Professional AC Installation in Gretna, LA

Your AC system has reached the end of its service life in Gretna. Or it failed and repair costs relative to its age make replacement the better decision in Gretna, LA. Or you are adding central cooling to a home that has not had it and you are ready to stop managing summer heat with window units in Gretna. Whatever the specific situation, you are making a significant investment in home comfort and energy efficiency that will affect your home for the next 15 to 20 years in Gretna, LA. And the two decisions that will determine whether that investment performs as you expect are the sizing decision and the installation quality in Gretna. Both matter more than the brand of equipment on the equipment pad in Gretna, LA.

A high-efficiency AC system installed with an incorrect refrigerant charge performs at significantly reduced efficiency in Gretna, LA. A system installed on a duct system with significant leakage delivers a fraction of its rated cooling capacity to the living spaces in Gretna. A system that is physically installed correctly but sized incorrectly for the home's actual cooling load operates in a mode that produces either persistent humidity problems or inadequate cooling capacity regardless of the efficiency rating on the equipment label in Gretna, LA. The equipment's rated efficiency is the efficiency it achieves under laboratory conditions. What you actually experience in your home is the efficiency the installation produces in Gretna.

Air America installs AC systems throughout Gretna, LA in Gretna. Correct sizing through load calculation before any equipment is selected in Gretna, LA. Correct installation of every system component in Gretna. Refrigerant charge verified to manufacturer specification before the system is commissioned in Gretna, LA. System performance verified before we leave in Gretna. Full permit management. And a guarantee on every installation in Gretna, LA. Call now, we respond fast in Gretna.

Why Installation Quality Determines System Performance in Gretna, LA

A central AC system has a rated SEER efficiency that represents its performance under standardized test conditions in Gretna. In a real residential installation, the actual efficiency the system achieves depends on correct refrigerant charge, correct airflow through the indoor coil, the condition of the duct system the system is installed on, and correct sizing for the specific home in Gretna, LA. An installation that misses on any of these variables produces a system that underperforms its rating in Gretna. An installation that gets all of them right produces the efficiency you are paying for in Gretna, LA.

Why Sizing Is the Most Important Decision

Why Correct AC Sizing Is the Most Important Installation Decision in Gretna, LA

What an Oversized AC System Does in Gretna

An oversized AC system cools the thermostat location to setpoint before the rest of the home has reached the same temperature in Gretna, LA. The system shuts off having satisfied the thermostat but having run for too short a cycle to remove adequate humidity from the circulated air in Gretna. The result is a home that feels cold and clammy rather than cool and comfortable in Gretna, LA. Indoor relative humidity remains elevated despite the air conditioner running in Gretna. Mold growth on surfaces throughout the home is more common in homes with oversized AC systems than in correctly sized homes in Gretna, LA. And the short cycling produces wear on the compressor at an accelerated rate in Gretna.

What an Undersized AC System Does in Gretna, LA

An undersized AC system runs continuously in hot weather without reaching the thermostat setpoint in Gretna. The home is consistently warmer than the thermostat calls for in Gretna, LA. The system runs at maximum capacity for extended periods, accumulating wear faster than a correctly sized system in Gretna. Energy bills are high because the system is running more hours per day than a correctly sized system would need to in Gretna, LA. And occupant comfort is poor because the home never reaches the set temperature in the hottest weather when cooling is most needed in Gretna.

How Air America Sizes Every AC Installation Correctly in Gretna, LA

Air America performs a Manual J load calculation for every AC installation in Gretna. The calculation accounts for every variable that affects the home's actual cooling load including floor area, ceiling height, insulation R-values in all building assemblies, window area and SHGC, local design temperature, and internal heat gains from occupants and appliances in Gretna, LA. The calculation output is the correct system capacity for the specific home in Gretna. Not an estimate based on square footage alone. A full load calculation in Gretna, LA.

Why Manual J Is the Only Correct Sizing Method in Gretna, LA

The rule of thumb sizing method of one ton of cooling per 500 to 600 square feet of floor area produces wildly inaccurate results for homes that deviate from the assumptions embedded in that rule in Gretna. A well-insulated home with efficient windows may need significantly less cooling capacity per square foot than the rule assumes in Gretna, LA. A home with large south-facing windows, high ceilings, and minimal insulation may need significantly more in Gretna. Manual J accounts for all of these variables and produces the correct capacity for the specific home rather than an estimate for an average home of that size in Gretna, LA.

