And by not doing so, they are missing out on potential business and falling farther behind the leaders of the industry. What I mean by this is that, over the past two decades, understanding of the indoor environment, indoor air quality and the interrelation of building systems has increased dramatically. Think AHRAE 55-2010, and the factors effecting human…

Selling AC Retrofits - Notes from the field.

First I talk of safety. I mention old furnaces and CO possibilities, etc. This will usually make them sour up a bit because it is slightly a sales pitch.

Then I usually talk to homeowners about the hot and cold rooms. This is a big button and an easy one to push and get them talking. This adds to the sourness but gains…

Thanks to the federal tax bill signed into law in December, there are still energy tax credits available for 2011. That's the good news. The not-so-good news is that the amounts available in 2011 have been reduced for certain improvements. From 2009 through 2010, homeowners were rewarded with a 30% tax credit for making their homes more energy efficient ($1500 maximum credit). For 2011, homeowners will receive only a 10% tax credit for home energy efficiency improvements ($500 maximum credit).… Continue
