HVAC (heating and AC) question
« on: August 14, 2016, 11:53:24 PM »
Had an old steam heating system, boiler broke. Was planning on replacing with hot water boiler, baseboards.

Now reconsidering, leaning towards forced air and central AC< which contractor says will only cost a little more.

Other options include staying with the hot water heatin plan and adding central AC in addition (though a lot more expensive that way). or adding split units ( 1 or 2 would do it), or sicking with plain old window units.

Curious to hear your thoughts.

IMHO forced air heating is the worst thing ever. Only marginally better then no heating at all.

Is forced air the same as ductless heat? What's the issue with it?

Ductless is probably split units...forced air is with ducts, the heating version of central AC.

I have forced air with no issues. Especially like the fact that I was able to add UV lights as an inline air purifier. Also added a humidifier and zoning and have been very pleased with the result.

I'm guessing your issue is that forced air is too dry, a humidifier can usually be installed for ~$500.

I've heard that the humidifiers have a tendency to leak...?

I did a fair amount of online research (I haven't installed one myself yet, just moved in this past Winter) and found no downsides, I didn't speak to anybody that actually did it though.

There is nothing wrong with forced air heat.

How does baseboard heat filter out some of the dirty air you are breathing?

I have a hydronic heating system connected to my central. No problems and no dry hot air.

From a quick google, hydronic heating seems to be either hot water baseboards, or radiant (underfloor) heating. How does that connect to the central AC?

Or am I missing something?
