I was on a service call this morning for a ductless split system. The complaint was "not enough cooling" first thing i did was take a discharge air temp reading of 35F..i was expecting to see 55F. so i cleaned out the one filter i could reach, the rest of the unit is behind a massive flat screen. i put in the cleaned filter and cheked my pressures, gauges read 55psi suction..the remote was set to 71F and the compressor would shut off well before temp is reached and my pressure would drop to 50...with the tv infront of the unit i wasnt able to look much further into the call and told them i will be back once the tv is moved...My question is would the tv be causing a return air flow issue and adding heat to the room temp causing the low supply temp? any help would be great Thanks..
