"We needed to replace our old HVAC system, and the entire process was smooth and stress-free. The crew was knowledgeable and gave us several options that fit our budget. The installation was clean, quick, and professionally done. Our home feels more comfortable than ever, and our energy bill is already lower. Five stars!"

"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."

"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."

"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.

Energy Efficiency Auditing questions, answered by experts

While some aspects of an appraisal, such as comparable properties nearby, are out of your control, there are several steps you can take to potentially increase your home's value. Make any necessary repairs and upgrades before the appraiser's visit, as they can only value what is currently part of the home, not its potential. Examples include renovating older areas, updating landscaping to boost curb appeal, and staging your home. You can also provide the appraiser with the cost of recent upgrades, which may increase your home's value by about 50% or more of what you paid for those improvements.

R-value is calculated by dividing the thickness of an insulation material by its thermal conductivity. The material's composition and density influence thermal conductivity. Materials with lower conductivity values provide better insulation. The higher the R-value, the better the material is at insulating, helping homeowners select insulation that meets the energy needs of their climate and home layout.

Yes, pros suggest units with high EER ratings for energy savings.

It’s not recommended to turn off your breaker box in hopes of saving electricity. Breaker boxes were not designed to constantly be switched on and off. Therefore, turning off breakers unnecessarily can cause costly damage that outnumbers any energy savings. Only flip your breakers if absolutely necessary when troubleshooting an electrical issue.

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.
