Replaced my A/C this weekend, results of downsizing by 1/3.

Recently my 13 yr old Carrier A/C devolved a leak and I chose to replace the system rather than track down the leak and repair the coil. I had been reading about doing manual J calculations and how contractors are scared to death to undersize. I had been talking to co-workers about this and it's an uphill battle getting them to think different than 1 ton per 500sq ft. So I decided to take confidence in correct sizing and "put my money where my mouth is" and install a 2 ton sized…

Lead Generation Services for Home Energy Professionals?

Home Energy Pros,

Has anyone used a lead generation service that they have had success with? 

What are your general thoughts about lead generation?

At, we think that linking educated consumers with home energy pros is a much needed service.  Of course there is Angie's list, but that is a paid service and I dont think it's that strong in Home Energy services.

Why Isn't the South Green? Or is it?

Everyone is seeking the elusive killer app that will revolutionize energy. Most expect it to be a high tech gadget, or new form of generation or a way to finally store mass quantities of electricity.

Not anthropologist Susan Mazur-Stommen. She’s looking in a completely different place: inside our heads, or more specifically inside the heads of those who live in the Deep South.

Mazur-Stommen, who is the director of behavior and human dimensions for the American Council for an…

Mechanical Ventilation

Mechanical ventilation of your home is a good idea. That means a fan running 24 hours a day 365 days a year. It provides a means of reducing indoor air pollutants and improving IAQ. It’s good for you and your whole family. We have a cute saying “dilution is the solution to indoor air pollution”


But aren’t you supposed to show me ways to save money and use less electricity? I don’t get it

Calculate How Much More You're Spending By Not Using LED Light Bulbs

Early last week, as I walked into my condo's elevator, I noticed something different; it was really bright in there now. After I pressed my floor's button I looked up and saw that all 8 of the PAR20 halogen light bulbs were replaced with new ones that clearly weren't going to let anyone hide behind any areas previously darker with the old lights.


Curious, I emailed the landlord and did some research on kinds of brighter light bulbs. After about waiting a week for my landlord…

Window Film Gets Respect in California

Recently the California Energy Commission (CEC) put window film on the fast track to get it into the new building code—to be effective in 2014. As the first state in the nation to place window film in the next building code, California has officially recognized window film as a legitimate, cost-effective energy saver.

This change in thinking is due to recent reports and studies that show just how effective window film, a thin polymer adhered to the inside of glass, is. One such study…

10 Ways to Cool a House Without Air Conditioning

Sleeping on the front porch after a hot summer day was a straight out necessity. The upstairs of the 1940’s farm house had turned into a sauna and sleeping in the upstairs bedrooms was not possible. Even after the sun went down, the upstairs seemed to get hotter. Let's look at some ways to cool a house without air conditioning?

Now that I spend time trying to figure out how a home can be more energy efficient, I think back to those hot summer days and wonder two…

Where do the presidential candidates stand on energy efficiency?

We know that what a political candidate says during a campaign often differs from what the eventual office-holder does. We also know that candidates choose their words carefully to give themselves wiggle room for modifications in course.

So we listen for innuendo and subtleties when candidates talk about our special interests. What kind of qualifying language do they use? Are they truly against X, Y and Z, or only under special circumstances?

 Below are some quotes on energy…
