If I don't heat or cool down my dog house with an air conditioning unit, is it dangerous for my dog?

You can buy portable units for dog houses, which is really sensible as that way you can keep using it even if you switch to a new dog house. Here's a link to a site that specializes in air conditioning units to keep your dog cool and healthy. http://www.climaterightair.com/outdoor-pet-house-heating-and-air-conditioning

Short of gas. Time to call a technician

Unfortunately, I don't think you're going to be able to find a setting to best cool your house. The model that you have, is a room air conditioner that only generates 10,000 BTU's and is only rated for up to 400 square feet. That's about half the square footage of your house. It simply will not cool your entire house.

To make the most of what you have, place the unit in a room where you spend the most time. Close the door to that room and only air condition it. To keep the other areas a little more comfortable, close the drapes or blinds during the hottest periods of the day. If you have a ceiling fan in that area of the house, run it a fast as you can comfortably stand, in a clockwise rotation. Generating a wind chill in the area that's not air conditioned will help make it more tolerable.

I hope I was of help to you. Thanks for choosing fixture.

Hello, sounds like it is either a low charge or lack of airflow, what type of filter are you using? sometimes those filters that claim to be super effecient will actually cut down on your airflow and cause the ac to freeze up.
