Mini-Split Fit Guide: Single Zone or Multi-Zone?
MAY 6, 2024, BY MR COOL
You’ve decided the best option to keep your space comfortable is a MRCOOL® mini-split system, but now you aren’t sure if a single zone or multi-zone unit is the best fit for your needs.
It might seem like all you need to ask yourself is how many rooms you want to heat and cool with your mini-split system, but there are a few other factors you should consider. Let’s start by covering some basics.
How Do Mini-Splits Work?
The main components of a mini-split consist of an outdoor condenser and one or more indoor air handlers. When in heating mode, the condenser absorbs heat to send inside via the refrigerant where the air handler releases and disperses that heat throughout the room. In cooling mode this process occurs in reverse, as heat is absorbed from indoors and moved outside. The air handler uses those gasses to change the temperature and ventilates cold or heated air into your space.
Basically, a mini-split heating and cooling system moves heat energy around instead of producing it. Mini-splits don’t require expensive ductwork and are more efficient.
You might already know how a mini-split works, because you’ve decided a MRCOOL® mini-split is the solution for you. The next step in finding the ideal heating and cooling solution is to decide if you want one or more than one indoor unit. As you’ve likely figured out, a mini-split with one indoor unit is single zone, while a mini-split with two or more indoor units is multi-zone.
Think of zones as different rooms in your house or office. The kitchen is one zone. A home office is one zone. The family room is also, you guessed it, one zone.
Our multi-zone mini-split systems can support up to five separate zones.
Benefits of a Single Zone Mini-Split
A single zone ductless system is the most straightforward HVAC option for managing the comfort of a room. This type of appliance uses one condenser, one air handler, a line set, a communication cable, and a condensate drain line.
Benefits of choosing a single zone system include:
- Lower initial cost: Installing this type of mini-split is simpler, which means the initial purchase cost and installation fee is less. If you opt for a DIY® unit, single zone systems require less time and consideration to install.
- Energy efficiency: Since single zone mini-splits are one-to-one, they minimize energy usage and provide the most optimized performance, making them the most efficient choice for a single space.
- Lower carbon footprint: Single zone units are excellent for people who are climate conscious.
- Easier maintenance: Our single zone mini-splits are built with easy to clean filters that keep them running efficiently.
You might think with all these benefits, a single zone is clearly the winner. Before making your decision, let’s go over the benefits of the second option, a multi-zone mini-split.
Benefits of a Multi-Zone Mini-Split
The function and operation of a multi-zone mini-split are very similar to a single zone unit. Ductless multi-zone mini-splits use the same components. The only difference is that they require multiple air handlers, line sets, and other accessories.
Multi-zone mini-splits offer reliable performance and allow you to customize how each space feels with only one outdoor condenser unit. Other benefits include:
- Controlled, customized environment: You can tailor the air temperature of each zone of a multi-zone system to your personal desire. For example, your kitchen might get extra hot when baking goodies or cooking dinner in peak summer months. With a multi-zone cooling system, you have the flexibility to adjust the temperature so that one room can be made cooler than others in your house, ensuring that individuals in different areas aren’t subjected to uncomfortably cold temperatures.
- Fewer outdoor units: If you have limited outdoor space, a multi-zone unit serves a wider area with only one outdoor condenser.
- Eliminate wasted energy: You can turn off or significantly limit the heat and air for rooms that are empty most of the day.
Let’s go through some scenarios for each mini-split option to better understand which ductless HVAC system will serve you best.
When to Choose a Single Zone System
- You are adding on to an existing structure. Add-ons typically aren’t connected to existing HVAC systems. An excellent option to heat, cool, and ventilate new construction is to install a single-zone mini-split.
- You’re renovating your space. Renovations may not fit with your current heat and air system. To avoid costly reconfiguration you can install a single-zone mini-split to manage the comfort in tandem with your current HVAC.
- You don’t want to use a window unit. Many homeowners have a garage or workshop outside their house. Instead of using a bulky window unit, install a single zone system so you can continue opening windows on those perfect spring days.
