Reviews for MRCOOL Universal 5 Ton 17 SEER Central Ducted Heat Pump Split System - R410A Inverter - Multi-Positional-R410A

The Mrcool heat pump and line set are working flawlessly. I did the whole install myself at 67 and it was fun. My furnace was in the attic of my two story house with no 220volts and zone thermostat controls, so the install had some challenges. The equipment arrived super fast with good communication. Very impressive packaging bolted to a custom pallet, wrapped with 1"+ cardboard and shrink wrapped. Arrived without a scratch and was placed in my garage. Thanks again for a great price, fast delivery, and impressive packaging!

I have been in the HVAC trade for 40 years and worked with just about everything from large chillers to -80 freezers over the years. I was very impressed with the Mr Cool system and will continue to recommend this product to others.

I LOVE this unit. It puts out more volume than my old carrier unit. This Mr. Cool unit is great, it was an easy installation but did take 2 and a half days which was longer than I expected, but I am a bit picky about about things being perfect. And I also built a new plenum to fit it better. You should highlight these units on your sight. I do recommend it to everyone with A/C problems that I meet and I also always highly recommend HVAC Direct. Your response to my shipping issues was impeccable and extremely appreciated.

Thanks for following up. I just had the system installed over the weekend. Everything is working properly so far. The shipping was very fast. Your website indicated shipping was 2-3 weeks, but it was shipped the next business day from ordering. I was impressed by that.

The only issue I ran into is the inaccuracy of the installation manual. The control signal wiring diagram in the air handler manual shows the connection of the D (Defrost) signal connecting to the D signal of the condenser. However, there is no D signal on the condenser. I just did not wire up the D signal for now. I emailed Mrcool support on Saturday, and is awaiting for the reply.

I just installed my first AC system and selected the Mr. Cool for a variety of reasons, but chief among them was that you can get pre-charged lines and do it yourself without any special equipment.

The product shipped on time and showed up in good shape. We dropped the condenser on a small concrete pad and installed the air handler in the basement. Then we learned about duct board ( if you haven't used it - buy the tools, use it, love it ) and installed the lines.

After doing a bit of electric wiring the system came online and worked right away. Excellent value for the price.

The only thing I'd change:

1. The instructions are a bit unclear on the low voltage wiring pin-out. The yellow wire needs to be connected DIRECTLY from the thermostat to the condenser. The wiring diagram makes it seem otherwise.

2. Modern thermostats switch between B and O ( AC and heat ) in software. Make sure the bit is flipped in your Nest or you'll be confused when the AC blows hot.

3. You need to build your own filter housing. This is stupid, but is the way it is.

All in all, a nice unit. Easy to install yourself and a great value for the money. Would buy again.

I needed to replace my central air and after having a mrcool mini split in m to garage for almost two years and having been impressed with it I figured I would get this for my house. Installation was pretty easy other than the weight, the only issue I had was hooking up the thermostat. Once the thermostat was hooked up everything has worked great for the last two months.
