Single, Dual, or Total Zone Control

A single MrCool ductless mini-split heat pump unit is designed to provide effective and efficient air comfort to a single zone in your home. What is a single zone? Don’t worry too much, because it’s a pretty simple concept. A single zone in the average home is just a typical room. Your kitchen? One zone. Your garage? One zone. Your living room? One zone.

I think you’ve got it.

What happens if you have multiple zones (i.e. – multiple rooms) in your home that you want heated and cooled? The answer is multi-zone installation. How does that work?

All you have to do is install a single MrCool unit in every zone you require air comfort. Not only will you get reliable performance, but you’ll be able to customize the environment in every zone to your personal desires.

For example, a kitchen can get pretty warm compared to the rest of the house when your cooking and baking. With multi-zone control, you have no worries. You can increase the cooling in the kitchen without freezing everyone elsewhere in the house.

Want to keep the bathroom warm on those cold winter mornings? Multi-zone heating will take care of that. Tick the heat up on the MrCool that services the bathroom, and stop freezing when you hop out of the shower.

  1. I have a 12 unit Apartment Building that I think this will be a perfect solution for. One of my questions is the remote control. I would need to be able to get replacement remotes. I think an excellent solution would be wall mounted remotes (to reduce breakage and loosing them). I would like to talk with someone about this as a solution to my HVAC for these buildings.

    1. Replacement remotes is something we can help with. Give us a call at 270-366-0457, ask for Daniel, and help however we can.

  2. I have a small ranch one level house with 5 rooms split into 1100 sq ft total space and I was interested in a 2 zone cooling system – one in living room and 1 in the master bedroom situated mounted on the wall in an effort to cool the one level 5 room house. Would this work for the total sq ft I have (1100 sq ft) and what would I get an 18,000 or something a little larger? Also, where in Mass are your products sold? Any assistance is greatly appreciated. Thanks

    1. This is something you could potentially do! You may want to size up the mini split, though, to something like our 27k BTU or 24k BTU models. The size of the unit your home needs is also dependent on your insulation level. There are also options with the air handlers available, as well, and how much square footage they cover. That is to say, converting your home’s cooling system to mini splits is not impossible.

  3. I have a small cabin (864 sq ft) and looking for 3 zone unit. I see buying 3 separate units is much less expensive than buying a 36k BTU 3 zone unit. What is the preferred method? 1 unit or 3 units to so 3 rooms?

    1. That is really up to your personal preference. The main difference is that three individual units would need to be wired separately while a single three-zone would only need one disconnect and breaker.

    1. Sometimes. The way that could work is if you installed a multi-zone capable condenser with a single-zone initially, and then added other zones later. There are capacity requirements you would have to observe with the single air handler on a multi-zone condenser though.

      1. Could you please elaborate? I have a 3 zone unit but only wish to install two heads for now. What do I have to be aware of? Also, can I disconnect and reconnect the DIY connectors once or twice?

        1. The attached air handlers must equal at least half of the capacity of the condenser in order to operate correctly. For example, if you had a 36k BTU condenser and four 9k air handlers, you would have to install two 9k air handlers to meet half of the condenser’s capacity. It is not recommended to disconnect the pre-charged line set once attached.

  4. I have two rooms that I would like to install a multi zone unit. Can you heat one room and cool another with a multi zone condenser and two head units?

  5. Hello, I would like to install one of your units in a large garage ( 32′ x 40′ x 18′ ceiling ) would you recommend a single head unit or would it be better to use a multi-head unit ? Would it be easier for the unit to heat and cool more efficiently with multiple heads ?

    1. For that space with that high of a ceiling, you may want to consider getting two units. Normally, a 36k would be a sufficient fit for a 1,200 square foot space, but since the ceilings are so tall, you may want to think about getting two smaller units. Climate, sun exposure, insulation, the amount of people normally in the space, and other factors also affect unit sizing.
