What Causes an AC to Freeze Up?

Monday, July 17th, 2017

At first thought, a freezing air conditioner may not sound like that big of a problem. After all, you want your AC to be cooling your home, right?

Monday, July 3rd, 2017

woman-with-fanUsually when we talk about leaks in air conditioning systems, we may be talking about oil or, unfortunately for some, refrigerant. However, every now and then we get a call from a homeowner concerned that their air conditioner is actually leaking water. This is not only alar ng, but also perplexing. After all, it is not as though an air conditioner actually uses water in its operation, right?

Well, that doesn’t mean that you are seeing things if you notice water surrounding your indoor unit, nor does it mean that the water is leaking from elsewhere in the house and is just pooling here. The air conditioner may well be the source of this water.
