We got regular 6 month service today and the service guy said our heat pump unit has no freon and the unit must be replaced. He said the unit had been running on no freon for a while (last service was 1/25/05-no problems) and because the freon also lubricates the system, it is probably un-fixable. He also said the unit is 10 years old (Trane manuf. in 1995) and units only last 12-15 years. He a gave me a price for trying to fix the unit that was 20% of the price of a new unit. Given the age, and the probability of a successful fix, he recommended we buy a new unit.
We bought the house 5 years ago and went with the contractor that the previous owner recommended (I assume they installed the unit as well, but I'm not sure). They are a large regional outfit that seems to have a good reputation.
Being a typical homeowner, I don't have a clue if we are being shammed, or the guy is speaking the truth.
Any guidance would be greatly appreciated.
