When you invest in a new system, the following components and services are standard:

• Complete System Removal and Disposal: We safely disconnect and remove your existing cooling unit, including the outdoor condenser and the indoor evaporator coil. We handle the environmentally safe disposal of old refrigerants and scrap metal, keeping your property clean and compliant with environmental regulations.
• Manual J Load Calculation: Guesswork leads to inefficiency. We perform a precise calculation to determine the exact cooling load required for your home. This ensures the unit is neither undersized (which causes it to run constantly) nor oversized (which leads to short cycling and poor humidity control).
• Equipment Placement and leveling: The longevity of a condenser depends on a stable foundation. We install a new composite pad if necessary and ensure the unit is perfectly level to facilitate proper oil return to the compressor and correct drainage.
• Line Set Management: We inspect existing refrigerant lines. If they are compatible and in good condition, we flush them thoroughly. If not, we install new copper line sets to ensure no contaminants compromise the new compressor.
• Electrical Safety Inspection: Our technicians verify that your existing electrical service, disconnect box, and wiring gauge can safely handle the amperage of the new high-efficiency unit.
• Thermostat Integration: We install or calibrate your thermostat to communicate effectively with the new system. This often includes upgrading to smart thermostats that allow for humidity control and remote scheduling.

Our AC Installation Process: Quick and Clean

We have refined our installation procedures to be as non-intrusive as possible while maintaining strict technical standards. The goal is to get your system running at peak performance with minimal disruption to your daily routine. By following a strict protocol, we ensure that no step is missed and that every manufacturer specification is met.

• Site Preparation and Protection: Before any heavy lifting begins, our team prepares the workspace. We use drop cloths and shoe covers to protect your flooring and furniture. The area surrounding the indoor and outdoor units is cleared to ensure technicians have safe access without damaging your landscaping or interior belongings.
• System Decommissioning: Power is cut to the HVAC system to ensure safety. We then recover any remaining refrigerant from the old unit into certified recovery cylinders, preventing harmful chemicals from venting into the atmosphere.
• Ductwork and Plenum Inspection: Once the old unit is removed, we inspect the visible supply and return plenums. If there are air leaks or restrictions, we address them immediately. Connecting a new, high-efficiency AC to leaky ductwork significantly reduces the system's performance, so sealing these connections is a priority.
• Component Installation: The new evaporator coil is installed on top of the furnace or air handler, and the new condenser is positioned outside. We braze the copper refrigerant lines using a nitrogen purge. This critical step prevents oxidation inside the pipes, which can clog the sensitive metering devices of modern AC units.
• Vacuum and Charge: After brazing, we pull a deep vacuum on the system to remove all moisture and non-condensable gases. Moisture inside the lines is the enemy of an AC system, leading to acid formation and compressor failure. Once the vacuum is verified, we release the factory refrigerant charge and fine-tune it based on "subcooling" and "superheat" measurements specific to the day's weather conditions.
• Final Commissioning and Walkthrough: We do not leave until the system is cooling effectively. We check the temperature split between the supply and return air to verify capacity. Finally, we walk you through the operation of the new system, explaining filter changes, thermostat settings, and warranty registration.

Deciding Between AC Repair and Replacement

Determining whether to repair an aging unit or invest in a replacement is a significant financial decision for homeowners. While repairs can offer a short-term fix, there is a tipping point where continued investment in an old system becomes economically unwise. Understanding the variables involved helps you make a logical choice based on data rather than stress.

Consider replacement if you encounter the following scenarios:

• The 50% Rule: If the cost of the repair approaches 50% of the value of a new system, replacement is generally the smarter financial move. A major component failure, such as a blown compressor or a leaking coil out of warranty, often triggers this threshold.
• System Age: Most air conditioners have a lifespan of 10 to 15 years. If your unit is over 12 years old and requires a significant repair, investing that money into a new system resets your warranty clock and eliminates the risk of another breakdown next month.
• Rising Energy Bills: As AC units age, they lose efficiency due to wear and tear on the compressor and coil corrosion. If your summer electric bills are steadily climbing despite normal usage, your system is likely working overtime to provide the same amount of cooling. Modern SEER2-compliant units can drastically reduce monthly energy consumption.
• Frequent Breakdowns: If you have called for service multiple times in the last two seasons, your system is signaling the end of its reliable life. The cost of cumulative minor repairs often exceeds the monthly payment of a financed new installation.
• R-22 Freon Dependency: Older units utilize R-22 refrigerant, which has been phased out globally. Supplies are scarce and extremely expensive. If an older R-22 unit develops a leak, replacement is almost always the only viable option, as "topping it off" is cost-prohibitive.
• Uneven Comfort and Noise: An aging system often struggles to push air to the second floor or the far ends of the house. If you notice loud banging, grinding noises, or rooms that never get cool, the mechanical components are likely failing.

Allegiance Heating & Air, LLC assists in this evaluation process by providing transparent assessments of your current unit’s condition, allowing you to compare the cost of repair versus the long-term savings of replacement.

Louisville-Specific AC Installation Considerations

Installing air conditioning in this region requires specific attention to local climate patterns and regulations. A system that works well in an arid climate will struggle here. The local weather is characterized by high humidity, meaning your AC has two jobs: lowering the temperature and removing moisture from the air.

• Humidity Control is Critical: In our humid subtropical climate, sizing is everything. An oversized unit will cool the house too quickly and shut off before it has run long enough to dehumidify the air. This leads to a cold, clammy indoor environment and promotes mold growth in ductwork. We prioritize correct sizing to ensure long run times that effectively pull moisture out of the air.
• Variable Speed Technology: For the best comfort in this region, we often recommend two-stage or variable-speed compressors. These units can run at lower capacities on mild but humid days, maintaining comfort without consuming maximum energy. This technology is particularly effective at handling the fluctuation between our intense summer storms and oppressive heat waves.
• Electrical and Zoning Codes: Local building codes strictly dictate how disconnect boxes, wiring, and breaker panels must be configured for HVAC equipment. Compliance ensures safety and is required for future real estate transactions. We handle all necessary permitting and ensure that the installation meets the National Electric Code (NEC) as adopted by local authorities.
• Clearance and Airflow: Due to the lush vegetation common in the area, outdoor units must be placed where they have adequate clearance from shrubs, fences, and dryer vents. Cottonwood and pollen are prevalent here and can clog condenser coils rapidly. We select installation locations that minimize debris intake and allow for easy maintenance access.
• Rebate Availability: Local utility providers often offer rebate programs and tax credits available for homeowners who install high-SEER heat pumps or air conditioners, helping you maximize your return on investment.

Why Professional Installation Matters

The most important day in the life of your air conditioner is the day it is installed. Industry studies consistently show that improper installation can reduce system efficiency by up to 30% and significantly shorten equipment life. A high-quality brand installed poorly will perform worse than a budget brand installed perfectly.

Professional installation focuses on the invisible details that impact performance. This includes the precise level of refrigerant charge, the volume of airflow across the coil, and the integrity of the duct connections. When these elements are calibrated correctly, the equipment operates under less stress, consumes less electricity, and provides consistent comfort.

Furthermore, manufacturer warranties are almost universally contingent on proof of professional installation. Attempting DIY solutions or hiring unlicensed labor can void these warranties instantly, leaving you without protection if a component fails. Professional installers register your equipment, ensuring you receive the full benefit of parts and labor warranties.

Investing in professional service also guarantees that your home is respected. From the initial load calculation to the final explanation of your new thermostat, the process is designed to be transparent and educational. You receive documentation of all work performed, which serves as a valuable record for maintaining the value of your home.
