Critical: Quality
They put in ac. Now I’m going into the second year of no ac because of a pinhole leak somewhere and the system is only eight years old. Still under warranty but I was quoted over $800 to fix. I don’t think this is right. We had things done before retirement and now my husband has passed away and I don’t have the money to fix it.

Had them come out to diagnose my AC. They replaced a part for $300+ (didn't provide a receipt). Less than 2 days later, the same problem still exsited. They came back out again and provided an estimate of another $472 dollars (didn't itemize the parts, labor) just provided one lump sum figure (convenient for a contractor). As far as I can tell the parts cost $200.
If you call a contractor to come out, you would hope they would fix the problem the first time, and provide a quote that has itemized costs. Proceed with caution.

I totally agree with previous review. Technicians are friendly. The "receipt" I received for work done was illegible, a carbon copy of very poor handwriting and poor quality paper. Indeed the owner called the very next morning to see if I wished to proceed with a brand new unit (heating/cooling). All I wanted was to have a part replaced, which was quoted at very high price. Was "high pressure/sales" from tech, was told it would improve value of my condo for resale purposes to replace system. Was not in market for new unit, just repair.
