Air Conditioner & Air Handler Systems

An AC unit with air handler is a classic "split system" used to provide climate control for homes that typically do not utilize a gas furnace. This setup consists of an outdoor air conditioner condenser and an indoor air handler. While the outdoor unit is responsible for the cooling process, the air handler contains the blower motor that circulates conditioned air through your ductwork. For winter comfort, these systems are often equipped with electric heat kits to provide warmth.

The primary difference lies in how they create heat. A furnace burns fuel, such as natural gas or propane, to generate warmth. In comparison, an air handler is an electric-based unit. While it primarily houses the evaporator coil for cooling, it relies on electric resistance "heat strips" to provide heating. Because it does not involve combustion, an air handler does not require gas lines or flue venting, making it a popular choice for all-electric homes.

In alignment with the latest environmental standards, most new split system equipment is transitioning to R-32 refrigerant. R-32 offers superior energy efficiency and a significantly lower environmental impact compared to older refrigerants. While some R-410A units may still be available for specific replacement needs, the industry is moving toward R-32 to ensure compliance with modern efficiency regulations. We recommend confirming the refrigerant type on the product specifications page before your purchase.

A split system consists of two separate components: an indoor unit (the air handler) and an outdoor unit (the condenser). This is the most common residential configuration as it protects sensitive indoor components from the elements. A packaged unit, however, houses all cooling and heating components in one large outdoor cabinet, typically installed on a roof or a ground-level slab. Split systems are generally preferred for their higher efficiency ratings and longer lifespan.

Yes. As your system cools your home, it removes moisture from the air, which condenses into water on the evaporator coil. This water is collected in a primary drain pan located inside the air handler. To prevent water damage to your home, a dedicated PVC drain line must be installed to lead this water outside. We strongly recommend installing a secondary safety "float switch" that will automatically shut off the system if the drain line ever becomes clogged.

To keep your air handler running efficiently, you should inspect your air filter once a month and replace it at least every 90 days. In homes with pets or high levels of dust, monthly changes may be necessary. A clean filter ensures proper airflow, which prevents the coil from freezing and protects the blower motor from premature wear, helping your system last for many years to come.
