## What is MRCOOL SmartHVAC?

MRCOOL SmartHVAC App works with MRCOOL Smart Controllers to convert MRCOOL Air Conditioners & Heat Pumps to smart ones. Our smart controllers work with this App to help you convert your existing or new ACs to smart ACs. You can control your MRCOOL ACs through your smartphone or simple voice commands (our smart controllers are Alexa & Google Home enabled).

These DIY controllers are extremely easy to setup. You can automatically turn the air conditioner or heat pump OFF when you leave the premises and start to cool/heat once you arrive as per your settings. This App gives you complete control of your heating and cooling. It figures out when you're at home and when you're out and adjusts the settings to provide comfort and energy savings.

You can set weekly schedules for your air conditioners, monitor usage history, set air conditioning action in relation to your locations, see the air filter status of your AC and lot more. You can set intelligent temperature based triggers for your air conditioners by using the ‘Comfy’ feature under ‘My Rules’ section of the app. Comfy lets you set triggers to personalize the operation of your AC. It helps you automatically change your AC settings if room temperature goes above or falls below a pre-set value. It helps you reduce your energy bills with lot of convenience.

Continued use of GPS running in the background can dramatically decrease battery life.

### 4/5 — Works well, but needs polishing

*2026-08-01, version 4.3.0*

Overall the app works pretty well once the wifi adapters are added to the units. There are a few minor inconveniences that I hope will be fixed in future versions. For instance, there are a couple functions on my Mr. Cool remote controls that aren’t available in the app (turbo mode, LED off, etc.) that should be included. The ability to set schedules and link units is a big plus.

### 1/5 — Terrible app honestly

*2026-07-21, version 4.3.0*

This is probably the worst app that I have on my phone. 
Pros: really easy to connect mini-splits without the need to connect to unit’s WiFi (finally!).
Cons: 
• App doesn’t care to check if unit is turned on or off by remote! 
So if you turned it on in the app and then turned off with remote - unit would be displayed as “forever on” in the app, or if you turn it on with remote it would say Off all the time, and never even care to send a simple call to unit’s api. Beyond ridiculous.
• With remote you can first select the mode and then turn on the unit (which is how it should be). In the app you HAVE to turn it on first and only then it would allow you to change it. Ridiculous.
• I have five zones. Four units I was able to easily switch to Celsius. But not the fifth unit. For that last unit the setting is just missing in the app. I can switch it with remote, but if I use the app - it will switch it back. Looks like someone just forgot to click a button in the configuration.
• Overall lack of decimal degree setting everywhere. 
A common practice is to have x.5 C degree adjustments, but not here of course. Only full degree changes which is kinda ok with Fahrenheit, but way too coarse for Celsius. 
And what’s funny is that both the remote and unit displays have that decimal section, but it’s just not used because of some weird laziness I guess.
One degree Fahrenheit is roughly half a Celsius degree, so nothing stops it to be there.
• App randomly shows temperatures of the units at 2,5 times lower than it actually is. It’s random, but always around 2,5 times.
• Usage statistics is not only useless, but also very inaccurate. It can easily tell you that you didn’t use at all ac, when it actually worked all day.
• No energy consumption monitoring at all. Seriously?
My wonderful lg window ac not only shows me how much it consumes at the moment, but also day/week/month statistics, and even how much it cost me to run it.
• And lastly: you can’t reset your password! Emails never arrive. How, just how can you not care so much?!


Overall the application looks like it was made by someone who never actually tried to use it and didn’t care about it. 
An “Outsource” feel as much as it can be.

Being a software engineer myself I just can’t comprehend how someone cannot care so much about what they make.

### 5/5 — Mr Cool

*2026-07-14, version 4.3.0*

I love this mini split. It works so good in the summer and winter

### 1/5 — Worst APP

*2026-07-13, version 4.3.0*

3 full days to finally install the app with countless workarounds to finally get it to work. Using this to control a remote home in the winter to keep pipes from freezing and now I learned that in the event of a power failure someone has to be in the house to reset it. None of my other devices require this.

### 5/5 — Great for Cabin

*2026-07-11, version 4.3.0*

I have 2 zone unit at my cabin. After getting Starlink, I was able to install the smartlinks in both head units. Now I can monitor the temperature and turn on the AC or heat a few hours before I come up so it’s more comfortable when I arrive. Amazing!

### 1/5 — Error Eal OC

*2026-06-13, version 4.3.0*

Keep this error

### 5/5 — scott called me from mr cool great customer service

*2026-06-11, version 4.3.0*

i had issue i left a review they called me and helped fix it next day thanks Scott!

### 1/5 — Difficult to use

*2026-06-03, version 4.3.0*

Very trying to set up. It worked locally, then not remotely, asking to add devices when launching app which I’m pretty sure can’t be done remotely. Took dozens of tries to get working, forcing me to pry open Mr. Cool air handler door with a crowbar and reseating wifi thingy, which ruined my uwife’s phone ability to connect. Most frustrating was the offline error telling me my phone was not connected to the internet (it was). It’s working for now, we’ll see for how long. Well, it’s now disconnected (again). Apparently it doesn’t play nice with my eero switching from 2.4 GHz to 5 GHZ and disconnects.

### 1/5 — loses connection often

*2026-05-23, version 4.3.0*

for some reason randomly disconnects mini splits

### 5/5 — Easy Installing

*2026-05-17, version 4.3.0*

I gotta say I was extremely nervous on making this a project, but it was so simple so easy to I stal and operate. I highly recommend Mr. Cool!
