Wondering if you can install AC yourself?

Check out this video showing the basics of installing a Mr Cool ductless mini split air conditioner system.

Mini Split Frequently Asked Questions

Please reach us at info@ductlessacdirect.com if you cannot find an answer to your question.

Modern mini-split AC / Heat Pumps are the most efficient way to cool your house in the Summer and heat your house in the Winter.  You WILL save money on your utility bills, and you will be very comfortable.  Also, these systems are FAR less expensive than traditional ducted systems, and they are much quieter.


As much as 1/3 of all cooling or heating capacity is lost when air travels through ducts, and ducted systems can't easily be zoned, so you can't cool or heat only the rooms you want, you have to do the whole house.  This makes ducted heating MUCH LESS EFFICIENT than ductless heating.


  • We sell Mr Cool equipment, which has the best warranty in the business, and also uses patented quick connectors for AC coolant lines.  Not only are these connectors much easier to connect together (you just need 2 wrenches), they are also MORE RELIABLE than older type AC flare connections (which have to be done by a specialized AC technician).  
  • Older type AC flare connections (copper tubes which are widened, or flared at the ends to attach to the AC fittings) have a very high rate of failure.  If the flares are not done precisely the right way, or if there is vibration, the flared ends of the copper AC lines can crack or loosen, and the AC coolant will leak out.
  • YES! Mr Cool equipment really is DIY!  Because the AC systems and connection lines are all pre-charged with the right amount of coolant and use Mr Cool patented quick connectors, NO SPECIAL AC TRAINING OR EQUIPMENT IS NEEDED!  You will not be adding, removing or otherwise handling AC coolant, any more than if you were to put in a window AC unit.  
  • So if you are comfortable doing moderate DIY projects on your home, you can install a Mr Cool system.  The only licensed professional you may have to call in is an electrician, because of course all AC systems require power.
  • If you are not someone who does their own home improvements, Mr Cool systems are still a great choice, because they are extremely efficient, reliable and the installation will still cost less, since only an electrician and any competent general contractor or handyman can accomplish the installation.


Absolutely! One thing that sets us apart is that EVERY system we sell comes with a free phone, zoom or other online session to help answer all your installation questions.


We are also happy to answer your questions and help you pick the right system BEFORE you buy.  We love talking about AC!


Air conditioning systems cool a house by transferring the heat in the house to the outside.  Even though it may be very hot out, .the AC system removes heat from the interior of your home, sending it outside and cooling your home.


A heat pump is simply an AC system that is capable of running in reverse, and transferring heat into your home from the outside.  Even though it may be very cold out (Mr Cool systems can provide heat in temperatures as low as -13F), there is still always some heat in the exterior air.  A heat pump concentrates this heat and sends it inside.  Unlike furnaces or boilers that may burn gas or oil, heat pumps don't generate heat, they simply move it from the exterior to the interior.  This takes less power / energy than generating heat with gas, oil or by using electricity to warm up heating coils.


The answer to this question is "maybe", or "some of the time".


If you live in a moderate climate, where winter temperatures rarely get below freezing, you can likely heat your home exclusively with a heat pump. 


If you live in a very cold climate, your heat pump will still work, but when it gets very cold out, it may not provide enough heat.  This is because heat pumps typically give about as much heat capacity as cooling capacity for any given space.  For example, if you have a good sized family room, say about 600 square feet, and you live in the Northeast, you will need about 18,000 BTU of AC cooling capacity to cool the room on a hot day.  However, in the winter, the same size room could require almost double that amount, 36,000 BTU to heat the room.  You could use a larger system, but that wouldn't be cost effective for cooling in the Summer.  Instead, it is recommended that you retain a gas, oil or other heating system to help heat the home on very cold days.  If it is not very cold out, say 48 degrees, you won't need to use it!  This way, you will still save money, but when it gets to be deep winter, you will still have enough heat.


Yes, absolutely! You can keep your current system, but adding ductless mini-splits to one or several rooms can be highly beneficial!


For example, in the Summer, on a hot humid night, having ductless mini-split AC in bedrooms  can allow you to turn off or turn down your ducted AC system overnight, keeping you comfortable while you sleep, and DRASTICALLY REDUCING electricity usage.


The simple answer to this is that they are either mis-informed, unfamiliar with Mr Cool, or don't want to encourage people to buy equipment that does not require their services to install.  Mr Cool systems have a high reliability rate, equal to or better than any brand in the industry.
