Our home isn't 7 years old yet and we've had constant AC problems. Last summer, late in the season, the main level AC failed so we added freon to keep it going for the last hot month. We are told the coil is shot and needs replacing. I am shocked that this has occurred in such a new home! We can not afford to have it fixed right now, for the quoted price of $1,600.00, with hubby having been unemployed since Nov. 2010. Like others have also reported, the smaller unit for upstairs does not cool below 80 degrees in the temps we have right now. Of course the Master BR is over the garage so we expect to be warmer but is it better to keep the doors closed in the Master to contain cool air or leave them open? Any recommendations for less expensive repair are welcome too! Its almost 90 degrees in most of our home right now and its difficult to make meals in the hot kitchen, even with 3 fans running. Does anyone know what the warranty is supposed to be on these units? I'm REALLY hoping its 10 years so we can get this fixed!!! I appreciate any help provided! THANKS!!
