So what do you do when you live on a boat and there’s a heat wave coming?
You clean the A/C filters of sediment and make sure things keep as cool as possible.
Like most boaters, we have what is called a “reverse cycle” air conditioning system, which can heat or cool the boat. Raw water from the Bay flows through a filter, a pump, and then a condenser which pulls the “Cold” out and sends the “Hot” overboard. (Don’t ask me more than that, thermodynamics was not my strong course in college.)
Unlike most boaters, we’re docked in 6′ of water (at low tide) that always seems to be full of sediment. Couple this with the fact that our intake is near where the keel mounts to the hull, which is only about 3′ off the extremely mucky bottom of the marina, and we suck up a lot of dirt! So I clean the filters often.
And before a heat wave, I clean them again.
