1. I had the exact problem with my A/C a couple of weeks ago. My house is about 2 years old. Filters looked fine. It was a refrigerant leak at the outdoor unit. Low refrigerant pressure. The technician can come out and use a freon “sniffer” to find where the leak is coming from, then replace that component. It shouldn’t be too terribly expensive. Fortunately I was barely still under warranty.

2. I hope that it is nothing major or costly, but I have a question. Why not shut the A/C down and use fans and open windows exclusively, especially at night? Your energy savings would be enormous.

3. We often shut down the A/C and use the windows and ceiling fans. But that doesn’t help when it’s too hot for that. We live in the South which can get *very* hot and humid, so the A/C also makes our house liveable by reducing the humidity. Moreover, I’m willing to pay for comfort. Our bills aren’t actually that high.

4. If you can, take the cover off of the indoor portion of the A/C to take a look at the coil. If it has iced up at all, you’ll want to turn the system fan on to keep air moving through, to melt any ice and dry it out. That’s thing number one to do whenever an A/C system loses effectiveness, as the more time the coil spends iced, the larger problems become.

5. Humidity is coming. Get that A/C fixed right away!
