What Is a Mini Split System?
A mini-split system is a heating and cooling option that regulates temperature only in a few areas of the house. On the other hand, unlike a central HVAC unit which forces air through ducts to heat or cool the entire house, it consists of one external compressor linked to several indoor air handling units.
Flexible and Efficient
-
The greatest thing about mini splits is that each indoor unit has its thermostat which means you can comfortably create different temperatures in various rooms. Mini-splits are also very economical with energy since there is no energy lost while transferring air via ducts. The direct refrigerant lines are sealed which ensures optimal heat transfer.
Types of Mini Splits
-
There are two main categories of mini-splits: single-zone and multi-zone. A single-zone mini split has one outdoor unit connected to one indoor unit, which is perfect for heating and cooling in just one space such as an addition or in-law suite. Conversely, a multi-zone mini split entails one outdoor unit connected to multiple indoor units so you can heat and cool multiple spaces separately. Such systems are ideal for homes up to 700 square feet in size.

Factors to Consider When Choosing a Mini Split for 700 Sq Ft
Size
For 700 square feet, you'll want a mini split that can properly heat and cool the space. As a rule of thumb, you'll need around 1 ton of cooling for every 400 to 600 square feet. That puts you right in the sweet spot for a 1.5-ton or 2-ton unit. Either of these sizes should work great for a 700-square-foot area.
Efficiency
Look for an Energy Star-rated mini split with a high SEER (Seasonal Energy Efficiency Ratio) rating, at least 15 or higher. The higher the rating, the more energy efficient the unit is, saving you money. Some of the most efficient models today can reach SEER ratings of 22 or more.
Heating and Cooling Needs
Consider how you'll use the mini split. If you need it primarily for cooling, look for a model geared toward higher efficiency in cooling mode. If you need heat more often, choose a unit with a high HSPF (Heating Seasonal Performance Factor) rating and multiple heating stages for the best comfort. The most versatile units will perform well in both heating and cooling modes.
Installation Requirements
Make sure you understand what's involved with installing a mini split in your home. Most require mounting the condenser outside, in a location with plenty of airflow, and the evaporator inside the space you want to heat and cool. Consider any obstacles to running the refrigerant lines between the two units and the electrical requirements. Choosing a unit that doesn't require major modifications to install will save you time, money, and hassle.

Installation Tips for Your New Mini Split
Installing a mini-split system yourself is doable for handy homeowners, but also consider hiring an HVAC professional to ensure it’s done properly. Either way, here are some tips to keep in mind.
Choose an optimal location
-
Find a spot on your wall that will allow the indoor unit to efficiently heat or cool the space. It should be up high, near the ceiling, and in an area with good airflow. Make sure no obstacles are blocking the vents. The outdoor unit will also need an area outside with plenty of air circulation, like near ground level on the side of the house.
Ensure proper drainage
-
If you live in a rainy or humid climate, install the outdoor unit on a concrete pad with a slight angle so water can drain properly. This will prevent water from pooling underneath, which could damage the unit over time. You'll also want to direct the water drain line that extends from the indoor unit to flow to an appropriate drain.
Consider the wiring
-
The units will require a power supply, as well as wiring to connect the indoor and outdoor units. Have an electrician install a dedicated circuit and wiring for your mini split to ensure it has enough power and avoid overloading your electrical system. They can also connect the communication cable between the units so they work in tandem.
Brace the wall mount
-
Secure the wall mount for the indoor unit to wall studs or beams to provide stability. The mount will need to support the weight of the unit, so wall anchors alone may not be enough. Install additional bracing between wall studs or choose a sturdier mount rated to handle the recommended weight. This helps prevent the unit from loosening or detaching from the wall over time.
Test and seal any leaks
-
Once installation is complete, test your mini split to ensure it's running properly and cooling or heating as expected. This also allows you to check for any air leaks or refrigerant leaks and seal them before putting the system into use. An HVAC pro can perform pressure tests to check for and address any leaks. Your mini-split is now ready to keep your space comfortable!
