OLMO Sierra Single Zone 36000 BTU 19 Seer Mini Split AC/Heating System Pre-Charged Inverter Heat Pump

Good value, first one I installed 5 years ago,I have installed many this brand and no issues. Many of these are advertised that it is do it yourself installation and can be but i dont recommend purging system instead of pumping lines down and most of these are bad for leaks in linset connections..I use lock seal on fittings and line test with nitrogen to 350 lbs.. I pump down lines to -30lbs with vacuum pump. Unit is factory charged with r410a freon good for 25 feet or so of lineset length.Lineset can be shortened or added to with flare fittings etc or you can roll up if you have to. Foam lineset cover won't last long outdoors. Use a plastic cover or rubatex. I also used wall brackets for outside unit. You can use pad or block to sit on also. No warranty if you install yourself unless you are hvac certified. Very quiet , air was pretty warm at coldest I've seen down to bout 3 degrees. Most of these are identical at this quality just have different labels on them. If installed correctly and sized accordingwill do excellent and pretty efficient even with just 15 seer models. 600 square ft per 12000 btu with decent insulated living area usually bout right for sizing. Rinse out filter once a month and set temp where you comfortable and it works great.

Easy instructions to follow

So far it's great, easy to install

The customer service department and distribution center is out of Doral Florida. Whenever you call as to an issue, the warranty department will demand a licensed outsourced AC company. Though the split system is reasonable in price but the outsourced installation and or diagnosis gets expensive. If you have multiple investigative needs, as I did, the labor exceeds the cost of the unit. Comfortside aka Olmo uses every trick in the book to not cover the device. I had to resort to the BBB on two occasions to get a resolution. On the first unit failure I was successful in coverage yet on the second issue, a part that was covered, Comfortside decided that the part was not covered by warranty claiming the unit was not under warranty. This was strange especially they replaced the part under forced warranty the first time. The take away is that Comfortside is argumentative, rude, abysmal customer service. They intentionally work out of the state of Florida due to the laws being more supportive to the corporation thereby allowing for more consumer support subjectivity. 1 Stay away from companies operating out of Florida, 2 don't buy Olmo the ratings given here are not accurate. You are better off buying a competitors system than from Olmo/Comfortside.

The whole unit seems to be of decent quality, it cools my two car garage really nicely and you can barely hear it running. The controls are pretty straight forward and easy to figure out with out to much problem. Only thing I would change is the wiring instruction picture was terrible and the signal wires weren't numbered for which socket they belong to so just have to remember where you mounted each colored wire on the indoor unit and match them up, not a huge deal but just one more step you have to take.

The mini split is a good value easy to install also very quiet while running. In order to have the warranty the line set will need to be installed and put under vacuum testing for leaks by an hvac tech. I would recommend this product we r currently using it in our basement in central Indiana

The olmo 18000 mini split works perfectly. I got because a couple rooms were a little warm while the rest of the house was cool. It seemed like the ac wasn't keeping up July 2024. I got this to supplement my unit. The unit hardly runs at all now.The unit pulls 15 to 20 amps while the mini split only pull about 7 amps. Hope to see this reflected I'm my light bill.The line set was 15 ft and was branded as cooper and hunter. Should be high quality.Did self install in about 3 hours.

These are still running flawlessly after 2 years in a poorly insulated home. They provide adequate cooling and less than adequate heat. I would only use these to supplement your forced air/boiler or other heating systems unless you live in a climate with extremely mild winters. Sub-freezing temperatures are where this thing struggles.
