The central A/C and heat in my house aren't working properly and I need to figure out why. All the equipment (or whatever you want to call it) is about 24 years old.
The problem started about a month ago when the heat was on. I noticed that hardly any air was blowing out of the vents and the air that was blowing out was cool, not warm. Also, the lights in different rooms would dim every 4 minutes or so. I turned off the heat at this point and notified the owners of the house who happen to be my parents.
I turned on the A/C this morning and the same thing is happening. The lights in different rooms dim every 4 minutes or so and hardly any air is blowing out of the vents. The fan is set to "auto" but everything has been running nonstop since I turned it on over 4 hrs ago, which is not normal. I think it's running nonstop because the house temperature hasn't reached the temperature I set the thermostat to. At this rate, it never will because it's hardly blowing out any air.
My father says he put in a new filter, but this was after the problem started a month ago. He mentioned that the unit might need more Freon, but I think he checked that out because he came back saying he doesn't know what the problem is. He mentioned something about getting someone to check the pressure (whatever that means), but knowing him this could take weeks and I'm burning up.
Does anyone have an any idea as to what might be wrong? And since the lights keep dimming, will that harm any of my electronic equipment, like my computer?
