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.

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.

Downflow conversion?

Thank you for your question. This unit is specifically designed as an up flow system. However, you may want to check with the manufacturer or for assistance in finding a system that will work from a down flow installation, please give us a call at 1-888-376-7450.

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.

Do you have a 2-ton 18 SEER unit ?

We currently have the 2-ton 20 SEER Heat Pump system by MRCOOL. 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.

What is the recommended wire size for power supply cord for the air handler unit?

The gauge of signal wire should not be less than AWG18. It’s recommended to use AWG18 power cords as the signal wire. If you have any further questions please feel free to give us a call! Thanks.

Yes, this ducted heat pump system can operate in both heating and cooling. If you have any further questions please feel free to give us a call! Thanks.
