across the evaporator coil is correct—a step often skipped by budget installers but essential for preventing the coil from freezing up.
Furthermore, professional installation guarantees that your manufacturer’s warranty remains valid. Most manufacturers require proof of installation by a licensed contractor to honor parts warranties. Without this validation, you could be liable for expensive replacement parts if a component fails prematurely.
Once your new system is installed, maintaining it is key to protecting your investment. The first year of operation is the most critical for establishing a baseline of performance. Modern systems are designed to run for extended periods at lower speeds (if multi-stage) to maximize efficiency and comfort.
A broken air conditioner in the middle of a heatwave is an emergency that requires a swift and professional response. You need a partner who understands the urgency of the situation and possesses the technical expertise to resolve it correctly the first time. From accurate load calculations to the final testing of the system, every step of the process is designed to optimize your home’s cooling performance and energy efficiency.
