"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."

"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.

"I've used Canoga Park Heating and Air for years now. I get the yearly Service Contract so they come out twice a year and check out the system, change the filters and make sure everything is working well. They notify me when it's time for service, so I don't have to worry about it. I highly recommend them. Jose Garcia did a great job, they are clean and respectful."

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.

There are a few ways to reduce your electricity bills if you use window AC units to keep cool. Set the unit temperature at least 1 degree higher than it is currently to reduce costs. Keep the unit clean for it to run efficiently. You may want to hire a window AC specialist near you to inspect the unit once a year and keep it in tip-top shape.

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, mini-split or ductless AC systems add value to a home and do not devalue it. They are an attractive feature for potential buyers, especially in older homes without existing ductwork, as they provide a practical air conditioning solution without the significant expense and hassle of installing traditional ducts. Ductless systems also eliminate issues associated with conventional ductwork, such as noise and the potential for pests. Furthermore, homeowners value energy-efficient solutions, and mini-splits offer high efficiency for both heating and cooling, plus zoned temperature control. This leads to lower energy consumption and reduced electric bills, which is a major selling point.

Blower door tests are measured in a few different ways, but the most popular are air changes per hour (ACH) and cubic feet of air (CFM) moving through the house per hour. A good ACH score is less than 2ACH, but 1ACH is better. This means the house experiences a total air change within 60 minutes (for 1ACH). For 2ACH, there’s a complete change every 30 minutes, and so on. CFM scores are similar in that a lower score means less air change, and therefore less leakage.
