"This is a great crew to work with! Friendly, knowledgeable, courteous, efficient, timely, and respectful. Phil answered all the questions that I asked (and there were a lot), he did this with patience and detailed responses. The crew arrived on time, they completed the job in one day, they were respectful of my property, and friendly while completing the task. I've had my panels for a few years now, the panels work great and if I have questions or concerns, Phil is happy to assist. Mr. Sunshine Solar provides complete customer service. Thank you!"

"Ryan was patient and allowed me to ask questions and did not pressure me. If I get approval, from HOA, will hire Ryan to do my solar on the condominium. If approval is not met with the HOA, I will be referring him out and using Sunpower on my next single-family home purchase."

"My pump was leaking and getting worse. I had used Matt before and he did a good job. I gave him a call and he came over, checked out the pump and said I need a new one.  When he told me the price, I decided to try to fix the pump myself. So after spending $375.00 on parts, the pump lasted a few more months before it seized. I called Matt and he came over on a Saturday to replace the pump. I should have listened to Matt in the first place. Now I have a super-quiet, energy efficient pool pump. They even cleaned the pool before they left. Just call Matt."

Energy Efficiency Auditing FAQs, answered by experts

Home power is measured in kilowatt-hours, commonly expressed as kWh. The average home uses between 800 and 1,000 kWh per month. Peak usage (and highest bills) occurs in the middle of summer and the depths of winter. Keeping on top of your usage during these crucial months will lower your annual average usage considerably. 

A blower door test shouldn’t take more than an hour, and most can be completed in less than 30 minutes. Expect the test to take longer once you start searching for leaks with thermal imaging or want to include sealing such leaks in the time estimate. The test doesn’t take much time and can’t be rushed, but it will take longer in large homes or those with many air leaks.

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.

Leaving lights on raises the electric bill, but not as much as having high-wattage light bulbs. The best way to save on electric costs is to swap your light bulbs to LED or CFL bulbs that use far fewer watts. You can also use smart lights and light switches to control usage via a smartphone or voice-controlled device.

Yes, installing an attic fan can help lower your electric bill—particularly if you live in a hot and humid region. By replacing hot and stuffy air with cooler air, these fans help regulate the temperature in your attic and the rest of your home, taking some of the pressure off of your air conditioner.