- You have one space that needs extra climate control. Maybe you have an attic that is underserved with your current system and gets too hot. Install a single-zone mini-split to better control the temperature and protect heat sensitive items stored in the extra space.
- Your space is on the small side. Even with multiple rooms, small cabins or tiny houses might only need a single-zone system to stay comfortable year round as long as there are fans for adequate airflow. Make sure to check the capacity of the single-zone system to ensure it fits your needs.
When to Choose Multi-Zone
- Your building has multiple floors. We all know heat rises. Keep your upstairs cool without freezing the main level by installing a multi-zone system that allows you to make temperature adjustments per level or room.
- You live in an old or historic home. Older homes can pose a challenge when new ductwork is required to keep you and your loved ones comfortable. Instead opt to install a multi-zone mini-split. It’s less invasive than running ducts through the walls in every room.
- You have rooms that go mostly unused. Be more energy efficient and save money on your utilities by installing a multi-zone unit that allows you to turn off or significantly reduce the temperature control in rooms that aren’t used often, such as storage areas or formal sitting rooms.
You need to customize the climate for sleeping spaces. Different people can want or require a specific temperature to fall asleep. Comfortable to one person might be freezing to another. Keep everyone well rested and happy by getting personalized, custom climate control with a multi-zone HVAC system.
Which Mini-Split Is Right For You?
Ultimately, you should consider cost, building requirements, space allotment, and other situational factors to determine whether a single zone or multi-zone mini-split is the best option for your needs.

Spring Cleaning Tips, Q124
5 Spring Cleaning Tips for Your HVAC
They don’t call it spring cleaning for no reason — those mild days between winter and summer are the perfect opportunity to start fresh with a clean home. As you work on your spring cleaning to-do list, be sure to dedicate time to cleaning your HVAC.
Cleaning your HVAC can help keep it in good condition and prepare it to work hard in the upcoming hot summer months. Check out our spring HVAC maintenance checklist for tips on cleaning this pivotal element of your home.
Why Is it Important to Spring Clean My HVAC?
Spring air conditioner maintenance is necessary for several reasons:
- To keep it performing at its best: Regularly cleaning your HVAC can keep it operating well with minimal issues. Your HVAC system makes your home comfortable, so you want to give it the attention it needs to keep it in great shape.
- To clear out dust after winter: You likely kept your windows and doors sealed tightly throughout the cold winter months, meaning the air inside your home continuously recirculated. Without an outlet, dust, dirt and debris could have built up and settled in your HVAC ducts, affecting the indoor air quality.
- To prepare it for summer: Your HVAC has a big job when temperatures rise in the summer. Spring HVAC maintenance lets you identify any problems or concerns and have them addressed by a professional before summer arrives.
How Do I Prepare My HVAC Unit for Spring?
Now that you know why it’s important to spring clean your HVAC, let’s talk about how to make it happen. Put the following spring HVAC cleaning tips on your to-do list to enjoy a cool and comfortable summer:
1. Replace the Air Filter
Air filters catch dirt, dust, hair, allergens and other debris before they reach the blower fan. Air filters keep your home’s air quality in top condition by preventing contaminants from recirculating.
Changing your air filter is crucial for a healthy, efficient HVAC system. Once the air filter becomes soiled with debris, it can’t trap contaminants as effectively, resulting in poorer air quality. Additionally, your HVAC system will have to use more energy to pull air through the clogged filter, leading to a higher electricity bill.
At a minimum, you should replace your air filter twice yearly. For best results, change it monthly, especially if you have pets in the home. Our mini-split systems feature washable filters, which are an extremely convenient and cost-effective solution for keeping the air in your home clean.
2. Clean Your Condenser
The condenser is the large, box-shaped component outside your home. To run properly, your condenser should be clear of any obstructions, such as plants, rocks, leaves, weeds, sticks, dirt and other debris. Head outside and remove any of these items from the unit and the area surrounding it.
Smaller debris like grass and dirt particles can get lodged inside the unit. Spray it down with a low-pressure water hose to remove any small obstructions. Our MRCOOL® Cleaning Kit is the perfect option for ensuring your system is thoroughly clean.
