I'm interested in exploring options for a 40-inch stainless steel air conditioning unit. Could you please provide detailed information on the available models you have in this category? Specifically, I'd like to know about the features, energy efficiency ratings, and any additional specifications that might help in making a decision. Additionally, please include your pricing structure, including any bulk discounts if applicable. It would also be helpful to understand your lead times and warranty options. Looking forward to your prompt response so we can discuss this further!
