I apologize for sounding completely , but I'm desperate!
We bought our home yesterday and the unit is on and running - we set it to 75 or so last night and then came back to the other house. I went in around 6pm tonight and it was still about 90 in the house. The unit passed inspection fine and we have a home warranty, but the contractor won't be out til Monday. What can I try until then? We're in Fort Worth and it's HOT down here. We do have ceiling fans and I did find an exterior sliding door cracked about an inch when I arrived today - someone tried to shut it without pulling the safety pins back first, so it stayed open. My tall friend said that the air coming out felt cool, but I'm not understanding why the house feels so incredibly hot.
The thermostat itself is an original '77, and I don't know what kind of unit it is - we're not at the house tonight, thank goodness. I know the therm could be off as far as the temp it's showing, as it's incredibly old and probably unreliable. I'm just looking for some basic ideas that a helpless girl can try over the weekend. Being from rural MD, I have NO idea what to make of any of this extreme heat. The man we bought it from hadn't used the unit in about 3 or 4 years, but the inspector seemed to think it was just fine and completely operational. Help?
