No, unfortunately all of the mini split systems sold on our website are required to be installed by a licensed HVAC technician, otherwise the manufacturer's warranty is voided.
It is strongly suggested that you have a licensed HVAC technician physically inspect the area and offer a sizing recommendation. MS4L and its representatives will never recommend BTU sizing as we are not able to physically inspect your location, thus we cannot give you an accurate estimate.
There are a number of factors aside from square footage that determine how many BTUs are needed to cool/heat an area. A few examples would be window size, insulation, ceiling height, appliances, pets, and room occupancy.
