If your current air conditioner in Atlanta, Alpharetta, Marietta or a surrounding area is more than 12 years old, struggles to keep your home cool during summer, or requires frequent repairs, you are likely past the point where repair makes financial sense. A properly installed AC system will cool your home evenly, run quietly, and use significantly less energy than an older unit that was never sized correctly for your square footage. WS Maintenance Service Company - Heating and Air Pros handles new system installations and full replacements across Atlanta with a focus on proper sizing, seamless integration with your ductwork, and post-installation testing.


This service includes removal and disposal of your old equipment, professional installation of a new system matched to your home's cooling load, and high-efficiency unit options that reduce monthly energy costs. You also receive updated airflow design if your existing ductwork is undersized or poorly configured.

How AC Installation is Done Correctly

When you schedule AC installation in Atlanta and surrounding areas, the process begins with a cooling load calculation that accounts for your home's square footage, insulation levels, window placement, and how many people live there. This ensures the new system is not oversized, which would cause short cycling and humidity problems, or undersized, which would leave your home warm during peak summer months. The old unit is disconnected, refrigerant is recovered, and the equipment is hauled away as part of the installation.


After installation is complete, your home will cool faster and more evenly, your thermostat will maintain the set temperature without constant adjustments, and your monthly energy bill will drop if your previous system was inefficient or oversized. You will also notice quieter operation and better humidity control on humid Georgia days.


The installation includes connecting the new system to your existing ductwork or updating airflow design if needed, running new refrigerant lines, installing a programmable thermostat if requested, and testing the system under full load. This service does not include structural modifications to your home or installation of systems in commercial buildings.

You Probably Have a Few Questions First

Before committing to a new AC installation in Atlanta, homeowners typically want to know how long the work will take, whether their ductwork can be reused, and what efficiency ratings actually mean for their monthly bill.

How long does AC installation take?
Most AC installations in Atlanta take one full day for a straightforward replacement and up to two days if ductwork modifications or electrical upgrades are needed. You will have cooling restored by the end of the work day.
What does proper system sizing mean?
Proper sizing means the system matches your home's cooling load based on square footage, insulation, and heat gain. An oversized system will cycle on and off too frequently, while an undersized system will run constantly and still fail to cool your home.
Can I reuse my existing ductwork?
Most existing ductwork can be reused if it is in good condition and properly sized for the new system. If your ducts are undersized, leaking, or poorly designed, they may need to be sealed or replaced to support efficient airflow.
What is a SEER rating?
SEER stands for Seasonal Energy Efficiency Ratio and measures how efficiently an AC system cools your home. Higher SEER ratings mean lower energy consumption, which translates to reduced monthly utility bills in Georgia's hot climate.
What happens to my old AC unit?
Your old unit is disconnected, the refrigerant is recovered according to EPA regulations, and the equipment is removed and disposed of properly. You do not need to arrange for hauling or recycling.
