Installing a ductless heating and cooling system is a great step toward creating a healthier, more energy-efficient living environment for your family. While dustless systems have seen an upswing in popularity the last few years, they have actually been available for the last couple of decades. More homeowners are considering going ductless than ever before, largely due to the tax incentives for upgrading your home's existing system to a more energy-efficient option.
How ductless systems work
Ductless heat pumps work much like your current heat pump system, and can be easily installed by an HVAC specialist in a day or two. A unit installed outside of your home draws electricity that it uses to transfer heat between the outdoor unit and a smaller indoor unit. The indoor units can be recessed ceiling units or wall mounted units that are placed near the ceiling.
A three-inch hole is drilled in the exterior wall, and an outdoor conduit is run from the outdoor unit to the indoor unit. The outdoor conduit is typically available in a color to match your home's exterior for aesthetic purposes. Your contractor will determine how many indoor units you need, and most units have a swing vane that moves air into the far corners of the room.
Should you remove your old HVAC system?
Most experts suggest that you do not remove your home's ductwork or current HVAC system. The reason for this is that Atlanta is prone to extreme heat, and has fairly cold spells in the winter. During these times, you may find that your home is more comfortable with a little extra push from the backup system, similar to how you might add a ceiling fan to aid a traditional air conditioning unit.
Benefits of going ductless
The newest technology for ductless heating and cooling systems allows you to control the temperature of your home from a remote control, smart phone, computer or tablet. Most have state-of-the-art filters that only have to be washed instead of replaced, allowing for one filter to be effective for up to ten years.
Studies have shown that a properly installed ductless heating and cooling system can cut heating and cooling costs by as much as 50 percent. There are also tax benefits to upgrading your system. If you decide to go ductless, be sure to contact your electric and gas company. Many are offering rebates for homeowners who install ductless systems.
