MRCOOL has become a go-to brand for homeowners seeking affordable, efficient, and easy-to-install heating and cooling solutions. Known for their pioneering DIY mini split line, MRCOOL systems allow customers to install pre-charged, easy-fit lines themselves—offering significant savings on installation costs without sacrificing quality. This guide covers everything you need to know about MRCOOL mini splits, from efficiency and coverage to heating capabilities, lifespan, comparisons with other brands, and where to buy.
Why Choose a MRCOOL Mini Split System?
Affordable and DIY-Friendly Climate Control
MRCOOL is a Kentucky-based brand with an affordable line of mini splits, perhaps most well known for their DIY line, allowing customers to install pre-charged, easy-fit lines, making for huge installation cost savings.
Multi-Zone and Single-Zone Flexibility
The brand’s units are easy to scale. Like all mini split makes and models, MRCOOL mini split multi-zone units allow homeowners to add several handlers to a single outside unit, depending on the climate control needs of their home over time.
No Ductwork Required for Installation
The units also offer individual climate control throughout a home by remote. MRCOOL mini split installation is simple (read: no ductwork) and sometimes DIY-friendly based on the model, too.
How Efficient Is a MRCOOL Mini Split?
Understanding SEER Ratings and Energy Savings
MRCOOL mini split systems rely on state-of-the-art manufacturing processes and advanced design to deliver high-efficiency air comfort anywhere you need it. Mini split systems offer SEER-rated AC from 16 SEER and up, efficient enough to qualify for rebates as replacement units in many cases.
MRCOOL Mini Split Coverage Area
Choosing the Right Size for Your Home
The scalable element of mini split units makes them excellent candidates for nearly any size home. A single handler hooked up to an outside unit can easily cool a studio apartment. If you have a larger home, you can add more handlers. For instance, a 3,000 sq ft home would probably require five or six handlers in optimum positions. If you're having trouble with sizing, try reading our mini split sizing guide for help.
Wall-Mounted vs. Floor-Mounted Units
Firect, consider your home’s size and layout or that of the space you are looking to heat or cool. From there, choose from single-zone or multi-zone mini split A/C units. Keep in mind that wall-mounted A/C mini-splits as well as floor models are available. This gives the option to position units in the best locations to cool or heat a space based on its shape, height, adjoining rooms, and so on.
Heating Performance of MRCOOL Mini Splits
MRCOOL Heat Pumps for Year-Round Comfort
Along with manufacturing accessible, high-quality cold air units, MRCOOL can provide a reliable heating function with its line of sophisticated, state-of-the-art heat pumps. These function as a perfect complement to the brand’s cooling systems, particularly in climates that suffer from the full brunt of hot and cold weather throughout the year.
How Does a MRCOOL Heat Pump Work?
Summer Cooling Mode
In the summer, refrigerant is compressed and circulated through a system of coils that withdraws heat from the home and expels it outside. The system does not directly produce cold air, but when warm air is removed, cold air rushes into the void to replace it.
Winter Heating Mode
In the winter, the roles of the coils are reversed. Instead of removing heat from the home, heat is extracted from the atmosphere outside. Once captured, it is forced inside while the cold air is withdrawn.
Dual-Purpose Climate Control Technology
Mini split heat pumps differ slightly from traditional heat pumps. Rather than operate with a single function, innovative mini split units, like those that MRCOOL offers, are equipped to reverse not only the role of the refrigerant but the function of the evaporator and condenser coils, too. This gives a mini split outfitted with a heat pump a unique dual-purpose ability that can provide year-round climate control.
Can MRCOOL Heat a Whole House?
MRCOOL mini split systems equipped with a properly-sized heat pump can heat a whole house in most regions of the country. It is important to determine just how low an outside temperature each model will perform at, as each model may have different specs. A heat pump can work marvels even if your home is in an extreme northern winter temperatures. However, the unit might need a little help from an electric coil furnace or gas furnace on particularly cold days.
MRCOOL Mini Split Lifespan and Warranty
Expected Years of Reliable Service
Mini split systems are durable units. You can count on at least 10 years of operation. Heat pumps often last well into their 20s, too.
What the MRCOOL Warranty Covers
The MRCOOL warranty is 5 years on most models, with a 7-year compressor clause.
MRCOOL vs. Other DIY Mini Split Brands
Competing Brands Offering DIY Installation
While MRCOOL is an excellent DIY mini split brand, there are plenty of good mini split brands on the market. At HVACDirect.com, we feature a wide selection of both units and brands. Those who offer DIY compatible systems include market leaders like ACiQ, Perfect Aire, and, of course, MRCOOL.
What Sets MRCOOL Apart
The major point of the MRCOOL brand is affordability and the availability of the DIY line.
MRCOOL vs. Mitsubishi Mini Splits
Comparing Efficiency and Features
Mitsubishi systems are very impressive mini split units. They come with 10-year warranties and high SEER ratings. (I.e., they’re very efficient.) However, MRCOOL systems easily match many of the same basic specs — at a lower price point than other, premier brands.
Are MRCOOL Systems Worth the Investment?
As with most home improvements, the true answer to the question of which one is right for you depends on multiple factors. From your budget to your priorities, consider what factors are driving your mini split upgrade.
Are you trying to improve your home, but you want to sell in a year or two? In that case, you may want to invest in a minimal setup, with a single outside unit and a handler or two to cool key parts of your home. If you’re in your living space for the long haul, a full MRCOOL system can be a great long-term option.
Whatever your circumstances, if you’re unsure which product is right for you, you don’t have to figure it out on your own. You can call or instant-chat with our friendly, knowledgeable staff. Our crew is available seven days a week to answer your questions. No one works on commission here, so you won’t get any hard sells or upselling, either — just the facts backed by genuine, trained HVAC technicians.

What Is a Heat Pump and How Does It Work?
Heat pumps are receiving a lot of attention lately due to their ability to heat homes through electricity, which is much easier to produce sustainably than traditional heating fuels. In essence, a heat pump is an air conditioner that operates in reverse.
In the summer, refrigerant is compressed and circulated through a system of coils that withdraws heat from the home and expels it outside. The system does not directly produce cold air, but when warm air is removed, cold air rushes into the void to replace it.
In the winter, the roles of the coils are reversed. Instead of removing heat from the home, heat is extracted from the atmosphere outside. Once captured, it is forced inside while the cold air is withdrawn.
