I have had two different HVAC contractors come to my house and quote me on installing a 9,000 btuh, cooling only Mitsubishi mini-split.
This will be installed in a basement home theater. The inside unit will be installed at ceiling level putting it right at grade.
One contractor wants to drill a hole through my slab for the drain and the other contractor wants to put in a condensate pump. I have a deep sink in the basement about 20 feet from this room and a pump there to drain this sink. I am not whether the condensate pump on the mini-split will pump into the deep sinks or directly outside the house. I failed to ask the contractor before he left. I do live in a cold climate, outside of Rochester, NY.
My house has excellent drainage. In fact, I have a sub pump pit that has never had a pump in it and never even a drop of water. My high efficiency Lennox Pulse furnace has its drain going through the slab.
What are the pluses and minuses about these two drain methods? Can a mini-split be drained directly outside? Are there other drain methods?
