If there’s one thing that Texans must consider when searching for the perfect home heating and cooling system, it’s that the summer weather here can be extremely hot. Finding the right system isn’t just about comfort — it’s a necessity.
Among the various options available, ductless mini split AC units are gaining popularity for their precise temperature control, energy efficiency, quiet operation, and relatively easy installation process without the need for extensive ductwork retrofitting.
But what exactly is a ductless mini split air conditioner, and how does it work? In this quick guide, we’ll outline everything you need to know, including a comprehensive list of pros and cons and a pricing guideline.
A ductless mini split is a type of HVAC system (heating, ventilation, and air conditioning) that can both heat and cool specific zones within a building without ductwork. Ductless mini splits are highly energy efficient which means they can help reduce your energy bills compared to other heating and cooling systems like central air or furnaces.
A ductless mini split air conditioner consists of two main components:
Unlike traditional HVAC cooling systems that rely on ducts to distribute conditioned air, mini split AC setups use a small conduit to connect the outdoor unit to your indoor units. This streamlined system helps reduce energy losses while also offering versatility in terms of cooling capacity.
The most essential difference is that a central air conditioner cools your entire home. Conversely, each indoor unit in a ductless mini split system can be controlled independently, allowing for customized comfort across multiple rooms. Not only does this make ductless mini split systems more energy efficient, but it also means you can take a more flexible approach to your cooling needs by catering to individual preferences for temperature control throughout your living space.
Ductless air conditioners operate by absorbing warm air from inside a room and transferring it outdoors through refrigerant tubing. The outdoor compressor and condenser unit processes the air delivered by the refrigerant lines and transfers cool air back into your home via the indoor air handlers.
So, that’s your summer cooling solution explained. But what about during the colder months when air conditioning typically takes a backstage? Are mini splits good for heating, too?
They sure are! The best ductless mini split systems are designed to work in a range of different temperatures and are well-equipped to deal with colder conditions. Mini split heat pumps extract heat from the outdoor air, even in cold temperatures, ensuring efficient heating during Texas winters.
Before investing in a ductless air conditioner, carefully weighing the pros and cons is essential to ensure it’s the right choice for your household. Let’s explore the various factors you’ll need to consider.
There are numerous advantages of a ductless mini when it comes to enhancing the comfort and functionality of your home. Here’s a list of the primary benefits.
Optimizing energy usage throughout your home becomes easier because each interior unit has its own thermostat and remote control. Plus, because there’s no complex internal ductwork connecting each split air conditioner to the outdoor compressor unit, air leakage is minimized, preventing unnecessary energy loss. To ensure maximum efficiency, always look for units with a high SEER (Seasonal Energy Efficiency Ratio) rating.
As we’ve already highlighted, ductless mini split installation is typically more straightforward than other home cooling solutions. Only one small hole is needed to fit the conduit and suction tubing. However, as at least one or two units will likely be wall or ceiling-mounted, it’s always best to hire a professional for installation to ensure maximum safety and minimum disruption to your daily life.
The ability to heat and cool rooms in your home independently of each other enhances comfort and can significantly reduce your electricity consumption. For example, you could turn off the air conditioning in your home office on the weekends. If multiple people live in your home, they all could choose their own temperature settings in different bedrooms.
Maintaining a healthy living environment and taking steps to improve indoor air quality are essential considerations – especially in households with family members with allergies or compromised immune systems. Split air systems contribute to improved air quality by eliminating the potential for dust, mold, and allergens that can accumulate in internal ductwork and vents.
There are several design styles to choose from, including wall-mounted, ceiling-suspended, and freestanding floor options. This design versatility ensures both aesthetic appeal and functional efficiency, ensuring your ductless mini split air conditioner blends seamlessly into your home decor.
Mini splits are an excellent option for enhancing home comfort levels without having to worry about the disruptive noise of a central air conditioning system. Traditional HVAC systems typically generate indoor noise levels between 50 and 75 decibels (dB), whereas a ductless mini split system runs at less than half that, producing only 25 to 35 dB of noise.
While there’s no denying the many advantages of a ductless mini split air conditioner, it’s essential to understand the potential drawbacks and challenges so you can make a well-informed decision. Let’s explore the most common disadvantages.
The initial investment in a ductless mini split air conditioner can be higher compared to some traditional HVAC systems. The average ductless mini split cost is around $4,500 for a standard system. However, the U.S. Department of Energy estimates ductless systems reduce energy usage by 30%, translating to significantly lower utility bills in the long run.
Running a ductless mini split AC system involves careful monitoring. It’s not simply a case of connecting the power cable and leaving it to do its thing, as neglecting maintenance can lead to increased energy usage and potential system failures. Essential tasks include:
While zoning has its advantages, a ductless mini may struggle to cool or heat large areas effectively. As a general rule, one ductless mini split AC unit is suitable for a single room or small apartment. However, more indoor units are required for homes with several rooms or larger spaces. For multi-story homes, several additional units may be necessary, increasing both the ductless mini split installation cost and overall energy usage.
Homes with older heating and cooling systems may require significant modifications to accommodate each new unit and component. While there’s no need to install ductwork, you may still need to:
Unlike a central air conditioner which has hidden ductwork and vents, mini splits require a visible presence. Despite their compact, contemporary, and often sleek appearance, the visibility of indoor units remains a consideration for homeowners prioritizing a seamless and unobtrusive look that won’t interfere with interior design elements or furniture placement.
While the average price we mentioned earlier is a fair yardstick, extremes at either end of the range vary between $1,200 and $16,400, depending on:
Specifics vary based on room size, layout, and cooling requirements. However, you should plan on placing one ductless mini split air conditioner unit in each room unless it’s a relatively large and open space, in which case an additional unit may be required to provide sufficient cooling. If your home has more than four rooms you’d like to cool, you should check with an HVAC expert to determine whether you need a multi-zone system.
Updating or upgrading your heating and cooling systems to improve energy efficiency is always a wise decision. But it’s not the only way to cut costs. As you consider the energy-saving benefits of a ductless mini split system, remember that selecting the right electricity plan is equally crucial. An electricity plan aligned with your energy usage and needs can significantly reduce your energy bills.
