"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."

"After a while of extensive research in finding for the right contractor or construction company to upgrade our kitchen, we decided based on several reasons to go with Landmark construction energy crew and we are so glad we did. The reasons that made us hiring this company were:
-    We felt during the meetings that this company is honest, reliable, focus on making the best decisions for the clients and mainly their passion about what they do and provide.
Although the results of the remodeling that was done by Landmark construction energy crew has far exceeded our expectations and goals. Charlie's professionalism and experience among with his artistic vision was truly amazing. From the moment of listening to what we really want to achieve to the end of the remodeling of the kitchen – not even one item was left uncovered. My favorite feature in the new kitchen is definitely the breakfast area with the gorgeous energy efficient windows including the seating area that overlooks our pool and back yard area.  We really could go on and on with lots of more details and explanations about the attention to detail and amazing design that was done completely by this company, but we rather leave it for others.   Our main recommendation about them is that if you think of hiring someone to remodel anything in your house… Than do yourself a favor and hire Landmark construction energy crew.

"Our Service Tech, Alex Peck, arrived on time to perform the annual check up & tune-up of our HVAC System. He was very professional and following the Tune-Up asked if there was any other items that needed done or looked into that he could take care of. His services were very much appreciated and very professional. Lee"

Energy Efficiency Auditing questions, answered by experts

R-value measures an insulation material's thermal resistance, indicating its ability to resist heat transfer. A higher R-value signifies better insulation performance because the material is more effective at slowing heat flow. The R-value depends on the type, thickness, and density of the insulation material, such as fiberglass, foam, or cellulose. Each inch of insulation typically provides an R-value between 3 and 8. There is no single universal R-value; the optimal choice depends on your climate zone. Colder climates require a much higher R-value than warmer ones to maintain energy efficiency, keep the home warm in winter and cool in summer, and manage costs.

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.

They’ll use more electricity than the average upright vacuum, but not remarkably more. Most power units plug into a standard 120-volt outlet and don’t have significant power demands. You shouldn’t notice an increase in electricity bills. If you have any specific questions about energy costs, ask your installer as you examine purchase decisions. Larger power units will need more electricity for their suction levels.

You'll likely need more than great home staging to sell your home. Now is a great time to get to work on the curb appeal of your home . Hire local exterior painters and landscapers to coat the exterior of your home and bring it new life with some sprucing up.

If you have central air conditioning, it’s fine to run your AC all day if that’s what you want—as long as the AC unit is in good condition. But if your AC runs constantly when you don’t want it to, there may be a problem with your system (like the ones we’ve mentioned above). Window AC units and wall air conditioners aren’t as powerful as central AC, so you should only run those kinds of air conditioners for eight to 12 hours at a time.
