We've been talking for a long time about the importance of energy efficiency in the home as a key way to both save money and be green. From discovering phantom energy leaks to installing proper insulation, there are numerous little pieces of the puzzle that can help or hurt energy efficiency.

Recently I noticed that my refrigerator was not keeping things as cool as they should be. I had to turn the settings to the coldest just to make due. Worried that I'd have to call in a local Brooklyn HVAC contractor to diagnose the problem, I headed to the Internet to see if I could figure It out myself.

I found a tip over at This Old House that helped me discover where the problem with my fridge was. They explained that over time, the rubber gasket that seals the gap between the door can become worn out, allowing cold air to escape and undermining the efficiency of the unit. To find out if the gasket is not working, just close the door on a sheet of paper and try to pull it out. If there is no resistance, the seal is broken and the gasket needs to be replaced.

Fortunately, a new gasket is simple to install and only costs $90 at most, so it will be an easy repair for me to do myself.
