2 years ago, I hired Jerry to install a new heat pump. I paid him over $7,000. Now, the unit is producing no heat. I found out that a true pressure line had rubbed up against the main freon line and caused a hole in it which caused all of the freon to escape from the unit. I contacted the heat pump manufacturer, Goodman, and they said it was Jerry's problem because it was a labor issue and not a materail issue. I contacted Jerry and he said that he only had a 1 year warranty on labor, since it has been 2 years, he could not help me. I got 2 quotes for over $2,400 to fix it. I still don't have any heat. I would highly recommend that you find someone to install you new unit who has more than a 1 year warranty on labor. Most HVAC contractors have a 5 to 10 year warranty on labor. read more
