"I had Excellence Electric install a Tesla charger in my garage. The job was difficult and required a replacement upgraded 200 amp circuit breaker with a 60 amp power line pulled through the attic across the house and dropped down into the garage where the Tesla charger port needed to be installed. Raymond at Excellence Electric completed the job on schedule, took care of all of the HOA and city permits, and kept me updated all the way through the process. I can highly recommend Raymond at Excellence Electric with out hesitation for any electrical work needed on your home or office. Kyle Webb Casa Del Sole residence"

"Besides Solar work that they completed at my house, CEB also installed 2 ceiling fans inside house, and removed all interior carpet and put 2'x2' Travertine ties w the thinset & grout, and painted the entire interior of house. They took care of the project clean-up as if it were their house. I researched what CEB can do, and with their Class "B" Contractor license they can build a house from the ground up, and do Home Improvement projects, and pull any required permits from the City. These guys are legit. You will be a satisfied customer working with California Energy Builders."

"We purchased the home energy audit with the understanding that we would be receiving a more extensive analysis of our home energy usage along with possible solutions. Ultimately, the process was more about a presentation for solar panels that anything else, which was not what we were looking for when we purchased the offer. Richard was very professional and thorough in his presentation and presented options regarding areas to save in terms of energy usage but those areas were not as thoroughly explored as the solar discussion. Green Source Energy should be more direct about what the Home Energy Audit entails so buyers can make an informed decision."

Energy Efficiency Auditing questions, answered by experts

To determine the right size generator for your house, you should calculate the total wattage of the appliances and devices you want to power during an outage. List all essential items, note their start-up wattages, and add them together.

Here are some typical wattage requirements for common appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 to 4,500 watts

  • Electric furnace: 5,000 to 25,000 watts

A 7,500-watt generator might be sufficient for essentials like a refrigerator, freezer, well pump, and lighting circuits. However, for high-demand items like a water heater or furnace, a whole-home generator is a better choice. A portable generator may be enough if you only need to power a few critical items.

While home square footage can offer a rough estimate, it is not always a reliable indicator. For reference, here are some typical generator sizes based on square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14 kW

  • 2,500 sq ft: 12–16 kW

  • 3,000 sq ft: 16–20 kW+

For the most accurate sizing, consult a professional who can calculate your home's peak and average power consumption and recommend the optimal generator.

The three levels of home energy audits include:

  • Level 1: Review of your energy bills and home for signs of energy inefficiency and areas for improvement. The average cost range is $0.08 to $0.12 per square foot.

  • Level 2: A level 2 ASHRAE energy audit costs $0.12 and $0.35 per square foot. In-depth analysis of your energy usage and provides a report of cost-saving changes.

  • Level 3: Comprehensive analysis and detailed recommendations for ways to improve your home’s energy efficiency. A level 3 audit costs about $0.36 to $0.50 per square foot.

There is no blanket figure for a residential home’s electrical load, since load varies by the size of the home, how many appliances are used, and the efficiency of their electrical systems. Typically, however, it’s safe to assume 40 to 60 amps is the average electrical load of a residential home. 

Heat pumps transfer existing heat instead of generating it, using less energy. Compared to baseboard heaters, they can reduce heating costs by up to 50% and provide efficient cooling, lowering electricity bills and carbon footprint.

A good SEER rating for an HVAC system is typically between 15 and 20. However, minimum requirements vary by location; HVAC systems in northern states must have at least a 14 SEER rating, while those in southern states need a minimum of 15. For the highest possible efficiency, look for units with a SEER rating of 21 or higher. It's important to remember that a SEER rating represents the maximum efficiency a unit can achieve, not the level at which it will operate at all times.
