Mini-Split Systems, What Are They and Are They Worth It?

Did you know that according to Wisconsin's Focus on Energy website, heating and cooling accounts for nearly half of your household energy usage? This means that a heating and cooling system is the highest energy user in a typical household.

In a bid to reduce costs on utility bills, there has been an increase in demand among homeowners for cost-effective heating and cooling alternatives. One that could offer both efficiency and comfort while allowing them to save significantly on energy bills.

Today, there's no smarter, more cost-effective way to keep your home cool than investing in a ductless mini-split system. Because of its design and features, you can save up to 30% on your household utility bill through mini-split systems (as compared to traditional systems).

In this article, you'll learn what mini-splits are and whether they are worth the hype. You'll also get answers to some of the most frequently asked questions (FAQs) about this high-energy efficient ductless heating and cooling system.

What Is a Mini-Split System?

A mini-split system is an alternative to the traditional HVAC system. It's an innovative heating and cooling system that got its name from its design and how it functions.

The term "mini'' refers to the smaller size and compact design of the system as compared to the traditional HVAC system. The smaller size makes this unit great for mounting on the wall or ceiling, while the compact design makes the units easy to install and allows placement flexibility.

The term ''split'' in a mini-split system implies that the unit is separated/split into two main functional components. The refrigerant lines and electrical wiring link these two components, creating a ''split'' system. The two components are:

1. An outdoor unit consisting of the compressor and condenser, which circulate refrigerant and heat extracted, respectively
2. An indoor unit containing the evaporator which delivers conditioned air to specific areas or zones

It's worth noting that a mini-split system can come in two distinct configurations depending on the number of indoor units connected to the outdoor unit. When it comes to this end, the choice of your mini split may depend on your desired level of climate control and the size of your space.

The two system configurations are:

3. Single-zone mini split—consists of one indoor unit for one outdoor unit
4. Multi-zone mini split—consists of multiple (2-4) indoor units for one outdoor unit

In short, ''mini-split'' refers to a small, compact heating and cooling system with outdoor and indoor components. It's also known as a ductless mini-split system and offers an individualized level of climate control to specific rooms or zones within a building.

Where Can a Mini-Split System Be Installed?

Thanks to its small, compact design, you can install a mini-split system in various locations within your home. However, the location and style of the mini-split are crucial to receiving optimal conditions. Based on the method of installation, let's take a look at some common types of mini splits out there:

1. Wall-Mounted Mini Split

This is the most popular and straightforward installation option for a mini-split unit. As its name implies, it involves mounting or placing a mini split high on the wall (just below the ceiling). This installation option or method is ideal if you want the unit to deliver conditioned air throughout the room. It's commonly used in residential settings.

2. Floor-Mounted Mini Split

This is an alternative installation method for spaces with limited wall space, or ceilings that are too low. Here, a mini-split is installed on a wall at or near floor level. This mini split type is ideal for rooms with large windows or spaces where a low-profile unit is desired (such as in sunrooms or offices).

3. Ceiling-Cassette Mini Split

These mini splits are installed on the ceiling. Its installation involves hanging the unit from the ceiling using brackets or chains. This particular installation option allows a wider circulation of conditioned air than most other options. It’s ideal where there’s limited wall space. Many homeowners who don’t want their HVAC system to take up wall space or want to keep their indoor units out of sight might prefer this option.

How Efficient Is a Mini-Split System?

Mini-split systems are particularly efficient in many ways compared to traditional HVAC systems. According to Energy.gov, traditional HVAC systems use ducts and, as a result, account for over 30% of energy consumption to provide the heating or cooling needed. They often feature centralized units that deliver heating and cooling to the entire house, resulting in energy losses in unoccupied rooms.

On the other hand, mini-split systems operate without the need for ducts. And this helps eliminate the energy loss associated with ductwork. This feature (combined with other features of a mini split) allows the units to deliver more efficient heating and cooling. It will also result in potential energy savings, reducing household energy consumption by up to 30% compared to traditional HVAC systems.

People who want to meet their household heating and cooling needs demand the most energy-efficient heating and cooling options. And as a result, they're opting for mini splits to reduce energy consumption and lower utility bills, saving big on energy costs.

Is a Mini-Split System Loud?

Mini-split systems are designed to provide unobtrusive cooling and heating. Mini-splits (indoor units) typically have noise reduction features and perform their operations at lower decibel levels.

