Need a reference for a reliable, reasonable, HVAC person. Air conditioner just went kaput! We have a Trane 1200xl. It has been working real good up until a few hours ago! The compressor tries to kick in, it made a noise, but no cold air! Husband has check the fuse box, pulled the main breaker, we turned off the unit then after about 20 mins turned it back on. Still, no cold air! Hubby is real handy all he needs is someone to tell him what to do!
