Questions and Answers

Customer Questions
Would a 5 ton work in a 1800 square foot greenhouse and maintain a 70 degree temperature year-round in ND?
The Quick Sizing Calculator located at the bottom of our Sizing Guide will give you the quick answer of whether it's the appropriate size for your greenhouse or not. Regarding it maintaining a 70 degree temperature in North Dakota, I would recommend giving us a call and speaking with one of our experts about it. There are a lot of factors to take into consideration when setting up a system like this for greenhouse use. Our experts will go through every detail with you to ensure you're getting the appropriate system.
how big of a system do I need to heat and cool 3,400 sq.ft house ?
Please reference our Sizing Guide that will allow you to know exactly what kind of unit you'll be needing. If you have any further questions please feel free to give us a call! Thanks.
Can this unit tie into existing ductwork?
Yes, the indoor air handler unit can be connected to existing ductwork. 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.
Which size system will I need for 2000 squared ft.² house?
Thank you for your question. In addition to square footage, the size of system you will require is dependent upon several other factors. These additional factors include the climate zone the space is located, the number of windows and the quality of insulation. For instance, in the warmest U.S. climates a 4 ton system will cool about 2101 to 2400 square feet. In the colder U.S. climates, this same 4 ton system will cool about 2301 to 2700 square feet. For heating, different parameters apply. In the warmer climates, you will need about 30 to 35 BTU per square foot for adequate heating; In colder climates you will need about 50 to 60 BTUs per square foot for adequate heating. But again, the quality of insulation and number of windows also impacts this range. For more in depth information on sizing, please reference our sizing guide. If you have any further questions, please give us a call.
Can the system be down flow
The MRCOOL ducted heat pump systems are not rated for downflow operation. We do however have several heat pump products from Goodman and AirQuest that do offer a downflow solution (Example: Model #R4H460GKC / FEM4X6000BL). You can find more of these products by visiting the heat pump systems page on our website. If you have any further questions please feel free to give us a call! Thanks.
Bolt to bolt dimensions for the base on the 5 ton condenser unit.
The dimensions of the base for this unit are 42-3/4 inches from edge to edge and 24-1/2 inches from bolt to bolt of the legs. If you have any further questions please feel free to give us a call! Thanks.