3. Clean the Condensate Drain Pipe
Condensate lines flush excess moisture out of your HVAC system. Excess moisture is a normal part of HVAC systems because they produce humidity, which creates condensation. A pan under the unit inside your home collects the excess moisture. From there, it drains into the main condensate line and drips out of a pipe on the exterior of your home.
Just like air filters, drain pipes can become clogged and ineffective. A clogged pipe can cause the drain pan to overflow, leading to leaks and water damage in your home. It’s important to check your drain pipe in the springtime for any rust, dirt, algae or other obstructions to avoid this issue.
If you’re up for a DIY project, you can clean your HVAC drain pipe with the following steps:
- Turn off the HVAC: Shut down the thermostat, then head to your breaker box and flip off the switch for the HVAC system.
- Locate the drain line: The drain line is a black, gray or white PVC pipe attached to your home near the outside AC unit that leads to a drain pan.
- Locate the drain line’s access point: The access point is typically near the drain pan and features a cap or cover. Remove the lid and inspect the inside of the pipe, clearing out any debris you see.
- Flush the line with distilled vinegar: The acid in distilled vinegar breaks down sludge and clogs while also killing bacteria and mold. Pour it directly into the drain line and let it sit for at least half an hour. The longer it sits, the cleaner your line will be.
- Rinse with water: Once the vinegar has worked its magic, flush the line with water. Watch the water stream that flows from the drain pan — you’ll know the vinegar was successful if the water drips steadily.
- Repeat as needed: If the water doesn’t drip steadily from the drain pan, your drain pipe is likely still clogged, and it’s a good idea to repeat the process until the water flows freely. Let the vinegar sit for a longer period this time around.
4. Clean Your Entire Home
A thorough spring cleaning does more than improve the appearance of your home. Removing dust and grime can reduce the number of pollutants available to circulate in your home, making your air filter’s job a little easier.
Go from room to room dusting, sweeping, vacuuming and tossing out unwanted clutter. Remember to clean any ceiling fan blades, as these are prime spots for dust collection.
5. Seal and Clean Your Windows
Windows that don’t seal tightly can let outside air seep in, making your HVAC work harder to moderate your home’s climate. Of course, a unit under pressure results in higher energy bills, but a little window maintenance can help you avoid this problem.
Sealing your windows can help ensure that conditioned air stays inside and warm and humid outdoor air stays outside.
Inspect window perimeters for gaps or holes, and check for any drafts coming through. Also, look for any visible condensation within the panes. These are all signs of a faulty window seal. If you notice any of these issues, have the windows resealed or replaced.
You may be surprised to learn that cleaning your windows is another way to help your HVAC run efficiently during those cooler, early spring days. Clean windows allow more sunshine to come through, so you won’t need to depend solely on your HVAC system to warm things up.

Guide to Proper Thermostat Placement, Q423
Guide to Proper Thermostat Placement
Your thermostat constantly monitors your home’s average internal temperature, keeping you comfortable year-round. If you’re experiencing high energy bills or a fluctuating heating, ventilation and air conditioning (HVAC) system, you might have thermostat placement problems. Before contacting a technician, see if your thermostat placement is causing the issue.
General Thermostat Placement Guidelines
If you’re looking for advice on thermostat placement or want to move your device due to thermostat placement problems, you’ll want to select the right location for your device. Thermostat location can affect your home’s climate, changing the correct home temperature and influencing your comfort level inside.
For the best thermostat placement, here are some general guidelines when looking for the right location:
- Keep it away from heat-generating appliances like stoves, ovens, lamps and televisions.
- Avoid the hottest or coldest room of the house.
- Keep sensors from being blocked by shelves and doors.
- Mount it at least 5 feet high off the floor.
- Keep furniture and objects from blocking the thermostat.
- Stay away from plumbing and ducts.
You generally want your thermostat to sit where it can take an average reading of the home’s temperature. Watch out for appliances and systems that could influence the thermostat’s readings to get the most accurate measurement. Prevent anything from blocking or covering the thermostat to help improve the system’s functions.
