Temperature in house not changing
The temperature in my house stays at 80 degrees. I have the ac unit on. The outside unit is running. I hear the thermostat click on, but I'm not sure I hear the large ton unit inside the house come on. I'm not really sure what this unit does. I do feel air coming out of the vents and it is cold. I have changed the filter, flipped the breakers, and made sure the outside units fan is spinning. The small pipe near the bottom of the outside unit is cold. I'm not sure what else to check and I'm not sure what the problem could be. I have called a tech, but I'm female and single and I don't want them to take advantage. I'd like to be informed.
