AC & Coil Systems

An AC and coil system is a specific type of split system configuration designed for homes that already have a functioning furnace. This combination includes the outdoor air conditioner unit and the indoor evaporator coil that sits on top of your furnace. Unlike a full system that includes a new blower, an AC and coil setup utilizes your existing furnace's fan to circulate the cooled air throughout your home.

Sizing for an AC and coil system is measured in tons or BTUs and should be based on a professional load calculation of your home. Factors such as square footage, insulation levels, and the number of windows all play a role in determining the right capacity. For most residential applications, systems range from 1.5 tons up to 5 tons. It is vital to match the tonnage of your new coil to the tonnage of your outdoor unit to ensure they operate in perfect synchronization.

Yes, you can certainly pair a new AC and coil combination with an existing gas or electric furnace. This is a common solution for homeowners whose air conditioning has failed but whose furnace still has years of reliable life left. However, you must ensure that your furnace’s blower motor is powerful enough to handle the airflow requirements of the new high-efficiency coil to prevent the system from freezing up.

Goodman offers a 10-Year Parts Limited Warranty on most AC and coil systems, provided the units are installed by a qualified professional and registered online within 60 days of the installation. This coverage applies to both the outdoor compressor and the indoor evaporator coil. Having a matched system from a single manufacturer simplifies the warranty process and ensures that all core cooling components are protected for a full decade.

Replacing your outdoor condenser and indoor Goodman evaporator coil as a matched set is the only way to ensure the system reaches its full SEER2 efficiency potential. Mixing a new high efficiency outdoor unit with an older indoor coil can lead to mismatched pressures and poor humidity removal. By installing a complete AC and coil system, you guarantee that all components are engineered to work together, which reduces strain on the compressor and lowers your monthly energy costs.

Yes, every AC and coil system we offer at HVAC Total is designed to meet or exceed the latest federal SEER2 requirements. These standards were established to ensure that all new residential cooling equipment operates at a higher level of efficiency than older models. By choosing a modern Goodman split system, you are investing in technology that uses less electricity to provide the same amount of cooling, which is better for the environment and your household budget.
