Efficient HVAC Solutions to Tackle Any Season

Living in this region means dealing with a humid subtropical climate where weather patterns swing drastically between seasons. Your home requires a system capable of handling high humidity levels in July and freezing temperatures in January. An undersized or outdated unit will struggle to maintain set temperatures, leading to continuous running cycles, increased wear and tear, and skyrocketing utility costs.

We provide comprehensive installation services for a variety of systems designed to meet these specific environmental demands. Whether you require a traditional split system, a packaged unit, or a high-efficiency heat pump, the goal is ensuring the equipment matches the thermal load of your property. Proper sizing is critical; a unit that is too large will short-cycle and fail to dehumidify the air, while a unit that is too small will run indefinitely without reaching the desired temperature.

Modern HVAC technology offers significant improvements over models manufactured just a decade ago. New systems utilize advanced refrigerants and variable-speed blowers to modulate airflow, providing precise comfort control. By upgrading your infrastructure, you gain better control over indoor air quality and humidity, which is a primary concern for homeowners in Louisville and the surrounding areas.

What Our HVAC Service Includes—Today and Beyond

When you schedule a replacement or new installation, you are purchasing more than just a piece of machinery; you are investing in a complete climate solution — schedule service today. Our service is designed to be turnkey, managing every aspect of the project from the initial calculation to the final safety check:

Comprehensive Site Evaluation

Every installation begins with a detailed load calculation. We do not simply swap out the old unit for a machine of the same size. Home renovations, window upgrades, or changes in insulation can alter the heating and cooling requirements of a structure:

  • Measurement of square footage and window orientation.
  • Assessment of insulation levels in attics and crawl spaces.
  • Inspection of current ductwork integrity and airflow capacity.
  • Calculation of Manual J requirements to ensure precise equipment sizing.

System Removal and Disposal

Replacing an HVAC system involves handling heavy equipment and regulated materials. We manage the safe disconnection of gas lines, electrical circuits, and refrigerant lines:

  • Safe recovery of old refrigerant in compliance with EPA regulations.
  • Removal of the existing furnace, air handler, and outdoor condenser.
  • Environmentally responsible disposal or recycling of old metal and components.
  • Cleaning of the installation area to prepare for the new unit.

Precision Installation

The longevity of your system depends heavily on the quality of the installation. Even the highest-rated equipment will fail prematurely if installed incorrectly:

  • Leveling and stabilization of the outdoor condenser pad.
  • Fabrication of custom sheet metal transitions to connect the new unit to existing ductwork.
  • Brazing of copper refrigerant lines using nitrogen purging to prevent oxidation.
  • Installation of new condensate drain lines and safety switches to prevent water damage.

Understanding the Installation Process: What to Expect

Knowing the specific steps of an installation helps homeowners prepare for the service day. A standard replacement typically takes one day, though complex setups or major ductwork modifications may extend the timeline, request a quote for complex setups. The process is systematic, prioritizing safety and property protection.

Preparation and Safety Setup

Technicians arrive with the necessary equipment and protective gear. The first priority is protecting your home flooring and clearing a path to the service areas:

  • Laying down drop cloths and protective floor coverings.
  • Shutting off power and gas supplies to the HVAC equipment.
  • Verifying that the workspace is clear of debris and obstacles.

Equipment Placement and Connection

Once the old unit is removed, the new system is positioned. This phase requires technical expertise to ensure all connections are secure and code-compliant:

  • Positioning the indoor evaporator coil and furnace/air handler.
  • Connecting the flue pipe for gas furnaces to ensure proper venting of carbon monoxide.
  • Wiring the high-voltage electrical connections and low-voltage thermostat controls.
  • Connecting gas lines and testing for leaks using electronic detectors.

System Charging and Calibration

After physical connections are made, the system must be charged with refrigerant and calibrated for the specific home environment:

  • Evacuating the refrigerant lines with a vacuum pump to remove moisture and air.
  • Weighing in the precise amount of refrigerant required by the manufacturer.
  • Adjusting blower speeds to match the static pressure of the ductwork.
  • Testing the thermostat to ensure it communicates correctly with the new equipment.

