"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."

"Matt has done various extra jobs for me that pertain to maintaining my pool.  A pump replacement that was required resulted in a reduction in my electric bill....just as he said it would.  Also, I had a light out in the pool that three other companies said they could not fix.  Some tried and could not fix it because they couldn't get the wiring out due to too many "U" turns in the wiring.  Matt said he could fix it and I had my doubts.  He came and had it fixed and working in about 1 hour!

Energy Efficiency Auditing FAQs, answered by experts

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.

Replacing a window frame will improve your home’s energy efficiency if the old frame is cracked or damaged in a way that allows unconditioned air from the outside into your living space or if you upgrade to a more energy-efficient window frame material. Aluminum is the least energy-efficient window frame material, followed by vinyl and wood. Fiberglass and composite frames are the most energy-efficient.

Homeowners may qualify for an HVAC tax credit if they install an ENERGY STAR®-certified HVAC system that exceeds the energy efficiency minimum standards:

  • Split-System AC: 16 SEER2

  • Packaged AC: 15.2 SEER2 and 11.5 EER2

  • Ducted Split Heat Pump: 15.2 SEER2, 7.8 HSPF2, and 11.7 EER2 

  • Packaged Heat Pump: 15.2 SEER2, 7.2 HSPF2, and 10.6 EER2

  • Mini-Split System: 16 SEER2, 9 HSPF2, and 12 EER2

You can claim up to 30% of the cost of the job, subject to maximums.

Keep the unit full but not overloaded, ensure door seals are tight, set correct temperatures, and avoid frequent door openings. Position the appliance away from heat sources for optimal performance.

STC (Sound Transmission Class) is a rating that describes how well a building material or assembly blocks airborne sound. A higher STC rating means less noise will pass through the material, providing better sound reduction. This rating system applies to various building components, including windows, doors, flooring, drywall, and insulation.

For context, a typical single-pane window has an STC rating of around 25 (where normal conversations are audible), while a well-sealed, double-pane window can exceed STC 45 (blocking loud speech and most music). It is important to note that for some products, like soundproofing drywall, the STC rating refers to the entire wall system, not just the individual panel.

Additionally, STC ratings are most effective for measuring sound reduction at mid-to-high frequencies, such as human speech, and may not accurately reflect how well a material blocks low-frequency sounds like bass music or thunder. Because of these factors, it is recommended to consult a professional to determine the right STC-rated materials for your specific soundproofing needs.
