"Our furnace stopped working, bad news. Mike was here quickly, and fixed the unit we have so we again would have heat! He explained what problems we were having and what we can do in the future to limit additional problems. Very knowledgeable, professional and personable! Our hero for the week!"

"The whole process was professional. From the initial call to completion of the project they were clear on what needed to be done and followed through with what they said they would do. They even worked on one small area that they weren't required too. Although no mold was present in the area there had been a little water damage there so they cleaned and sealed it to make sure. Their pricing was in the middle of the estimates I received but I decided to go with them after reading some reviews as well as the professional attitude they exhibited toward the estimate.

However, poorly insulated or older skylights can contribute to heat loss in winter and excess heat gain in summer, lowering overall energy efficiency.

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.
