Would a 4 ton or 5 ton work in a greenhouse that is 1800 square feet for year round production?

Is this unit a down or up draft unit?

How many amps does the condenser draw...airhandler
For the air handler you will need a minimum circuit ampacity of 4 amps and a maximum overcurrent protection (A) of 15 amps. For the outdoor condenser, you will need a minimum circuit ampacity of 35 amps and a maximum fuse size of 45 amps. For more assistance, please give us a call at 1-888-377-2850. 
Where are they manufactured?
MRCOOL is based out of Kentucky however most of their mini-splits are manufactured in China.
Can you use the existing freon lines at a home?
The Mr. Cool Universal series uses pre-charged 'quick connect' line sets which are a specialized product that allow for connection without using a brazing torch to 'sweat' the refrigerant lines together. Other, similar brands are available without these quick connect fittings. The Quick Connect fittings can be removed, which would allow you to re-use traditional copper, but then you would need to use copper stubs and an acetylene torch to sweat the connections. If you have any further questions or need further assistance, please feel free to reach out to one of our experienced customer service representative and they would be happy to assist you. Thank you and have a wonderful day.
When r410a is eliminated will these systems be able to swap to the new refrigerant?
Great question. Today’s equipment is specifically engineered to use R410a refrigerant only. Due to every refrigerant having its own unique pressure/temperature relationship, it will not be possible to use another refrigerant in a piece of equipment except for what it is engineered to use. If you have any further questions or need further assistance, please feel free to reach out to one of our experienced customer service representative and they would be happy to assist you. Thank you and have a wonderful day.
Does this come with a thermostat? If not what one is recommended?
Thank you for your question. This system does not include a thermostat. It is compatible with most 3rd party thermostats. You can even upgrade to a smart thermostat if that is something that interests you. The only thing to make sure of is that when installing the thermostat that the wiring diagram if followed correctly. Some of our best selling thermostats for this system are the Cielo Breez and the Ecobee. For more assistance, please give us a call.
Can this system be zoned?
Thank you for your question. Yes, since this system utilizes the ductwork in the same way as a traditional system, it should be fully compatible with zoning and dampers.
