OLMO 9,000 BTU 230V Ductless Mini Split Air Conditioner & Heat Pump – 18.5 SEER2 Inverter System – Wall Mount Single Zone Cooling & Heating – Pre-Charged

I've got a small, old house with no central HVAC. So, it's heated and cooled with split units and window units. This is a huge step up from a heat pump window unit for not much more money. Obviously, this is a lot more difficult to install, but the inclusion of a defrost cycle and its quiet operation make it vastly superior.As to the installation, I did the whole thing myself. I'm no HVAC pro, but I have a vacuum pump and manifold gauges from automotive work. I did have to buy a split unit-specific adapter fitting for my gauges and some electrical stuff, but otherwise what was included was turn key.The instructions could be a little clearer on the relationship between line length and pre-charge amount, with "standard" lengths listed for different regions that are different from the included pre-flared lines. To avoid stressing over the quality of my flares, I went with the full length lines as shipped, vacuumed them out for double the recommended time, removed the gauges, opened the valves at the outdoor unit, and let it rip.It runs great, ice cold on A/C and nice and hot on heat. The remote control is the same as my existing Carrier units, so I can control them all with the same remote.Highly recommended.

It came in good condition and wasn't too hard to install. I was able to do the installation with no help, but I would recommend having a helper to mount the inside unit. Hardest part was carefully bending the copper tubes between the indoor and outdoor units to keep them hidden behind the indoor part where they go through the wall. If you don't hire an HVAC tech to start the system up, you'll need a vacuum pump to evacuate the sytem before opening the valves on the outdoor part to release the charge into the rest of the system. I bought one of the cheaper vacuum pumps from Amazon to do it myself, and used it on this system and another. The unit is very quiet and quick to bring my 12x20' office down from 80° to just above 70°. Since it is a heat pump, it has condensate drains from both the inside and outside units.

Only installed a week ago, but it functions like central unit, heats & cools the entire 500sq ft area comfortably...since we are transitioning from winter to Spring I've tested out both modes and it performs effectively!

Excellent product

A professional team, consisting of HVAC, electrician, and drywall contractors, collaborated to install the unit in an attic room lacking ventilation. Although there were additional expenses for a longer cord due to the provided short tubing, the unit is now functioning well. The electrician also installed a dedicated power source, which incurred extra costs. On the positive side, the unit is user-friendly, and the washable filters contribute to cost-saving benefits.

Delivered in one day, everything you need to install comes with it, very very quiet, excellent product.

Worked well for a while, but eventually stopped blowing cold air. Had a repair man come and he found that there was a hole in the outdoor unit which meant all the refrigerant leaked out. The repairs were more than the unit itself. DO NOT BUY.

Easy set up works great
