Above i wrote a neg review for Lassen Heating - there was a misunderstanding. Mr lassen worked with me directly for a long time. the issue is NOT with Lassen i see now. the issue i have is with Carrier brand Support. I bought the house 2 years ago and Mr Lassen installed the system and he was never called to service it for many years. today we talked and he assisted me and offered me some valuable advice. i appreciate his time and patience.
