So, you want to add a mini-split to your Houston home. You’re not the first and you won’t be the last. 

Ductless mini-splits are a great way to heat your home in the winter and cool your home in the summer. They’re a cost-effective HVAC system, plus they’re efficient and versatile. It’s no surprise that they’re a popular option for Houston homeowners.

If you’re considering a mini-split, you’ve probably got some questions about how much their installation costs, how to get it done, and what the best A/C unit you can get is.


Well, we’re here to share everything you need to know about the cost of installing a ductless mini-split.

How Much Does it Cost to Install a Mini-Split?

The cost of installation is often the first question on somebody’s mind when it comes to any home renovations or upgrades. The benefit of ductless mini-splits is they can have a low installation cost, while also lowering your power bills once they’re up and running.

The cost to install a mini-split system can be anywhere from $2000 to $15,000. We know, it’s quite a range. The truth is, the installation cost is going to depend on: 

The Size of the Unit

The size of the unit you’re installing will depend on the size of your home. The average ductless mini-split air conditioning system works well in a 2500-3000-square foot home. Generally, costs can range from $3000 to $9000 for these.

On the contrary, something a bit smaller (12,000 BTU – which is how the cooling capabilities are measured) would fit a 400-square foot space best. You can also purchase additional indoor units for individual rooms for $400 – $1800 each.

What Brand You Opt For

Brands known for quality are often going to cost you more – but it won’t be for nothing. At Nick’s Air Conditioning and Heating, we are a Mitsubishi Diamond Certified service provider and we install Mitsubishi indoor air handlers that are perfect for Houston. 

Mitsubishi has great all-around options for ductless mini-split systems, as they range in size to accommodate everything from small residential areas to enormous commercial spaces. Check out our Mitsubishi product guide to see which HVAC option is right for your space.

The SEER Rating

SEER stands for “seasonal energy efficiency rating.” Basically, HVAC units with a higher SEER rating operate more efficiently. A more efficient system will save you money in the long run, as your monthly utility bill can drop and save you some coin.

SEER ratings are important to consider, especially with the announcement of the newest SEER 2023 regulations.

Is Installing a Mini-Split Worth the Cost?

Have you ever been through a Houston heat wave? Have you ever spent the day hiding from the sun and wishing it was cooler inside your home? The comfort an AC unit can add to your home is unmatched – so yes, we say a mini-split air conditioner is worth the investment. 

Ductless mini-split air conditioning systems are an easy installation for an experienced HVAC company like ourselves, and the installation costs less than a central air conditioning installation.

And for all the people out there who run hot or cold – you’ll be glad to know that mini-split systems allow for room-by-room temperature control. No more fighting over the thermostat.

We’ve highlighted some great advantages, but if you need more convincing, there are many more reasons why you should install a mini-split air conditioner.

Can I Install a Mini-Split Myself?

Are you trained in HVAC? If not, then we’d caution against DIY-ing it. A mini-split AC installation should be left to the pros. An improper HVAC installation can lead to major expenses down the line. Take for instance, if you end up with a leak in your unit, you could be paying exorbitant energy costs… without the benefit of actually cooling or heating your home. Not to mention working with electricity is dangerous.

We’re also trained in HVAC maintenance, and have a VIP HVAC maintenance plan that’ll save you on maintenance costs throughout the year, and ensure your unit is running smoothly. So don’t attempt to install or fix your mini-split yourself, you may end up calling us anyway.
