"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!"

"Our Service Tech, Alex Peck, arrived on time to perform the annual check up & tune-up of our HVAC System. He was very professional and following the Tune-Up asked if there was any other items that needed done or looked into that he could take care of. His services were very much appreciated and very professional. Lee"

"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

Installing weather stripping or upgrading to insulated panels can improve efficiency.

A home energy audit costs about $420 on average, with prices ranging from $100 to $2,250 or more. The final cost depends on factors like your home's size, location, the thoroughness of the audit, and the specific tests performed. A basic Level 1 walk-through inspection typically costs between $150 and $200, while a comprehensive Level 3 audit with detailed testing and a report costs around $900. Homeowners may be able to use the 2022 Inflation Reduction Act’s Energy Efficient Home Improvement credit to cover up to $150 of the audit cost.

Costs for common individual tests include:

  • Blower door test: $350

  • Duct testing: $100

  • HERS test: $375

  • HERS certification: $200

  • Infrared imaging: $200

DIY is possible with basic tools. Professional audits provide comprehensive assessments and tailored recommendations.

You can save money on heating oil through a combination of improving home efficiency and smart purchasing strategies.

Home Efficiency and Usage:

  • Improve Insulation: Ensure your home, especially the basement and attic, is well-insulated and sealed against drafts to prevent heat leakage.

  • Manage Your Thermostat: Use a properly calibrated and programmable thermostat. Lower the temperature by a few degrees, particularly when you are away from home or asleep.

Purchasing Strategies:

  • Buy in the Off-Season: Order heating oil during the summer months when prices are generally at their lowest. This strategy is most effective if you have a large primary tank or a separate storage tank to accommodate bulk deliveries.

  • Consider a Delivery Contract: Some companies offer contracts with a set price for the term. This can lead to savings if market prices for oil increase, but you might pay more if prices drop.

Solar water heating systems are not one-size-fits-all. You'll likely work with a team of experts to get the job done—including solar panel installers, plumbers, and water heater installers. A specialist will help you decide if a passive or active system is best for your local weather, home layout, roof stability, and your budget.
