"Chris came by for a normal AC tuneup and as he was finishing up, we told him about some issues with our dishwasher and master bathroom sink and asked if he knew a plumber. He took care of both our problems right then and there! I’m not sure there’s anything he can’t fix. Chris is our go to guy for EVERYTHING ac/furnace/plumbing and he should be yours too!"

"They simply did a great job. I had them remove the old insulation, install new batt insulation, and add radiant barrier in my attic. Now my attic and house are a whole lot cooler. It is noticeably cooler in the house. The person who contacted me was Dustin. He was very professional and did a great job explaining things to me and laying out my options. The crew, which included Aldo, Roman, and Aaron were very professional and respectful to the care of our home and performing their job. I would definitely recommend and am willing to rehire them again for possible future projects. Thanks guys."

"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."

"Professional, Professional, Professional? did I mention Professional. I was and am extremely happy with the solar system provided by Golden West Energy. Scott and his crew paid attention to the details and cleaned up the job site every day. Permits and inspections happened quickly. I had a friend who contracted for solar panels on his house 3 or 4 months before I even gave Golden West Energy the approval to get started. My installation was up and running with all approvals 3 weeks before his system was allowed to be turned on. If you are looking for a professional installation I would not hesitate to recommend Golden West Energy as one of the companies to give a shot to. If I had to do it again - they would be my choice?.
They turn the Golden Rays of the sun into power - Go Golden West Energy - 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."

Energy Efficiency Auditing questions, answered by experts

Window AC units use a fair amount of electricity, but significantly less than central AC systems. Because they are more energy-efficient for cooling individual rooms or small spaces, their usage is comparatively low. On average, a window AC unit consumes between 500 and 1,400 watts, while a central AC system uses over 3,500 watts—meaning a window unit uses about one-third of the energy. This typically translates to a monthly running cost of $15 to $40, although this can vary depending on external factors.

Motion-sensor lights use one watt while on standby and five watts while turned on. They’re usually on for one hour over a 24-hour period, bringing the total wattage to about 28 watts per day. LED lights use around 6.5 to 8 watts while on. If you leave an LED light on all night, with night ranging from 10 to 14 hours, you’re looking at using 65 to 112 watts a night. You can minimally cut your wattage in half by switching to a motion-sensor light.

You can save money on heating oil through a combination of improving home efficiency and smart purchasing strategies.

Home Efficiency and Usage:

  • Improve Insulation: Ensure your home, especially the basement and attic, is well-insulated and sealed against drafts to prevent heat leakage.

  • Manage Your Thermostat: Use a properly calibrated and programmable thermostat. Lower the temperature by a few degrees, particularly when you are away from home or asleep.

Purchasing Strategies:

  • Buy in the Off-Season: Order heating oil during the summer months when prices are generally at their lowest. This strategy is most effective if you have a large primary tank or a separate storage tank to accommodate bulk deliveries.

  • Consider a Delivery Contract: Some companies offer contracts with a set price for the term. This can lead to savings if market prices for oil increase, but you might pay more if prices drop.

Yes, a dirty air filter can cause a higher electric bill. That’s because clogged filters make it harder for air to flow through your HVAC system, which forces it to work harder and use more energy. According to the U.S. Department of Energy, replacing dirty filters can save you between 5% and 15% in utility costs.

After you receive your audit and report, review the findings and determine which of the prescribed changes you want to make to improve your home’s energy efficiency. Start by contacting the type of professionals recommended by the auditor who can help you remedy the issues discovered during the audit. Prioritize the projects by urgency, importance, and budget. Then, gather estimates from several professionals, remembering to verify any necessary licensing and experience information.
