During estimation process I wanted an old humidifier on another section of duct removed. When they installed the new one on the main unit, was told "We'll take care of it". Agreed to proceed, on the day of the job I again confirmed that the old one would be removed, was told "We'll take care of it". After the new humidifier was installed (which was done well) the old one was still there. I called and was told this was not part of the job and "We'll take care of it" means that they'll give me a separate estimate for that work, which turned out to be $250! Spoke to the manager, got nowhere. Very deceptive, felt cheated. Beware.
