"Mohammed handled our project—sealing and insulating our attic. He was very knowledgeable about the best way to accomplish the task in an older home such as ours; and he also ensured that our project qualified for relevant energy rebates. He was professional and courteous in answering all our questions and completed the project in one day. We highly recommend HESS and Mohammed El-Goul."

Our reputation is based on service, safety, and quality, regardless of how large, or small the job.

"We had an energy audit done by Kyle Farrell in mid-September, and due to an alleged broken phone, this audit was not fully completed until the end of October. We tried multiple times to reach out and get ahold of Kyle, but he does not respond to messages or answer his phone. When we finally got him to come finish the audit (we had to go through the main company's page to complain to get a response) he told me he trashed his phone playing golf, and that they were "really busy" with other jobs as an excuse. Mind you, this was over a month after the initial audit visit. He then promised us his "window guy" would reach out to start the process to give us a quote. It has been days and we have heard nothing. We were having the audit done to take advantage of tax credits, which expire this year. We lost a month to get the work done due to Kyle's poor time management skills & failure to respond, and we will likely miss out on the tax credit as the timeline is too short. Would not recommend.

"The company deserves 1000 stars l. Chris came and gave a well thorough inspection and estimate of my actic. Had my concerns and expectations, I had several other companies come and give quotes for double the price. Especially ORKIN. Orkin tried to use care tactics to sign contract without any explanation. Chris gave the quote and the crew arrived a week later as scheduled. Chris has a great work crew who were professional , caring, and did high quality work. Every step of the way, I was communicated and was filled in. I was shown before , during and after photos. And end results were UNBELIEVABLE Chris is fair and honest, he gives reasonable prices and will not take advantage of his customers."

Energy Efficiency Auditing questions, answered by experts

Fireplaces can theoretically help you save on heating bills if you lower the temperature throughout the rest of your home and heat only a single room that you occupy using the fireplace. However, in most cases, homeowners won’t save any money on heating bills. Gas and electric fireplace inserts could actually lead to a spike in your respective energy bills if you use them frequently, and if you don’t keep up with chimney maintenance and repairs, your traditional masonry fireplace could actually be a source of heat loss in the winter.

When combined with a substantial solar system, if you have enough Powerwalls, you could go off-grid and be energy independent. But remember, you'd need enough Powerwalls to power your whole home continuously because a single Powerwall can’t power large appliances for extended periods. One Powerwall is able to power an average-sized home's emergency circuits, lights, and outlets. To power large appliances, you likely need two or three Powerwalls.

Not all homes are suited for solar panel systems. Older roofs or those in poor condition may need repairs or replacement before solar panels can be installed. Some other factors to consider are the amount of sunlight your roof receives, the roof’s orientation and pitch, and any shading from nearby trees or buildings.

A whole-home humidifier can impact your energy bill positively. In colder months, humidified air feels warmer, allowing you to lower your thermostat without sacrificing comfort. This can lead to energy savings as your heating system works more efficiently. However, it's crucial to use the humidifier judiciously to avoid excessive humidity, which might strain your cooling system in warmer months.

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.
