"We recently had Mega Power Electric Inc install a solar system and panels. The President and provided excellent communication all the way through the process. He even met with us after installation to explain the almost incomprehensible PG&E bill. Although not the least expensive bid, his was competitive and I felt he was as interested in educating me about solar and the various types of panels and inverter systems as he was in selling a system. He demonstrated how the array of panels would meet our energy needs and as opposed to some of the other companies, wasn't selling us more than we needed. We are very satisfied with our solar system and I highly recommended Mega Power Electric Inc."

"I’m very pleased with Excellence Electric. The owner, Raymond Lezama provided excellent customer service. He thoroughly inspected what needed to be done and gave me a couple of options. He explained the differences between the options and gave me his recommendation. The work was done quickly and thoroughly. And the price Raymond quoted was very reasonable! Great work Raymond. Thank you!"

"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."

"Acvolt Electrical INC. is very professional and efficient when they work. They were able to come in, diagnose the problem, and fix the problem by the next day (they had to order parts). They were highly knowledgeable and easy to talk to when explaining what was going on. I highly recommend them!"

Energy Efficiency Auditing FAQs, answered by experts

Electric bills tend to be lower in spring and fall because people use less electricity during these seasons. Milder temperatures allow for less use of heating and cooling, unlike during winter and summer, which usually bring more extreme temperatures.

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.

Smart home upgrades can be worth the money. Several upgrades, including smart thermostats and ceiling fans, can help reduce your energy bills. Others make life more convenient, freeing up your time to do what you love (or get more work done). And some smart home upgrades, such as entertainment systems, simply make life more enjoyable. All are worthy causes.

While you can perform many routine home maintenance jobs yourself, it’s often a good idea to bring pros in for certain tasks. HVAC maintenance, fireplace and chimney inspections, foundation repairs, and roof inspections and repairs should be handled by professionals who know what to look for and can safely perform repairs. You may also find it helpful to hire a local house cleaning service to help with deep cleaning.

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.
