I have a LENNOX HP21-45-230-03 three speed zoned system. The air compressor is bad. I am having problems finding a new compressor.
The high speed will not come on and at times, the entire unit won't come on. Please e-mail me if anyone knows whwere I can get one, new or used.
Thanks,
Kathleen Pilz

Air compressor? This is an AC unit with a Freon compressor. Inside speed is your air handler which is different,it runs air circulation in the house. We need a better explanation as to exactly what is not working properly, inside or outside?
