This company is a joke
This company is a joke. I replaced my 18k BTU wall unit with a 22k BTU mini split. The difference is ridiculous. This mini split doesn't push even close to half the cold air my window/wall unit pushed and it's 4k BTU higher. And I also rented the kit from them with the micro meter. Sucked the system down to 400 micron. Recommended 500 or less. Left the gauges hooked up for 30 minutes to ensure no leaks. Della is complete trash. But here is the real kick in the ass I bought it for the good warranty. You can not even register your warranty without a certified HVAC license# even tho you rent the kit for an extra $300 . Example of how shitty the unit is. My wall unit $18k BTU would cool my living room and kitchen in 20 minutes down to 68° f in 20 min. This 22k Della unit takes well over 4 hours to get the room to 68°. I highly recommend nobody buy this brand product. There is way better options for less money that are twice as efficient.
