I’m going to tell you a little story. Our house has 2 central air/heating units and I keep a service and maintenance contract on them. We have removed all the carpet in our house and replaced it with ceramic tile. The AC guy comes over to change the filters and always comes out of the attic laughing and says he can always tell a house with no carpet because of so much dirt in the filters. Guess where it stays in carpeted houses.
Had A/C when we lived back east. I will never live with A/C ever again. As someone who’s been in the contracting business for over 30 years, I still hear stories of “new” things being found in duct systems.
Worst we had was dead possums, freshly maggoted to the point they were like soup.The smell……..
Mostly bullshit.
New home construction in the US has required an HVAC (heating, ventilation, air conditioning) system in order to secure a building permit for at least the past 30 years.
Further, no one in their right mind will ever buy a home that does not have an HVAC system unless it is a fixer upper and sold at an extreme discount. It is very expensive and difficult to install an HVAC system after the fact.
Mikey, above, is right. In the absence of an HVAC system all of that stuff contained in the return air duct in the pc would be inhaled by the occupants, proving that the systems have benefit beyond just conditioning the air.
More than 70% of residential structures in the country have no central HVAC systems.
I don’t know where you get your figures, but they are not required by code in most jurisdictions.
In fact, code only comes into play when you install a system.
And you are much healthier without recirculated air.
We have bare oak floors in my house, with throw rugs we can take out to the back and beat the crap out of them.
Thanks to my allergies, I installed an electrostatic precipitator in my furnace/AC unit. Replaced the old oil furnace with a 98% efficient gas model – did all the work myself because it ain’t too hard. Well except for some sheet metal plenum necessary to make up the difference in height, and they were literally a block away! Hundred extra bucks, total cost was about $1200 bucks. That was 8 years ago.
