What is a Mini Split and How Does It Work?
If you’ve been looking for a flexible and efficient way to manage your home’s temperature, you’ve likely come across the term “mini-split.” So, what exactly is it? Simply put, a mini-split is a ductless system that acts as both an air conditioner and a heater. It’s also known as an air-to-air heat pump because it doesn’t create heat—it moves it. In the summer, it pulls heat from inside your home and transfers it outdoors. In the winter, it reverses the process, extracting heat from the outside air (even when it’s cold) and bringing it inside to warm your space.
This dual-purpose design makes it an incredibly versatile solution for year-round comfort. Unlike traditional central air systems that rely on a network of ducts to distribute air, a mini-split system delivers it directly into different zones or rooms. This ductless approach is a game-changer, especially for homes without existing ductwork or for new additions where extending ducts would be costly and complicated. It offers a streamlined way to get powerful cooling in the summer and effective heating in the winter, all from a single, energy-efficient unit.
Your Mini Split's Main Components
A mini-split system has two primary parts that work together. First is the outdoor unit, which contains the compressor and condenser. Think of this as the engine of the system; it’s where the heat exchange happens. The second part is the indoor unit, or air handler. This is the sleek, wall-mounted unit you see inside your home that quietly distributes the cool or warm air.
These two components are connected by a small conduit that runs through a three-inch hole in an exterior wall. This conduit houses the power cable, refrigerant lines, and a condensate drain. Because you can connect multiple indoor units to a single outdoor unit, you can create customized temperature zones throughout your home, giving you precise control over your comfort.
Mini Splits vs. Traditional HVAC: What's the Difference?
The biggest difference between a mini-split and a traditional HVAC system is the absence of ducts. Central systems push air through a large network of ducts, which can lose up to 30% of their energy through leaks, holes, and poor connections. Mini-splits are ductless, delivering air directly into a room, which makes them significantly more efficient.
Another key advantage is zoned comfort. With a mini-split, each indoor unit has its own thermostat, allowing you to cool or heat specific areas independently. You can keep your bedroom cool at night without wasting energy on the rest of the house. Traditional systems, on the other hand, typically use one central thermostat, making it difficult to manage temperature differences across your home.
Why Mini Splits Are Perfect for Okanagan Homes
The Okanagan’s four-season climate, with its hot summers and chilly winters, makes a mini-split an ideal home comfort solution. Their ability to provide both high-efficiency air conditioning and heating from one unit is a perfect match for our weather swings. Many older homes in Kelowna, Vernon, and Penticton were built without ductwork, making mini-splits a fantastic, non-invasive upgrade.
They are also incredibly flexible. Whether you’re building a new home, adding an extension, or just want to solve a stubborn hot or cold spot, a mini-split can be tailored to your needs. This ability to provide zoned cooling and heating not only keeps everyone comfortable but also helps you manage high energy costs by only using what you need, where you need it.
What to Expect During a Professional Installation
A mini split AC unit installation is more than just hanging a box on the wall. It’s a precise process that ensures your system runs efficiently, safely, and reliably for years. While it might seem straightforward, several key steps require certified expertise to protect your home and your new equipment’s warranty. Think of this as a behind-the-scenes look at what our technicians do to guarantee your comfort.
From the moment we arrive, our goal is to make the installation smooth and transparent. Our team of NATE-certified HVAC technicians follows a meticulous process designed to get every detail right. We’ll walk you through the plan, answer your questions, and treat your home with respect. Here’s a step-by-step breakdown of what you can expect when TruFinity installs your new ductless mini-split.
Step 1: Assessing Your Space and Sizing the System
The first and most important step is making sure you get the right-sized unit. A system that’s too small will struggle to cool your space, while one that’s too large will cycle on and off too frequently, wasting energy and failing to dehumidify properly. To avoid this, our technicians perform "Proper sizing calculations using Manual J load calculations." This is the industry standard for accurately determining your home's specific heating and cooling needs by analyzing factors like square footage, window placement, insulation, and local Okanagan climate patterns. This detailed assessment ensures your new system is perfectly tailored to your home for maximum efficiency and comfort.
Step 2: Placing the Indoor and Outdoor Units
Once we’ve sized the system, we’ll work with you to determine the best placement for both the indoor and outdoor units. The indoor unit is typically mounted high on an exterior wall, about seven feet from the floor, to allow for optimal air circulation. We’ll help you choose a spot that is both effective and aesthetically pleasing. The outdoor condenser unit needs to be placed on a solid, level surface, like a concrete pad, with plenty of clearance for airflow and service access. Proper placement is key to quiet operation and the long-term health of your system.
