I have been in my new house for about 7 weeks & slowly I am finding the air from the central air unit is getting 'less cool'. I have a home warranty that cover the unit, is it worth calling up a repairman to have a look? Or is this something that I can remedy.
I would defintely call the contractor. Our new hame had a 1 year warranty. I would guess yours does also. The first year we lived there I called about every problem. Not that I had that many but the ones I did I could have never fixed anyway.