If you’re moving a thermostat’s location, carefully evaluate each potential section of your house. You’ll want to access the device easily for the most convenient climate control. Improper placement can lead to incorrect readings and increased energy bills, so ensure you’re choosing the best possible location for the device.
The Best Place to Install a Thermostat
Good thermostat placement ensures your device performs efficiently and correctly. You should install your thermostat in a central spot with plenty of air circulation for the best readings. This location should also be easy to access since you’ll want to adjust your thermostat without inconveniencing yourself.
Placing it too high or too low from the floor will influence the temperature the system reads. Since cool air sinks and hot air rises, low thermostats will read cooler temperatures and high ones will state warmer temperatures. Setting the thermostat placement height at 5 feet will give you the best average of your home’s temperature.
To assist you in selecting the best spot, here are some excellent locations for your thermostat:
On an Interior Wall
Interior walls are insulated from changing outdoor temperatures. They won’t warm or cool like exterior walls, allowing your system to get a better read of your home’s climate. Interior placement will allow the thermostat to remain uninfluenced by outdoor temperatures while gaining access to interior air circulation for the best-possible reading.
In a Central Location
Placing the thermostat in a central area will give your device the best measurement of your home’s average temperature. Main rooms are connected to many areas of the house, experience consistent airflow and are less affected by outdoor temperatures. Central locations are also easily accessible, making it convenient for you and your family to adjust the climate as necessary without struggling to reach the device.
On the First Floor
For houses with more than one floor, the thermostat should be placed on the first floor. Heat usually rises, so a thermostat on the second floor will register the house at a much warmer temperature than the average. This can drive up your energy bill, especially during hot summer months, since the device will work much harder more often to compensate for the higher upstairs temperatures.
To get more accurate thermostat readings and control, consider installing a mini-split system for separate rooms. Split systems on each floor allow you to have a different temperature for each location in the house, improving the thermostat readings and keeping your home comfortable.
In a Frequently Used Room
Always install your thermostat in a frequently used room. Placing your device out of the way will affect its readings and the house’s temperature. Less frequently used rooms experience less air flow and different temperatures than the rest of the house.
If you’re using a room often, you want it to sit at a comfortable temperature. Placing the thermostat in this area will make that the most comfortable room in the home and provide better climate control for the whole house.
The Worst Place to Install a Thermostat
Areas with dramatic temperature swings can cause the thermostat to incorrectly read the house climate, making it work more frequently and harder. The more your thermostat adjusts your HVAC system, the more money you’ll spend on energy bills.
To help keep this from happening, avoid placing your thermostat in these locations:
In Direct Sunlight
Direct sunlight hitting your thermostat will affect its readings. Beams of warm light will cause the device to register the interior temperature as warmer than it actually is. This will waste energy and make your thermostat work harder. Even during the winter, sunlight will influence what the device reads the indoor climate as, influencing your comfort level.
Near Vents
Vents send out hot and cold air, which can mess with your thermostat readings. Hot and cold air coming from the vents will influence your thermostat and cause it to turn the air conditioning system on more frequently. Your device can pick up false readings if it’s set above or below a vent, so avoid them if you want the correct thermostat readings.
By Doors and Windows
Drafts and sunlight come in through windows and doors, altering the thermostat and changing the indoor temperature. Air flowing through gaps and cracks or open doors will cause the thermostat to work harder. Even if your average indoor temperature isn’t changing much, these drafts and sunbeams will turn your air conditioning on and off without reaching the correct settings.
Near the Kitchen
The kitchen contains ovens, stoves and other appliances that emit heat throughout the day. This heat can lead to incorrect readings by your thermostat. The device will think the home temperature is much warmer than it is when you’re using the kitchen, leading to air conditioning activation more often.
In Empty Hallways
Empty hallways see minimal air circulation, which the thermostat uses to evaluate the average temperature. Since you aren’t often hanging out in your hallways, move the thermostat to a more common location for the most accurate and comfortable temperature reading.
On Exterior Walls
Exterior walls are more likely to warm or cool according to outside temperatures. Even with insulation, the temperature of these walls will fluctuate as the outdoor temperature does, causing your thermostat to change, as well. To avoid your thermostat reading outdoor temperatures, place it on an interior wall for the best performance.

