TL;DR
The “best price” MrCool mini-split usually isn’t the lowest sticker price — it’s the lowest total cost for a complete, correctly sized kit that matches your voltage and avoids surprise add-ons. Start by confirming BTU sizing and whether you need 115V or 230V power, then compare only apples-to-apples kits with the same line-set length and included accessories.

Top Pick: Best Overall Heating & Cooling
MRCOOL 12000 BTU 115V DIY Mini Split Heat Pump System
Best for: A homeowner cooling and heating a single room or small zone (like a finished garage, bonus room, or addition) who has 115V power available and wants the best shot at a low total installed cost by doing most of the work themselves.
The Good
- DIY-friendly positioning: homeowner reports frequently frame this as “involved but manageable” when you can handle mounting, drilling, and careful routing.
- All-in-one value logic: for many shoppers, the biggest “price win” is avoiding labor costs that come with conventional mini-split installs.
- Strong comfort upside: buyer reviews mention solid heating and cooling performance once installed and running.
- Potential operating-cost improvement: some customer experience notes lower electric bills compared with older, less efficient equipment (results vary by climate, insulation, and what you’re replacing).
- Good fit for 115V situations: in a workshop or older home where adding a 230V circuit would mean panel work, staying 115V can be the cheapest path.
The Bad
- Connection tolerance can make or break the “DIY savings”: some homeowner reports flag connector/fit issues that stop the install at the finish line.
- If something arrives damaged or out of spec, returns and replacements can turn a “cheap kit” into a time sink.
- Electrical requirements still matter: you may still need a dedicated circuit and an outdoor disconnect — work that’s best handled by a licensed electrician (NEC-certified) to stay code-compliant.

“A great solution! I was able to DIY this project 100% (did have some help lifting the gear to mount to the walls). The install was involved in but manageable. Lines and power installed with ease. Outstanding heating and cooling capabilities. This was the best purchase I’ve made all year, a big quality of life upgrade that is already bringing down my…” — Verified Amazon buyer (5 stars)
“i followed instructions to the letter. When i got to literally the very last connection to be made to complete the installation the two mating connectors would not connect. I tried for over an hour to even swap ends of the line to the connector on the other end and no go. I have to uninstall everything I’ve done, box it back up and send it back to amazon. I…” — Verified Amazon buyer (1 stars)
Typical price: $1700 – $1800
Our Take: If your goal is best price after you include installation, this is the MrCool-style buy we’d start with — as long as you verify voltage/circuit needs up front and you’re comfortable troubleshooting a DIY install.
MRCOOL Easy Pro 12000 BTU 115V Mini Split Heat Pump
Best for: A small-zone 115V setup (like a sunroom or office addition) where you’re prioritizing a lower kit price and you want a simpler purchase decision, even if the evidence base is mostly short-term “it works” feedback.
The Good
- Lower upfront kit pricing versus many comparable single-zone mini-split packages in this size range.
- Strong aggregated customer experience signal: it’s listed at 4.5/5 across 41 Amazon reviews, which is a decent starting point for screening.
- 115V-friendly for homes where running a new 230V circuit would add cost (or where a sub-panel is already tight on capacity).
- Buyer feedback themes include installation and getting it running successfully (though details vary by installer skill level).
The Bad
- Fewer specific, verifiable performance details in the buyer feedback we have here — so it’s harder to judge “best price over time” (heating in cold snaps, noise, service calls) versus day-one cost.
- If you end up needing electrical work, line-set changes, or condensate accessories, the cheaper kit price can get erased quickly.
- As with any mini-split, incorrect sizing can negate savings — an HVAC contractor (NATE-certified) is worth considering if you’re unsure on load/BTU.

