"My in-laws AC went down so I called these guys and they came out and were great and said the motor was bad and set up a new one and replaced it. This unit supplied 2 areas or 2 zones. Well this "fix" worked a bit but was weird as it would blow sometimes etc so we called them back out. He said that he did not now it was a zone system and mis-wired it, but it is very visible that it was and he said he rewired it. So we hoped it would work and he checked it and said all is good and left. Well is worked for a day or so but once again was nothing like cooled before. So we called him back and he said the motor burned out again. He said it was water splashing on it. But there was no water as we were trying to use the heater as it was really cold. My in laws and us had to buy portable heaters to keep warm. So my in-laws called him back and said it stopped. He checked it out and said the motor burned out/stopped again. He said he has to get another motor but they are out and will have them in"

Heating and Air Conditioning questions, answered by experts

No, you don’t need a ductless unit in every room. Ductless AC units don't work the way that window units do, where the air doesn't travel outside that room. The indoor air handlers all attach to the outdoor condenser. While the air doesn't travel the way that traditional ductwork would, the ductless AC units create zones so that one part of the home can be cooler than another. They can spread effectively enough that indoor units only need to be placed in main living areas.

A few drips here and there should not be cause for concern, but if your unit is leaking a large amount of water, then it’s advised that you stop using it until the problem is identified and a solution is determined. The more you use it during a leak, the more issues it will cause.

DIY is possible for basic cleaning. Professional services handle advanced maintenance like recharging the refrigerant.

You can air condition your Arizona room by extending your home’s existing HVAC system or adding a ductless mini-split system. Arizona rooms that have full windows rather than screens only are a better choice for air conditioning—screens will let the cold air out as fast as the air conditioner can make it. 

You may never need an AC recharge if there are no leaks. However, if your AC unit has a leak that cannot be patched appropriately, you’ll need an AC recharge every time the freon level drops low enough that it disrupts your system—this could be once every two to three years. It all depends on the size and frequency of the leak.
