"Rep. checked entire system. He found several wires not connected properly and fixed this. He also made recommendations regarding the attachment of the panels to the rood that would provide more stability and leakproofing. The representative appeared to know what he was doing - much better than others, including the representative who was engaged by the roofer (who replaced our rood due to hail damage) to disconnect/connect the panels."

Energy Efficiency Auditing FAQs, answered by experts

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

Costs depend on pipe length, accessibility, and whether additional services are required.

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.

Yes, most audits include a report with prioritized recommendations for improving energy efficiency. Confirm with your auditor.

Leaving vents open but closing doors in unused rooms will probably not save money on your energy bill. Closed doors prevent the natural flow of air throughout the home, which could reduce the efficiency of the overall HVAC system. They could also restrict airflow into and through the return vents, making the HVAC system less efficient.