Step 3: Connecting the Refrigerant Lines
With the units in place, it’s time to connect them. Our technicians will drill a small, clean hole (about 2.5 inches) through the exterior wall to run a bundle of lines between the two components. This line set includes copper tubing for refrigerant, electrical wiring for power and communication, and a condensate drain line. Creating a perfect, leak-proof seal on the refrigerant lines is critical and requires specialized tools and training. We use professional-grade equipment and techniques to ensure every connection is secure, preventing refrigerant leaks that could harm your system and the environment.
Step 4: Powering Up and Final Checks
This is where everything comes together. Before charging the system with refrigerant, our technicians perform a pressure test with nitrogen to confirm there are absolutely no leaks in the lineset. Next, we use a vacuum pump to remove all air and moisture from the copper lines, which is essential for efficient operation. Only then is the system charged with the precise amount of refrigerant specified by the manufacturer. This step is strictly regulated, and our team uses "Vacuum recovery systems for refrigerant handling per EPA requirements," ensuring every installation is safe and compliant.
Step 5: Ensuring Everything is Safe and Up to Code
Your safety and peace of mind are our top priorities. A professional installation guarantees that all electrical work is done correctly and meets local codes here in the Okanagan. It also protects your investment. Most manufacturers require installation by a licensed professional to keep the warranty valid, and our team receives "Manufacturer training ensuring warranty validity." As a Daikin Comfort Pro dealer, we follow the highest standards to make sure your system is installed perfectly. We’ll walk you through the new system’s operation, explain the remote control, and answer any final questions you have.
Should You Install It Yourself or Hire a Pro?
The appeal of a DIY project is strong, especially when you see a seemingly straightforward installation video online. While tackling home improvement projects can be rewarding, a mini-split installation is one of those jobs where the risks often outweigh the savings. It involves electrical wiring, specialized tools, and the handling of controlled substances. Before you decide to take it on yourself, let’s break down what’s really involved.
The DIY Route: What You Can (and Can't) Do
Some parts of a mini-split installation, like mounting the brackets for the indoor and outdoor units, might seem within reach for a handy homeowner. However, the project quickly moves into tasks that require professional expertise. The most critical steps—high-voltage electrical connections and managing the refrigerant lines—are complex and carry significant risks. An improper electrical hookup is a serious fire hazard, while a mistake with the refrigerant lines can ruin your new system before it ever cools your home. These are jobs best left to a licensed and insured technician.
Tools and Equipment Needed for the Job
A successful mini-split installation requires more than just a drill and a level. A professional’s toolkit includes highly specialized equipment that isn't typically found in a home garage. This includes a vacuum pump to remove moisture from the lines, a torque wrench to tighten flare nuts to exact specifications, a nitrogen tank for pressure testing, and a micron gauge for precision measurements. Sourcing these tools can be costly and complicated for a one-time project. Our NATE-certified HVAC technicians arrive fully equipped to ensure every connection is perfect.
Why Refrigerant Handling Requires a Certified Pro
Refrigerant is a chemical that is strictly regulated by the government for environmental and safety reasons. Handling it without the proper certification is illegal. A professional installation involves using a vacuum pump to purge the lines of any contaminants, pressure testing the system with nitrogen to check for microscopic leaks, and charging it with the exact amount of refrigerant required. At TruFinity, our team uses proper "vacuum recovery systems for refrigerant handling per EPA requirements," guaranteeing your system is installed safely, legally, and is set up for optimal performance.
Protecting Your Warranty and Insurance
Nearly every mini-split manufacturer requires the unit to be installed by a licensed HVAC professional for the warranty to be valid. If you install it yourself and something goes wrong, you could be responsible for the full cost of repairs or even a full replacement. Our technicians receive specific "manufacturer training ensuring warranty validity," so your investment is protected. A professional installation also ensures the work complies with local building codes, which is essential for your home insurance coverage and your family’s safety.

5 Common Installation Mistakes to Avoid
A mini-split installation might look straightforward on video, but it’s a technical job where small mistakes can lead to big problems. Getting it right the first time saves you from future headaches, inefficient performance, and costly repairs. An incorrect installation can even void your manufacturer's warranty, leaving you without coverage when you need it most. At TruFinity, our NATE-certified technicians have seen it all, and we’ve fixed our share of installations that didn't go as planned. To help you understand what a quality installation involves, here are five common mistakes we see and how a professional approach prevents them, ensuring your system runs perfectly for years to come.
Mistake 1: Choosing the Wrong Size
It’s easy to think bigger is better, but when it comes to a mini-split, size is everything. An oversized unit will cool the room too quickly without properly dehumidifying the air, leaving you with a cold, clammy feeling. It will also cycle on and off constantly, wasting energy and wearing out components faster. A unit that’s too small will run nonstop, struggling to keep up on hot Okanagan summer days and driving up your energy bills. That’s why our technicians perform precise Manual J load calculations to find the perfect fit for your space, considering factors like square footage, insulation, window placement, and local climate.
