Participant“The central AC cycling on and off is not excessive, IMHO — about the same as my AC here in San Diego.”
Yes it is excessive, otherwise you wouldn’t be complaining about the humidity.
A good residential unit will run the fan at a lower speed for a longer duration when dehumidification is needed. Variable speed fans and 2 stages of cooling capacity have made dehumidifying residential applications really easy. Your unit either isn’t set up correctly, or it’s a plain jane old school single stage single speed unit doing 80% sensible heat and 20% latent heat just like it was designed to do. Sized correctly you can see what happens with a higher latent and lower sensible heat load. Oversized in San Diego has no consequence. Throw in humidity and game over.
Get it set up right, get some control over the fan speed, or get a unit to suit the application.I should add not only will you be comfortable with a 2 stage unit you energy usage should go down as well. The local utility may have a rebate or incentive. Not sure if the fed has a write off this year, they did last.

Participantok that makes sense. You had already said essentially it’s as easy as it gets, I just lacked the imagination. Sounds like good deal all the way around. I’m even impressed by the price of the equipment, a couple years ago a 13seer 90% would cost more than that.

Participant4200 is so cheap it sounds to good to be true is all. Theres also about $500 in miscellaneous materials plus a permit coming out of that. Even if it’s like 10′ from the furnace to the condensing unit, 30′ from the electrical panel to the condensing unit, and theres already a slab to put the condensing unit on theres still around $300 misc. A drain line has to be run (of course), the furnace condensate is acidic and will eat metal pipe, concrete, and kill plants. Your metal/ceramic/asbestos combustion gas vent pipe must be completely replaced with a pvc one. I wouldn’t do all that work for 800 bucks but theres always someone hungrier. If your existing thermostat doesn’t have cooling or a 2nd stage of heat, if you need more return air to get the required cfm for cooling, thats not a freebie, thats a required part of the job. Hopefully theres enough insulation on the ductwork that it doesn’t sweat in cooling.
As far as licensed and bonded, you basically buy a license in CA it has nothing to do with competence, the required bond is $1500 (I think), people use other peoples licenses all the time, and it’s not like he’s got the electricians license to run the electrical anyways. Not that a permit was even going to be pulled. We’re lucky we’re in a coastal zone and a Ca title 24 duct leakage test isn’t required.Participant4200 is so cheap it sounds to good to be true is all.
