Its a honeywell wireless thermostat.

Townsend, I change my indoor filter every month. The outdoor unit is on a platform about a foot and a half off the ground and is totally free of any blockage. Btw all of my vents are in the cieling including the returns with the exception of one vent and one return. The thermo is on the biggest room which is the living room and the temp seems to be higher in there then in my bedroom which is in the rear of the house. My living room kitchen and dining room is an open floor plan so if your cooking the temp in the room goes up turning the air on. I bumped the temp up a couple degrees and it seems to be running less.