Mistake 2: Placing Units in the Wrong Spot
Where you put the indoor and outdoor units matters just as much as the size. The indoor unit needs to be placed high on a wall where it can distribute air evenly throughout the room without creating uncomfortable drafts. It also needs a clear path for the drainage line. The outdoor condenser needs to be in a stable, level spot with plenty of clearance for airflow and service access. We always consider factors like noise, aesthetics, and proximity to the indoor unit to find the optimal location. A poorly placed unit can lead to poor performance, water damage from improper drainage, or even just be an eyesore.
Mistake 3: Creating Refrigerant Leaks
Connecting the refrigerant lineset between the indoor and outdoor units is one of the most critical steps—and the easiest to get wrong. These copper lines require special flaring tools and a torque wrench to create a perfect, leak-proof seal. Even a tiny leak can let the refrigerant escape, which is harmful to the environment and will cause your system to lose its cooling and heating power. Our EPA-certified technicians are trained to handle refrigerants safely and use vacuum recovery systems to ensure the lines are clean, dry, and perfectly sealed according to manufacturer specifications. This protects your system’s efficiency and the planet.
Mistake 4: Skipping Essential Safety Tests
Once everything is connected, a professional installer doesn’t just turn the system on and call it a day. We perform a series of crucial tests to guarantee the installation is safe and secure. This includes a pressure test, where we fill the lines with inert nitrogen to a high pressure to confirm there are absolutely no leaks in the system. We also perform a vacuum pull to remove all moisture and air from the lines before releasing the refrigerant. Skipping these steps is a major red flag and can lead to system failure down the road. Our process is part of our commitment to "True Service, Infinite Care."
Mistake 5: Ignoring Proper Drainage
Both the indoor and outdoor units produce condensation that needs to drain away properly. For the indoor unit, the drain line must have a consistent downward slope to prevent water from backing up and causing leaks inside your home. For the outdoor unit, especially during the heating cycle in our cold Okanagan winters, proper drainage is vital. We ensure the unit is elevated off the ground—at least 8 inches above the expected snowfall—so that melting ice and water can drain freely without freezing up and damaging the unit. This simple step is crucial for year-round reliability.
After Installation: Testing and Maintaining Your Mini Split
Once your new mini split is installed, the work isn’t quite finished. The final steps are all about commissioning and testing to ensure your system runs flawlessly for years to come. This is where a professional touch makes all the difference, turning a good installation into a great one. It’s also the perfect time to learn how you can keep your system in top shape. At TruFinity, we believe in setting you up for success, which means walking you through the final checks and your simple maintenance routine.
Our goal is to leave you with a perfectly running system and the confidence to keep it that way. We’ll make sure every connection is secure, every setting is optimized, and you know exactly what to expect from your new high-efficiency unit. This final phase is a core part of our "True Service, Infinite Care" promise, ensuring your comfort and peace of mind from day one.
The Final Check: Our 25-Point Inspection
Before we pack up our tools, our NATE-certified technicians perform a comprehensive 25-Point HVAC System Inspection. This isn't just a quick once-over; it's a detailed commissioning process to verify that every component of your mini split installation meets our high standards and the manufacturer's specifications. We check everything from the electrical connections and refrigerant levels to the condensate drain line and thermostat communication. This meticulous process guarantees your system operates safely, efficiently, and reliably, giving you the performance you paid for and protecting your warranty.
Testing Your System's Performance
A critical part of our final check involves rigorous performance testing. Our technicians use specialized equipment to conduct a pressure test on the refrigerant lines, ensuring there are absolutely no leaks that could compromise efficiency or harm the environment. We then use a vacuum pump to remove all air and moisture from the lines—a crucial step that prevents internal corrosion and ensures the longevity of your system. Finally, we run your mini split through its full range of heating and cooling cycles to confirm it delivers consistent, comfortable air and responds correctly to the thermostat.
Your Simple Maintenance Checklist
Your mini split is a low-maintenance machine, but a little care goes a long way in keeping it efficient. Here’s what you can do:
- Clean the Filters Monthly: The indoor unit has a reusable filter that slides out easily. Just rinse it with water, let it dry, and pop it back in. This simple task keeps your air quality high and your system from working too hard.
- Keep the Outdoor Unit Clear: Make sure the area around your outdoor condenser is free of leaves, grass clippings, and debris. In the winter, gently brush away any snow accumulation to ensure proper airflow.
