AC Installation Options for Every Home

Every home has unique needs, which is why we provide multiple installation options. From traditional central air systems to flexible ductless units, we help homeowners choose the solution that fits their space, lifestyle, and budget.

  • Central Air Systems: The most common option for Alabama homes, featuring an outdoor compressor, indoor unit, ductwork, and supply vents. Precise sizing is critical, since undersized units overwork and oversized units waste energy. We carefully match the system to your home’s square footage for reliable cooling.
  • Ductless Mini-Split Systems: Perfect for additions, renovations, or rooms without ductwork. These systems require only a small wall opening and provide targeted cooling. Multiple indoor units can be connected to one outdoor compressor, creating a flexible and efficient setup. Many homeowners see lower energy bills with ductless systems.
  • New Construction Installations: Building a new home provides the ideal opportunity to plan your comfort system from the ground up. Our team works with builders to install ductwork, compressors, and air conditioners that meet your home’s needs. We can also review ductless options to save space and improve efficiency.

Installation performed by an experienced team helps your system reach peak efficiency, improves airflow, and reduces repair costs over time. Our technicians take the time to install every unit with precision, so you get maximum performance and lasting comfort.

Frequently Asked Questions About AC Installation

If your system is more than 10–15 years old, breaks down frequently, or can’t keep your home comfortable, it may be time for a new AC installation. Rising energy bills and uneven cooling are also signs that your unit may no longer be efficient. Our technicians can assess your system and provide clear recommendations.

Homeowners can choose from several options:

  • Central air conditioning systems
  • Ductless mini-split systems
  • Energy-efficient models with advanced features
  • Systems designed for new construction projects

Each option has its advantages, and we help you decide which best fits your home’s layout and comfort needs.

Most installations are completed within a single day, depending on the size of the home and the complexity of the system. Ductless installations may be quicker, while new construction projects require additional planning. Our team works efficiently while maintaining a high standard of quality to set your system up for long-term value.

Zoning divides your home into separate comfort areas and makes your HVAC equipment cool or heat only areas that need conditioning.

For example, a living room with large windows may stay too hot in the summer and too cold in the winter. However, if your system is trying hard to keep that room comfortable, other rooms with less exposure may feel too warm or too cold by comparison.

A zoning system will send more conditioned air to the living room to make up for the heat gained or lost through the windows, without affecting other areas of the house. These sorts of zones can be configured for the unique structure and usage of your property.

New AC installation is a great opportunity to consider zoning your home for efficiency and cost savings!

Zoning helpfully caters to modern lifestyles and comfort needs. Maybe you have a home office that needs extra conditioning during the day and none at night. Or you only use the upstairs or back bedrooms when guests visit.

By zoning your home, you create distinct temperature areas, meaning the whole house doesn’t have to be the same temperature, and energy doesn’t have to be expended in unused rooms. This cuts down on energy consumption and can reduce your electrical bills as well as HVAC system repair needs!

Whatever your needs, zoning can keep each area of your house at the perfect temperature for you and your family members. Request an estimate on zoning when you contact Mainline about your AC installation.

System size is based on your home’s square footage, insulation, layout, and cooling needs:

  • A unit that is too small will struggle to maintain comfort
  • A unit that is too large will cycle too quickly, wasting energy
  • Appropriate sizing balances efficiency and comfort

Our technicians carefully calculate the right size before installation to match your home’s requirements.

​​A new air conditioner offers improved comfort, quieter operation, and lower energy bills. Modern systems provide advanced features like smart thermostats and variable speed technology. Most importantly, new equipment reduces the risk of breakdowns during the hottest months, giving you peace of mind that your home will stay cool and comfortable.
