Mak sure cabin filters are good for a clean evapor cecil bearden 09/07/2012 @ 7:25am My TS1110 New Holland had a great A/C 2 years ago when I bought it. It began to blow less air every time I used it baling. I took off the roof and found that only 10% of the evaporator was open. The rest was clogged with a mixture of mold and dust that had turned into something like tar paper. I cleaned the evaporator and coils with a window cleaner and blew everything out as well as possible. Then checked my filters and found a hole in one of the outside filters. I installed new filters and the A/C would freeze me out in 100 deg temps. The compressor was cycling also. I found that I used nearly 20 gallons less fuel each day after cleaning the evaporator. That compressor takes a lot of horsepower when the evaporator is clogged. I figure I paid for those New Holland cabin filters in about 2 days.
