Looking for a NYC metro area fresh air systems contractor
我正在购买房屋，下个月关闭。它于2004年建造的相对较新 - 但没有任何特殊的绿色功能。我希望从新鲜的空气系统开始逐渐改变这种情况。
I am interested in getting an assessment for air quality for fresh air exchange and consistent year round humidity and then taking the necessary steps if I need to install a ventilation system (exhaust-only, ERV, HRV, etc). The house currently has forced hot-air (no humidifier) and central AC. I know the ERV/HRV systems take special knowledge the average heating/cooling contractor would be unfamiliar with – does anyone know any resource to find knowledgeable contractors (I’m in Central NJ). I am thinking possibly given the size (smaller 2 story 3 bedroom 2.5 bath) maybe I can just get a ventilation only system if an ERV/HRV isn’t worthwhile (maybe a Panasonic or Broan Smartsense ventilation system).
Some other things I think I should fix right away are an attic fan (doesn’t have one) and maybe a whole house carbon water filter system and maybe a reverse osmosis filter in the kitchen (any recommendations for brands and models?). Any cost effective green improvements you would suggest to start with (and if so, contractor resources I should look to in this area)?

J.M.,
问：“您建议从一开始有任何成本效益的绿色改进吗？”
A. My usual advice: hire a home-performance contractor (someone with a blower door) to conduct an energy audit. Most homes benefit from air-sealing work and added attic insulation.
无论您做什么，都不要安装阁楼风扇。阁楼迷使用的能量比节省更多的能量，有时是危险的（因为他们可以使房屋抑制足以引起热水器和熔炉以产生背景。
我没有想到阁楼中的整个房屋通风风扇 - 我谈论的是保持空气空间在阁楼通风中的小型活跃的排气风扇 - 他们不使用太多动力，可以跑出小太阳能电池板：http://www.broan.com/products/lifestyle/powered-ventilation-options-214161b1-6a0a-4c84-94b0-1d300c1815b4
房屋确实有阁楼玻璃纤维绝缘材料，但我不知道细节。
J.M.,
My advice is the same: you don't want an attic fan.
（顺便说一句，您将其倒退。
Whole-house attic fans = good.
较小的阁楼风扇过去可以通风阁楼=不良。）

谢谢Martin, can you recommend home-performance auditors or a reference site for them? I know someone who had one done but all they did was use an IR camera (no door test) and didn't really help the home owner with concrete suggestions for improvements and contractors.
I'm more interested in fresh air systems as I want good indoor air quality and comfortable humidity levels in the wintertime when the forced hot-air system is running - that's my primary concern.
谢谢
JM,
I'm hoping that a GBA reader who lives in New York City will see your question and suggest a contractor.
Here's the problem: If you consult a surgeon, it's fairly likely that you will be told that you need surgery. If you consult a yoga teacher, you may be told that all you need is yoga.
You wrote, "I want good indoor air quality and comfortable humidity levels in the wintertime when the forced hot-air system is running." To achieve that, you need a whole-house approach. For example, if your house is dry during the winter, an inexperienced HVAC contractor might recommend a humidifier, when the best solution is to reduce air leakage into your basement and out of your second-floor ceiling.
