6 Best 24000 BTU Mini Splits Reviews 2022

Ductless mini-splits are an excellent way to cut down your power consumption without sacrificing the comfort of your home or office. However, it’s vital to match your mini split with the size of the rooms you want to cool or heat.

A 24000 BTU mini-split is an excellent heating and cooling solution for most average homes and office spaces with rooms ranging between 800 to 1200 Sq, without the need for ductwork. 

Here are 2021’s Best 24000 mini-splits worth buying to manage your indoor temperature while reducing your energy costs all year long. 

When Would I Need A Ductless Mini-Split Air Conditioner?

Ductless mini splits have continued growing in popularity over the last decade and for good reasons.

Here are a few circumstances when a ductless mini-split is the ideal air conditioning system for your home. 

When there’s No Ductwork

Traditional duct air conditioning system requires a lot of work in the house design to install. However, when you’ve got no ductwork in your house, you can still enjoy a comfortable indoor temperature in your house.

Ductless air conditioning systems require no ductwork in your house, and they allow you to warm or cool any broom in your house. That means they’re easy to install within hours, and there no need for major renovation works to fit in the ducts. 

When Silence is Crucial

Unlike traditional systems that make loud rattling noises, ductless mini splits are great for rooms that value silence, ranging from your bedroom to your study room.

The quietest mini split air conditioners even feature a noise reduction option that reduces the sound level to about 20 decibels. That ensures you get some peace while controlling your room’s temperature. 

Great for Small Rooms

While sizing is crucial when choosing an air conditioning system for your room, ductless mini splits are the perfect solution for small rooms without any space for ductwork. These systems are also energy-efficient, allowing you to pay for electricity bills only for the rooms in use. 

When you need to Control the Temperature of Each Room Independently

With each room having an independent indoor air handler, you can personalize each room’s indoor temperature according to your needs. That means you can make some rooms warmer and others cooler, even with a single outdoor unit. 

Pros And Cons Of Ductless Mini Split Systems

There’s no doubt that ductless mini-splits add more value to your house, whether you’re looking to resell or not. However, like any other equipment, installing a ductless mini-split comes with different pros and cons, including:

Pros of Installing a Ductless Air Conditioner

  • Quiet – With the compressor unit set outside your house, the only audible noise comes from your indoor system. Additionally, some ductless systems are designed with silence in mind, featuring advanced noise reduction features for an ultra-quiet operation. 
  • No Ductwork Needed – You’ll not have to worry about the time-consuming work of setting up ducts, which can also spread allergens and other toxic particles around your house. 
  • Efficient – Unlike window air conditioning systems, ductless mini-splits can cool and warm your house all year. That includes the versatile option of setting the temperature in each room while minimizing the energy lost. In fact, ductless systems reduce up to 30% of energy than the traditional duct system. 
  • Energy-Saving Technology – Ductless mini splits feature responsive technology that’s energy-efficient, unlike other air conditioning systems. This technology cuts down the energy loss during startups and conserves energy in the long run. 
  • Flexible Installation Options – Ductless mini-splits come in various sizes and shapes to complement your space and offer comfort in the best possible way. You can choose from wall-mounted systems to ceiling cassette units designed with form and function in mind. 
  • Healthier Air – Most mini-split brands include air filters as a standard feature in their systems, circulating clean air free from mold, dust, bacteria, and allergens that might otherwise get sucked into a traditional ductwork system. 
  • Zone Temperature Control – Ductless mini-splits let you independently control the temperature of each room individually. For instance, you can switch off your bedroom’s AC until it’s time for bed. That ensures you don’t waste any energy on rooms, not in use. 

Cons of Installing a Ductless Air Conditioner

  • Might be Costly – The up-front price to replace your conventional HVAC system might be a bit higher. While you’ll see a decrease in your electricity bills, it will take years before the system can pay off itself through the savings. 
  • Need Regular Maintenance – ductless mini-splits can’t function well with dirty air filters, so regular maintenance is required.   

How Many Square Feet Will 24000 Btu Cool?

According to the Environmental Protection Agency, most homeowners make the mistake of buying air conditioners too large for their spaces, resulting in increased energy waste and a rise in air conditioning costs.

You can control a small room temperature using a 5000-1000 BTU system, but large rooms will need a system that packs 24,000 BTUs or more. 

With 24000 BTU mini-splits, you can effectively warm a room ranging from 1400-1500 square feet in size. However, multi-zone 24000 BTU mini splits can support up to four small rooms, although the configuration may vary.

For instance, with a dual-zone 24K BTU mini-split, you’ll get two indoor air handlers with 12000 BTU each. 

What Breaker Size Do You Need For A 24000 BTU Mini Split?

When installing a ductless air conditioning system, you’ll need a breaker that can handle the amps that your unit is rated for. That’s because mini-splits need dedicated circuitry for the power supply.

You’re also required by code to install a disconnect box close to the outdoor compressor unit. The disconnect box also ensures the technician can easily shut off the power for services and repairs.

With a breaker labeled 20, it means it can deliver 20 amps to your outdoor compressor system. However, 24000 BTU mini-splits require a 25 amps breaker size to control your room’s temperature efficiently. As such, you might need to consider electrician costs when thinking of installation.

How Many Watts Does A 24000 Btu Mini Split Use?

While 24000 BTU mini splits are efficient in heating large rooms, they typically require more energy. Such a system will need 3000-4000 watts, although the insulation of your room and where you’re located might also come into play. As such, the average 24K BTU system requires about 6-7 kWh to operate effectively. 

How Much Does It Cost To Install Mini-Split Systems?

The cost of installing a ductless mini-split may vary depending on your location, but you can expect to pay around $5000 per zone.

That means budgeting on a total range of anywhere between $5000 and $20000. Fortunately, common single-zone mini splits are in the lower end of this price range. 

This price range features many cost listings that most HVAC experts leave out of their online quotes, but they’re necessary for the installation.

Remember that installation might get complicated, with costs involving buying specialized tools and equipment, flammable materials, and other stuff. These costs might run into thousands of dollars depending on which system you’re installing.

How To Use Mini-Splits Efficiently

Apart from investing in an energy-efficient mini-split system, here are a few smart tips to maximize the efficiency of your mini-split.

  • Set your comfort – since the temperature sensor on your system is closer to the ceiling where the air is hotter, you might need to adjust the temperature slightly higher to deliver the desired comfort. 
  • Don’t touch the dial – After setting a comfortable temperature, keep your fan on Auto and set the unit on Cool during the summer and heat in the winter. That lets your mini-split maximize efficiency by powering up only when necessary. 
  • Regular maintenance – a mini-split that’s not regularly maintained increases its power usage by up to 25%. That’s why regular cleaning of the air filters is required to keep the snow, ice, and debris away.
