Not the review they want
June 17, 2026I was high pressured into getting my new units, by a very savvy young man. My old units were working fine, but was told by the salesman, who won’t return my calls since the sale, that the new units would be quieter and more economical. These units are MUCH louder than my previous units!!! I was told they would scan and clean my vents, but that never happened! They left me with no person to follow up with. There is no one to ask about service, or any follow up questions I have!
