Take those bushes add about 10' to them and let them hang over the top of the Lennox. My 2nd no-cool this AM. I couldn't believe it when she said "it's in there" and all I could see was bushes. Sad part was, one of my co-workers was there recently to reset the high pressure switch and didn't tell them to trim back the bushes.
Went on an old XV1500. customer was complaining to dealer because they'd lost 3 compressors in 9 years. We had to use a machete to get to the unit. I didn't have much sympathy on extending the warranty.
We had to change out a compressor in an ancient TRANE condensing unit once. It was a 20 ton unit for a restaurant and it had trees growing around it. And through it! We got the sawsall and some rough-in blades and made us some working room. The restaurant manager wasn't happy at all but, our reasoning was the trees got cut or the ac stayed broke, your choice. They made their decision and we fixed the unit.
