Single Zone vs Multi Zone, Which Ductless Air Conditioner is for me?
Say you’ve decided to install a ductless mini split system. After weighing all the pros and cons, you’re convinced that this is your best cooling and heating option for your home. And you have the money, or maybe a solid credit score to back your financing deal for an HVAC purchase. Basically, you’re ready—even anxious—to invest on a ductless system and get the ball rolling right away. Everything seems to be going well and perfect, except that you’re in a little bit of quandary. You’re not sure which one to choose for your ductless mini split application: Should you go for a single-zone or opt for a multi-zone? To help you come up with the best decision, this article answers the following important questions: 1. What is ductless mini split zoned cooling and heating? 2. How does zoned cooling and heating work? 3. What are the control options? 4. What are your zoning options? 5. What is single-zone cooling and heating? 6. What is multi-zone cooling and heating? 7. What are your outdoor unit and indoor unit choices? 8. What are the main differences between single-zone and multi-zone cooling and heating? 9. When does single-zone cooling and heating work best? 10. When does multi-zone cooling and heating work best? 11. What are the benefits of zoned cooling and heating? 12. Single-zone or multi-zone: Which one is the best choice for your home?
In zoned cooling and heating through ductless mini split system, the temperature in each zone is independently regulated and controlled via a designated thermostat or remote controller. This means that you can set different levels of temperature in different rooms or even decide to turn on or off the indoor unit in each room without any impact on the rest of the units. How many zones you designate and how many indoor units you will use throughout the home will really depend on the number of rooms or spaces that you need to heat or cool.
The multi-zone cooling and heating requires one compressor which is connected to two or more indoor units. The number of indoor units depends on the number of zones or rooms that you have targeted for cooling and heating. Typically, one compressor unit can be connected to up to eight air handlers or indoor units.
While conventional single-room HVAC systems, like room air conditioners for example, can be practical options in many ways, single-zone cooling and heating through ductless mini split system remains the best choice. That is, if you’re looking for higher efficiency, performance, and savings. This is in addition to the fact that traditional systems do not always work as well you’ve expected based on your specific requirements, expectations, and situations. In particular, single-zone cooling and heating using mini split works best in the following conditions:
• When you are adding room to your home.
• When you are converting an area of the house into a new functional space.
• When you are constructing a new home or remodeling a house.
• When you are upgrading or replacing a part of your old cooling and heating system.
Why these given situations merit the need for single-zone cooling and heating via ductless system is due to two simple reasons:
1. Ductwork is an issue.
2. Energy-efficiency is a must.
Despite the many advancements in HVAC solutions, it can’t be denied that most of the cooling and heating issues that many households grapple with are directly caused by the limitations that are inherent to traditional, ducted systems. Luckily, the single-zone ductless systems provide a perfect workaround when you want to cool or heat a room where ductwork is not possible or cost-effective. Offering precise temperature control, your single-zone ductless system will enable you to effectively cool or heat any room (like garages, attics, basements, etc.) where ductwork is not present, can’t be installed, or expanding it might be too expensive, not practical, or just entirely not possible.
In view of the many cooling and heating challenges that we face with regard to traditional HVAC systems, zoned cooling and heating via mini split systems provide the following benefits:
• Precise Temperature Control. Zoned cooling and heating enables you to effectively cool or heat a specific room, zone, or any space targeted for climate control whenever you want to and as as conveniently and as easily as possible.
• Customized Comfort. Zoned cooling and heating enables you to select the temperature for any room based on your specific needs or preference, which in effect, allows you to experience more personalized comfort
• Powerful Cooling and Heating. Ductless mini split systems are typically designed with advanced HVAC technology. When used for zoned cooling and heating, you can be assured of maximum comfort regardless of the type of installation.
• Cost Saving. Typical ductless mini split systems, consume less energy even when cooling or heating at full capacity and at a longer period than traditional systems. Using these systems also enables you to completely avoid the usual problems that are related to loss of cool or warm air. Additionally, mini splits have excellent level of energy efficiencies as attested by their high SEER and EER ratings as well as Energy Star certification. If you’re looking to really drastically reduce your utility bills and gain more savings in the long term, then choosing ductless units for zoned cooling and heating is a no-brainer decision.
• Versatile Applications. The lack of requirement for ductwork as well as the compact and unobtrusive design of mini split systems only make zoned cooling and heating the best option for your unique applications.