What temperature Should I keep My Home, Q323
What Temperature Should I Keep My Home?
When you’re trying to find a comfortable temperature for your house, you could spend all day pushing the buttons on your thermostat. Before you spike up your energy bills and drive your family crazy, make sure you’re ready for summer by figuring out what temperature to keep your home.
Whether it’s summer or winter, your home should be at a comfortable temperature all year round. You don’t want to be sweating puddles in the summer or wrapped in blankets in the winter months. Instead, take our advice and find a way to adjust your thermostat so everyone in the house, including your wallet, is happy.
Why Home Climate Control Is Important
While you might not think about the temperature all the time, it affects your house in many ways. Here are some specific reasons for having the right setting on your thermostat in the home:
- You’ll be comfortable: Imagine a world where you’re not shivering in the winter or sweating in the summer. By knowing the right temperature, you can achieve this dream in your own house.
- You’ll save money: The energy your HVAC system spends to heat and cool the air makes up more than half of the energy you use in your house. Adjusting the temperature seven to 10 degrees Fahrenheit for eight hours each day can save you 10% on your electric plan each year.
- You’ll protect your HVAC system: Setting the right temperature will relieve the strain on your air conditioner or furnace. You’ll have a long-lasting, reliable HVAC unit when it doesn’t have to compete with the outside heat or wind.
- You’ll be healthy: The World Health Organization (WHO) recommends keeping indoor temperatures between 20 – 24 degrees Celsius (68 – 76 degrees Fahrenheit) if you’re healthy, but at least 68 if you or someone in your house has chronic health conditions. Setting the right temperature in your home in the cold winter months prevents hypothermia and respiratory issues in children and older adults.
How to Find the Right Temperature for Your House
Finding the right temperature is tricky, especially when you live with others. Consider these factors before you start playing with the thermostat:
- Humidity: Besides adjusting the temperature, an HVAC system also removes moisture from the air. If you live in a humid climate, you should always keep the AC running in the summer, even if it’s at a higher temperature.
- Area of the house: The right temperature for your home might be different throughout the house. Rooms that are in line with direct sunlight are naturally warmer, so they need less heat in the winter. Since warm air rises, you might want to set the thermostat upstairs a little lower than the rest of your home. You could also set the thermostat higher in the basement, where it tends to be colder. Areas of your home with more square feet may also need more of a boost from your thermostat so your HVAC system could provide the proper temperature.
- Time of day: You’ll need to adjust the temperature of your thermostat based on the time. In the summer months, when the sun is beating down on your house, you could lower the temperature on your AC to find relief from the heat. On a cold winter’s night, while you’re sleeping, you can keep the temperature lower to get a better night’s sleep and save money on energy costs.
- Age: Older adults and young children have a lower tolerance to extreme temperatures. If you have people in the house who are at one of these tender ages, you should have a more stable temperature throughout the day to protect their health and comfort.
- Your comfort: Ultimately, the right temperature for your living environment is what makes you comfortable. If you’re one of those people who wear shorts in the snow or a scarf to the beach, you may prefer to have the temperature higher or lower than what we recommend.
The Right Temperature for Your House in the Summer
In the warm summer heat, you need a reliable AC unit that provides home comfort. Besides thinking about your health, you also need to consider how the weather affects your house. Set the thermostat to create a comfortable, dry atmosphere so your furniture and hardwood floors stay in good shape.
1. A Good Temperature for When You’re Home Over the Summer
To keep your thermostat from competing too much with the summer heat, the ideal temperature for your house in the summer is 78 degrees Fahrenheit. Since most people set their thermostats well below this number, you may have a hard time adjusting to this money-saving temperature.
Instead of raising the temperature to 78 degrees right away, you could ease yourself into it. Start at, say, 70 degrees, and then increase it a couple of degrees each day until you reach the magic number. Adjusting the temperature even one degree makes a difference in your energy costs.
