Summer Cooling Tips & Tricks

Summer heat is great on the beach. It’s not so great at home, at the office, or when you’re mowing the backyard. Rely on MrCool’s patented (not really) summer cooling tips and tricks to beat the summer heat without breaking your bank account.

Summer Cooling Tips & Tricks

The simplest and most effective way to beat summer heat is with a MrCool air conditioner like the DIY, Advantage or Olympus I mean, obviously. If you are looking for non-mechanical ways to stay cool, we do have some suggestions.

Close the Blinds

Natural illumination is nice. It can also make your rooms a lot hotter in summer. If you want to keep cool without the a/c, close your curtains and draw the blinds. Believe it or not, blocking hot summer sunlight will help you stay comfortable.

Appreciate Your Fans

We appreciate our fans and you should too. No, we’re not talking about that weird guy at the library who always asks for your autograph. That guy is just crazy, and insanity does not reduce temperatures. We’re talking about ceiling fans and box fans. They won’t actually lower the temperature, but the air flow will make your feel a lot more comfortable. Fans, of course, use electricity, but not at the same rate as most conventional HVAC systems.

Stay Hydrated

Your body is quite efficient at cooling itself. Yeah, sweating isn’t exactly as comfortable as cool, crisp conditioned air from a MrCool Advantage, but sweat does work. The key is to stay hydrated. Not only will that help you stay cool, but it’s simply a matter of health and safety. If you get too hot and you’re not properly hydrated, you are at risk of overheating. That’s bad. Keep a glass of water handy.

  1. Under 12K DIY unit 110 volts or 120 does the dehumidifier use less electricity than the air conditioning?
    Thank you. Frank

    1. There should be a energy consumption decrease in dehumidification mode due to the controlled fan speed, but I doubt it is significant.

    1. An F2 error code indicates a problem with the temperature sensor. It might have been wired incorrectly or the sensor could have failed. I recommend you call our tech support team at 270-366-0457.

  2. Condenser and 3 9k btu indoor units.
    Indoor unit model #O-MULTI09HP-WMAH-230
    E3 error code, the fan won’t cycle in auto or while using the remote. I checked the connector is firmly attached at the circuit board.
    — error code, what does “mode conflict” indicate?

  3. 18000 unit 240 volt with heat pump. Got it set up in a building I use for complete storage sealer up what is my most efficient operation mode? Looking to keep building dry not so much caring about temperature but not wanting it 90 degrees obviously my options dry mode or auto or cool? Midwest humidity what will save me $ there is no economy mode from what I see. Thank you

    1. If you want to maximize dehumidification, you can operate the unit in Dry mode. It will still cool in Dry mode, but at a lower pace than in Cool mode.

  4. Is there a way to set the unit so that it stops blowing air when the desired temperature is reached?

    I have model DIY-12HP-WMAH-115AE

    1. Hello, thank you for reaching out.

      No, the fan in the indoor unit will continue to spin while the unit is on. The unit operates this way for a few different reasons:
      1) It’s more energy efficient. It actually takes less power to keep the motor going than it does to start it.
      2) Less wear and tear. The life of the motor is extended by minimizing the amount of times the motor has to start and stop.
      3) Humidity control. Continually spinning the fan means continually pulling humidity out of the air.

  5. When I use Dry Mode at 65 degrees, my humidity level goes up. What temperature setting do you recommend for dry mode? Model is a-18-hp-wmah-230a.

    I’d like to get additional dehumidification from this unit, any additional tips would be appreciated. Thanks.

    1. Your humidity level shouldn’t go up while operating in Dry Mode. You may need to give us a call on that. 270-366-0457

  6. My 1 year old Olympus started having ice build up inside unit. I switched to dry mode and the ice is gone and it’s keeping the house cool enough. Why is ice building up in cool mode? It happens by the second day of using it. I called your technical department 2 days ago and haven’t received a call back yet. Thank you.

  7. When in dry mode the temp drops all the way to 50 degrees no matter what the temp is set to. Is this normal?

    1. Are you saying that the displayed temperature shows 50 degrees or that the room literally drops down to 50 degrees?

      1. Hi I have a similar question; I have a 24K btu, 240V unit. In dry mode with temp set at 80 degrees F on front panel, it does a fine job getting humidity down into the 40’s (in Texas) but the actual room temp drops into the upper 60’s. Setting the thermostat doesn’t seem to control the actual room temperature. I love that the humidity is lowered, however I’m curious if I’m running up the electric bill keeping the room in the 60’s. The unit is in my 3-car garage shop which is fairly well insulated. It’s humid and in the mid-90’s in North Texas.

        When I run in cool mode, set the thermostat at 80, the humidity goes up into the 70’s.

        I would like to run the unit in Dry mode due to the low humidity in the room, however I’m concerned that in doing so will consume a lot of electricity.
        Thanks, LB

        1. The humidity is up in the 70’s when the thermostat is set at 80, since the unit wouldn’t have to run very long to keep the interior temperature at 80. If you set it at somewhere in mid-70’s, it should regulate the humidity more effectively since it will need to run longer.

          1. I have the same problem and I don’t think the MR COOL answer helps me.

            I have the “DRY” mode on, with the machine temperature set to 76.

            After a while, I can tell the dehumidifier works well, but the room temperature is way below 76 (despite the machine/remote still being on 76).

            Is there a way around this?

            How can we have the DRY mode ON without the room going to freezing temps?

  8. When in Dry Mode my 24k DIY 3rd gen will go to a much lower temp than the temp I set Is this normal?

    1. It could possibly be doing that because the drying mode switches between cooling and fan-only modes to maximize dehumidifying, but you can also give us a call at 270-366-0457 so we can get you in contact with tech support.

  9. I have the 12,000 BTu unit. Is there anything I should do regarding MAINTENANCE. I clean the filters at least every 3 months. What else should I do.

    1. Keeping the filters is the biggest thing you can do. You can also run the self cleaning cycle every few months. Once a year it’s a good idea to have the air handler serviced to have the coil thoroughly cleaned.

  10. In the history section on my smart app it shows red timelines where the unit is running I guess…0-24 hrs …all my bars are red daily at 72 degrees temp is this normal

  11. I installed a diy 36k mini split in my shop last fall and it worked great up to about two weeks ago when we again reached 90-98 degrees here in Texas. Today its 90 degrees outside with 15% humidity and in my shop it is 75 degrees with 83 % humidity.

    Im sweating more on the AC than outside??


  12. I have the 24000BTU unit. Every few weeks here in Texas, it starts a pretty steady drip out the front of the inside unit. I have cleaned the filters and drain line to the outside. What is going on?

    1. It may be that the operation of the unit is reduced or much quieter during this time, as the air conditioner will automatically clean and dry the evaporator with low fan airflow. If nothing at all is happening, please give us a call at 270-366-0457 as soon as you can.

  13. How do you run the Self Cleaning Mode in the FIY 3rd Gen? I hit the Self Clean button the remote but I don’t hear a sound or see anything change on the LED display on the unit.