Some modern mini-split systems are equipped with sound-dampening technology to make them extremely quiet. These units also feature advanced fan designs that help minimize noise levels when the units are in use.

However, their outdoor unit does produce some noise during operation. But the noise level is generally lower than what you may experience from larger central conditioning units.

Can I Use a Mini-Split System for Both Heating and Cooling?

Yes, mini-split systems are designed to provide two modes of operation: cooling mode (for cooling) and heating mode (for heating). They use heat pump technology which allows the units to transfer heat from the outdoor unit to the indoor unit for heating or from the indoor to the outdoor unit for cooling. It’s important to note that in cold climates you will need a supplemental source of heat when the temperatures are particularly frigid. Any temps below -14° and the heat pump will not be capable of pulling enough ambient heat out of the air to produce heat, and you will need to rely on a backup heat source.

How Many Mini-Split Systems Do I Need to Be Effective?

The total size of the space will determine the size and number of mini splits you'll need for optimal heating and cooling of your home. This also includes the power capacity needed for the systems. In general, the larger the space where you need these systems, the larger/more systems you'll need for adequate coverage.

Homes with larger spaces featuring multiple rooms or zones may require multi-zone mini splits to effectively heat and cool the entire space. A single-zone mini split is generally only used to heat or cool one room and is great for additions to your home such as sunrooms where you might not want to spend the extra money on installing ductwork.

In measuring your home's size and layout, you need to consider factors such as your:

space's square footage
ceiling height
number of windows
insulation levels

These factors will assist you in the proper estimation of the number and placement of indoor units needed for your space. An HVAC professional best handles these calculations.

Number of Rooms

Suppose you have multiple rooms or areas in your home that require different temperature settings. In that case, a separate indoor unit for each room or zone is required for individualized adequate climate control.

Your Load Calculation

Load calculation (aka heating and cooling load calculation) is a way used to determine the heating and cooling requirements of a home, building, or space. This is estimated in British Thermal Units (BTUs) or kilowatts (kW).

This process involves evaluating certain factors affecting the heat gain or heat loss in the area where heating and cooling are required. This helps determine the ideal capacity or number of mini splits your home needs to maintain desired climate settings.

These factors may include:

climate
ventilation
building orientation
windows and doors
insulation
occupancy and internal loads

HVAC professionals would consider these factors when calculating the load calculation using manual methods or specialized software. The results of your home load calculation will guide the HVAC professional in determining the appropriate number and capacity of mini splits needed.

How much does a mini-split system cost to install?

The installation cost of a mini-split system fluctuates based on the type of system (single zone or multi-zone) and the number of units needed.

Typically, a single zone system tends to average at approximately $9,000, covering both the components and the installation. On the other hand, a multi-zone system's total cost can reach up to $15,000, depending on the number of units being installed. While they may appear somewhat expensive initially, these systems prove beneficial over time by reducing energy expenses annually.

It's Summer Party Time! Create the Perfect Space For Outdoor Get Togethers

Simple Additions That Make the Most of Outdoor Living Spaces

Summer is a time to be outdoors and share memories with friends, but if the neighborhood or friends group doesn’t have a regular place to gather, it can be difficult to celebrate. Homeowners can design a backyard space that is perfect for entertaining and will provide an atmosphere that breeds comfort and enjoyment with just a little thought and the help of an electrician.

Install Strategic Exterior Lighting

Outdoor lighting can be both practical and decorative. It helps keep the outdoor area visible, allowing the party to go well into the night, and exterior lights can also be used to create a festive mood. A few examples that fit both the practical and decorative categories are examined in the following paragraphs.

Motion-Sensor Lights: These lights are handy for driveways and backyard spaces that animals might use.
Pathway Lights: These are usually used along a sidewalk area to provide a good visual of the path and allow navigation.
Step Lights: These particular lights are often embedded in the steps leading up to a porch area to help people navigate the stairs, even in low light. They are usually placed vertically so that they shine out onto the step.
String Lights: While string lights are always great for a party look, they have the practical aspect of lighting up the yard while creating a romantic atmosphere.
Solar Lights: These outdoor lights are often seen in the gardening section of local department and hardware stores at this time of year. They save money using only solar energy and provide a nice LED light source perfect for lighting paths or flowerbeds.
Spotlights: These can be good for when a homeowner has to let pets outside or, as a decorative measure, to highlight certain landscaping areas, such as a tree.

