How many BTUs do I need for my ductless split?

Please Note: Mini Split Systems must be installed by a licensed Contractor with an EPA Refrigerant Certification to qualify for warranty.

(BTU ratings are estimates only, based on 10ft ceilings, with great insulation and windows. Some factors may alter this calculation: lack of insulation, heavy sun, excessively hot regions, & tall ceilings)

9,000 BTU       350 sqft12,000 BTU     500 sqft18,000 BTU     750 sqft24,000 BTU     1,000 sqft30,000 BTU     1,250 sqft36,000 BTU     1,500 sqft

Make sure you install a unit that is going to properly cool your square footage. An over-sized air conditioner is actually less effective — and wastes energy at the same time. Air conditioners remove both heat and humidity from the air. If the unit is too large, it will cool the room quickly, but only remove some of the humidity. This leaves the room with a damp, clammy feeling. A properly sized unit will remove humidity effectively as it cools.

Which Line Set Kit Do You Need?

This unit uses a 1/4" x 1/2" line set. These are sold separately, and you can choose from our 15 ft, 25 ft, and 50 ft lengths. Length is dependent on the needs of your project and how you will set up the system (distance from condenser to indoor air handler).

Can I install this myself?

While installation of a ductless split is much easier than a central air system, it’s still much more advanced than installing a window unit or portable. Furthermore, the manufacturer warranty is only valid if a licensed professional does the installation. So while it is possible to do the installation yourself, we strongly recommend you hire an HVAC professional in your area.

Is this backed by a warranty?

Yes, it comes fully backed by a manufacturer's warranty, and ComfortUp is an authorized online seller of these systems. Our customer support team will provide assistance should you ever need to file a warranty claim with the manufacturer. Please be aware that only systems that are installed by a licensed HVAC contractor are backed by the warranty. Proof of licensed installation is required. The receipt/invoice from the contractor should be sufficient.

The unit installed easily. Its a good quality product, is quiet and efficient. I replaced another unit with this Gree product. It is a better made and better quality unit than what I had before. Gree was also recommended by A C professionals I spoke with and use for my A C work in my home.

We purchased this system because it wasn't getting cool enough in the master bedroom. After it was installed now we can controlled the quality of life without having to cool the entire house. The seer rating being at 25 makes this a very efficient unit and is a low cost item to run. We are soo glad that we purchased it.

Incredibly pleased with this unit, my first mini-split. Purchased on the advice of a landlord who installs a lot of Gree mini-splits. Very, very quiet with the gentlest of a breeze-- not at all like some roaring window unit. My only complaint is that you don't really feel the air moving as much as I would like so I bought a little wall mounted fan to go next to my studio desk. The Terra is remarkably efficient. Even though my studio is not well insulated, I can leave the temp set at 81 degrees and it will cool off almost immediately when I lower it to 72. Love having a remote control too. Shipping was as easy as buying from Amazon and the entire unit arrived on one really well-packed pallet that the shipper off-loaded onto my driveway with a small hand-operated forklift.

No damage in shipment, it arrived in 5 business days. It was easy to install (read the instructions first) I had a local HVAC company to purge and evacuate the lines. The unit works perfect. Very happy with my purchase. Will probably purchase another unit next year for the rest of my house. My next door neighbor came over for an inspection now he is going to order one for his home. The staff at Comfortup is fantastic! Thanks, Tim

I needed a split unit for our IDF room at our school average temp was 90 degrees The Gree was easy to install and does a real nice job of cooling. One of my reasons for choosing this unit is that its capable of operating outside ambient to 5 degrees, that I need due to the heat load of the room even in the winter months. In about five hours we had the unit mounted, wired plumbed, pumped down and cooling. Dave
