4 to 5 Ton 18 SEER Variable Speed MrCool Universal Central Heat Pump Split System - Upflow/Horizontal with Quick Connect Lineset - 25 Feet

I used this to replace a central gas furnace located under the house standing vertical. Heater was sitting on a concrete pad controlled by Nest Thermostat. House built 1979, flat roof, elevated floor, perimeter foundation, on mild slope, climate zone 7. Upon arrival all was well packaged on pallet wrapped and boxed. Quality of equipment (unprofessional opinion) seemed exceptional. Everything was well wrapped, all wires were well managed. Brass fittings, insulation on linesets seemed very high quality.Prework, do your homework well before ordering. There are a lot of factors you should consider before ordering or considering DIY. Do you have enough electrical capacity, can you wire 2 disconnects one for the air handler and one for heat pump (I didn’t have any disconnects). If your current equipment is being removed does the new equipment fit in the same space and if operates differently do you have the space to change configuration. How long of a line set do you require, do you require a new thermostat wire (7 wire is required) and is your current thermostat compatible.Install air handler: I needed to remove the gas heater, remove the gas line, remove old pad, create space and pour new pad. Luckily I had assistance from a licensed electrician during this install or I would not have considered DIY. Pulled new 8/2 to disconnect exterior where heat pump is located. 12/3 for air handler disconnect. Since air handler is bottom intake for return (previous was side intake) I needed to make a box for the intake which the air handler would be mounted to. Since this makes the air handler much taller needed to make significant changes to air collector plenum. Requiring cutting old plenum and resealing it since it was previously poorly sealed. My signal wire for the thermostat was 5 wire so I needed to pull a new 7 wire.Heatpump: Due to the land and underground water main I decided to mount to the side of my house. I ordered a mount that would support a lot more than weight spec. However when it arrived it was grossly under built. Made a new mount using Unistrut which can consume a considerable amount of time. Run line set: to plan I used solid copper wire to plan route and bends beforehand and if I have any extra length where it would be kept. Run your control wire to air handler and connect to your disconnect.Plenum required significant work including air sealing, insulation and trimming. I am not sure if I would consider this a DIY as it would likely be beyond a lot of people that would consider themselves “handy”. All in all I am very happy with the delivery, quality and result along with a significant savings of a DIY project.

Still have some clean up work to do (pipe hangers, yard clean up around condenser unit, etc.) but wanted to get this up for people that need to make decisions about HVAC units.Very pleased with how this unit is operating. It serves a large 3000 SF home with three floors including a finished basement. I set the condensing unit to the 4 ton setting and the fan coil unit to high fan speed. The house previously would have as much as a 5 degree temperature difference from basement to second level. That temperature spread is now 1 degree.With these settings the unit seems to easily keep the house at setpoint. Today is approaching 90 degrees and I have the Nest thermostat temperature set at 70 degrees. The unit has cycled on for about 30 minutes then off a couple times today. Surprising how quickly it is able to bring the temperature down inside. The old unit would run continuously on 85+ degree days.I really appreciated the "No Vac" fittings as I do not have a vacuum pump or a torch to braze fittings. It was really close, but I was able to make the 25' line set work. If I had it to do over again, I would order the 35' line set to keep the lines away from the front of the A-Coil. It worked out alright, I am still able to open and remove the front panel for access as needed.The unit is very quiet both inside and outside. I could actually hear my neighbors distant HVAC unit over the MRCOOL unit when I tried to hear how loud the MRCool would be.So far very pleased with this unit. My father in-law and sister are already asking if I would look into replacing their old inefficient units after seeing how great this unit looks and how smooth and quiet it operates.Ingrams Water & Air LLC shipped quick and easy transaction. Delivered as promised.Thank you!

I am out $5K over a furnace I can't use. Jacks claim a 30 day refund/replace policy but don't believe it. I mistakenly purchased this without doing enough research and from false info on this Amazon page. I admit that was mostlymy fault. I sent a return request twice and was told they would send they're respond within 48 hours. I have received absolutely nothing from them. I was willing to pay shipping and a reasonable restocking fee because it was mostly my fault but instead have 500 lbs of useless junk taking up space in my garage, $5K in credit card debt and a house being heated by kerosine heaters with the need of someone required to be home at all times.In defence of MrCool, it looks to be well built seems to be a decent product.

So far, so good. Install was relatively straight Fourways l forward once we determined the new L1 and L2 lines. The wiring diagram was not updated in the book but the internet had the answers. This thing really blows hard! Thinking to drop it to the 4 ton setting but overall, very happy with the purchase, install and huge cost savings of a conventional HVAC install.

Bought system from Amazon used Amazon credit card for reward points. Great well built system have been running for a month can already see big savings on electric bill.The unit is not energy star rated so I was not able to get rebate from electric company. Outside unit is quite