Invest in a Generator

Even exterior lights can help save a get-together if there is a power outage. Summer is often when outages occur due to increased air conditioner usage. Not only are power outages inconvenient, but they can also be dangerous for vulnerable people who may depend on electricity to run certain things they require for their health. This is why homeowners with these concerns should consider purchasing a power generator. It can take the pressure off and keep a summer gathering going. The benefits of owning a generator are contained in the list below.

A generator keeps the refrigerator and freezer going, preventing food spoilage
A generator keeps the air conditioning going to keep the home cool
A generator keeps the lights on
A generator will power security systems and life-saving devices in a power outage

Take the Plunge for a Pool or Hot Tub

What could make a summer more perfect? The only real answer is a pool or hot tub. While these are significant financial investments, they are also a way to increase the value of a home and curb appeal. The main problem with a pool or hot tub is ensuring a professional safely and properly wires it. It must be done according to regulations and local laws to keep everyone safe from electric shock.

How Does a Whole House Dehumidifier Work?

Schedule Service

You know that feeling when you step into a room and the air feels heavy and sticky? Well, that's what high humidity does to your living space. Excessive humidity in your home can take a toll on your well-being. It's not just an inconvenience, but it can make you feel sick or downright uncomfortable.

Other risks come along with too much moisture in the air. It can lead to unexpected health issues, which is the last thing anyone wants. Plus, you could end up dealing with fungus, mold, and dust mite growth, which can be a real headache to get rid of. And let's not forget about the damage it can cause to your wooden furniture and other items indoors.

If you have asthma or allergies, excessive humidity can worsen your respiratory problems. Therefore, it's essential to keep an eye on the humidity levels in your home and take action if things start to get too damp. Your health, comfort, and belongings are at stake, and nobody wants to deal with the consequences of excessive moisture.

Luckily, there's a solution that can help keep the humidity levels in your home under control. Installing a whole-house dehumidifier is a game-changer. It's a device that sucks out the excess moisture from the air, saving you and your family from all the risks associated with high indoor humidity.

This amazing gadget works wonders in improving the air quality of your home, especially during those muggy seasons. It's a must-have for places like basements and bathrooms, where moisture tends to accumulate. Let's dive into how the whole house dehumidifier works. By understanding its inner workings, you can decide whether it's the right option for your home.

It's worth mentioning that many homeowners prefer a whole-house dehumidifier over other options like portable or basement dehumidifiers. Why? Well, it's because these devices have comprehensive functionalities. They effectively remove excess moisture from your entire home instead of only a single room.

Okay, let's get into the nitty-gritty of how a whole-house dehumidifier does its magic.

To put it simply, this HVAC system acts as both a cooler and a heater at the same time. It's pretty cool. Several key components work together to achieve the dehumidification process.

The evaporator coil is where the magic begins. It's responsible for removing moisture from the air through condensation.
Then, we have the compressor, which compresses the refrigerant gas in the evaporator and pushes it to the condenser.
The condenser releases the heat into the air, and during this process, the refrigerant cools down and returns to a liquid state.
The fan plays a crucial role. It draws air into the unit and circulates it over the evaporator coil, ensuring that moisture gets absorbed properly.
We certainly can't leave out the humidity sensor. This smart component detects and regulates the humidity level in your home. It's like having a mini weatherman inside your dehumidifier.
Last but not least, we have the condensate pan or reservoir. It collects the condensed water from the air, making it easier to drain out of the unit.

Now that we've covered the main components, let's see how they work together to remove moisture from the air.

First, the humidity sensor keeps an eye on the humidity levels in your home. When it detects that the humidity has risen above a certain threshold (usually between 30% and 50%), the dehumidifier springs into action.
The fan kicks in, drawing humid air from all corners of your home into the unit. The air passes over the evaporator coil, where the moisture gets absorbed and condenses into water droplets. These droplets are collected in the condensate pan or reservoir.
To ensure the air leaving the dehumidifier isn't too cold, it is reheated and brought back to room temperature. The dry air is circulated back into your home, through your HVAC system. As the dry air mixes with the rest of the air in your home, the overall humidity level decreases, creating a more comfortable and healthier indoor environment.
As the ‘moisture absorbing’ device removes moisture from the air, the water that drips into the condensate pan must be emptied regularly. You can connect or direct your whole house dehumidifier to your drainage system or use larger water reservoirs. This way, you’ll be saved from the stress that comes from the frequent emptying of your reservoir.

So, that's how a whole house dehumidifier works. It's a pretty fascinating device that can make a world of difference in maintaining a comfortable and moisture-free home.
