A key point is that ductless systems are generally cheaper to run. Can concentrate cooling and have less efficiency loss due to duct problems. They also need much less maintenance over time. Ductless systems, also known as mini-split systems, are installed directly on the walls of your home.
They don't use ducts, which makes them less expensive to install in homes that don't yet have ducts, and they're more energy efficient because they don't lose energy as air travels, like central air conditioners do. Ductless units are more visible, as you see them on the wall, and to cool your entire home, you may need more than one. However, you can use them to cool specific parts of your home, or even use them together with central air to create separate zones for areas that aren't used as often or for areas that need additional cooling. If you already have ducts installed in your home, installing a central air conditioner is relatively simple.
The unit is placed on a concrete deck 1 outside and connects to existing ducts and the HVAC system. If you don't already have ducts installed, then getting central air conditioning can be a slow and difficult installation. This is because ducts must run throughout the house, from the air conditioner to every room. This involves making holes in walls, floors and ceilings, as well as passing the ducts themselves, often through areas such as attics and closets to disguise them.
The installation costs of the central air conditioning unit are usually more expensive than the installation without ducts. However, if your home is more than 2500 square feet, ductless systems will not be an effective system for you. In that case, choosing a central air conditioning unit will be the best option to meet your long-term heating and cooling needs. Central air conditioning can also withstand much colder temperatures compared to ductless mini-systems.
Ductless systems are more expensive than central air at the time of installation. However, due to their energy efficiency, they allow you to save money in the long run. Because ductless systems allow you the option of zoning, you have more control over how much energy is spent cooling each room. This can significantly reduce your utility bill over time compared to central air conditioning units.
Many homeowners will not need these additional indoor units if they have the ducting installed for a traditional HVAC system. However, there are homes without adequate ducts, and these homes usually do not have convenient areas in which ducting can be installed. In these situations, your only option might be a ductless system. If ductless systems cost more at first, it means that central air will be less expensive.
This will always be true in homes with existing ducts that do not need modifications for the installation of a new system. Duct network alone can sometimes exceed the cost of an air conditioner or oven, so in these cases, the initial cost may be similar for a ductless system. Whether you choose a split ductless or multisplit system, each ductless air conditioner will require a few steps to keep both components operating in optimal condition over their estimated 12-15 year lifespan. In most cases, adding any type of air conditioning to a home does not increase its market value, although in some climates not having air conditioning could make a home more difficult to sell.
However, after the heat waves of recent summers, air conditioning has gone from something pleasant to an essential one. You may have heard of ductless mini-splits and wondered about their cost, efficiency or utility compared to a traditional air conditioner or oven. If you already have forced hot air installed, the central air conditioner can use the same ducts, or new ducts can be added only for the purpose of delivering the cold air. The main difference between ductless mini split air conditioning units and central air conditioning systems is the way treated air is distributed throughout the house.
The “size” of a ductless air conditioner does not refer to the physical size, but rather to the amount of heat that the air conditioner can remove from a room per hour, which is measured in BTUs (British Thermal Units). No cold air is lost with the ductless air conditioner because there are no ducts to worry about, the system kicks in and heat floods the space immediately. Again, the general consensus is to opt for central air conditioning if you already have air ducts, or without ducts if you don't have it. However, with a central air system, cold air is sent through your oven's air handler to the ductwork, where it is transported to the rest of the house.
For years, air conditioning was considered a nice feature to have in your home, here in the Pacific Northwest, but it wasn't considered a necessity. Mini split air conditioners and multisplit air conditioners are exactly the same units that use a heat pump to push heat in and out and refrigerant to cool the passing air. Since most municipalities require HVAC contractors to have a valid heating and air conditioning license, as well as liability and workers' compensation insurance, it would be prudent to verify your credentials before signing on the dotted line. Depending on the type of home you have, the climate you live in, and the layout of your home, you may want to invest in central or ductless air conditioning.
