Steve, thank you for the additional information. The contractor does have an obligation to make sure the unit was installed properly. If it was not, then they need to correct it.They should be able to identify the problem and if they can not, need to bring in a 3rd party / outside source, to determine what is wrong. If they are unable or unwilling to do so and you have to do this yourself, you could have a basis to sue the contractor for damages. The difficult part is going to be able to go after them for damages, as a result of the system not heating and cooling for around $1000 a year, like they said. They could always make the argument that this was just an estimate and your use effects the true cost, which they did not know at the time. However, you can always argue that you relied on their representation
, which resulted in you buying the unit, which was false and misleading. You would also need to determine the relief which you seek, which could be the cost above the $1000 from the time this was installed until now and the replacement cost, for another unit and any refund, for the unit which you bought from them. It is going to be your word against theirs, since nothing is in writing and up to the Judge or Jury, to decide who to believe. It is possible, that the reason that the bill is so high, is a result of the improper installation, which is something which should be determined ahead of time, since it could be an easier fix, then having to sue.