2. A Good Temperature for When You’re Away Over the Summer
Whenever you’re out of the house, you should aim for a temperature that’s similar to outside. Setting the thermostat higher over the summer controls the heat coming into your home and relieves the burden on your central air unit. Since AC systems also remove humidity from the air, keep it running at a higher temperature instead of turning it off completely.
Remember to leave the air conditioner on at a safe temperature for your pets or sensitive furniture, even when you’re not home. When you return, you shouldn’t crank the air conditioner to try to rush cold air back into the house. Set it to the energy-saving temperature of 78 degrees and wait for the house to get comfortable.
3. Energy Saving in the Summer
If you have an energy-efficient air conditioner, you’re already saving money on your utility bills each month. To save even more money, follow these safety tips for cooling down your home in the hot summers:
- Close the blinds to keep out direct sunlight on warm days.
- Use ceiling or box fans to circulate air throughout the house.
- Drink plenty of water to produce sweat and lower your body temperature.
- At night, open the windows to give your AC a break and let in a naturally cool breeze.
- Seal any gaps around the doors and windows in your house to protect your living space from air leaks.
- To reduce the production of heat in your house, try to use cooking or heated appliances late at night or early in the morning.
The Right Temperature for Your House in the Winter
Most of us would like to keep our homes heated for as little money as possible. Fortunately, MRCOOL makes it easier to keep your home warm without breaking the bank. Our products could perform zero-degree heating, which means they maintain their money-saving efficiency, even at freezing temperatures.
1. A Good Temperature for When You’re Home in the Winter
While you might want to save money in the winter months, living in a house that’s too cold could make you sensitive to respiratory issues and infections. Set the temperature to at least 18 degrees Celsius, or 64.4 degrees Fahrenheit, while you’re in the house.
When your home, the temperature of your house should be no more than 68 degrees to save money on your utility bills. If this seems too cold for you, you could start at a comfortable temperature and then adjust the thermostat one degree each week.
2. A Good Temperature for When You’re Away in the Winter
When you’re away, you can safely set your temperature to 60 degrees. To protect your pipes from freezing and eventually bursting, keep the temperature higher than 55 degrees at all times.
Before going to bed, you should also lower the temperature to 62 degrees. A colder environment helps you sleep better, but if you prefer warmth, you could bundle up in blankets, socks and sweatshirts until your body adjusts.
3. Energy Savings in the Winter
If your home is at a comfortable temperature, it shouldn’t matter whether you’re in a blizzard or it’s a warm day in winter. However, the outside air may affect your interior living environment if your home isn’t completely energy efficient. You can follow these money-saving tips to keep your thermostat low:
- Invest in energy-efficient windows that keep out cold air and bring in natural sunlight.
- Weatherstrip around the windows and doors and check for drafts throughout the house.
- Inspect the insulation throughout your house and consider reapplying it where necessary.
- Hang up heavy, full-length curtains to guard against cold drafts.
- Never use cooking appliances as alternative heating sources in your house.
- Rotate your fans to spin clockwise to circulate the hot air from your furnace throughout the house.
How to Create Home Comfort All Year Long
An energy-efficient HVAC system could help you save money throughout the year. To have a comfortable temperature in the summer and winter, check out these other tips:
- Control the humidity: If you use a dehumidifier throughout the year, you won’t have to run the HVAC system as often. Our MRCOOL products feature a dehumidifying mode to pull the moisture from the air, even when you’re not cooling or warming the house.
- Set up a zoning system: Zoning is a method of heating and cooling sections of your house at a time. The MRCOOL® DIY® Multi-Zone heating and cooling system allows you to control the temperature of more than one room at once.
- Dress appropriately: In the cold weather, wear a few extra layers and drink some hot tea to keep yourself warm instead of adjusting your thermostat. Over the summer, wear shorts and a tank top around the house to beat the heat. Eventually, your body adjusts to the temperature you set on the thermostat.
- Keep your HVAC system maintained: To prolong the integrity of your HVAC system, you should have the unit checked once a year. Replace the filters and clean out the vents in the spring and fall to prepare for the summer and winter.
- Upgrade to a programmable thermostat: This type of thermostat allows you to set the temperature of your house in advance, so it automatically adjusts depending on the time of day and when you need it most.
