Questions and Answers

Customer Questions
How to I determine what size of split system I need?
Hi, please give us a call and we can help you determine exactly what system and parts you'll need. We can also answer any other questions you may have during the searching and purchase process! Thanks
I was quoted that I need a 16 seer conventional ac what size would I need for a mini split
The tonnage you were quoted for the traditional AC would be the same tonnage you need for a mini-split system.
Can this unit be installed in the attic of a ranch style house?
Thank you for your question. The indoor air handler unit could be installed in your attic, however, it can only be installed in the up-flow position. Also when considering an attic installation, the quality of insulation plays a factor in the efficiency of your system. For more assistance, please give us a call at 1-888-377-2850.
Do you sell a top and bottom plenum? Can you give me a size for 3 Ton 18 SEER MRCOOL Universal Series Heat?
Thank you for your question. You will need bottom plenum that will match the dimensions of the furnace which are the following: 21-1/4" x 21-1/4" x 48-1/4". For the top you will need 11-5/8" x 20". We do have plenum options available. For assistance in finding exactly what you need, please give us a call at 1-888-376-5487.
Are there mounting sizes available for the condenser unit?
For mounting the condenser on the wall, we recommend this Diversitech mounting bracket for condensers. For more assistance, please give us a call at 1-888-377-2850.
My unit is gas furnace, so if I purchased this, it can be converted using only electricity?
Yes, you would use the air handler as heat, with the back up heat kit if needed. If you have any further questions, please call us and we will be happy to assist you.
Is 4 ton 18 seer Mr. Cool enough for 2000 sq.ft?

Downflow conversion?

Where are they manufactured?
MRCOOL is based out of Kentucky however most of their mini-splits are manufactured in China.
Do you carry a DIY mini split that would work for my shop? 30x45 with 14’ walls and 16’ total height at center.
Thank you for your question. Yes, we have several options that would be great for your needed application. However, the size of mini split that you will need is dependent upon your climate zone and the quality of your shop's insulation. Please reference our Sizing Guide to help you determine what kind of unit you'll be needing. If you have any further questions please feel free to give us a call.

If the homeowner buys the equipment and puts it in their self can they get the 10 year warranty
The MRCOOL Universal products are not considered to be "DIY" like many of their mini split products. In order to receive the 10 year warranty for this product MRCOOL states that it must be installed by a professional installer. If you have any further questions please feel free to give us a call! Thanks.
Can I use my existing 3 ton evaporator coil and furnace?
You are able to do so as long as the tonnage stays the same and the same refrigerant is being used. However, you are not able to swap out a Goodman condenser with a MRCOOL condenser. MRCOOL cannot work with existing furnaces and coils; you would need to do a full system swap and get the MRCOOL air handler as well. Their air handler has an integrated coil inside as well as a blower motor, which requires a MRCOOL condenser to be matched with it. If you have any further questions, please call us and we will be happy to assist you.
