Mini Split Sizing Guide

Mini Split Sizing: The Ultimate Guide

Hi there, my name is Russ, and I’m one of the managers at Reliable Appliance & HVAC. If you’re reading this, you might be wondering about Mini Split Sizing, right? Well, you’ve come to the right place! In this comprehensive guide, we’re going to walk you through everything you need to know about Mini Split Sizing.

But before we dive into the nitty-gritty, let me tell you about a recent job we handled. It was from John Smith of Pasadena, California. He called us because his central AC wasn’t performing well. As our technician diagnosed the issue, he realized that the air conditioning unit was too big for his house, which was causing uneven cooling, high electricity bills, and other problems.

Our team quickly suggested installing a Mini Split AC, which then brought out various questions about how to size a Mini Split for John’s specific needs. With an efficient Mini Split system, John finally managed to cool his residence perfectly without spending a lot on power.

Now that you’re aware of what occurred with John, let’s talk Mini Splits.

What Is Mini Split Sizing?

Mini Split Sizing is how specialists determine the best size of an AC to fit in your house. An undersized Mini Split won’t cool your home efficiently, while an oversized one will end up cooling the air but only at a specific area, and that will make the motor work even harder, disrupt the motor’s lifespan, and increase your electricity expenses. Therefore, getting the perfect Mini Split size is crucial for your comfort and your finances.

Factors To Consider When Choosing The Right Size Mini Split

Here are some significant factors to consider when selecting the perfect sized Mini Split for your residence:
– The size and layout of your house
– Your local climate
– The number of people living in the home
– The level of natural light that the house receives
– The level of insulation

How To Determine The Right Mini Split Size For Your Home?

To decide the right Mini Split size for your house, you should calculate the square footage (sqft) of the area you want to cool. Afterward, find the BTU capacity required to get the Mini Split doing what it is advertized for. As a word of caution, it’s essential to hire an experienced technician, such as ours at Reliable Appliance & HVAC, to get the right Mini Split size and capacity.

Case Study: How We Helped John Smith from Pasadena

John was struggling to determine the correct Mini Split size for his reasonably furnished 3-bedroom apartment with two bathrooms. Firstly, our technician conducted a thorough inspection of the residence, including a comprehensive heat load calculation, which determined the required BTU sizing.

Based on the BTU sizing required, our technicians suggested that John invests in a 24,000 BTU Mini Split. Afterward, we prepared and sent John an efficient and budget-friendly quote that consisted of part, material, and labor costs. John was delighted with the quote, and we did an excellent job installing his Mini Split.

Mini Split Sizing Table:

Below is the table of the parts, materials, and labor cost alongside the total cost. As you can see, the cost was affordable for John, and he didn’t have to pay any hidden charges.

Part/Material/Labor Brand Quantity Price ($) Total Cost ($)
24,000 BTU Mini Split Customer 1 1,000 1,000
Copper Lineset 1 200 200
Electrical Wire 1 100 100
Installation Labor 1 700 700
Total 2,000


As you can see, Mini Split Sizing isn’t something you should take lightly. To ensure that you get the most effective and efficient AC, you must choose the correct size. If you’re unsure what size to get, feel free to reach out to us at Reliable Appliance & HVAC, and we will be happy to assist you.

Thanks for reading, and happy cooling!
