4 to 5 Ton 18 SEER Variable Speed MrCool Universal Central Heat Pump Split System - Upflow/Horizontal with Quick Connect Lineset - 35 Feet

My third MRCool.I had installed two MrCool DIY minisplit systems, both with excellent results. I trust this precharged technology more than a professional solder, vacuum, and charge system. In fact one of those minisplits was to replace a pioneer minsplit, professionally installed, that leaked.I figured, as with the DIY minisplit, the hardest part was done for me. The most difficult part left I expected would be the plenum/ductwork hookup. But I recognized that constructing a plenum would require basic skills. I was right.I was totally surprised by the quality construction of this MrCool, compared to the Lennox this 5 ton system replaced. It is a work of real craftsmanship. It is significantly heavier than the old one, both the air handler and the condensing unit, so get some help.MrCool support was very responsive in answering some questions on three occasions. They were great. I see complaints about this and windered because my previous experience with the minisplits and support was fantastic as well.I am totally sold on this concept. Be aware that the majority of HVAC technicians see this as a threat since their industry is highly protective. There are a very few who are willing to work with you if you must have help. I think MrCool can even help with that if necessary. I saved myself over $5000 for sure. And got a rockin' system to boot. For $10k I'd have gotten crap.I hooked this thing up and it ran like a tank. Works well, better than any system I've had in thirty years in this house. The condensing unit is very, very quiet compared to the Lennox. The air handler blows much stronger that the previous. It cools off quick and efficiently.Thank you, MrCool!

I only take time to review if I really think a product is exceptional or I hate it. This product delivers everything the literature promised at a great price. The instructions were very good and everything worked without even a support call. Couple of things to be aware of, first it’s big and heavy. I have a tractor and was able to use it to move the compressor to a pedestal behind my garage and lift the air handler to a shelf in my garage. I have a ducted system from my old gas packaged unit on the roof so I had to do all the ducting. That was the hardest part of the whole job. Secondly you also need to purchase a thermostat, I choose the Sensi smart and I’m totally happy with how well they work together. It’s been almost 110 here for the last week and it keeps cool and you can’t even here the compressor or the air handler inside the house. The MrCool hardware is definitely high quality and I’m sure it’s going to perform well for a long time.

I did the entire project single handed (except moving the 400lb compressor into place). Installation took about 20hrs, and another 5 hours was spent with the Mr. Cool tech support team troubleshooting my wiring and thermostat. After finally determining I needed to replace the thermostat, everything worked great!Instructions say to use a 3.5" hole saw, but I'd recommend a 4" since the linesets are pretty fat.Air Handler: need 30 amp double pole breakerCompressor: 50 amp double pole breakerThermostat wire: Suggest getting an 8-wire line, but you could probably get away with 5-wire.With the additional ductwork I needed, plus electrical components and a new thermostat, the entire project was about $6k - compare that to the $18k quotes I was getting from HVAC installers, this was certainly worth the time and effort. The tech support team was really great and they helped make this a 100% DIY project. Highly recommended.

This order arrived on schedule as promised. The price was better than several other suppliers. Shipping was totally free. The hydraulic tailgate and unloading service normally at an extra fee was included as promised as well. I installed the system along with all new wiring, condenser water drainage system and balanced forced air ducting system. It has been operating for just over two weeks and my daily electrical consumption, based on my Enphase Manager Solar system software, has been cut in half in comparison to the previous HVAC system. It is as quiet as promised and at our low temperature last week of 28 degrees Fahrenheit the forced air temperature exiting the registers was 105 to 109 degrees, no auxiliary electric heat coils were installed. My 2000 square foot home heated very quickly maintaining consistent temperatures as programmed on my Heagstat H725 5-1-1-Day Programmable Heat Pump 2 Heat/1 Cool digital thermostat I bought on Amazon three years ago.

Installed September of 2023. Evaporator coil sprung a leak around January-Feb of 2025. Mr Cool customer service is ok, but under their warranty they only send refurbished parts. The first coil was damaged in shipment due to terrible packaging, so I refused it. The second coil arrived with no packaging around it.