Final Commissioning

The job is not complete until the system is running at peak efficiency. This final audit verifies performance metrics against factory specifications:

  • Measuring temperature differentials (delta T) across the coil.
  • Verifying voltage and amperage draws on motors and compressors.
  • checking all safety limits and shut-off switches.
  • Walking the homeowner through the new thermostat operation and filter maintenance.

Deciding Between Repair and Replacement: What's Best for You

Homeowners often struggle to determine if a malfunction warrants a simple repair or a full system replacement. Making the right financial decision involves analyzing the age of the unit, the cost of the repair, and future efficiency gains:

The 50% Rule

A common industry standard for making this decision is the 50% rule. If the cost of the repair approaches 50% of the value of the system, or 50% of the cost of a new unit, replacement is generally the smarter financial move. Investing heavy capital into a dying system often leads to throwing good money after bad.

Age and Reliability

HVAC systems typically last between 10 and 15 years depending on maintenance history and usage intensity:

  • If a heat pump or air conditioner is over 10 years old and requires a major component like a compressor, replacement is recommended.
  • Furnaces over 15 years old with cracked heat exchangers pose safety risks and should be replaced immediately.
  • Frequent breakdowns that require multiple service calls in a single season indicate the system has reached the end of its reliable lifespan.

Efficiency Considerations

Older units often operate at significantly lower efficiency levels compared to modern standards:

  • A 15-year-old AC unit may operate at 8 or 10 SEER, whereas modern units start at 14 SEER2 and go much higher.
  • Replacing an 80% AFUE furnace with a 96% AFUE model means 16% less natural gas is wasted, resulting in immediate monthly savings.
  • New systems often qualify for tax credits or utility rebates that can offset the initial installation cost.

Comfort and Air Quality Issues

Sometimes a unit runs but fails to provide comfort. If your home has hot and cold spots, excessive dust, or humidity issues that the current system cannot resolve, a replacement with modern zoning or variable-speed technology offers a solution that repairs cannot achieve. Allegiance Heating & Air, LLC. can assess your current comfort levels to recommend the appropriate upgrade.

Louisville Regulations and Seasonal Considerations for HVAC

Local regulations and climate factors play a massive role in how HVAC installations are planned and executed. Compliance with these rules ensures the safety of your home and the validity of your insurance coverage.

Permitting and Code Compliance

In this area, HVAC replacements and new installations require permits from local building departments. This oversight ensures that the work meets safety standards regarding electrical wiring, gas piping, and venting:

  • Permits must be pulled before work begins.
  • A third-party inspection is often required after installation to verify code compliance.
  • Non-compliant installations can cause issues when selling a home or filing insurance claims for fire or water damage.

Utility Requirements

Local utility providers often have specific requirements for equipment connection and efficiency:

  • Electrical disconnects must be located within sight of the outdoor unit for safety.
  • Gas lines must have a sediment trap (drip leg) installed to protect the gas valve from debris.
  • High-efficiency units may require specific venting materials (PVC vs. metal) to handle acidic condensate.

Seasonal Timing for Installation

While breakdowns often force immediate replacement, planning an installation during shoulder seasons (spring and fall) can be beneficial:

  • Spring: Installing cooling equipment before the humidity spikes ensures you are ready for the first heatwave.
  • Fall: Replacing a furnace before the first freeze guarantees reliable heating and prevents frozen pipes.
  • Winter/Summer: Emergency replacements are available, but demand is higher. Proactive replacement allows for more flexible scheduling.

Local Climate Impact on Equipment

The local humidity levels require specific attention to moisture removal:

  • Variable-speed air handlers are highly recommended for this region as they run longer cycles at lower speeds, removing more moisture from the air than single-stage units.
  • Heat pumps are an effective solution here, but they often require a dual-fuel setup (hybrid heat) with a gas furnace to handle the coldest nights of the year effectively.

Why Choose Us? Local Expertise and Reliable Service

Selecting the right contractor is just as important as selecting the right brand of equipment. An improper installation can reduce the efficiency of a high-end unit by up to 30%. We focus on technical precision and customer transparency to deliver lasting results:

  • Licensed and Insured: We carry all necessary state licenses and liability insurance to protect your property and our technicians.
