Selecting the appropriate HVAC system is crucial for comfort, energy efficiency, and long-term cost-effectiveness. So, learning as much as you can about your options is the best way to find the right setup for your living space.
Here, our HVAC experts will delve deeper into the inner workings of mini-splits, explore their many benefits, and answer a few frequently asked questions. Let’s get started!
How Do Mini-Split Air Conditioners Work?
One of the most common questions we get about mini-split systems is, “how does a mini-split work?” To put it very simply, mini-split systems work by transferring heat between indoor and outdoor units through a refrigeration cycle.
Main Components of a Ductless Mini-Split System
- Outdoor Unit: Also called the outdoor compressor unit, the outdoor unit houses the compressor, condenser, and fan. It’s responsible for releasing heat outside.
- Indoor Unit(s): Located in the room you want to cool or heat, each indoor unit contains an evaporator, fan, and air filter.
- Interconnecting Lines: These refrigerant tubing lines connect the indoor and outdoor units.
- Mini-Split Controls: Typically a remote control, but can also be a wall-mounted unit or smartphone app.
The Cooling (or Heating) Process
- Heat Absorption: The indoor unit’s evaporator coil contains refrigerant. Warm air from the room is drawn in by the outdoor compressor unit, then passes over the indoor unit’s coil. The refrigerant absorbs heat energy from the outside air, cooling it down.
- Refrigerant Circulation: The now warm refrigerant is transported through the refrigerant tubing to the outdoor mini-split unit.
- Heat Release: The outdoor unit’s compressor increases the refrigerant’s pressure, releasing the absorbed heat energy into the outside air via the condenser.
- Refrigerant Return: The cooled refrigerant flows back to the indoor unit.
- Air Distribution: The indoor unit fan activates to push in cooled air, blowing a refreshing breeze into the desired location.
The Benefits of Mini-Split Air Conditioners
Combined heating and cooling capabilities aren’t the only advantages provided by a new mini-split — benefits abound! Here are a few of the many reasons so many homeowners are investing in ductless mini-split systems:
Energy Efficiency and Cost Savings
Ductless heat pumps and ductless air conditioners are renowned for being energy-efficient. Unlike traditional air conditioning systems, which lose air through ductwork, ductless air conditioners can distribute cool air directly to the desired room. The system efficiently maintains indoor temperatures with ease, eliminating energy waste and significantly reducing your energy bills. Additionally, their zoning capabilities allow you to cool or heat only the occupied spaces, making them even more energy-efficient.
Better for the Environment
Because they’re more energy-efficient, ductless mini-split systems have a smaller carbon footprint compared to traditional air conditioning systems. They contribute to reducing greenhouse gas emissions and minimizing your environmental impact. Moreover, many ductless mini-split systems use eco-friendly refrigerants, further enhancing their sustainability.
Flexibility and Zoning Capabilities
Ductless mini-split systems offer unparalleled flexibility in cooling and heating individual rooms throughout your home without the need for clunky and inefficient window units. You can install multiple ductless indoor units to create different zones, each with its own temperature control. This is ideal for homes with varying temperature needs, such as sunlit rooms or bedrooms. You can also add a ductless HVAC system later without major renovations, making it a versatile solution for growing families or changing living arrangements.
Easy to Install
Installing a ductless mini-split system is significantly simpler and less invasive than installing a traditional HVAC system (such as a central air conditioner or furnace). There’s no need for extensive ductwork, reducing labor costs and disruption to your home. The outdoor unit is typically placed on a patio or balcony, and each indoor unit is mounted on a wall. This makes mini-splits a convenient choice for both new and existing homes.
Quiet Operation
Are mini-splits noisy? Not at all! In fact, mini-split units are known for their quiet operation. The compressor, the noisiest component, is located within the outdoor unit, reducing noise levels while still controlling air temperature effectively. This creates a peaceful and comfortable environment, making ductless mini-split units ideal for bedrooms, home offices, or any area where noise reduction is essential.
Improved Indoor Air Quality
Did you know that ductless HVAC systems can actually help you breathe cleaner, healthier air? Many mini-split air conditioning systems come equipped with advanced filtration technology that effectively remove allergens, dust, and other pollutants from the air. This can significantly improve indoor air quality, benefiting individuals with allergies or respiratory sensitivities. Don’t forget to check and change the filter on your ductless air conditioner every three months (or more often depending on how hard your heating and cooling system is working). We can replace filters for both your outdoor and indoor unit, so don’t hesitate to give our friendly team a call for mini-split maintenance.
Applications & Ideal Scenarios for Mini-Splits
Homes Without Existing Ductwork
Ductless systems are the perfect solution for homes that lack traditional ductwork. Whether you’re in an older home without ducts or a newly constructed building where duct installation is impractical or expensive, mini-splits offer a cost-effective way to enjoy climate control without energy waste. With no need for the extensive modifications required by conventional systems, we can quickly and easily install a ductless air conditioner or combined heating unit to enhance heating and cooling capacity in any room.
Room Additions or Renovations
When adding a room to your home, mini-splits provide a flexible and efficient way to extend your climate control system. Instead of dealing with the complexities of extending ductwork for a central system, our heating and air conditioner technicians can install a ductless indoor unit in the new space with only a small hole for a power cable. This allows you to customize the temperature and air quality within the addition without impacting the rest of your home’s HVAC system. Ductless mini-splits are also ideal for renovations where ductwork might be inaccessible or damaged.
Specific Areas Requiring Individual Temperature Control
Ductless systems excel at providing precise temperature control for specific areas of your home. You can independently adjust the temperature in each room without affecting the rest of the house, ensuring that your system delivers cool air or warm air only when needed. This level of control is unmatched by traditional heating and air conditioning systems.
How to Choose the Right Ductless Mini-Split System for Your Home
Selecting the perfect ductless mini-split air conditioner or heating system involves several key considerations, including:
Size
Size matters a lot when it comes to HVAC units! While you may assume that larger units are always more effective, there is such a thing as “too much of a good thing” in the world of mini-split AC. Undersized ductless AC units struggle to cool or heat, while oversized ones waste energy, so determining the appropriate size is crucial for optimal performance and energy efficiency.
Efficiency Rating
While shopping for a ductless mini-split AC or heating unit, look for high Seasonal Energy Efficiency Ratio (SEER) ratings for air conditioning and Heating Seasonal Performance Factor (HSPF) ratings for heating. These metrics indicate the efficiency and effectiveness of the heating and cooling system. Energy Star ratings also indicate efficient mini-split performance.
Number of Zones
Decide how many rooms you want to control independently using your mini-split AC system. This will determine the number of indoor units required. The average ductless air conditioner system can handle up to five indoor units per one outdoor unit, although this can vary. If you have an existing central air conditioning system, you probably won’t need an indoor unit in every room of your house.
Don’t DIY!
Correct mini-split installation is essential for optimal comfort, performance, and efficiency, so make sure to hire a company with experience in ductless AC systems and mini-split heat pumps. In addition, after your ductless mini-split system is installed, don’t forget to schedule regular professional tune-ups for both your indoor units and outdoor unit(s).