“It was very simple to install for a person that has some basic building, electrical, and hvac knowledge. Just follow the directions, it took me 2 days 2 people, first day was electrical setup, about a half a day. The second took all day at a deliberate pace, double checking everything, I had to work longer on a mounting solution that took in a longest…” — Verified Amazon buyer (5 stars)
“Complete piece of trash. Worked 1 time then never worked again. And their customer service is even more garbage then their product” — Verified Amazon buyer (1 stars)
Typical price: $1600 – $1700
Our Take: This can be a reasonable “best price” contender for a straightforward 115V single-zone job, but we’d be stricter about confirming exactly what’s in the box and planning the electrical/condensate details before you buy.
FAQ
What does “best price” really mean for a MrCool mini-split kit?
It means lowest total cost for a comparable, complete setup — not the lowest listing price. To compare fairly, normalize what’s included (indoor head, outdoor condenser, line set length, control options), then add likely extras like a pad/stand, line-hide, condensate drain routing, and electrical parts (disconnect, whip, breaker, wiring). The U.S. Department of Energy overview is a good primer on how ductless mini-splits fit into home heating and cooling and why installation details matter: U.S. Department of Energy ductless mini-split guidance.
What’s typically included in a MrCool “kit,” and what might I still need to buy?
Many kits are sold as a system package (indoor + outdoor) and may include items like a remote, mounting bracket, and a line set, but inclusions vary by listing. Common “still need” items include an outdoor disconnect, electrical whip/conduit, a mounting pad or wall stand, line-hide cover, and a condensate solution (gravity drain routing or a condensate pump if you can’t maintain slope). Before checkout, confirm the exact line-set length and whether any specialty adapters or communication cables are included.
Is 115V or 230V cheaper long term for a mini-split?
Long-term cost is mostly about efficiency and runtime, but the “price surprise” for many households is electrical work. If your space only has 115V readily available, choosing a 115V unit can avoid the cost of running a new 230V circuit, adding a breaker, and installing an outdoor disconnect — work that should follow NEC requirements and is often best done by a licensed electrician (NEC-certified). If you already have 230V capacity and need higher BTU (larger spaces), 230V options can make more sense.
How do I compare efficiency fairly when shopping by price?
Look for efficiency metrics like SEER2 (cooling) and HSPF2 (heating), and verify that the numbers apply to a matched indoor/outdoor combination. ENERGY STAR explains the newer SEER2/HSPF2 framework for modern comparisons: ENERGY STAR efficiency guidance. For apples-to-apples performance verification, you can also cross-check listed ratings in the AHRI Directory (matched systems are what matter, not just a brand family name).
How do I choose the right BTU size for my room or zone?
Square footage is only the start — insulation quality, ceiling height, sun exposure, and your climate zone can swing the load a lot. Oversizing can lead to short-cycling and poorer dehumidification, while undersizing can run constantly and still fall behind on the hottest/coldest days. If you’re not confident, getting an HVAC contractor (NATE-certified) to sanity-check sizing (or referencing ACCA Manual J principles) can prevent a “cheap” purchase from turning into an expensive comfort problem.
Do MrCool mini-splits heat well in freezing weather?
Some do, some don’t — and this is where “best price” can flip. Mini-splits can lose effective heating capacity as outdoor temps drop, so you’ll want to look for clear low-ambient heating performance information and matched-system ratings rather than assuming all heat pumps behave the same in a cold snap. If you rely on sub-freezing heating, paying more for proven low-temperature performance can be a better value than the cheapest kit.
Will I need permits or a disconnect for a mini-split?
Many jurisdictions require permits for HVAC and electrical work, and outdoor equipment commonly requires an accessible service disconnect. Requirements vary by location, but electrical safety and code compliance are the consistent themes — and it’s the kind of detail that can add cost if you didn’t budget for it. When in doubt, have a licensed electrician (NEC-certified) confirm circuit sizing, breaker requirements, and disconnect placement before you commit to a specific voltage/model.
Bottom Line
If you’re chasing the best price on a MrCool mini-split, start by sizing the zone correctly and confirming your available power (115V vs 230V), then compare only truly comparable kits. For most budget-minded homeowners who can realistically handle the install work in a small-zone setup, the MRCOOL 12000 BTU 115V DIY Mini Split Heat Pump System is our top pick because it’s designed around minimizing total installed cost — not just the listing price.
