Comprehensive HVAC Installation Solutions

When you invest in a new heating and cooling system, you are purchasing more than just the equipment; you are paying for the expertise required to design, size, and install that equipment correctly. A high-performance unit installed poorly will operate like a low-end unit, consuming more energy and failing prematurely.

Our installation service covers every technical aspect required to bring your home up to modern cooling and heating standards. We handle the complete removal and environmentally safe disposal of your existing unit. This includes recovering old refrigerant according to EPA standards so that no harmful chemicals are released into the atmosphere.

The core of our service involves the precise installation of the condenser (outdoor unit) and the evaporator coil or air handler (indoor unit). We ensure the refrigerant lines are brazed with nitrogen to prevent oxidation, a critical step that many budget installers skip but is essential for the long-term health of your compressor. We also transition your electrical connections, install a new disconnect box if necessary, and upgrade the thermostat to a compatible, programmable, or smart model that helps manage humidity levels common in Louisiana.

We verify that your ductwork is compatible with the new system's airflow requirements. If the static pressure is too high, it can choke the new system. Our technicians assess the supply and return plenums to guarantee balanced air distribution throughout your property.

How the Installation Process Works

Replacing a central air system is a major construction project within your home, but we structure the process to be as non-intrusive and efficient as possible. We follow a strict protocol to ensure nothing is missed and your home remains clean throughout the job.

• Site Evaluation and Load Calculation: First, we perform a Manual J load calculation. We do not simply read the size off your old unit and replace it with the same size. Home renovations, new windows, or insulation changes can alter your heating and cooling load. We measure square footage, window orientation, and insulation levels to determine the exact BTU capacity required for your specific layout.
• System Selection and Design: Based on the load calculation, we present options ranging from single-stage standard efficiency units to variable-speed high-efficiency systems. We discuss SEER2 ratings and how they impact your monthly utility costs. Once a system is selected, we plan the modification of the transition ductwork and the placement of the outdoor pad to ensure level operation.
• Safe Removal and Site Preparation: Technicians arrive with drop cloths and floor protection. We shut off power and gas lines safely. The old equipment is disconnected, and the refrigerant is recovered. We then remove the bulky equipment from the attic, closet, or crawl space carefully to avoid damaging walls or flooring.
• Equipment Installation and Connection: The new indoor and outdoor units are set in place. We connect the line set (copper tubing), ensuring it is properly insulated to prevent sweating and water damage. We connect the high-voltage electrical wiring and the low-voltage control wiring. A new filter drier is installed to trap moisture and debris within the refrigerant system.
• Vacuum and Charging: Before releasing the refrigerant, we pull a deep vacuum on the lines to remove all oxygen and moisture. This is verified with a micron gauge. Once the system is dry and tight, we release the factory charge and fine-tune it using subcooling and superheat methods to match the manufacturer’s specifications exactly.
• Testing and Walkthrough: The system is powered on and tested in all modes. We measure temperature splits (the difference between air entering and leaving the unit) to confirm performance. Finally, we walk you through the operation of your new thermostat and explain maintenance requirements, such as filter changes and drain line cleaning.

When to Replace vs. Repair Your System

Deciding between another repair bill and a full system replacement is a financial calculation. While repairs are cheaper in the short term, an aging system is a liability that often costs more to operate and maintain than a new system costs to finance.

You should opt for replacement if your system uses R-22 refrigerant. This coolant has been phased out, making it strictly limited and incredibly expensive to source. If an R-22 system develops a leak, the cost of the refrigerant alone often exceeds the value of the unit. Investing in a new system that uses R-410A or newer refrigerants is the only economically viable choice. — view current promotions

Consider the "50% Rule." If the cost of the repair is 50% or more of the cost of a new system, replacement is the smarter financial move. Furthermore, if your heat pump or air conditioner is over 10 to 12 years old and requires a major repair—such as a compressor or blower motor—the remaining lifespan of the unit does not justify the expense.

Frequency of breakdown is another key indicator. If you have required repairs more than twice in the last two years, your system is unreliable. In the humid climate of Mathews, an unreliable system is a health risk due to the potential for mold growth when humidity is not controlled. Martin's Heating & Air Conditioning can evaluate your repair history and provide a cost-benefit analysis to help you make the right decision.

Energy bills that have steadily increased over the last few years suggest the system is losing efficiency. Components wear out, coils corrode, and motors experience higher friction, all of which draw more amps to do the same amount of work. A modern system can cut cooling costs by 20% to 40% immediately upon installation.

Local Considerations for Mathews Residents

Installing HVAC equipment in our region requires specific attention to environmental factors that off-the-shelf advice often misses. The high humidity levels here mean that sizing is critical. If a unit is oversized, it will cool the house too quickly and shut off before it has removed the humidity. This results in a "clammy" cold feeling and potential mold issues. We size units to have long, steady run times that effectively dehumidify the air.

• Permitting and Code Compliance: Installation involves electrical and mechanical work that must adhere to local building codes. We handle the acquisition of necessary permits required by the parish or municipality. This ensures that your installation is legal, safe, and will not cause issues if you ever decide to sell your home.
• Hurricane and Storm Security: Outdoor units in our area are vulnerable to high winds and storm debris. We use specific tie-down methods and heavy-duty hurricane pads to secure the condenser unit. This prevents the unit from shifting or tipping during severe weather, protecting the copper lines from snapping.
• Corrosion Protection: Salt air and high humidity can accelerate corrosion on standard aluminum coils. We offer equipment options with epoxy-coated coils or all-aluminum construction that resist corrosion better than older copper-tube-aluminum-fin designs. This extends the life of the unit and prevents refrigerant leaks caused by oxidation.
• Heating During Cold Snaps: While cooling is the priority, our winters do see temperatures drop into the 30s. Heat pumps are the most efficient solution for this climate. They move heat rather than creating it. However, we also ensure properly sized electric heat strips are installed as an auxiliary heat source (emergency heat) to keep your home warm during those few days when temperatures freeze.

Why Professional Installation Matters

The longevity of your HVAC system is determined 80% by the quality of the installation and 20% by the brand of the equipment. A top-tier brand installed without proper evacuation, airflow balancing, or electrical safety measures will fail years before its expected lifespan.

We focus on the details that impact longevity. This includes using nitrogen during brazing to keep lines clean, ensuring the unit is perfectly level for proper oil return to the compressor, and sealing all duct connections with mastic to prevent air loss. We do not cut corners on materials; we use high-quality insulation, copper, and electrical components.

Your safety is paramount. HVAC systems involve high-voltage electricity and, in some cases, natural gas or propane. Improper installation can lead to fire hazards, carbon monoxide leaks, or electrical shorts. Our technicians are trained to adhere to strict safety protocols, ensuring the protection of your family and property.

We also respect your property. The installation area is left cleaner than we found it. All debris, packaging, and old equipment are hauled away. You are left with a new, quiet, efficient system and no mess.
