      Q:Quick question: does the 26 amps power the outside unit and the 3 inside units? Or does the 26 amps just power the outside unit and we need additional amperage to power the 3 inside units?
      by|May 1, 2024
      1 Answer
      Answer This Question

      A:  The 26 amps will power the entire system. You will not need any additional breakers for the system. However, the maximum amperage is a 40 amp breaker.

        Q:How far will an air handler blow the air? Basically, if you are trying to cool and heat 2 rooms next to each other and the air can blow into both can that work?
        by|Dec 23, 2023
        1 Answer
        Answer This Question

        A:  It is possible. Placement of the air handler will play a big role in this. We do not have an exact distance of the air flow the air handlers reach.

          I tried for two months to get the unit and never could get all of the parts. They ordered it 2 times and never did get all of it. I told them to forget it.

          This is a AC system that most any handy person with some tools can handle with a little to no help. Don’t be fooled by buying one of the other brands like I did just to save costs. The Mr. Cool is well worth the extra cost since the materials and quality is so much better than the others.

          Worst purchase I have ever made.
          Purchased 2 36,000 units and they have both failed and failed again. The first unit failed in less then a year. Every time one of these pieces of junk fails I have to pay $400 in shipping for the replacement. shipping and the cost of a tech to recharge the units I’m into these pieces of trash for over $1000. I’ve only had them for two years. Mr cool customer service is a joke and you can look them up on the BBB website for proof. Thanks for nothing Home Depot you have lost a customer over this.
