Currently I live in a house with 3 housemates. The house was built in the early 90s and is about 1,800+ square feet. One of the housemates owns the house and has the responsibility of bills, bills, bills and taxes (yuck). What came into discussion late this summer was the wretched PG&E bills, which some might say is as hard a pill to swallow as taxes. It is safe to say that in the city of Fresno, residents are most dependent on their air conditioners around the June through August summer months. Our bill was no exception as we experienced an average of $278 a month with August reaching as high as $320. I sat with the homeowner in awe as to wonder what on earth we were doing that the bill was so high. After all, the house is empty 5 days a week between 8:30 am and 5:00 pm and we felt that was a significant amount of time to not be using any electricity that the bill shouldn't put us into traumatic shock.
After asking the homeowners several questions about the house: water heater, air conditioning, fridge, dishwasher, washer and dryer, windows, insulation and anything I could think of, I finally contacted my local Central Valley Energy Tune up (www.cvetu.com). This FREE service provides education to homeowners about energy savings opportunities in their homes through a variety of free energy efficiency service offerings. I requested that we have the comprehensive “Whole-House Home Energy Survey” option which would include their inspection of the entire house including air conditioning system and attic. While the homeowners have not received their detailed reports, the “energy inspectors” did have input that provided some insight into how they could save on their energy bill.
First, the house faces south-southwest, so that means the 2 bedrooms that face the front of the house have direct experience with the Fresno summer sun from about 3:00 pm – to 6:00 pm where the average temperature this summer is in triple degrees side of the thermometer. So we have two rooms that have “sauna-like” temperatures that the house has to work harder to cool down. The proposed solutions: a) keep the door open so hot air doesn't stick; b) get low emissivity windows.
The second opportunity was definitely a shock and considering that I personally am not a homeowner, I find it interesting to discover that there lazy contractors did half of the job with the insulation. (See photo below)
Just randomly, the in the front part of the house, where the sun faces, the thermal imager registers that there’s no insulation. Hmm. Homeowners had no idea.While I am all for energy efficiency and insulation is one method to get there, I am baffled at the randomness and sloppiness of the contractors/installers themselves. Why would they all of a sudden just not finish insulating the house? We’ll never know.
So here’s the lessons learned. First, Central Valley Home Energy Tune Up is FREE. You really can’t lose having an inspector review your home and receive a detailed report providing you with what’s going on with your home. Second, contractors suck.
