Since my system was installed last year I have not been happy with the filter situation. The system works great, but I feel airflow is lacking. Possibly these two issues are related. I will...

Yes, I am aware that opening the windows would be more efficient. :rolleyes: Sometimes, you just aren't there to do so...or you forget. I was wondering what temp damage would occur at.

I also had my decision down to Carrier units (24ACA4) or Tempstar units (T4A4). I decided to go with the Tempstar units, and I am very happy with the decision I made. During my research I found the...

High limit switch? Is this something that is tripped if there is too much static pressure? If so, why would the unit run fine in cool mode? Is it possible the installing company sold me a size too...

He is correct on both...The outdoor unit is a 13SEER A/C Condensor 4 TON. Probably new in '05 or '06.

Not sure why it would be marked as heat pump?

I am not an HVAC pro, but I am a pro on this exact question. I was quoted for two mainline Tempstars (Model T4A4) but the day of my install the HVAC company arrived with two of Tempstar N4A4.