Replacing Old vs Installing New

Replacing an Old AC vs Installing New in Gretna, LA

Signs Your Existing AC System Should Be Replaced in Gretna

An AC system approaching or past its 15-year service life that requires a major repair warrants a replacement comparison in Gretna, LA. A system that has required multiple repairs in recent seasons is communicating that its remaining service life is limited in Gretna. A system using R-22 refrigerant that has phased out of production faces increasingly expensive refrigerant costs for any refrigerant-related repair in Gretna, LA. And a system that is significantly less efficient than current equipment is costing the homeowner measurably more in energy every year it continues to operate in Gretna.

The Efficiency and Comfort Gains From a New Correctly Sized System in Gretna, LA

A new high-efficiency AC system replacing a 15-year-old standard efficiency system can reduce cooling energy consumption by 30 to 50 percent depending on the efficiency ratings being compared in Gretna. A correctly sized replacement system eliminates the short cycling humidity problems that an oversized original installation may have been producing in Gretna, LA. And a variable speed replacement system produces a level of indoor comfort and humidity control that single-stage systems cannot match in Gretna.

FAQ

AC Installation FAQs in Gretna, LA

The correct system size is determined by a Manual J load calculation that accounts for your home's floor area, insulation levels, window area and orientation, local climate data, and home configuration in Gretna. Square footage rules of thumb produce inaccurate results for homes that deviate from average construction characteristics in Gretna, LA. Air America performs a Manual J calculation for every AC installation in Gretna.
Manual J is the industry-standard method for calculating a home's actual heating and cooling load developed by the Air Conditioning Contractors of America in Gretna. It accounts for every variable that affects the home's thermal performance including insulation, window performance, orientation, internal heat gains, and local climate data in Gretna, LA. It produces the correct system capacity for the specific home rather than a general estimate in Gretna.
A standard central split system AC replacement typically takes four to eight hours in Gretna. A new installation in a home without existing equipment takes longer because of the additional work involved in installing line sets, electrical supply, and condensate drainage in Gretna, LA. Ductless mini-split installations vary based on the number of zones in Gretna.
If both systems are near the end of their service lives, replacing both at the same time typically makes sense because it allows the systems to be correctly matched to each other, produces a single installation visit cost, and starts both systems on the same replacement timeline in Gretna. Air America provides a clear assessment of both systems' condition to help the homeowner make this decision in Gretna, LA.
The correct SEER selection depends on how many hours per year the system will be used, local electricity rates, and the premium cost of higher efficiency equipment relative to the energy savings it produces in Gretna. In climates with long cooling seasons and high electricity rates, higher SEER systems produce faster payback in Gretna, LA. Air America provides a payback calculation for each efficiency option in Gretna.
Yes in most jurisdictions in Gretna. HVAC installation is a regulated trade that requires permits and inspection in most areas in Gretna, LA. Air America manages the permit application and final inspection for every AC installation in Gretna.
A complete Air America AC installation includes load calculation and system sizing, equipment selection and ordering, removal of the existing system where applicable, installation of the new outdoor condenser, indoor coil, refrigerant line set, electrical supply connections, condensate drainage, refrigerant charge verification, system commissioning and performance verification, and permit management in Gretna.
A correctly sized and correctly installed residential AC system has a designed service life of 15 to 20 years in most climates in Gretna. Systems that are correctly maintained through annual service, regular filter replacement, and prompt attention to developing faults typically reach or exceed the upper end of that range in Gretna, LA.
In many cases yes, but the existing ductwork should be assessed for leakage, correct sizing for the new system's airflow requirements, and physical condition before the new system is installed in Gretna. Significant duct leakage reduces the performance of any AC system installed on it in Gretna, LA. Air America assesses the existing ductwork as part of every replacement installation in Gretna.
An overcharged system produces elevated head pressure that stresses the compressor and reduces efficiency in Gretna. An undercharged system reduces cooling capacity and may cause the evaporator coil to freeze in Gretna, LA. Both conditions reduce the system's efficiency rating significantly below what the equipment is rated for and accelerate compressor wear in Gretna. Air America verifies the refrigerant charge to manufacturer specification on every installation in Gretna, LA.
AC installation costs in Gretna range from $3,500 to $5,500 for standard efficiency central systems in smaller homes, $4,500 to $7,000 for larger homes, $5,500 to $9,000 for high-efficiency systems, and $6,000 to $10,000 and above for variable speed heat pump systems in Gretna, LA. All pricing confirmed before any equipment is ordered in Gretna.
Yes. Every Air America AC installation is guaranteed in Gretna. If the installation does not perform as specified within the guarantee period, we return and address it at no additional charge in Gretna, LA.
